Develop and compiling my own Mbnode is OK - BUT RUNNING FAILS

Hello !

Platform: WSAD 5.1 java 1.4
Platform: MBtoolkit java 1.4

I'm developing my own MbNode from the typecal sample like

public class WorkflowEmulatorNode extends MbNode implements MbNodeInterface{
...... etc code shown in the bottom
}

I can build the project i WSAD without errors, but running the code
not successfully

NB! I have placed jplugin.jar i classpath etc.

I can't see the WorkflowEmulatorNode.class file any place in the project

Running the sample code in the MB toolkit environment fails too.

Platform: WSAD 5.1 java 1.4

java.lang.NoClassDefFoundError: com/ibm/broker/trace/Trace
at com.ibm.broker.plugin.MbNode.<init>(MbNode.java:76)
at WorkflowEmulatorNode.<init>(WorkflowEmulatorNode.java:6)
at WorkflowEmulatorNode.main(WorkflowEmulatorNode.java:64)
Exception in thread "main"


If You have any suggestions to what goes wrong please give
answer this question.



regards Tom Stevns Nielsen


Code shown below
*************************************************************************
import com.ibm.broker.plugin.*;

public class WorkflowEmulatorNode extends MbNode implements MbNodeInterface{
private String _attribute1, _attribute2;

public WorkflowEmulatorNode() throws MbException {
// create terminals here
createInputTerminal("in");
createOutputTerminal("out");
createOutputTerminal("failure");
}

public void evaluate(MbMessageAssembly assembly, MbInputTerminal in)
throws MbException
{
// do node processing here
// ...

// all nodes (except output nodes) should propagate a message assembly
// to the next node in the message flow via an output terminal.
MbOutputTerminal out = getOutputTerminal("out");
if(out != null)
out.propagate(assembly);
}

// the following static method declares the name of this node to the broker
public static String getNodeName()
{
return "ComIspSampleNode";
}

// by supplying the following two methods, the broker infers this node
// has an attribute named 'firstAttribute'.
public String getFirstAttribute()
{
return _attribute1;
}

public void setFirstAttribute(String attr)
{
_attribute1 = attr;
}

// by supplying the following two methods, the broker infers this node
// has an attribute named 'secondAttribute'.
public String getSecondAttribute()
{
return _attribute2;
}

public void setSecondAttribute(String attr)
{
_attribute2 = attr;
}

public void onDelete( )
{
// perform node clean up if necessary.
}
public static void main(String[] args) {

try {

WorkflowEmulatorNode wfen = new WorkflowEmulatorNode();
wfen.createInputTerminal("MyInput");
wfen.createOutputTerminal("MyOutput");
} catch (MbException e) {
// TODO: handle exception
}

}


}

In the meanwhile I have imported bipbroker.jar . It eliminates the

java.lang.NoClassDefFoundError: com/ibm/broker/trace/Trace

but afterwards another arises like:

java.lang.UnsatisfiedLinkError: _createInputTerminal
at com.ibm.broker.plugin.MbNode._createInputTerminal(Native Method)
at com.ibm.broker.plugin.MbNode.createInputTerminal(MbNode.java:137)
at WorkflowEmulatorNode.<init>(WorkflowEmulatorNode.java:8)
at WorkflowEmulatorNode.main(WorkflowEmulatorNode.java:64)
Exception in thread "main"


Very funny indeed ;o))
