SV: SV: [jdom-interest] Memory problem

[Marcus Andersson]

No. I'm using the XML documents as a simple database. The RMI object only
act as a remote facade to access the XML. The data that is sent through RMI
is "normal" data objects instantiated from XML data instead of a jdbc result
set (I like Xpath better then SQL).

The memory problem I had is solved since I checked out the latest code from
CVS (think it was something with StringBuffers according to a mail by
Jason).

I have perhaps not used the most scientific way. I comment out the

Then I uncomment the lines that builds the document and then checks 
the size again. I then take the second value and subtract with the 
first value. Very simple. The "program" is a RMI object and the only 
thing that happens before the document parsing is that I bind the RMI 
object to the registry. The program takes about 40Mb without the 
document and about 150Mb with the document (which tells me that I 
have to revise what I said earlier, the document is "only" about 
110Mb big in memory).


You say you're using RMI. Are you actually serializing the Document 
using object serialization?
