Before we create the schema tasks lets create some packages which willl contain actions and config files.

Create the following packages:\\

{{org.appfuse.jbpm.config}}\\

{{org.appfuse.jbpm.action}}\\

The following files are from the Jbpm Starter Kit (see [IntegratingJBPMIntoAppFuse] for the download link) :-

Copy these files to {{org.appfuse.jbpm.config}}:\\

1. {{jbpm/src/config.files/hibernate.cfg.xml}}\\

2. {{jbpm/src/resources/hsqldb/create.db.hibernate.properties}}\\

3. {{jbpm/src/resources/hsqldb/identity.db.xml}}\\

{{create.db.hibernate.properties}} does require modification . It has to point to the Jbpm datasource (same as the one defined in Part I).

{{{

hibernate.dialect=org.hibernate.dialect.MySQLInnoDBDialect

hibernate.connection.driver_class=com.mysql.jdbc.Driver

hibernate.connection.url=jdbc:mysql://localhost/jbpm?useUnicode=true&characterEncoding=utf-8

hibernate.connection.username=root

hibernate.connection.password=

hibernate.show_sql=true

hibernate.cache.provider_class=org.hibernate.cache.HashtableCacheProvider

}}}

;:%%(color: blue)''You might want to change the cache provider for production usage to a more robust one such as Ecache. If you plan on sticking with this one, ensure that {{dao.compile.classpath}} in {{properties.xml}} contains this reference:''%%

{{{

...

...

</path>

}}}

{{identity.db.xml}} contains users/group/participation data. It can be modified to your liking. More on this later when we delve into creating / assinging tasks in the workflow.

And finally add these targets to your main AppFuse {{build.xml}} file:

{{{

</copy>

</zip>

</target>

<jbpmschema actions="drop"

cfg="src/dao/org/appfuse/jbpm/config/hibernate.cfg.xml"

properties="src/dao/org/appfuse/jbpm/config/create.db.hibernate.properties"/>

<jbpmschema actions="create"

cfg="src/dao/org/appfuse/jbpm/config/hibernate.cfg.xml"

properties="src/dao/org/appfuse/jbpm/config/create.db.hibernate.properties"/>

<deployprocess cfg="src/dao/org/appfuse/jbpm/config/hibernate.cfg.xml"

properties="src/dao/org/appfuse/jbpm/config/create.db.hibernate.properties">

</deployprocess>

<loadidentities file="src/dao/org/appfuse/jbpm/config/identity.db.xml"

cfg="src/dao/org/appfuse/jbpm/config/hibernate.cfg.xml"

properties="src/dao/org/appfuse/jbpm/config/create.db.hibernate.properties"/>

</target>

</target>

}}}

\\

{{build.processes}} is a convenience task to build process defnitions. Multiple definitions can be added.\\

{{declare.jbpm.tasks}} does exactly what it names implies, loads task definitions used in clean_jbpm target.\\

{{clean_jbpm}} refreshes the jbpm db. Which i find myself doing a lot of! It first drops the schema(you will lose all changes, so beware), then creates a new one, then deploys process defintions and finally loads workflow identities(users) into the jbpm database.

Execute __ant clean_jbpm__ and watch the magic happen!
