and is not starting after this line kindly help how to resolve this error.

Answer 1

1. Go to Weblogic's config.xml
2. Locate all <app-deployment> sections.
3. Delete them (you may want to backup it somewhere).

In my case it was more than thirty instances of our application:

<app-deployment>
    <name>deploy_ear_ear_exploded</name>
    <target>AdminServer</target>
    <module-type>ear</module-type>
    <source-path>*path_to_application*</source-path>
    <security-dd-model>DDOnly</security-dd-model>
  </app-deployment>

Answer 2

1. Stop the weblogic server
2. Remove all war files from the 'autodeploy' folder in weblogic.
3. Then start the weblogic server again
4. After that type the URL "http:// localhost:7001/console/" in browser
5. Go to " Configure applications" link
6. Then select previous projects and the go stop -> When work completes

Answer 3

For me works:

1) Uninstall all previous deployments (all ears)

2) Stop de server

3) Go to user_projects/domains/base_domain/servers/AdminServer/tmp and delete all content in this folder (you can back up the content)

4) Start and deploy

Answer 4

1. Start the server
2. Go to deployments ( http://localhost:7001/console/console.portal?_nfpb=true&_pageLabel=AppDeploymentsControlPage )
3. Remove war deployments
4. Then restart, it should works
