Hello,
I have an extended HessianServlet which exposes a method
Public String hello()
The following client works fine. (HessianProxyFactory J2SE)
public class HessianClient {
public static void main(String[] args) throws Exception {
String url = "http://localhost:8988/HessianServer1/remoteservice";;
HessianProxyFactory factory = new HessianProxyFactory();
HelloInterface helloInterface =
(HelloInterface)(factory.create(HelloInterface.class, url));
System.out.println(helloInterface.hello());
}
This client refuses to work. (Hessian micro edition classes J2ME or
(J2SE+JSR 197) )
public class TestClass
{
private static String url =
"http://localhost:8988/HessianServer1/remoteservice";;
public static void main(String[] args) throws Exception
{
HttpConnection conn;
OutputStream os = null;
InputStream is = null;
try
{
try
{
conn = (HttpConnection)Connector.open(url);
conn.setRequestMethod(HttpConnection.POST);
os = conn.openOutputStream();
MicroHessianOutput out = new MicroHessianOutput(os);
out.startCall("hello");
out.completeCall();
os.flush();
is = conn.openInputStream(); // FAILS HERE
MicroHessianInput in = new MicroHessianInput(is);
in.startReply();
String hello = in.readString();
in.completeReply();
System.out.println(hello);
}
finally
{
if (os != null)
{
os.close();
}
if (is != null)
{
is.close();
}
}
}
catch (IOException e)
{
throw(e);
}
}
}
In this test class it falls over when it tries to open the input stream
as indicated by // FAILS HERE
The complete error message I get for J2SE+JSR197 (Hessian 3.1.3)

Any ideas how I can solve this? My remote methods were far more
complicated but because I was having problems I have gone back to the
basics and I am virtually copying a tutorial given on the Caucho web
site. I've seen posts where this all works so I don't understand why it
will not work for me!! I am obviously missing something??
Best Regards
Paul
