Hi Guru,
With the help from spring integration community, I can successfully deploy
spring beans using deployer release 2.5 (jdk5) in JBoss 4.2.2GA and I can also
access the deployed beans from another web application.
However I am running into a problem of using ClassLoader inside the deployed
spring beans.
>From my web application, I can get bean reference called "billingBean".
>However when I invoke one method of this bean, which will dynamically create
>some instances using classloader, I got "java.lang.ClassNotFoundException",
>and the stacktrace is as below:

The not-found-class,
com.iseemedia.provisioningbilling.actionflow.action.AddSubscriptionAction
actually is inside the spring archive file. I also tried to copy the spring
archive file to default/lib (of course, I renamed it as *.jar), I still got
same exception.
Here is the snapshot of my code that will dynamically create some instances.
This piece of code worked fine before using the spring deployer.
| HashMap<String, Action> aMap = new HashMap<String, Action>();
| for (String key : flowDef.getActionMap().keySet())
| {
| ActionDef aDef = flowDef.getActionMap().get(key);
|
| Action a =
(Action)ClassLoader.getSystemClassLoader().loadClass(aDef.getType()).newInstance();
| aMap.put(key, a);
| }
|
The bold line is the actual cause of the exception. I just wonder which class
loader I should use inside a deployed bean?
Thanks in advance,
Ivan Yuan
