Using common classes across different portlets

shaipai Apr 27, 2011 2:08 AM

Hi,

I have some classes that are being used accross different portlets. The way I am doing is packaging the classes into a jar & then putting that jar into respective portlet war. The problem with this is any change to a common class will need repackaging of all the war files & deployment. Is there a better approach ?.

Do you mean some classes in war files are using a common library, and you'were putting lib into your war file?

I'm wondering that why you don't put the common library in TOMCAT/lib instead of in the war file if it's used by others

Are you using Maven for managing your project?
I think you can use Maven or Ant for this to manage dependencies and you simple configure parent pom.xml to make auto-build for all projects with one command .

Thanks everyone for your time to respond to my query. It helped. I put the common jar in \server\default\deploy\gatein.ear\lib. It worked. But is this the correct place ?.

this really depends on Web Application Server specification and your kind of packaging/deployment ( For instance, Tomcat & JBoss are not the same ). So I think you should refer to the specific Web Application Server documentation, to see its file system management and loading mechanism.

Check the link for documentation on class/resource loading mechanism in Tomcat
