You can install the AS/400 Toolbox for Java classes on your workstation or on the AS/400.
In some cases, serving the classes from the workstation is a better solution than serving from the AS/400:
Choosing to install the AS/400 Toolbox for Java classes on your AS/400 gives you a centralized administration point for maintaining the classes.
Performance tip:
For performance reasons, you may want to place the AS/400 Toolbox for Java files on your workstations rather than accessing the files remotely across the network.
If your Java program runs on the AS/400 Java Virtual Machine (JVM), you can improve performance if you create an AS/400 Java program from the AS/400 Toolbox for Java zip file or jar file. Enter CRTJVAPGM on an AS/400 command line to create the program. (See the online help information for the CRTJVAPGM command for more information.) By using the CRTJVAPGM command, you save the AS/400 Java program that is created (and that contains the AS/400 Toolbox for Java classes) when your Java program starts. Saving the AS/400 Java program that is created allows you to save startup processing time. You save startup processing time because the AS/400 Java program does not have to be re-created each time your Java program is started.
