WebLogic Application Deployment & Shared Library Important point

remember always keep separate jar and war ...

combined  all jar in single war and put this war as reference library in weblogic after that create war using IDE or .any other way and link both using hot deployment.. that it ..refer other wise ..below link

WebLogic Application Deployment & Shared Library

WebLogic server offers the shared library concept using which EARs, JARs, EJBs and WARs can be shared across applications in a WebLogic domain.

Let us now see how to package and deploy a shared library in WebLogic server;

Step 1: Create a folder structure as shown below

Step 2: Copy all the libraries (in this case JAR files) that you would want to share across applications to the lib folder under WEB_INF
Step 3: Create a file under META_INF folder by name "MANIFEST.MF"
Step 4: Contents of the MANIFEST.MF file are shown below

Manifest-Version: 1.0 Specification-Title: CommonJars Specification-Version: 1.0 Implementation-Title: CommonJars Implementation Implementation-Version: 1.0 Implementation-Vendor: Oracle Extension-Name: CommonJars

Step 5: From the root folder location, execute the following command to generate a WAR file

?

1	jar -cvf sharedlib.war *.*

Step 6: Now, login to Oracle WebLogic console, choose "Deployments" and deploy the generated WAR as a shared library - steps with screenshots below

Step 7: Now that the shared library is deployed, let us refer this shared library from another application

Open the weblogic.xml file. If it is not present in your application, create this file under WEB-INF folder of your application and refer the shared library as shown below;

<?xml version = '1.0' encoding = 'windows-1252'?> <weblogic-web-app xmlns="http://www.bea.com/ns/weblogic/weblogic-web-app">     <library-ref>         <library-name>CommonJars</library-name>     </library-ref> </weblogic-web-app>

Enjoy sharing libraries across your enterprise applications.
