Java EE – what is the reason for the “duplicate entry” savefailureexception when deploying ear to WebSphere?

• Java

When trying to install ear, the following exception occurs:

Caught Exception installing ApplicationName  
com.ibm.ws.scripting.ScriptingException: com.ibm.websphere.management.application.client.AppDeploymentException: AppDeploymentException: []  
org.eclipse.jst.j2ee.commonarchivecore.internal.exception.SaveFailureException: Meta-INF/application.xml  
Meta-INF/application.xml  
duplicate entry: Meta-INF/application.xml  
org.eclipse.jst.j2ee.commonarchivecore.internal.exception.SaveFailureException: org.eclipse.jst.j2ee.commonarchivecore.internal.exception.SaveFailureException: Meta-INF/application.xml

Needless to say, there are no two applications in the ear file XML file, so I can't explain the "duplicate entry" error Is this exception familiar to anyone? How?

Solution

My suggestion is to use 7-Zip to open / explore the ear and ensure that there are no two applications at the meta-inf level XML file Zip will create duplicate entries for files under many conditions, especially if you compress source files from multiple directories together We just had the same problem
