Hi,

If for your Portlet A you want to access services of portlet B. In liferay-plugin-package.properties file you need to enter below entry.

File liferay-plugin-package.properties you can locate inside WEB-INF folder.
required-deployment-contexts=\
portletB
When you deploy portletA you can check logs. Before deploying portletA it will check for portletB. It shall build portletB first and then copy service jar from portletB into PortletA.

HTH!

Hi,
Thanks for your reply manali now it's working fine

No. Portlets do not share context between them; any services, data or beans created in one are not visible or accessible in another.

Actually if I had to guess I'd say maybe there's a newer version of the portletB service jar being used by A, newer in that the service jar refers to the PodEngineUserLocalService bean but if portletB was not deployed with the update, you could get a no such bean exception.

Normally the service build number prevents these kinds of oddballs from coming up, but you could always have a service-ext.properties in portletB that hard-codes the service number (I sometimes do this because I'm only adding to a service layer and don't want to force a redeploy on every dependent portlet).

So the big question is, did you deploy the updated portletB or are you only pushing out the updated service jar in each of the ways listed?

Thanks for your reply David,

I have deployed updated service jar only i got your point now what i did is i copied the jar file and paste it in globalclasspath and can you please give one example for me how to change build number using service-ext.properties.
But now my issue was cleared i followed what Manali suggested me.

Thanks & Regards
