I am unable to pass a parameter using SOAP::Lite to call a Java web service. My java WS wsdl is as below. This is a simple web service tat takes two number as input parameters adds them and returns a result. Here is my wsdl -------------------------------------------------------------------------------------------------- <code> <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <!-- Generated by JAX-WS RI at http://jax-ws.dev.java.net.

Here is my call. my $soap = SOAP::Lite->uri("http://ecf/")->proxy("http://localhost:8080/WAPP1/TWS"); print "Output ----> " . $soap->addnumbers(10,20) . " \n" ; I get the output as zero. I tried to check the parameters received by the java web service. It is zero for both the parameters. I even tried using SOAP::Data->new(name => 'a', value => 10) but to no avail. When I use Java as the client, everything is fine. Any help would be greatly appreciated. Thanks
