Trying to use MySQL Database instead of H2 to retrieve Process Info [in AS7]--jbpm-console NOT being deployed
Greetings All,
This has been a very frustrating few days trying to get this to work. In trying to get failed processes restarted, I was not able to retrieve process instance information from the H2 tables which hold the data. I've decided to use another DBMS to which I have access to--MySQL.
I've configured my package to use a MySQL database instead of the default in-memory database to record process info data. I've followed a few examples to get the point where I am now. The main documentation I'm using is
https://zorq.net/b/2011/07/12/adding-a-mysql-datasource-to-jboss-as-7/#comments
+
I have
1.) Downloaded the MySQL driver from dev.mysql.com, and realized after DAYS of trying to get it to work that it was JDBC-4 compliant and it had to be manipulated in order for it to work
2.) Installed the driver as a module by creating the module file in jboss<release>/modules/com/mysql/main:
<module xmlns="urn:jboss:module:1.0" name="com.mysql">
<resources>
<resource-root path="mysql-connector-java-5.1.35-bin_COMPLIANT.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
3.) Defined the datasource in the standalone configuration jboss<release>/standalone/configuration/standalone-full.xml:
<datasources>
<datasource jta="true" jndi-name="java:jboss/datasources/jbpmDS" pool-name="jbpmDS" enabled="true" use-java-context="true" use-ccm="true">
<connection-url>jdbc:mysql://localhost:3306/jbpm6</connection-url>
<driver>mysql</driver>
<security>
<user-name>root</user-name>
<password>pass</password>
</security>
</datasource>
<drivers>
<driver name="mysql" module="com.mysql">
<driver-class>com.mysql.jdbc.Driver</driver-class>
<xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>
</driver>
</drivers>
</datasources>
5.) The JBPM DB has also been created with the scripts provided in jbpm-installer/db/ddl-scripts/mysql. All of the persistence tables seem to be there.
I'm launching AS7 with . jboss<release>/bin/standalone.sh --server-config=standalone-full.xml&
This installation has not been successful and I think this (recurring) exception is preventing my jbpm-console from being launched:
