[antlr-interest] ANTLRWorks debug woes...

[Alexander James Rickett]

Hello,

I'm trying to use the debug in ANTLRWorks with a sample grammar from a tutorial. The grammar checks out, and generates code fine, but when I go into the debug menu, and choose "debug" I get the error message "Compliler failed with result code 1" and get the following message in the console:

[11:29:03] D:\workspace\AntlrCobol\src\grammarEtc\tempParser.java:10: cannot access org.antlr.runtime.debug.DebugParser
[11:29:03] bad class file: C:\Documents and Settings\Alexander_401007\My Documents\antlrworks-1.2.2.jar(org/antlr/runtime/debug/DebugParser.class)
[11:29:03] class file has wrong version 48.0, should be 47.0
[11:29:03] Please remove or make sure it appears in the correct subdirectory of the classpath.
[11:29:03] public class tempParser extends DebugParser {
[11:29:03]                                 ^
[11:29:03] 1 error

I'm using this at work, and we have pretty strict firewall policies so I'm not sure that remote debug is an option....  ALSO, subsequent calls to debug, yield a greater variety of wrong-version files:

I'm running ANTLRWorks 1.2.2, on XP professional, I haven't done any class path
configurations, though I've used a few ANTLR plugins in eclipse...  Please tell me if any other information would be helpful...  The grammar I'm trying is below,  Thanks so much.
