Problem in setting up tomcat
Posted by Ketan Patel <ke...@yahoo.com>.
Hi all,
I have windows'98 machine. I am trying to install tomcat in this
machine.
I had set JAVA_HOME and TOMCAT_HOME.
when i start startup.bat then after adding context of all the projects
like test, examples, admin etc... it gives me following error and it
shut out.
This error i can not trace out that for what reason this comes.
FATAL:java.net.SocketException: Option unsupported by protocol: create

Re: newbe: class directory question
Posted by Charles Webber <ch...@earthlink.net>.
Oh, and one other piece of information. If I change the URL manually, so
that I say http://localhost/book/servlet/coreservlets.ShowParameters, the
servlet appears to display stuff properly, even though it doesn't have
values from the html form passed through.
What I am hoping to get is the answer on where I should place my servlets,
and how to configure Tomcat so that I can simply use
http://localhost/book/coreservlets.ShowParameters and get the same output.
Hope this helps.

Re: newbe: class directory question
Posted by Charles Webber <ch...@earthlink.net>.
OK - let me try to make this as clear as possible.
Other than the information I provided below, here is what happens.
HTML page says: <FORM ACTION="coreservlets.ShowParameters". This HTML form
is in $TOMCAT_HOME/webapps/book.
So, when the URL says http://localhost/book/form.html, I get the form with
no problem, as Apache knows where this is located. However, when I click on
the 'Submit' button, I get the 404. Right now the servlet is located in
$TOMCAT_HOME/webapps/book/coreservlets/. Isn't that the right place?
Thanks.

Since you *still* didn't say what URL you were trying to submit to :-), I
will make an assumption.
The correct URL for the "book" servlet would be:
http://localhost:8080/book/book
because you're using "/book" both as the context path *and* as the servlet
path. URL patterns in <servlet-mapping> entries are relative to the
context path of the web application, not from the base of th server.
See the servlet spec for more information.

Re: newbe: class directory question
Posted by Charles Webber <ch...@earthlink.net>.
Thanks Craig - here is some more detailed info:
web.xml file does contain a <servlet-mapping> section. The name of the
servlet is ShowParameters, which is part of a package called coreservlets.
The web.xml file contains the following:
<?xml version="1.0" encoding="ISO-8859-1"?> <!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
"http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
<web-app>
<servlet>
<servlet-name>ShowParameters</servlet-name>
<servlet-class>coreservlets.ShowParameters</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>ShowParameters</servlet-name>
<url-pattern>/book</url-pattern>
</web-app>
The server.xml file contains the following in the context section:
<Context path="/book"
docBase="webapps/book"
crossContext="false"
debug="0"
reloadable="true" >
</Context>
My HTML file contains a form, and the action is
"/book/coreservlets.ShowParameters".
However, the submit button doesn't point Tomcat to the correct place, as the
servlet isn't found.
Any suggestions? Any other questions?
Thanks

You don't actually have to do this, if the directory is under "webapps" --
Tomcat will recognize it automatically.

Have you got a <servlet-mapping> in your /WEB-INF/web.xml file?
The only way to solve problems like this is details - please post the
directory structure and its contents, the contents of the web.xml file,
and the URL you are trying. Otherwise, there's no hope of helping you
figure out where you haven't got things quite right.

Re: newbe: class directory question
Posted by Charles Webber <ch...@earthlink.net>.
Ok - I have basically the same question when it comes to Servlets. I've
created the proper directory structure for a new web application under
$TOMCAT_HOME/webapps, placed a new context in server.xml, and created a
web.xml file pointing to the servlet class, but still I can't find it
without using /servlet/ as part of my URL. How come?

Just a caution, related to your second question.
All servlet containers supporting the Servlet 2.2 or 2.3 specs do indeed
support unpacked classes in WEB-INF/classes, or JAR'd classes in
WEB-INF/lib. This is defined in the servlet specification, which can be
downloaded from:
http://java.sun.com/products/servlet/download.html
and makes useful reading in order to understand what is portable and what
is not.
Most containers provide mechanisms to make classes available to all web
applications, but this is *not* standardized, or even guaranteed to be
available.
