Since I got your kind help weeks ago, I ha= ve been working on the project and it seems there is another problem aris= e when I come into the setVariableValue() methods which are defined into = the o:xml. =20 In the example you provided, the method "plus" just read the values and= sum them together, it is mainly a "read" process, however, we also need = "write" process in the project, which means, the defined method setVariab= leValue() should be able to reconfigure the values of the variables whene= ver needed. As we know, Java could "read" and "write" xml files via DOM = tree, but I don't know how o:xml achieve this goal and couldn't find an e= xample of it from all the currently available documents. I sincerely hope= you can help me out. I appreciate your help very much always. =20 Looking forward to hearing from you. =20 Kind regards, Francisco=20 =20 =20 =20 =20 Martin Klang <[email protected]> wrote: Francisco, You need to match the function name and signature, in the same way as=20 when you call Class.getMethod(String, Class[]) in Java.
