There are several utilities developed at the Xerial projects:

Xerial (http://www.xerial.org ) is an open-source XML Database Management System (DBMS) implemented in C++ and Java.

• Project Names : Xerial (C++), XerialJ (Java)
• XerialJ includes XerialCore , XerialStorage packages.
• For now, Xerial C++ is not an open-source project until the problem #108 is resolved.

SQLite JDBC is a Java Database Connection (JDBC) Driver for SQLite.

• SQLite is a ready-to-use relational-database engine that can be run on a single file (or multiple files), which does not require any installation process.

BeanUtil

BeanUtil is a Binding Toolkit for Java Object and Tree-Structured Data (XML, JSON, Map, ANTLR Parse Tree, etc.).

• Contained in XerialCore package.
• I use this BeanUtil to read XML/JSON/ANTLR Parse tree data into my Java programs. With this BeanUtil library, it becomes fun to handle tree-structured data, since there is no need to write complex SAX/DOM style programs.
• BeanUtil library is also utilized in UTGB (University of Tokyo Genome Browser) Framework, which is a web-based database development framework that enables the Biology researchers, who are usually not familiar with programming, to launch a new web-site for instantly serving Biological databases.

• Pull-Style JSON Data Reader for Java
• contained in the XerialCore package
• API: http://www.xerial.org/maven/repository/site/xerial-project/apidocs/org/xerial/json/JSONPullParser.html

Command-Line Argument Parser (OptionParser )

• for Java 1.5 or higher
• contained in the XerialCore package
• API: http://www.xerial.org/maven/repository/site/xerial-project/apidocs/org/xerial/util/cui/OptionParser.html

UTGB (The University of Tokyo Genome Browser Framework)

• UTGB is a bundle of Java libraries for developing web-based database servers. This includes portable Tomcat server, SQLite database engine (or connection to other DBMSs through JDBC), AJAX-style graphical user interface for data browsing, which is implemented using Google Web Toolkit (GWT).

Portable Tomcat Web Server

• With this program, you can start up the Tomcat Web Application Server from your Java programs. No daemon process.
• http://www.xerial.org/maven/repository/site/xerial-project/apidocs/index.html
• which is integrated into UTGB framework.

• http://www.xerial.org/maven/repository/artifact/org/xerial/maven/maven-antlr-plugin/
• A maven plugin for generating Java lexer/parser codes from ANTLR grammar files in your source folder.

• Features: Student Data Management, Report Submission through the Web, Edit Scores, etc.
• http://www.xerial.org/svn/project/ruby/trunk/lecture
• written using Ruby on Rails
