[jdom-interest] about memory limitation when using jdom

[Benjamin Kopic]

Hi Shinnie

I had a similar problem, and I believe there are 2 ways of doing it:

1) Using ElementFilter and your own JDOMFactory implementation, which
would create only the elements you need.

2) Using dom4j API instead, which seems to be more geared to large
(preferably with a shallow tree) XML documents. Have a look at:

http://www.dom4j.org/faq.html#How%20does%20dom4j%20handle%20very%20large%20XML%20documents?


Best regards

Ben

    Hi all,
    I use jdom to export all data  from database about 10,000 records.
    
    I use SAXBuilder to build an xml and export a xml in ONIX (Online
    information exchange) format.
    
    My pc's memory is 256m and I use -Xmx512 java vm parameter to run it. But it
    still
    runs out of memory.
    
    I don't know what's the mechanism for jdom to build, can jdom build a xml
    just like 
    SAX (using the least memory). Or there are other methods.
    
    Any help is appreciated!!
    
    Thanks
