I'm using NetBeans 3.3.2 with an EXTERNAL instance of Tomcat 3.2.3. I'm
trying to configure Tomcat so I can watch JSP variables and expressions.
Here is how I'm starting Tomcat:
start "Tomcat 3.2.3"
"C:\Java\1.3.0_02\bin\java" -classic -Xdebug
-Xnoagent -Djava.compiler=NONE
-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8888
-Dtomcat.home="C:\jakarta-tomcat-3.2.3"
org.apache.tomcat.startup.Tomcat
Once Tomcat is running, I can attach to it from NetBeans via dt_socket on
port 8888. I can then mount the compiled servlet in NetBeans, set
a breakpoint, and execute up to that breakpoint. What I cannot do is
watch variables or expressions. If I specify a variable to watch,
NetBeans tells me the "Identifier cannot be resolved."
At the top of the variables list in the NetBeans debugger window is
the message "source compiled without -g option." This leads me to
believe Tomcat isn't creating the servlet with the required
debugging information. I enabled the "classdebuginfo" parameter in
Tomcat's WEB.XML, but this seems to have no effect. Here's an excerpt:
<servlet>
<servlet-name>jsp</servlet-name>
<servlet-class>org.apache.jasper.runtime.JspServlet</servlet-class>
<init-param>
<param-name>classdebuginfo</param-name>
<param-value>true</param-value>
</init-param>
<load-on-startup>-2147483646</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>jsp</servlet-name>
<url-pattern>*.jsp</url-pattern>
</servlet-mapping>
Any suggestions? The application I'm using requires Tomcat 3.2.3. I
cannot use a different version of Tomcat.
