[JBoss jBPM] - Re: jbpm with EJBs-->monthly report generation

by kukeltje

Yang, If the jbpm log entries contain the right data, I would use these, no need to duplicate them. Currently jBPM does not have facilities for generating reports.

In other words, how to pass the security information of the EJB enviroments to the jbpm engine? e.g., is it possible to pass Caller Principal of EJB method calls to the jbpm engine methods? what is the recommended way?

[JBoss jBPM] - jbpm with EJBs-->security

by yxyang

Hello >From jbpm user guide, anonymous wrote : | Authentication is the process of knowing on who's behalf the code is running. In case of jBPM this information should be made available from the environment to jBPM. Cause jBPM is always executed in a specific environment like a webapp, an EJB, a swing application or some other environment, it is always the surrounding environment that should perform authentication. | Also from user guide: anonymous wrote : | 11.11.2.1. First terms | | An expression is resolved from left to right. The first-term specifies a User or Group in the identity model. Subsequent terms calculate the next term from the intermediate user or group. | | previous means the task is assigned to the current authenticated actor. This means the actor that performed the previous step in the process. | If i don't want to use jbpm_user, jbpm_group etc database table but using EJB and servlet enviroment to provide securied enviroment, how to make sure current authenticated actor is the principle name of the EJBs? More information is appreciated here.

[JBoss jBPM] - jbpm with EJBs-->monthly report generation

by yxyang

Hello, What is the recommended way to generate monthly report? If using jbpm engine to drive the sales order etc...., what is the recommended way to collect the monthly report needed data? Because external modules are needed to generated monthly report, these modules need to collect data from database. Is it a recommended way to collect data from jbpm log entries? OR using external database to store these project specific data for reporting purpose?

[JBoss Seam] - Interceptor blocks Callback-Methods Destroy and Remove

by bambata

Hi, I have a SFSB with an Interceptor which wraps all methods of this bean and checks if the user rights for this bean do exist. If the rights are present then invocation.proceed() is called. The interceptor works fine, however if the last method with the @end annotation is called, then the method destroy() which is annotated with @destroy and @remove gets not called anymore. The consequence is that the resources for the SFSB don´t get released. Is there a way to solve this problem? many thanks hans View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3963379#3963379 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3963379
