Re: [jboss-user] [jBPM] - Central jBPM (enterprise) with remote access from managing apps

Firstly the console is a generic application and is used for other projects, too and secondly it should be deployable on an application server different from the one jBPM is deployed on. So you could go and try to use the RESTful webservices. Search the forums. There are a couple of posts about it. You could also build your own abstraction layer in form of a webservice. If you search the forums you will also find the effort of somebody trying to create a REST interface for jBPM. Be aware that the RESTful webservice for the console does not implement all the operations offered by the jBPM-API. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/537795#537795] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[jBPM] - Central jBPM (enterprise) with remote access from managing apps

by zecas zecas

zecas zecas [http://community.jboss.org/people/zecas] created the discussion "Central jBPM (enterprise) with remote access from managing apps" To view the discussion, visit: http://community.jboss.org/message/537793#537793 -------------------------------------------------------------- Hi, I'm new to jBPM, and I'm reading a manual plus many guides on the web, and there are some questions that come to my mind. I know I can incorporate jBPM in a web application, standalone application. That is quite awesome and feels good to have such wide options available. But let's look into this specific scenario, and the best practices to implement it: I want to implement severam processes in a company. I want to be able to execute them, and to have a web frontend. Let's imagine that I'll have 1 specific webapp for each process, to make it hard :) . So I can develop each webapp, with included jBPM, and each one will have a database with webapp specific tables, and jBPM specific tables. That is the way I can develop them all. But I'm interested in another approach ... I want ONE instance of jBPM running, with a dedicated database, hibernate config, etc ... I'll deploy ALL enterprise processes in there. Central jBPM processing. Period. Then, I'll develop each webapp, let's say in isolated EARs, and each one will connect to the central jBPM repository and list their processes, start them, signal them, etc ... That central jBPM EAR would be responsible to display the console that, for admin purposes, would allow us (admins) to deploy the process xml and manage process "versions", or check their status, or even display some statistical info. Is there something already available for the job? I mean, an EAR that allows to work with jBPM via Webservice invocations, or remote EJB invocations, to mimic the service api I can use "locally"? Thanks -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/537793#537793] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[JBoss Cache POJO Edition] - Where do I (should I?) set the -javaagent parameter on JBoss startup?

To view the discussion, visit: http://community.jboss.org/message/537789#537789 -------------------------------------------------------------- Hello I'm using the default configuration of JBoss with an application that uses pojo cache. All is well with pojo cache startup, but I get exceptions when trying to attach anything to the cache. Do I have to set the -javaagent:..\lib\jboss-aop.jar option in the %JBOSS_HOME%\bin\run.bat file or is it not required? Or maybe set it somewhere else? How does the pojo cache work with the "all" configuration since the -javaagent is not set? And what about the -Djboss.aop.path=path\to\pojocache-aop.xml? Also set it in run.bat? Cheers Lefteris -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/537789#537789] Start a new discussion in JBoss Cache POJO Edition at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [JBoss Web Services] - Parralel asynchronous calls

by Peter Johnson

Peter Johnson [http://community.jboss.org/people/peterj] replied to the discussion "Parralel asynchronous calls" To view the discussion, visit: http://community.jboss.org/message/537768#537768 -------------------------------------------------------------- That error means that either you are running with too small of a heap or you have a memory leak. What heap size (-Xmx) are you specifying? And are you sure that the JVM is using that much heap? Checking the process memory utilization usually helps here - if you set -Xmx512M and the java process is using less than 100MB of memory, you know it didn't see the -Xmx512M. But if the java process is using around 600MB you kn ow that it did see the setting. If you have a sufficiently large heap, then you need to figure out where the memory leak is. Try setting -XX:+HeapDumpOnOutOfMemoryError. This option causes the JVM to dump the heap to a file which you can then analyze using a tool such as VisualVM. VisualVM will show you which objects occur the most often and which objects are using the most heap space. By the way, "too small of a heap" depends entirely on your application. If you are passing, and dealing with, very large objects then you will need a lot more heap that if you are working with ints, longs and short strings. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/537768#537768] Start a new discussion in JBoss Web Services at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]
