How can I display processimage (jpg) in browser?

[lisaanm]

Hi.,
In my web application, users are allowed to upload/deploy processdefinition file directly from web browser and process workflow will be executed automatically.

In this scenario I want to display the processimage file (from the deployed processdefinition file) in the user's browser.


I'm a new bie to jbpm.
Please give me some ideas and I'll be grateful to you.

Thanks.

the process image is in the .par file. The image is created by the GPD. So just uploading the .xml file is not enough.

Thanks for your reply.

I want to know exactly how the GPD converts (or creates) xml file (processdefinition.xml or gpd.xml) to jpg image. I tried to connect to CVS for GPD source but timeout error (still trying).
If anybody knew about this process, please give me some ideas about it.

Thanks you.

We also have the need to generate a JPG from a processdefintion.xml file. the system is not using the gpd. we have a weclient and want to show the process as a flowchart (same like the gpd does)
is there a method like: Byte[] b = GpdUtils.createProcessDefinitionImage(ProcessDefiniton pd);

For the moment, I leverage simply the included GEF functionality. I have been thinking about generating the jpg image on the fly when deploying instead of at saving time.
I am not sure in what context you want to generate this image. But if it is not from within an Eclipse context, I have a feeling this is not an evident addition.

We also need to do something like this, the first idea is generate the jpg image from the jpdl definition. And without use the Eclipse IDE.

Salud!

Koen,

wouldn't you also need an auto-layout mechanism if just the jdpl file is available?

[koen.aers]

Yes this auto-layout stuff becomes more and more important now.
On the same note, have a look at : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3916845#3916845
