Tips from Sony Thomas

Fundamentally, the JBoss architecture consists of the JMX MBean server, the microkernel, and a set of pluggable component services - the MBeans. The JBoss Application Server ships with three different server configurations. Within the <JBoss_Home>/server directory, you will find three subdirectories: minimal, default and all. The default configuration is the one used if you don’t specify another one when starting up the server. If you want to know which services are configured in each of these instances, look at the jboss-service.xml file in the <JBoss_Home>/server/<instance-name>/conf/ directory and also the configuration files in the <JBoss_Home>/server/<instance-name>/deploy directory. JBoss 4.0 features an embedded Apache Tomcat 5.5 servlet container. conf --> The conf directory contains the jboss-service.xml bootstrap descriptor file for a given server configuration. This has the jboss-log4j.xml file which configures the Apach...

Following are the different options in JBoss to take the thread dump. 1. Using JBoss jmx-console :    Got to http://localhost:8080/jmx-console  and search for the mbean " serverInfo " and click on that link. Click the  invoke mbean operation under listThreaddump() method. This will give you the current snapshot of threads which are running in your JBoss jvm. 2. By using twiddle :   In the commnad promt go to <JBOSS-HOME>/bin and run the command  twiddle.bat invoke "jboss.system:type=ServerInfo" listThreadDump > threadDump.html  and you could find the threadDump.html with the JBoss thread dump. 3. Using "Interrupt" signal :  Use kill -3 <process-id> to generate thread dump. You will find the thread dumps in server logs.

To configure an SSL port with keystore , check the following steps: 1. Generate the keystore with the following command ( using the java keytool command) keytool -genkey -alias tomcat -keyalg RSA -keystore NAME_OF_KEYSTORE -validity NUMBER_OF_DAYS ( For more details check the url http://download.oracle.com/javase/1.5.0/docs/tooldocs/windows/keytool.html ) 2. Copy the file into the jboss/server/<NAME>/conf/ directory 3. Edit the server.xml in the following path JBoss version 4.0.4 = jboss/server/<NAME>/deploy/jbossweb-tomcat55.sar/ JBoss version 4.2.2 = jboss/server/<NAME>/deploy/jboss-web.deployer/ 4. For JBOSS 4.0.4 the SSL-connector should be configured like: <!– SSL/TLS Connector configuration using the admin devl guide keystore     –> <Connector port=”THE_PORT_YOU_LIKE” address=”${jboss.bind.address}” maxThreads=”100? strategy=”ms” maxHttpHeaderSize=”8192? emptySessionPath=”true” scheme=”https” secure=”true” clientAuth=”false” ...

To change the default HTTP port 8080, you need to edit the “jboss-service.xml” (<jboss>\server\<application>\conf\jboss-service.xml). In your “jboss-service.xml” ,search for the mbean ServiceBindingManager. It will be commented by default. You can uncomment it. It is referring to a sample xml port binding file in the example folder ( ${jboss.home.url}/docs/examples/binding-manager/sample-bindings.xml ). You can either use this xml or copy it to another location and give that path in your “jboss-service.xml”. In the sample-bindings.xml,  search for the <server name=”ports-01?> ( as given in your “jboss-service.xml” ) . In this “server name” , search for the “service-config” with <delegate-config portName=”URLPort”/> for the “type=HTTP” and change the port to <binding port=”8180?/> to use 8180 instead of 8080.
