doboss [https://community.jboss.org/people/doboss] created the document: "Installing JBPM 5.3 on JBoss AS 5.1 and changing DB" To view the document, visit: https://community.jboss.org/docs/DOC-18580 -------------------------------------------------------------- A few days ago I tried to get JBPM 5.3 installed into JBoss AS 5.1 using PostgreSQL (without Eclipse) via the jbpm-installer. I had some trouble, but after some customizations, I have been able to get it installed and running. Some of the information came right out of the documentation, some came from community posts, and some I figured out through trial and error. I figured this all out, then wrote it down, and did it again to verify which things needed to be done. Hopefully I successfully captured all the steps here. I used headings and fonts to try to make this easy to follow. I tried to proof this post real quick as well, but I am thin on time, so I apologies for any mistakes I made. With a bit more time, I suspect these steps could be trimmed down to only the necessary steps, as I may have changed which had no effect on the installation. :| Hopefully this post will help others at least get to this point. :) h2. My configuration: Ubuntu 12.04 java version "1.6.0_24" OpenJDK Runtime Environment (IcedTea6 1.11.1) (6b24-1.11.1-4ubuntu3) OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode) JBoss 5.1.0GA PostgreSQL 9.1.4 on x86_64 h2. Preparation h3. Get the installer: The first thing I did was download the jbpm-installer and unzip it into ~/Downloads/jbpm-installer/, and this is the directory/path I will use for the rest of this post. h3. Save some download time: If you are like me, you probably already have a copy of the JBoss distribution sititng around, and rather than having the installation script download it again, I copied it into the installer's lib folder and made a soft link with the name the installer was expecting.  (This step is not critical, just a way to save a bit of time.) cd ~/Downloads/jbpm-installer/ cp ~/Downloads/jboss-5.1.0.GA.zip lib/ ln -s jboss-5.1.0.GA.zip jboss-as-5.1.0.GA.zip # This makes a link with a name of what the installer is expecting h3. Prepare the JBoss installation directory: You will need to setup a JBoss installation directory for the installer to install into. For the rest of the post, I use "path-to-jboss" as this location. cd /path-to-jboss/ unzip ~/Downloads/jbpm-installer/lib/jboss-5.1.0.GA.zip h3. Copy DB drivers into installer: If you are going to use a DB other than the default H2 db, you will need to place the drivers where the installer can find them. cp ~/Downloads/postgresql-9.1-901.jdbc4.jar ~/Downloads/jbpm-installer/lib/ h3. Create the JBPM schema: You will need to create the jbpm schema/database for JBPM to use. I use jbpm5 in this post. h2. Configuration h3. Update build.properties: Next you will need to edit ~/Downloads/jbpm-installer/build.properties h4. Drools Guvnor version: # (Drools guvnor which works with JBoss AS 5.1) drools.guvnor.version=5.3.1.Final drools.guvnor.url=https://repository.jboss.org/nexus/content/repositories... h4. Designer version: Update the properties to use the correct version of the designer for AS 5. I changed the URL to a specific server because it looked like the installer got stuck when redirected so that part may not be necessary. designer.version=2.2.Final-jboss #designer.url=http://sourceforge.net/projects/jbpm/files/designer/designer-2.2/ designer.url=http://iweb.dl.sourceforge.net/project/jbpm/designer/designe... h4. JBoss Home and version: Uncomment/update the jboss.xxxx properties: jboss.server.version=${jboss.server.version.5} jboss.home=/path-to-jboss/jboss-5.1.0.GA jboss.download.url=http://downloads.sourceforge.net/jboss/jboss-${jboss.s... jboss.server.configuration=default jboss.server.deploy.dir=${jboss.home}/server/${jboss.server.configuration}/deploy jboss.server.data.dir=${jboss.home}/server/${jboss.server.configuration}/data/ jboss.clean.repository=true h3. Update build.xml Edit ~/Downloads/jbpm-installer/build.xml to reflect the correct DB driver: Change <property name="db.driver.jar.name" value="mysql-connector-java.jar"/> to <property name="db.driver.jar.name" value="postgresql-9.1-901.jdbc4.jar"/> h3. Database specific files: There are several files which need to be updated for JBoss AS 5 as well as for your specific DB dialect and configurations. h4. Edit db/persistence.xml: First edit ~/Downloads/jbpm-installer/db/persistence.xml h5. Change the dialect and set DB specific configurations: I updated/added the follwing to the <properties> section: <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/> <property name="hibernate.default_schema" value="jbpm5"/> h5. Use AS5 transaction manager: You will need to comment out the AS7 section and comment in the AS5 section:    <!-- for AS7 -->    <!-- <property name="hibernate.transaction.manager_lookup_class" value="org.jbpm.integration.console.JBPMTransactionManager" /> -->    <!-- for AS5 -->    <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup" /> h5. Whole file: This is what my final file looked like: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <persistence version="1.0"              xsi:schemaLocation="http://java.sun.com/xml/ns/persistence                                  http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd                                  http://java.sun.com/xml/ns/persistence/orm                                  http://java.sun.com/xml/ns/persistence/orm_1_0.xsd"              xmlns:orm="http://java.sun.com/xml/ns/persistence/orm"              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"              xmlns="http://java.sun.com/xml/ns/persistence">   <persistence-unit name="org.jbpm.persistence.jpa" transaction-type="JTA">     <provider>org.hibernate.ejb.HibernatePersistence</provider>     <jta-data-source>java:jboss/datasources/jbpmDS</jta-data-source>     <mapping-file>META-INF/JBPMorm.xml</mapping-file>     <mapping-file>META-INF/ProcessInstanceInfo.hbm.xml</mapping-file>     <class>org.jbpm.persistence.processinstance.ProcessInstanceInfo</class>     <class>org.drools.persistence.info.SessionInfo</class>     <class>org.drools.persistence.info.WorkItemInfo</class>     <class>org.jbpm.process.audit.ProcessInstanceLog</class>     <class>org.jbpm.process.audit.NodeInstanceLog</class>     <class>org.jbpm.process.audit.VariableInstanceLog</class>     <properties>       <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/>       <property name="hibernate.default_schema" value="jbpm5"/>       <property name="hibernate.max_fetch_depth" value="3"/>       <!-- hbm2ddl.auto MUST BE update! The console will otherwise overwrite the schema with each new thread -->       <property name="hibernate.hbm2ddl.auto" value="update" />       <property name="hibernate.show_sql" value="false" />       <!-- for AS7 -->       <!-- <property name="hibernate.transaction.manager_lookup_class" value="org.jbpm.integration.console.JBPMTransactionManager" /> -->       <!-- for AS5 -->       <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup" />     </properties>   </persistence-unit> </persistence> h4. Update db/persistence-as5.xml: Most of my problems came from things related to the DB, and it was unclear to me which files were being used/ignored, so for simplicity, I just copied persistence.xml on top of persistence-as5.xml. cp ~/Downloads/jbpm-installer/db/persistence.xml ~/Downloads/jbpm-installer/db/persistence-as5.xml h4. Update task-service META-INF/persistence.xml: Somewhere in the documentation, I read that task-service/resources/META-INF/persistence.xml must be updated. Even though I updated it, I don't think it was used for the installation, and I had to manually copy the file into the deploy directory (covered later in the post.) But go ahead and edit it here, this way you have it somewhere outside of the JBoss install in case you need it again. First edit ~/Downloads/jbpm-installer/task-service/resources/META-INF/persistence.xml You will need to add the <jta-data-source> section as well as configure the <properties> section: ... <persistence-unit name="org.jbpm.task">   <provider>org.hibernate.ejb.HibernatePersistence</provider> *  <jta-data-source>java:jboss/datasources/jbpmDS</jta-data-source>*   <mapping-file>META-INF/Taskorm.xml</mapping-file> ... <properties>   <property name="hibernate.dialect" value="org.hibernate.dialect.*PostgreSQLDialect*"/> *  <property name="hibernate.default_schema" value="jbpm5"/>* *  <property name="hibernate.connection.driver_class" value="org.postgresql.Driver"/>* *  <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup" />*   <property name="hibernate.connection.username" value="*some_username*"/>   <property name="hibernate.connection.password" value="*some_password*"/> </properties> ... h4. Update task-service war/persistence.xml: When things were not working because of problems talking to the DB, I found another persistence.xml file which I also updated. I changed the dialect, added the default_schema, and commented in the correct transaction.manager_lookup_class for AS5. Again, I'm not sure if it was actually picked up and used. Now edit ~/Downloads/jbpm-installer/task-service/resources/war/persistence.xml    <properties>       <property name="hibernate.dialect" value="org.hibernate.dialect.*PostgreSQLDialect*"/> *      <property name="hibernate.default_schema" value="jbpm5"/>*       <property name="hibernate.max_fetch_depth" value="3"/>       <property name="hibernate.hbm2ddl.auto" value="create" />       <property name="hibernate.show_sql" value="false" />       <!-- for AS7 --> *      <!--* <property name="hibernate.transaction.manager_lookup_class" value="org.jbpm.integration.console.JBPMTransactionManager" /> *-->*       <!-- for AS5 --> *      <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup" />*     </properties> h3. Update the datasource: Update ~/Downloads/jbpm-installer/db/jBPM-ds.xml as needed. (Remember to change the driver)   <connection-url>jdbc:postgresql://some_host:5432/some_db_name</connection-url>   <driver-class>org.postgresql.Driver</driver-class>   <user-name>some_username</user-name>   <password>some_password</password> h2. Installation Okay, this part was easy. From inside the jbpm-installer/ directory just run:    ant install.demo.noeclipse h2. Tweaking Once everything was installed, I had a lot of errors when trying to start JBoss, so I had to tweak some of the stuff post install. h3. Remove the form builder: For whatever reason, the form builder would not deploy and gave me this error: [org.jboss.kernel.plugins.dependency.AbstractKernelController] (main) Error installing to Real: name=vfszip:/path-to-jboss/jboss-5.1.0.GA/server /default/deploy/jbpm-form-builder.war/ state=PreReal mode=Manual requiredState=Real org.jboss.deployers.spi.DeploymentException: Error deploying: vfszip:/path-to-jboss/jboss-5.1.0.GA/server/default/deploy/jbpm-form-builder.war/ Since I'm probably not going to use the form builder, I just removed it. I thought maybe the war got corrupted, but I tried the install multiple times with the same error. If you have found a way to make this work, please add to this thread so others can get it working. :) rm path-to-jboss/jboss-5.1.GA/server/default/deploy/jbpm-form-builder.war h3. Fix JBPM console: Out of the box, I got this error when trying to start JBoss: [org.jboss.kernel.plugins.dependency.AbstractKernelController] (main) Error installing to Start: name=persistence.unit:unitName=#org.jbpm.persistence.jpa state=Create org.hibernate.DuplicateMappingException: Duplicate collection role mapping org.jbpm.persistence.processinstance.ProcessInstanceInfo.eventTypes Following this thread: https://community.jboss.org/message/739278 (https://community.jboss.org/message/739278#739278) I was able to fix the problem by renaming ProcessInstanceInfo.hbm.xml. I exploded the war, and made the necessary updates: cd path-to-jboss/jboss-5.1.GA/server/default/deploy/ # Because you can't have a dir with the same name as a file, I do the following 4 steps. mkdir tmp mv jbpm-gwt-console-server.war tmp mv tmp jbpm-gwt-console-server.war cd tmp jbpm-gwt-console-server.war unzip jbpm-gwt-console-server.war # Expload the war mv jbpm-gwt-console-server.war jbpm-gwt-console-server.orig # You could delete the original instead... cd WEB-INF/classes/META-INF/ mv ProcessInstanceInfo.hbm.xml ProcessInstanceInfo.orig # You could removed this file instead... h3. Fix human task war: I also had errors from the human-task war when starting JBoss: Error 1: [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/jbpm-human-task-war]] (main) StandardWrapper.Throwable javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: could not execute query Error 2: [org.jboss.kernel.plugins.dependency.AbstractKernelController] (main) Error installing to Start: name=persistence.unit:unitName=#org.jbpm.task state=Create java.lang.RuntimeException: Specification violation [EJB3 JPA 6.2.1.2] - You have not defined a jta-data-source for a JTA enabled persistence context named: org.jbpm.task Error 3: [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/jbpm-human-task-war]] (main) StandardWrapper.Throwable java.lang.ClassCastException: org.jboss.tm.usertx.client.ServerVMClientUserTransaction cannot be cast to javax.transaction.UserTransaction Error #1 and #2 are due to a persistence.xml which is not setup for my configuration. Error #3 is because of conflicting classes in jta-1.1.jar which is inside the war. So I exploded the war and made the changes: cd path-to-jboss/jboss-5.1.GA/server/default/deploy/ mkdir tmp mv jbpm-human-task-war.war tmp mv tmp jbpm-human-task-war.war cd jbpm-human-task-war.war unzip jbpm-human-task-war.war mv jbpm-human-task-war.war jbpm-human-task-war.orig cp ~/Downloads/jbpm-installer/task-service/resources/META-INF/persistence.xml WEB-INF/classes/META-INF/ # Fixes 1 and 2 rm WEB-INF/lib/jta-1.1.jar # Fix 3 h2. Start JBoss After all this, I started JBoss with the ant task. (You could probably just start it from the bin dir.) cd ~/Downloads/jbpm-installer/ ant start.demo.noeclipse When all was said and done, I was able to start jboss, user the jbpm-console, guvnor, and designer.
