NoClassDefFoundError Error - URGENT

[vivekm]

Hi,

I am very new to Java. I am trying to use java to parse an XML and XSL file into a plain text file. This procedure is using a new class in a jar file. The files location has been added to the PATH environment variable as well as CLASSPATH (using WINDOWS 2000). No luck.

The command being used is:
java -D com.jclark.sax.xsl.Driver <xml_file> <xsl_file> <output file>

Error returned is:
Exception in thread &quot;main&quot; java.lang.NoClassDefFoundError: com/jclark/sax/xsl/Driver

Thanks,
Vivek

The class name is case sensitive, that's often why I have that error. If that doesn't work, check classpath

How do I check the class names/cases match? Can I delve into the jar files to get this info.

The files, I have been told by previous developer to use are sax.jar, xerces.jar, xp.jar and xt.jar. These files are located in c:\com\jclark\sax\xsl\driver directory along with the XML and XSL files.

Looking at the error,
1. Is it possible that these files need to be located in a special place? If so, where and does my classpath needs to point to this?
2. The error contains '/'. On Win2K, directories are separated by '\' - Is this another problem?

Kind Regards,
Vivek

PANIC OVER!!!! I extracted the contents of the jar file and found the order of directory structure was not com/jclark/sax/xsl/Driver as stated in the documentation but com/jclark/xsl/sax/Driver

THANKS FOR YOUR HELP ANYWAYS.

Regards,
Vivek

Another useful tip to keep in mind is that Jar files are compressed using ZIP algorithm. You can open them using any ZIP utility such as WinZip to explore inside using a GUI utility as well as the jar command-line tool.

Or you can extract at that command line:

jar -xf nameofjarfile.jar
