Tomcat directory structure + jsp

Hi all,
I have been trying for a long time now to setup my tomcat-directory as described, but I don't get my application running... My directory structure is currently as follows:
d:\
    webapp\
         web\
              WEB-INF\
                    classes\
                         servlet
                    libThe path for tomcat is set to d:\webapp\web, where my JSPs are. From the JSPs, I start some applets - the problem is, where do I have to put them? They are in the directory project; if I put this directory in WEB-INF/classes, they are not found. If I put them directly in the web-directory, they are found, but not the classes they depend on... I can then put all the classes I need in the web-directory, and my application runs, but as far as I understood, this is not the supposed setting :-( And besides, the only reason for the WEB-INF directory would then be the servlets inside (which run without problems!)
Might I do something wrong in calling the applets? In the moment, I start them with <applet code="project/Start.class"> Or do I need to change something in the web.xml file?
Thanks for any hints,
Thea

but as far as I understood, this is not the supposed setting That IS the appropriate setting.
An applet runs on the client machine.
Therefore the client has to download all the class files to run the applet.
The client cannot download any classes that are under WEB-INF. WEB-INF directory is for the server only.
Therefore any classes needed to run your applet must be outside of the WEB-INF folder, so they can be downloaded.
JSP/Servlet code runs on the server side. The code for this you can put under WEB-INF, and it will only be available to the server. That way you have your application, but don't have the code freely downloadable.

Tomcat directory structure

Hi, I've programmed a client - server application based on an applet - servlet communication and all is running ok. I've my applet and all the classes needed by it in Root/ directory and my servlet and all the classes needed by it in Root/WEB-INF/classes/ directory. All clases have no structure. Te problem appears when I want to give a certain structure to all my classes (put them in certain packages).
For example, if my applet belongs to the packate myPackage I put it in Root/myPackage/ and if my servlet belongs to the package myServletPackage I put it in Root/WEB-INF/classes/myServletPackage/ and so on.
Finally I configure my web.xml file like this:
<servlet>
<servlet-name>MyServlet</servlet-name>
<servlet-class>myServletPackage.ElServlet</servlet-class>
</servlet>
After restarting tomcat when I try to run the application It appear a No class foun exception.
Can anyone tell me what I'm doing wrong?
Thks and sorry for my english.

Sorry for my bad example. In fact I put the Root directory as an example, It's real name is MetroNet and, as I say on the previous topic the problem appear when I try to organize my classes in different packages.
thnks

Web Application directory structure

Please can someone help me with directing me to any online guide as to how webapp could be created and web.xml configuration in Sun Application server 8.
I do not understand the directory structure of sun, unlike Tomcat the webapps contains all the virtual context part with a default ROOT direct set in the server.xml as the default docbase.
Now, where is the default ROOT in Sun server? Where can I put my index file. When I create a web context, where will I put it? Does J2EE has similar WEB-INF structure in Tomcat? Does it have web.xml to configure the webapp
Finally, I have written a simple EJB called Hello World using stateless protocol. I have my Hello.class, HelloHome.class and HelloBean.class. I also have ejb-jar.xml for container configuration. I have jar then up to hello.jar and have deployed them. Now I want to access the beans, Home bean to be precises. I have written a hello.jsp and I put it in the orignal directory where the main index.html file is in Sun server which is /user/Sun/AppServer/domains/domain1/docroot, I got errors.
Could someone shade a light on this please.
Thanks Guys.
NB
Do not point me to online reference
I have awared max point for this question

The developer's guide discusses in pretty clear terms how to deploy a J2EE app from a directory structure.
The tomcat directory structure is really the same as a packaged war which once you read the documentation you will see is basically no different with SJSAS.
You need to deploy an application. See previous posts on how to have docroot be the top level (search for posts by janluehe)

Project directory structure

I'm do jsp development onto Tomcat and about 3 months ago moved to Jdev. I've set up my project to go against the Tomcat directory structure but am not sure this is the best thing to do when using jdev. Does anybody have a recommended directory structure to use for a project?

I got this worked out.

Directory Structure Problem

Hi i am niew to EJB
my directory structure is like this
App
-----JSP,s
-----WEB-INF
--------classes
-------package name
-----------servlet class file
-----PAckage Name
-----------Sesion Bean Class File
my servlet is calling the session bean but when i open this app in weblogic builder it only shows jsp/servlet related setting
what is the correct directory structure
jsp is calling a servlet which in turn calles a session bean
kindly tell me
Puneet

I don't know why but weblogic builder sometimes behaves weird. Anyway, my suggestion is to try out to edit your application.xml manually.
good luck,
Fehmi

I have a created a directory structure ias\ias-samples\myapps\src\docroot.In docroot folder i have a single jsp.i created a war file having that jsp,and ear file having the war file

I deployed the ear file.Now i try calling http://localhost/myapps/test.jsp ??
i'm i doing the right thing ?

Hi,
This is right provided you have installed the webserver & app server
on the same machine and the port number for the web server is 80 by
default.

Problem with Configuring Tomcat for running jsp web applications..Plz HELP

I am using Tomcat 5.5 and Jdk 1.5.0_12 and Oracle 10g. I am using jdbc-odbc bridge connection
to connect to the database. I have placed my project folder called
tdm under the webapps folder in Tomcat. This 'tdm' folder consists of
a collection of html pages,jsp pages and images of my project. Also I created a
WEB-INF folderand in that I have lib folder which contains catalina-root.jar

Directory structure of web sphere

i did not get the directory structure of the web sphere 6.1 to deploy a sample application like webapps->dirname->WEB-INF->classes etc in tomcat server.
The project is developed under tomcat but it has to be convert to the web sphere.

please google..

Can't I change the directory structure?

          Hello Everybody,
          So far everything is working when use the default directory structure,i.e. mydomain/applications/myWebApp/WEB-INF/classes/some package structure.
          But we have application with lot of html files which call servlets like this..myWebApp/WebApp/myServlet.
          In order not to change my html files, I've created this WebApp directory under weblogic directory structure shown above.
          I've done some trial and error in web.xml file to make servlets execute. But 404 error is showing up.
          I tried putting in web.xml like this...
          <servlet>
          <servlet-name>/WebApp/HelloWorldServlet</servlet-name>
          <servlet-class>com.reliable.servlets.HelloWorldServlet</servlet-class>
          </servlet>
          <servlet-mapping>
          <servlet-name>HelloWorldServlet</servlet-name>
          <url-pattern>/WebApp/HelloWorldServlet/*</url-pattern>
          </servlet-mapping>
          I also tried taking out slash(/) before WebApp but no luck.
          Can any one guide how to make this work.
          Thanks so much,
          Sri


What he needs is something like:
          <servlet>
          <servlet-name>HHH</servlet-name>
          <servlet-class>com.reliable.servlets.HelloWorldServlet</servlet-class>
          </servlet>
          <servlet-mapping>
          <servlet-name>HHH</servlet-name>
          <url-pattern>HelloWorldServlet/*</url-pattern>
          </servlet-mapping>
          HHH is simply to link the mapping declaration to the servlet declaration.
          Then the URL would be something like:
          http://myserver:8801/appname/HelloWorldServlet/abc
          If this is the default app, then appname/ drops out.
          There is a good discussion of this in our docs and
          the servlet spec discusses this as well.

Looking for Directory structure

Hi i am new bie to Tomcat .
i was wondering if some explain me the directory structure for a web Application.
like where to put the HTML files and where to put the Java classes and where to keep the JSP
and what is the Importance of WEB-INF dir
Thanks in Advance.

You should create a directory under the webapps and name any name, for example, name it projects and under the projects there should a WEB-INF directory which has a classes directory, under which you keep the .class files, may it be servlets or beans which are used in jsp's. And the normal html, pages from which you call either a servlet or a jsp on clicking a button or something will directly under the projects directory in our example.
for example a LoginServlet will be in classes directory, the path will be
C:\progra~1\apache~1.0\webapps\projects\WEB-INF\classes\LoginServlet.java
and you can access the LoginServlet by giving this url
http://localhost:8080/projects/servlet/LoginServlet
hope this helps

How to not let others see tomcat directory

I don't want to others see my tomcat's directory in my webapps. in other words, i want to prevent people from knowing my tomcat server directory structure by typing the url "http://202.38.248.1/Basic/"(Basic is a directory in ROOT which contain a lot of JSP pages). How to make it?

Go to where your default Servlet is defined (probably in Tomcat/conf/web.xml) and add the init parameter:
        <init-param>
            <param-name>listings</param-name>
            <param-value>false</param-value>
        </init-param>to the <servlet>
<servlet-name>default</servlet-nam>definition.

Default Directory for JSP

Using Eclipse with Tomcat 6.0 Server, I have the following directory structure:
/Project
/WebContent
webpage.jsp
/PicsI am trying to access files within the Pics directory through the JSP. I figure this should be possible by getting the JSP document's directory and calling the Pics directory from that. However, I can't seem to figure out how to do this. I have tried
new File(".").getCanonicalPath();but that returns a path to my user directory within the operating system. I feel like this should be really easy, and I feel pretty dumb being unable to figure it out (nor able to find this on Google/SDN), so if somebody could just put me out of my misery with a line or two of code (or even just the call I need to make) I would really appreciate it.
Thanks!

ServletContext#getRealPath() returns the absolute path for the given relative web path.
String absolutePathOfWebRoot = getServletContextSomehow().getRealPath("/");
String absolutePathOfPicsDirectory = getServletContextSomehow().getRealPath("/Pics");

Directory structure for a J2SE+J2EE project: suggestions are very welcome

Hi, I have to start coding and organizing the CVS tree of an already mature project which is J2SE. This J2SE project can be described as a "core engine" for something else, and is a quite large project, and up to now has only a command line User Interface. I organized the dir structure as this:
/build.xml
/src/
/src/java/<package>/...../*.java
/src/demo/<package/...../*.java
/src/test/<package>/....../*.java
when I ant compile, all the .classes will be done in the "build" directory (reflecting the structure in the "src" dir):
/build/
/build/java/<package>/....../*.class
/build/demo/<package/...../*.class
/build/test/<package>/..../*.class
I am happy with this, but now comes the issue: a web interface to use this core engine (it will have the same package namespace) is in developing progess, so I have to put somewhere the *.jsp, the WEB-INF dir with web.xml and servlet sources: how would you do this? And where would you let Ant put the compiled servlet classes?
I can modify the previous directory structure to accomodate the J2EE part, this is really not a problem!
Thanks to who can suggest me a clean solution
Alessio

Create a web-inf folder at the same level of src and
jsp folder inside src
i mean
/build.xml
/src/
/src/java/<package>/...../*.java
/src/demo/<package/...../*.java
/src/test/<package>/....../*.java
/src/jsp
/web-infSo, would you put in /src/jsp only the *.jsp?
And what in /WEB-INF ? What woud you put there? Would you do something like:
/WEB-INF/web.xml
/WEB-INF/src/<package>/..../<my_servlets_and_j2ee_stuff>.java
/WEB-INF/classes/<package>/..../<my_servlets_and_j2ee_stuff>.java
In this manner sources and classes are in the same tree, it does not seem very clean to me, expecially if you consider that probably I must have a "test" directory to unit test some j2ee stuff (as for the j2se stuff in "src"): how would you do that?
Is this directory structure anyway what you meant or not?

Directory Structure ?s for an Exploded Web Application

We have an application that consists only of JSPs and Servlets, no
EJBs. I am researching whether or not it's worthwhile to start using
EJBs. We're also migrating from Weblogic 5 to 6.1. I've managed to
migrate our application fine and have it up and running on WLS 6.1.
I'm confused about the exploded directory structure, the
application.xml file, where to put the EJBs and whether or not I have
to jar them. Here's our current directory structure:
DefaultWebApp/               JSPs here
DefaultWebApp/WEB-INF          web.xml and weblogic.xml here
DefaultWebApp/WEB-INF/classes     Servlets and other classes here
DefaultWebApp/WEB-INF/lib     do my un-jar-ed EJBs go here?
I've been reading a lot of BEA's documentation, particularly
‘Deploying an Exploded J2EE Application' and a ‘Web Application PDF',
and looking for relevant threads on the weblogic.developer.interest
groups. It looks like the application.xml should go in a new
DefaultWebApp/META-INF directory. But where do the EJBs go?
I also see some directory structures with another /web directory
that's confusing me.
Oh, I've also managed to compile and jar up a trial Stateless Session
EJB. Then I think I ‘auto-deployed' it into the /applications
directory, and Weblogic seems to recognize it. But when I tried to
reference it in a JSP, I got an error message ‘class x is public,
should be declared in a file named x.java'. I'm assuming this is
related to the application.xml, where I need to define the ejb
directory.
Thanks.

To deploy your web app together with your EJBs, you need to create
an "EAR" structure. Both your webapp and your EJB jars will be within
this new structure, at the same level. You may jar up your EJBs, or you
may explode their structure, it's up to you.
The resulting structure should look something like below:
EnterpriseApp/ <-- new top level
EnterpriseApp/META-INF/
EnterpriseApp/META-INF/application.xml
EnterpriseApp/lib/ <-- shared libraries (if any)
EnterpriseApp/EJB/ <-- ejbs go here
EnterpriseApp/EJB/META-INF/ejb-jar.xml
EnterpriseApp/EJB/META-INF/weblogic-ejb-jar.xml
EnterpriseApp/EJB/com/your/ejb/classes/here
EnterpriseApp/WebApp/ <-- move your current app here
EnterpriseApp/WebApp/index.jsp <-- JSPs goes here
EnterpriseApp/WebApp/other.jsp
EnterpriseApp/WebApp/WEB-INF/web.xml
EnterpriseApp/WebApp/WEB-INF/weblogic.xml
EnterpriseApp/WebApp/WEB-INF/lib <-- ui libraries go here
EnterpriseApp/WebApp/WEB-INF/classes <-- servlets go here
The above structure is identical to the structure to an EAR file, only "exploded"
as actual files and directories instead of being "jarred" into a single EAR file.
Your application.xml in this case would specify something like:

And in config.xml you would have an entry similar to:
<Application Deployed="true" Name="EnterpriseApp"
Path=".\config\mydomain\applications\EnterpriseApp">
<WebAppComponent Name="ui" Targets="myserver" URI="WebApp"/>
<EJBComponent Name="ejb" Targets="myserver" URI="EJB"/>
</Application>

Directory structure for the new Data Services Project

1) I do as prescribed in the manual "Building and deploying
Flex 2 Applications", page 325
"To create a web application make a copy of the /flex
directory and its contents. Rename the copy and store it in the
same location under /servers/default directory."
("flex" is an empty Flex Data Services application that
serves as a template for creating your custom application)
2) I create a corresponding project from Flex Builder 2 :
Project type: Flex Data Services
Root folder: C:\fds2\jrun4\servers\default\MyDS
Root URL:
http://localhost:8700/default/MyDS
Project name: MyDS
Project contents: C:\fds2\jrun4\servers\default\MyDS
2) I build the project
Immediately after "build project" the directory structure at
C:\fds2\jrun4\servers\default\MyDS becomes the following:
.settings
bin
----------------META-INF
----------------WEB-INF
---------------- --------------- classes
---------------- ---------------flex
--------------------------------jsp
--------------------------------lib
-------------------------------sessions
html-template
META-INF
WEB-INF
----------------classes
----------------flex
----------------jsp
----------------lib
----------------sessions
Notice that bin directory now contains another pair of
META-INF and WEB-INF in addition to those already existing in the
template project "flex".
Can anybody comment on this directory structure?
Which META-INF and WEB-INF are supposed to be used for
configuration?
What is the purpose of having two pairs of META-INF and
WEB-INF in the same web app?

Hello -
first, those folders are necessary in deployment - You need
only the contents of the bin folder for deployment, not the
sources. Since you're compiling the application locally in FB2 it
places all of the supporting and necessary files into one location
namely the "bin" folder. You'd deploy the "bin" folder's contents
to the FDS server, perhaps another FDS server that is not your
"development" server -- like a production server. The data and
configuration information that your app needs for FDS services are
stored in the WEB-INF and META-INF folders so these need to travel
with the final product. On the production server you'd just cop the
"bin" folder and it's contents to the /servers/default folder -
where you could then rename your bin folder to "MyDS"
