Have you tried putting it in the global web.xml? Not
{context}/WEB-INF/web.xml
I mean the one in
{tomcat install}/conf/web.xml
What that means as far as classloading issues, and whether all webapps
will see the *same instance* of that servlet class, I can't tell you...
but I'm sure that's in the docs.
A more portable solution would be to just include that same servlet in
each webapp, but you know your app/setup better than I...

Not true. All you need to run JSPs is:
1/ a properly configured container (say, Tomcat)
2/ a text editor
Please, that's not a stab at you; I just get frustrated when I see
tutorials throw the kitchen sink at someone.
Ant will make your life easier as you start doing more Java work, and
Apache/mod_jk(2) may help in the long run, but they are certainly not
required to get started with basic JSP/servlet work.

If you're looking for a full restart, there are several ways (in varying
levels of hackishness).
Once you've figured out the trigger (described below), it's a matter of
having that call:
{tomcat script} stop ; {tomcat script} start
Triggers:
1 changes in a file: under Linux, you could use FAM to monitor a file
(say, server.xml). Under OSs that don't support FAM you'd have to do
a periodic poll(), which may cause problems if there are many other
processes poll()ing for files.
2 Tomcat request: under Linux/Unix, a servlet/JSP could fire a
System.exec() that calls an at job. That would put the call
to the script outside of the current process.
(Not sure how calls to System.exec() are prohibited by the default
security manager.)
3 Without the at job, the container could create/update a specified
file watched by the FAM/poll() app...
etc, etc.
If anyone's interested in #1, I'd be happy to drive it. I've been
experimenting with FAM lately, and could probably whip up something that
supports non-FAM OSs, too... If you wanted to stick with Java (make it
cross-platform) that should be fairly straightforward, as well.
If you're looking to reload the *app* on file change, that's probably a
matter of having the trigger kick a JMX action. -but I've reached total
stream-of-consciousness here so I'll stop rambling... ;)

You can do this.
Sort of.
That's what precompilation is all about.
Please bear with me:
- JSPs get compiled down to servlets, either by you (precompiling) or by
the container (at runtime).
- when the container compiles a JSP for you, it takes care of mapping
the servlet to the context-relative URI that matches the JSP. So
/x/y.jsp is mapped, behind the scenes, to some.package.x.y_jsp.class.
To precompile the JSPs means you must tell Tomcat yourself which
classes map to given URIs. Hence the autogenerated file full of
servlet and servlet-mapping entries I described in my last
message.
- When you precompile, you have can even put the classes into a jar file,
but that jar file must be in {dist}/WEB-INF/lib. That's the only way
Tomcat's classloader will find the jar.
- With the JSPs compiled down to code, and properly mapped in web.xml,
you can remove the JSPs from your app.
See
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/printer/jasper-howto.html#Web%20Application%20Compilation
for more details on the precompilation process (assuming TC5). It
mentions the generated web.xml fragment of which I spoke.
: That way the compilation is already done, and nobody can study my .jsp
: files. In theory I could just create a directory tree somewhere of
: org/apache/jsp/ copy all the automatically generated .class files into
: this directory tree and .jar it all up, and Tomcat should find them either
: in /WEB-INF/lib or in /work/Standalone/localhost/$applicationDir, but it
: doesn't.
Close, except that the jar of JSPs must exist in {dist}/WEB-INF/lib.
Tomcat won't load a jar from the context dir itself, aka
.//localhost/$applicationDir. Just not how Tomcat works. ;)

The phrase completely functioning on another server is the tipoff --
what's in the working server's {tomcat inst}/common/lib? Anything
JavaMail related?

Re: Does the isThreadSafe page directive work in Tomcat 5.0.18?

Those specs deprecate SingleThreadModel and isThreadSafe, respectively. -QM -- software -- http://www.brandxdev.net tech news -- http://www.RoarNetworX.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Does the isThreadSafe page directive work in Tomcat 5.0.18?
: Would it be a good idea for Tomcat to print out a warning about this : deprecation? Not my say -- I'm neither on Sun's board for specs, nor a Tomcat developer. ;) Seriously, though: this is an issue that could argued either way, so my guess is that the Tomcat crew decided in favor of the one way and that's how it turned out. -QM -- software -- http://www.brandxdev.net tech news -- http://www.RoarNetworX.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Yes and no. ;) 1/ Yes: check the servlet spec for method signatures. For example, a servlet's doGet() throws (IIRC) just a ServletException; so any Servlet subclasses must wrap exceptions up in a ServletException. 2/ No: #1 excludes subclasses of RuntimeException (e.g. NullPointerException) and Error, which can be thrown at any time yet needn't be declared in a method signature. -QM -- software -- http://www.brandxdev.net tech news -- http://www.RoarNetworX.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Servlet won't run init()
: Hello, : I want a servlet to run its init() method when I start Tomcat. I put : the following entry in web.xml but that doesn't do it: : [snip] Please, humour me: put load-on-startup after init-param. I believe that's the order per the servlet spec. Humour me, part 2: verify the method signature of your servlet's init(). A small typo makes the difference between overload and override... Other than that, some details would be nice: Tomcat version, log messages, what have you... On an unrelated note: is there any reason you're using load-on-startup instead of lifecycle listeners? -QM -- software -- http://www.brandxdev.net tech news -- http://www.RoarNetworX.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: jsp deployment
: Tomcat chokes when the jsp is requested. I get a 404 : error, the requested resoruce is not available. : : What do I need to configure to get Tomcat to serve the jsp? Chances are it's a permissions issue on the file. (Unless you've tweaked Tomcat's config, it should already be able to serve JSPs.) -QM -- software -- http://www.brandxdev.net (C++ / Java / SSL) tech news -- http://www.RoarNetworX.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
