I'd recently downloaded a project on SMS sending, but when I tries to compile the code it gives error on line import 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).

    I'd downloaded the .zip now there is a `comm.jar` file. Did I've to set the class path to this `comm.jar` file or I will extract the `comm.jar` file? – Mohammad Faisal Sep 26 '11 at 23:51

    Just add the comm.jar to the classpath. Don't extract it. – Ryan Schipper Sep 27 '11 at 00:02

    so by putting `comm.jar` in classpath I don't need have to change the code for `import javax.comm.*;`? – Mohammad Faisal Sep 27 '11 at 00:11
  • You have to import the classes you wish to use, along with adding comm.jar to the classpath. – Tanner Sep 27 '11 at 00:53
  • @Ryan Schipper:there's only jar file but no API-documentation? How could I get that? And is there's no new link to download this API? – Mohammad Faisal Aug 03 '12 at 02:51
  • @RyanSchipper does this create dependencies on the machine that an application (which uses the Communication API) is going to be deployed? – Saher Ahwal Mar 13 '13 at 06:25
  • @Saher an application that uses the Communication API will require an implementation of the Communication API (such as the linked download). And of course, Java Runtime Environment. – Ryan Schipper Apr 05 '13 at 01:25
  • @DmitrySandalov Thanks - I have edited the post to include the java2s link. – Ryan Schipper Apr 02 '14 at 04:43
  • Is that the most recent version? Is it discontinued? It looks like a download site that hoards jar files indiscriminately, that isn't maintained by the authors of javacomm. – Mark Jeronimus Sep 17 '14 at 11:44

    @MarkJeronimus: The latest official version does not support Windows. I have added the official download link and rearranged the links. – Sheepy Dec 05 '14 at 08:28

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
