[JBoss jBPM] - Re: what is par file? + has anyone used deploy.html in jbpm.

by vtysh

jbpm-starters-kit-3.1.3 has sources of the web application, and uploading servlet works fine with created by plugin archives. Here is a snip of a code: | ZipInputStream zipInputStream = new ZipInputStream(fileItem.getInputStream()); | JbpmContext jbpmContext = JbpmContext.getCurrentJbpmContext(); | ProcessDefinition processDefinition = ProcessDefinition.parseParZipInputStream(zipInputStream); | log.debug("Created a processdefinition : " + processDefinition.getName() ); | jbpmContext.deployProcessDefinition(processDefinition); | zipInputStream.close(); | return "Deployed archive " + processDefinition.getName() + " successfully"; | How you should see, par file is a simple zip archive with some special structure. In the root folder should exist gpd.xml processdefinition.xml processimage.jpg in classes folder you can put necessary classes View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4048603#4048603 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4048603

[Persistence, JBoss/CMP, Hibernate, Database] - Hibernate and XML persistence implementation

by pattchen

Hi, I would like to know if Hibernate can persist objects to XML using the same pojo classes as database persistence classes? In fact,I want to persist/retrieve plain old java objects to/from an xml store which conforms to a given schema. This schema defines foreign key,but objects use aggregation like in hibernate mapping. Let me explain you the problem behind this problem.I've used hibernate 3.2 to persist some objects to a relational database.Now I want to persist/retrieve these objects to/from a xml store which is an instance of a schema. This xml schema is in fact an xml version of the database schema (so foreign and primary keys are also defined). Of course, I don't want to modify existing pojo classes. I just want another persistence(an xml one) implementation. Does Hibernate provide this?If not,is there another solution out there? Thanks.

[Messaging, JMS & JBossMQ] - Monitoring JMS Message Processing

by FlorianusRaetus

Is there a way (using JBoss 4.0.5) to ascertain that all messages from a destination have been processed. Inspecting destination depth via org.jboss.mq.MessageStatistics or org.jboss.mq.server.MessageCounter does not do. It seems that depth becomes zero, after the last message is dispatched (so it has non yet been handled by its subscribers).

[JBoss Seam] - Re: EnumConverter for multi-select lists

by dejan

I have used this code since I needed for my application and it works fine. I also created patch on original EnumConverter class in CVS with some modifications (mostly because Seam CVS version now works with JSF 1.2) and submitted it to JIRA http://jira.jboss.org/jira/browse/JBSEAM-1351 Thanks, Dejan View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4048591#4048591 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4048591

[EJB 3.0] - Merging an extended class from existing superclass

by reuben.helms

Hi all I'm fairly new at the EJB3/JPA stuff, and I'm writing an app that has some legacy data that cant be moved around too much. I have a table and class, Dog (for simplicity) that is populated via another application. This can exist as an instance in its own right. I also have a class SpottedDog that is an extension of Dog. Because I cant play with the Dog table too much, I'm using an additional table for the SpottedDog properties and have tried using SecondaryTable and the table per subclass. The aim is to try and create a SpottedDog from an existing Dog, and keep the unique identifier on the Dog record. I create a new SpottedDog and assign values from the Dog to it in the constructor, and then call em.merge(spottedDog);. However, the Hibernate debugging shows that it tries to search on SpottedDog with a inner join on Dog. Because a SpottedDog record does not exist yet, it assumes that the Dog entry doesnt either, and proceeds to try to insert a Dog entry. This ends up causing an identity insert error, because its trying to do that Dog insert that doesnt need to be done. So, any tips for extending an object to a subclass, where it will recognise that the superclass already exists? For this particular case, it would be nice if the original search was a left outer join on Dog, so that the Dog record would be recognised and only an insert on the SpottedDog would be required. I guess an additional search on Dog instead of the left outer join would do just as well.

[Beginners Corner] - TwoClustersSameNetwork with TCP

by marcdevinci

Hi, I read the excellent wiki page about more clusters in the same network, see http://wiki.jboss.org/wiki/Wiki.jsp?page=TwoClustersSameNetwork The proposed solution use is based on the transport protocol UDP, ... it is possible to get a similare solution based on TCP ? Is also read the page about TCP on the jboss wiki (see http://wiki.jboss.org/wiki/Wiki.jsp?page=JGroupsTCP) but I don't see directly what to change to have two different clusters in the same network. Of course I think the first think is to define to different ClusterName... but then? ... define two different portRange ? for example, the first: <TCP bind_addr="192.168.1.3" start_port="7600" end_port="7800"/> and the second: <TCP bind_addr="192.168.1.4" start_port="7800" end_port="8000"/> Can somebody please help me?

[JBoss jBPM] - Task form cancel button not working

by naseem.k

Hi, I am using jbpm 3.2 GA. I got an exeception when I clicked cancel button of a task form. Task form save button and transition buttons are working perfectly fine only cancel button is not working. Here is the stacktrace... anonymous wrote : javax.el.ELException: /main/task/view.xhtml @204,71 disabled="#{! processBean.hasProcessImage}": java.lang.NullPointerException | at com.sun.facelets.el.TagValueExpression.getValue(TagValueExpression.java:76) | at org.jbpm.webapp.tag.jbpm.ui.Tab.isDisabled(Tab.java:31) | at org.jbpm.webapp.tag.jbpm.ui.TabSet.encodeBegin(TabSet.java:120) | | ............... | | Caused by: java.lang.NullPointerException | at org.jbpm.webapp.bean.ProcessBean.getHasProcessImage(ProcessBean.java:104) | at sun.reflect.GeneratedMethodAccessor220.invoke(Unknown Source) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:585) | | .... | Taskform buttons are as below...  | <tf:saveButton value="Save"/> | <tf:cancelButton value="Cancel"/> | <tf:transitionButton transition="Shipping" value="Shipping"/> | It seems like problem is with rendering of process image when cancel button is clicked. I checked its tld as well, I did not get any tag handler class or tei class for this cancel tag. Functionalities in the Cancel button and SaveButton final clases are same as both extend the same abstract class AbstractTaskFormButton. Is anyone else faced this problem earlier.
