Hi All,
I was at least able to get the Servlet that was "unavailable"
to finally show up. This has been one of the most frustrating
things I've come across.. :-\
I figured that something was happening in the Servlet before
the Servlet that was being flagged as "unavailable", so I
commented out most of the code in that Servlet, and stripped
it down to a bare minimum. The Servlet that was formally
"unavailable" finally showed up. :-)
So at least I can keep on developing, and later I'll
have to go back and slowly add back piece by piece until it
hits whatever it "didn't like" to flag it as "unavailable".
It would be nice if there was some better information available
as to what it "didn't like" for it to flag it as "unavailable".
Nothing of any value was in any of the log files.
Thanks,
Joe Siebenmann

Subject: Marking servlet ... as unavailable
Hi All,I've hit this problem and my development has come to ascreeching halt.
:-\I'm using Tomcat 5.5.17 with a JDK/JRE of 1.5.0_11on a Windows XP Pro SP2
system.In my Servlets I use:RequestDispatcher dispatcher =
getServletContext().getRequestDispatcher("/servlet/BlahServlet");if (
dispatcher != null ) dispatcher.forward(req, res);to "transfer control" from
one Servlet to the next, and afterseveral of these it finally gets this
Exception when it getsto the doGet() of the next Servlet:Mar 4, 2007 9:19:04 AM
org.apache.catalina.core.ApplicationContext logINFO: Marking servlet
ClientWMIClassesServlet as unavailableMar 4, 2007 9:19:04 AM

at java.lang.Thread.run(Thread.java:595) There aren't any typos, and I've
already deleted every JDK and JREon my system and only reinstalled JDK
1.5.0_11, so that therewould be no possible problems of the "compile JVM" being
differentthan the JVM Tomcat was running, or any CLASSPATH issues, butI keep
getting the Exception. I've also carefully gone oversetclasspath.bat,
catalina.bat and service.bat files making surethe paths to Java and JRE, and
the CLASSPATHs are correct.I also made sure that the final "RequestDispatcher
dispatcher"Object, was valid before I did the forward(). Why is the Servlet
being "Marked as unavailable"???If anyone has ideas on what I can try to fix
thisI'd really appreciate hearing
it.Thanks,Joe Siebenmann _______________________________________________Join
