Jsp and tomcat 4.0

Hi every body
please we want your help immediately, we want to run java file
and jsp files togather using tomcat4.0.

For a start u can keep the jsp's in the jsp folder
<webapps\examples\jsp> folder of the tomcat.As for java files
(can you specify what type) if they are java beans u have to
keep them in <WEB-INF\classes> directory.
hope this helps.

Exception notification through Email in JSP and Tomcat 5.5

Hi,
I have developed a Web application using jsp on Tomcat 5.5 web server. I want and email sent to myself if any exception occurs on the server side along with the exception.
I am not sure if it can be done on JSP or its part of Tomcat configuration.
I hope you guys could help me
Thank you

Check this page:
http://www.imagescript.com/atg/articles/jsp_j2ee/error_page_basics.htm
That explains how to set your own error page. Inside that jsp you can use the JavaMail api to send the exception as an email.

JSP and Tomcat Problem

Folks,
My apologies if this is off-topic for this forum, but I've been having this problem using Tomcat and JSP. I'm fairly new to Java.
Basically, I'm writing a webapp that uses servlets and JSP together. The servlet and backend classes all compile fine. Now, basic frontend page is called Console.jsp, and one of the commands that it runs is <%@ page import="DJUser">
Here's the problem: Console.jsp is in $CATALINA_HOME/webapp/
DJUser (and the rest of the classes I'm using) are in $CATALINA_HOME/webapp/WEB-INF/classes
When I attempt to run Console.jsp I get this error:
exception
org.apache.jasper.JasperException: Unable to compile class for JSP
Generated servlet error:
The import DJUser cannot be resolved
An error occurred at line: 9 in the jsp file: /Console.jsp

I'm running Tomcat 5.5.12 on Mac OS X 10.4. Could this be a permissions issue somehow? For right now (testing purposes only) I have tomcat running under my (non root) account.
I've been scouring the web for a while, and I can't really find anything on this. I'd appreciate any help you could give me.
Thanks!

Put the DJUser java file in a package (say com.myClasses) and recompile. Then put the DJUser class file under the WEB-INF/classes directory in the proper package structure (WEB-INF/classes/com/myClasses/DJUser). Stop and restart the server to pick up the new classes. Make sure to change the jsp import statement ( <%@ page import="com.myClasses.DJUser">)

Hi,
I agree, the basic documentation at the jakarta site is good, but needs a little polishing/updating.
Use google to do a search, and wade through loads of stuff before coming up with the answers, or this site is pretty good too!!!!!
Unfortunately, all the answers are not always forthcoming until you know which questions to ask (or the relevant words to enter into a search engine).

Problem with html:select or html:options tags using struts,jsp and tomcat

Hi
I'm updating a Struts-Project to a new layout and therefore rework all jsp Sites.
I'm also using a new Folder-Structure and update therefore my struts-config file.
My Problem now is:
Till now, we had a select-field with a code like this:
< html:form action="/timetableAction" method="POST">
< table width="53%" border="0">
< tr>
< td>< html:radio property="dauer" value="semester"
/></ td>
< html:select property="semester" size="1">
< htmlptions name="semesterList" />
</ html:select>
</ html:form>
The problem now is, that whenever I use any <html:xy> tag, the tomcat server I use can not show the page, he shows just the headers of the template, but not the
content.-jsp-File where the form would be in. He stops right in the middle of the html page, when he notices the <html:xy> tags.
And the funny thing is, that he has no problem to show a page when there is a <html:errors> within it? Why could this be? the struts-html.tld File is well included and teh Tomcat Server shows no exceptions.
Waiting for you answers and thanks

Thank you, I already got the answer in another forum

You say you have set up the environment variables, but it is not working. You may have them set to the wrong thing. One common mistake is to point JAVA_HOME at the java/bin directory rather than just the /java directory.
Another set of eyes finds small mistakes in the variables that you might not spot yourself.
So please, post:
The values of these environment variables
The path to where the products are installed on your system (ie is it c:\java or c:\j2se1_4_2 or c:\program files?
I would take another close look at that JAVA_HOME variable to make sure of it :-)

Cookie Problem With JSP and Tomcat

I have a tiny web application developed for my project thing.
I am facing a problem while maintaining sessions with Cookie. I use Tomcat 3.2.1 Web Server and JSP 1.2 Specifications for my web application.
I have created a page which creates a cookie and stores it in the client's PC, so when the same client visits the site, he can be remembered. Now while surfing the site in the same session, the site remembers the client. But once the client closes the browser and tries connecting to the site, he cannot be remembered. So I took a look into Temporary Internet Files of the client PC and found no cookie there. So where the cookie gets created and why does it disappears with the session. I have set a time limit of 1 year in the cookie.
Now is that a Problem with Tomcat or with the configuration settings of IE in the client PC?? Or something else???
Reply me Soon...

Thanks for your reply.
following is the code for how do i create a cookie...
<%
     String custno = custBean.createPreferred();
     Cookie c = new Cookie("pc", custno);
     c.setVersion(1);
     c.setPath("/");
     c.setComment("PreferredCustomer");
     c.setDomain("think_machine");
//think_machine is the name of the Web Server(Tomcat)
     c.setMaxAge(365*24*60*60);
     response.addCookie(c);
%>
And the code to read a cookie is..
     String custID = null;
     Cookie[] cookies = request.getCookies();
     for(int i = 0; i < cookies.length; i++)
          if(cookies.getName().equals("pc"))
               custID = cookies[i].getValue();
               break;
One more thing I would like to let you know, that i access this from the same PC on which the Web Server is installed. Means the Server and the client are both one and the same PC.

JSP and tomcat

hi
When i include a bean in jsp page, is it necessary that the bean be included in a package. can we include a bean which is not included in a package.
why because when i include a bean in a package it works fine. but when dont include it in a package i get error. i use tomcat 5.0 as my container.
why is this. should the bean be included in package in case of tomcat.
any suggestion do reply

You are absolutely correct. All your java classes should be in packages.
I actually think its a java limitation introduced in Java 1.4 - they no longer allow access to the unnamed package.
For full details check out: http://developer.java.sun.com/developer/bugParade/bugs/4361575.html
My suggestion: include all your beans in packages. Its not that hard is it?

and i'm using tomcat4.1.24, so if U have an idea or a tip, please help me ;)
good bye thx
PS: sorry for my poor english :-\

your error is being thrown from the Apache Jasper packages, so you might not find much useful info here, but what I'd do is check the mailing list archives at apache.org, and maybe see if Jasper has some API docs that will let you know when/why/where this error gets thrown.

Help running a simple jsp file,Tomcat 5.0.16

Hi,
This question may be addressed many many times,but do reply.
I have a Win xp operating system
Installed Tomcat 5.0.16 in it.
Next the directory structure
PS : The sampleapp directory is outside the tomcat installation directory.
E:/sampleapp
| |
ROOT WEB-INF
|
classes
|
<package1><structure> .class files (for servlet works fine!!!!)
in the WEB-INF,there is the web.xml,then sourcefiles<dir> and the lib directory which is empty.
Now the servlet files work fine.........
I have placed my MyJsp.jsp file in the above mentioned ROOT directory.
I have not done any thing with the <TOMCAT_HOME>/conf/server.xml file
and the web.xml which I have written.
When I give the following URI
http://localhost:8080/sampleapp/MyJsp.jsp,
I get the HTTP status 404- /MyJsp.jsp
description: The requested resource (/MyJsp.jsp) is not available.
Hoping that I have defined the problem specifically.Kindly show some light on this.
Thanks

Nevermind. I just found the answer. For the record, there are two ways in getting JSPs to work:
1. Precompiling the JSPs and modifying your webapp's web.xml file with the XML fragment generated in YourWebApp/web/WEB-INF/generated_web.xml;
2. Not precompiling the JSPs, but simply letting tomcat compile it on the fly on first access.
PRECOMPILATION METHOD
Go to http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jasper-howto.html. Copy-and-paste the ant script under the section "Web Application Compilation" into a file called compile.xml. For me, I save it in ~/development/compile.xml. Then compile the JSPs using the command (all in a single line):
$ANT_HOME/ant -file <PATH_TO_COMPILE.XML> -Dtomcat.home=<$TOMCAT_HOME> -Dwebapp.path=<$WEBAPP_PATH>
In my case, I cd into the directory where my app resides:
cd ~/development/HelloWorld
and then I type:
ant -file ~/development/compile.xml -Dtomcat.home=/var/tomcat5 -Dwebapp.path=.
(Note the trailing dot since my current directory is my webapp's directory itself. Also, in my case, my shell's PATH contains the path to the ant executable, so I just type 'ant' directly.)
Open the file ~/development/HelloWorld/web/WEB-INF/generated_web.xml and follow the instructions in that auto-generated file, which is: "Place this fragment in the web.xml before all icon, display-name, description, distributable, and context-param elements."
The web.xml referred to above is YOUR web.xml. In my case, it is the one in ~/development/HelloWorld/web/WEB-INF/web.xml
When ready to deploy, type:
ant dist
as usual. Deploy the .war file in the dist directory as you normally would. In my case, I do:
rm -rf $CATALINA_HOME/webapps/hello* (removes my HelloWorld webapp directory and its war file)
cp ~/development/HelloWorld/dist/hello.war $CATALINA_HOME/webapps
and wait for tomcat to unravel the war file. I can then access the JSP page based on whatever the generated_web.xml had specified. In my case, it would be http://localhost:8080/hello/sample.jsp
NON-PRECOMPILATION METHOD
Copy tools.jar from the Java JDK into tomcat's common/lib. (I found this only in the error message in tomcat's log file!! Didn't find it anywhere else!!). Do this one time only, then restart tomcat:
cp $JAVA_HOME/lib/tools.jar $CATALINA_HOME/common/lib
Restart tomcat.
Deploy your webapp as usual which will include your JSP files stored under your webapp's 'web' directory. No precompilation of JSPs is required. Then access your JSP pages such as http://localhost:8080/HelloWorld/my-jsp-page.jsp and tomcat will compile it on the fly on first access. The disadvantage is that there will be a slight delay on first access.
[Note: I am putting all this down for the record, because it took me MANY HOURS to figure all this out as the info on how to do this is not found clearly in one place!! Hope this helps others.]
My next step is to incorporate the contents of compile.xml as mentioned above, into my regular build.xml file.

JavaMail & JSP using Tomcat

Hi all
I am having a problem installing JavaMail
I have installed everything, added the mail.jar and activation.jar to my classpath, but when I try to run a JSP I get import errors:
javax.mail.*, package mail not found etc etc...
When I try to compile demos in the JavaMail directory, they compile fine.
Any ideas??
Thanks
Matt A

Your classpath? You need to put those jar files where the JSPs and Tomcat can see them, which I believe means you have to put them in a directory whose name is something like .../WEB-INF/lib.

Problem launching a jsp page with eclipse and tomcat

Hi,
I have just started using eclipse and tomcat for creating dynamic web pages. I tried to launch a jsp page after starting the tomcat server with the URL: http://locahost:8080/HelloWorld/, an error page was displayed as below:
HTTP Status 404 -/
type Status report
message /_
description The requested resource (-) is not available
Apache Tomcat/5.5.17
I didn't get any error at the console and when i just typed http://localhost, a pop up menu saying that the connection was refused when attempting to contact localhost.
I'm not sure what is the problem here. Could it be the permssion to the localhost is not granted by the system as the eclipse IDE is running using linux?
Hope someone can help.
Thanks.

Problem with JNDI and JSP in Tomcat

Hi,
Basically, what I've done is to use the Tomcat administration web
application to create the DataSource, which looks like it populated the
server.xml (see below). I then try to access the testconn.jsp, and am
getting that "Name java:comp is not bound in this Context" error.
I was wondering if anyone could tell me what I'm doing wrong?
Thanks,

Hi,
First of all, you can find alot of information about this in the forum about jsp's.
I think a good thing to do is not to put your context tag directly into the server.xml file.
What you should do is create a context.xml file with the context-tag in it, and put it in the META-INF directory of your .war file. Upon deployment to tomcat5 this file will be extracted from the war, copied to the conf\enginename\hostname directory, and it will be renamed to contextName.xml.
I think you are developing directly into the webapps directory, and I believe you should avoid that and use the deployment feature of the manager web-app or you should use the deployertool from you ide or standalone ant.
anyway, for starters try to remove the context tag from the server.xml file as described above, and check out the jsp / jdbc forums for simular problems and answers.
good luck

I have transfered the web.xml file and lib and classes folder in a WEB-INF folder and also all the JSP files. I can see he JSP file, but the 'hello worl' does not work and gives this exception!
Does any one have any idea what could be the problem?
thanks a lot
Mitra

seems the web Server code previously loaded a class only when it was used rather than when it was referenced,
ask your question in the tomcat-user mailing ! !!!

Jsp import package error after upgrading to jdk1.4.2_08 and tomcat 5.0

I am trying to upgrade the jdk and tomcat from 1.3/3.3 to 1.4/5.0.
My jsp imports worked fine prior to the upgrade, but now I get the following:
Jun 6, 2005 10:01:17 AM org.apache.jasper.compiler.Compiler generateClass
SEVERE: Error compiling file: /C:/Tomcat/work/Catalina/localhost/Print//org/apac
he/jsp\BillingPrompt_jsp.java [javac] Compiling 1 source file
C:\Tomcat\work\Catalina\localhost\Print\org\apache\jsp\BillingPrompt_jsp.java:11
: package com.adware.print.database.inquire does not exist
import com.adware.print.database.inquire.*;
^
1 error
A fatal error has occured for user: Unable to compile class for JSP
Generated servlet error:
C:\Tomcat\work\Catalina\localhost\Print\org\apache\jsp\BillingPrompt_jsp.java:11
: package com.adware.print.database.inquire does not exist
import com.adware.print.database.inquire.*;
The package in the import statement "import com.adware.print.database.inquire.*" actually has no classes in it. The classes are contained in "import com.adware.print.database.inquire.controller.*". If I change the import statement everything works. The problem is that I have 100s of jsps. If there is a work-around outside of changing the import statements, that would be best.
Can anyone help? Thanks.

do you know what url is being looked up? the message is complaining that the url is starting with the string "an]", which seems pretty bogus.

Jsp and tomcat 4.0
