A J2EE application deployed in the WebLogic server may be debugged in the Eclipse IDE with the remote debugger provided by Eclipse. Without a debugger the error message has to be obtained from the application server error log to debug the application. With the remote debugger provided by Eclipse, exception breakpoints may be added to the application file to debug. When an application is run in WebLogic and the application generates an error, the application gets suspended and the Eclipse IDE Debug perspective displays the error. In this tutorial we will debug a WebLogic Application Server application in Eclipse. To debug an application deployed in the WebLogic Server from Eclipse, start the WebLogic Server in debug mode and configure a remote debugging configuration in Eclipse. Next, connect the Eclipse remote debugger to the WebLogic Server and debug applications r... (more)

XML Schema Binding with XMLBeans

XMLBeans is an open source XML-Java binding tool used to generate Java classes and interfaces from an XML Schema. The generated Java classes may be used to parse or generate an XML document that conforms to the Schema. Some of the advantages of XMLBeans over JAXB are the ability to parse an XML document and support for all of the XML Schema constructs; the JAXB-generated classes do not have a parse method to parse an XML document, and JAXB does not support all of the Schema constructs. XMLBeans provides the XMLObject, XMLCursor, and SchemaType APIs to parse or construct an XML d... (more)

Migrating a JBoss EJB Application to WebLogic

The JBoss open source application server is commonly used in the development phase of a J2EE project. In the production phase the commercial BEA WebLogic server is preferred because of its enhanced set of features. Without modifications, an application developed in JBoss does not deploy in WebLogic server. The deployment descriptors for the WebLogic server are different from the JBoss deployment descriptors. An application may be migrated to WebLogic by converting the vendor-specific deployment descriptors to WebLogic. In this tutorial an EJB application developed in JBoss will ... (more)

Configuring the WebLogic-Eclipse Plug-in

The WebLogic-Eclipse plug-in is designed to run the WebLogic Server from the Eclipse IDE. With the WebLogic-Eclipse plug-in, the WebLogic Server gets started and stopped from Eclipse. An application deployed in the WebLogic Server can be debugged from Eclipse with the plug-in. By installing the WebLogic plug-in in Eclipse the WebLogic Server can be configured and administered from the Eclipse IDE by setting the server classpath and JVM options in Eclipse. Overview A J2EE developer is commonly required to administer the WebLogic Server and debug applications deployed in the WebLo... (more)

WebLogic Tutorial: "Integrating Apache Poi in WebLogic Server"

The Apache Jakarta POI project provides components for the access and generation of Excel documents. The POI HSSF API is used to generate Excel Workbooks and to add Excel spreadsheets to a workbook. An Excel spreadsheet consists of rows and cells. The layout and fonts of a spreadsheet are also set with the POI HSSF API. A database table is often required to be presented in an Excel spreadsheet. Also, a developer's requirement could be to store an Excel spreadsheet in a database table. The Apache POI HSSF project is an API to create an Excel spreadsheet. The data in the Excel spr... (more)
