JBoss ear isolation and spring deployer

[lorgh]

Hello.
I have a problem with spring delpoyer and isolated ear (classloading http://wiki.jboss.org/wiki/Wiki.jsp?page=ClassLoadingConfiguration ) in JBOSS.
I get this exception while getting datasources from jndi (defined in xxx-ds.xml in jboss) using JndiObjectFactoryBean:

org.springframework.beans.TypeMismatchException: Failed to convert property value of type [org.springframework.jndi.JndiObjectFactoryBean] to required type [javax.sql.DataSource] for property 'dataSource'; nested exception is java.lang.IllegalArgumentException: No matching editors or conversion strategy found])

Everything works if ear is not isolated. Any ideas how to resolve this problem?

I'm using Jboss 4.0.x and Spring 1.2.8

This is strange:

Failed to convert property value of type [org.springframework.jndi.JndiObjectFactoryBean] to required type [javax.sql.DataSource]

How does it convert this when in non-isolated env?

In not isolated env it works fine - i use it with hibernate which requires javax.sql.DataSource so looks like it is converted ok.

I have this definition:

<bean id="dataSource1"
 class="org.springframework.jndi.JndiObjectFactoryBean">
 <property name="jndiName">
 <value>java:datasourceFromJboss</value>
 </property>
</bean>

In JBoss there is 'local-tx-datasource' entry.

Read from wiki.
Your problem is a classical isolation problem.

Is there a classic Isolation solution? I am seeing the same thing.

The classical solution: As it turns out reading every piece of JBoss documentation about ClassLoaders, EAR files, isolation and such is a classic way to learn and to solve problems. My problems ended up being a small typo in an ivy file that caused me to get the wrong version of a library. This was pointed out to me by a coworker while I had a big red face! Anyway...

One thing that is informative is the URLs section in the deployed ear which tells you what libraries you have loaded in the ear.

Here is a classic read:
