php-java-bridge-users Mailing List for PHP/Java Bridge

sorry, of course that command does not use 256 but only 128 MB.
I use the same values for Xms and Xmx because it should be faster
then continuously allocating more memory.

Ok, i did some testing for you in a 1 GB virtual machine (virtual box -
ubuntu).

The php-java-bridge starts a local servlet container.
But it doesnt stop it. So you should first check that
all java processes have terminated.

ps -ef | grep java

if there still is a java process, kill it.

kill <pid>
(The pid is in the second column of ps -ef)
if this does not help:
kill -9 <pid>

After that try this:

java -Xms128m -Xmx128m -cp JavaBridge.war

If it still complains about php-cgi, then as root:

apt-get install php5-cgi

Before you retry check again if the all java processes have terminated.

I dont know if 256 M will be enough for your production environment.

Regards
David

Hello,

i had a similar problem in a different context. I guess your problem is not
the php-java-bridge.
On a virtual host you often have very limited memory available. How much
memory did you order for your virtual server?

You can use linux commands like
free -m
to find out how your current memory usage is.

Look at your error message. Quite at the start it says:

Caused by: java.io.IOException: Cannot run program
"/usr/lib/jvm/java-6-openjdk/
jre/bin/java": java.io.IOException: error=12,
Cannot allocate memory

So find out how much memory you have available and then adjust the start
scripts of the php test program and of your tomcat.
Look for the java options -Xms and -Xmx
Documentation:
http://download.oracle.com/javase/6/docs/technotes/tools/solaris/java.html

Also dont run too many jvm instances at the same time. I believe the
php-java-bridge test programm starts its own jvm, so dont start the test
while tomcat is runing. I think your virtual machine might not have enough
memory for both instances.

Regards, David
