Can't find html page on tomcat server

[Jenny]

Hi,


I am using tomcat 4.1.2.4 on windows 2000 server. I have not problems
to see the tomcat page and /examples folder's pages. I created a
folder /crm under the webapps folder (so it is parallel examples
folder). But I cannot see the html pages in this folder. I have
changed the server.xml and added the Context path tag for the crm
folder and restarted the tomcat.


In crm folder, it has html pages and a WEB-INF folder. The WEB-INF
folder has a web.xml file and a jsp folder and a class folder. The
class folder will be used later when I develop jsp pages in the crm
folder. I have no use of the jsp folder. Can I delete it?


What else do I need to do to make it work?


Here is the server.xml. The only thing I added is the Context path tag

for the crm folder. Thanks a lot!

<!-- A "Service" is a collection of one or more "Connectors" that

<!-- A "Connector" represents an endpoint by which requests are

By default, a non-SSL HTTP/1.1 Connector is established on
port 8080.
You can also enable an SSL HTTP/1.1 Connector on port 8443 by
following the instructions below and uncommenting the second
Connector
entry. SSL support requires the following steps (see the SSL
Config
HOWTO in the Tomcat 4.0 documentation bundle for more detailed

instructions):
* Download and install JSSE 1.0.2 or later, and put the JAR
files
into "$JAVA_HOME/jre/lib/ext".
* Execute:
%JAVA_HOME%\bin\keytool -genkey -alias tomcat -keyalg RSA

with a password value of "changeit" for both the certificate

By default, DNS lookups are enabled when a web application
calls
request.getRemoteHost(). This can have an adverse impact on
performance, so you can disable it by setting the
"enableLookups" attribute to "false". When DNS lookups are
disabled,
request.getRemoteHost() will return the String version of the
IP address of the remote client.

Hi,


I am using tomcat 4.1.2.4 on windows 2000 server. I have not problems
to see the tomcat page and /examples folder's pages. I created a
folder /crm under the webapps folder (so it is parallel examples
folder). But I cannot see the html pages in this folder. I have
changed the server.xml and added the Context path tag for the crm
folder and restarted the tomcat.

first, maybe you should tell also what kind of message exactly you get
from Tomcat. Second, when you put an application in webapps it's
automatically visible. You don't need to put it in the server.xml. And,
if you really want to do it, don't just copy code from another context:
it might misconfigure your application (which is probably the case).

In crm folder, it has html pages and a WEB-INF folder. The WEB-INF
folder has a web.xml file and a jsp folder and a class folder. The
class folder will be used later when I develop jsp pages in the crm
folder. I have no use of the jsp folder. Can I delete it?

If it's there without you wanting it, where did it come from? If you are
working with code you don't know then it might be used somewhere. Better
to leave it where it is.

What else do I need to do to make it work?

maybe it's not related to tomcat, but to the application. Are you sure
it's working?

Under crm folder I put a index.jst which I copied from ROOT folder. I
used URL
http://localhost:8088/crm/.

Here is the error msg:

HTTP Status 404 - /crm/

--------------------------------------------------------------------------------

type Status report

message /crm/

description The requested resource (/crm/) is not available.

If the crm folder does not have a WEB-INF subdirectory with a web.xml
deployment descriptor in it, Tomcat will ignore it as not being a
web application.

[Andrea Desole]

If the crm folder does not have a WEB-INF subdirectory with a web.xml
deployment descriptor in it, Tomcat will ignore it as not being a
web application.

I understand from the OP that it WEB-INF and web.xml are there.

Jenny, do the following:

- remove everything related to crm in the server.xml. If necessary, use
a new installation of tomcat
- don't copy the index.jsp from another application if you don't know
what you are doing. Instead make a simple jsp. Something like

<html>
<body>
hello world
</body>
</html>

- use a very simple web.xml, like

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app>
<display-name>crm</display-name>

<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>

- make sure that your classes and lib directories are empty
