Hello, I try to call a webservice with the signatur: public int addzwo(int a, int b, int c); and get the following exception, java.lang.NumberFormatException: For input string: "" I tried it with a webservice that accepts strings as Parameters @WebMethod | public String concat(String a, String b) | { return a+b; } This works. If I look at the SOAP Call I can see, that the int Parameters are coded as href and then referenced with a multiref Tag. What do I have to tell the webservice (EJB3 style) that it unterstands this kind of int parameters.
