example prevents Tomcat start throwing java.lang.IllegalAccessError
I've tried to use the struts example from the latest nightly build
(jakarta-struts-20000619.tar.gz).
I copied struts-example.war and struts-documentation.war to webapps
directory under TOMCAT-HOME.
I started Tomcat, the .war files get expanded, but Tomcat exits with the
chain of exceptions listed below.
Rolling back the changes it seems that having struts-example in webapps
caused the failure. Other applications including struts-documentation runs
OK when struts-example is removed from webapps. It seems that the error
causing Tomcat to exit occurs when actually trying to execute struts-example
(index.jsp in fact). This happens at startup due to the load on startup tag
in web.xml for struts-example. When load on startup is reset to 0, when
trying to execute index.jsp under struts-example, Tomcat doesn't exit but
throws the exception below
The error seems to be caused by a call to an inexistent method or something
like that so my feeling is I have an outdated jar, one which is related to
XML processing but I'm not sure which one.
I have also a concern about the fragility of Tomcat 3.1 which fails to start
when having a "misbehaving" application. This shouldn't happen or am I
missing something?
Until I get deep down in the code to find where the error comes from, can
anybody give a clue?
My configuration: Tomcat 3.1 standalone on a Windows 2000, JDK 1.2, Tomcat
runs Ok except the struts-example.
Thank you,
Marius

Hi All,
I have been lurking and want to add my two cents.
VisualAge is a fantastic development environment! I have been using it for
almost 2 years, and find the debugger 1st rate.
I would highly recommend it!!

Absolutely, Tomcat with IBM's VisualAge for Java. Incremental compile; in
a split second you can hit the browser page to check the
result. Interactive debugger; logs are in VAJ too. Love it.
There's documentation on how to set up the free version. Or, pay the $120
for the Pro version; there's an easier setup. It's a bargain.

VisualAge for Java Entry Edition.
IBM www-site has a hands-on tutorial on using tomcat with visual age for
debugging servlets. I haven't tried myself although...

Craig, thank you very much for your support!
It works now. :-)
First, the JDK I used was one taken from Oracle JDeveloper 3.0 for Windows
NT (running on a Win2K)
java version "1.2.2-JDeveloper"
Ferrari VM (Copyright (c) 1998, 1999 Oracle Corp. Version 1.2.184 odv,
nojit)
I had no problems with tomcat and this JDK until I tried to set up struts.
Then I run into the error which makes the subject of this thread.
I have installed Sun JDK 1.2.2 :
java version "1.2.2"
Classic VM (build JDK-1.2.2-W, native threads, symcjit)
and struts example run OK.
Other remarks:
- I have replaced xml.jar with jaxp.jar and parser.jar in %TOMCAT_HOME%\lib
- As you might guess the error was thrown when compiling the jsp files. Once
the files were compiled the example run even with the first JDK I used.
(well, so it seems :-) )

Yes, they "conflict" in the sense that they both have some classes with the same
names. The JAXP parser happens to have the same name and behavior as the one in
xml.jar so it works with Tomcat 3.1.
Could you please do a "java -version" at the command line and report back what
it says? (There might have been problems with early versions of 1.2.2 as well
-- I have to consult some notes to be sure).

Aren't jaxp.jar and parser.jar conflicting with xml.jar? I mean should I put
jaxp.jar and parser.jar in lib under TOMCAT_CONF near xml.jar?

Deep down, the IllegalAccessError problem with Tomcat 3.1 is actually caused by a
compiler bug, if you try to compile it (Tomcat) with a JDK 1.1 or 1.3 compiler.
Be sure you are using the final binary release distribution.
I have had no problems at all running the Struts examples under Tomcat 3.1, as
well as the most cutting edge versions of Tomcat 3.2dev, in the following
environments:
Linux (Red Hat 6.1), Sun JDK 1.2.2
Windows98, Sun JDK 1.2.2
I have had IllegalAccessERror problems with Tomcat 3.1, especially when you try
to incorporate another XML parser (as Struts does, because it requires the
jaxp.jar and parser.jar files), trying to run under JDK1.1 or 1.3. These
problems have not surfaced when running a recent nightly release of Tomcat 3.2,
however, because Tomcat 3.2 also uses JAXP for XML parsing (instead of
"xml.jar").
