I'm running Tomcat 5.0.19, under webapps I've a folder called MyApp containing my jsp files and beans.

location of my files:
%CATALINA_HOME%\webapps\MyApp\clock.jsp
%CATALINA_HOME%\webapps\MyApp\Web-inf\classes\TheBean\ClockBean.java

my setting:
set JAVA_HOME=C:\j2sdk1.4.2_04
set CATALINA_HOME=C:\jakarta-tomcat-5.0.19
set PATH=%PATH%;C:\jdk1.4.2_04\bin;

I try to use the ClockBean in my clock.jsp but i got the error from tomcat, what's the problem? btw, my OS is windows 98, would that be the cause of the problem?

The problem is that Tomcat's compiler needs the TheBean package available in the classpath to successfully compile the JSP. This is the problem.

You need to place your TheBean package in the WEB-INF/classes/ directory so its in Tomcat's classpath. So your Clockbean class will be located:

I tried possible solution posted above, but i still got the same error report from tomcat.
But I noticed something when I startup Tomcat, a message:

INFO: Installing web application at context path /MyApp from URL file:C:\jakarta-tomcat-5.0.19\webapps\MyApp
Apr 19, 2004 7:54:54 PM org.apache.catalina.startup.ContextConfig applicationConfig
INFO: Missing application web.xml, using defaults only StandardEngine[Catalina].StandardHost[localhost].StandardContext[/MyApp]

I have the web.xml file under %CATALINA_HOME%\webapps\MyApp\Web-infHere I included the web.xml file

web.xml
====================================
<?xml version="1.0" encoding="ISO-8859-1"?>

What could be the problem?

change the folder 'web-inf' to 'WEB-INF' within you application folder.
ie
CHANGE
%CATALINA_HOME%\webapps\MyApp\Web-inf\classesTO
%CATALINA_HOME%\webapps\MyApp\WEB-INF\classes
the damn thing is case-sensitive !!!

even i had a hard time finding out this one ;-(

happy deploying.

Also, if you bean is part of a package the .class file I believe should be place in the last directory for name of your package
.

Hi i am also havign ghe same problem and all the things i ahve tired does nt work....canybody can help

Hello, I had a similar problem, in my case it was caused my an error with the package, I had to create the folder for the package within a compiler so that package files were created. The directory structure I used was the same as that of the original poster of this thread:

\webapps\DBTest\WEB-INF\classes\params\validateUser.java

Where params is the package.

Other problems I had were within the jsp itself, the tag below is working:

<jsp:useBean id="valUser" scope="page" class="params.validateUser" />
<jsp:setProperty name="valUser" property="*" />

And to use the bean later on:

if (valUser.getValidation(userName[0], passWord[0]).equals("false"))

Im pretty new to this so Im not sure how much help this will be.
