Hi there, I wrote the following class, which will invoke a workflow process. I use this from a servlet which takes normal xml over http (not soap) and then calls the process with the parameters. | /** | * | */ | public class WFProcessFactory { | | JbpmConfiguration jbpmConfig = null; | | /** | * | * @param processId | * @param processName | * @param key | * @param processVariables | * @param signalStart | * @return | */ | public long startProcess(long processId, String processName, String key, HashMap processVariables, boolean signalStart) { | long tokenId = 0; | | if (jbpmConfig == null) { | jbpmConfig = JbpmConfiguration.getInstance(); | } | JbpmContext jbpmContext = jbpmConfig.createJbpmContext(); | try { | // get the session and process definition according to the process id | GraphSession graphSession = jbpmContext.getGraphSession(); | | ProcessDefinition processDefinition = null; | if (processName.length() > 0) { | processDefinition = graphSession.findLatestProcessDefinition(processName); | } else { | processDefinition = graphSession.getProcessDefinition(processId); | } | | // if there are no process variables, then create an empty variable list | if (processVariables == null) { | processVariables = new HashMap(); | } | // startup the process, set its business key (for correlation purposes, and | // signal it to start going with the flow | ProcessInstance processInstance = processDefinition.createProcessInstance(processVariables); | | processInstance.setKey(key); | tokenId = processInstance.getRootToken().getId(); | if (signalStart) { | processInstance.signal(); | } | } finally { | jbpmContext.close(); | } | return tokenId; | } | } | The XML that I post to my servlet looks something like this. | Input: | | <launch_workflow> | <process_id>401</process_id> OPTIONAL if process_name is specified | <process_name>SomeProcessName</process_name> OPTIONAL if process_id is specified | <process_key>401_00001</process_key> | <process_input> | <process_var> | <var_name>item1</var_name> | <var_value>value1</var_value> | </process_var> | <process_var> | <var_name>item2</var_name> | <var_value>value2</var_value> | </process_var> | <process_var> | <var_name>item3</var_name> | <var_value>value3</var_value> | </process_var> | <process_var> | <var_name>item4</var_name> | <var_value>value4</var_value> | </process_var> | </process_input> | </launch_workflow> | | | Output: | | <launch_result> | <token_id>499</token_id> | </launch_result> | One thing to take note of: Don't re-instantiate the JBPMConfiguration object with each call, as this causes the server to run out of memory really quickly. I hope that this helps. Regards View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4163014#...
