Could not parse svg error while using image rest call

Hi:

I am using jbpm 6.4 and I am trying to use the ...../jbpm-console/rest/runtime/{deploymentid}/process/{processiddef}/image/{procid} rest call and I get the error:

.......java.lang.RuntimeException: Could not parse svg......

this error is throw by jbpm-process-svg at the point org.jbpm.process.svg.SVGImageProcessor line 67

I also tested with jbpm 6.3 (upgrading the jbpm-console-ng-rest.... jar) and I get the same error.

I did all the preparing steps (like changing <storesvgonsave enabled="false"/> to true and saving again the process). I am sure that the svg is being generated in the kjar because when I call ...../jbpm-console/rest/runtime/{deploymentid}/process/{processiddef}/image (without the procid) I get the image for the process.

I started my process and while it's waiting a human task response I've made the rest call before getting the error.

What I am doing wrong?

Regards,

Maciej Swiderski

could you share complete stack trace? That way we could see what is happening and what might be the source of the issues.

Could you also provide the contents of the svg file (that is stored next to the process)? It's complaining the content isn't well-formed but not clear why.

Hi Kris, of course I could provide the svg file, however as I told you when only using ..../image (without procID), it works perfectly so in theory the svg image should be well formed.

Attached the svg file.

Any hope with what's wrong with this rest call. What could I do?

Finally I found the problem. When saving the *-svg.svg image in the kjar it does not translate characters like < o > to < or > inside BPMN object labels. I had a couple of them in my business process. I removed the > and < characters (less than, greater than) from the labels and now the rest return the correct image.

Question is how to avoid this? which program should be corrected. I have all the git programs for 6.4.x branch so I could post a fix. It would be easier if someone has the name of the java program that saves the svg file.

By the way, I pulled the last change made for the jbpm-console-ng-rest module. I seems that the rest path was changed. But it gives an error when you try to use the rest for starting a process. It's not found since the path for jbpm-console-ng-rest have the same signature. Going back to original library remedies the problem.

Hope this will help someone.

I believe it should be fixed in designer that saves svg. Could you please drop jira for it?
