You've deployed this in the ROOT webapp?
form action should be "/firstpack/JustALittleTest"

OK so now I have this:
action="JustALittleTest/firstpack/JustALittleTest"
For a web.xml of file of:
<servlet>
<servlet-name>JustALittleTest</servlet-name>
<servlet-class>firstpack.JustALittleTest</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>JustALittleTest</servlet-name>
<url-pattern>/firstpack/JustALittleTest</url-pattern>
</servlet-mapping>
And I get requested resource not found.

check your ./WEB-INF/web.xml

<servlet-name>FooServlet</servlet-name>
<servlet-class>FooServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>FooServlet</servlet-name>

</servlet-mapping>
reference to invoke is
ServletServletNameFromWeb.xml/Url-patternFromActionMapping
e.g.

If the url-pattern should be /firstpack/JustALittleTest then should the
form on the JSP refer to action="firstpack.JustALittleTest" or
action="firstpack/JustALittleTest" ?

When I use this entry I get a request resource not found error.
<servlet>
<servlet-name>JustALittleTest</servlet-name>
<servlet-class>firstpack.JustALittleTest</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>JustALittleTest</servlet-name>
<url-pattern>/firstpack/JustALittleTest</url-pattern>
</servlet-mapping>
Under the previous error to this one I was using an entry of:
<servlet>
<servlet-name>JustALittleTest</servlet-name>
<servlet-class>JustALittleTest</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>JustALittleTest</servlet-name>
<url-pattern>/firstpack.JustALittleTest</url-pattern>
</servlet-mapping>
With the following entry:
<servlet>
<servlet-name>JustALittleTest</servlet-name>
<servlet-class>firstpack.JustALittleTest</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>JustALittleTest</servlet-name>
<url-pattern>/firstpack.JustALittleTest</url-pattern>
</servlet-mapping>
I get an error of 'Error allocating a servlet instance'

"servlet-name" is used to link the definition to the mapping.
defs are grouped together in web.xml, as are mappings.
"url-pattern" refers to the path by which you'll access the servlet.
it can any unique url on your system, and does not have to reflect the
class name.

I made the servlet part of a package but I'm getting a Servlet not
Found Exception. The actions I took to make the servlet part of a
package are the following:
1 added package line to java code, recompiled
2 placed new class file in new subdirectory of WEB-INF/classes folder
with same name of package
3 changed entry in web.xml file to reflect package that servlet is in
for the url-pattern
4 changed JSP so that the forms action="firstpack.JustALittleTest"
I've looked at the log files but I'm not sure what to look for.

I would check in tomcat logs directory for reasons why the servlet is
not available. One reason could be that classes should be in a
package:

Did you reload the webapp after making the change? All changes to
WEB-INF/web.xml or files in WEB-INF/classes and WEB-INF/lib will
require a reload before they become active in tomcat.

And my action attribute="JustALittleTest".

Subject: Accessing a servlet
Well I'm ticking these newbie questions off. I have a simple
servlet
that I want my form to access. I compiled the file fine and it is
called JustALittleTest.class. I placed this file in the
ROOT/WEB-INF/classes folder. In my JSP I have a form with some
submit buttons. The action element of the form is set to
="JustALittleTest".
I changed my web.xml file so it now has the following entries:
<servlet>
<servlet-name>JustALittleTest</servlet-name>
<servlet-class>JustAlittleTest.class</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>JustALittleTest</servlet-name>
<url-pattern>/JustALittleTest.class</url-pattern>
</servlet-mapping>
I've tried a few changes to the above entries but I haven't gotten
it
right yet. Should the servlet-class value have a .class extension?
Is
my url pattern accessing the correct folder?
