[appengine-java] Problem switching to 1.4.0 - JSP compilation fails
Hello, I'm having trouble switching to 1.4.0 SDK. Development server starts regularly, but when I try to load my login page (a jsp file) I get the following error: [WARN] /_ah/login_required org.apache.jasper.JasperException: Unable to compile class for JSP: An error occurred at line: 1 in the generated java file The type javax.servlet.jsp.PageContext cannot be resolved.

Is anyone facing the same? Do you know if there's any configuration I have to check to see if everything's fine? I'm running on Ubuntu, Eclipse Helios, GWT 2.1.0 and of course GAE 1.4.0 (from 1.3.8), Google Plugin for Eclipse v.1.4.0.

We're reproduced this. It seems to happen when you map a URL to a JSP, and only on the development server. -- Ikai Lan Developer Programs Engineer, Google App Engine Blogger: http://googleappengine.blogspot.com Reddit: http://www.reddit.com/r/appengine Twitter: http://twitter.com/app_engine On Thu, Dec 9, 2010 at 8:36 AM, l.denardo wrote: > Hello, > I'm having trouble switching to 1.4.0 SDK. > > Development server starts regularly, but when I try to load my login > page (a jsp file) I get the following error: > > [WARN] /_ah/login_required > org.apache.jasper.JasperException: Unable to compile class for JSP: > > An error occurred at line: 1 in the generated java file > The type javax.servlet.jsp.PageContext cannot be resolved.
