Unable to generate PNG document from the Web Designer 2.0.

[vsarmien]

We have just installed jBPM 5.2 from the full installer (jbpm-5.2.0.Final-installer-full.zip) on Windows.  We haven't been able to generate the PNG document from the Web Designer 2.0.  If we use the options "Share Process Image" from the top toolbar, we get the following error message: "Failed to create the process image".

If we use the PNG button at the bottom of the Web Designer,  we get the following error messages.  (I have included the error shown on the web page, as well as the error shown in the server.log file)

Thanks for reporting the issue! As mentioned on your other post regarding generation of process PDF, replace your designer war with the one here: http://people.redhat.com/tsurdilo/designer/master/ and let me know if you are still running into any problems.

[vsarmien]

Thank you very much Tihomir.  It worked perfectly!

[w39hh]

Thanks. Had the same issue, the version of the war provided by Tihomir solved it.

[tsurdilovic]

Glad to hear. As soon as we accumulate a number of  fixes we can/will release 2.1 ... so keep reporting !

Hi Tihomir,

First of all thanks for the jar. I tried the jar mentioned in this file, it worked for small processes which din't cross the canvas, but while i tried to share the image for a large file, I got this error.

[org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/designer].[TransformerServlet]] (http-localhost-127.0.0.1-8080-4) Servlet.service() for servlet TransformerServlet threw exception: java.lang.ClassNotFoundException: com.sun.image.codec.jpeg.TruncatedFileException from [Module "deployment.designer-2.0-jboss7_png_fix.war:main" from Service Module Loader]

Also While I tried the PNG button at the bottom of the page, I just kept waiting as the server did not respond.

I just got this line in the server log, but i din't had any problems trying to access to the url...

15:52:36,804 SEVERE [com.intalio.web.server.TransformerServlet] (http-localhost-127.0.0.1-8080-16) Server returned HTTP response code: 505 for URL: http://localhost:8080/drools-guvnor/rest/packages/defaultPackage/assets/Create Lending Prospect/source/

I'm not sure why the resource is not accessible whether its because of the space in the file name or because the file is large.

So, I got the process image from eclipse and uploaded it to guvnor, but I don't get that in my process definition (http://localhost:8080/gwt-console-server/rs/process/definitions)

{"definitions":[{"id":"LEND.PROSPECT.ONBOARD","name":"Lending Prospect Onboarding","version":0,"packageName":"defaultPackage","deploymentId":"N/A","suspended":false},{"id":"Test2Id","name":"Test2","version":0,"packageName":"defaultPackage","deploymentId":"N/A","suspended":false,"formUrl":"http://localhost:8080/gwt-console-server/rs/form/process/Test2Id/render","diagramUrl":"http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/defaultPackage/LATEST/Test2Id-image.png"},{"id":"com.sample.evaluation","name":"Evaluation","version":0,"packageName":"defaultPackage","deploymentId":"N/A","suspended":false,"formUrl":"http://localhost:8080/gwt-console-server/rs/form/process/com.sample.evaluation/render","diagramUrl":"vfs:/D:/JBPM_POC/jBPM5.2/content/jbpm-gwt-console-server.war/WEB-INF/lib/jbpm-gwt-graph-5.2.0.Final.jar/com.sample.evaluation.png"}]}

I have the image file for the process with id LEND.PROSPECT.ONBOARD in the default package (name of the file being LEND.PROSPECT.ONBOARD-image.png) , but i can't see that in the process definition even after building the pacakge.

Any ideas / fixes  will be very helpful.

Thanks & Regards,

Aparna

Can you attach your process BPMN2 so I can test? There are some issues currently with expanding the default stencil set width/height which we are working on.

[a_nat]

The BPMN is attached along and it uses a workitem whose definition goes like this.

import org.drools.process.core.datatype.impl.type.StringDataType;

[

// the Notification work item

[

"name" : "ManualTask",

"parameters" : [

"Actor" : new StringDataType(),

"Comment" : new StringDataType(),

],

"displayName" : "Manual Task",

"icon" : "icons/manual_task.jpg"

]

]

Aparna

Hallo Tomislav !!

I have the same problem like Victor and the logs a the same.

File not found

Firefox can't find the file at http://localhost:8080/designer/transformer?uuid=4ce60bdb-18e0-4580-9ad3-0b40e28bb0bb&profile=jbpm.

I look in this site but do not find the solution how to fix it.

Can you help !!

Please

[catimage]

Hi Victor,

Good to hear that it's resolved. When I first encountered this issue, I thought I did something wrong. Didn't know how to work this out so I tested another little tool to create png. Now that I find this post here, thanks!

Regards,

Catherine
