Service-mix classLoader Issues when combined with shared library.
Hey Guys,
I am bit confused with Service-mix class-loaders in 4.2. Although I read
this http://servicemix.apache.org/classloaders.html
here's what I am doing:
We are using shared library and referring the shared library in Service
Units as below.
In my xbean.xml of my SU.
<classpath>
<library>eqcache</library>
</classpath>
eqcache is installed as shared library.
Now my rest of the settings in xbean.xml for Hibernate SessionFactory are as
below.
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<!-- <property name="dataSource" ref="dartDataSource"/> -->
<property name="hibernateProperties">
<props>
<prop
key="hibernate.connection.driver_class">com.mysql.jdbc.Driver</prop>
<prop
key="hibernate.connection.url">jdbc:mysql://192.168.5.511234/lic_training_20023423110
</prop>
<prop key="hibernate.connection.username">ssasdas</prop>
<prop key="hibernate.connection.password">asdasds</prop>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect
</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.bytecode.use_reflection_optimizer">true</prop>
<prop key="hibernate.use_outer_join">true</prop>
<prop key="hibernate.statement_cache.size">2000</prop>
<prop key="hibernate.max_fetch_depth">5</prop>
<prop key="hibernate.jdbc.batch_size">0</prop>
<prop key="hibernate.connection.autocommit">false</prop>
<!--
Set the release mode to auto, so that the DB connections are
released as soon as the transaction is complete.
-->
<prop key="hibernate.connection.release_mode">auto</prop>
</props>
</property>
<property name="lobHandler" ref="defaultLobHandler" />
</bean>
In the above properties when I deploy my SU notice the driver class in bold.
I get the error
java.sql.SQLException: No suitable driver found for
jdbc:mysql://192.168.5.51/lic_training_200110
I tried Changing a few things and I came to know Classloader is unable to
load driver class and it searches for driver class in eqcache which is my
shared library and if I add driver dependency in my shared library
everything works not sure why though??

The classloader will search classes in that sharedlib, so I guess
that's more similar as "we are just including the shared library in the
class path" from your words.

If you put your driver lib as another items of <classpath>...</
classpath>, I believe the classloader will also search classes from it.

Hey Freeman,
Thanks for the reply but I am a bit confused now.
I am facing the exact same Problem in 3.4 fuse. Just want to make sure while
setting the classpath to shared library are we setting the actual class path
to the shared library or we are just including the shared library in the
class path.
Cause currently what is happening his my class loader searches everything in
shared library.
Thanks,
Aditya

Ok, did you see the "New in Servicemix 4.2.0" part from [1], from
this way, you can refer mysql driver bundle in your SU.
In GSGi world generally you must specify which outside package is
available for your own bundle, and the classloader used for your own
bundle won't search all classes in OSGi evnironment.

Hey freeman,
Sorry I didn't gave the complete INFO:
I am shipping my old services(JBI Service Assemblies that worked in 3.3) in
4.2 so yeah they include no Import as I am not deploying them as OSGI
bundles rather I am deploying them as old zips of 3.3.
Thanks,
Aditya

Hi,
A quick question, did your su bundle import-package com.mysql.jdbc?
