Migrating jboss-beans.xml to Wildfly - problems.

Paul Keogh Apr 8, 2014 6:38 AM

Hi,

I am having a problem migrating an application from JBoss 5 to Wildfly.

First problem I see in the AS trace is;

10:55:51,424 INFO [org.jboss.as.pojo] (MSC service thread 1-1) JBAS017000: Found legacy bean/pojo namespace: urn:jboss:bean-deployer:2.0 - might be missing some xml features (potential exceptions).

followed quickly by;

Caused by: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[27,3]

Message: JBAS014788: Unexpected attribute 'factoryClass' encountered

when it tries to parse my jboss-beans.xml file.

My questions are;

What should be the namespace be ?

How can I resolve the unexpected attribute error ?

Thanks,

I'm actually rather surprised we don't have support for factoryClass. Can you please file an Enhancement at https://issues.jboss.org/browse/WFLY in the "POJO" component?

How does your xml look like?

We do have support for "factory-class" in constructor element.

Hmmm, I see, we used to have "factoryClass". Dunno why I renamed it to "factory-class" ...
* http://anonsvn.jboss.org/repos/jbossas/projects/kernel/trunk/kernel/src/main/resources/schema/jboss-beans-common_2_0.xsd

Should be easy to add back the legacy support.
Meanwhile change it to "factory-class".

Note: same change is made to factoryMethod --> factory-method

Thanks all for your help - that got me over that problem.

Now I see;

Caused by: org.jboss.as.server.deployment.DeploymentUnitProcessingException: JBAS017082: Exception while parsing POJO descriptor file: "/home/paul/development/wildfly-8.0.0.Final/standalone/deployments/mobicents-ss7-service.sar/META-INF/jboss-beans.xml"

The </annotation> tag is on line 216.

Is the annotation tag supported ?

No.

That would require all/most of the legacy MDR / AOP project to be somehow migrated.
Which is far beyond plain POJO support.

OK thanks.

Can you point me at a link that describes a migration/rewrite approach ?

There is no general migration approach.

We had a project MDR (Meta Data Repository), which we used to look at the metadata for any service.
So, basically we were able to have different metadata per instance.

In this case the metadata was annotation for that bean instance.
And in most cases annotation triggered some AOP invocation.
In this case it was a JMX registry.

Hence migration here would be to manually register bean as mbean.
