I would like to be able to use JSP debugging, however, this doesn’t appear to be an option with Tomcat 4, so I moved to Tomcat 5.0.28. When I did, I started to receive JasperExceptions like the following;

org.apache.jasper.JasperException: /provision/JspMapImage.jsp(52,0) The value for the useBean class attribute com.earthwhere.webapp.JspMapImageBean is invalid.

Everything was running fine in Tomcat 4. Looks like a classpath issue w/ Tomcat 5. Can anyone shed some additional light?

Eclipse Platform
Version: 3.0.1
Build id: 200409161125

MyEclipse
Version: 3.8.4
Build id: 200501171200-3.8.4

Thanks,
Mark

The value for the useBean class attribute com.earthwhere.webapp.JspMapImageBean is invalid.

Where does this class come from? Is the JAR in your WEB-INF/lib directory?

You might want to check your /common/lib directory of your Tomcat 4 install and see if you had put any custom JARs there that are not in your Tomcat 5 install. (custom JARs, not system JARs, don’t just copy over all the JARs, this will cause Tomcat 5 to barf).

Hi Riyad,

I’m using the exploded deployment option, the class is in WEB-INF/classes.

5.0.28 common/lib contains….
ant.jar commons-dbcp-1.2.1.jar jasper-compiler.jar naming-common.jar naming-resources.jar
ant-launcher.jar commons-el.jar jasper-runtime.jar naming-factory.jar servlet-api.jar
commons-collections-3.1.jar commons-pool-1.2.jar jsp-api.jar naming-java.jar

4.1.31 common/lib contains….
activation.jar commons-collections.jar commons-pool-1.1.jar jdbc2_0-stdext.jar mail.jar naming-resources.jar
ant.jar commons-dbcp-1.1.jar jasper-compiler.jar jndi.jar naming-common.jar servlet.jar
ant-launcher.jar commons-logging-api.jar jasper-runtime.jar jta.jar naming-factory.jar

Why wouldn’t Tomcat find it under WEB-INF/classes?

Thanks for your help,
Mark

No idea… everything looks kosher. Try and remove your deployment, rebuild your project and redeploy. Also provide the snippet of code that craps out.

Make sure that your bean have default parameterless constructor.

I’m using Tomcat 5.5.7 with the exploded package option for deployment on MyEclipseIDE for Eclipse 3.1 and JSP debuging works fine
