FAQ
Hi Guys,

I am trying to build a web interface that can use pig to do "on demand"
batch processing using pig, but JSP (or more specifically, tomcat) does not
seem to want to know pig. I keep receiving ClassNotFoundException when
trying to use PigServer, even though I have explicitly imported it using a
page import statement. I wouldn't normally ask on this mailing list, but all
my other JARs seem to import fine ...

Any help is appreciated,
Robert.

    Are the jars that Pig may use (its libs/), also available in your Web
    app's CP/lib/etc.? Which specific class was reported not found?

    The pig-0.6-core.jar is what is in "WEB-INF/lib" folder, and that is the
    only jar that my non-web projects need. The specific class I was trying to
    use was PigServer which is part of the "org.apache.pig" package within the
    jar, which is imported as "<%@ page import="org.apache.pig.*" %>".
