too complex in its syntax, and inadequate for all of Javas requirements. Java built on, and improved the ideas of C++, to provide
a programming language that was powerful and simple to use.
Reliability: Java needed to reduce the likelihood of fatal errors from
programmer mistakes. With this in mind, object-oriented programming was introduced. Once data and its manipulation were packaged
together in one place, it increased Java’s robustness.
Secure:
As Java was originally targeting mobile devices that would be exchanging data over networks, it was built to include a high level of
security. Java is probably the most secure programming language to date.
Platform Independent: Programs needed to work regardless of the
machine they were being executed on. Java was written to be a portable language that doesnt care about the operating system or the
hardware of the computer.

reports. All in all, Jasper Reports combines good features, maturity, community
participation, and, best of all, its free. This article kicks off Java Worlds new Open Source Profile column dedicated to Java-based open source tools and
components. Look for upcoming articles spotlighting the Echo Web application framework and ObJectRelationalBridge, an objectrelational mapping tool. Feel
free to send me your suggestions for future articles.
