Can't find component /atg/dynamo/servlet/adminpipeline/AdminHandler

Question

I hope someone will be able to help because i am struggling with this issue for two weeks now, and still not been able to find a solution.

I have got JBoss AP server installed on my Red Hat Linux machine. I am trying to trigger a build and deploy my application after the new changes in code i have made. During the deployment process, right after the server is stopped, and started again, i get the following error and the build/deployment just fails:

ERROR [org.apache.catalina.core.ContainerBase] Servlet.service() for servlet

I have gone through ATG Installation documentation several times, have tried what is suggested there but doesn't work. During the search i found that the AdminHandler component that is been missing, is a component that is inluded when installing ATG platform.

I never had this kind of problem before, but one day two weeks ago, this started appearing.

Any thoughts?

Thank you !

Answer 1

For this first you need to check that do you have /DAFEAR/Admin folder. If this is not exist then you need to install the ATG Dynamo. And if exist then re-compile your module with DafEar.Admin module.

runAssembler <yourmodule.ear> –m yourmodule DafEar.Admin

Hope this will help you.

Answer 2

Could you try fresh ATG installation? And follow precisely ATG Installation Guide, after that I hope your problems will gone.
