How to generate soap request xml from wsdl file in java

Question

I am looking for some java opensource api for generating soap request xml file by passing wsdl_URL and operation name as parameters. Actually soapUI is doing this and I tried to go through the soapUI source code, but I am not able to understand the whole code to get my task done.

Is there any java api available to do this (apache or something)?

I spent couple of days in the net and didn't see any result.

If any body has any idea please help me.

Thanks in advance.

You can use the open-source Membrane SOA library ([http://www.membrane-soa.org/soa-model-doc/1.4/java-api/create-soap-request-template.htm ]) to generate XMLs for each operation defined in the WSDL:

public void createTemplates(String url){

    WSDLParser parser = new WSDLParser();
    Definitions wsdl = parser.parse(url);   
    StringWriter writer = new StringWriter();
    SOARequestCreator creator = new SOARequestCreator();
    creator.setBuilder(new MarkupBuilder(writer));
    creator.setDefinitions(wsdl);

    for (Service service : wsdl.getServices()) {
        for (Port port : service.getPorts()) {
            Binding binding = port.getBinding();
            PortType portType = binding.getPortType();
            for (Operation op : portType.getOperations()) {
                creator.setCreator(new RequestTemplateCreator());
                creator.createRequest(port.getName(), op.getName(), binding.getName());
                System.out.println(writer);
                writer.getBuffer().setLength(0);
        }
    }
}

Soap UI also provide Java Api for creating request and response xml from WSDL.

 public static void main(String[] args) throws Exception {
        WsdlProject project = new WsdlProject();
        WsdlInterface[] wsdls = WsdlImporter.importWsdl(project, "http://localhost:8080/Service?wsdl");
        WsdlInterface wsdl = wsdls[0];
        for (Operation operation : wsdl.getOperationList()) {
            WsdlOperation wsdlOperation = (WsdlOperation) operation;
            System.out.println("Request:\n"+wsdlOperation.createRequest(true));
            System.out.println("\nResponse:\n"+wsdlOperation.createResponse(true));

        }
    }

Developer's corner of Soap UI has nice pointers for integrating with soap UI Api.
