myapp question

[Jacob Kjome <Ja...@syntegra.com>]

I have been having a problem setting up the myapp webapp that comes in the
sample folder in the docs.


Now, I did end up being able to run it, but not until I changed the class
from Hello.class to some other name, such as HelloWorld.class

as soon as I did this, it ran just fine.

I had been thinking it was the web.xml file, but no matter what I did, it
would give me this error when I ran the Hello.class

Error: 404
Location: /myapp/hello
File Not Found
/myapp/hello



Does Tomcat just not like the name Hello.class for a classname??? Unlikely!
My theory is that I had things improperly set up at first and ran the
Hello.class servlet and it got a 404 error and cached that output for the
Hello.class.  Is there a place in Tomcat where it caches the output of a
class?  Is there a way to flush it?


I have had no problem getting a servlet by any other name running
correctly????


Thanks,

Jake

Carl,

I did not see any answer to your question. I apologize if someone already
replied.
The compiled JSP code is stored under the $TOMCAT_HOME/work directory. You
will find one sub directory per context you have set up. You can flush it by
deleting the files within those sub directories. It will force tomcat to
recompile.
If you just want to reload a class that you modified, you can set the
context's reloadable parameter in server.xml to true, or just restart tomcat.

JSP & cache

Does Tomcat cache JSP code? And if so how do you flush it?

There's no restrictions on filenames that would mess this up.  The correct URL
is supposed to be "http://localhost:8080/myapp/hello" because that is what the
<servlet-mapping> entry says.  And, the class name it looks for is Hello.class
(because that is what the <servlet> entry says).

The only reason you would get a 404 is if the web app was not completely
deployed.  After you build it, you should end up with the following files
(assuming you are deploying into the "webapps" directory under $TOMCAT_HOME):

    $TOMCAT_HOME/webapps/myapp/
        WEB-INF/
            web.xml
            classes/
                Hello.class
        hello.jsp
        index.html
        images/
            tomcat.gif

If there was a compile error, or if you didn't do the "build compile" step, the
class file might not be there.

Be sure you restart Tomcat after making any changes, unless you've set up this
context for auto-reloading in the "conf/server.xml" file.
