The Enterprise Deployment Wizard features a context-sensitive online Help system. For usage information, see the online Help. XDoclet integration JRun provides integration with XDoclet, a popular open-source Java utility that greatly simplifies the development of J2EE modules (such as EJBs, servlets, and custom tags) by letting you maintain your component metadata using Javadoc-style tags in a single source file. For example, to create an EJB, you traditionally have to maintain four different files: the home interface, the remote or local interface, the implementation class, and the deployment descriptor. Using XDoclet, you only maintain a single source file (the implementation class) that you annotate with special Javadoc tags, that indicate how the auxiliary files should be built. JRun senses modifications to the source file and automatically builds the auxiliary files (such as interfaces and deployment descriptors). For more information, see JRun Programmer's Guide. Pointbase database server JRun includes a restricted version of the PointBase Server Database Management Software (DBMS). This is an all-Java database used with the JRun sample applications. You can use this database server for your evaluation and development work. For more information on the PointBase database, see the PointBase documentation, located in jrun_root/pointbase/docs. (jrun_root is the directory into which you installed JRun.) JDBC Drivers JRun embeds type 4 JDBC database drivers that provide connectivity to all major databases.

The Enterprise Deployment Wizard features a context-sensitive online Help system. For

usage information, see the online Help.

XDoclet integration

JRun provides integration with XDoclet, a popular open-source Java utility that greatly

simplifies the development of J2EE modules (such as EJBs, servlets, and custom tags) by

letting you maintain your component metadata using Javadoc-style tags in a single source

file.

For example, to create an EJB, you traditionally have to maintain four different files: the

home interface, the remote or local interface, the implementation class, and the

deployment descriptor. Using XDoclet, you only maintain a single source file (the

implementation class) that you annotate with special Javadoc tags, that indicate how the

auxiliary files should be built. JRun senses modifications to the source file and

automatically builds the auxiliary files (such as interfaces and deployment descriptors).

For more information, see

JRun Programmer’s Guide

Pointbase database server

JRun includes a restricted version of the PointBase Server Database Management

Software (DBMS). This is an all-Java database used with the JRun sample applications.

You can use this database server for your evaluation and development work. For more

information on the PointBase database, see the PointBase documentation, located in

jrun_root

/pointbase/docs. (

jrun_root

is the directory into which you installed JRun.)

JDBC Drivers

JRun embeds type 4 JDBC database drivers that provide connectivity to all major

databases.

Sample applications

The samples JRun server contains a variety of applications that illustrate a number of

coding techniques. The following table describes the samples applications that are

included with JRun:
