How to deploy JSP/Servlets in Weblogic8.1?

The installation didn't create DefaultWebApp for me, but there is a folder called "WebContent".

cheers
;-p

Should I create the DefaultWebApp folder manually??

After creating the DefaultWebApp folder in applications, created the WEB-INF\classes. Placed the jsp/html file in DefaultWebApp, but its throwing Error 404. When I opened the http://localhost:7001/console, there is no problem, but only when tried to access the JSP page thru http://localhost:7001/index.jsp - Error 404.
Pls advise.

check your installation , a DefaultWebApp folder is created by default in the
\config\mydomain\applications\Folder..

However you can create your own webApp folder..
in the console got to
Deployments --> web applications -->configurel a new web application. now input the correct path. create a new folder inside your applications folder (say myWebApp).
give this as the path of your application.the full path starting from the drive.
set the target a sthe admin server.

DefaultWebApp is for a default admin server installation only.  If your server doesn't have one, and you created your own web application (make sure it's a valid web application that conforms to the servlet specification!!!), even if it's called "DefaultWebApp" you have to deploy it to the server.  On a weblogic server you can deploy a web application in many ways.  The easiest is to simply drop the web application folder or .war file into the server's staging directory (do a file --> find on the word "staging" under the BEA folder on the drive Weblogic is installed to).

Or, you can open Weblogic console, navigate to deployments --> Web applications, and manually deploy the application by following the prompts.

If auto-deploy doesn't work for you it may be because your server is set up for production mode only.  Usually this is a setting you can uncheck in the server's configuration tab in the console.  Restart the server afterwards.

HI,

You need to place your servlet within a web application, which is very simple, actually.  You create a folder, lets call it "HelloWebapp".  In that folder create another folder called "WEB-INF".  In WEB-INF create a folder called "Classes".  Compile your serlvet into the "Classes" folder.  Note, your servlet must be in a package, so if it isn't, create a package declaration at the top of your servlet, then make sure, when you compile it, that it's compiled in a folder with the same name as the package name, within in the "Classes" folder.

So, if your servlet is in package "myPackage", the .class file should reside in \HelloWebapp\WEB-INF\Classes\myPackage\HelloServlet.class

You're almost done creating a web application.  Next, you will need a simple web.xml descriptor that gives a web friendly name for your servlet, and points to the servlet.  Create a file called web.xml in the WEB-INF folder (but not in the classes folder).  Paste this inside the web.xml file and save it:

<!DOCTYPE web-app
    PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
    "http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app>

    <display-name>Hello World Web Application</display-name>
    <description>Test Servlet</description>
     
    <servlet>
        <servlet-name>HelloServlet</servlet-name>
        <servlet-class>myPackage.HelloServlet</servlet-class>
    </servlet>

    <servlet-mapping>
        <servlet-name>HelloServlet</servlet-name>
        <url-pattern>/HelloServlet</url-pattern>
    </servlet-mapping>

</web-app>

Now you have told Weblogic that the URI /HelloServlet corresponds to your servlet "myPackage.HelloServlet".

Your Web Application is ready to be deployed at this point.  Log into Weblogic's admin console, and click on deployments, then navigate to "Web Application Modules" (I'm using Weblogic 8.1 - if you're not your interface may be slightly different).  Be sure your Web Application is located somewhere on the same computer as your server at this point.

Click "Deploy new Web Application Module"
Navigate to the location of your web application folder (HelloWebApp).  There should be a radio button next to it indicating that you can select that folder as a valid web application.  Click the radio button and click "Target Module".
Select which server you want to deploy your web application on, then click continue.  At this point, since you're just testing, select the "I will make the web application module accessible from the following location".  You shouldn't have to enter text because the location you selected should already be there.   Just click the "Deploy" button.

After deployed, your web application will appear in the "Web Application Modules" tree on the left.  Click on your web application, click the testing tab, then click the link shown there.  It will not yet show you your servlet (will probably show a 404 error) because you don't have an index.html or index.jsp page.  Instead, add your servlet on to the URL it provided.  

So, if the URL it provided was http://localhost:7001/HelloWebApp/  make your URL http://localhost:7001/HelloWebApp/HelloServlet

i hope it may help you..

best of luck...
