Jasperserver Web Services call to runReport - What libraries?

Hi all,

I'm using iReport and JasperServer Pro 4.7, and am wanting to call the runReport method on WSClient in a Java servlet.

The problem I'm having, is locating the required JARs/Libaries to run the following piece of code:

      JServer js = new JServer();
      js.setUrl(serverUrl);
      js.setUsername(serverUser);
      js.setPassword(serverPassword);

      ResourceDescriptor rd = new ResourceDescriptor();
      rd.setWsType(ResourceDescriptor.TYPE_JRXML);
      rd.setUriString("/Projects/Report1");

      Map params = new HashMap();
      params.put("param1", "1234");

      WSClient client = new WSClient(js);
      JasperPrint jasperPrint = client.runReport(rd, params);

I've attached the following libraries to my Java application:

com-jaspersoft-ireport-jasperserver.jar
js_activation-1.1.jar
js_axis-1.4patched.jar
js_commons-codec-1.3.jar
js_commons-discovery-0.2.jar
js_commons-httpclient-3.1.jar
js_jasperserver-common-ws-3.5.0.jar
js_jaxrpc.jar
js_mail-1.4.jar
js_saaj-api-1.3.jar
js_wsdl4j-1.5.1.jar

What library do I need to use the JasperPrint object? I've tried using jasperreports-4.7.jar, however at runtime, I'm getting dependency exceptions for "java.lang.NoClassDefFoundError: com/jaspersoft/ireport/designer/IReportManager"

The Web Services documentation is very thin on details.

Any help would be great.

Cheers,
Chris
