[jira] [Commented] (WSS-282) STRTransform JCE provider throws
java.lang.ClassCastException: org.jcp.xml.dsig.internal.dom.DOMSubTreeData
incompatible with javax.xml.crypto.OctetStreamData in Websphere

Do the fixes applied to the attached jar fix this issue? Or is further work required?

> Key: WSS-282
> URL: https://issues.apache.org/jira/browse/WSS-282
> Project: WSS4J
> Issue Type: Bug
> Components: WSS4J Core
> Affects Versions: 1.6
> Environment: WebSphere 7.0.0.15
> Reporter: Jeremy Tadman
> Assignee: Colm O hEigeartaigh
> Fix For: 1.6.1

> When using WSS4J to generate signed sender-vouches SAML tokens involving an STRTransform I get the below exception (right at the end). It only happens when there are multiple applications using WSS4J or the application is restarted.
> Seems to be related to the fact that the STRTransformProvider is added to WebSphere's JCE provider list using Security.addProvider(provider) but is loaded using the WAR module's classloader. When an app is restarted, this classloader hangs around and causes issues because org.jcp.xml.dsig.internal.dom.DOMSubTreeData loaded by the new module instance's classloader is not considered an instance of the org.jcp.xml.dsig.internal.dom.DOMSubTreeData class loaded by the STRTransform instance. I tested this by modifying the source code and printing out which classloader had loaded the class. In the case where things work (first startup of the first application to use WSS4J) the classloaders are the same. In cases where things don't work the classloader of the DOMSubTreeData instance passed into the transform is different to the classloader of the DOMSubTreeData class itself. Similar result when trying from one application then another.
> This seems loosely related to https://issues.apache.org/jira/browse/WSS-82 and http://bouncy-castle.1462172.n4.nabble.com/Bug-in-Cipher-class-td1465452.html.
> Seems there are problems running custom JCE providers on WebSphere (and IBM say they don't support custom JCE providers).
> Adding WSS4j to a higher level classloader causes all kinds of other errors to come up.
> Is there any way we can get this to work or are we WebSphere users out of luck? (Or am I just doing something horrible wrong?). I've already applied the fixes shown in https://issues.apache.org/jira/browse/WSS-273 (I got those errors before I got this one).
