Building Java Applications for the iSeries Server with VisualAge for Java 3.5

132 Building Java Applications for the iSeries Server with VisualAge for Java 3.5

򐂰 Display IFS directory contents in an HTML list or a hierarchical tree

򐂰 Graphically present information about JDBC data sources and user-defined resources

򐂰 Display any resource in a servlet

򐂰 Use support the for JDBC 2.0 Optional Package extensions

򐂰 Work with iSeries environment variables

򐂰 Request a license for a product installed on the iSeries

򐂰 Query and modify the state and configuration of the iSeries NetServer

򐂰 Ping the host servers from a command line or within a Java program

Enhanced classes

The IBM Toolbox for Java Modification 4 also includes enhancements to existing classes.

These enhancements offer:

򐂰 Improvements in IFS list processing

򐂰 Added methods to the CommandCall, ProgramCall, and ServiceProgramCall classes to:

– Get the Job ID of the job actually running the command, program, or service program

– Provide a way to directly call the command, program, or service program on the same

thread as the application, instead of calling by way of a server (when running on the

iSeries JVM)

– Indicate if the iSeries command, program, or service program is thread-safe

򐂰 The ability to use SSL to encrypt connections between proxy clients and proxy servers

򐂰 User-defined grouping of system values

򐂰 An easier way to load and access additional message help text

New or enhanced functions

The IBM Toolbox for Java Modification 4 also features new and enhanced functions:

򐂰 Faster string conversions are provided

򐂰 Better NLS support for system and error messages

򐂰 HTTP tunneling support for connecting between proxy clients and proxy servers

Additional functions and features in Graphical Toolbox

The Graphical Toolbox incorporates these new features:

򐂰 The PDML framework now uses Java Help

򐂰 The GUI Builder now includes context-sensitive help

򐂰 Changes in the MessageViewer allow you to retrieve second level text for iSeries

messages and include them in your own HTML detail help

4.3 IBM Toolbox for Java and host servers

This set of interfaces provides the infrastructure needed to create and maintain socket

connections to the iSeries servers, send and receive data streams, and handle a sign-on.

This group of classes includes a private iSeries security manager class that maintains a list of

validated iSeries servers and sign-on information for the system. These classes use the

sign-on server and the central server to interact with the iSeries server. See Figure 4-3.
