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)

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)

Configuring BEA WebLogic 8.1 JDBC Connectivity

This article describes the configuration of various JDBC-related features in the BEA WebLogic 8.1 Server. Although we use Oracle 8.1.7 as our example database management system (DBMS), the general concepts are easily transferable to other relational databases as long as the databases in question provide connectivity through JDBC. Introduction JDBC is a standard Java API that is used directly or indirectly by almost all J2EE applications that require database access. In BEA WebLogic 8.1, configuring JDBC connectivity consists of creating and configuring two main artifacts - JDBC ... (more)

SimpleType and ComplexType in a Schema

This tutorial discusses the simpleType and complexType XML Schema structures and their corresponding representations in an XML document. XML Schema is used as the basis of an XML document structure, and some of the XML technologies, such as JAXB, are based on XML Schema. Overview An XML Schema is an XML-based representation of the structure of an XML document. XML Schema supports data types and namespaces; a DTD does not. In this tutorial, the simpleType and complexType structures used to represent a XML document will be discussed. SimpleType Declaration SimpleTypes are custom da... (more)

How to Create a Directory Service Using the OpenLDAP Directory Server

A directory service is an application(s) that stores, retrieves, and modifies information about network resources such as network users. The actual data is stored in a database; a database service is an abstract layer on top of the database. The Lightweight Directory Access Protocol (LDAP) is a lightweight protocol for accessing directory services. LDAP is based on entries; an entry is a set of attributes identified by a globally unique Distinguished Name (DN). Each of a directory entry's attributes has a type and one or more values. The attributes in a directory entry's distingu... (more)
