Netbeans 6.1 Rest JSR-311 RI library problem

Found a minor problem with Netbeans 6.1 and Rest (Jersey RI) today, thought I'd capture the problem and solution.

Symptom: Can't launch a Rest application using Jersey (JSR-311 RI) libraries - error given is:

HTTP status 500

exception

javax.servlet.ServletException: java.lang.NoSuchMethodError: javax.servlet.jsp.JspFactory.getJspApplicationContext(Ljavax/servlet/ServletContext;)Ljavax/servlet/jsp/JspApplicationContext;
 org.apache.jasper.servlet.JspServlet.service(JspServlet.java:274)
 javax.servlet.http.HttpServlet.service(HttpServlet.java:803)

Because the Jersey (JSR-311 RI) libraries include jsp 2.0 jsp-api-2.0-20040521.jar from Netbeans6.1\enterprise5\modules\ext\rest\ which is an older version of the JSP API.

Fix, copy a newer jsp in or remove the entry from the library definition and add a newer jsp library in.


Example Solution:

Go to tools\libraries
Select the Jersey libary
In the Library classpath, remove the offending jsp-api-2.0-20040521.jar
Now add the newer JSP libary, e.g. Netbeans 6.1 ships with servlet2.5-jsp2.1-api.jar one level up in the Netbeans6.1\enterprise5\modules\ext\ directory.
Remove the Jersey libraries from your project (if already added).
Re-add the Jersey libraries to your project and recompile - problem solved.
