Web Services

A Web service is a method of communication between two electronic devices over a network. It is a software function provided at a network address over the Web with the service always on as in the concept of utility computing. A web service has an interface described in Web Services Description Language (WSDL). Other systems interact with the Web service in a manner prescribed by its description using SOAP (Simple Object Access Protocol) messages. There are two major classes of Web services: REST-compliant web services, and Arbitrary web services.

Answering your cyber security questions
Answering your cyber security questions

It’s in the news. It’s the job title of the main character on every other tech thriller on TV and in the movies. It’s the hot topic in business boardrooms, university classrooms, and just about everywhere else. But what is cyber security, and how do you get a job in it?

I am running Ubuntu 14.04.5 LTS in Amazon Web Services with an Elastic IP and an inbound connection for my Static IP.

I need to simply copy files from Ubuntu (Ubuntu 14.04.5) to my local mac (running OS 10.14.2) and then copy them back, both using a Terminal window and SSH.

I've tried scp, but can't seem to get the command correct as the error I'm getting is:

"ssh: connect to host **.*.**.*.** port 22: Connection timed out" (This IP is the Elastic IP).

What am I doing wrong? Help! Thanks in advance. :-)

We have a web application that uses an external SMTP server to send emails.
We add CNAME records on our client's domain names so that the SMTP can send emails on their behalf. We don't have any issues so far, just with one of our clients in one specific situation.

If the application sends an email with our client's domain as the FROM to any email address other than their own domain, the email goes out without any issues.
If the application sends an email from any email address other than the client's domain and sends it to the clients domain, the email goes out without any issues.

BUT

If the application sends an email from an email address of our client's domain to another email address from the same domain, then the email doesn't even make it to the SMTP server. We checked the logs and there is no record of the email being processed.

What could possibly cause this?

Hello,

I generated soap web services using Eclipse JEE, which then I deployed ( .war) on Tomcat 7.0 on Centos 7 -  this works fine.
The aim is to insert a data received in an xml and insert it to an Oracle table.

I've added the below code to a java class file, which meant to do some insert statement ( which is valid ) , with hardcoded values, just to prove I can do it.

    public void InsertValue(String MessageId, String value){
    	try{

    	Connection con=null;
    	Class.forName("oracle.jdbc.driver.OracleDriver");


    	con=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xxx", "xxx","xxx");
    	Statement s = con.createStatement();

    	s.execute("INSERT INTO ping_message (message_id,dstamp) VALUES ('1',To_char(SYSDATE))");
    	con.setAutoCommit(true);
    	s.close();
    	con.close();
    	}catch(Exception e){
    	System.out.println("ERROR: "+e.getMessage());
    	}
    	}
    

Open in new window


Unfortunately, this does not work. I wonder if this is because of the java code or Tomcat needs some db drivers in order to establish a connection the database ?

btw, my java skills are being developed as I type this :)

Hi Guys,

I wonder if anyone has any experience in calling an oracle procedure/function using APIs ?
I've been reading about JDeveloper, APEX and Oracle App server and I'm a little bit confused with all my findings and the best approach.
What I need is
1. receive a SOAP API call
2. Trigger an oracle function
3. Send a response back

I have already a web server running ( hosted web app - Apache-HttpClient). However, an oracle is on a different box.

Hi,

We have a HP PageWide Pro 477dw printer which we use for scanning and printing and have no problems with printing word or excel documents.

When we go to print a report from Linkedln using our Windows 10 Pro PC, we get a page printed out which states "PCL XL Error" with "Error: InsufficientMemory".

How do we resolve this problem?

Thanks,

I need to convert the CURL POST command below to vba (access).  I'm very proficient with access vba but not anything web-based so any direction on learning materials would be also appreciated.  I found and modified an example that I thought might work (code below), but it just gives the error "ActiveX can't create the object.  Suggestions?

CURL COMMAND:
curl -X POST -H "Content-type: application/json" -H "Accept: application/json" -d '{"shop": "9999999999","client_code": "88888888888.","lastname": "Ender","phonenumber": "5555555559","vehicle_year": "1999","vehicle_make": "JEEP","vehicle_model": "something" }' http://somewebsite.com/api/customers

VBA CODE (Fails with error above):

Private Sub cmdCreateAutoTextCustomer_Click()
Dim sURL As String, sHTML As String
Dim oHttp As Object
Dim Body As String
'‘Add a reference to the MSXML type library
Set oHttp = CreateObject("MSXML3.ServerXMLHTTP")

'‘The website to post to
sURL = "http://somewebsite.com/api/customers"

'‘ The json string to send.
Body = "{""shop_number"": ""9729925026"",""client_code"": ""142KukK231k."",""lastname"": ""Ender"",""phonenumber"": ""5555555559"",""vehicle_year"": ""2009"",""vehicle_make"": ""JEEP"",""vehicle_model"": ""something"" }"

oHttp.Open "POST", sURL, False
oHttp.setRequestHeader ' "Content - type", "application / json" '
oHttp.setRequestHeader '"Accept”, "application / json"'

'‘Send the json
oHttp.send (Body)

'‘Server response.
sHTML = oHttp.responseText

I've messed up. Entered an incorrect string into the Web Services Configuration under ciphers and now the cPanel will not connect saying invalid connection. How do I get into the cipher section of the Web Services Configuration using SSH and command line please? This is the silliest thing I think I've ever done on a CentOS 6.x server - it's a live server so my clients are now not able to see their websites.

I tried to move the sites on the server to another server using the Transfer tool but that fails too, saying SSL connect attempt failed - unsupported protocol.

I can ssh into the server so I'm hoping that I can resolve the issue by using SSH from the command line.

Any urgent responses greatly appreciated.

IT Pros Agree: AI and Machine Learning Key

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

Hello Experts,
This is the first time I am going to use WEB SERVICES
I have to send one or more XML files inside a folder that is zipped.

and I have a URL address... a username and a password.

also got a Digital certificate and the public key is already uploaded and properly registered.

Can you send me a simple example source code in
visual basic or visual c# on how to do this?

Need to create a page in WordPress that would connect to the API and display a search form and list of items from an external API:

Example that needs to be achieved:

http://www.pharmachoice.com/health-advice/medical-conditions

Info about Webservices:

Conditions
Specification: http://webservice.mediresource.com/mridisease.asmx?WSDL

URL: http://webservice.mediresource.com/mriDisease.asmx?op=GetDiseaseInfo

Changeable Variables:
•      strDiseaseInput – any text string (ie. cancer, blood, nose, etc.)
•      intDiseaseID – disease id
•      strAlpha – letter of the alphabet (ie. a, b, c, etc.)

Set Variables
•      intChannelID = 0
•      intLanguageId = 0 (English) / 1 (French)
•      intCountryID = 0
•      strWsKey = {removed}
•      intCaptureOne = 0
•      intCaptureTwo = 0
•      intCaptureThree = 0
•      intCaptureFour = 0
•      intCaptureFive = 0

I have not had the chance to work with API's in the past, so any insight will be very helpful.

Thank you very much!

I am trying to reverse engineer someone else's Apache web server configuration setup.      

There are two RHEL 6 servers running 2.2 Apache web services.   Apache is being used to front-end a JAVA tomcat application.
On one server, the Apache log files are owned by the tomcat user.  
On the second server, the logs are owned by root.    

By corporate standards, the designated Apache log directory only allows 2 GB worth of data.   We exceed that on a regular basis and must route the logs to a subdirectory of the application and allow that application's log maintenance system to periodically archive the files.   However, the root owned log file permissions do not allow the tomcat user to perform cleanup maintenance.   Making the tomcat user the log owner resolves that problem.

ps aux show that both servers run apache using the apache user.    


I've looked in httpd.conf (and secondary files included by it)  and logrotate.d and cannot find a config file entry which explains the difference in log owner.   Can someone point me to a likely suspect?   The tomcat application's documentation does not address this problem.

Thank you.

I am setting up an integration with a third party.   They already have an existing POST to a former affiliate, so I ask them to just put my URL in there and hit our site.  I figured I would just deserialize the JSON and see what comes in, then code to that.  

So I created a   index.cfm file (Coldfusion 11)  on    www.mysite.com/api/order/    

The index.cfm file does nothing but email me a CFDUMP of the URL and FORM variables.
I gave the URL to the company and they hit it.   I receive the email and both CFDUMPs are empty structures.   No URL variables, no FORM variables.

They say they are doing a POST call to the site.   And are using this path:     www.mysite.com/api/order/   

They have hit it multiple times, they get a 200 OK response.   But each time, my mailed dump show empty values even though they are sending JSON over.

What am I missing?    What do I have to do differently to see the data they are sending?

Thanks!

Looking for a way to automatically add Google calendar events from a website that is filtered for my state.  This Website Events Page    

I have looked into IFTTT, and general google searches and have not found anything thus far.   I have IT scripting/automation background but have little experience in this realm.  Looking at the page through the developer tools in chrome, I didn't see an easy way to pull the data.

Is there a tool or way to pull this data, perhaps coupled with an online tool such as IFTTTT, that would create /update events in a secondary calendar in google?

sample.phpRunning, or utilising PHP scripts from VB6.

I have a large VB6 application which I developed over many years, and has been operating for many many years now.

My software has no issue consuming Web Services using MSXML2 to call various XML and JSON feeds.

However, in this instance, I need to communicate back and forward, and I'm slightly stumped as to best way to move forward. I've been presented with a PHP code which (a) has a login function to get a authorisation code, and (b) using that authorisation code, I need to send variables to submit a transaction, which supposedly will return a response.

I've attached the basic (modified) PHP script, and I'm looking for "nudges" in the right direction. The variables needed to pass to the login function, and order function are contained in my vb6 software.

Much Appreciated any assistance.

The CompTIA Cloud+ Basic training course will teach you about cloud concepts and models, data storage, networking, and network infrastructure.

We have an own PKI.
I have created a new certificate for some web services.
I just want to get rid of the cert warnings when I open the site.

When I open the site with IE all is fine and no warnings.

C# web service calling another .NET assembly using reflection
I use a web service to a run-time assembly call using C# Reflection.
The assembly is in Binary format in database. All records contains a binary data which is almost same in structure. It has a Start method in a class called 'MyAssembly'
First I loads assembly object using  the Binary data, then finds the type - MyAssembly from it and then calls a method 'Start'. The start will write the logs into a directory. This works entirely fine when we call from an executable. All executables goes into separate process ID and the results are getting.

Then calling the same step using a Web service hosted in IIS, the results are getting messed up. Simultaneous calls to the same method gets the results into different different calls.
Example: Method1 called using web service and the logs are writing into File1.
Method1 again called using different arguments and the logs are writing into File2.
When calling method1 two times at the same point of time using web service, gets the logs messed up, File1 details are showing in File2 and File2 are in File1. It is not only the logs issue bug also the execution are getting wrong that inner methods are not getting proper outputs and return values. Everything messed up.

When the web service is calling EXE program (Which is not allowed in so many conditions) - That is without finding out the method using reflection and then calling it, it just calls an exe program using …

I'm getting the following error:
<soap:Fault xmlns:env="http://www.w3.org/2003/05/soap-envelope">
      <faultcode>env:Sender</faultcode>
      <faultstring>Invalid version of SOAP in the request. SOAP 1.2 must be used. </faultstring>
    </soap:Fault>

Open in new window


How do I pro grammatically or using a config file change the SOAP to 1.2?

I have tried putting this line on the interface file but does not seem to be working. @BindingType(javax.xml.ws.soap.SOAPBinding.SOAP12HTTP_BINDING)

I'm currently call the service like this:
LoggingInInterceptor loggingInInterceptor = new LoggingInInterceptor();
            loggingInInterceptor.setPrettyLogging(true);
            LoggingOutInterceptor loggingOutInterceptor = new LoggingOutInterceptor();
loggingOutInterceptor.setPrettyLogging(true);

CORETransactionService service = new CORETransactionService();
CORETransaction port = service.getCoreSoapPort();

Client client = ClientProxy.getClient(port);
Endpoint endpoint = client.getEndpoint();

endpoint.getInInterceptors().add(loggingInInterceptor);
endpoint.getOutInterceptors().add(loggingOutInterceptor);

Map<String, Object> ctx = ((javax.xml.ws.BindingProvider)port).getRequestContext();

I'm trying to set the SOAP Request to 1.2.  So with some research I see that you can accomplish this using the following code.

Service service = Service.create(servName);
service.addPort(portName, SOAPBinding.SOAP11HTTP_BINDING, ServerMisc.DOCLIT_CODEFIRST_URL)

Where do I get portName from?

I have a java web service that is supposed to start automatically when it is deployed.  For some unknown reason it does not.  I am seeking guidance on how to figure out why it is not starting automatically.  I am using jdk 1.8, jax ws 2.2.6, tomcat 8 on rhel 7.  Here is what I have in the web.xml file for the service servlet:
    <listener>
        <listener-class>com.sun.xml.ws.transport.http.servlet.WSServletContextListener</listener-class>
    </listener>
    <servlet>
        <servlet-name>MiscService</servlet-name>
        <servlet-class>com.sun.xml.ws.transport.http.servlet.WSServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>MiscService</servlet-name>
        <url-pattern>/MiscService</url-pattern>
    </servlet-mapping>

Open in new window


Is there something else I am supposed to do other than put the number 1 in the load on startup tag?  Everything that I have googled said that this is all I need to do.  My server admin guy is not much help and if there is something on the server side that needs to be done can anybody please tell me that.  If there is something else that I need to put in my code then please let me know.

I do not have this issue in the development or staging environments but I can say that the one difference in the production environment, which is where I am having this issue, is that the web service is served via a load balancer.  The request goes through one of two regular apache web server to tomcat.

HELP!!!
