Hi Tim
Let me describe the things in more details. Assume we have a main.war
file and we have a helper.war file. In the main.war file I have a jsp
page with a name main.jsp. On a main.jsp I have a link which actually
starts the helper functionality. So assume that this link actually calls
a servlet present in the helper.war. This servlet will show helper.jsp
to the user and captures inputs from the user. After doing some
processing the servlet present in the helper.war file should give some
output back to the main.war file. Keeping this flow in mind can you
kindly suggest me a better approach for implementation than copying the
source code of helper.war in the main.war?

We have many web modules in our project and all those web modules are
bundled in an EAR file. We have some helping functionality in our
project and those functionalities are common across many web modules.
These functionalities are also web modules themselves as they have JSP
screens to capture user input. If we try to package these helping
components in a web module (in a WAR file) then it becomes very
difficult for us to establish a dependency between the main WAR file and
the helper WAR file. In these circumstances the only way left to us is
to copy JSP files and class files of the helping component in each and
every main WAR files. I think this is not a clean solution. Ideally we
should package this helping component in a JAR file somehow and then we
should establish a dependency in the main WAR file by putting
appropriate entries in its MANIFEST.MF file. Can anybody suggest me how
to achieve this scenario by keeping our requirement in mind?

Maybe I'm missing something but why not just place the helper.war/.jar
in the classpath of the app. server, and deploy all of the .?ars
together? I'm not sure what dependency you want or need to declare.
Just deploy all the files together visible in the app. server's runtime
classpath.
