Hi All,
I am developing a web application using JavaBeans (MailBean.java) inside a JSP Page with Apache Tomcat/4.1.18-LE-jdk14 and J2sdk1.4 and i keep on having the error "Unable to compile class for JSP" see full error msg below.
Meanwhile My catalina_home directory is d:\Tomcat and it has no \lib subdirectory rather there is a \common\lib directory
However, My JSP code and JavaBean file (MailBean.java) are all stored in my subdirectory called \kenTest which is in the directory d:\Tomcat\webapps\ROOT directory, and I am using the ROOT context

HTTP Status 500 -

you need to compile your bean and then place it inside /yourcontext/WEB-INF/classes

Thanks Tim, i already did that and it still is not working.
I even shutdown Tomcat and restarted yet it will not work.
My context is D:\Tomcat\webapps\ROOT
And my MailBean.java and class files are stored in a subdirectory in the path D:\Tomcat\webapps\ROOT\kenTest
I further created the directories /WEB-INF/classes and placed my compiled Bean within this folder yet that error persist, what next PLEEEE...EESE?

Well, ROOT already has a WEB-INF so Tomcat does not even recognize your new directory. If you want your application to live under ROOT, your classes will have to be in ROOT/WEB-INF/classes.
Also, be sure your bean class is in a package, and be sure your JSP imports that package.
You should download the full servlet and jsp specifications from Sun and study how web applications are suppoesd to be laid out.
