JSP problem when running Tomcat in Eclipse

Hello,
Eclipse newbie here.
I just started using Eclipse and I have installed the Tomcat plugin. When I run Tomcat within Eclipse, http://localhost:8080 works fine, but when I tried to access a JSP that I've created, I'm getting this error:
HTTP Status 404 - /JSPDemo.jsp
type Status report
message /JSPDemo.jsp
description The requested resource (/JSPDemo.jsp) is not available.

Running Tomcat from Eclipse

Hi All,
This is the first time i am trying to run a web project through Eclipse.I have configured Tomcat for that.I have setup a project where in my servlets are created under src and the classes are compiled under the build/classes folder.
I have kept the fork option true in the Server web.xml.
My jsps are running.But when i am trying to send a request to the servlet.The mapping from the servlet is not recognized.Definitely case of a classpath.
I am not sure what classpath doest it take.Its not taking from the build/classes folder i have tried creating web-inf/classes folder and kept the class file there.But it did not work.
Please help

i need not deploy the files in tomcat as the files are being picked up from my eclipse
workspace and the necessary files are in the eclipse build path.What i think is the VM is looking for the
classes in the Tomcat folder and its not finding the classes under tomcat.

Using Tomcat in Eclipse?

Hi,
Can you tell me how to use Tomcat using Eclipse?
Whether we have to plug-in Tomcat in Eclipse?
I'm using Eclipse3.1.1 Version.
Thanks,
Hari

you can use "com.sysdeo.eclipse.tomcat_3.1.0" plugin. Just download the zip file and expand it in plugin folder of eclipse. I am using it on ecipse 3.1.2 it works fine.
By the way you need to set certain parameters in Eclispe.
GO to windows-preferences-java
Installed JREs - add the path of your j2sdk1.4.(eg.c:j2sdk1.4.2_11)
then Go to windows--preferences--tomcat-
advanced - fill your tomcat base
JVMSettings - JRE drop down box select the j2sdk you added
JVMSettings - classpath - add tools.jar from your j2sdk lib folder
JVMSettings - Boot ClassPath - add rt.jar from your jre lib folder
SourcePath
Select your java project you are working with
Then click ok.
Try to run eclipse in clear mode.
Please let me know if this worked. I also did the same procedure and It is working fine.

Like the message says, you haven't set the JAVA_HOME variable correctly.
Have you set it?
It should point to the ROOT of your java install
eg
JAVA_HOME = c:\j2sdk1.4.2_04
Are you running Tomcat through Eclipse, or on its own?

Tomcat in eclipse

How could i run the tomcat in eclipse?

If you want to run tomcat in eclipse for sure you need some additional plug-in. I use eclipse for writing wtp appications that use web-services - because of that I use very reach in plug-ins version of eclipse:
wtp-all-in-one-0.7
You can find it here:
http://download.eclipse.org/webtools/downloads/drops/R-0.7-200507290654/
With this you can write wtp applications, write web-services using axis and - of course - run tomcat.

So is context.xml actually overwriting the settings found in server.xml?I think so. The way I understand it is the the context.xml file saves you from having to edit server.xml. It is preferred for each web app to do its own config, rather than lumping them all together in server.xml.
And what would be the best way to create the war file? IAt its heart, a WAR is just a zip file with its contents laid out in according to the specification of a web application directory structure.
So the simplest way to make a war file is to zip up your directory structure with a tool like winzip, and rename it to be myApp.war.
Regarding ant, I would recommend you take a look through [url http://jakarta.apache.org/tomcat/tomcat-4.1-doc/appdev/index.html
]this tutorial. It explains the basics of website layout, configuration and deployment.
On [url http://jakarta.apache.org/tomcat/tomcat-4.1-doc/appdev/source.html] this page in particular, it includes a link to a basic ant file that you can use as a starting point.

Re: Using already running Tomcat server for development.

Hi Nick,
Yes, you can use existing Tomcat Server for debugging app developed with
NitroX. And you can refer to Help > Help Contents > NitroX User Guide >
NitroX Tour > Running and debugging the application.
We do support Tomcat 4.0.x to Tomcat 5.0.x. If you need any further
assistance please get back to us.

Sorry if this has been covered anywhere else.Just wondering if you can use an existing tomcat server for debugging

files to compile and re-deploy my apps into the running tomcat server.
Just wondering if I can do something similar thru NitroX and Eclipse.

Eroor in eclipse when i have run TOMCAT in debuge mode web service debuging

hello all,
i have a serious problem with debug my web service. I set local variable in eclipse (-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8000). And now if i run TOMCAT in normal mode all worked fine and i run remote java application fine, but if i run TOMCAT in debug mode, eclipse in console return error:
"Error occurred during initialization of VM
agent library failed to init: jdwp
ERROR: Cannot load this JVM TI agent twice, check your java command line for duplicate jdwp options."
If anyone have this problem please tell me how to resolved it.
Thank for help.

Eclipse is kind of a competing product so this is not the best place to ask the question. With that most will be nice enough to lend a hand. I suggest ensuring that all other instances of tomcat are stopped then try again. In the Debug perspective ensure there are no servers running with the same name as the one you are attempting to use. If all else fails ensure there are no tomcat process running if they are kill them. Finally, if you cant get it to work reboot. If still no good the Eclipse might be a better place to go.

Have you installed the Tomcat plugin for Eclipse? http://www.sysdeo.com/eclipse/tomcatplugin
If so, you need to create a new Tomcat project using the wizard:
File->New->Project... then choose Java->Tomcat Project
In the wizard, choose a project name, then uncheck the 'use default' checkbox in project contents and browse to your webapp's directory (within Tomcat/webapps). Then finish the wizard.
Start Tomcat from within Eclipse - you can then add breakpoints etc to debug

How to run an application i created in java without using eclipse

Im familiar with running an application i create thru command prompt or eclipse, how do i create a file to run on any computer with java so i can double click the file and my application runs. C# automatically does this, do i need to do an extra step to the jar file?

Hi,
You need to make an executable JAR file. There are a few ways you can do this but since you are using Eclipse you can follow this tutorial.
[http://www.fsl.cs.sunysb.edu/~dquigley/cse219/index.php?it=eclipse&tt=jar&pf=y]
The most important part is the manifest file, if you have dependencies on other JAR files they will need to be specified along with the
main method to call to start you program. You can do this via the Eclipse Wizard.
It will be in your interests to read this tutorial also

Thanks a lot.

The first posting was refering to a java project.
Now I tried to make a dynamic web project.
There i have the mistake:
First a pop up appears and says: Could not fid the main class. Programm will exit.
and then:
java.lang.NoClassDefFoundError: org/apache/catalina/startup/Bootstrap
Exception in thread "main"
Does anybody know how I create a project (JSP/JSF), so that I can start the page with for example tomcat.
If one of you has a toturial where there are exactly the versions written, as I did everything refering to an toturial.
Pls give advice, how to get it started.
Thanks in advance.
