Mobicents 2.4.0.FINAL: File deployer fails to load RA DU

[prolancer]

Hi,

I have a custom RA which uses a bunch of 3rd-party jars which we
bundle in a library jar.

When I deploy the RA using the JMX console all works fine (note that
this RA deploys Ok on the Rhino (openCloud) server). I can install the
DU jar, then create an entity, change configuration, bind a link and
activate. All is good.

However, when I try and deply by placing the DU jar in the deploy
directory, the server fails to delpy the DU due to a
ClassNotFoundException for one of the calsses which is in one of the
3rd party jars.

The "missing" class is org.hsqldb.util.SqlTool and it exists in the
hsqldb-1.8.0_10.jar file which we put in the library jar for the DU.

Your help on this will be greately appreciated.

Here is an extract from the library-jar.xml (I removed the blocks for
other 3rd-party jars):

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE library-jar PUBLIC "-//Sun Microsystems, Inc.//DTD JAIN SLEE
Library 1.1//EN" "http://java.sun.com/dtd/slee-library-jar_1_1.dtd">
<library-jar>

<library>
<library-name>hspChargingClient</library-name>
<library-vendor>au.com.prolancer</library-vendor>
<library-version>1.0</library-version>

:
<jar>
<jar-name>hsqldb-1.8.0_10.jar</jar-name>

<security-permission-spec>
grant {
permission java.security.AllPermission;
};
</security-permission-spec>
</security-permissions>
</jar>
:

</library>
</library-jar>

The deployable-unit.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE deployable-unit PUBLIC "-//Sun Microsystems, Inc.//DTD JAIN
SLEE Deployable Unit 1.1//EN" "http://java.sun.com/dtd/slee-deployable-

<jar>hsp-charging-event.jar</jar>
<jar>hsp-charging-ratype.jar</jar>
<jar>hsp-charging-ra.jar</jar>
</deployable-unit>

The hsp-charging-library.jar is the library jar file which we create.
It contains the hsqldb-1.8.0_10.jar file.

Here is the log when I use the JMX console to deploy the RA DU:

Same issue in Mobicents 2.4.1.FINAL.

You are bundling HSQL in the library, this jar already exists,
probably with a different version, in JBoss AS5 shared libs. Now SLEE
has its own classloaders, which hierarchy defines the JBoss AS5 shared
classloader as the ultimate parent. Following standard classloading
relations SLEE tries to load first classes from parent, so in your
case HSQL will be loaded from JBoss AS5 instead of your library.

You have two options, replace the JBoss AS5 HSQL jar in
$JBOSS_HOME/common/lib with your own version and hope this doesn't
break anything, or use in Mobicents don't bundle the HSQL library, or
bundle a library with same version as JBoss AS5.

[prolancer]

Thank you Eduardo.

You are correct. JBoss AS already has the HSQL jar in the common lib.
Removing the jar from the library JAR (thus the DU) resolves the
problem.
