When I write a client of this class, nothing comes from Web service.
+++ nothing ? an exception or empty String ? You can use Jakarta Log4J logging lib. and debug your programm. Maris When I instanciate a Web Service class as tipical class there is no problem. I have result. Also i made a simple servlet to test jdbc drivers of application server , thereis no problem again. Does anyone have idea what can I do ?? Thank you in advance ! Best regards Tereza
