[jboss-user] [jBPM] - Re: JEE + jBPM + threads
Chris Melas [https://community.jboss.org/people/melc] created the discussion "Re: JEE + jBPM + threads" To view the discussion, visit: https://community.jboss.org/message/816796#816796 -- Hi, Whenever the process reaches a wait state, such as a timer, it will return to the point where it was called. If you want the code to block then you can write any custom java code (aka workitem) even use a script task that does some kind of job or simply waits for some time. This is bad practice if you use a single persistent session, since the main thread will get blocked and not be responding to any requests. If you use multiple sessions e.g. session per request, i guess it will be fine if you don't mind about persistence, since blocking tasks do not get persisted, only on a wait state persistence takes place. Can you please explain why the thread creation worries you? Regarding issue 2 if you need to persist state then you should use persistent session and a common approach, as shown by the jbpm-gwt-console implementation, is to have a singleton session. So in your case you could use a singleton ejb initializing the session and providing it to the ejbs with jbpm related logic. If you need to scale, you may later on add some kind of a pool of sessions in your singleton bean. -- Reply to this message by going to Community [https://community.jboss.org/message/816796#816796] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2034] ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

Directly within designer i.e. you may even copy paste the content you have prepared. It is a small icon that appears when you select and hover a human task on your bpmn diagram, that looks like a person. If you click it the code of the ftl is presented and rendered real time as you edit it. 2.

One way of handling this is to place some logic before saving your data in order to check whether it actually needs to be saved or not. For example from your business logic i.e. do i have an entry for this entity with this id already? etc if it is not possible to have it from your logic then use the process instance id i.e. save the pid in a table associated to the specific entry. However the same problem you mention may happen at any point of your code as long as it does not belong to the same transaction, so having a way to force saving the state is the same as saving it from the process.

So the procedure would be to insert a domain specific work item and populate its attributes, then switch its type to default task the on entry/exit attrs will be presented, populate them and then switch the type back to your domain specific work item. Although a bit hacky it seems to work. However my opinion is to use script tasks before and after instead of the on entry/exit, since they are visible directly on the diagram and more clear to the reviewer. I haven't migrated to latest realease of designer yet to try it out, however i think it will probably work the same way. -- Reply to this message by going to Community [https://community.jboss.org/message/717880#717880] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2034] ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

Hi,
If i understood correctly, you can return results from your custom work item by
passing your parameters to the
*completeWorkItem(WorkItem workItem, WorkItemManager manager, Map results)* method of WorkItemManager object
i.e.
Map results;
results.put("result", resultObject); results.put("error",errorObject);
manager.completeWorkItem(workItem.getId(), results);
or even better from the StatefulKnowledgeSession object via
ksession.getWorkItemManager().completeWorkItem() .
Then you can assign the result mapping i.e from editors.

Hi,
I tried out your code on jboss7, mysql and it worked fine with the following
changes applied,
1. Introduce a KnowledgeRuntime field in your handler,
public class SaveStateWorkItemHandler implements WorkItemHandler {
*private KnowledgeRuntime session;*
public SaveStateWorkItemHandler() {
}
public SaveStateWorkItemHandler(*KnowledgeRuntime session*) {
this();
*this.session = session;*
}
..
2. Complete the work item in your SaveStateWorkItemHandler as follows,
System.out.println(" END SAVE-STATE SLEEP *");
*session.getWorkItemManager().completeWorkItem(myWorkItem.getId(), null);*
3. Register your handler accordingly,
*ksession.getWorkItemManager().registerWorkItemHandler("SaveState", new
SaveStateWorkItemHandler(ksession));*

As far as i can see the part of the bpmn from eclipse with the script
i.e.

will work if script tags contain namespace prefix i.e.

Hello,
So for the following case,
start->workItem1->script1->workItem2->script2->end
a) Yes by reaching script2 the workitem1 is completed and its entry is deleted
from the workiteminfo table. It also means that workitem2 has executed and by
failing at script2 you can only examine the NodeInstanceLog table to figure out
what has happened and maybe take some action. However i think the process
instance at that stage will not resume since there will be no associated
workitem persisted to execute/complete.
b) If workitem1 completes then it is deleted from the workiteminfo. But
generally if you pickup a persisted work item (other than a work item
associated with a human taskbecause a human task has an entry in the task
table as well and needs a bit more care i.e. whether the task has completed or
not etc) from the database you can either re execute it or complete it. These
are achieved by quering the database table workiteminfo retrieving the object
associated with the work item you want and calling either
YourWorkItemHandler yourWorkItemHandler = new YourWorkItemHandler();
yourWorkItemHandler.executeWorkItem(workItemFromDB,
ksession.getWorkItemManager());
+to re execute the work item+
+or complete it+
ksession.getWorkItemManager().completeWorkItem(workItemFromDB,
workItemFromDB.getParameters()/*or some other params etc*/);
The following bootstrap code can be used for non human task work items that
have not completed (i.e. system crashed while running) and choosing to re
execute them, as well as human task work items that have completed and the
system crashed right after the human task completion but before entering the
next wait point.
private void bootstrapForWorkItems() {
EntityManagerFactory emf = null;
EntityManager tempEntityManager = null;
List results = null;
try {
emf = (EntityManagerFactory)
ksession.getEnvironment().get(EnvironmentName.ENTITY_MANAGER_FACTORY);
tempEntityManager = emf.createEntityManager();
results = tempEntityManager.createNativeQuery("SELECT w.* FROM
WorkItemInfo w inner join Task t on t.workItemId=w.workItemId where
t.status='Completed' union SELECT w.* FROM WorkItemInfo w where name <> 'Human
Task'", WorkItemInfo.class).getResultList();
} finally {
if (tempEntityManager != null) {
tempEntityManager.close();
}
}
if (results != null) {
for (Object resultObject : results) {
WorkItemInfo workItemInfo = (WorkItemInfo) resultObject;
WorkItem workItem =
workItemInfo.getWorkItem(ksession.getEnvironment());
if (workItem.getName().equals("YourWorkItem1")) {
YourWorkItem1WorkItemHandler yourWorkItem1WorkItemHandler =
new YourWorkItem1WorkItemHandler(ksession);
yourWorkItem1WorkItemHandler.executeWorkItem(workItem,
ksession.getWorkItemManager());
}
if (workItem.getName().equals("YourWorkItem2")) {
YourWorkItem2WorkItemHandler yourWorkItem1WorkItemHandler = new
YourWorkItem2WorkItemHandler(ksession);
YourWorkItem2WorkItemHandler.executeWorkItem(workItem,
ksession.getWorkItemManager());
} else if (workItem.getName().equals("Human Task")) {
/*i'm not sure about the workItem.getParameters() here, might be getting the
params of the previous human taskmight need a little fixing*/
ksession.getWorkItemManager().completeWorkItem(workItem.getId(),
workItem.getParameters());
//or
//call correct workitemhandler for this task and re execute
}
}//for - results
}//if - results
}//method
Of course in some cases you may choose to act differently i.e.instead of re
executing a work item, complete it because you checked your business logic
(i.e. checked your system's database) and realised that data has been commited
or web service has been called but the jbpm engine system crashed right before
erasing the workitem etc.
c) By quickly looking at your code and log i see that workitem1 executed then
script1, followed by workitem2 and script2 so i think it went fine. I'm
not sure i get the problem.

The only place to see that a signal has been reached by an instance of your process, is the NodeInstanceLog table. If you examine the entries you can find out whether a signal has completed or not. Then you would have to somehow figure out the ref of the signal and make a call as you would from your external process and continue. So if i understand correctly you want your process to wait at the signal and somehow an external event is called by your system to continue.. Otherwise if you only try to persist just make workitem1 asynchronous and omit the signal part i.e. start->script1->workitem1->script2->workitem2->end. That will persist your work item until it gets completed. So if it fails while running you can get the work item from WorkItemInfo and rerun it , otherwise if it completes the process will continue to script2 and so on. please correct me if i havent understood your intention -- Reply to this message by going to Community [https://community.jboss.org/message/649142#649142] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2034] ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

To overcome such a scenario, you would need to persist the work item before calling the web service. Generally when you create a workitem, in order to have its state persisted, by the engine, you need to run it asynchronously, i.e. within a new thread. When the system is recovered you would need to re run this work item. If you want to perist the state of the process right after the web service is called, in other words when the work item is completed, you can simply call another asynchronous work item right after the call of you web service work item. In addition a human task could be used, if it makes sense. However, what if the system goes down before completing the ws work item but after the ws call? Then you need to apply some kind of logic in your system that runs the ws call within a transaction and modifies some kind of state, that you will check when trying to rerun the work item after a process recovery. -- Reply to this message by going to Community [https://community.jboss.org/message/647369#647369] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2034] ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

Can you think of other examples (like the > timer) where an external pause/resume would not work? In order to manage the way different types of processes (i.e. type A - low priority, type B - high priority etc) are run, i suggest the following concept of an approach which involves a little custom work, 1. A small infrastructure for actually pausing any process before executing a work item. This can be achieved by initialy associating some kind of flag with each process started. Then create a central base abstract work item handler, which all your work items will extend, having a logic at the start of each executeWorkItem(..) method where a check to the flag would take place. If the flag is up then the execution continues, else if the flag is down it sits there and waits until the flag is up. Of course this will have to run asynchronously within a new thread at least for two reasons a. so not to block the engine b. to persist and continue all processes if the engine goes down at any point. This way you will be able to pause processes at the start of a work item. You will not be able to pause a process while running a work item's logic, unless you place appropriate logic of persisting state at any point of execution, then resuming everything etc, this is hard, not very efficient (well depending on the work done at each instant of time on each work item of each process) and error prone. 2. An object acting as a controller containing all the business logic related to priorities and relations of processes. This controller would decide whether a process has to be paused or resumed etc by raising or lowering the flag of the running processes. The controller would probably run when starting each process, in order to decide what to do with the other processes running or the current process etc. -- Reply to this message by going to Community [https://community.jboss.org/message/646889#646889] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2034] ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

Hi,
I'll try to see how each of your reqs are solved with "out of the box"
functionality

- So, task1 and task2 are assigned to a group - ok
- The id of the actor that completed task1 will have to be mapped to a process
variable - ok ( can be done either by using #{some expression} or a little
magic around kcontext within the on exit action etc)

- Assigning the actor based on the variable value is ok. however i'm not
sure what happens if both actorid and groupid are present in task1 whether
the actorid will supersede-> although you can always place a task3 which is
the same as task1 and everything works fine.
- Regarding the "unless" part this is a little strange, because if the actor no
longer exists and you assign the actorid
the following might happen (sry havent tried it)
a. the system complaints that the specific user no longer exists
b. the system has no problem that the users no longer exists and the group part
works - then all ok
keep in mind that i'm talking about zero code situations i.e. not even
user-group callback etc
If the actor exists but no longer part of the group then this gets complicated.
Because, if the user exists then the actorid will be assigned along with the
groupid, but the engine must not assign it to this user since is not a member
of the group - not ok (this i'm almost certain that will not work for this
engine as well as two more i.e. activiti and intalio, in jbpm this can be
achieved with a little programming in a clean manner).

Although it is pretty straightforward to implement jax-rs and jax-ws with work items, there will also be available some interesting implementations in the public repository ( http://kverlaen.blogspot.com/2011/10/introducing-service-repository.html http://kverlaen.blogspot.com/2011/10/introducing-service-repository.html , http://kverlaen.blogspot.com/2011/12/jbpm-52-released.html ) . 2)The state of work items is always stored before and after execution. The only thing that you may need is to have some kind of logic executed in case the system breaks down while executing a work item in order to specify how you want to react for the stored work items that may not have completed execution i.e. restart execution or complete automatically etc. 3,4)I think this mainly depends on the app server you'll be using i.e. Jboss provides ha clustering solutions , as far as jbpm5 is concerned you'll be fine. Basically treat jbpm5 as you would with any other jee application. 5)Yes, there is a console and repository already for jbpm. However you can also implement your own or simply use the available api to do actions like that, it all depends on how you plan to use jbpm i.e. in the core of your app, as a service etc - no problem with oracle many people have been using it - quartz is not required by jbpm5 to function -- Reply to this message by going to Community [http://community.jboss.org/message/641243#641243] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2034] ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

That is a quick solution, alternatively you can also write your own gwt-console-server or as you already mentioned embed everything in one web application. 1. I think the console that comes shipped in the installation is mostly great for testing purposes . For a real application you will probably need to modify layout/style and captions, display extra information (i.e. from your business domain) or remove some, maybe i18n etc. The communication with the process engine is done either by using the existing gwt-console-server or writing your own module using the jbpm5 engine. 2. Yes you can certainly have everything in one web app, however by having the logic on a server component you can actually retrieve information and interact with your process engine from other systems as well. For example you may want another app's screen to show the tasks that are pending for a specific user, nothing elseOf course you could publish web services from your web app but that is less loose coupled and not modular. A good example is gwt-console/gwt-console-sever we are able to create a different console client by reusing the server component. Also the console client is being used by other jboss modules of other frameworks (server components) i.e. Riftsaw, DroolsFlow 3. I would advice to simply write your own integration layer that basicly handles the communication with the REST API of the gwt-console-server you can find info regarding the available methods from your jbpm5 installation http://10.1.3.26:8082/gwt-console-server/rs/server/resources http://yourJBPMServer/gwt-console-server/rs/server/resources It gives you flexibility on the way you delegate control to the server and how you retrieve data. However the code of the console is here, https://github.com/heiko-braun/bpm-console https://github.com/heiko-braun/bpm-console as well as docs. 4. As bpmn2user mentioned there many design options so It really depends on the imlementation you choose... .whether you use directly the process core engine that you keep in your application or with a server component that handles a process engine i.e. the existing gwt-console-server -- Reply to this message by going to Community [http://community.jboss.org/message/640598#640598] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2034] ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

Hello,
If you take a look inside build.xml at the target start.demo you will see that
all it does is to start jboss, h2, human task, eclipse. So in a
production/development/staging server environment you will probably use an
RDBMS that is always started, so no need for start.h2, you will probably not
care if eclipse is started at your server or even on your system you can start
eclipse yourself so no need for start.eclipse. Now regarding jboss of course
you will always need to start jboss, possibly with your own parameters.
Starting jboss through ant i.e. ant start.jboss is like run from bin folder of
jboss, however it also sets some parameters (i.e. memory related, bind address
etc) so you can either set those parameters or your own parameters in run
script of jboss or simply use the ant mechanism which is pretty flexible and
straight forward.
So basically all you need is *ant start.jboss* if running from ant or execute
the jboss run script. Regarding the human task you also have to start it
because it is a separate java application. So you can either run it localy by
calling *ant start.human.task*, or you can wrap it in a web application deploy
it on jboss and no need for ant start.human.task.
Please note that if you take the human task web application route, in order to
propertly initialize the users, groups and the database tables (the first
time), you will have to make an http request to the human task web application
when the server starts. This is easily done in ant, for example add the code
below inside the start.jboss ant target just before the closing tag
+...+
++
++
**
*http://${jboss.bind.address}:yourPort/TaskServiceWebApp"/>*
**
**
http://${jboss.bind.address}:yourPort/TaskServiceWebApp";
dest="${install.home}/" />
**
So to conclude,
either call +ant start.jboss;ant start.human.task;+ or +bin/run .; ant
start.human.task;+ or +the call to start.human.task can also go inside the run
script +
or make the human task a web app and just call ant start.jboss with the extra
code above.

Hi,
I'm very glad to have assisted in any way and thank you very much for your kind
words.
If you use jbpm-gwt-console-server then you should use the knowledge session
provided by the console-server, as you have noticed.
At first glance things are not very flexible, but there is a way of extending
them in a little dirty approach.
To understand the context, the jbpm-gwt-console-server provides a REST API by
communicating with the jbpm5 API through some integration classes.
The REST API classes as you have spoted are inside the
jbpm-gwt-console-server.war and the integration classes are in
org.jbpm.integration.console package of the jbpm5 sources. So in your case
inside ProcessMgmtFacade (from the REST API) there is a field processManagement
of type org.jboss.bpm.console.server.integration.ProcessManagement, which has
another field called delegate of type org.jbpm.integration.console.Delegate.
The delegate field initialises all jbpm5 knowledge related objects, such as the
ksession (StatefulKnowledgeSession). So this is what you need
The proble is that it's private and all accessors are either private or not
really what we could use to extend and somehow get hold of delegate and
ksession etc.
So the approaches are,
1. Edit the other classes , or inherit from them (i.e. the integration classes)
and expose the field/methods that would provide what is needed. Then provide
the new implementations in the already edited ProcessMgmtFacade .
2. Create your own implementation/use of all i.e. your own web services,
instantiated as in jbpm-gwt-console-server etc so in other words create your
own little system with jbpm-gwt-console-server as a reference implementation.
3. Use the dirty old reflection in an inappropriate manner as i show below
:)
So the dirty approach is to use reflection accessing private method/fields :0
i.e.
//inside ProcessMgmtFacade in your web method (this is the idea, haven't tested
this code i write it here directly)
Field fields[] =this.getClass().getDeclaredFields();
for(Field field : fields){
if(field.getName().equals("delegate")){
field.setAccessible(true);
field.get(this);//this will return the delegate object, so you can do the same
to retrieve the ksession field
}
}
Generally, if there is no other way of doing it properly i.e. via inheritance,
or accessing some other object that will eventually give access to ksession ,
then the author of this code did not intend to give such access and one has to
provide his own implementation, possibly by reusing code etc as stated in
approaches 1 and 2.

Whether this approach is correct or not depends on your problem domain, we can discuss it if you want. Generally I believe it is a fine method for delegating the responsibility of managing the workings of the engine to some engine related controller.

Hello,
You can get any node you like
i.e.
WorkflowProcess workFlowProcess = ((WorkflowProcess)
knowledgeBase.getProcess("yourProcessId"));
nodes = workFlowProcess.getNodes();
then you can loop and cast to whatever node you want look at the types in
package org.jbpm.workflow.core.node i.e. there is a HumanTaskNode etc
i.e. finding the start node
Node startNode = null;
for (Node node : nodes) {
if (node instanceof StartNode) {
startNode = node;
}
}
you can even traverse your process
i.e. call the following method as traverseProcessForHumanTaskNodes(startNode,
new ArrayList()); then it will return a collection with all the human
task nodes
public static Collection traverseProcessForHumanTaskNodes(Node startNode,
Collection nodes) {
/*you can choose on of your outgoing connections based on some logic*/
Node nextNode =
startNode.getOutgoingConnections("DROOLS_DEFAULT").get(0).getTo();
if (nextNode instanceof HumanTaskNode) {
nodes.add(nextNode);
} else if (nextNode instanceof EndNode) {
return nodes;
}
return traverseProcessForHumanTaskNodes(nextNode, nodes);
}
This is just to get you starting with a little debugging you will see that
everything is connected and you can easily retrieve it.

session.addUser(new User(testUser));

session.addGroup(new Group(testGroup));
Also make sure the database table OrganizationalEntity contains them.

So what you need to do is when the user visits that page (i.e. jsp page) the servlet/bean (or whatever) associated with the jsp will have to retrieve the tasks for that user and give them to the jsp to display i.e. a table/grid with all the tasks of that user and the option to select a specific task. Retrieving the tasks is accomplished by communicating with the human task service and when the user selects a task (i.e. by click a button right by the task entry of the grid, or the grid row etc) you will present a jsp/html/ajax (or whatever) page representing that task. The details regarding the task i.e. its parameters, name of the task etc will also be retrieved from the task service as well as the signal for completion.

These processes have to be accessed and started, as a result orchestrated, by the jbpm engine. You have two choices, 1. Use your own instance of the engine with your own configuration etc ( for example the code you have posted). 2. Use 'jbpm-gwt-console-server, which is a web application having all code and configurations needed for the jbpm engine to run. I understand that whatever the approach, you want a "fire and forget" solution. Such a solution is achieved by running an application as a service (i.e. run constantly and listen on a port of your system - not very nice) or as a server (i.e. create web application and deploy on an application server like jboss - then you have to use http calls to communicate with it - i.e. web services). Approach 2 above is ready out of the box (you have the engine running on a server and the communication methods - REST API - ready for you) and you have to communicate via REST. p.s. whatever the approach you will be getting all your definitions and resources from the repository of Guvnor -- Reply to this message by going to Community [http://community.jboss.org/message/623477#623477] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2034] ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

"display process diagram"
To view the discussion, visit: http://community.jboss.org/message/622889#622889
--
Hello,
I'm using jbpm5.1 and i noticed that when i add extra nodes to a process,
jbpm-console throws an exception (Could not find info for node new_id_of_node
of process the_process_id) when trying to display the diagram at the point of
reaching the new node.
Has anyone else noticed this??
Basically what happens is that
org.jbpm.integration.console.graph.GraphViewerPluginImpl has already
initialised kbase variable and within its method getDiagramInfo() ,the kbase
does not return the new bpmn diagram containing the new node. Everything else
works fine as it is normally updated, except the kbase of this class. If it
doesn't happen to anyone else then it's maybe my configs and i apologise.
However if this is the case one possible solution would be to make kbase=null
and call getDiagramInfo() after having checked first the bpmn file as is and
before throwing the exception i.e. right before line 93 of method
getActiveNodeInfo() where the check if (!found) {}
Any other ideas??
Thanks

Maybe also add your classes in jax-rs Application class org.jboss.bpm.console.server.ConsoleServerApplication as singleton (check the code of ConsoleServerApplication regarding the other jax-rs classes). Since you use the gwt-console-server API you'll need the objects created inside ProcessMgmtFacade so if you want to change existing functionality the simplest approach is to modify that (by adding new methods or changing existing ones as described in http://community.jboss.org/message/612597#612597 http://community.jboss.org/message/612597). If you want to use your own class to override functionality you could extend ProcessMgmtFacade with your own class and add all your new logic there. However in order to overide the urls you would have to define the same jax-rs paths in your file and maybe remove the same ones from ProcessMgmtFacade and probably have to modify the jax-rs Application class org.jboss.bpm.console.server.ConsoleServerApplication to add your class as singletonhaven't tried it to be honest and it gets a little messy. The fact is that on each update of jbpm, since you use the gwt-console-server, whether you make the changes in the existing code or on your own file, you will either have to make those changes or add your file each time. Not a good practice for large scale changes etc indeed but unfortunately no other extension points, to the existing REST API system i think. -- Reply to this message by going to Community [http://community.jboss.org/message/621035#621035] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2034] ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

Then at a gateway check the flag's value and decide whether you should raise an exception or not.

We had worked with drools in the past and it is a strong and proven platform. So not only because of the ability to add rules, but due to the fact that drools architecture is in the core of jbpm, hence they share sessions, objects, rules, facts etc. all this makes it quite powerfull. In addition i also like the way that human tasks and custom services are handled and created. Everything seems straightforward, modular and flexible. However, i must admit that Activiti is really powerfull as well and we keep evaluating both as releases come out. The toolset of Activiti is pretty powerful so due to the fact that both platforms use the bpmn2 standard we try to combine both technologies to some extend. -- Reply to this message by going to Community [http://community.jboss.org/message/615865#615865] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2034] ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
