[jBPM] - JBPM5.4 Final, Cannot use space in Human Task Name, Designer Problem or Not Possible in BPMN2 ?

by Thomas Setiabudi

Thomas Setiabudi [https://community.jboss.org/people/thomas.setiabudi] created the discussion "JBPM5.4 Final, Cannot use space in Human Task Name, Designer Problem or Not Possible in BPMN2 ?" To view the discussion, visit: https://community.jboss.org/message/827484#827484 -------------------------------------------------------------- Hi, I use JBPM5.4.Final Full Installer and the web Designer that comes with it. I noticed that we cannot have empty space in our human task name, for example task name "My Task" will be modified to "MyTask" Is the definition of BPMN prevents this? or is it just because of the designer?

I therefore presume there is an issue in your adapter?

Before I know this solution, I used to cast processInstance to org.jbpm.workflow.instance.WorkflowProcessInstance. Map<String, Object> varMap = new HashMap<String, Object>(); varMap.put("variable", "test"); org.drools.runtime.process.ProcessInstance processInstance = ksession.createProcessInstance( processId, varMap); org.jbpm.workflow.instance.WorkflowProcessInstance workflowProcessInstance = (org.jbpm.workflow.instance.WorkflowProcessInstance) processInstance; String varValue = (String) workflowProcessInstance.getVariable("variable"); Assert.assertEquals("test", varValue); -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/827594#827594] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[JBoss Tools] - Building JBoss Tools Documentation

by Nick Boldt

Nick Boldt [https://community.jboss.org/people/nickboldt] modified the document: "Building JBoss Tools Documentation" To view the document, visit: https://community.jboss.org/docs/DOC-13341 -------------------------------------------------------------- *This document is out of date. See https://github.com/jbosstools/jbosstools-devdoc/blob/master/building/buil... https://github.com/jbosstools/jbosstools-devdoc/blob/master/building/buil... You can download a folder with a plug-in either from a Anonymous SVN (http://anonsvn.jboss.org/repos/jbosstools) or a Committer SVN (https://svn.jboss.org/repos/jbosstools) ( if you have commiter rights) repositories . In the plug-in's folder you will find a directory with documentation.This instruction explains how you can build the documentation. h3. Prerequisites: Ensure you have the Maven building tool Ensure the Nexus repository and profile as defined here: https://community.jboss.org/docs/DOC-15170 http://community.jboss.org/wiki/MavenGettingStarted-Developers are in your *+settings.xml+* file, located in your *%M2_HOME%/conf/* or *%USER_HOME%/.m2/* folder. These settings are required in order to obtain the necessary jDocbook plug-ins that are required to build the JBoss Tools documentation h3. Building Steps So, you checked out the plug-in for which you want to build documentation and the documentation folder. And now you can proceed to building the documentation. 1.Find the +*pom.xml*+ file, that is responsible for building the documentation, in the plug-in folder you downloaded. Normally it’s located in “/docs/reference”. 2.Run *mvn clean install* command in the folder with *+pom.xml+* to start building the documentation. (nightly build docs are build by default) Example: user@user-desktop:/home/user/trunk/seam/docs/reference$ mvn clean install 3.If everything is configured correctly you will see a “BUILD SUCCESSFUL” message. You will also see a generated *+target+* folder that contains the built documentation. Example: To open the HTML version of the “Seam Dev Tools Reference Guide” guide you need to proceed to user@user-desktop:/home/user/trunk/seam/docs/seam/docs/reference/target/docbook/publish/en-US/html_single and open index.html file. h3. Documentation Profiles There are 3 profiles that you can build documentation with: *release* builds release documentation with “new” or “updated” markers next to the corresponding chapters and sections titles *releaseJBDS* builds release documentation with Jboss.com styles for commercial products > Remember to redeploy "jbosstools-jdocbook-style" and "jbosstools-docbook-xslt" if it have been changed. > In order to redeploy you should run 'mvn deploy' from the corresponding directory. You should also have the apropriate credentials to deploy to the http://snapshots.jboss.org/maven2 *diffmk* builds documentation with markers highlighting changes comparing to the previous release version and sets “new” or “updated” markers next to the corresponding chapters and sections titles.*Note:* Please make sure that you have the master_output.xml file (normally the file can be found in \pluginName\docs\reference\en\) as a new guide may not have such file since there's nothing to compare with. This command launches building documentation with a profile. mvn install -Pprofile_name By default, with no profile specified, Nightly Build docs are generated. In order to build all the guide from one place you need to have JBoss Tools trunk checked out then cd to JBoss_tools_trunk/documentation/jbds-docs/ to build JBDS guides with jboss.com styles or to JBoss_tools_trunk/documentation/jboss-tools-docs to build JBoss Tools guides. and run mvn assembly:assembly You can optionally use a profile in this command. mvn assembly:assembly -Pprofile_name -------------------------------------------------------------- Comment by going to Community [https://community.jboss.org/docs/DOC-13341] Create a new document in JBoss Tools at Community [https://community.jboss.org/choose-container!input.jspa?contentType=102&c...]

[Performance Tuning] - Monitoring Servlets and JDBC

by florentine

florentine [https://community.jboss.org/people/florentine] created the discussion "Monitoring Servlets and JDBC" To view the discussion, visit: https://community.jboss.org/message/818357#818357 -------------------------------------------------------------- Hello, I'm new to JBoss and I am trying to get some measurement data for a research project. I am running JBoss 4.2.2.GA and I'm trying to understand how I can measure how much time Jboss takes to respond to a servlet request. In particular, I would like to measure the following: 1. overhead time for JBoss handling the request/response. 2. computation time for the execution of the servlet itself 3. time spent waiting for the database query. I'm using a Hibernate/JDBC architecture. I saw that the web-console is giving some measures like the overall aggregated processing time and the number of requests, but I couldn't find anything about the connection to the db. Thanks a lot for any help and/or suggestion!

[JBoss Portal] - Facing Connection leak ( INACTIVE State) Problem - Jboss Portal 2.7.2

by Asheesh Patel

Asheesh Patel [https://community.jboss.org/people/asheesh.patel] created the discussion "Facing Connection leak ( INACTIVE State) Problem - Jboss Portal 2.7.2" To view the discussion, visit: https://community.jboss.org/message/827547#827547 -------------------------------------------------------------- Hi All, I am seeing there are many connection in 'INACTIVE' state and are present for more than 12-15 hours. Most of the sessions (around 90%) have executed the below query to JBP_INSTANCE_PER_USER table before moving to inactive state Checked from last query executed from v$session table and prev_sql_id [org.hibernate.SQL] select persistent0_.PK as PK6_0_, persistent0_.INSTANCE_PK as INSTANCE2_6_0_, persistent0_.SER_STATE as SER3_6_0_, persistent0_.USER_ID as USER4_6_0_, persistent0_.PORTLET_REF as PORTLET5_6_0_ from JBP_INSTANCE_PER_USER persistent0_ where persistent0_.INSTANCE_PK=? and persistent0_.USER_ID=? The open connection count is reaching to DB threshold value and the inactive sessions are not getting utilized for serving the new request and DB is creating the new connection. Also I have found the PortalDS connection is running out of connection while checking from JMX console. The in-use connection is touching the maximum connection count and available connection count to zero. We are using below environment for our application: *Application server:* Jboss Portal Application 2.7.2 *OS:* Linux I also did the code review for connection leak, but seems the above query is getting executed by Jboss internally while user logs-in to application portal. Can anyone please help me out, if encountered the similar problem in Jboss portal application server. Let me know if need more information for issue. Thanks, Asheesh Patel -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/827547#827547] Start a new discussion in JBoss Portal at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]
