You comment is not clear...what's the difference between -Xmx &amp;&nbsp;-X?? and which one needs a size argument &amp;&nbsp;which one doesn't?<br />

Hey experts,<br />
<br />
&nbsp;I am running the joost.jar (utility for transforming xml files to other xml files) on a large xml file (10.1 MB) as follows:<br />
<br />
c:\j2sdk1.4.2_08\bin\java -cp c:\work\cmp\deployment\map<wbr />pers\jars\<wbr />joost.jar;<wbr />C:\work\cm<wbr />p\deployme<wbr />nt\ecmp\ta<wbr />ngoe-ecmp-<wbr />app.jar net.sf.joost.Main &quot;C:\Marwan\belgacom\NewStx<wbr />Testing\de<wbr />r_invoice.<wbr />xml&quot; C:\Marwan\belgacom\NewStxT<wbr />esting\bel<wbr />gacomediTC<wbr />DFREE.stx &gt;&nbsp;cdrfree_test.xml<br />
<br />
In this belgacomediTCDFREE.stx file, I am just doing an identical tranformation (the output would be identical to the input - with just difference in newline positions), but it's giving an OutOfMemory Error at the end (while close to completion)...is there any option in which I can give more memory to a jar file that I want to run??<br />

Hey experts,

 I am running the joost.jar (utility for transforming xml files to other xml files) on a large xml file (10.1 MB) as follows:

c:\j2sdk1.4.2_08\bin\java -cp c:\work\cmp\deployment\mappers\jars\joost.jar;C:\work\cmp\deployment\ecmp\tangoe-ecmp-app.jar net.sf.joost.Main "C:\Marwan\belgacom\NewStxTesting\der_invoice.xml" C:\Marwan\belgacom\NewStxTesting\belgacomediTCDFREE.stx > cdrfree_test.xml

In this belgacomediTCDFREE.stx file, I am just doing an identical tranformation (the output would be identical to the input - with just difference in newline positions), but it's giving an OutOfMemory Error at the end (while close to completion)...is there any option in which I can give more memory to a jar file that I want to run??


joost jar - OutOfMemory error

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
