Could not read entries java.util.zip.ZipException: error in opening zip file

Question

I'm having problems migrating from jboss 4.2.1 to jboss 5.1.0

This is the exception i got when I try to deploy my .ear file

    WARN  [Scanner] could not read entries
java.util.zip.ZipException: error in opening zip file
    at java.util.zip.ZipFile.open(Native Method)

    at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:3910)
    at org.apache.catalina.core.StandardContext.start(StandardContext.java:4393)

and so the error is larger than that.

It says is a WARN but it doesn't unzip the .ear/.war files and of course it doesn't deploy anything.

I've checked the file isn't corrupt. Any help would be apreciated. Thanks & cheers

Answer 1

This is caused by spring's context:component-scan feature incompatibility with JBoss5 Virtual File System (VFS). There's a lib (called snowdrop, provided by JBoss) you can drop into the project that contains a VFS-enabled application context implementation.

You can find it here - http://www.jboss.org/snowdrop

Answer 2

Problem solved. It was a couple of libraries out of date of the seam framework. Apparently they changed some things from seam version for jboss4 to jboss5.

Just update seam libraries and thats all.

Thanks everybody for your interest. Hope my solution helps others Cheers
