problems with JiBX and DM

Hi all!

I have a problem using JiBX within Spring DM. I have a jibx runtime bundle and my client bundle that includes precompiled jibx classes. Versions do match because I packaged jibx runtime myself using the same (latest) version as for compiling.

However at runtime I get

JiBXException: Classloader conflict for binding factory 'foo.test.JiBX_bindingFactory' - factory does not implement required interface

I checked my client bundle - the class is there, I assume that it implements everything correctly because it was generated by JiBX compiler. When I digged into jibx code I found that it tries to perform some things on such a class via reflection and in case of any exception throws its own exception with this text.

Therefore I assume that the problem is that JiBX bundle does not see my bundle classes (that is quite expected as JiBX bundle knows nothing about my client bundle - it neither imports nor requires it). So the question is - what do I do in this case? Is there anyway to share my bundle's classes with an imported one (jibx).

Or maybe my assumption is wrong - then why the hack do I get that exception? =)

I've got the sources, fired up my debugger and have now more details. This is the code fragment from org.jibx.runtime.BindingDirectory that throws this error:

Code:

---

try {
            Class factory = loader.loadClass(name);
            Method method = factory.getMethod(FACTORY_INSTMETHOD, EMPTY_ARGS);
            result = method.invoke(null, (Object[])null);
        } catch (SecurityException e) {
            ex = e;
        } catch (ClassNotFoundException e) {
            ex = e;
        } catch (NoSuchMethodException e) {
            ex = e;
        } catch (IllegalAccessException e) {
            ex = e;
        } catch (InvocationTargetException e) {
            ex = e;
            incompat = true;
        } finally {
            if (ex == null) {
                if (result instanceof IBindingFactory) {
                    // ommited
                } else {
                    throw new JiBXException
                        ("Classloader conflict for binding factory '" + name +
                        "' - factory does not implement required interface");
                }
    // ommited

---

the 'name' variable is 'foo.test.JiBX_bindingFactory' the classloader is my bundle's classloader (foo.test) so it must see this class without problems

however there is some exception thrown because after this line

Code:

---

Class factory = loader.loadClass(name);

---

execution falls directly into the finally block with ex == null and result == null. That is strange because there are a lot of exception types to be caught and it seems that this exception is not one of them.

I tried to evaluate

Code:

---

loader.loadClass(name)

---

in 'Expressions' view in STS to view the exception it gets but strangely it doesn't evaluate anything at all (even something like 2+2 - just shows blank result).

P.S. I use Virgo 2.1.1 if that is to be mentioned

=== update ===

OK, I finally found the source of problem when I faced it again. The problem is that JiBX instrumented classes are extending some classes from org.jibx.runtime.impl package which I thought was private, so I did neither export or import it. Hope that helps someone =)
