Question

When I am deploying two portlets in liferay 6.0.6 on tomcat server one after another portlet, the second deploying portlet is undeploying the first deployed portlet and vice versa happening when changing its order:

Stacktrace:

Any Solution?

Answer 1

Looking at stack trace

Caused by: com.liferay.portal.OldServiceComponentException: Build namespace abc has build number 20 which is newer than 4

it seems you need to update build number.

Either change in service.properties or update build number in release_ table for particular portlet

you can refer to below Link

Answer 2

I have found the solution after lots of digging and fixed the issue, you can fix this via following steps:

1. before deployment of any portlet need to delete entry of pre-deployed portlets in lportal database from servicecomponent table via following command : eg: DELETE FROM servicecomponent WHERE buildNamespace = 'abc';

2. Now re-deploy your portlet will not throw exception: Caused by: com.liferay.portal.OldServiceComponentException: Build namespace abc has build number 20 which is newer than 4

Answer 3

Caused by: com.liferay.portal.OldServiceComponentException: Build namespace yourProject has build number x which is newer than y

Solution: go to service.properties change the build.number=x
