how to install the jbpm5 to work on mysql database

[kimimo]

I want to install jbpm5 and make it working on mysql database,but I didn't find where to config the database type,please help!

[_yasser]

Hello Kimi,

I had to update  hibernate.cfg.xml, persistence.xml and testDS1-ds.xml in jbpm-installer\db folder, and copy mysql-connector-java-5.1.6-bin.jar  to db/driver folder, you need to run ant install.demo again for these changes to take effect.

I had also to open jbpm-human-task-5.1-SNAPSHOT.jar located in runtime folder and change hibernate settings in persistence.xml

Greetings,

[kimimo]

Hello Yasser,

     Thanks for your reply. I followed your advice and it successfully working on mysql db

I followed same instructions. But the database is not created. When I am starting server I am receiving following exception.

Hi nirav2003,

     I also develop a sample project with Spring, jBPM5 and Drools. For me, I configure in update  hibernate.cfg.xml, persistence.xml and testDS1-ds.xml. And also I have point out my WS-Human Task Server's persistence.xml from runtime/jbpm-human-task-5.0.0.jar. Inside jar, there has also persistence for WS-HT server. I change and point out it like that:

Sorry for the late reply, but still I was trying to make it work. I have configured it as follows:

1.       Hibernate.cfg.xml

     <session-factory>

        <!-- Database connection settings -->
        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="connection.url">jdbc:mysql://192.168.12.99:3306/jbpm_demo?useUnicode=true&amp;characterEncoding=UTF-8</property>
        <!--property name="connection.url">jdbc:h2:file:/NotBackedUp/data/mydb</property-->
        <property name="connection.username">jbpmUser</property>
        <property name="connection.password">jbpm</property>

        <!-- JDBC connection pool (use the built-in) -->
        <property name="connection.pool_size">1</property>

        <!-- SQL dialect -->
        <property name="dialect">org.hibernate.dialect.MySQLInnoDBDialect</property>

        <!-- Enable Hibernate's automatic session context management -->
        <property name="current_session_context_class">thread</property>

        <!-- Disable the second-level cache  -->
        <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>

        <!-- Echo all executed SQL to stdout -->
        <property name="show_sql">false</property>

        <!-- Drop and re-create the database schema on startup? -->
        <property name="hbm2ddl.auto">create</property>

        <mapping resource="AuditLog.hbm.xml"/>

    </session-factory>

2.       Persistence.xml

<persistence-unit name="org.jbpm.persistence.jpa" transaction-type="JTA">

      <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup" />
    </properties>

3.       TestDS1-ds.xml

    <password>jbpm</password>
  </local-tx-datasource>

4.       Persistence.xml in jbpm-human-task-5.1.0.CR1.jar properties changed to

<properties>
      <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLInnoDBDialect"/>
      <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>

      <property name="hibernate.show_sql" value="false" />
    </properties>

After doing all this changes the end result is still same, database in MySql is not created after running install command.

Also, when i am running the startup command i am receiving above error. (The error is due to the database table not found.)

using following softwares:

MySql 5.1

jbpm-5.1.0.CR1-installer.zip

Windows 2008 server.

MySql is installed on different server.

[aungmyozaw]

     Nevermine nirav. As for me,

~ Firstly I configure "jbpm-5.0.0\build.xml",

~ And then, configure "db\persistence.xml, db\hibernate.cfg.xml, db\testDS1-DS.xml",

~ And then, I also changed in "jbpm-5.0.0\lib\jbpm-5.0.0.bin.zip". Extract zip and there are seven jars. I configured the jbpm-human-task-5.0.0.jar like previous describe.

~ And then create a database in MySQL with name "jbpm" that described in persistence.xml.

~ I run and command with Ant "ant install.demo.mysql".

~ And also want to sugguest to reference "http://docs.jboss.org/jbpm/v5.0/userguide/ch02.html"

[nirav2003]

Thanks for the explanation.

It looks like the only difference is in build.xml

Can you share what you change in build.xml? (I am not good with the build tools.)

[nirav2003]

Finally I found the problem.

Anyone using MySql 5 and above needs different dialect for hibernate.

Use MySQL5InnoDBDialect instead of MySQLInnoDBDialect.

Everything is fine after changing the dialect.

Thanks everyone for your contribution. Specially AUNG MYO ZAW.

Hello Everyone,

I am getting an exception when configuring jbpm 5.1 on jboss 5.1 with mysql 5.1.

I have modified hibernate.cfg.xml, persistence.xml, testDS1.xml, jbpm-human-task-5.1.0.Final.jar and I am able to export the jbpm schema in my sql tables.

4 new tables : eventtypes, processinstanceinfo,sessioninfo, workiteminfo got created into the database named jbpm_demo within mysql.

However when i try to open the console i get the above exception.

I think the exception is comming due to modifications required in jbpm-human-task-5.1.0.Final.jar . Did anyone face the similar exception (Exception stack trace @ bottom)

Here is the information from the modified files @ the time of exception:

How come no one mentions the jBPM-ds.xml file in this discussion? Don't we have to change this one too, or is it unused somehow ?

[nirav2003]

If you are using jBPM-ds.xml to create base structure. Yes you need to change. You may skip it by creating base strucrute using provided SQL scripts.

The main problem for me is that my installer zip file, jbpm-5.2.0.Final-installer-full.zip, doesn't contain any sql scripts for mysql.

The documentation in this thread was insufficient to get that version working with mysql. I found out that in the included jboss 7 you need to install the mysql driver as described in http://planet.jboss.org/view/post.seam?post=how_to_create_and_manage_datasources_in_as7. In jboss as 7 apparently the jbpm datasource is defined in standalone.xml, and I'm about sure that a port to mysql cannot be achieved without changing that file too.

Puzzling all pieces together I currently have a 5.2.0 working on mysql, the only remaining problem is that in the demo scenario the workflow diagram always remains in the start state, even when krisv did a self evaluation.

My gut feeling is that 5.2 is not production quality yet today, I'll create a separate post to see what the rest of the world thinks about this ...

Nirav, I am trying to install jbpm-5.3, I have followed steps which need to be change but i can't able to see the database table structure in mysql database.

Regarding "SQL scripts" mentioned by you, i can't able to find it in jbpm-5.3.
