java.lang.OutOfMemoryError: Java heap space
I have tried to send 10Mb file to jackrabbit repository and this exception
has been thrown
org.apache.jackrabbit.rmi.client.RemoteRepositoryException: Error occurred
in server thread; nested exception is:
java.lang.OutOfMemoryError: Java heap space: Error occurred in server
thread; nested exception is:
java.lang.OutOfMemoryError: Java heap space
........
If I tried it with smaller file(about 5 Mb) it was working good.
I have tried to set JVM memory greater (512Mb) by command "java -Xmx512Mb"
but nothing changed.
Does someone have experiences with it?
Thanks for help
Michal Hybler

Thanks it has been number 2 :) a had to set up it on tomcat in some manager
that it provides.
I have one more question...can i set bigger memory only for jackrabbit
apliccation or is it possible only for whole tomcat?

I was referring to the usage message you posted earlier:
c:\>java -Xmx512m -Xms512m
Usage: java [-options] class [args...]
(to execute a class)
or java [-options] -jar jarfile [args...]
(to execute a jar file)
The usage message is caused by the fact that you didn't provide the
"class" or "-jar jarfile" part of the command line. The -X options are
just fine.

OK.
None of this sounds too troublesome, so there's three main candidates
for the cause of your problem: 1) a memory leak in JCR-RMI, 2) your
memory settings (-Xmx512m) aren't active, 3) there's some other
application that's hogging all available memory.
I'm not sure how to best trace this, I tried this with a simple test
case but couldn't duplicate your problem. Can you post the full stack
trace you are receiving and the relevant parts of your client code
where you upload the file and save the transient state?

OK, no problem there.
The OOE seems to come from the server. Are you setting the -Xmx512m
option on the server or the client JVM? The java usage message you
displayed in the recent message is just caused by the fact that you
didn't provide a class or jar file to run.
How are you running the RMI server? Is it the Jackrabbit webapp, the
JCA adapter, or a standalone process where a custom class starts up
the repository? Do you have some other applications running in the
server JVM?

How do you upload the file? Are you creating a normal binary property
or doing an XML import? Do you call save() after uploading the file or
only after multiple changes?

I use simplePresistenceManager and Postgre database
I try to use "-Xmx512m" but problem is same I think there isnt problem.
Do you have any ideas where is the probem?

AW: java.lang.OutOfMemoryError: Java heap space
Posted by Robert Gacki <ro...@softgames.de>.
He has a typo in his java arguments:
"java -Xmx512Mb" -> the "Mb" is wrong.
Michal, try "java -Xmx512m -Xms512m" instead.

I have managed to put more than 100mb file to Jackrabbit (remotely) -
with default memory configuration. I have use Derby Db, and Derby
persistence manager. It took some time but worked (however, other
work was impossible due to single connection to th database).
Can you specify your configuration, and put slightly more line of
stacktrace?

maybe because the syntax is wrong: it's just -Xmx512m (not Mb).
