Latest version: 3.0.13
Added 2005-06-24

The Hessian binary web service protocol makes web services usable without requiring a large framework, and without learning yet another alphabet soup of protocols. Because it is a binary protocol, it is well-suited to sending binary data without any need to extend the protocol with attachments.

Java Excel API

Home Page

Categories: Interoperability, Miscellaneous

Latest version: 2.6.2
Added 2005-08-26Updated 2006-06-07

jexcelapi allows Java developers to read Excel spreadsheets and generate Excel spreadsheets dynamically. In addition, it contains a mechanism which allows Java applications to read a spreadsheet, modify some cells and write the modified spreadsheet.

Thanks to jexcelapi non Windows operating systems can run pure Java applications which process and deliver Excel spreadsheets. Because it is Java, this API may be invoked from within a servlet, thus giving access to Excel functionality over internet and intranet web applications.

Features include:
- Reads data from Excel 95, 97, 2000 workbooks
- Reads and writes formulas (Excel 97 and later only)
- Generates spreadsheets in Excel 97 format
- Supports font, number and date formatting
- Supports shading and colouring of cells
- Modifies existing worksheets

Categories: Interoperability, Reporting

Author: Apache Jakarta

The POI project consists of APIs for manipulating various file formats based upon Microsoft's OLE 2 Compound Document format using pure Java. In short, you can read and write MS Excel files using Java. Soon, you'll be able to read and write Word files using Java. POI is a Java Excel solution as well as a Java Word solution. However, it is a complete API for porting other OLE 2 Compound Document formats and others to participate.

OLE 2 Compound Document Format based files include most Microsoft Office files such as XLS and DOC as well as MFC serialization API based file formats.

JuggerNET

Categories: Interoperability

Author: Codemesh

Latest version: 3.2.11
Added 2004-02-19Updated 2007-09-18

Tool that takes compiled Java classes as input and generates in-process C# bindings for them.
Under the hood, the JuggerNET runtime uses P/Invoke and JNI to execute the original Java in the CLR process.

Among other things, JuggerNET can be used to:
- publish .NET versions of Java APIs
- publish COM bindings for Java APIs
- integrate .NET clients into JMS or EJB applications
JuggerNet consists of:
- a code generator, GUI and command line: it takes Java bytecode as input and generates platform- and compiler-portable C# source files, batch build files, and project files.
- a runtime library: comes in two flavors, strongly named and not strongly named, and provides an abstraction layer around the generic aspects of Java and .NET integration. The runtime library represents our expert knowledge of the runtime aspects of Java/.NET interoperability.
- a Shared JVM server: provides you with an alternate deployment option that does not require the presence of a Java Runtime Environment on the host that is running your .NET code.

SWIG

Home Page

Categories: Interoperability

Latest version: 1.3.33
Added 2005-02-10

Development tool that connects programs written in C and C++ with a variety of high-level programming languages.
SWIG (Simplified Wrapper and Interface Generator) is used with different types of languages including common scripting languages such as Perl, Python, Tcl/Tk and Ruby. The list of supported languages also includes non-scripting languages such as C#, Common Lisp (Allegro CL), Java, Modula-3 and OCAML. Also several interpreted and compiled Scheme implementations (Chicken, Guile, MzScheme) are supported. SWIG is most commonly used to create high-level interpreted or compiled programming environments, user interfaces, and as a tool for testing and prototyping C/C++ software. SWIG can also export its parse tree in the form of XML and Lisp s-expressions.

The C# module offers an automated way of accessing existing C/C++ code from .NET languages. The wrapper code implementation uses the Platform Invoke (PInvoke) interface to access natively compiled C/C++ code. Swig C# works equally well on non-Microsoft operating systems such as Linux, Solaris and Apple Mac using Mono and Portable.NET.
The Java extension to SWIG offers a way of accessing existing C/C++ code from Java. SWIG writes the Java Native Interface (JNI) code for you. It is different to using the 'javah' tool as SWIG will wrap existing C/C++ code, whereas javah takes 'native' Java function declarations and creates C/C++ function prototypes. SWIG wraps C/C++ code using Java proxy classes and is useful if you want to have access to large amounts of C/C++ code from Java.

Author: JNBridge

Latest version: 2.2
Added 2003-05-20Updated 2004-12-10

Java/.NET interoperability tool that enables two-way interoperability between Java and .NET.
With JNBridgePro, Java can access .NET objects and classes, and .NET can access Java classes and objects.
JNBridgePro creates the interoperability bridge by generating a set of proxies that expose the classes' APIs and manages the communications between the .NET and Java classes. You can explore Java or .NET classes with the proxy generator GUI and determine which classes should have their functionality exposed. JNBridgePro automatically generates the proxies, and will optionally find and expose all the necessary supporting classes.

Excelsior JET

Categories: Compilation - Bytecode manipulation, Interoperability

Author: Excelsior

Latest version: 5.0
Added 2005-02-06Updated 2007-09-17

Java Virtual Machine enhanced with Ahead-Of-Time (AOT) compilation.

The AOT compiler transforms classes and jars into binary executables that run directly on hardware for Windows and Linux on the Intel x86 platform. These executables work faster than the original class files executed within a conventional JVM. In addition, your applications become more secure against tampering and code theft.
VM components responsible for Java memory management, threading, synchronization, security, etc., are placed into a DLL that you redistribute along with the precompiled executables. Among those runtime components is a JIT compiler that takes care of classes that could not be precompiled, thus enabling Excelsior JET to support the entire Java 2 Platform, Standard Edition 5.0 API, including dynamic class loading.
Your applications can use JNI and Invocation API to interoperate with C, C++ and Delphi, or use COM to interoperate with C++, VB6, VBA (and probably any other language that supports the COM interface).
