tag error

[Jacobs, Tim W]

I'm running Tomcat 3.1 with JDK 1.3 on win2000. I get the following error on
one of my applications:
 
Unhandled error! You might want to consider having an error page to report
such errors more gracefully
 
java.lang.NoSuchMethodError
 at
org.apache.jasper.compiler.TagLibraryInfoImpl.createAttribute(TagLibraryInfo
Impl.java:502)
 
Any ideas on what might be wrong?
 
Thanks,
Tim
