Efficient, scalable, and flexible Java implementation of the Short Messaging Peer to Peer Protocol (SMPP). This library supports the following SMPP protocol versions:
- 3.3
- 3.4
- most of 5.0
This library's implementation takes advantage of non-blocking (NIO) sockets to support thousands of binds using minimal resources. It can be used to implement either the server, client, or both sides of the SMPP protocol. We use it internally at Twitter for both. Both synchronous or asynchronous request modes can be supported on an SMPP session.
The library has been tested and certified with hundreds of mobile operators and suppliers around the world. It's effective at being flexible with SMPP specifications that aren't truly compliant.
SMPP is notorious for having slight differences depending on the vendor. This library attempts to ensure that the internal PDU parser never breaks regardless of vendor.

Library versions >= 5.0.0 are now published to the Maven Central Repository. Just add the following dependency to your project maven pom.xml:
<dependency>
<groupId>com.cloudhopper</groupId>
<artifactId>ch-smpp</artifactId>
<version>[5.0.0,)</version>
</dependency>
There are numerous examples of how to use various parts of this library:
src/test/java/com/cloudhopper/commons/util/demo
To run some of the samples, there is a Makefile to simplify the syntax required by Maven:
make client
make server
make performance-client
make simulator
make rebind
make parser
make dlr
On Windows, the examples can run with nmake instead of make.
The easiest way to get started is to try out our server and client examples.
Open up two shells. In the first shell, run:
make server
In the second shell, run:
make client
You'll see the client bind to the server and a few different type of requests exchanged back and forth.
