Hi,

take a look here: https://developer.jboss.org/thread/253694

There Maciej provided a workaround to be installed in the wildfly module folder. For me this resulted in problems, when using the CDI services, but perhaps that is a configuration problem in my application.

Regards

J.

Hi Jimmy

thanks for your reply. I checked this, and with simple ear (using cdi) it works then but with my ear I recived:

Caused by: java.lang.Error: Unresolved compilation problem:

do you know this error ?

Yes,

I had the same problem. I changed the provided sources (removed an "override" annotation) and it worked.

I would attach the jar, if I would know how to attach a file. Haven't found a way to do this in the forum.

Edit: See attached file.

[franco80]

I had write that i solved it but I see that you added solution, anyway thanks !

I added this only and it works then:

     <build>

        <plugins>

            <plugin>

                <groupId>org.apache.maven.plugins</groupId>

                <artifactId>maven-compiler-plugin</artifactId>

                <configuration>

                    <source>1.7</source>

                    <target>1.7</target>

                </configuration>

            </plugin>

        </plugins>

    </build>

I'm using WIldfly 8.2 and there is jboss-transaction-api_1.2_spec.jar with UserTransaction but inside fake-ut-bind-1.0.0.jar is jta 1.1. It's not important now but in future may be a compability problem.

instead of:

<dependency>

    <groupId>javax.transaction</groupId>

    <artifactId>jta</artifactId>

    <scope>provided</scope>

    <version>1.1</version>

    </dependency>

use this:

<dependency>

        <groupId>org.jboss.spec.javax.transaction</groupId>

        <artifactId>jboss-transaction-api_1.2_spec</artifactId>

        <version>1.0.0.Final</version>

    </dependency>

anyway works

thanks

next step is same like I had week ago it means that process started, first work item called, and first human task called but after this next task is not created, I saw that you Jimmy have the same problem in your new post. I don't know why it is happening. I tought that changes with FakeUserTransaction will solve that problem but I see that not...

[jimmy001]

I am still trying to figure out why this is the case. I can't find the code to trigger the next node.

It is obvious how it works, when you start a new process instance. But when completing a node there seems to be no code to call the necessary method.

I am thankful for any hints.

Maciej,

I am using your fake UserTransaction workaround with jbpm 6.2 running on Wildfly 8.2. My project consists of the rewards CDI example along with your process that uses JPA persistence.  It works fine if I start the process in my @Named jsf backing bean. However, if I move the code into an ejb, I get this error

Any ideas? I've tried setting diferent @Transactional annotations on the EJB method, but still get the same error.

Thanks!
