Open Source Java Libraries

A Java library for executing, parsing and persisting NMap output.

Java library to send and receive data via Serial COM-Ports. This library is intended to provide an easy way to access the serial-port. Only a few lines of code are needed to Read or Write data via serial port. All Properties and Methods are inspired by the "SerialPort"-Class of the .NET Framework (System.IO.Ports.SerialPort) The benefit of this project is, that it needs only a few lines of code to implement, and a reduced CPU load. Static Methods are available to send/receive String values. For the complete JavaDoc: http://easymodbustcp.net/jserial/javadoc/index.html The library works with Windows 64Bit and Linux 64Bit and Linux 32 Bit ARM (Raspberry Pi)

jWlanScan is a free (LGPL) wireless network(WiFi) scan library for the Java platform. It uses JNI technology, supports WinXP,Win2003, can get access point information of AP NAME,RSSI,BSSID,SPEED,CHANNEL and more.Use this lib,developed a WlanScan tool.

A library for sending AWS Signature Version 4 signed requests over HTTP to Amazon Neptune. This package provides signers that can be used with various implementations of HttpRequests. AWS Identity and Access Management (IAM) is an AWS service that helps an administrator securely control access to AWS resources. IAM administrators control who can be authenticated (signed in) and authorized (have permissions) to use Neptune resources. IAM is an AWS service that you can use with no additional charge. You can use AWS Identity and Access Management (IAM) to authenticate to your Neptune DB instance or DB cluster. When IAM database authentication is enabled, each request must be signed using AWS Signature Version 4. AWS Signature Version 4 adds authentication information to AWS requests. For security, all requests to Neptune DB clusters with IAM authentication enabled must be signed with an access key. This key consists of an access key ID and secret access key.

Commons-SSH is a thin bridge between different Java SSH implementations libraries. It doesn't contain any crypto-related code and created to be used by projects who doesn't want to care about export control regulations (let client to decide)

Fast Android Networking Library is a powerful library for doing any type of networking in Android applications which is made on top of OkHttp Networking Layer. Fast Android Networking Library takes care of each and everything. So you don't have to do anything, just make a request and listen for the response. The recent removal of HttpClient in Android Marshmallow(Android M) made other networking libraries obsolete. No other single library does and everything like making requests, downloading any type of file, uploading file, loading images from the network in ImageView, etc. There are some libraries but they are outdated. No other library provides a simple interface for doing all types of things in networking like setting priority, canceling, etc. As it uses Okio , No more GC overhead in android applications. Okio is made to handle GC overhead while allocating memory. Okio does some clever things to save CPU and memory.

This Library provides a java API for firewall logs, connection tracking and rules management.

PROJECT HAS MOVED HERE: https://github.com/Elektordi/x-way-uni-te X-Way and UNI-TE (also used in Unitelway) are communication protocols for old Schneider Electrics PLCs (Programmable Logic Controllers), formerly "Modicon Télémécanique". The aim of this open-source project is to create a Java library to send and receive such data, because there is actually no open-source project at all in this field. Keep in mind that those protocols are old and not maintained anymore by any company, but still used in many old PLCs installations.

Basic Java infrastructure for asynchronous socket service clients and servers. Inspired by asyncore Python module. See doc/TestServer.java for a server implementation example. See doc/TestClient.java for client implementation examples.

JavaRTMP is a Java library for interacting with Adobe Flash Player and Adobe Air applications via the RTMP protocol

Ribbon is a Inter Process Communication (remote procedure calls) library with built in software load balancers. The primary usage model involves REST calls with various serialization scheme support. Ribbon comprises of multiple components some of which are used in production internally and some of which were replaced by non-OSS solutions over time. This is because Netflix started moving into a more componentized architecture for RPC with a focus on single-responsibility modules. So each Ribbon component gets a different level of attention at this moment. APIs that integrate load balancing, fault tolerance, caching/batching on top of other ribbon modules and Hystrix. Load balancer APIs that can be used independently or with other modules. APIs using Eureka client to provide dynamic server list for cloud.

SimpleNet is a small Java network library that should aid in writing fast and lightweight network protocols without having to fuzzle around too much with protocol decisions. It mainly aides in message dispatching and abstraction.

Stagemonitor is a Java monitoring agent that tightly integrates with time series databases like Elasticsearch, Graphite and InfluxDB to analyze graphed metrics and Kibana to analyze requests and call stacks. It includes preconfigured Grafana and Kibana dashboards that can be customized.

Java-based Open Source WAF (Web Application Firewall) to include inside a web application in order to protect it against attacks like Cross-Site Request Forgery (CSRF), Parameter Manipulation and more.

Powerfull DNS Server (fully customizable and *scriptable*) and pure Java DNS Protocol implementation

jBingAPI is a java library to query the microsoft search engine bing (http://www.bing.com/) using their public api. jBingAPI just makes it a lot easier to communicate with this api.

jLightning is a Java NIO networking library. This project has been moved into the jeuron project. Please refer to www.jeuron.org for more detail.

A Java implementation of a NAT-PMP client. At the project's inception, there was not a well-known NAT-PMP client library for Java. This project intends to fill the gap.

Json-rpc 2.0 implementation in Java. If you like it, please add review.

Framework for manipulating Connections: The API mean purpose is provide a unified API through Adaptersto easily incorporate a third-party library into existing application. Also provide an efficient NIO based implementation supporting UDP and TLS

proJMS is a library for Processing that allows the easy usage of JMS. It allows to publish and consume JMS messages and to create peer to peer communication between processing applications in a network. Refer to the wiki for installation and usage instructions.

snmpAdaptor4j is an adaptor for Java Management eXtensions (JMX) providing a simple access to MBeans via the SNMP protocol. Thus, this adapter you allow to connect most monitoring tools (like Nagios and Cacti) to your Java applications. For each MBean, an XML mapping file allows to establish the relationships between attributes and the MIB of the SNMP adapter. No additional code is necessary to integrate the MBeans in the SNMP protocol. This adapter can work in a multi-applications environment (such as application servers).

The Zabbix trap (zabtrap) client library allows you to send traps to a zabbix trap item configured on a zabbix server from your Java applications. For a full JMX Zabbix bridge (zabbix agent), check out http://www.kjkoster.org/zapcat/
