servletrunner gives NoClassDefFoundError

[Wilhelm Schnell]

Running servletrunner under Windows/NT 4.0 and trying one of Suns demos
I always get the following Java exception:

java.lang.NoClassDefFoundError: javax/servlet/http/HttpServlet
at java.lang.ClassLoader.defineClass0(Native Method)
at java.lang.ClassLoader.defineClass(ClassLoader.java:360)

.java:121)

In my CLASSPATH I have the servlet.jar file specified, where the
HttpServlet.class
is included. I am using JDK1.2beta3.

Anyone else encountered this problem and got a workaround?

Thanks in advance.

Yup. I found it in the JavaSoft Bug Parade. Interestingly the workaround
was supplied by a non-JavaSoft employee, because the JavaSoft guys said
we'd have to wait for the next release :(.

It's a known bug in JDK1.2beta3. Instead of using servletrunner, try
typing...

java sun.servlet.http.HttpServer -v

... and you'll be away.
