Instantiate process from application

[Luke Rasmussen]

We are trying to use the Shark API to instantiate (and interact with) a process from an external Java application. 

 

We looked in the Shark code (latest from CVS) and found the SharkTest area, however it appeared to have a lot of extra calls.  Our engine is running and the process is loaded, so what is the minimum amount of code needed to obtain a link to the server instance and instantiate it.  Is this already documented somewhere?  Has anyone done this, and would you be willing to post a simple example to the list?

 

Thanks in advance for your help.

Hi Luke,

Here's some code sample from our application, which may help you:

ut = SharkInterfaceWrapper.getUserTransaction();
ut.begin();

/*"xpdl" below is a domain object for us which has info about package
defintion, verison etc. and getProcessManager() is * a method I will
reproduce below.
*/
WfProcessMgr processMgr = getProcessManager(sharkConnection, xpdl);

process= processMgr.create_process(null);

/*if you want to set process variables now, then you can do so now as
follows:*/
process.set_process_context(myContextMap);

process.start();
ut.commit();

Here's the getProcessManager method using our xpdl domain object:
private WfProcessMgr getProcessManager(SharkConnection sharkConnection,
                  Xpdl xpdl) throws Exception {
      XPDLBrowser xpdlb = Shark.getInstance().getXPDLBrowser();
      String procDefName =
            xpdlb.getUniqueProcessDefinitionName(
                        sharkConnection.getSessionHandle(),
                        xpdl.getPackageId(),
                        (new Integer(xpdl.getVersion())).toString(),
                        xpdl.getProcessDefinitionId());
      WfProcessMgr mgr = sharkConnection.getProcessMgr(procDefName);
      return mgr;
}

Hope this helps,
regards,
Geeta

[Bhatti, Shahzad]

I need to add a fairly complicated authorization layer on top of shark. In my application, all users are already authenticated (logged in) and I need to check if they are authorize. I will be using both static roles such as regular users, managers, etc and instance based properties such as organizations, etc. Can someone point me to some sample code that does this. Thanks in advance.

        Hi,

 It seems your code would work only if after line:

     SharkInterfaceWrapper.setProperties("X:\\tws-community-2.2\\conf\\Shark.conf",
true);

 you put the following:

     SharkInterfaceWrapper.getShark();

 Sasa.

 We are trying to use the Shark API to instantiate (and interact with) a
process from an external Java application.

 We looked in the Shark code (latest from CVS) and found the SharkTest
area,
 however it appeared to have a lot of extra calls.  Our engine is running
and the process is loaded, so what is the minimum amount of code needed

Hi Luke,

Another thing to keep in mind: make sure you do not have nested
transactions. So for every ut.begin(); you should have a matching
ut.commit(); with no ut.begin(); *in between*. This is the meaning of "
javax.transaction.NotSupportedException: Nested transactions not
> supported" error you got. I myself got stuck with this error for a while
before I could figure out what was wrong!

Hope this helps:)

Hi,

 

We noticed that Shark will delete data from DB once task is completed. We prefer to keep DELETE privileges as restricted as possible. Is it possible to get a list tables Shark will need to delete from?

 

Thanks,

 

Jessica Zhao

Thanks Geeta, that's good advice!

I'm happy to report that we were able to get an example working, and fully executed a process without any errors.  Thanks again for all the help with this.

Hi,

when task is completed, shark deletes from DB only information about
assignees for that task. And this information is stored within table
SHKAssignmentsTable.

Greetings,
Sasa.

Hello all,

Its difficult to explain the situation but lets try....

I have a problem with lists and shark....
The shark process starts to run when a request from an outside program is
made (my program).

Situation:
My program first receives a list of arguments to a list variable type;
Sends it to shark let say "LIST_IN_VAR", also starting the process;
And after doing some work sends the same list to my program which will use
it to do more things...;
Shark don't really uses the list, at least in this example. It simply
receives and resend it to my program, but the list needs to enter in shark.

Problem:
The problem is that I can't used Lists in shark... so what I do now is:
LIST_IN_VAR is now defined as a string.
When a request is made, my program converts the list to a string and sends
it to shark
Shark do is work....And in the end
My program receives the "where to send" and the list as a String
Converts the string back to LIST and sends and continue doing its job....

How can I use the list type from shark?
It's possible to create a variable of type list and define a initial value??

Regards and thanks,
        Pedro

Hello Pedro,

I am not sure if maybe I misunderstand your question, but I hope you know
that arbitrary (custome defined) Java classes can be used as process
variables..? From the current version docs I see this: "you can define any
Java object to be a workflow variable (through the use of XPDL
ExternalReference data type), and then use it in shark (of course, this
class has to be on shark's classpath). "

In earlier version's docs, there was more on this topic here:

http://shark.objectweb.org/doc/1.1/HowTo/how_to.html#d0e360

Again, I apologise if I didn't get your question :)

Hello again,
I already familiar with that feature, and already tried a classed build by
me. But I couldn't solve the situation. For sure I'm not doing the things
right.

The only resolution that come to my mind was (using the example bellow):
(its different from the past one but I think the point is the same)
Let's suppose I have a start activity.
The transition from this activity loads the values(Static values) to the
variable defined using the class build by me, lets say "my list type"...
A is an instance of "my_list_type"!!! how can I create an instance?!?! This
is not the right way....
a.add(2);
a.add(3);
a.add(7);


The problem now, at least for me, is how do you instantiate the class?!you
need an instance right?!?! What I need to change?

So let's suppose:
MY_list_type is defined using the class my_personal_list.java bellow:
#########################################
private List real_list;
My_personal_list()
{
       
}
Add_value(int value)
{
Real_list.add(value);
}
Retrieve_list()
{
Return real_list;
}
#####################################



Regards,
         Pedro

Hi Pedro:

Here's how i would define my xpdl (again, I apologise if I do not
understand your situation correctly):

1. The xpdl has your custom defined process variable of class MyListType,
and MyListType is of course in your class path .
1. The xpdl has a start activity, which leads to an activity in the
*System* lane (ie performer is System and the activity is mapped to a Java
class, say, MyInstantiater which is also in in your class path). The path
out of this system activity leads to the rest of the activities for your
app.
2. The above Java class, MyInstantiater, has the logic needed to
instantiate your class MyListType as well as populate the custom defined
process variable.

Why won't this work?

Regards,
Geeta

Hi Geeta,

I was trying to follow what you said and some problems came...
- So I started to build a new process called "simple_process" (this way I
can learn, without destroying things I have already done).
- create a new workflow variable (list_var) of type LIST(basic type string);
- created a workflow participant (sys_participant) of type system;
- defined a Formal Parameter (list_input) of type LIST(basic type string);
- from my previous tests I can't introduce a list to this formal
parameter.....
        An error of something like "type not supported" always come up.

How can I use your way to do what I want?! Is this the right way?!
For sure it's something very simple but I'm not getting it! Sorry :(

Regards,
            Pedro

your class MyListType as well as populate the custom defined process
variable.

Why won't this work?

Hi Pedro, the reason you got thsi error ""type not supported"" is because
List is not supported as a type for a process variable. Only basic types
like String, Integer, Boolean etc are supported. So if you want to start
out building a "simple process" then start with one of the basic types.
Once you have that working then move on to more complex Java types. As I
mentioned earlier if you want a process variable which is of type List the
only way that i know how to do it is to build a Java class which will have
the List functionalty and then use it as I described earlier: "

> > you can define any
> > Java object to be a workflow variable (through the use of XPDL
> > ExternalReference data type), and then use it in shark (of course,
> > this class has to be on shark's classpath). "

So go step by step. Make sure you get a Basic type like Integer/String
working, then move on to an arbitrary java class.

Regards,
Geeta

Hello again

Sorry for long absence.... but I have been working on other project....

Geeta
Before the start of this issue I had already build up several process's with
simple types....
I'm not sure, but are you saying that I should use simple types as external
references to see if I understand the process off instantiate external
classes???

After some tries I continue to not understand how an activity will
instantiate my custom made class....

Could you, or some one, help me with this long time problem???
Thanks,
        Pedro
