uploading large streams

[Andries Demont <an...@student.kuleuven.be>]

hi all,

Forgive me to ask all this questions, but I'm a student and my thesis 
needs jackrabbit. I just know you guys know a lot more of it then I 
do, so if anyone would be so kind. You would make me very happy.

I'm trying to upload streams to JCR. When I use to big files I get an 
out of memory error.

Extending the size of memory of java is not an option. Because some 
files can take over 1 Gbyte.

I upload the files with this line:

for instance:

node1.setProperty("White Flag.mp3", new FileInputStream
("helpcontent\\White Flag.mp3"));

Hi Andries,

could you please provide some more information on the jackrabbit 
configuration you are using?

I quickly checked with the default config we use for testing, which is:
- ObjectPersistenceManager + CQFileSystem

uploading a 100 meg file did not increase memory consumption noticably. 
the JVM was fine with a heap size of about 5 megs.

regards

erm, that shouldn't happen, seems to be a bug. i need more information 
regarding your environment:

- jvm heap size
- size of file that causes the OutOfMemoryException
- configuration (repository.xml/workspace.xml)
- are you running jackrabbit stand-alone or within an app server?

cheers
