  • Angular-interpolate (Development)

    A light-weight interpolator that replaces delimited keys in a string with values from a properties map. This module was created as a simple alternative for Angular's $interpolate provider. A common use of this tool is for a template interpolation use-case that does not require $parse, $interpolate, or $compile.

  • Jax-rs-auth-seed (Development)

    Why keep reinventing the wheel? The authentication patten has been done over and over again. Get a jump start on implementing your business logic immediately instead of wasting time in making your own.

    This is the back-end component of the angular-auth-seed project. Together, they provide a fully functional platform for authenticated applications based on AngularJS and Java's JAX-RS v2.0 specification. It is a server implementation of the Basic authentication methodology for RESTful applications, written in Java and 100% JAX-RS-compliant. It can be run in servers that implement the JAX-RS 2.0 specification, including Jersey, JBoss RESTEasy, and Restlet. Though any JAX-RS server vendor can be used, I recommend the XRS server, which is a CohesionFirst™ alternative to the JAX-RS 2.0 spec. The XRS server is designed to be ultra lightweight and is configured to run in the Jetty servlet container.

    This is a complete solution, a bug-free and instant "plug-and-play" base to get you started fast and easy. Preconfigured to install the Angular framework, development prerequisites, and testing tools for instant web deployment gratification, this solution can be used to quickly bootstrap your Angular project and dev environment.

  • Angular-auth-seed (Development)

    Why do we keep reinventing the wheel? The authentication patten has been done and done again 1,000,000 times. Instead of spending the first two weeks of development on the authentication requirement, get a jump-start on your business logic immediately.

    Created with the highest standard of development in mind, this project uses best practices and patterns to empower the developer to write code that is clear, cohesive, and easily testable.

    The angular-auth-seed project is a complete solution, intended to be bug-free and an instant "plug-and-play" base to get you started quickly and easily. Preconfigured to install the Angular framework, development prerequisites, and testing tools for instant web deployment gratification, this solution can be used to quickly bootstrap your Angular project and dev environment.

  • Object-prototype-filter (Development)

    A set of supplementary prototype additions to the Object class that provide filtration functions analogous to that of Array.prototype.filter().

  • Lib4j-dbcp (Development)

    Lib4j-dbcp allows a developer to configure a connection pool with a standardized XML Schema, which is used by a consumer class to initiate the connection pool. Lib4j-dbcp uses the JAXB framework to significantly reduce the boilerplate code, thus providing a lean API with support for the all possible connection pool configuration variations.

    Lib4j-dbcp is based on an XML schema used to specify the formal of XML documents accepted by the configuration consumer. The XML schema is designed to use the full power of XML validation to allow a developer to qiuckly determine errors in his draft. Once a dbcp.xml passes the validation checks, it is almost guaranteed to properly initialize the connection pool configured by the file.

  • Lib4j-cli (Development)

    Lib4j-cli allows a developer the full range of variation of the command line arguments pattern, and removes the unnecessary boilerplate code present in other solutions. Lib4j-cli uses the JAXB framework to create a lib4j-cli specification based on a XSD specification, which can be used to create a custom set of CLI options and arguments for any application.

    Lib4j-cli is based on an XML schema that is used to specify the format of XML documents that describe the command line options and arguments accepted by an application. The XML schema is designed to use the full power of XML validation to allow a developer to quickly determine errors in his draft. Once a cli.xml passes the validation checks, it thereafter provides a clear and simple API to access the options and arguments in the code.

  • Relational Database Binding (Development)

    a Java framework for binding to RDBMS data models. Based on the CohesionFirst™ approach, the RDB framework provides a strongly-typed and cohesive approach to connect the DB tier to the business tier.

    jSQL is an extension to DDLx, offering a lightweight object relational mapping (ORM) solution that runs on the JDBC v4.1 API. The jSQL framework provides strongly-typed semantics for the SQL language as well as a cohesive binding to user data models. jSQL uses a SQL schema defined in a DDLx file to create a one-to-one, object-model-to-data-model API that is vendor agnostic.

    In addition to generating Java classes that bind to a DDL, the jSQL framework offers an API for strongly-typed DML semantics. These APIs come in the form of method invocations that resemble a non-cohesive, string-based SQL alternative.

    Strongly-typed DML semantics are powerful because they extend the power of the Java compiler to realize errors in edit-time or compile-time. Alternatively, if non-cohesive, string-based SQL is used, errors are only presented in runtime upon execution by the application to the database. In addition to binding Java classes to the DDL, jSQL provides a strongly typed approach for the construction of SQL DML.

  • SML Schema Binding (Development)

    XSB is a Java framework for binding to an XML schema. Based on the CohesionFirst™ approach, the XSB framework provides a complete solution for cohesive integration of Java applications to XML documents via the XML schema. The framework provides a XSB Java source code generator and a XSB runtime to parse and marshal XML documents to and from Java objects. The XSB framework is a complete implementation and covers the entirety of the XSD 1.1 specification.

    XSB supports all directives of the XSD specification, and generates bindings with highest degree of cohesion possible with the Java language.

  • JAX REST Server (Development)

    XRS is an implementation of the JAX-RS v2.0 specification that runs in a servlet container. This project was inspired with the goal to create a better, simpler, easier to use, reliable, and debugable JAX-RS implementation using the CohesionFirst™ approach.

    XRS was built to implement the JAX-RS v2.0 specification while keeping the internal complexity as low as feasible. Static state is used in but one use-case, so it is never a challenge to debug a request or a response.

    Existing solutions such as Jersey, JBoss RESTEasy, Restlet, Apache CXF, Apache Wink, and others are challenging to work with, because they are buggy, difficult to debug, and are not pure to the JAX-RS specification. Many people experience unnecessary pains using existing JAX-RS implementations. Debugging of JAX-RS servers is especially difficult because of the high internal complexities of the implementations.

    A common pattern that is used in JAX-RS implementations is dynamic method invocation. Dynamic method invocation is powerful, but it comes at a cost: debugability. Dynamic method invocation results in stack-traces that lack information of the specific execution path that led to the exception....

  • JSONx (Development)

    JSONx is a lightweight framework based on an XSD JSONx schema that allows one to create a schema for JSON classes. To its disadvantage, JavaScript is compiler-less and a highly non-cohesive language that results in errors being realized in runtime. As there does not exist a formalized schema specification for JSON, developers often make repeated mistakes when designing JSON messages, encoding JSON objects, and decoding JSON strings. jJB presents a schema model that can be used to bring errors to edit-time and compile-time, greatly reducing the risk of the same errors to appear in run-time.

    JSONx uses a json.jsonx file that conforms to the JSONx Schema to generate Java beans to bind the JSON classes to Java. The generated classes are strongly typed and offer the full benefits of a cohesive interface to JSON objects in Java. The generated classes can be used to parse and marshal JSON messages, confident that all messages conform to the definition in the JSONx....
