Re: Servlet directory?
It's under this directory, /WEB-INF/lib or /WEB-INF/classes of any webapp that you have. Then define the servlet for the web app in web.xml . There are quite a few good examples on this that ship with many jakarta projects. So download a few and take a peek at it. Jørgen Ramskov wrote: Hi I'm trying to some software called ArcIMS.

Re: Servlet directory?
Me again, Forgot to mention that in TC4.1.12 and above, the invoker servlet is off by default. You will have to map it to a different url in the web.xml. Something other than servlet. Then change the diagnostics urls to match. From Tim Moore, You have two choices for how to fix this problem. 1. You could go into tomcat/conf/web.xml and re-enable the servlet-mapping for the invoker (it's just commented out). This is the fast way. 2. You could create a URL mapping in your webapp's web.xml file for and then use that URL to access it. This is the better way. The invoker servlet can be dangerous, and it's now recommended that you leave it disabled. You'll need to map your servlet to a URL. So that being said, I think you should do something like, For example, add this to your web.xml in the TOMCAT_HOME/webapps/arcimsServletConnector/WEB-INF/ servlet-mapping servlet-namecom.esri.esrimap.Esrimap/servlet-name url-pattern/com.esri.esrimap.Esrimap/url-pattern /servlet-mapping And then go to http://your_server/arcimsServletConnector/com.esri.esrimap.Esrimap?CMD=connectorping http://your_server/arcimsServletConnector/com.esri.esrimap.Esrimap?CMD=appserverping I haven't tested the correct way, I just uncommented the system web.xml file. I only do local host stuff on my desktop for developing.

Re: Servlet directory
The way you are trying to access this servlet implies a couple of assumptions: 1. Your servlet is in the default package. That is to say that it exist in WEB-INF/classes and not some directory deeper inside of that. 2. Your class is all lower case myservlet since that is how it is written on the URL your provided below. I think it is probably likely that #1 is true. However, I'm guessing that #2 is not. The general practice for naming classes is to use Capital letters for each distinct part of the class name. For instance, you probably named your class MyServlet, not myservlet. As such, the URL you provided won't work. It should be: http://localhost:8080/myapp/servlet/MyServlet Note that servlet and servlet-mapping entries in your own web.xml have nothing in particular to do with accessing your class through Tomcat's default servlet invoker which is mapped to /[your context]/servlet/*. The other thing you should look at is that the directory that your app is running out of exists in: $TOMCAT_HOME/webapps/myapp make sure that myapp is in all lower case. Oh, and make sure that there are no spaces in $TOMCAT_HOME. If you have it installed in a directory like Program Files, you can do the following (on Windows). I'll use my setup as an example. $CATALINA_HOME=C:\Progra~1\Apache~1\Jakarta\tomcat-4.1.8 The original path is: C:\Program Files\Apache Group\Jakarta\tomcat-4.1.8 Just use the tilde's to fix directory names which have spaces. The names with tilde's can be no more than 8 chars long. Restart Tomcat after using the hints above and things should work just fine.

Re: Servlet Directory
Adding a context path in server.xml is just one part to it (BTW, in docBase you might want to use a fully qualified path rather than a relative path).

RE: Servlet Directory
Hi,
Just to spell things out a bit clearer:
The code for a servlet class, and any non-library
classes it uses, must be in the classpath. Your
best options are:
(a) put them under {yourwebapp}/WEB-INF/classes,
in a subdirectory that matches your package structure.
(b) put them in a jar file, in {yourwebapp}/WEB-INF/lib
In either case above, tomcat automatically adds the
directories/libs to its classpath when it starts.
You *can* put your servlet classes elsewhere on your
disk, and make sure your CLASSPATH points to them
before starting tomcat, but there are many disadvantages
to this, including making it difficult to install your code
elsewhere, and not being able to use the servlet
auto-reload feature.
Now that your class is *loadable* by tomcat, you need
to tell tomcat what URLs map to what servlets.
There is an entry in $TOMCAT_HOME/conf/web.xml which
sets up a default mapping for servlets; for any url of form
/webapp/servlet/servletname, an attempt is made to
do a "loadClassForName(servletname)" and if
successful, the request is passed off to the found class.
Of course, the class to be loaded merely has to be in
the classpath somewhere (see (a) and (b) above).
[[NB: this only applies in tomcat3.1; I hear that tomcat3.2
does not have a $TOMCAT_HOME/conf/web.xml file,
in which case I'm not sure how or if the default servlet
mapping gets set up...]]
If you don't like this default mapping, you just define
your own (url-servletclass) mappings in the file
yourwepapp/WEB-INF/web.xml. See the file
$TOMCAT_HOME/conf/web.dtd to see what tags
are allowed in the web.xml file; then read the sun
servlet specs. NB: don't modify the web.xml file
in TOMCAT_HOME/conf, create your own inside
your webapp/WEB-INF.
Note that the servlet class *never* lives *at* the
url that the user enters; the url is always looked up
to find a corresponding class name, and then the
servlet class is loaded from the classpath.
I hope this clarifies things a bit...
Regards,
Simon

Hello all,
First, let me apologize... this is so simple... but i have been beating
my head against the wall for almost 20 hours straight now...
I have successfully installed Tomcat on my Solaris... With Apache 1.3.14
Everything seems to be working fine... JSPs work well... looking through
the logs... no errors... but i can not get any servlets to work in my
defined servlet directory. I must be missing something very simple.
When i try to invoke a servlet, the tomcat.log file shows:
Context log: path="" Class Not Found in init
java.lang.ClassNotFoundException: testAllego
In my tomcat.conf file.. i have the line:
ApJServMount /servlet /root
And i have this in my server.xml file:
Context path="" docBase="/export/home/cni/servlet" debug="0"
reloadable="true"
/Context
I feel like i am so close... because ay least it is "trying" to load the
servlet class... but tomcat can't find it..
please help... i need some sleep...
thanks in advance.
