[JBoss jBPM] - jBPM/jBoss seam performance

by fquimbay

Greetings ... I was reading the JBoss Seam Forum and I saw this post: http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4075312#4075312 I think the correct forum por this question is here, for this reason I again post for any help: anonymous wrote : | Hello, well I'm new using jBPM and here at the company where I work we want to apply it to our system in order to get an organized and ordered navigation scheme for our development. Some of my ex-workpartners whom had worked with this framework have told me that jBPM is excellent, if only if the process isn't small , since they applied it to three/four tasks processes and the response time was slower than without using jBPM. They got a process with three tasks and with jBPM took more than one minute by giving an answer, instead without jBPM, the same procedure took some seconds to give an answer. | | I'd like to know when should I apply jBPM, which are the performance advantages and disadvantages that might affect a system with this framework ?, or is there any pre-study made to measure jBPM and seam performance like http://www.dell.com/downloads/global/power/jbossworld_2006_june_jaffe.pdf? | | What'd it be better for using, the stateful or stateless seam conversational flow or jBPM? | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4075598#4075598 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4075598

[JBoss jBPM] - SchedulerServlet for jbpm 3.2

by akmanocha

I have seen following piece of code used in jBPM with the previous versions (till 3.1) | <servlet> | <servlet-name>SchedulerServlet</servlet-name> | <servlet-class>org.jbpm.scheduler.impl.SchedulerServlet</servlet-class> | <load-on-startup>1</load-on-startup> | </servlet> | <servlet-mapping> | <servlet-name>SchedulerServlet</servlet-name> | <url-pattern>/scheduler</url-pattern> | </servlet-mapping> | but I guess in the jbpm 3.2 the SchedulerServlet invoking thing has been changed. i need to use it through web application is there some other way to access it now, I am using the following service in the jbpm.cfg.xml | <jbpm-context> | <service name="scheduler" factory="org.jbpm.scheduler.ejbtimer.EjbSchedulerServiceFactory" /> | </jbpm-context> | thanks in advance for any pointers View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4075595#4075595 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4075595

[JBoss Seam] - Re: how to conditionally render a row of dataTable

by ellenzhao

I read that article. It seems there's a lot work to do in the infrastructure for adding a simple filtering feature.... Here are small view files in my own project demonstrating how I compose views. Hopefully they are readable enough....the foodCont is the name of a manager backing bean. This file is never directly accessed, but always included in other view files. All my directly-accessed views are started with a verb, shortly describing a use case.

How versioning works , is it the case that if i ammend a process that it will new processes will use the new version and the existing ones use the older one ? 3. In eclipse i deployed to jbpm/upload on port 8080 , if i was using this in a production system how would i control who can deploy ? any help is appreciated View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4075592#4075592 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4075592

atao: haha, I was just drafting my reply when you posted your comment:) Well, my solution is almost identical to yours:) It works very well, thank you very much for the idea! I have the full write-up and modified files here: http://www.digitalsanctuary.com/tech-blog/java/jboss/seam/seam-gen-and-mu... If anyone is interested. I'd love to see this get rolled into the main seam product.

Here is a try i did some time ago with "generate-entities". The idea is to avoid to duplicate the same code in seam-gen/build.xml and in {project_home}/build.xml. It should work for any other target. In the seam-gen/build-scripts/build.xml, add: | <target name="generate-entities" | description="Reverse engineer entities from the database"> | | <ant dir="${seam.home}/seam-gen" target="generate-entities" inheritall="false"> | <property name="project.name" value="${project.name}"/> | <property file="${basedir}/build.properties"/> | <property file="${basedir}/seam-gen.properties"/> | </ant> | | </target> | | | the variable seam.home must be defined in {project_home}/build.properties in seam-gen/build-scripts/build.properties, add: | seam.home = @seamHome@ | | and in seam-gen/build.xml, in filterset "project", add: | <filter token="seamHome" value="${basedir}/.." /> | | the seam-gen/build.properties is copied in {project_home}/seam-gen.properties in seam-gen/build.xml, in target "file-copy", add: | <copy tofile="${project.home}/seam-gen.properties" | file="${basedir}/build.properties"> | <filterset refid="project"/> | </copy> | | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4075590#4075590 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4075590

[JBoss Seam] - Re: Ajax4JSF and s:selectItems

by pdhaigh

hi, actually, the destination on the feedback bean is being correctly set, as indeed is the region (if I add in some outputText fields and get them to be re-rendered it shows the correct values). The problem is just that the selected value in the drop down is not being updated on re-render. I have used this functionality before with no problem, (although that was with textual value in the drop down, rather than seam converted entities) so I'm not sure what exactly is going wrong. cheers phil View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4075589#4075589 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4075589

by damianharvey

I misunderstood what you were trying to do. You aren't trying to re-query regions you are only trying to enable the regions drop-down and (stating the obvious) your problem is that destination in the feedback bean is always null. Is the feedBack bean scoped so that it is maintained over the request? Try scoping it to a conversation and adding a begin-conversation to the page.xml. Also ensure that if you are setting the value of destination in feedbackManager that you are outjecting it. Cheers, Damian.
