Re: Classpath problems with tomcat on Linux 9
Figured out my problem. I wasn't placing the class file in a subdirectory of the WEB-INF/classes/. Solution: created UserData.java with package name "userdata" created directory WEB-INF/classes/userdata placed UserData.class in WEB-INF/classes/userdata Thank you all who responded, and anyone else that read this and spent more then the time to click the delete button on it. -Andy.

Re: Classpath problems with tomcat on Linux 9
Still no luck. I'm basically trying to do exactly the same thing that the "jsp-examples/checkbox" is doing and I can't get Tomcat to recognize my UserData.class file. I've tried placing my UserData.class file in every location possible, and no luck. My next step will be to downgrade to Tomcat 4 so I can at least try out the examples that are described in the Tomcat Bible (the examples don't work with Tomcat 5). Should I expect Tomcat to find my UserData.class file if I put it in webapps//WEB-INF/classes? Do I need to create a web.xml or should it find the class file without any web.xml customization? If anyone has a very simple example that I could drop in to see if it works, I'd appreciate it. I've already verified that the jsp-examples all work, but there is a lot of stuff in the web.xml that I shouldn't need for what I want to do, and finding what I need is probably where my problems lie. -Andy.

Re: Classpath problems with tomcat on Linux 9
Ah, if it was only that simple... The capital "A" is a typo in the email message, not in the actual error. I'm using IE on a WinXP box as my browser, but I sent my email from my Linux machine and I can't copy/paste between the two. -Andy.

Classpath problems with tomcat on Linux 9
I'm just getting started with my JSP and tomcat experience, and while learning how JSP works, I'm can't get tomcat to recognize supporting class definitions that I have placed in /WEB-INF/classes. Here's my setup: * tomcat 5.0.19, running on RedHat Linux 9.0 Pro * no customization to $CATALINA_HOME/conf/web.xml no customization to $CATALINA_HOME/conf/server.xml added my user account as a manager in $CATALINA_HOME/conf/tomcat-users.xml * I'm running tomcat using the $CATALINA_HOME/bin/startup.sh * I'm running tomcat as my normal login id, although I've also tried it as root just to make sure it wasn't a file permissions issue. * I'm able to use the Tomcat manager at http://localhost:8080/manager to start/stop/reload/deploy applications * The jsp-examples appear to work fine Here's what I'm trying to do: * Created the following "index.jsp" and placed it in $CATALINA_HOME/webapps/test What's your name? What's your email? * Created the following as $CATALINA_HOME/webapps/test/savename.jsp Name: <%= user.getUsername() %> Email: <%= user.getEmail() %> * Created a UserData.java file that defines a public class UserData with username and email fields as type String. Added public access methods for setUsername, getUsername, setEmail, getEmail. I compiled UserData.java using javac, and to produce UserData.class which I placed in $CATALINA_HOME/webapps/test/WEB-INF/classes. The UserData.java class does not define a package nor does it import anything (line 1 is "public class UserData") * deployed the "test" application using the tomcat manager and it shows that the application is deployed with no errors. * Using IE 6.0, I enter the url to test.jsp and it displays the form as expected. I enter a name and email value into the form and press the submit button and I get the following: HTTP Status 500 - exception org.apache.jasper.JasperException: Unable to compile class for JSP An error occurred at line: 1 in jsp file: /savename.jsp Generated sevlet error: [javac] Compiling 1 source file <...>/work/Catalina/localhost/test/org/apache/jsp/savename_jsp.java:42 symbol : class UserData location: class org.apache.jsp.savename_jsp UserDAta user = null I suspect this is a classpath issue but everything I read says that if you put your classes in /WEB-INF/classes, it will just work. There must be some basic thing I'm missing. Any help would be very much apprciated.
