Re: [cobalt-developers] NullPointerException running JSP samples in Cobalt RaQ4 tomcat in

Martin,
Your problem is right in front of you, you have a null pointer on line 66. Go and look at your code, becuase there is something that is supposed to have/return a value but instead is returning a null pointer. 

Check out your code again.

Good luck.

Hi,

I'm pulling my hair out over this...


Set up is
Cobalt RaQ4
Sun Cobalt Developer Kit for Java (jdk 1.3.1 tomcat 3.2.1)

I have two tests that fail:
All samples in webapps/examples
An html file call test.jsp in webapps/examples/jsp/ (file contains just
html)

The jsp seems to compile find, but fails like this:
java.lang.NullPointerException

The only config mods we have made following standard installation of the
package is in workers.properties - set java_home tomcat_home and ps 

Turning on full debug info, the test.jsp gets compiled like this:
2001-09-01 09:03:56 - Compiling with: -encoding UTF8 -classpath

Any help much appreciated
