Jsp program on tomcat

I am having trouble with a simple jsp program on tomcat. I have one Java bean class that the jsp cannot find. It is in the classes directory under WEB-INF. I have tried it with and without my web.xml file and I get the same error.
org.apache.jasper.JasperEXception: Unable to compile class for JSP:
An error occurred at line: 5 in the jsp file: processFormData.jsp
The import Inn cannot be resolved
<%@page language="java"%>
<%@page import="Inn"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitiional//EN />"
<jsp:useBean id="inn" scope="request" class="Inn"/>
<jsp:setProperty name="inn" property="*" />Julie

Thanks. I'm not sure I understand why, but that was the problem.

Can anyone clarify my doubt in a simple JSP Program ?

when we write a simple jsp program such as helloworld.jsp does a
class file or servlet be created when we run the jsp program using a
web browser and Tomcat ? if so please tell the folder(path) in tomcat
where this class file will be located or stored .Thankq

JSPs will (usually) be compiled into class files representing Servlets, yes. But that's something that happens internally inside the application server and shouldn't concern you.
Why would you need to know where it resides? It seems like a code smell if you need that information.
If you're just curious, then look into the work directory of your tomcat.

How to run jsp program

is i can able to run my jsp program by using appache server..

To get JSP working in Apache HTTP Server you have to install Apache Tomcat.
You can either choose to run JSP's solely on Apache Tomcat, or to use mod_jk2 to link Apache HTTP Server with Apache Tomcat so that the Apache HTTP Server can forward the JSP requests to the Apache Tomcat engine, because the Apache HTTP Server really doesn't know how to compile/run JSP's.

Problem in running a jsp page on tomcat 5.0

hi....
i made a java class abc.java and then compiled it to get a java class file named abc.class in a package named pkg.
Then i copied this package in the classes folder of the WEB-INF folder in tomcat 5.0.
After that i created a jsp page in which i imported this class file. Now when i run the jsp page on tomcat 5.0 i get an error saying this:

Leads me to believe that you're compiling and targeting a java version that your tomcat installation doesn't support. What version of the JDK are you using?
Good Luck

Help needed in executing the java/jsp program from UCM .

Hi ,
I have a .jsp program running in my Jdeveloper which when executed pops a window to browse and select files and with few custom options .
But i want to execute that Program from within UCM (create a new jsp page in UCM OR provide link ? i am not sure .... ) , could anyone help on how i can execute/run the program from UCM ?
thanks in Advance
Plaxman

If your jsp makes use of jars you may want to look into using a WAR instead. You can check the WAR into content server and there is even a link on the administration page for JSP Web App Admin. Treating the JSP(s) and jar(s) as an entity may be a more successful path for you.
You can find some jsp examples and ever a war example in this directory: <install root>\samples\JspServer

How to execute CGI Programs in Tomcat Server

Hi,
I am working on executing Perl Scrtipts(or CGI programs) in Tomcat Server.
I have downloaded ActivePerl 5.8.0 6.0.3 build.I have modified some .jar files in tomcat\server\lib.
I have changed conf\web.xml to access the CGIServlet.class that is in servlets-cgi.jar.
My example.cgi is
#!c:\Perl\bin\perl.exe
print
"Content-type: text/plain\n\n";
foreach $var (
sort keys %ENV) {
print
"$var=\"$ENV{$var}\"\n";
@values = split(
/&/,$ENV{'QUERY_STRING'});
foreach $i (@values) {
($varname, $mydata) = split(
/=/,$i);
print "$varname = $mydata\n";
and my test.html is
<HTML>
     <HEAD>
          <TITLE>Environment Variables using GET</TITLE>
     </HEAD>
     <BODY>
          <FORM ACTION="cgi-bin/example.cgi" METHOD="POST">
               Press submit for a list of environment variables. <BR>
               First Name: <input type="text" name="fname" size=30><p>
               Last Name: <input type="text" name="lname" size=30><p>
               <input type="submit">
          </FORM>
     </BODY>
</HTML>
here I have changed url mapping in web.xml to cgi-bin.
The test.html produces two text fields first and last name on submit:
it accesses:http://localhost:8080/smalltownpapers/cgi-bin/example.cgi?fname=Tim&lname=Eden
this should print some environmental variables but it is producing an empty page.
Tomcat is not showing any errors or Tomcat is not at all listening.
Can any one help me to solve this and how to execute Perl scripts in Tomcat server
Thanks,
Regards
Murthy

Sorry, I've never done this. I went to the Tomcat site and pulled down the CGI docs, which you might have seen:
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/cgi-howto.html
No other help available from me. Sorry.

Problem on reload a JSP file in Tomcat 3.3.1

I have a problem about Tomcat 3.3.1
I am developing a JSP application,
but Tomcat not recompile the JSP file after i modify it.
I need to "wait" the tomcat recompile it, so i can see the change.
This make the development really difficult...
Do I miss some important step on config Tomcat 3.3.1
how to force it to detect a newer version JSP in every request ??
Thanks

I believe there is a way to configure Tomcat to do this, but I don't know what it is.
Until someone can tell you the configuration steps, here is a workaround. Tomcat keeps the Java source and class files for your JSP code somewhere under its "work" directory. Find those files and delete them, which will force it to re-compile.

How to see JSP compilation errors - Tomcat 4.1.18- JDK 1.4

Hi There,
I'm kind of new to JSP world, so once in while I forget to put a ; or I put a variable name wrong (I usualy use Eclipse to do my coding in JAVA, but the existing plugins for JSP development are still in their early stages, so there's isn't any plugin that indicates errors on JSP before deploying them).
When I try to see a JSP, if it has an error (compilation-time error), I get this message:
<--->
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: -1 in the jsp file: null
Generated servlet error:
[javac] Compiling 1 source file
<--->
This doesn't help me a lot to fix the problem, I would like to, at least, see from what line the error came from.
Help anyone?
Thank You
Pinho

This kind of errors often come from syntax error in
the jsp page.
Tomcat is not very friendly with this kind of errors.
A trick is to open the java file under the 'work'
directory and checkIsn't there any way to show the error on a page, just like a run-time error?
Maybe changing some log setting?

How to use debug my jdevloper devloped jsp applications using tomcat 4.0?

how to run with using tomcat path with browser?
can any one help?
thanks

Hi Pullareddy,
Charles' answer will work for Servlets in Tomcat, but debugging JSPs is a bit more complicated than debugging Servlets.
Here's what you need to do:
(I don't have Tomcat, so I don't know the details of Tomcat configuration files and I can't guarentee that Tomcat provides the flexibility so that you can configure it for debugging JSPs. Each application server is configured a bit differently. Hopefully you can adjust the following instructions to Tomcat.)
1. You need to replace Tomcat's JSP engine with OJSP and you need to setup debugging parameters for OJSP.
This is not specifically in the JDev documentation, but you may be able to apply the information found in the topic "Remote Debugging in OC4J".
Here are some tips:
A. You'll probably need to specify the following jars in some Tomcat config file: ojsp.jar, ojsputil.jar, xmlparserv2.jar, ojc.jar, and jdev-rt.jar.
B. The OJSP class name is oracle.jsp.runtimev2.JspServlet.
C. The debug parameters are:
debug_mode = true
developer_mode = true
encode_to_java = true
emit_debuginfo = true
jspjavacompiler = oracle.jdevimpl.jsp.JspOjcCompiler
2. You need to make Tomcat start the Java command with debugging options. (This is what Charles was talking about. One of the debug options is -XXdebug). This is in the JDev documentation in the topic "Starting a Java Process in Debug Mode". Please read that documentation help topic.
3. You need to delete any old .java or .class files which were created in the past for your JSP. If you leave old .java or .class files around, then the debugger may not be able to stop at breakpoints in your JSPs. So, be sure to clean up old files.
4. Set your project settings for remote debugging. This is on the Debugger - Remote panel in the Project Settings dialog box. You probably want either Attach to OJVM or Attach to JPDA. Which radio button you choose depends on what command line options you specified in step 2.

How to call EJB deployed on websphere from JSP running on Tomcat?

I am trying to establish communication between two app servers. I have a sample EJB deployed on Websphere and wish to call its business methods from a JSP page which is running on Apache Tomcat server. (ie) Tomcat is client to websphere. Is it possible to do? If so, what are the client Jar files of websphere that I should make available to JSP page on Tomcat? Do I need to set any Jars in Tomcat environment variables? Lood forward for your immediate help. Thanks in advance

Please see the thread
