can any one help. I want to check with the community before raising a bug.
I have used callisto and Ganymede m4 and had the same error in both.
I aam trying to build some simple applications with jboss and ejb3.
I keep getting anonomlies in the eclipse wtp j2ee editor context that seem
fairly consistent for me and a little annoying in use.
1. A number of times when I create an EJB project and specify the
peristence facet - the project gets created but the builder reports an
error on any persistence file i edit and save
example ..
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
<persistence-unit name="embedDS" transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider >
<jta-data-source>jdbc/embedDS</jta-data-source>
<properties>
<property name="hibernate.hbm2ddl.auto" value="create-drop"/>
<property name="hibernate.show_sql" value="true"/>
</properties>
</persistence-unit>
</persistence>
this persistence file shows an error in eclipse at the first line saying
"Invalid content [no root node]". whatever i do edit/overwrite save it
says the same. However if i deploy the project to the jboss server it
works and the persistence context can be used just fine -
this happens in both callisto and ganymede.
2. when i deploy an EAR project to jboss and use the add/remove projects
action on the server - I keep geting errors in the deploy which say that
the META-INF/application xml is not there. It still uninstalls and
reintalls. but i get this error.
I have the jboss tools bundle installed on my callisto build - and it
seems to use exploded EAR format (directory structure is deployed in the
'deploy' directory but the META-INF directory doesnt have an
application.xml file (hence the error) but it is there in the eclipse
project directory in the EAR project.
When i tried this in Ganymede (no jboss tools deploy) its copying the .ear
file into the deploy directory - however its moaning about not finding the
embedDS data source
--- MBeans waiting for other MBeans ---
ObjectName: jboss.j2ee:service=EJB3,module=CustSiteEAOProject.jar
State: FAILED
Reason: java.lang.ClassNotFoundException: Unexpected error during load
of: org.ww.eao.CustomerEAOBean, msg=Bad version number in .class file
ObjectName: persistence.units:ear=CustSiteEar.ear,unitName=embedDS
State: FAILED
Reason: javax.persistence.PersistenceException: [PersistenceUnit:
embedDS] class or package not found
I Depend On:
jboss.jca:service=DataSourceBinding,name=jdbc/embedDS
--- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM ---
ObjectName: persistence.units:ear=CustSiteEar.ear,unitName=embedDS
State: FAILED
Reason: javax.persistence.PersistenceException: [PersistenceUnit:

I Depend On:

State: FAILED

Still trying to find out why its not started. This works fine from the
callisto build - but not right now in the ganyemede one.

Does this happen when it builder validates the file? As the normal XML
Editor validation had no problem with this file using WTP 2.0.1 and Europa.

Will, since you seem to be able to produce this pretty consistently, I'm
going to recommend that you open a bug report against the WTP JEE
component. Put as much detail in the bug report, as it will help the
committers track it down.
Especially since you are able to reproduce this on both Ganymede and
Callisto.
