          No...

          Can i send email for you with more details? I will printscreen the terminal and this can be better for you analyse what's wrong.

          Can you pass your email address?

            How are you starting the app server? Are you trying to run it on os startup using a script in /etc/init.d? Or are your running it manually from a terminal.

            If you are running it manually from a terminal, at the terminal, enter this:

            echo $JAVA_HOME

            If you do this, you should see:

            /usr/java/jdk1.5.0_16

            If you do not, then JAVA_HOME is not set properly.

            Based on the starting part of the console log you posted:

              Peter

              During all these tests, i was login with my user (no root but with the same permission) and for a test i try to run the JBoss like a root user.

              I didn't found any problem.

              Certainly the problem is with permissions of my user.

              The first problem is solve.


              Now, i have other question:

              How can i set the heap size? Minimum and Maximum memory for the Virtual Machine...

              Oh my...

              Thanks.

                Edit the setting that are already present in run.conf:

                JAVA_OPTS="-Xms128m -Xmx512m ..."

                  Hey Peter

                  I tried to edit the run.conf file for setting the memory for Virtual Machine and edit the option that you told me. But when i started JBoss this message appear:

                  =========================================================================

                  JBoss Bootstrap Environment

                  JBOSS_HOME: /usr/jboss/jboss-4.2.2.GA

                  JAVA_OPTS: -Dprogram.name=run.sh -server -Xms128m -Xmx2048m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -Djava.net.preferIPv4Stack=true

                  CLASSPATH: /usr/jboss/jboss-4.2.2.GA/bin/run.jar:/usr/java/jdk1.5.0_16/lib/tools.jar

                  =========================================================================

                  is it correct? I don't think so...

                  Could you help-me?

                    Are you running a 32-bit or 64-bit JVM? If 32-bit, the max heap size might be too big (depends on the OS). Some OSes will allow only 1.5-1.7GB heaps.

                    Also, are you sure you need that much heap space? I have a presentation on how to understand what heap settings work best at: http://www.cecmg.de/doc/tagung_2007/agenda07/24-mai/2b3-peter-johnson/index.html

                      I just wanna test if JDK (x64) and JBoss works well in a x64 system. Because this i would like to set a big memory...

                      But this message "JAVA_OPTS: -Dprogram.name=run.sh -server -Xms128m -Xmx2048m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -Djava.net.preferIPv4Stack=true" appeared before edit the file.


                      I'm running a 64 bit JVM.

                        I guess I do not understand what you are asking.

                        Is there a problem when you run with those settings?

                        Or are you asking me to approve those settings? If so, see the presentation I provided a link to.

                        Also, you must have already edited the run.conf file - the original Xmx size is 512m

                        In general, never set Xmx larger than your RAM size. And never set it larger than what you really need (see my presentation to answer that).

                          Hi,

                          I am facing exactly the same issue. When I move to a 32 bit JVM it works. But due to some special requirements I cannot use the 32 bit JVM in my production environment.

                          I am using the JBossService.exe to create the windows service. Is there a different JBossService.exe for x64 bit systems.

                          Thanks in advance

                            Don't use JavaService if is only supports 32-bit. Use JBoss Native instead - it has a 64-bit version and I have used it on my system (64-bit Vista).
