Debugging Servlets on Tomcat server on Eclipse IDE?

Hi,
I am new to servlets. I want to debug my servlet. It consists of doPost() and doGet methods. Is it possible to debug it ? If yes, how?
Regards,
ap.

too many cooks may spoil the broth dear APs..
any ways..sop is System.out.println(), which is the easiest way to debug.:) not a sophisticated way tho..
U can configure a logger using logger utilities like log4j.

Java servlets and Tomcat server

Hi friends
i am using Sun One forte Community edition . i am trying to make a hello world servlet .
there are 2 Files one is Index.html , HelloWorld.java (Servlet)
I call this servlet from the index.html file.
evertime i call it it gives me and error of Apache tomcat file not found .The tomcat server is inbuilt with the Sun One studio.
the directory structure is
-----HOME
-------WEB_FOLDER
----------Index.html
----------WEB-INF
-------------CLASSES
-----------------myServlet (package)
---------------------HelloWorld.java
-------------LIB
The problem is I am not getting how to write the path of servlet in index.html to call the helloWorld servlet.

Make this entry in your server.xml file located in tomcat_dir\conf.
<Context path="/abc"
     docBase="webapps/abc"
     crossContext="true"
     debug="0"
     reloadable="true"
     trusted="false">
</Context>
Suppose i want to develop my servlets in another folder Let it be "XYZ".Then your package statement must be, 'package xyz;'. Place all your servlets in webapps/abc/WEB_INF/classes/xyz dir.
Place all your Jsp(s) and Htmls in webapps/abc/pqrs dir.
Now they all come under one context 'abc'.

Tomcat error when run through Eclipse IDE :- java.util.MissingResourceExcep

Friends,
I get the following error while running the tomcat from my eclipse IDE(com.sysdeo.eclipse.tomcat_3.2.1) .
If i try running my tomcat with an application through the command line , it runs fine .... can anybody please guide .?
The error is as follows :-
[b]
Can't find bundle for base name EnvironmentResources_XXXXLocalhostDev, locale en_GB
java.util.MissingResourceException: Can't find bundle for base name EnvironmentResources_XXXXXxLocalhostDev, locale en_GB

Putting the driver into [TOMCAT]/common/lib is sufficient.
The error I think is not related to finding the driver, but actually not retrieving the correct connection string info.
I never had much luck putting this definition info into server.xml
I have had success putting it into a custom context.xml file for a web app as described [url http://tomcat.apache.org/tomcat-5.5-doc/config/context.html]here
in individual files (with a ".xml" extension) in the $CATALINA_HOME/conf/[enginename]/[hostname]/ directory. The name of the file (less the .xml) extension will be used as the context path. Multi-level context paths may be defined using #, e.g. context#path.xml. The default web application may be defined by using a file called ROOT.xml.
eg [TOMCAT]/conf/catalina/localhost/DataSourceExample.xml
Hope this helps,

Urgent :How to Start the JavaBean in the start up of Tomcat Server

Hi All
1. I need JavaBeans to be Started at the time of Starting of the Tomcat Server where i am Storing some global Database values in Hashtable collection.
2. I dont want to show the full address like http://domain.com:8080/mypath/jsp/file.jsp
how to reduce the path http://domain.com/file.jsp .. i don't want to show the full path (port number, where i am storing the files
3. when the user type http://domain.com:8080/mypath/jsp/
it shows all the files under that directory.. i dont want to show the direcotry content to outside user .. how to restrict that.
thanks and regards
sreekant

i want to start some jsp files at the start of the
tomcat server.
in some IDE i saw an option like "when start up"
i want that type of facility to my site for loading
global variables to all the web pages.1) JSPs have to be hit by something (some kindof request or dispatched request) so "starting jsp files" isn't quite the right mechanism.
2) The servlet spec provides 2 ways to load things on startup:
i) the <load-on-startup> tag in the web.xml for loading a particular servlet when the particular application loads
ii) The ServletContextListener interface and the corresponding <listener> tag in the web.xml. If your initializing is non-web specific (e.g. logging, starting up some kind of service, initializing global vars) than this is the better (and easier) route to take.
If you want to put these in the root context to happen when tomcat starts, then you'll have to make these modifications to tomcat's root web application (ROOT in the webapps folder).

Building Tomcat source under Eclipse

Hallo, all
I want to study tomcat code and build Tomcat source under Eclipse IDE (Windows, JDK 142). I have readed the Guide on Tomcat web http://jakarta.apache.org/tomcat/tomcat-5.5-doc/building.html
and downloaded the build.xml and try to run ant, ant will download needed package， i got the same error all the time, seemed that i do not have a CVS client? Who can give me some idea about building tamcat under eclipse, thanx!!!
checkout:
[echo] If the checkout fails, run `cvs -d :pserver:[email protected]:/home/cvspublic login` and try again. Th
password for the anonymous CVS access is `anoncvs`
[cvs] Caught exception: CreateProcess: cvs -d:pserver:[email protected]:/home/cvspublic -q -z3 checkout -P j

Go: Right Click on My Computer (on your desktop) -> Properties -> Advanced -> Environment Variables
You should have JAVA_HOME set to something like C:\j2sdk1.4.1_05 and CATALINA_HOME set to something like C:\jakarta-tomcat-4.1.27. You don't need to set a classpath.

How can i avoid restarting tomcat server when servlet is modified?

please advice me that how can i avoid restarting the tomcat server, whenever a servlet file is modified in my application. is their any way ?

No probs. Here's how I do things...
1. Install tomcat as normal (e.g. I install to C:\Apps\jakarta-tomcat-5.5.4)
2. Create a webapps directory in your eclipse project with the following directory structure
MyEclipseProject
   - src
   - conf
   - webapps
      - MyApplication
         - META-INF
         - WEB-INF
            - classes
            - lib
            - pages3. Set the project's output folder (e.g. bin folder) to webapps/MyApplication/WEB-INF/classes
4. Put all your jar files in the lib directory
5. Put JSPs / HTML in the pages directory (you may also want to create additional directories for TLDs, config files etc)
6. Ensure your web.xml is in the WEB-INF directory
7. Although it isn't essential I create a context.xml file and store it in META-INF, e.g.
<Context reloadable="true">
    
     <WatchedResource>WEB-INF/web.xml</WatchedResource>
     <WatchedResource>WEB-INF/conf/struts/struts-config.xml</WatchedResource>
     <WatchedResource>WEB-INF/conf/struts/tiles-defs.xml</WatchedResource>
     <WatchedResource>WEB-INF/conf/struts/validation.xml</WatchedResource>
</Context>I use this to set monitored resources that will trigger an automatic appliation reload and to configure JAAS (not shown). See the Tomcat documentation for additional information.
8. In the 'conf' directory I create a server.xml file used to configure Tomcat (you can copy the one from your <TOMCAT_HOME>/conf/server.xml).
After copying the file change appBase attribute in the host element to be the full path to the webapps directory. You can also change the HTTP and HTTPS ports if you wish
9. Download and install the Tomcat Launcher plugin from Sysdeo.
10. In Eclipse's Preferences menu you will see a new entry for Tomcat. Click this then
a. Set your Tomcat Version
b. Set your Tomcat Home
c. Set "Context declaration mode" to server.xml
d. Set the configuration file to the full path to your server.xml file created in step 8
On the "Advanced " sub page select all relevant projects to add to the Tomcat classpath
On the "JVM Settings" page add all the jars in your WEB-INF lib directory to the class path
On the "Source Path" page select all relevant projects
Now if you start Tomcat using the Tomcat icon, you will be able to remote debug your application. If you change web.xml (or any other file in your context.xml watched resources) it will automatically reload. Any changes to JSPs will automatically be picked up (providing your tell your browser not to use the page in cache - e.g. CTRL+F5 in IE)
There are some limitations that I'm still working on however. Primarily that I haven't included the Tomcat Manager application in my webapps directory, so Sysdeo cannot perform a reload. This means that if I change a source file, and eclipse auotmatically rebuilds, Tomcat doesn't pick up the change unless I either change a watched resource file (e.g. web.xml) or stop and restart Tomcat.
There's no reason why this can't be fixed, I just haven't got round to it yet.
I'm sure there are lots of other (probably better) ways of achieving the same thing. This was the first method I tried and it worked, so I stuck with it. I'm not a Tomcat config guru and I'm sure other forum users could provide some improvements should they wish.
Post if you get into trouble, however I won't be able to respond until next week.
Cheers,
Steve

Running Tomcat server in Debug mode?

Hi..
I am using Eclipse IDE to develop a Portal project.. I am also using Tomcat server for the same without using the default servers provided by eclipse..
My question is how do I run the Tomcat server in the "debug" mode?
Please help me..

Take a look at these links: http://plato.acadiau.ca/courses/comp/dsilver/2513/EclipseAndTomcatTutorial/
http://www.keyboardsamurais.de/2004/01/15/tomcat_tutorial_helloworld_for_complete_fools_-_english/
http://www-128.ibm.com/developerworks/opensource/library/os-ectom/?ca=dgr-lnxw16EclipsTomcat
I've found going through tutorials is a proven, quick way of getting up to speed with new tools and configurations.

{Q} Debuging Servlets with VCafe 4.0 using WebLogic as WEB server

Hi,
          I am trying to set up VCafe 4.0 to debug servlets deployed on WebLogic 5.1.
          I don't have any problem with default servlet debugging, but I don't know

What edition of VCafe is required?
          Enterprise, Professional or standard. I am now using JBuilder and anyone has
