Many algorithms are expressed most concisely as tail-recursive methods. Compilers can automatically transform such methods into loops and thereby improve program performance, but this transformation is not required by the Java language specification, so not all JVMs will perform it. This means that tail-recursive methods in the Java language can result in unexpectedly large memory usage. This article demonstrates that dynamic compilation maintains the language's semantics while static compilation often doesn't. Learn why this matters and get a bit of code to help you determine whether your just-in-time (JIT) compiler can transform tail recursion on code while preserving semantics.

A brief note about some possible causes of runtime problems which may prevent Java applets from working correctly.

The corporate firewall is a double-edged sword. It helps prevent unauthorized access to the corporate Web services, but can disable access for legitimate clients. Due to the number of safety measures taken by system administrators, HTTP has become the universal entry mechanism to the corporate network. Where technologies such as CORBA and DCOM have failed because of the firewall, technologies such as SOAP have been developed to provide safe and reliable access through firewall protection. This article explores an alternative to SOAP, the use of Java objects over HTTP. In addition, it uses J2EE servlet technology as server-side middleware to the business data.

Facilitate the testing of management applications for heterogeneous storage devices using a Storage Management Initiative Specification-based simulation tool. This tool allows you to simulate storage devices from a console, enabling testing of storage device management architecture. This testing saves time and expense and eliminates the cost of purchasing actual storage devices.

Employ a tool that uses an analysis engine to resolve problems related to Java Database Connectivity connection pools and find connection leaks. JDBC is used by applications written in Java to define how a client accesses database resources. Connection pooling improves the response time of an application that requires connections, especially Web-based applications.
