How to get javax.comm API?

I'd recently downloaded a project on SMS sending, but when I tries to compile the code it gives error on line i开发者_运维知识库mport javax.comm.*;.

Can anybody tell me where to find javax.comm and where to place so that there will be no compilation error.

In order to ensure there is no compilation error, place the file on your classpath when compiling (-cp command-line option, or check your IDE documentation).
