Now my code can run on jbpm 4.4, but I run into a new issue -- no history data are stored in jbpm history tables. I don't have these issues in jbpm 4.2. Is there any new change on history event support in jbpm 4.4? I checked dev guide, could not find any clue. I attached the jbpm.cfg.xml. Wonder if need some changes in this file. Thanks ahead, -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/554045#554045] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [jBPM] - adding a custom service to jbpm.cfg.xml

Whenever you put a <object> tag into jbpm.cfg.xml. Then you could get this service by processEngine.get(ClassName.class). You said it is not work. could you show us more information? Thank you very much. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/554042#554042] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [Beginner's Corner] - The AJP connector, started by default on port 8109

Re: [jboss-user] [Beginner's Corner] - JBoss Supported Java Standards

Richard Lok [http://community.jboss.org/people/thelok617] replied to the discussion "JBoss Supported Java Standards" To view the discussion, visit: http://community.jboss.org/message/554038#554038 -------------------------------------------------------------- Thanks Peter, that is helpful information. I found the page with the list of functionalities that you were referring to: http://java.sun.com/javaee/technologies/javaee5.jsp http://java.sun.com/javaee/technologies/javaee5.jsp Two follow up questions (sorry if they sound stupid): 1) If a certain functionality is listed in Java EE 5, does this mean the functionality must be implemented in the Application Server (and not the JVM)? 2) Taking an example of a specification that exists in Java SE but not in Java EE - let's use JNDI as an example. JNDI has a API for client side and the service layer (SPI) for a provider. Since EE is a superset of SE, does that mean ALL certified EE Application Servers must meet the JNDI SPI provider specifications? Is it safe to assume that since Sun's EE functionality from the above webpage doesn't list anything about JNDI specifications but is it listed in SE? I hope my logic is not wrong, I am still somewhat new to the server side implementations of Java EE. Thanks very much! -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/554038#554038] Start a new discussion in Beginner's Corner at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [Performance Tuning] - Memory consumption 1h after JBoss start

by Ruchir Choudhry

Ruchir Choudhry [http://community.jboss.org/people/ruchirc] replied to the discussion "Memory consumption 1h after JBoss start" To view the discussion, visit: http://community.jboss.org/message/554034#554034 -------------------------------------------------------------- Apprecite your suggestions, It all depends how you want to do it, JVM parameters gives a lot of flexibility to you and there is no one size fits all. Moreover my intent was to help the team get some idea, and not to cut copy the exact thought, Diffrent app requires different type of setup. We ran series of test "Load, noise, bursting, endurace" with multiple appications on single Jboss EAP4.3 with different veriosn of JDK. Results came best with the setup we have explained. We used -XX:MaxTenuringThreshold=0 because it promotes all objects allocated by the application in the young generation, which survive a single GC cycle, directly to the old generation without copying them around between the survivor spaces in the young generation. This setting, when used with CMS collector in the old generation helps in two ways. * The young generation GC does not have to waste its time copying the 10-20% long lived objects multiple times between the survivor spaces, only to finally promote them to the old generation. * Additionally, most of the collection and cleaning work of these objects can be done "concurrently" in the old generation. This behavior leads to additional reduction in GC sequential overhead. http://java.sun.com/developer/technicalArticles/Programming/turbo/ http://java.sun.com/developer/technicalArticles/Programming/turbo/ This setup was also good based on our test scenarios. I guess you are bringing some good points, we will use this in next series of test.Keep giving new Ideas :) Respectfully, Ruchir Choudhry ;) -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/554034#554034] Start a new discussion in Performance Tuning at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [Beginner's Corner] - JBoss Supported Java Standards

Peter Johnson [http://community.jboss.org/people/peterj] replied to the discussion "JBoss Supported Java Standards" To view the discussion, visit: http://community.jboss.org/message/554033#554033 -------------------------------------------------------------- Each release of Java SE includes additional funcitonality that was either part of Java EE or separate functionlaity. For example, web services support was added to Java SE in version 6 (which, if you peruse the forums, you will see caused issues). So those statements indciate when certain functionlaity was provided within Java SE. JBoss AS, on he other hand, track Java EE (previously J2EE) specifications. JBoss AS 4.0.x follows J2EE 1.5, AS 5.x follows Java EE 5 and AS 6 will follow Java EE 6. Sun's (or actually, Oracle's) web page on Java EE describes the individual features/functions/JSRs that are part of any given Java EE release. You will find that some of the functionality overlaps functionality provided in Java SE. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/554033#554033] Start a new discussion in Beginner's Corner at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[Beginner's Corner] - JBoss Supported Java Standards

by Richard Lok

Richard Lok [http://community.jboss.org/people/thelok617] created the discussion "JBoss Supported Java Standards" To view the discussion, visit: http://community.jboss.org/message/554032#554032 -------------------------------------------------------------- Hi guys, Quick clarification - I am researching what Java standards JBoss supports. I am confused by the following statements on JBoss and Sun's sites that I found, as an example: "JNDI is a standard Java API that is bundled with JDK1.3 and higher" "RMI over IIOP is available with the download of the Java 2 platform, Standard Edition, version 1.3 and 1.4." "JAXP Standard - Now implemented via Java SE" Does this mean if I use any JVM to run JBoss, and if I use a Java EE 5 certified version of JBoss Application Server, that JBoss is guaranteed to support those standards? I know JBoss provides functionality for JNDI, RMI, JAXP, etc but I don't see any clear documentation that says JBoss definitely support those standards in their entirety. Thanks. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/554032#554032] Start a new discussion in Beginner's Corner at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]
