    Volley

    Volley

    HTTP library that makes networking for Android apps

    Volley is an Android networking library that streamlines making asynchronous HTTP requests, caching responses, and managing image loading with minimal code. It provides request queues, thread pools, and lifecycle-aware cancellation so network work integrates cleanly with activities and fragments. Out of the box it supports JSON, string, and image requests, plus an extensible Request/Response model for custom payloads. Volley emphasizes responsiveness: transparent caching and de-duplication of in-flight requests help reduce latency and bandwidth usage. Error handling, retries with backoff, and request prioritization are first-class, making it easier to handle flaky mobile networks. While Android has other HTTP stacks, Volley’s value is in opinionated, high-level primitives that fit common app patterns without pulling in heavy dependencies.

    UI components for apache wicket

    The „wicket components“ project is a component library for the apache wicket web-framework. Referring to classic component libraries for desktop applications ( like Microsoft Foundation Classes, QT Library or wxWindows) the wicket components provide graphical user interface components for wicket web-applications. Based upon this library it'll be easy to create complex user interfaces for data processing applications and it is a perfect start to migrate old desktop applications to modern web-applications. The project is getting bigger and bigger. Your help is greatly appreciated.

    WSCreator

    Java library for automated Soap & Rest web Services Creation

    An awesome new way of adding SOAP and REST web services to any Spring IOC based Java project in minimum time. This library takes out all the pain part of implementing Soap & Rest Web Services specific code from developer's plate and does it in a very smart way. All you need to do is add dependency of this library to your project, add some annotations to your interfaces, add a servlet entry into your web.xml. & you are all set to go. Library uses Apache CXF to create SOAP based web services & for REST it uses Spring MVC. All the dynamic code is written at boot time. This library reduces precious development time & developers can actually focus on writing business code & other project specific stuff. See implementation details: http://sourceforge.net/projects/ws-creator/files/ Demo Application: http://sourceforge.net/p/wscreatordemo Central Repository link: http://search.maven.org/#search%7Cga%7C1%7Cwscreator

    Wheefun Computer Prototyping Kit

    A Toolkit for Designing Computers

    This package is designed for people who are a) interested in writing emulators or b) integrating this level of detain into their applications (e.g., a video game). The ability to do this is useful because a) it allows for tinkering far before physical implementation of the design is. In addition to a strong core, WFCPK will also include modules emulating various processors (e.g., the MOS 6502 and the Zilog Z80) as well as the Video-Audio Interface (a custom VGA-compatible display and audio controller). The VAI is designed to fit within an FPGA to be integrated into real designs. This library is licensed under the GPLv3 but also includes the classpath exception so that proprietary software can be linked against it required.

    WrapImaJ

    Multi-platform API for Image Processing systems in Life Sciences

    WrapImaJ purposes to be a multi-platform wrapper for different Image Processing systems for: - using the Java programming language. The purpose of WrapImaJ is not to combine an exhaustive collection of all functionalities of different imaging system, but to offer a simple, concise Application Programming Interface (API) - allowing to develop imaging software, the source code of which is independent from the underlying imaging system on which it relies. In it's current form, it only wraps basic functionalities of ImageJ. The developers of WrapImaJ intend the library to support compatibilty with the main imaging systems available in the Java language and broadly used in the field of life sciences.

    XLSX parser for Java in 150 LOC

    An extremely minimal parser for XLSX (Excel) files

    I was unable to find a minimal XLSX (Excel) parser. The closest free option would be apache POI with about 8+ megabyte of JARs and features I don't need. The input is an XLSX file and the output is a Map<String,String[][]> with key of 'sheet name' and a String[][] of cell data. Dates are reformatted to dd/MM/yyyy (configurable in the code). The output of String[][] is to keep the interface compatible with CSV (eg. OpenCSV).

    XML-CF-lib

    XML-CF-lib

    TeleScope-CF XML Content Filtering Library

    Current TeleScope-CF Java library implementation employs XML parsing and specific pattern-matching that provides standard logical operator constructs to construct the query over the values of XML elements and attributes applied to the XML message on the fly as it is provided in the form of a String object. The code base has been adopted from TeleScope CQ XML stream broker code base written in C. C code has been re-factored into Java with minor modifications. This general-purpose library could be used by any Java applications that are involved in the XML message content filtering. Example application scenarios could be intrusion detection, selective rule engines, targeted database insertions during the ETL process and various business logic scenarios. The library could also be used in XML routers and various web services for XML content filtering where XML is a common message passing format.
