Hi every body:

I’m using myeclipse version 6.0.0 to build may java applications, I was using myeclipse 5.5 so far and everything worked fine, now I upgrade to version 6.0.0 I’m getting some errors before didn’t happen:

When I create an application with struts 1.2 and hibernate 3.1 capabilities to make a simple insertion in a database table using a form after deploy it I get this error:

%%%% Error Creating SessionFactory %%%%
java.lang.SecurityException: class "org.apache.commons.collections.SequencedHashMap"'s signer information does not match signer information of other classes in the same package

However when I test if the insert work with a main method using the Dao Classes that myeclipse generates I not get any error and the insert in the database is made succesfully.

I supposed this is a bug of myeclipse, is there any way to solve this problem, could you help me please to fix that ???
Thanks in advanced.

Apply the 6.0.1 update to your installation. That should fix this issue.
