Subject cvs commit: jakarta-tomcat-connectors/jk/native2/include jk_env.h
Date Wed, 06 Feb 2002 19:18:21 GMT

  Modified:    jk/native2/include jk_env.h
  Log:
  Initial work on the exception mechanism, that would allow more meaningfull
  error messages out of jk. We can live without it, so it's low priority.
