Subject RE: FW: Any known issues with Tomcat 3.2.1 and class loading ?

No, they are not .zip files.  They are .jar files.  Specifically
jndi.jar, ldap.jar and providerutil.jar, which are provided by
Sun for accessing LDAP databases via JNDI.    I was able to
get the Tomcat to load these classes but only by editing the
wrapper.class_path property in the config file.
But I was under the impression that simply putting the Sun jar
files in the WEB-INF/lib directory along with my servlet.jar file
would be sufficient and eliminate the need to edit

Am I off base here?  Is there some limitation to having more than one
jar file in WEB-INF/lib?
