Using crimson after modifying it

[Alfonso Sánchez-Paus Díaz]

Hello, I have modified the crimson org.apache.crimson.parser.inputEntity.class because it hangs the execution when you attempt to parse a document less than 8K long. Now I am trying to use this new crimson.jar that I build so that I can overcome the problems that I got with the other. I am trying to execute my program using: $ java -Xbootclasspath: "/lib/crimson-1.1.3/build/crimson.jar;/lib/j2sdk1.4/lib/tools.jar;/lib/j2sdk1.4/jre/lib/rt.jar" alfagui_1/ALFA And I get this error message: Error occurred during initialization of VM java/lang/NoClassDefFoundError: java/lang/Object   How do I tell the jre to use the new org tree in crimson.jar instead of the one in rt.jar? Since I only changed the InputEntity class , is there a way to make a shortcut or substitute this class from rt.jar without having to rebuild it?? Thanks a lot, PD I know that this is not a java mailing list but I havent been able to fnd a good answer in the forums at java.sun and I guessed that maybe here you are more used to this kind of thing.
