Unable to insert new process definitions.

[mihochan]

I am trying to insert process definitions into a MySQL database from a stand-alone application.

The process definitions are good as they install from JBoss. The problem seems to be with the persistence configuration but I can't see what is going wrong.

I can also contact the database to retrieve process definitions.

The jbpm.cfg.xml file;

<jbpm-configuration>
 <jbpm-context>
 <service name='persistence' factory='org.jbpm.persistence.db.DbPersistenceServiceFactory' />
 </jbpm-context>
 <string name="resource.hibernate.cfg.xml" value="jbpm-hibernate.xml" />
</jbpm-configuration>

and the referenced hibernate config file;

<hibernate-configuration>

 <session-factory>

 <!-- jdbc connection properties -->

 <property name="hibernate.cache.use_second_level_cache">false</property>
 <property name="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</property>

 <!-- other hibernate properties -->

 <property name="hibernate.format_sql">true</property>
 <property name="hibernate.use_sql_comments">true</property>

<!-- Enable Hibernate's automatic session context management -->

Any help would be greatly appreciated. Thanks

Found the problem

Turning the following configuration option OFF removes the error.

 <property name="hibernate.use_sql_comments">false</property>

Looks like a bug to me.

Tom,

Googling {hibernate.use_sql_comments mysql}

leads to
http://opensource.atlassian.com/projects/hibernate/browse/HHH-2178

suggesting that a newer MySQL may solve your problem.
(I know you already have a good workaround - I mainly wanted to get this into the forum for future searching by others.)

This did'nt work for me, both for ISASYNC_ and all other bit columns. No matter which version and driver I used on mySQL. What worked was changing all the bit fields in mysql to tinyint(1). This issue is probably due to - http://jira.jboss.com/jira/browse/BPEL-182 or http://jira.jboss.com/jira/browse/JBPM-443

sticking the ALTER script here :...

ALTER TABLE JBPM_PROCESSDEFINITION MODIFY ISTERMINATIONIMPLICIT_ TINYINT(1);
ALTER TABLE JBPM_ACTION MODIFY ISASYNC_ TINYINT(1);
ALTER TABLE JBPM_ACTION MODIFY ISPROPAGATIONALLOWED_ TINYINT(1);
ALTER TABLE JBPM_NODE MODIFY ISASYNC_ TINYINT(1);
ALTER TABLE JBPM_NODE MODIFY ISASYNCEXCL_ TINYINT(1);
ALTER TABLE JBPM_NODE MODIFY CREATETASKS_ TINYINT(1);
ALTER TABLE JBPM_NODE MODIFY ENDTASKS_ TINYINT(1);
ALTER TABLE JBPM_PROCESSINSTANCE MODIFY ISSUSPENDED_ TINYINT(1);
ALTER TABLE JBPM_TASK MODIFY ISBLOCKING_ TINYINT(1);
ALTER TABLE JBPM_TASK MODIFY ISSIGNALLING_ TINYINT(1);
ALTER TABLE JBPM_TASKINSTANCE MODIFY ISCANCELLED_ TINYINT(1);
ALTER TABLE JBPM_TASKINSTANCE MODIFY ISSUSPENDED_ TINYINT(1);
ALTER TABLE JBPM_TASKINSTANCE MODIFY ISOPEN_ TINYINT(1);
ALTER TABLE JBPM_TASKINSTANCE MODIFY ISSIGNALLING_ TINYINT(1);
ALTER TABLE JBPM_TASKINSTANCE MODIFY ISBLOCKING_ TINYINT(1);
