I'm not quite clear on what the problem is. Your code looks correct. The form which has the "codice" input should have no action attribute -- LiveSite will insert one. The component which renders the form is the one which will receive the request parameters.

And also i have made entries regarding it in the build.xml ,enduser.bat and specified them in the classpath as discussed in the devnet_livesite_components_final.pdf.but then also iam getting the following error.
