Hello,

I am leanrning Liferay.
I run the sample code hello-world-portle.java that from source code for the book Liferay_in_Action.
I got errors below:

editJSP = null
viewJSP = null

Those errors come from the 2 lines below from the cole from hello-world-portle.java:

editJSP = getInitParameter("edit-jsp");
viewJSP = getInitParameter("view-jsp");

Therefore, the program produces error: "null is is not a valid include." That come from teh code below in
hello-world-portle.java:
:

if (portletRequestDispatcher == null) {
_log.error(path + " is not a valid include");

That eror cause program stop process.

Please help me how do I fix this problem?

My email address is ng.thai@comcast.net.

Thanks a lot for your help
