What output did you expect? We have no clue as to
what /root/Desktop/project/SAXXMLHandler is supposed to produce.
How do you determine that there is no output?

I have installed Java on my PC and am trying to convert an XML file
using a conversion XSL statement.
I first run the following 2 lines of code:
Upon completion of that, I navigate to the path that contains the XML
file that I wish to convert as well as the XSL file that will do the
conversion. I run the following command:
java org.apache.xalan.xslt.Process -IN INTERNAL_CANDIDATE.xml -XSL
conv_profiles.xsl -OUT INTERNAL_CANDIDATES_UAT_LOAD.xml=
After running this command I get the following error:
Exception in thread "main" java.lang.NoClassDefFoundError: java
Can anyone explain to me what is going on?

Hello all, how is everyone doing; good I hope. Anyways, I was wondering how
I can edit the jvm settings. I have the following error:
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
I read that this is caused by not having the jvm set high enough in memory;
or an infinite loop.
If I try to edit the jvm settings; do I do this in eclipse or add some
commands to my actually code?
Any thoughs, always apprecited thanks again.

If you're using Eclipse, try adding the following: choose the menu option
"run", the "run" again, and you get an option screen. There, you choose
"new" to define a new configuration for your current project.
As soon as you have done that (or select an existing project), there are
several tabs on the right. One of them reads "(x)= Arguments". Select that

I have a question related to GUI programming.
I created a GUI using GUIDE and it includes a popupmenu and a axes
and some other push buttons. I put a surface() function in the GUI
opening function in order to create a figure in the axes. The figure
can be displayed correctly in the axes, however, the popupmenu is
invisible(the other push bottones shows correctly). It is so weired
for me. BTW, I created this GUI by using Matlab 7.0 release 14.0.
Does anybody know what is wrong with my GUI?
Thanks in advance!

Maybe u selected the 'visible off' option in the property inspector
for the popupmenu. Try double-clicking on the popupmenu in the GUIDE,
it will open up a new window. Look at the property labeled 'Visible'.
It should be made 'on'.
Thanks for the reply, Pratik.

...java threads kernel 2.6
I have kernel 2.6.5, JDK 1.4.2.
I have a multi-threading java server application.
Unlike my old version of Linux (kernel 2.4.25), I don't see the number of
threads my application is running with the "top" linux command. I only see
one "java" process.
I understand this is due to the new NPTL thread architecture under Kernel
Is there an other way than the "top" command to display the number of
threads of my application is using and without Java debuging ?
Thanks in advance
