Unfortunately, this capability does not appear to support interfaces that return or pass objects that are not primitive equivalents (e.g. Long). i.e. it will only convert to standard xsd types from a range of java objects it accepts as equivalents.

Hi Lucas…The example you posted above works but I am worrried that if I change argument parameters to classType with a DTO(with 2 attributes) then the application fails at runtime. Also, somewhere you have mentioned that you also tried the same but was not successful. So, is it possible to invoke such kind of EJB method?

Hello, I followed the case closely (with the same name of classes, methods, etc),Â but still get the error: â€œCould not convert from java interface to interface type wsdl.Exception=nl.amis.calculator.Calculatorâ€. I created a Java class to test the lookup and function correctly. However, when I try to wire a Mediator to this Reference, I run into an Interface Conversion Error. I’ve included the line javaInterface = “nl.amis.calculator.Calculator” in file composite.xml, but still get error. Can anyone help me?

Great post. This is exactly what I’m trying to achieve. Unfortunately without success so far, even with a simple dummy EJB and adding the javaInterface attribute in composite.xml I’m still getting “Could not convert from java interface to interface type wsdl”.
Any ideas?
Could you be so kind to share your projects? Then I could investigate if it’s simply a project or an environment issue.
Thanks a lot
Markus
