Error initializing process engine in Websphere

rafusaro — Thu, 10 Mar 2011 15:33:53 GMT

I am getting the following messages in Websphere's log when I try to deploy my webapplication. I have created a simple ServletContextListener to initialize and destroy the process engine like the example in the user guide which I added to the web.xml file.[3/9/11 15:31:23:038 CST] 00000032 ProcessEn

<bean id="processEngineConfiguration" class="org.activiti.engine.impl.cfg.StandaloneInMemProcessEngineConfiguration">

update class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration"

pls try it,hope u can fix it!

Thanks for your reply.

I did update the class in the activiti.cfg.xml file to org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration as you recommended.

Unfortunately I am still getting the same error message as before.

I added some code in the listener to get the exception stack trace which follows from the Websphere log.

I wrote a java class that uses the process engine and reads the activiti.cfg.xml file in eclipse. It works but I have not been able to get past this error in a web app I've deployed to Websphere.

Any ideas would be appreciated. Thanks Rick

Thanks for reporting this issue. Spring doesn't allow setters to return values (doesn't conform to java-bean spec) so it'll throw the "Original must be null" exception.
What version of activiti are you using? Since 5.3, the dataBaseType isn't required anymore, it's automatically deducted from the datasource. So this is a workaround for this method.

The method shouldn't return anything, i'll create a JIRA-issue for this…

We were running 5.2 but I upgraded to 5.3.

I changed the database configuration to use a dataSource.

The same error as before is now about the dataSource property instead of the databaseType property.

[size=85][3/15/11 15:26:03:061 CDT] 00000027 SystemOut O processEngine Exception=org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'processEngineConfiguration' defined in resource loaded through InputStream: Initialization of bean failed; nested exception is org.springframework.beans.TypeMismatchException: Failed to convert property value of type [org.apache.commons.dbcp.BasicDataSource] to required type [javax.sql.DataSource] for property 'dataSource'; nested exception is java.lang.IllegalArgumentException: Original must not be null
[/size]

Since the version of Websphere we are running uses Java 1.5 I had to switch to using commons-dbcp 1.3 in order to use the dataSource.

Do you have any suggestions on how to get around this problem?

Thanks Rick

Rick,

What version of Spring are you using?

Re: Error initializing process engine in Websphere

rafusaro — Wed, 16 Mar 2011 21:23:39 GMT

Thanks a lot for helping me troubleshoot these errors. I am trying to integrated Activiti into our web application that we want to use with your workflow and IBM's Lotus Forms product.

Looking at the maven build we were including Spring 2.5.5 so I removed it and added version 3.0.3 and that error appears to be fixed.

I changed the database configuration to use Mysql and manually ran the supplied sql to create tables and loaded security data on the server that runs Websphere and Lotus Forms.

I got an error message about missing property historyLevel so I added the following to the activiti-cfg.xml file.

<bean id="processEngineConfiguration" ….
<property name="historyLevel" value="1" />

I had a string character before changing it to 1 and the error messages was about the value should be an int.

The following is the error I'm getting now:
[size=85][3/16/11 16:04:02:575 CDT] 00000033 SystemOut O processEngine Exception=org.activiti.engine.ActivitiException: Activiti database problem: no historyLevel property specified
at org.activiti.engine.impl.db.DbSqlSession.dbSchemaCheckVersion(DbSqlSession.java:482)
at org.activiti.engine.impl.db.DbSqlSession.performSchemaOperationsProcessEngineBuild(DbSqlSession.java:851)[/size]

I can not find any documentation on what the value should be so I used 1.

I am trapping this error in my ServletContextListener class that is to initialize the process engine.

Can you elaborate on what I need to do in a web app for integrating Activiti's process engine.

Thanks Rick

Re: Error initializing process engine in Websphere

rafusaro — Fri, 18 Mar 2011 20:56:18 GMT

I resolved the "no historyLevel property specified" error by dropping the activiti database and rerunning all the sql scripts in Mysql for creating the activiti database for version 5.3.
