1. Re: Unicode in jBPM

Let me get this clear. Do you mean the character you wrote in your definition does not match the output in the webapp, right? If this is the case, it is probably an encoding issue.

Make sure you explicitly specify the encoding your document uses in the XML declaration:

<xml version="1.0" encoding="utf-8"?>

.
Also verify that your text editor is actually storing the file as UTF-8. In Eclipse, right-click on your file and select Properties. The frame Text file encoding reports the encoding and allows you to change it if necessary.

and what about the database? How does a database (e.g. mysql configured for ISO8.... and not utf-8) react if you send it 'wrong' data.

Thanks for soon answer.
But there are two error:
ex:
1. If i change in my GPD:

* select TestJoin.par in package explorer.
 * select properties->text file encoding(tab)->other(utf-8).
 * save and deploy to server.

when i start at http://localhost:8080/jbpm it is OK.
Next, i login with default user, i see my process is displayed with Unicode font.
BUT: when i click to start a process, some error bellow:

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

Please help me.
Do any one have this error ????

The first stack trace does not help at all. Please go to the Tomcat logs and copy the full stack trace.

Koen might be able to give you a solution for the second problem. They are connected, though. We should focus on the first one and see if that helps solve the second.

kukeltje Nov 24, 2005 3:39 AM (in response to pjmvn)

ok... it's obiviously in displaying the processimage on the task page. Can you try to remove that tag from the task.jsp and see if it works?
