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).

Use RXTX.

On Debian install librxtx-java by typing:

sudo apt-get install librxtx-java

On Fedora or Enterprise Linux install rxtx by typing:

sudo yum install rxtx

you can find Java Communications API 2.0 in below link

Another Simple way i found in Netbeans right click on your project>libraris click add jar/folder add your comm.jar and you done.

if you dont have comm.jar download it from >>> http://llk.media.mit.edu/projects/picdev/software/javaxcomm.zip

On ubuntu

 sudo apt-get install librxtx-java then 

add RXTX jars to the project which are in

 usr/share/java
