Hibernate on Websphere linkage error? HELP!!

splummer · **Posted:** Tue Jan 11, 2005 2:41 pm

Howdy,

We are new hibernate users that have been working on a websphere portal application developed using the Websphere Application Developer (5.1.2). Our application works in the development environment fine, but when we deploy it to our WAS we get a linkage error in our system log that points to an error with net.sf.hibernate.xml.XMLDatabinder.getOutputStyleSheetTemplates.

We are getting kind of desperate to figure this out, any help that you can give would be very cool!

Hibernate version: 2.1.6

Name and version of the database you are using: Oracle 9.2.2

Full stack trace of any exception that occurs:

looks like some jdk .class file mismatch - maybe your WS only have jdk 1.3 libraries and you run with 1.4 in development ?

Hmm. Linkage errors. These are usually nasty ones to get to the bottom of.

What version of WAS are you using. IBM has a habit of shipping with their own 'jvm' - the version are usually aligned to that of the sun vm. What version of the vm is being used? - check the startup log.

Basically what the stack trace is saying to you is that the class javax.xml.transform.Source that hibernate is referencing has 'changed incompatibly since the compilation of the former class' (the hibernate class).

There can be a number of reasons for this.
1) You can have multiple different versions of a partcular class on your classpath and an incompatible one is loaded first.
2) The classes are just incompatible. Are your jdks in dev/prod comparable?
3) The class that you are referencing is corrupt. Rare.

I would do the following:

Examine your classpath in detail. You can get this from the log file when ws starts up. I seem to remember ws having a main classpath and and an endorsed class path. You will need to check this out. Go through each jar file and establish where the class resides. Don't stop when you find the class - you are looking for duplicates. Be aware that Hibernate ships with the class in the xml-api.jar in the libraries directory.

Now that you have the class (or classes - each in their own jar), you need to establish which one is the culprit. (if you have more than one). It may be worth your while to do the next step even if you found only a single copy of the class, just to confirm that you are on the right track.

For each jar containing the class:
Take the jar that contains the class, and using this jar (making sure that you are running with only one copy of the class in your classpath again), run a standalong hibernate app - you should just need to build a session factory using xml mappings - as this code uses the XMLDatabinder class. The culprit class should break the app in a similar manner to what you have seen.

Now you need to remove the offending class from ws and replace it with one that is compatible with hibernate. This may be tricky as there may be dependencies from the other (ws) side. Try replacing the whole jar with one that is compatible with hibernate. Let us know how you get on.

There are other options (recompiling etc) but these are 'last resorts'
