Hi,

I am trying to implement jbpm workflow in my vaadin project. Can anybody please help me to embed it in liferay.

Hi Abhiram,

Let's say that nobody have a specific example about Liferay, Vaadin and jBPM, so in order for us to help you, you will need to be more concrete, about what kind of issues are you facing. Did you add the jBPM dependencies to your project? Did you tried to run a process? What are the errors? Those kind of things will help us to help you

Regards

Hi Mauricio,

     I am implementing jbpm in liferay vaadin. I am refering the example given by Maciej Swiderski as test-spring-ht-jta.zipMaciej Swiderski  

In pom.xml I am adding these inside <properties>

     <!--Added for JBPM-->

          <jbpm.version>6.0.0.Final</jbpm.version>

In pom.xml I am adding these inside <dependencies>

<!--Added for JBPM-->

         <dependency>

            <groupId>org.jbpm</groupId>

            <artifactId>jbpm-test</artifactId>

            <version>${jbpm.version}</version>

        </dependency>

        <dependency>

            <groupId>org.kie</groupId>

            <artifactId>kie-spring</artifactId>

            <version>${jbpm.version}</version>

        </dependency>

        <dependency>

            <groupId>commons-logging</groupId>

            <artifactId>commons-logging</artifactId>

            <version>1.1.1</version>

        </dependency>

        <dependency>

            <groupId>org.springframework</groupId>

            <artifactId>spring-orm</artifactId>

            <version>3.0.7.RELEASE</version>

        </dependency>  

  In pom.xml I am adding these inside <repositories>

            <!--Added for JBPM-->

        <repository>

      <id>jboss-public-repository-group</id>

      <name>JBoss Public Repository Group</name>

      <url>http://repository.jboss.org/nexus/content/groups/public/</url>

      <releases>

        <updatePolicy>never</updatePolicy>

      </releases>

      <snapshots>

        <updatePolicy>daily</updatePolicy>

      </snapshots>

    </repository>

I copied your kmodule-spring.xml to my META-INF folder

But it is showing the following error when I am deploying in liferay Jboss server
