I am trying to use the hessian j2me implementation @ http://hessian.caucho.com/ using java me sdk 3.0.
http://hessian.caucho.com/doc/hessian-overview.xtp#Hessian%20Client%20for%20a%20cell-phone mentions the usage for j2me.
The application builds without any errors/warning. But, the moment the line where MicroHessianOutput is instantiated is hit, a ClassFormatError ( java.lang.Error: ClassFormatError: 56
) is thrown.
Heres the trace :
TRACE: <at java.lang.Error: ClassFormatError: 56>, startApp threw an Exception
java.lang.Error: ClassFormatError: 56
- alert.AlertDemo.showOption(), bci=26
- alert.AlertDemo.startApp(), bci=9
- javax.microedition.midlet.MIDletTunnelImpl.callStartApp(), bci=1

- com.sun.midp.main.AbstractMIDletSuiteLoader.runMIDletSuite(), bci=161
- com.sun.midp.main.AppIsolateMIDletSuiteLoader.main(), bci=26
and heres showOption():
private void showOption () throws Exception{
String url = "http://localhost/hello";
HttpConnection c = (HttpConnection) Connector.open(url);
c.setRequestMethod(HttpConnection.POST);
OutputStream os = c.openOutputStream();
MicroHessianOutput out = new MicroHessianOutput(os); //error throwing line
/*
out.startCall("hello");
InputStream is = c.openInputStream();
MicroHessianInput min = new MicroHessianInput(is);
min.startReply();
System.out.println(min.readString());
*/
}
I have jdk 1.6u16 installed. I am thinking it might be because the classes in the library might have been written for an older jdk. I don t see any option in the IDE to configure this.
Here s the class source code: MicroHessianOutput
Any idea why this could be happening ?
