Works until jar'ed up!

My Stuff works great until I .jar it up, then there is an error "entity class not found"
The full message is

Code:

com.thomson.west.foundations.daos.HibernateUtil Initial SessionFactory creation failed.entity class not found: com.thomson.west.foundations.traudit.TrAuditValueVO

But as I said, if the classes are not jar'ed up then there is not a problem

Any assistence would be greatly appreciated!

That sounds like some sort of classpath issue or a problem with your JAR file.

Does running

Code:

jar -tvf <<jarfilename>>

produce sensible results?

if so, try starting java with the -verbose:class option - that can be helpful in tracking this kind of thing down too.

Tried the jar -tvf <<jarfilename>> and sent the output to a file. The class which is listed as not found is in the output file as well as the .hbm.xml associated with the class.

Odd part is that the other classes referenced via .addClass() calls can be found and they are all in the same jar file.

I'm thinking either there is an issue with the .hbm for this class:

Code:

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping schema="j3_foundations_dba" package="com.thomson.west.foundations.traudit" default-cascade="all">
    <class name="TrAuditValueVO" table="tracked_value">
        <id name="valueId" column="value_id" unsaved-value="null" type="long">
      <generator class="increment"/>
        </id>
        <property name="eventId" type="long" column="event_id" not-null="true"/>
        <property name="preferedTypeId" type="integer" column="perf_type_id" not-null="true"/> 
        <property name="valueName" type="string" column="value_name" not-null="false"/>
        <property name="numericValue" type="big_decimal" column="numeric_value"/>
        <property name="stringValue" type="string" column="str_value" not-null="false"/>
        <property name="dateValue" type="calendar" column="datetime_value" not-null="false"/>
        <property name="booleanValueC" type="character" column="boolean_value" not-null="false"/>
        <property name="isInterestedValueC" type="character" column="interested_value" not-null="false" />
        <property name="isClobC" type="character" column="is_clob" not-null="false"/> 
   
     <!-- Add in the mapping to the clob value -->
     <one-to-one name="clobValue" class="com.thomson.west.foundations.traudit.ClobValueVO" cascade="all" constrained="false" fetch="select"/>
   </class>
</hibernate-mapping>

Or there is an issue someplace else and this class is getting blamed for the issue.

These are SO much fun to correct.

Thanks for your suggestion!

Ok, I think I have this figured out. Issue was the use of Hibernate IN Axis2. I found the following

Quote:

I run hibernate with axis2. The structure of the aar, for example, is:

.
./META-INF
./META-INF/MANIFEST.MF
./META-INF/SWAWiseEndpoint.wsdl
./META-INF/services.xml
./com
./com/siemens
./com/siemens/swa
./com/siemens/swa/webservices
./com/siemens/swa/webservices/wisemobil
./com/siemens/swa/webservices/wisemobil/SWAWiseEndpointSkeleton.class

Where the services.xml has:

<parameter locked="false"
name="ServiceClass">com.siemens.swa.webservices.wisemobil.SWAWiseEndpointSkeleton</parameter>

So every other class reference - hibernate, spring, business logic classes
etc, are either referenced in WEB-INF/lib or WEB-INF/classes . Your hibernate
or spring config files belong at the root of WEB-INF . AFAIK nothing else is
currently supported. While an AAR has its own classloader, things like spring
and perhaps hibernate use the 'context classloader' (CCL) which is not
currently supported in an AAR.

Its as simple as that. AFAIK you can place any jar in the AAR lib directory,
provided it doesn't use the CCL. The CCL can't load service resources in an
AAR and AFAIK currently is not supported.

HTH,
Robert

So apparently if you wish to use Hibernate in Axis2 - then you don't deploy your service jar with your service.aar. You have to put them in the Axis2\WEB-INF\lib folder and your hibernate.properties seems to be picked up in the Axis2\WEB-INF\classes area.

Also note to put the hibernate.jar file in the Axis2\WEB-INF\lib folder

This is working for me (for the time being)

Hope this helps others!
