Calling a servlet (in Tomcat) from a JSP Page (in Apache)

I have a web form in my JSP Page, which upon submits, will send the params to a servlet. The servlet will then process the request and send the results back to the calling JSP Page.
with that above senario, is there any way for me to reference a servlet (resides in Tomcat) from a JSP Page (resides in Apache HTTP Server)?
Thanks!

Apache HTTP server isn't a servlet/JSP engine.
Your JSP runs on Tomcat, right where the servlet does. Apache just forwards the request.

Is Tomcat 4's jsp:plugin tag hardwired to 1.2?

Is Tomcat 4's <jsp:plugin > tag hardwired to version 1.2 of the JPI?
I was absolutely horrified today at a job interview when, proudly navigating to the page containing the 1.4-demanding applet I embedded in the page using <jsp:plugin ...> the plugin installation dialogue came up -- asking whether they wanted to install the 1.2 plugin (up until recently, I had the applet's object tag embedded manually... switching to jsp:plugin was fairly recent).
As it turns out, the <object> tag generated by Tomcat was specifying the download path for the 1.2 plugin, even though I specified jreversion="1.4" in the <jsp:plugin> tag:
<OBJECT
   classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
   name="theApplet"
   width="550"
   height="400"
   align="middle"
   codebase="http://java.sun.com/products/plugin/1.2.2/jinstall-1_2_2-win.cab#Version=1,2,2,0">The "clsid" value can be changed in web.xml by changing the jsp servlet's "ieClassId" initParam, but as far as I can tell there's NO mechanism for changing the "codebase" value anywhere.
Is the <jsp:plugin> tag (under Tomcat 4, at least) just useless for Applets that must have 1.4, or is there a configuration parameter somewhere to set the "codebase" value generated by the tag?
I know I could always put the manually-specified code back in, but I'd prefer to stay with the <jsp:plugin> tag if possible just because it makes the jsp source cleaner. What's strange is that nobody seems to have complained about that problem on the usual places (Usenet/dejanews/Google, jguru.com, etc). Whether that's just because nobody writes applets that actually demand 1.4, or whether everybody who does just embeds the <object> tag manually, I'm not sure.
In any case, I'm trying to figure out how to make <jsp:plugin> generate the right HTML for 1.4-using applets... or whether it's even possible.

Sigh. I found it. It's actually specified as the "iepluginurl" property of the <jsp:plugin> tag.
<emotion:frustration variation="anger">
Now I just need to figure out what *$%!# value to use for it.
The JPI's developer guide has to be the worst document I've ever seen from Sun. Normally, Sun's documents are good. Often, exceptionally so. But the JPI guide... well, after reading http://java.sun.com/j2se/1.4.1/docs/guide/plugin/developer_guide/using_tags.html multiple times, I'm still not sure what #$%^&* URL corresponds to "The newest released JPI equal to or newer than 1.4.0". The only URL on the whole page that they even imply works is hardwired to 1.4.0, and in the same breath they imply that every other codebase URL on the page is wrong, hypothetical, and shouldn't be used... oh, and for that matter, the 1.4_0 one shouldn't really be used ether, because it might change in the future. Grrrrr.
If there's a pattern to the following URLs (all used on the same page) that's supposed to illustrate something besides abyssmally bad editing and apparent indecision, I haven't seen it yet:
http://java.sun.com/products/plugin/autodl/jinstall-1_4-windows-i586.cab#Version=1,4,0,0
http://java.sun.com/products/plugin/1.4/jinstall-14-win32.cab#Version=1,4,0,mn
http://java.sun.com/products/plugin/autodl/jinstall-1_4-windows-i586.cab#Version=1,4,1,mn
http://java.sun.com/products/plugin/autodl/jinstall-1_4_0-win.cabHmmm. Let's see here. They're all the same up to http://java.sun.com/products/plugin, but from that point one diverges into /1.4/, while the others continue into /autodl/. But even past that point, two imply that the filename follows the pattern jinstall-1_4-windows-i586.cab#Version=1,4,x,* ... but whether developers who really, truly, don't care about the specific maintenance release should use "0" or "mn" is left up in the air.
Furthermore, the ONE URL on the entire page that they come halfway close to implying will work is the last one I listed above, which itself goes totally against whatever hypthetical pattern they were trying to imply with the other three. For now I'll probably stick the last one listed as the parameter because it's the only one they actually come out and say will work, but I suspect the first one is probably the "right" one.
Of course, there's always the matter of Macintosh users running IE. Or Windows users running Mozilla (which is technically Netscape, but uses MSIE ActiveX plugins). Does Mozilla get fed the value of "iepluginurl", or the value of "nspluginurl"? Sigh.

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

Question concerning Eclipse and Tomcat Plugin and JSP

I have a Tomcat-Project that I am working on in Eclipse and quite a few external JARs. Everything works fine, when I run my Test class within my project (in Eclipse). But as soon, as I am trying to call the jsp in my browser I get Exceptions: "java.lang.NoClassDefFoundError: org/apache/log4j/Logger" for example, which tells me that in the browser it can't find the JARs... I'm guessing something's wrong with the classpath but I was thinking that Eclipse would handle those things for me...
I've added the JARs to my project via Eclipse (Properties -> Java Build Path -> Libraries -> Add external JARs). And I've created a subdirectory for my jsp files and allowed my project to update the .xml file for the settings and all... Do I need to do anything else? What have I done wrong so far, have I forgotten to do?

I solved the problem...

Tomcat not loading jsp pages

I've running 10.6.2 with default install of Tomcat and Apache. Tomcat is enabled in Server Admin, and I've created a site in Server Admin that points 8080 port requests to /Library/Tomcat/webapps. And index.jsp is set as a default index file.
When I try and go to myserver:8080/mysite the browser loads the jsp as text. Just like I'd opened it in a text file.
I've removed the site folder, and uploaded a new war file (which works on my local 10.6.2 client machine with Tomcat 6.0.24 installed), and a new site folder is created as expected. But the jsp page just doesn't load correctly.
What am I missing (besides years of Tomcat and Apache experience..)

hey.. noticed one more thing.. stuff works when i put
it in my file:///var/lib/tomcat-5.5/webapps/ROOT/
folder .. so i think i havent set my user properly..
any pointers??I don't think you should be putting stuff in ROOT.
Create your own web context and put it under /webapps.

Tomcat 5.0 JSP ServiceFactory Error

Hi,
I am running Apache 2, Tomcat 5.0, Axis on a server for deploying webservics. When I execute a command line java program it works just fine, but When I attempt to use this same code from a JSP it throws a ServiceException for ServiceFactory.newInstance at runtime. The code Find2p is common to both the Command Line and the JSP. For detail Find2p.java is listed way below.
Any insight into this error would be greatly appreciated, if more info is need I would happily add it to this discussion.

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.
Cheers,

Using TomCat to view JSP files

I've installed tomcat for the purpose of viewing jsp files.
In which folder am i supposed to place the jsp files to view them?
Also, what address am i supposed to type in my browser ( http://localhost:8080/myJspFile.jsp ?????? )
My tomcat folder is e:\tomcat
and JAVA_HOME is d:\jdk1.3
Thank you

Here is a good link for you to start from
http://www.moreservlets.com/Using-Tomcat-4.html#Try-Pages
http://localhost:8080/myJspFile.jsp
This looks right unless you have changed your port setting which the link above shows you how to change the port setting to port 80 so you dont have to type http://localhost:8080/blah it would http://localhost/blah.
You_tomcat_install/webapps/ROOT
or
You_tomcat_install/webapps/ROOT/some_dir
Anyways good luck and go to that link I gave you and it should help you out alot.

Tomcat is compiling JSP's on each request

Tomcat not opening jsp pages

I installed apache 2 and tomcat and configured them both.... i installed mod_jk as the connector
But when i open a jsp page, i get
HTTP Status 404 - /~scriptdevil/hello.jsp
type Status report
message /~scriptdevil/hello.jsp
description The requested resource (/~scriptdevil/hello.jsp) is not available.
Apache Tomcat/5.5PHP files open just fine.
How should i use it??

hey.. noticed one more thing.. stuff works when i put
it in my file:///var/lib/tomcat-5.5/webapps/ROOT/

any pointers??I don't think you should be putting stuff in ROOT.
Create your own web context and put it under /webapps.

TOMCAT 5 AND JSP

I have a application web (jsp and servlets)and when I work from LOCALHOST the jsp works correctly, but IF I access from INTERNET (NOT LOCALHOST)THE JSP DON T SHOW CORRECTLY, THE DATA THAT LOAD FROM A JAVA VECTOR (ONLY IT IS SEEN IN THE TOMCAT CONSOLE)BUT NOT IN THE JSP, I USED
<%@ page isThreadSafe="false" %>
FOR CONCURRENCY SETTINGS, but i dont know that it happens. Thanks-

I don't think the concurrency settings would make any difference.
What does the JSP actually show when you attempt to access it via the Internet? If you are not getting a page at all, then the most likely situation is that a firewall somewhere is blocking it. Another possibility is that you did not correctly configure your servlet engine to respond to that network address.
Err, for example, it is possible to configure Tomcat such that it gives one set of pages to localhost, another set of pages to www.carlos_borjas.com, and yet third set of pages to admin.carlos_borjas.com. But more commonly, people do forget that to access Tomcat directly, they need to specify port 8080. Or alternatively, you've installed Apache as well as Tomcat, but forgot to install the software module that told Apache to forward all JSP requests to Tomcat.
Or it could be that only part of your JSP page is loading, and usually we can tell you why it stopped loading if we saw the code where it stopped loading.
I can go on, there are lots of possibilities. The key question is, what is actually happening, and what are you expecting to happen?

Tomcat config problem: jsp can't find a bean class

I've been working within a JSP/Javabeans/JDBC/MySQL architecture with Windows XP and Websphere. So far everything works perfectly. Now I need to get the same project and make it run with a Tomcat server.
I've already set the Tomcat server but its not working properly. I have a problem when a jsp tries to access any class inside my project's package.
For example, when I make the next call:
<jsp:useBean id="ctrl" class="myPack.myBean" scope="page"/>
I get an error saying:
Error: 500
Location: /myproj/login.jsp
Internal Servlet Error:
org.apache.jasper.JasperException: Unable to compile C:\Program Files\jakarta-tomcat-3.3.1\work\DEFAULT\myproj\login_1.java:64: Class myPack.myBean not found.
myPack.myBean ctrl = null;
^
I believe that my problem cames when setting the Tomcat environment. So far what I have done is:
* install j2sdk-1.3.1.03
* install jakarta-tomcat-3.3.1
* install mysql-max-3.23.51-win
* set the environment variable JAVA_HOME
* set the environment variable TOMCAT_HOME
* set the environment variable MYSQL_HOME
* add the %JAVA_HOME%\bin to the PATH
* create 'myproj' directory inside TOMCAT_HOME\webapps
* create into 'myproj' the subdirectory WEB-INF\classes and copy into it the jar file with my java classes (myPack.jar).
* copy into TOMCAT_HOME\lib\apps the JDBC driver for MySQL.
* copy my project files (jsp, html, images, etc.) and its structure into 'myproj' directory.
I haven't include anything into the CLASSPATH because so far I've read that Tomcat will automatically include all the classes that are inside the directories TOMCAT_HOME\myproj\WEB-INF\classes and TOMCAT_HOME\lib\apps.
I really don't have a clue about what I'm doing wrong. I'd apreciate if anyone can help me out with this one ;) ... I thank you in advance!

Hi, it's me again!.
Since nobody replied to me I'm replying myself :D
Ok, seriously is just to let you know that I have solved my problem and I would like to tell you how I solved it ... somebody might be doing the same mistake than I was doing and could found this helpful. I just forgot to mention that I was using Tomcat 3.3.
Well, first of all let me tell you that there was nothing wrong with the previous configuration that I post in my first message. Everything is ok except that in the TOMCAT_HOME\webapps\myproj\WEB-INF\classes directory I was putting my classes as a jar file, so I deleted it and instead I put the directory myPack with its unpacked class files. THIS SOLVED MY PROBLEM!!!
First I was trying to do some complicated things editing bat and xml files, but as a matter of fact I found it's quite simple. Furthermore, I was really surprised by the performance of Tomcat. I'm relly happy for that !! ;)
Hope it works for you,
Ernesto

Restart Tomcat with every JSP change??

I hope I'm missing something obvious here...
Using JWSDP-1.2 (EA4).
Every time I make a change to the component tree by adding an <h:whatever> tag in my page, JSF breaks when I refresh.
For example, if I have the code below:
      <h:input_text id="password" valueRef="testBean.password">
           <f:validate_required/>
      </h:input_text>
      <h:command_button id="submit" label="Submit"
        commandName="submit" />And I insert this line before the <h:command_button>:
<h:output_errors for="password"/> The command button does not render.
I find that the only way to get the page to render correctly is to go to the Tomcat manager, reload the webapp, and then use another JSP to invalidate my session. Then the page functions correctly. Pretty cumbersome for someone who develops JSPs with the "modify and refresh" method.
Is this standard behavior that all of you are encountering? Will it continue to be so?

From what I learned with tryout and error, you need to force JSF to recreate the components tree for it to register modifications.
The easiest way I found was to load another page with JSF, so I made a link to another page from within the page I was testing.
Hope this help.

Changing tomcat to read jsp from database

Is there any way to change tomcat 5.5 to read the JSPs from a database instead of local disk. I have been reading the tomcat javadoc for some time but was unable to find the right classes to customize for this task.
Can you please give us a help on which are the sections that we should look into to create this feature?
THANKS!

It doesn't make sense to read a database directly from an applet. If an applet needs data from a database is should request if from the server which the applet is located on and the server should do the actual database actions.
The whole point of applets is that they require no installation on the client machine. If you have to change policy files or the like, you might as well install a Swing application. Furthermore accessing a database tends to depend on how the client is set up on the network. Any sensible network has firewall settings that block access to the database ports to any external access (and, again, if you are limiting the facility to a few internal machines then why not just install a program on them).
