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.

Why Off-Site Backups Are The Only Way To Go
Why Off-Site Backups Are The Only Way To Go

You are probably backing up your data—but how and where? Ransomware is on the rise and there are variants that specifically target backups. Read on to discover why off-site is the way to go.

Hi Experts,

I did a Nessus scan and received a high vulnerability finding and have a few questions.

This result was from scanning our domain controller(wind 2012 R2).

First how did a certificate get generated when we do not use IIS on this DC? as i do not understand why a certificate would need to be generated on the DC or how it would be? We do not have a CA.

SSL Certificate Cannot Be Trusted


The server's X.509 certificate cannot be trusted. This situation can occur in three different ways, in which the chain of trust can be broken, as stated below :

 - First, the top of the certificate chain sent by the server might not be descended from a known public certificate authority. This can occur either when the top of the chain is an unrecognized, self-signed certificate, or when intermediate certificates are missing that would connect the top of the certificate chain to a known public certificate authority.

 - Second, the certificate chain may contain a certificate that is not valid at the time of the scan. This can occur either when the scan occurs before one of the certificate's 'notBefore' dates, or after one of the certificate's 'notAfter' dates.

 - Third, the certificate chain may contain a signature that either didn't match the certificate's information or could not be verified. Bad signatures can be fixed by getting the certificate with the bad signature to be re-signed by its issuer. Signatures that could not be verified are the…
What other programming languages for web service development?  Which is better PHP or html?

I am using self written Java programmes at home that consume SOAP web services from my rc plane club. So far everything works good, But sometimes the SOAP web services that I use are not available due to maintnance or problems at the club's server. I want to monitor the availability of the SOAP services and persist the status. When I use the SOAP services the programme shall first check the availability from the monitor and if the status is 'available' perform the desired request or else queue the request until the service becomes available again.

Before I start to re-invent the wheel and write my own monitor I wanted to know if there are already tools that can accomplish this task, which can be easily embedded or used in Java before a request.

Best regards,
The code below is executed when a user clicks a button.
It asks the user for a username/password and tries to upload a file to a webservice.
When the username/password combination is correct, everything works fine. But when the user types an incorrect username/password combination, this functions crashes. ( which is normal, because authentication failed...) .
After such a crash, the code no longer works, even after rerunning the same procedure this time with the correct username/password combination.

The only solution I found is to restart the whole application... There has to be a better way?
Does the HTTPRIO object cache my incorrect username/password? Or .... ?

RIO := THTTPRIO.Create(nil);
RIO.HTTPWebNode.UserName :=Username;
RIO.HTTPWebNode.Password :=PassWord;
webserver := GetCRS( True, '' , RIO );

 // get file to upload and encode it in base64
 myFileToUpload := TByteDynArray( TEncoding.UTF8.GetBytes( xml.XML.Text ) );

// create upload file request object
myUploadFileRequest := UploadFileRequest.Create;
myUploadFileRequest.UploadFile := PayLoadType( myFileToUpload );

// upload file to server
 myUploadFileResponse := webserver.uploadFile_A2A( myUploadFileRequest ); --> Crash

This is using Amazon web services. This EC2 instance was created using Elastic beanstalk. Using this Elastic Beanstalk, 1 EC2 and 1 S3, plus some other components are created. This EC2 is also having php and MySQL, so it is a LAMP server. It is used to serve dynamic web applications.

Now, I want to setup cloudfront for SSL cert and faster data delivery. I follow the normal steps > choose web delivery, configure origin, distribution, and cache behaviour. I also made use of the route 53 for the public hostname to be pointed to relevant cloudnet. I waited this cloudfront distribution to be "deployed". However, when I access to the web with https, an error message prompts:

cloudfront attempted to establish a connection with the origin, but either the attempt failed or the origin closed the connection.

What would be standard ways of setting up this cloudfront to work with EC2 (LAMP)?

We have a local oracle database 12c.

Another remote system (mysql/java) needs to post a record of data each time a transaction is executed by a user to our local database.

The way it will work is the remote system will call a web service in local database (https) and submits data using CSV format.

Can CSV format support web services and one to many table relationships?

My thinking is that it is fixed-size format and difficult to parse of you have one customre order with multiple line items or none.

Most of the web service I developed were using XML format before.
Hi all,

We use our internal CA using a SHA1 to create certificates for internal web services. We are now tasked with upgrading this to SHA2. My colleague has suggested we renew all SHA1 certificates so that nothing is set to expire within the next 12 months. We will then look to upgrade the rootCA but im concerned that once we do that all the web certificates will need to be upgraded?

Can someone clarify what happens when the ROOTCA is upgraded to SHA2?

It will be difficult to know whether all web services are SHA2 compatible, is there a way to create a separate SHA2 ROOT CA?
I have an XML file that when passed through SOAP UI returns a proper response as XML file. I need to create an application to pass the XML and recuperate the response. I tried searching but many say REST web service where they using only post/get.

Please send me some sample code and/or tutorials.

This is the direction we are heading; good ole' AWS. Thinking ahead; (kind of hard to ask with providing you more) do you guys who have done this have a road map or sample config that would show how to setup a Site to Site VPN to Amazon Web Services?

Thanks ahead of time Experts!!!
Hi Experts,

We are setting up a new automatic deployment environment.
After the process runs and everything gets deployed, we need to check
the health status of a list of windows and web services whose names we will have in some table or XML file.
For ex. there are 50 windows services say service1 to service50 in the xml for windows services.
We need to find the status of all those...and also names of those which are there in xml but did not get installed or deployed by automation process.(delta of services present in xml and not under services.msc).
Similary we need to test all web services listed in xml.
Please help with suggestions and sample code or articles.

I am a C# MVC .NET developer but have not yet heard much about what MicroSevices are.

For the past few months I've been a Beta tester for a new service called DNS Spy.  It's a service that Monitors, validates and verifies your DNS configurations.  

It might be worth a look if you are looking for something that monitors your External DNS.  Link below:
I've been asked to push some data to an external web service using Access 2010. After researching this all day, it looks like many suggestions point to using Visual Studio to create a dll that utilizes VS's ability to auto generate the web services protocol code, reference then dll in Access and then call it from my Access 2010 VBA code. The web service code works great when bundled as a standalone exe. However, when I compile it into a dll, reference it within Access and then call it from by Access VBA code, I get the following error:

"Could not find the default endpoint element that references contract 'ServiceReference1.NameOfMyDllClass' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element."

After a little more digging, it appears that creating a dll does not include the app.config file that contains this configuration information so I'm guessing my DLL can't find the configuration information it needs to initiate the web service transfer. Most recommendations seem to suggest adding the info in the app.config file to the host's app.config but off course Access does not have anything like that.

With so many recommendations to use dlls that wrap the web services when using Access, it sounds like a great way to go but I must be doing something wrong. Any help to get me pointed in …
