[JBoss jBPM] - Error while deploying Processdefinition thru a servlet
by jbpmIndia
Hi
I am using 'jbpm 3.1.3' on 'JBOSS AS 4.0.5.GA'
I am executing following code in a servlet
| JbpmConfiguration jbpmconfig = JbpmConfiguration.parseXmlString(
| "<jbpm-configuration>" +
|
| // A jbpm-context mechanism separates the jbpm core
| // engine from the services that jbpm uses from
| // the environment.
|
| " <jbpm-context>" +
| " <service name='persistence' " +
| " factory='org.jbpm.persistence.db.DbPersistenceServiceFactory' />" +
| " </jbpm-context>" +
| "<jbpm-context>" +
| "<service name='persistence'>" +
| "<factory>" +
| "<bean class='org.jbpm.persistence.db.DbPersistenceServiceFactory'>" +
| "<field name='isTransactionEnabled'>" +"<false/>" +"</field>" +
| "</bean>" +
| "</factory>" +
| "</service>" +
| "<service name='tx' factory='org.jbpm.tx.TxServiceFactory' />" +
| "<service name='message' factory='org.jbpm.msg.db.DbMessageServiceFactory' />" +
| "<service name='scheduler' factory='org.jbpm.scheduler.db.DbSchedulerServiceFactory' />" +
| "<service name='logging' factory='org.jbpm.logging.db.DbLoggingServiceFactory' />" +
| "<service name='authentication' factory='org.jbpm.security.authentication.DefaultAuthenticationServiceFactory' />" +
| "</jbpm-context>" +
|
|
| // Also all the resource files that are used by jbpm are
| // referenced from the jbpm.cfg.xml
|
| " <string name='resource.hibernate.cfg.xml' " +
| " value='hibernate.cfg.xml' />" +
| " <string name='resource.business.calendar' " +
| " value='org/jbpm/calendar/jbpm.business.calendar.properties' />" +
| " <string name='resource.default.modules' " +
| " value='org/jbpm/graph/def/jbpm.default.modules.properties' />" +
| " <string name='resource.converter' " +
| " value='org/jbpm/db/hibernate/jbpm.converter.properties' />" +
| " <string name='resource.action.types' " +
| " value='org/jbpm/graph/action/action.types.xml' />" +
| " <string name='resource.node.types' " +
| " value='org/jbpm/graph/node/node.types.xml' />" +
| " <string name='resource.varmapping' " +
| " value='org/jbpm/context/exe/jbpm.varmapping.xml' />" +
| "</jbpm-configuration>"
| );
| JbpmContext jbpmContext = jbpmconfig.createJbpmContext();
| ProcessDefinition processDefinition = ProcessDefinition.parseXmlResource("processes/WorkFlowTest/processdefinition.xml");
| jbpmContext.deployProcessDefinition(processDefinition);
In have kept 'processdefinition.xml' under processes/WorkFlowTest under WEB-INF
and I am getting the following error.

[JBoss Seam] - Re: Problems using Authenticator.authenticate()
by appendix
Hi!
Thank you for your response! I really appreciate it.

That's bad :(
I'm facing the situation that the database is counting the login attempts and blocks the account, when an invalid password is provided three times.
How would I deal with the fact, that I don't know how often the Authenticator.authenticate() method is called?
Does this mean, that I can't use the build-in identity component?
Could you explain, why the method could be called multiple times within the same request-response-cycle? I thought, if the action method returns "false" then a simple re-rendering of the page is performed.
Regarding the exceptions, I do have a try/catch(Exception e) in my dbAccess.authenticate() method - nothing is captured there...
Best Regards, Kurt
