3rd party ClassLoader

Hi,
If you want to use third party libs inside your service, you just need
to create a directly called "lib" inside your service and add all your
jar files into it. Then Axis2 will do the right thing. So with this the
structure of the aar would be like following;

MyService.aar
META-INF
services.xml
lib
lib1.jar
lib2.jar


Thanks,
Deepal

classloader is an attribute of service you are creating as seen here

package org.apache.axis2.spring.SpringServiceTest {
setup() or main() method
        AxisService service =
                createSpringService(springServiceName, new RawXMLINOutMessageReceiver(),
                                    "org.apache.axis2.extensions.spring.receivers.SpringAppContextAwareObjectSupplier",
                                    "springAwareService",
                                    springOperationName);
        createSpringAppCtx(service.getClassLoader());
        UtilServer.deployService(service);

public void createSpringAppCtx(ClassLoader cl) throws Exception {
        ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext(
                new String[] { "/spring/applicationContext.xml" }, false);
        ctx.setClassLoader(cl);
        ctx.refresh();
    }
</snip>

Thanks for the replies.

Here's where we've placed our code.

\webapps\axis2\WEB-INF\services\TestService.aar
\webapps\axis2\WEB-INF\lib\TestBusiness.jar

The TestService web service calls a business class in the
TestBusiness.jar.  This works properly when the classes are left
unencrypted.

Once we encrypt the classes in these two files (*.class becomes
*.classx), the standard ClassLoaders are unable to find the classes.  

In regular Tomcat WebApps we can configure the context to use a custom
WebAppClassLoader which knows to look for the *.classx files and decrypt
them before loading them.  Modifying \webapps\axis2\META-INF\context.xml
did not have the same affect in axis2 as it did in regular webapps.

<Context>
        <Loader loaderClass="com.CustomWebAppClassLoader"
        useSystemClassLoaderAsParent="false" />
</Context>

-----------------------------

Regarding creating a service.  I've seen this mentioned in a few places,
but don't understand.  Where would I put code that created a service.
You can't put code that creates your service in your service.  Although
I suppose you could spawn another service.

I feel like I'm missing something simple.

Thank you.
