Hi
i created an instance of token and trying to signal the process with the newly created
token here i associated the newly created token with the process instance. here im not
using the root token for signalling. so im trying to save the data in the tables.when i
tried to get the root token id it gave as 408 and the token id of the newly created token
as 0. is this procedure correct. can ny body help me out
here is the code
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.setProcessInstance(procesInstance);
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());
jbpmContext.save(duplicateToken);
duplicateToken.signal();
jbpmContext.save(duplicateToken);
jbpmContext.close();
}
}
here is the exception
