I am attempting to write a stand-alone JUnit test to invoke and validate a web
service I have running in JBoss 4.0.4GA (JDK 5). According to
http://labs.jboss.com/portal/jbossws/user-guide/en/html/clients.html all I need
to do is use this:
public void testEchoString() throws Exception
| {
| ServiceFactoryImpl factory = new ServiceFactoryImpl();
| Service service = factory.createService(new
QName("ANY_SERVICE_NAME"));
|
| Call call = service.createCall();
| call.setOperationName(new QName(TARGET_NAMESPACE, "echoString"));
| call.addParameter("String_1", Constants.TYPE_LITERAL_STRING,
ParameterMode.IN);
| call.addParameter("String_2", Constants.TYPE_LITERAL_STRING,
ParameterMode.IN);
| call.setReturnType(Constants.TYPE_LITERAL_STRING);
|
| call.setTargetEndpointAddress(TARGET_ENDPOINT_ADDRESS);
|
| String hello = "Hello";
| String world = "world!";
| Object retObj = call.invoke(new Object[]{hello, world});
| assertEquals(hello + world, retObj);
| }
However, the "echoString" service takes simple String objects as input and my
service takes a custom object. I have tried modifying the code to use my
object but I am getting an exception. Here is my code:
| public void testEchoString() throws Exception {
| ServiceFactoryImpl factory = new ServiceFactoryImpl();
| Service service = factory.createService(new QName("JBossTest2"));
|
| Call call = service.createCall();
| call.setOperationName(new
QName("http://us.mycompany.com/jbosstest2/1.0";, "prescreen"));
| call.addParameter("JBossTest2Request", new
QName("JBossTest2Request"), ParameterMode.IN);
| call.setReturnType(new
QName("com.mycompany.us.test.JBossTest2Reply"));
|
|
call.setTargetEndpointAddress("http://jbertr1005:8080/jbosstest2/1.0";);
|
| String hello = "Hello";
| String world = "world!";
| Object retObj = call.invoke(new Object[] { new JBossTest2Request()
});
| assertEquals(hello + world, retObj);
| }
|
And here is the exception I am receiving:

How do I get a simple DII client to invoke a web service that uses custom
objects for input and output?
