The need for a server-side JVM is evident. The increase in the number of Java applications on the servers, and the exponential rise in the number of clients accessing these Java applications, brings forth the shortcomings in the traditional Java VMs, which are more tuned towards client-side processing. The first question that comes to mind when talking about JRockit is the comparison between the JRockit JVM and the Sun JVM. Although this article does not focus on this distinction, I will present a brief history of JRockit and then discuss the management and monitoring features introduced in it. A few of the major issues with these JVMs are their ability to handle threads, the time taken for garbage collection, and the management of I/O operations.

Creating Web Services

You can create a Java Page Flow application in BEA WebLogic Workshop that utilizes a Service control generated from a Web service. This article uses the example of an external Web service listed on the XMethods.net site. We will import the WSDL for the Web service into BEA WebLogic Workshop and see the custom Service control that is generated. We will then consume this control within a simple Page Flow application. We can also create a sample JWS file that allows you to quickly test the control. Getting the WSDL File from XMethods.net Visit the XMethods.net site. It lists a number ... (more)
