How to run Java application involving DOM3 in a command shell?

Question

Dear all,
I am currently in a testing phase on my Java implementation (in JBuilder 2005) utilizing DOM3(built 2 .jar files from Ant via CVS thanks to dmbdmb). It seems working properly. To experiment its capability of handling big size files, it is essential to do a bit testing by running the application in a command shell (got 'OutOfMemoryError: Java heap size' when run it in JBuilder), something like:
Java -Xmx256m MainHowever it gives out another error of
java.lang.NoSuchMethodError: org.w3c.dom.Node.setUserData(Ljava/lang/String;
Ljava/lang/Object;Lorg/w3c/dom/UserDataHandler;)Ljava/lang/Object;All fine in JBuilder because I configured its 'required libraries' and added up the 2 DOM3 .jar files. Now how should I do to make them working in a command line? I already added the paths of these 2 .jar files to CLASSPATH and also tried to put a copy of them under the same directory as 'Main'. Unfortunately the 'NoSuchMethodError' is not going away...
Thanks to any help

Answer 1

I managed to include these 2 DOM3 jar files into a jar file, xml.jar, together with all other class files. (I put a copy of these 2 DOM3 .jar files and the JDBC connector file, mysql-connector-java-2.0.14-bin.jar into the same folder as with other class files, then run something in the command line like:
D:\>jar cmf manifest.mf xml.jar xmltree/*   //xmltree is the folder/also the package nameThe resulting xml.jar can use the included 2 DOM3 jar files, however another JDBC error occurs when attempting getting a connection to MySQL( details also on http://forum.java.sun.com/thread.jspa?threadID=642812 ). Why do these jar files behave differently, as 2 DOM3 files do well in the xml.jar, whilst the JDBC connector jar does not like it?
Another anomaly is that, though they work well by double clicking xml.jar, the 2 DOM3 jar files still do nothing if executing the jar from a command line as follows:
D:\>java -jar xml.jar      //it still throws out NoSuchMethodError
Why the DOM3 jar files also behave differently depending on how the xml.jar is invoked??
Really cannot work it out & thus need your kind help!
