In many ways, applications are much easier than applets. Applications run on a client machine without a browser. A Java application requires the following to run:

• A suitable Java Virtual Machine installed on the client machine (Host On-Demand Version 11 requires a minimum level of JDK 1.5. and no longer supports Java 1 from this version onward.)
• Any necessary jar files
• The correct syntax to launch the application with all the necessary jar files in the Java classpath

Since the code is not downloaded across a network, the size of the jar containing the application is not an issue. We recommend that you use the following jar files for your application. All of these Host On-Demand archive files are installed on a server during the Host On-Demand install. You can copy them from the server to your client machines.

• hoddbg2.jar to access the full functionality of Host On-Demand

• If your clients need to use 5250 file transfer or 5250 data transfer (database access), then you must include ha5250x2.jar. If your clients need the SQL wizard for generating SQL statements, then you must include hasql2.jar. If your clients need to use TSL connections to a host, then you must include hasslite2.jar.

• hodimg.jar to supply the images used by Host On-Demand
• host code pages
• font archives
• Host On-Demand messages (see Supported languages)

You also need a jar file containing your application code.

The following command launches a Java application called MyApplication placed in myjar.jar, using English messages, US host code pages, and IBM Raster Fonts:

java -classpath myjar.jar;hoddbg2.jar;hodimg.jar;ha_en.jar;hacp.jar;hafntib.jar;hafntap.jar MyApplication
