with both Smitch charts and SWR/PWR curves. Does drag-and-drop schematic entry
with direct entry of component values as well as "drag tuning". Can import
load parameters directly from the following:
- EZNEC (and EZNEC GAM files)
- miniVNA and miniVNApro
- AIM4170
- CocoaNEC
- Rig Expert ".aaplot" files
- Touchstone S1P ".s1p" files (shunt and series)
Pebble is a lightweight, open source, Java EE blogging tool. It's small, fast

your web browser, making Pebble ideal for anybody who is constantly on the move
or doesn't have direct access to their host.
BYACC/Java is an extension of the Berkeley v 1.8 YACC-compatible parser
generator. Standard YACC takes a YACC source file, and generates one or
more C files from it, which if compiled properly, will produce a LALR-
grammar parser. this extension support a -J option to generate Java source
code.
The Java Service Wrapper is an application which has evolved out of a desire
to solve a number of problems common to many Java applications:
- Run as a Windows Service or Unix Daemon.
- Application Reliability.
- Standard, Out of the Box Scripting.
- On Demand Restarts.
- Flexible Configuration.
- Ease Application Installations.
- Logging.

HyperSQL
HSQLDB is the leading SQL relational database engine written in Java. It has a
JDBC driver and supports a rich subset of ANSI-92 SQL (BNF tree format) plus
SQL 99 and 2003 enhancements. It offers a small (less than 100k in one version
for applets), fast database engine which offers both in-memory and disk-based
tables and supports embedded and server modes. Additionally, it includes tools
such as a minimal web server, in-memory query and management tools (can be run
as applets) and a number of demonstration examples.
JSAP: the Java-based Simple Argument Parser
JSAP parses your command line and instantiates objects of types you specify
based upon that command line. If you configure JSAP to expect an Integer on the
command line, and the user does not provide a String that can be converted to
an Integer, JSAP will alert your program to the fact that there was a problem
with the command line. If JSAP indicates that your command line was
successfully parsed, you are guaranteed an Integer when you request that
parameter's value from your program. There's a pretty big (and growing) list of
return types supported by JSAP.
The Digester package lets you configure an XML -> Java object mapping module,
which triggers certain actions called rules whenever a particular pattern of
nested XML elements is recognized. A rich set of predefined rules is available
for your use, or you can also create your own. Advanced features of Digester
include:
- Ability to plug in your own pattern matching engine, if the standard one is
not sufficient for your requirements.
- Optional namespace-aware processing, so that you can define rules that are
relevant only to a particular XML namespace.
- Encapsulation of Rules into RuleSets that can be easily and conveniently
reused in more than one application that requires the same type of
processing
