Two WAR files to an EAR

[Ramu Nur]

Hi
We have to create an EAR file that should have two WAR files. But these two WAR files share common application libraries. The two WAR files are build and added to EAR. When this EAR is deployed, the common classes are loaded twice resulting in duplicate schedulers. How can these common libraries be loaded only once? should they be removed from one WAR file?

Thanks in adv

move those libraries at ear file level.
so both web applications can load from there.

Thanks for reply. So, should the common jars go to WEB-INF\lib of EAR file? I know EAR has a META-INF, applicatoin.xml.

you can try leave them in the root of the ear file.
ear file doesn't have a WEB-INF, only war files.

If you are using WebLogic then the jars can go into /APP-INF/lib (this is in the root of the ear file)

ABC.ear
- application.xml
- meta-inf
- xyz.war
- 123.war
- common1.jar
- common2.jar

Is it this way?

[German Gonzalez-Morris]

yes.

anyway which app container are you using ?

Please do not create multiple threads for the same question. I'm closing the other one https://coderanch.com/t/562508/EJB-JEE/java/Two-WAR-files-have-common.

This is for jboss. The actual problem is, there are some dao classes and quartz schedulers in those common jars. they are started when war is deployed. If they are common, when two wars are deployed, the schedulers, dao connections etc are loaded twice. I want to avoid that.

any clues?

Did you read the replies in the other thread?

Why don't you configure your project with maven. You just need to add dependencies to your application project and maven handles everything else..
