Subject Re: jar's still not picked up in WEB-INF/lib
Date Wed, 01 Nov 2000 15:28:06 GMT
Aside from the fact that it does not work in certain situations, why would you think it is
not a good idea to put your app specific libs under the WEB-INF\lib directory.  

The spec says to do it.  It allows for good application orginization.  What would be your
arguments against it?

Actually I can think of one argument against it, and that is that by including your libs in
the classpath instead, you can control the order of the classpath.  It appears that using
the libs directory would allow for random ordering (based on OS directory ordering) of these
libs.  Also, I need to include zip files and these don't get picked up anyway.  Maybe using
the classpath is the way to go.

  The Context setup is for the web-app.
  I do not think it is a good idea to put app-depedent
  libs under $TOMCAT/lib. 
  Just for experimentation, I tried placing the JARs under
  $TOMCAT/lib and $TOMCAT/webapps/web-inf/lib.  Does
  not work.
  Tried with 3.1 and 3.2beta6 on WinNT 4.0.

    I would definitely set up a context in server.xml like this:
    <Context path="/Oasis"
     reloadable="true" >
    That should solve you problem.  Otherwise, just put the .jar files in the D:\Java\jakarta-tomcat\lib
directory.  Then the jars would be available for all applications served by tomcat.

      I am experiencing the same problem that others have reported on this topic.  I explicitly
set my Tomcat classpath to be sure of no redundancies in the jars.  I have a Tomcat startup
batch file with one line that adds in all the jars in my WEB-INF\lib to the classpath explicitly.
 When I comment that line out, I get the classnotfound errors.  When I put it back in, my
web app runs fine.  Obviosly I want the line commented out and have the jars picked up in
the lib dir, but that aint happening.

      Because the jars work when explicitly included in the classpath, I conclude that the
jars are not corrupt.  I also conclude, based on commenting out the explicit lib jars classpath,
that there are not redundant jars in the classpath.  I have also checked other sources for
possible classpath jar redundancies and I am just not finding any.

       I am running under Win2000 using jdk1.3.  

      These is the exact dir structure I have set up:


      I have gone through Craig McClanahans list of things to check and all seems to be as
it should.
      Any hope for a fix?  Should I continue to look at my config?  I have heard some people
talk about setting up an explicit context for the app in the server.xml.  Does this solve
the problem consistantly?
