User Task form display popup error Unable to complete your request.

[Bora]

Hi, 

sorry , newbie here. I am trying to run a process in jBPM with a task form linked to an object variable (my own class).

I can see the variable class in both web kie workbench and eclipse, and I have designed the form using the class structure.

However, when I run the process instance and I get to the user task from the workbench (I try to Claim the task in the tasks list), the form does not open, popping up an error

Unable to complete your request. The following exception occurred: com.thoughtworks.xstream.mapper.CannotResolveClassException (+ the name of my class)

As i have the debugging printout in the OnEntry script in the task, I am pretty sure the class exists :). I am , however, unable to find out what is wrong. I suspect something is wrong in the process - to - from variables mapping, but I am unable to tell what is wrong.

Any hints what should I check?

Thanks 

Bora

that means the class is not on kie server class path or kjar class path. Where is you class located? in workbench WEB-INF/lib or?

Thanks a lot for response, Maciej.

We do have the class in the overall jar for the project (we have checked that). This jar is loaded and registered by the kie server from the maven dependency:

[0m [0m13:24:24,016 INFO [org.drools.compiler.kie.builder.impl.KieRepositoryImpl] (EJB default - 1) KieModule was added: ZipKieModule[releaseId=cz.datlowe:rpa:1.0.0,file=/opt/jboss/.m2/repository/cz/datlowe/rpa/1.0.0/rpa-1.0.0.jar]

...

[0m [0m13:24:27,746 INFO [org.kie.server.services.impl.KieServerImpl] (EJB default - 1) Container rpa_1.0.0 (for release id cz.datlowe:rpa:1.0.0) successfully started

The class name is cz.datlowe.rpa.RpaShowcaseDao_Intent. 

I do have this OnEntry script in the user task

System.out.println("starting processClientChange");

RpaShowcaseDao_Intent oi = (RpaShowcaseDao_Intent) kcontext.getVariable("intent");

System.out.println("got intent for client " + oi.getClientName() + " " + oi.getClientSurname());

This works, i get the printout in the log, so I am sure at least part of the kie server knows about the class. The process variable intent of this class works just fine.

The problem starts when I want to open the form that is based on this class.

I have defined an Intent form variable (of the class RpaShowcaseDao_Intent; I can see the class in the form designer)  with the two IntentIn and IntentOut "faces" and defined the I/O mapping in the process User Task as per the screenshot

as you can see, the process designer knows about the class, and, as I said, the class works just fine in the process instance. It is however not recognized by the "form instance".

Any hint? It must be really something stupid, as this is a simplified copy of the manual example. And the form designer is happy, the process designer is also happy, it compiles ok, the process runs using this class in a process variable, just the form does not open :(

Thanks a lot in advance

there is no error in the kie server output :(, just the popup box in the workbench web app as follows

is there any other place to look for the log then the stdout?

just for info, this is the stdout log i am looking at, contains jbpm warnings/info and my debugging scripts. It passes through several (script and Service/REST) tasks and at the end stops at the processClientChange User taks - and thats it

(i started a new process instance after that just to make sure everything gets flushed to the log)

Just additional info: we build and deploy using maven, not the Build & Deploy workbench button

[Maciej Swiderski]

maybe workbench does not have access to this kjar/class… try putting this jar that has the missing class in workbench (kie-wb/jbpm-console) WEB-INF/lib directory and see if that helps in anyway?

Yes, that helped, thanks a lot, Maciej.

However, that is probably not an ideal solution, is it? Is this a sort of an issue, or are we doing something wrong?

Thanks a lot anyway for your help

[Maciej Swiderski]

Correct, it’s not the expected way but then we know what is causing the problem. So is that class in the kjar or? If it is maybe workbench does not have access to maven repo that contains it. This is clearly a configuration issue and I supsect it is related to kjar/maven part

Hi Maciej,

our configuration is as follows.

We have two servers: jbpm-workbench and kie-server

jbpm-workbench is the owner of maven repo with configured org.guvnor.m2repo.dir property in standalone-full.xml file.

<property name="org.guvnor.m2repo.dir" value="/app/repo/.m2/repository" />

The jar is located in the following path

/app/repo/.m2/repository/cz/datlowe/rpa/1.0.0/rpa-1.0.0.jar

When I put the jar into WEB-INF lib, the error goes away: /opt/jboss/wildfly/standalone/deployments/jbpm-console.war/WEB-INF/lib/rpa.jar

Is there some other configuration which eventually fixes the configuration?

Thanks

Martin

[Maciej Swiderski]

the only thing that comes to my mind is that it fails at loading the kjar some how. If possible you could try to debug it 

https://github.com/kiegroup/jbpm-wb/blob/master/jbpm-wb-kie-server/jbpm-wb-kie-server-backend/src/main/java/org/jbpm/workbench/ks/integration/KieServerIntegration.java#L279

Do you see anything like this warning in server log?

https://github.com/kiegroup/jbpm-wb/blob/master/jbpm-wb-kie-server/jbpm-wb-kie-server-backend/src/main/java/org/jbpm/workbench/ks/integration/KieServerIntegration.java#L298

Actually in the log of the kie server it says it loads it correctly

[0m [0m16:20:04,529 INFO [org.kie.server.services.impl.KieServerImpl] (EJB default - 1) Container rpa_1.0.0 (for release id cz.datlowe:rpa:1.0.0) successfully started

and the "process server" uses the class ok (I have variables of the class on process level and manipulate them with no problem). The only issue is when I try to load the form that uses this class.

Might the problem be in this line?

So the question now is: what are the screens.impl.LibraryIndexers and why can't they index the jar? and why can't the formModeler load this class? (and the other form CAN load the other class). I suspect Class not found is therefore probably misleading; what else can be wrong with the class? 

Thanks a lot
