Practical Teaching of JAVA-J2ME mobile development
Java 2 Micro Edition is a part of Java 2 and is also known as j2se and J2EE. It is a highly optimized Java operating environment and is applied to a large number of consumer electronic devices, such as cell phones, visual phones, digital set-top boxes, and car-oriented systems, it is also widely used by mobile communication devices, such as mobile phones, two-way pagers, smart cards, perso

XTages
This library provides a simplified process of parsing and transforming XML documents using XSLT. It can be used to apply an XSLT transformation to an XML document, add or delete XML nodes, evaluate Xpath expressions, and define template rules. Use this library when you need advanced XML/XSLT processing.
Regexp
This library allows you to use regular expressions compatible with Perl5 in JSP applications. This library supports Pe
