ReplyC:\Documents and Settings\Praveen\j2mewtk\2.5.2\apps\bldis\src\Blue.java:15: package javax.bluetooth does not exist
import javax.bluetooth.*;
^
When i installed sun wireless toolkit2.5.2 it gets installed in
C:\WTK2.5.2
but when i create new project in sun wireless toolkit2.5.2 it is created in
C:\Documents and Settings\Praveen\j2mewtk\2.5.2\apps
while installing it doesn't ask path for storing new application. . . automatically it get stored in this path
C:\Documents and Settings\Praveen\j2mewtk\2.5.2\apps
i created my project in the name of bldis.
I have to use jsr82 jar file.
I simply copied this jar file to the path
C:\Documents and Settings\Praveen\j2mewtk\2.5.2\apps\bldis\src
but it show the same error.
So i extracted the jsr82 jar file and copied the javax folder and manifest folder to the path
C:\Documents and Settings\Praveen\j2mewtk\2.5.2\apps\bldis\src
again it show the same error.

I dont know how to correct this error . . .
Please anyone give me suggestions to correct this error and guidance for point to multipoint communication using bluetooth . . .
