JCR-RMI beginnings....

euleon — Tue, 18 Nov 2008 09:15:29 GMT

Hello:I've trying to understand the RMI API that is in extension-jcr-rmi-1.0.0-src.zip in order to use it to develop a layer for my Company.I've installed it successfully. I've also added and configured properly this module (in order to solve the issue commented in the forum):extension-jcr-thread-bo

The address 127.0.1.1 is diagnostic and you will find postings on this forum and the web discussing this Linux/RMI "feature".

Try the following to your java command line or eclipse environment where x.x.x.x is your IP address.
-Djava.rmi.server.hostname=x.x.x.x

Other similar threads have pointed out that on Linux the localhost entry in /etc/hosts may need to be changed to the ip address of your machine.
And also check that you don't have a firewall blocking access to the necessary ports.

If you continue to have problems then please also specify which version of Alfresco you are using.

Hello, and thank you!

I've tried to change in /etc/hosts the alias localhost=127.0.0.1 with x.x.x.x (my server IP)

It was a disaster!It doesn't bind
So, now I'll try to add the option -Djava.rmi.server.hostname=x.x.x.x to the JVM of the server. Is that right? I mean: Do I have to add that line in the client's JVM or in the server's JVM?

If is in the server side where I have to add it, as the JVM is called from TOMCAT where must I place this property?
Thank You

Finally I've found the solution:

What I had to do is to tell TOMCAT how to start the JVM telling that the IP associated to RMIREGISTRY were the server's IP. In my case, the ip is: 192.168.1.102

So, the option I had to add was: -Djava.rmi.server.hostname=192.168.1.102.
Where did I add this line? in the file catalina.sh that is located in $TOMCAT_INTALL_DIR/bin. There is a variable called JAVA_OPTS. The first time you find it in the file, is the right place to add this flag. This is the correct way:
JAVA_OPTS="$JAVA_OPTS "-Djava.rmi.server.hostname=192.168.1.102""
It's really important NOT TO FORGET THE LAST ". If you forget it, the variable won't be initialized with that option.

As help I post you my catalina.sh file. Every few lines you'll find comments like *********************string**************************
or ++++++++++++++++++++string+++++++++++++++++++++. Those are all the places in the file where catalina uses the JAVA_OPTS variable.
You'll see also that there is a BUG DUMP file called luis (that is created in the root directory as "/luis")that will help you to know which part of the script is executed.

Don't forget to reboot TOMCAT!

I hope you help this!

BR.

# Start/Stop Script for the CATALINA Server
#
# Environment Variable Prequisites
#
#   CATALINA_HOME   May point at your Catalina "build" directory.
#
#   CATALINA_BASE   (Optional) Base directory for resolving dynamic portions
#                   of a Catalina installation. If not present, resolves to
#                   the same directory that CATALINA_HOME points to.
#
#   CATALINA_OPTS   (Optional) Java runtime options used when the "start",
#                   or "run" command is executed.
#
#   CATALINA_TMPDIR (Optional) Directory path location of temporary directory
#                   the JVM should use (java.io.tmpdir). Defaults to
#                   $CATALINA_BASE/temp.
#
#   JAVA_HOME       Must point at your Java Development Kit installation.
#                   Required to run the with the "debug" or "javac" argument.
#
#   JRE_HOME        Must point at your Java Development Kit installation.
#                   Defaults to JAVA_HOME if empty.
#
# JAVA_OPTS       (Optional) Java runtime options used when the "start",
#                   "stop", or "run" command is executed.
#
#   JPDA_TRANSPORT (Optional) JPDA transport used when the "jpda start"
#                   command is executed. The default is "dt_socket".
#
#   JPDA_ADDRESS    (Optional) Java runtime options used when the "jpda start"
#                   command is executed. The default is 8000.
#
#   JPDA_SUSPEND    (Optional) Java runtime options used when the "jpda start"
#                   command is executed. Specifies whether JVM should suspend
#                   execution immediately after startup. Default is "n".
#
#   JPDA_OPTS       (Optional) Java runtime options used when the "jpda start"
#                   command is executed. If used, JPDA_TRANSPORT, JPDA_ADDRESS,
#                   and JPDA_SUSPEND are ignored. Thus, all required jpda
#                   options MUST be specified. The default is:
#
#                   -Xdebug -Xrunjdwp:transport=$JPDA_TRANSPORT,
#                       address=$JPDA_ADDRESS,server=y,suspend=$JPDA_SUSPEND
#
#   JSSE_HOME       (Optional) May point at your Java Secure Sockets Extension
#                   (JSSE) installation, whose JAR files will be added to the
#                   system class path used to start Tomcat.
#
#   CATALINA_PID    (Optional) Path of the file which should contains the pid
#                   of catalina startup java process, when start (fork) is used
