Running JavaTM technology applications on the SolarisTM Operating Environment (Solaris OE) ensures achieving the highest service levels at the lowest service level cost. The latest release of JavaTM 2 Platform, Standard Edition (J2SETM) platform has feature enhancements that, in combination with the SolarisTM Operating Environment (Solaris OE) Software, deliver the optimum Java technology platform for deploying mission-critical applications and services.

Solaris OE users know that 64-bit support within the operating environment is not new, but with J2SE 1.4 platform, users benefit from full 64-bit support in the Java HotSpotTM virtual machine (JVMTM). This new feature, combined with the Java HotSpot Server VM code optimizer, has significantly improved Java technology servlet performance over previous versions.

Additional benefits of the 64-bit support lie primarily in scalability and performance, including:

• Ability to handle more concurrent network socket connections, enabling real-time provisioning of socket connections

• Access to larger memory spaces, thereby maximizing use of massive memory capabilities of the latest Sun servers, for example, the Sun FireTM 15K Server with several hundred GByte of memory. The previous version, J2SE 1.3.1 platform, supported 4 GB memory

• Record breaking SPECjbb2000 benchmarks on the 72 CPU Sun Fire 15K Server with results showing more than 1.5 times greater performance over J2SE 1.3.1 platform on Solaris OE

More New Features in J2SE 1.4 Platform for the Solaris OE

Java technology is designed for development and deployment on all industry-leading platforms, but when used with the Solaris OE, the user benefits from synergy between J2SE platform and Solaris OE platform features. In the latest release, users can expect the following significant improvements over previous J2SE platform releases:

• IPv6 Support: J2SE 1.4 platform contains developer APIs that work well with both IPv4 and IPv6 protocols in the Solaris 8 OE.

• Improved Enterprise JavaBeansTM (EJBTM), JavaTM Servlet, and instant messaging performance: EJB components, which are a critical component of most JavaTM 2 Platform, Enterprise Edition (J2EETM) applications, experience at least 34 percent performance improvement over the J2SE 1.3.1 platform. Furthermore, performance of "Instant Messaging"-type applications has shown to improve 73 percent over J2SE 1.3.1 platform.

• See table online for Security Enhancements: J2SE 1.4 platform includes a list of security enhancements.

These features, combined with Solaris OE security features such as Role Based Access Control (RBAC), integrated host-based firewall, GSSAPI and smart card support, all make for a Java technology deployment that doesn't compromise security for the benefit of performance.
