[jBPM] - Performance issues with 4.3

by Christian Moser

Christian Moser [http://community.jboss.org/people/Krossi] created the discussion "Performance issues with 4.3" To view the discussion, visit: http://community.jboss.org/message/534379#534379 -------------------------------------------------------------- Hi! I'm comparing 3.2.6 and 4.x (currently 4.3). I have just installed both versions with standard settings and tried to run an equal process. My problem is that my simple performance measurements showed a bad result for version 4.3. The new jBPM took longer than expected. It needed 2 times longer than the old version (~80 ms per execution vs. ~25 ms). I don't know what I did wrong (probably the configuration is bad). Can someone take a look? Thanks for your reply -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/534379#534379] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Please find uploaded the datasource file that is used by JBoss Messaging, this uses a normal datasource. I have also uploaded my oracle-persistence-service.xml (from the directory jboss-messaging.sar) so that you verify that JBoss Messaging is indeed using this normal datasource.

Re: [jboss-user] [jBPM] - Problems with usage python language in jpdl.xml

Huisheng Xu [http://community.jboss.org/people/rebody] replied to the discussion "Problems with usage python language in jpdl.xml" To view the discussion, visit: http://community.jboss.org/message/534370#534370 -------------------------------------------------------------- Now jBPM 4 could support JUEL, beanshell and groovy, If you want to use python in jpdl.xml, you should create a new ScriptEngineFactory, may be PythonScriptEngineFactory and put it into <script-manager>. The default <script-manager> configuration is as following: <?xml version="1.0" encoding="UTF-8"?> <jbpm-configuration> <process-engine-context> <script-manager default-expression-language="juel" default-script-language="juel"> <script-language name="juel" factory="org.jbpm.pvm.internal.script.JuelScriptEngineFactory" /> <script-language name="bsh" factory="org.jbpm.pvm.internal.script.BshScriptEngineFactory" /> <script-language name="groovy" factory="org.jbpm.pvm.internal.script.GroovyScriptEngineFactory" /> </script-manager> </process-engine-context> </jbpm-configuration> -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/534370#534370] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [jBPM] - How to limit size of jBPM tables : jbpm4_variable and jbpm4_lob ?

by Huisheng Xu

Huisheng Xu [http://community.jboss.org/people/rebody] replied to the discussion "How to limit size of jBPM tables : jbpm4_variable and jbpm4_lob ?" To view the discussion, visit: http://community.jboss.org/message/534368#534368 -------------------------------------------------------------- Because jBPM 4 could not save history variable, when a process instance end, the relative process variable of this process instance will be delete from Database. So do not worry about jbpm4_variable. JBPM4_LOB is used to store both process variable and the resource of deployment, e.g. the XML content of process definition, the PNG image file of process definition. If you delete them, some error may occur. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/534368#534368] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [jBPM] - Alert Capability

by Maciej Swiderski

Maciej Swiderski [http://community.jboss.org/people/swiderski.maciej] replied to the discussion "Alert Capability" To view the discussion, visit: http://community.jboss.org/message/534364#534364 -------------------------------------------------------------- Hi, it depends what you mean by alerts?! jBPM has a concept of event listeners that could be used for some sort of alerting, but it is up to you as developer to include it in your process definition. You could take a look at user guide, section that covers event listeners for more details. http://docs.jboss.com/jbpm/v4/userguide/html_single/#events http://docs.jboss.com/jbpm/v4/userguide/html_single/#events In addition, for human tasks jBPM provides two other capabilities: - notification - sends an email (by default) when task is assigned to a given user - reminder - sends an email (by default) based on time expiration events to a user assigned to a task Types of alerts can be freely coded since all event listeners are java.

[Javassist] - Saving proxy classes and using them in Android

by Eric H

Eric H [http://community.jboss.org/people/EricJava] created the discussion "Saving proxy classes and using them in Android" To view the discussion, visit: http://community.jboss.org/message/534357#534357 -------------------------------------------------------------- I am new to the wonderful world of Javassist, and I now have a question: I have used the very easy and convenient ProxyFactory in the usual way: {code} final ProxyFactory proxyFactory = new ProxyFactory(); proxyFactory.writeDirectory = "/tmp"; proxyFactory.setSuperclass(Invoice.class); final MethodHandler methodHandler = new MethodHandler() { public Object invoke(Object self, Method m, Method proceed, Object[] args) throws Throwable { System.out.println("Name: " + m.getName()); return proceed.invoke(self, args); // execute the original method. } }; proxyFactory.setFilter(new MethodFilter() { public boolean isHandled(Method m) { // ignore finalize() return !m.getName().equals("finalize"); } }); final Class klass = proxyFactory.createClass(); Invoice invoice = (Invoice) klass.newInstance(); ((ProxyObject) invoice).setHandler(methodHandler); {code} That works great. When I call methods on the invoice object there, I immediately see that my MethodHandler is invoked. Super-cool! Also, it does one more thing: it saves a new class file, with a name like Invoice_$$_javassist_0.class . What I would like to do is be able to use that generated class, without needing to have the bytecode present. The reason for this is I want to use it within Android, and Android doesn't use regular class files. If I can use the ProxyFactory to write out the class files, then I can build my Android DEX files using those class files. But I don't know how to load or make use of the generated files like Invoice_$$_javassist_0.class. Does my question make sense? I assume that ProxyFactory is able to save those class files for a good reason, but I can't find out how to make use of them. Thanks -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/534357#534357] Start a new discussion in Javassist at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]
