Call of a jar-file (compiled with matlab), throw complete stack (of matlab errors) back to java

Hallo,

I'm trying to integrate a compiled matlab-programm (as a jar-file) into a java-environment.

1) Is it possible to get a complete stack-trace back to original calling jar-file out of matlab? (Line numbers, functions, ...)

Up to now, it seems that I've to use something like that:

try

catch
msgText = getReport(ME,'extended','hyperlinks','off');
msgText2 = regexprep(msgText,'\s+',' ');
baseException = MException(msgID,msgText2);
throw(baseException);
end

2) Is it possible that the all exceptions are formated in that way, without defining a try-catch-block around the whole function?

Thank you

1.The message text and stack information would be available in an 'MWException' class in Java. You can use a try/catch on the java side to capture the same. Refer the following example:

    try{
      foo.Class1 c = new foo.Class1();
      c.foo();
    }
    catch(MWException e){
      System.out.println(e.getMessage());
      e.printStackTrace();
    }

2. Since MWExceptions don’t include the message id, you can write a small function to capture the desired information rather than include it in each try catch.

Thank you for the hint, I'll use that.
