Why do I keep getting "Please wait while the image is being generated..." message for my Process thumbnail?

You will get this only when you're viewing the process for the first time and only if your process is very complicated, with many activities.  It will then require some time to generate the image. Sometimes,  it can also take very long because of multiple processes in your app.  Generating the previerw image for each process can take a longer time.

This is due to the image being too large, thus, requiring more memory to process the image preview. In that case, you may need to increase your Tomcat memory setting by following the steps below (which will double the default memory setting). &nbsp;

Wiki MarkupNote: If you get a "black" preview image instead of the process preview image, you will need to delete the generated images located in&nbsp;\located in [Joget Installation Directory\]/wflow/app_xpdlImages/\[App Id\] and refresh your browser. A new image will be generated again.

How do I get my "system key"?

You can update your Joget by following these steps:

1. Stop Joget.unmigrated-wiki-markup
2. Delete "jw" folder, "jwdesigner" folder, "jw.war" & "jwdesigner.war" in your "\[Joget Installation Directory\]/apache-tomcat-6.0.18/webapps".unmigrated-wiki-markup
3. Delete "jw" folder, "jwdesigner" folder in your "\[Joget Installation Directory\]/apache-tomcat-6.0.18/work/Catalina/localhost".unmigrated-wiki-markup
4. Place the downloaded "jw.war" & "jwdesigner.war" in "\[Joget Installation Directory\]/apache-tomcat-6.0.18/webapps".
5. Start Joget.

Note: If the Workflow Designer does not show the correct build number in the window title, you will need to clear the Java Web Start Cache for your client machine.

Stack trace can also suggest meaningful error messages to help troubleshooting. The stack trace will be logged into the logs folder of the server container, Apache Tomcat.

Can Joget Workflow Apps be protected from unauthorized copying?
