Java library for ED2K(eDonkey) networks

Why Java?

Main goal - native application for Android platform. Lighter, faster, more user friendly and convenient than current Mule for Android.

Techniques

• Async network I/O using Java NIO
• Async disk I/O operations emulation via one single thread executor service per session
• Project structure inspired by libed2k

Implemented features

• Packets parsing engine
• Alerts system
• Exception system with one type of exception and error code for each problem
• Search on servers(with all parameter types), search related, search more
• Downloading parts of files
• Downloading compressed parts of files(not recommended as default!)
• Connections policy
• Naive piece picker optimized to download fist and last pieces first for preview feature
• Naive piece manager - online pieces hash calculation and hash verification during downloading

What next

• Stable code, fixing bugs, increase performance
• Advandced piece picker and piece manager
• KAD support

Building Maven/Gradle

Few dependencies in pom.xml - Mockito for unit tests and slf4j logging facade.

1. clone project
2. cd jed2k && mvn package

If you prefer Gradle - use gradle build on second step.

Testing

You can use simple console downloader class org.jed2k.Conn. Before usage you have to set incoming directory as first parameter. Do not use double quotes in commands below - there are for mark parameters. Commands:

• connect to server, default port 4661: connect "server_address_or_ip" [port]
• search on server: search "search_phrase"
• search on server: search "search_phrase" dataSize "limit_in_mb"
• save search results: save
• load search results: restore
• show search results: print
• create transfer: load "hash" "size" "filepath"
• create transfer: load "emule_link"
• create transfer: load "number of search"
• delete transfer: delete "hash"
• exit application: quit

Special case - trial session - fixed sources addresses. Setup -Dsession.trial=true, -Dsession.peers=a.b.c.d:port,....
