[webkit-dev] Webkit plug-in on Linux

Hi everybody, I am trying to develop a small plug-in on Webkit for LINUX using NPAPI's. I copied a sample plug-in from mozilla webiste for plug-in. I compiled and installed the plug-in in mozilla's plugin folders. When I try to execute using Webkit, its able to detect the plug-in , but i am not able to call any Javascript function which in turn executes the native code. Its giving an error like: console message: file:///home/simplePlugin/test.html @28: TypeError: Result of expression 'embed.Open' [undefined] is not a function. This is when I try to call the JS function Open. Is there any way to solve this issue? Thanks and Regards, Rekha
