Clustered Remoting for Spring Framework (Cluster4Spring) represents an alternative implementation of the remoting subsystem of Spring framework and provides possibilities to build more stable and fault tolerant systems with dynamic discovering of remote services. Cluster4Spring uses Apache 2.0 license that allows using it both in commercial and non-commercial products.

• Support of one-to-one scheme of remoting (similar to one currently supported by Spring);

• Support of one-to-many scheme of remoting, which assumes that one client selects remote service for invocation from one of predefined locations;

• Support of one-to-many scheme of remoting with dynamic discovering of remote services;

• Several built-in policies for selecting remote service for invocation are included (they are applied if service is available in several locations);
• Built-in functionality for handling remoting exceptions of method invocations that provides ability to re-invoke remote service using different service location automatically;
• Steep learning curve since ideological implementation of Cluster4Spring bears a close resemblance to the implementation of remoting in Spring;
• Non-intrusive for existing applications – it is simply enough to change appropriate remoting-related Spring configuration files to start using Cluster4Spring;
• Provides a convenient way to add custom interceptors both on client and server side;
• Flexible and modular architecture which is ready for further extensions and customizations;
• Library is stable and ready to use;

Another feature, which is currently missing in remoting subsystem offered by Spring framework, is lack of the ability to dynamically discover remote services.

The main purpose of Cluster4Spring is to extend remoting system of Spring framework and overcome limitations mentioned above.

The Cluster4Spring library was developed in SoftAMIS, a Ukraine based software development company specialized on Java and Web development outsourcing services. To find more about SoftAMIS, our services, skills and experience, please visit our site –

Batik is a Java-based toolkit for applications that want to use images in the Scalable Vector Graphics (SVG) format for various purposes, such as viewing, generation, or manipulation.

The Apache Software Foundation or ASF is a non-profit that hosts a number of open source projects. Apache projects are licensed under the namesake Apache License, and development is managed by small groups of active project contributors. Apache gets its name from its founding project, the Apache WebServer that is also its most popular project.

Apache projects have a lifecycle in which new projects are added to a project incubator, when development goals are met and the project takes off it may be added to the roster of other active Apache projects.

The organization itself serves as a legal overhead for Apache contributors, dealing with licensing and trademark issues, as well as providing services and holding events for the general apache community.

EasyStub is a framework for making stubs. When you find most of time you are using a mock framework to create an object that always returns the same value, and you did not care about the interactions, what you need is actually a stub.

Examples:

• MyInterface stub = createStub(MyInterface.class);

• make(stub.hello()).returning(‘hello’);

• make(stub.hello()).throwing(expectedException);

• stub.nothing();
• willThrow(expectedException);

Spline.NET is a simple and flexible .NET object – relational mapping system built on top of ADO.NET. It is simpler than Ibatis.NET or NHibernate and allows full access to the ADO.NET APIs, rather than replacing them. Spline uses attributes to minimize the amount of boilerplate code needed to populate or save a domain object from a data source.

Spline.NET also leverages attributes to obtain all configuration information (such as connection strings or other externalized settings). This feature in and of itself is extremely useful in and outside the scope of Spline.NET. It can be thought of as a very lightweight “inversion of control” feature, where properties can loaded from an external settings file without ever having to manually set the value of each property.

Spline also includes a small set of utility libraries to do simple tasks such as password hashing/generation and stream handling.

JDOM is a java library for XML manipulation. This includes access, manipulation and output.

The most recent version is Version 1.0, which is available in both binary and source from from the project site.
