Deploy the WAR file using the WebSphere deployment tools.
If you are using WebSphere 6.1, you need to update the ibm-web-ext.xmi file after deploying the WAR. You need to add an entry similar to the following in the ibm-web-ext.xmi file after the WAR has been deployed:
<jspAttributes xmi:id="JSPAttribute_3" name="jdkSourceLevel" value="15"/>
The name must be jdkSourceLevel and the value must 15. You will need to use _3 or above for the JSPAttribute id. For more information, see the following links:
After completing the deployment of the WAR, perform these steps:
Stop the WebSphere Application Server.
Modify the ibm-web-ext.xmi file, as described above. The file location should be specified in your IBM documentation. For example, the file might be at this location:
/opt/IBM/WebSphere/AppServer/profiles/AppSrv01/installedApps/MyNode01Cell/IDMProv_war.ear/IDMProv.war/WEB-INF
Restart the WebSphere Application Server.
