Act. Explorer Exception: unknown variable type jpa-entity

[n_s_]

Hello,


I'm trying to use a custom process which involves references to custom JPA entities.

As noted in the manual and forum topics http://forums.activiti.org/en/viewtopic.php?f=6&t=2373&start=0
I provided a activity.cfg.xml in which I use my custom JPA Entity Manager Factory:

<?xml version="1.0" encoding="UTF-8"?>

My persistence.xml declares a persistence-unit "myentities" which includes my entities. I'm able to start/control my process within a unit-test / own servlet. So JPA inside the Acitiviti Engine works.


But if I try to access my process within Activiti Explorer I receive an
"ActivitiException: unknown variable type name jpa-entity"

I guess the explorer still uses a custom persistence unit (where is it defined?) which is not aware of my JPA mappings. How can I extend Activiti Explorer so it knows my JPA entities?

Best regards, Nikola

Hi,

You can look at the WEB-INF/applicationContext.xml Spring configuration.
There you can fill-in your JPA context.

Hello,

thanks for the quick reply.
I adjusted the file applicationContext.xml
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
    <property name="driverClassName" value="org.h2.Driver" />
    <property name="url" value="jdbc:h2:tcp://localhost:9092/~/test?autoReconnect=true;create=true" />
    <property name="username" value="Testuser" />
    <property name="password" value="start" />
     <property name="defaultAutoCommit" value="false" />
  </bean>
  <bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
   <property name="dataSource" ref="dataSource" />
   <property name="transactionManager" ref="transactionManager"/>
   <property name="databaseSchemaUpdate" value="true" />
   <property name="jobExecutorActivate" value="true" />
        <property name="customFormTypes">
        <list>
              <ref bean="userFormType"/>
        </list>
        </property>

        <!– Database configurations –>
        <property name="jdbcUrl" value="jdbc:h2:tcp://localhost:9092/~/test"/>
        <property name="jdbcDriver" value="org.h2.Driver"/>
        <property name="jdbcUsername" value="Testuser"/>
        <property name="jdbcPassword" value="start"/>

        <property name="jpaEntityManagerFactory" ref="entityManagerFactory"/>
        <property name="jpaHandleTransaction" value="true"/>
        <property name="jpaCloseEntityManager" value="true"/>

  </bean>
and also adjusted activiti-context.xml, activiti-ui-context.xml. It compiles fine and says it is using my database
[jetty] [DEBUG] org.springframework.jdbc.datasource.SimpleDriverDataSource - Creating new JDBC Driver Connection to [jdbc:h2:tcp://localhost:9092/~/test]but I'm still not able to see my own tables in the Database  within the Explorer.
I should though, right? What am I missing?

Best regards, Nikola
