hi i created an instance of token and trying to signal the process with the newly created
token. here im not using the root token for signalling. so im trying to save the data in
the tables and im getting the token id of the root token as 500 and the token which i
created has the token id 0. and its throwing the error hibernate transient object
exception. can any one just help me out
here is the code
package com.westpac.nzlo.tempjbpm;
import java.io.BufferedReader;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStreamReader;
import org.jbpm.JbpmConfiguration;
import org.jbpm.JbpmContext;
import org.jbpm.graph.exe.ProcessInstance;
import org.jbpm.graph.exe.Token;
public class CreateDuplicateToken {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
JbpmConfiguration jbpmConfiguration = null;
JbpmContext jbpmContext = null;
try {
jbpmConfiguration = JbpmConfiguration.parseInputStream(new
FileInputStream("src/config.files/jbpm.cfg.xml"));
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
jbpmContext = jbpmConfiguration.createJbpmContext();
System.out.println("Create Duplicate Token:");
System.out.print("Enter the ProcessInstance ID: ");
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
long processInstanceID = 0 ;
try {
processInstanceID = Long.parseLong(br.readLine());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
ProcessInstance processInstance =
jbpmContext.loadProcessInstanceForUpdate(processInstanceID);
Token rootToken = processInstance.getRootToken();
Token duplicateToken = new Token();
duplicateToken.setNode(rootToken.getNode());
System.out.println("Root TokenID: "+rootToken.getId());
System.out.println("Duplicate TokenID: "+duplicateToken.getId());
System.out.println("ProcessInstance of Duplicate:
"+duplicateToken.getProcessInstance().getId());
System.out.println("Parent of Duplicate: "+duplicateToken.getParent().getId());
jbpmContext.save(duplicateToken);
duplicateToken.signal();
jbpmContext.save(duplicateToken);
jbpmContext.close();
}
}
here is the exception
