IDE

If the results of the just-completed Java.net poll are at all representative of the broader Java/JVM community (our polls are not scientific, of course), the indication is that Java/JVM developers like staying pretty much up to date when it comes to their IDE. A total of 159 votes were cast in the poll, which ran for two weeks. The exact question and results were: How frequently do you...

GUI

In the previous post in this mini-series regarding the work I do on NASA Ground Systems, I showed some screenshots demonstrating data visualization.  The basic tech stack involves combining the NetBeans Platform with custom JavaFX views. This pattern provides some very useful "At-a-Glance" (AoG) displays associated with daily data product generation. AoG is typically appropriate, especially...

Visual Library is a library in NetBeans, which you can use in standalone Java apps, for doing beautiful, complex, animated layouts. JUNG is a library for exploring graphs of connected data. What if we put those two things together? That's what I did. The result is on GitHub. Video demo and more info over on my timboudreau.com blog.

JSR

In this blog entry I outline the steps necessary to deploy JAX-RS (JSR 311) RESTful web services to the Oracle Cloud. We'll be using Jersey, which is the reference implementation for JAX-RS, and JDeveloper, which is my primary Java IDE. Step 1. Create a Jersey Library in JDeveloper Download the latest version of jersey-bundle.jar, which at the time of this writing is version 1.17.1. Start...

Programming

Earlier versions of VisualLangLab required the user to specify an alphanumeric name for all tokens. This made it difficult to understand rules using tokens without intuitive names. A good example is the rule infixOp from a Java grammar in Figure-1 below. Figure-1. Rule with non-intuitive token names While PLUS and MINUS have good mnemonic value, many users will not understand TILDE and BANG. And...

Concentrating on Task in Hand (similar to Mylyn) in NetBeans IDE Often we work on fixing a bug or developing an enhancement for an open source project maintained over a period of many years and having hundreds of source code files.  usually we need a handful of 5 to 10 source files to fix the bug or to add new enhancement.  The project explorer provided by IDE's like NetBeans IDE show...

With the release of version 6.01, VisualLangLab can support all -- present & future -- JVM languages.  VisualLangLab's approach of composing parsers at runtime by using combinator functions instead of generating code (as other parser generators do) enables these parsers to be embedded into a host program in any JVM language. Eschewing code generation also eliminates all host-language...

A preview of the pure Java version of VisualLangLab is available here. The GUI, and other characteristics, remain virtually unchanged (see documentation), but the download is very much smaller as it does not bundle the entire Scala API. The preview does not yet support packrat parsing, and an API for application programs is not yet available. All grammar development and testing features are...
