Re: {Spam?} RE: Starting Process

Hi Frans,

Here are two methods I wrote in my JSPAdmin class which creates a prcoess 
and updates variables with values (given in a Map). This is of course 
basically the same as what Neville has already given you, but it may be a 
bit easier to use..

/**
     *  creates a process and sets some process variables
     *
     * @param  packageId          id of package
     * @param  processId          id of process
     * @param  variablesAndValues Map of vars and vals
     * @exception  BaseException, InvalidData, UpdateNotAllowed, 
AlreadyRunning, CannotStart
     */
        public void createProcessAndUpdateVariables(
                        String packageId, String processId, Map 
variablesAndValues) throws BaseException, InvalidData, UpdateNotAllowed, 
AlreadyRunning, CannotStart{
 
            WfProcess process = processCreate(packageId, processId);
            Map processContext = process.process_context();
            Set allKeys = variablesAndValues.keySet();
            Iterator iterator = allKeys.iterator();
            while (iterator.hasNext()) {
                String nextVariable = (String) iterator.next();
                if (processContext.containsKey(nextVariable)){
                                processContext.put(nextVariable, 
variablesAndValues.get(nextVariable));
 process.set_process_context(processContext);
                        }
                        else {
                                throw new BaseException("variable " + 
nextVariable + " not found as a variable for this process");
                        }
            }
            process.start();
        }

public WfProcess processCreate(String pkgId, String pDefId) throws 
BaseException {
 
                SharkConnection sConn = null; WfProcess process = null;
                sConn = Shark.getInstance().getSharkConnection();
                try {
                        //if (!isProcessRunning(pkgId, pDefId)) {
                                sConn.connect(userName, password, 
engineName, null);
                                process = sConn.createProcess(pkgId, 
pDefId);
                                sConn.disconnect();
                        //}
                }
                catch (Exception e) {
                        e.printStackTrace();
                        throw new BaseException(e);
                }
                return process;
        }

hth,
Geeta

{Spam?} RE: [shark] Starting Process






Hi Frans,

I'll Zap you a code snippet here, and put in a few comments on starting a
process with some variables ...


                 private static SharkMessage userNewProcess( 
SharkConnection sConn,
SharkMessage sharkMessage ) {
                                 String pkgId = 
sharkMessage.getPackagename();
                                 try {      // This Part ensures that a 
the package is loaded

 if(!sharkPa.isPackageOpened(
sharkMessage.getPackagename() ))
                                                                 pkgId = 
sharkLoadPackage(
sharkMessage.getPackagename() );
                                                 else
                                                                 pkgId =

                                 } catch (Exception e3) {
                                                 pkgId = null;
                                 }

now loaded,

                                                 sharkMessage.setResult(

                                 }
                                 return sharkMessage;
                 }
 

Hope this snippet helps with starting your processes ...

Subject: [shark] Starting Process

Hi All,

Now I am starting to create an instantiation.

i got there is 3 procedure in processStart

public static void processStart(String mgrName) public static void
processStart(String mgrName, SharkConnection sConn) public static void
processStart(String pkgId, String pDefId)

because i am still new in Shark, anyone can help?

I want to make an instantiate with automatic start this mean will make the
state open.running.

and after the state running, i want to inject the variable, so all the 
next
user for approval just approve.



i got this procedure
public static void variableSet(SharkConnection sConn,
                                          String activityId,
                                          String vName,
                                          String vValue)

but i still cannot understand, what happen if all the variable in XPDL 
is more than 1,

anyone can help this concept?

Frans
