I am trying to figure out how to take care of the events based on user input. Say for e.g., we
have a form where the manager can accept of reject the request. So the form should be having the
"Accept" and "Reject" buttons. When the manager clicks on "Accept" what happens ? Basically
we can set a process variable to have the outcome, say if "Accept" then process variable outcome
is set to 1. Else it is set to 0. I looked at XML code for sample application and did not find anything
related to submit buttons. I also could not locate the ftl files of the sample application in the Console
Server war file. Do I have to do this in code by creating a Mina task client and then interacting with the
task service ?
I thought this should have asked many many times before in the forum but on browsing did not find
what I need. If it is already there all I need is a link to that article. Also it will help if I know where
the ftl files for the sample application are stored.
Thanks for your help

I'm looking for the source code files.
Because when I run

private org.jbpm.task.service.TaskService taskService;
...
...
localTaskService = new org.jbpm.task.service.local.LocalTaskService(taskService);
I get

[jBPM] - Reading User Form Variables
by Bhaskaran Venkataraman
Bhaskaran Venkataraman [https://community.jboss.org/people/bhaskarven] created the discussion
"Reading User Form Variables"
To view the discussion, visit: https://community.jboss.org/message/738639#738639
--------------------------------------------------------------
I have a question regarding the User Forn variables. I was under the impression that freemarker template (ftl)
files have to be created for user forms. But I was able to run the HelloProcess example discussed in this forum.
I believe the XML code creates the user interface form.
1. I tried to read my own ftl file by changing the TaskName property in the XML. I have the Hello.ftl deployed
in the resources directory of the project as I have seen it in an example. But it does not display my form.
It is still reading the hardcoded contents in the XML
| | <dataInputAssociation> |
| | <targetRef>_4_TaskNameInput</targetRef> |
| | <assignment> |
| | <from xsi:type="tFormalExpression">Hello</from> |
| | <to xsi:type="tFormalExpression">_4_TaskNameInput</to> |
| | </assignment> |
| | </dataInputAssociation> |
2. I see a complete button to submit the form. But that is not harcoded anywhere in the XML. Where does it come
from ? The XML file of the BPMN diagram is attached for your reference.
I would like to read my own ftl files rather than hardcoding the contents in the XML. In the Developers Guide I saw
an example where the ftl file is included in the XML with the following construct. But I do not have any examples
on that usage of how input/output is done through the form.
<userTask id="requestVacation" name="Request Vacation"
implementation="other">
<potentialOwner resourceRef="user" jbpm:type="group">
<resourceAssignmentExpression>
<formalExpression>user</formalExpression>
</resourceAssignmentExpression>
</potentialOwner>
<rendering id="requestForm">
<jbpm:form>org/jbpm/examples/bpmn/usertask/taskform/request_vacation.ftl</jbpm:form>
</rendering>
</userTask>
Your response will be highly appreciated.

I'm using drools 5.4.0 and jbpm 5.3.0.
I'd checked the drools-core-5.4.0.Final.jar and org.drools.command.Context is no longer there.
Any idea?

Max, just wondering what you exactly mean by this. Do you mean adding everything by default to the standard JBoss server runtime, or providing an optional JBoss server runtime that includes everything?
As mentioned, I agree that it might be a good idea to only provide API classes in the standard runtime (shield most developers from accidentally linking to implementation classes).
But if you mean the second thing, I don't see how not adding everything would not be a solution for advanced developers who simply need everything?
Currently the AS 6 runtime includes almost everything, but you guys have forgotten a few jars here and there and indeed me and some of the other developers on my team have run into problems missing exactly those (if I remember correctly, it was e.g. the timerservice in common/deploy/ and some Tomcat related classes). The workaround is to add those jars to your project's classpath, but don't export them to the deployment. This allows you to do ctrl-t, call hierarchies, etc. It's a bit of a hassle, as basically you do want to keep those jars out of version control, so you have uncommitted changes in your project all the time and have to redo this at every location you work.
The point is that there are always cases developers run into. I find it hard to think of any jar or class in JBoss that should always and permanently be 'hidden'.
