How to DEPOLY servlet to TOMCAT

Hi,
I try to run Servlet from TOMCAT, but it has error. Please give me some help!
The Servlet is to access Oracle DB. V8i. from the Travel DB that I download from Oracle site. I use Jdeveloper 3.1.1.2 to create this project. It compiles and runs fine in Jdeveloper. When I try to deploy it to TOMCAT, it has the following error message:
Error: 500
Location: /examples/servlet/test/test
Internal Servlet Error:
java.lang.NullPointerException
at java.lang.ClassLoader.resolveClass0(Native Method)

at java.lang.Thread.run(Thread.java:484)
It looks to me like Tomcat cannot fine the lib files.
Also, the test.jar deployment file has sub directory. If I unzip them to F:\tomcat\jakarta-tomcat-3.2\webapps\examples\WEB-INF\classes, it will create several sub directories and jar files. How can I run the test.class file, if the file is in a sub directory say myproject? Can Tomcat get the lib and attachment file from all the sub directory?
Thanks very much.

You need to include the Oracle db jars (see your project properties) in your tomcat enviroment..
This is done on Windows by changing the classpath section of tomcat-dir\bin\tomcat.bat. On Unix this is done simply by dropping the jar file in the tomcat-dir/lib directory.

How to Run servlet in Tomcat 5.5.9

hi
How to run servlet in tomcat 5.5.9?how to set context path in server.xml of conf folder in tomcat since there is no context tag in server.xml.
Jiten

Hi ! I have a similar problem, well, it's along the same line ...
I'm using NetBeans 4.1, and i've coded a servlet. Using NetBeans to launch my servlet (with the bundled Tomcat 5.5.7) works fine, however i need to deploy my application unto a Tomcat 5.5.9 server.
Thus, i copied the WAR file generated by NetBeans into the Tomcat 5.5.9 webapps directory, and Tomcat expands it.
Problem is when i run my JSP pages with the form tags, they do not work on the Tomcat 5.5.9 environment. Anyone knows why?
(These work on the NetBeans Tomcat bundle 5.5.7)
My form action :
<form name="index" method="get" action="PageServlet">
My web.xml :
<servlet>
<servlet-name>PageServlet</servlet-name>
<servlet-class>application.PageServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>PageServlet</servlet-name>
<url-pattern>/PageServlet</url-pattern>
</servlet-mapping>
I'm really stumbed on why it doesn't work in Tomcat 5.5.9, any help is greatly appreciated, thanks in advance ^_^

How to run Servlet in Tomcat 5.5.7 Server

Hi,
How to run Servlet in Tomcat 5.5.7 Server. I mean where I should copy my *.class file.
Thanks in Advance.
bbye.

In order to complile the servlet you need to tell java where to find the servlet libary (as stated above by setting the class path). or (much easier IMO)
copy the servlet-api.jar to
JavaInstallDirectory\jre\lib\ext

thanks in advance i am working hard on that but
notable to get the solutionbtw by reading the documentation of tomcat and tutorials of jave on the java site (here), you would have known this!

I have Tomcat version 4.0 installed on my machine. If you look at the directory where you have Tomcat installed, you should find the directory structure:
tomcat-folder/webapps/root/web-inf/classes
Try placing your class files in the classes folder.

How to execute servlets in tomcat?

Hi,
I have compiled servlet file and tried to execute that file from root i.e. (http://localhost/'filename'....)as class file is in web-inf/classes.But it is executing from "http://localhost/servlet/" where is that servlet directory?
why all servlets executes from "servlet/" directory?
Please reply....
Thanx in advance.

I has the same problem, and my solution was to include a line in the tomcat-auto file foreach servlet i had.
Under
JkMount /MyApp/servlet/* ajp13
I set a line
JkMount /MyApp/MyServlet ajp13
and in the web.xml of my webapp i included a servlet mapping for the servlet:
<servlet>
<servlet-name>MyServlet</servlet-name>
<servlet-class>MyPackage.MyServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>MyServlet</servlet-name>
<url-pattern>/MyServlet</url-pattern>
</servlet-mapping>
Then restarting tomcat and apache it worked.
One question i have is that tomcat-auto file it is supposed to be auto-generated by tomcat, but in my case it is not, each time i add an app in the webapps dir i have to add all the stuff in tomcat-auto file. Does anyone know how to autogenerate this file?

but when i tried to run it the after submitting the page (Contact.jsp) i found one erro in the IE "The page cannot be found".
So any can help me out where i am wrong after looking the code.

Too much unformatted code for me to browse through, use code tags please.
One thing struck me though:
>        <url-pattern>
MailServlet
</url-pattern>
</servlet-mapping>
</web-app>should probably be:
<url-pattern>
   /MailServlet //notice the /
</url-pattern>Have you tried accessing the Servlet by typing out the URL? Does that work?

To start, make sure you have specified the servlet and mapping in your application's WEB-INF/web.xml file.

<servlet>

    <servlet-class>path.to.Servlet</servlet-class>
