Programmable Host On-Demand

Writing a Programmable Host On-Demand application

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

Host code pages

All applications require hacp.jar. If your application needs to support additional host code pages, it requires additional jar files.

The following table lists the component names for the host code pages:

Host code pages	Name
Base	hacp.jar
Arabic	hacpar.jar
Latin1a (de, es, fr, it, pt)	hacp1a.jar
Latin1b (other locales)	hacp1b.jar
Russian	hacpru.jar
Turkish	hacptr.jar
Latin2 (Central European)	hacpce.jar
Japanese	hacpja.jar
Korean	hacpko.jar
Chinese	hacpzh.jar
Chinese (Traditional)	hacpzhtw.jar
Hebrew	hacphe.jar
Thai	hacpth.jar
Greek	hacpgr.jar
Hindi	hacphi.jar

Font archives

The following table lists the archive names for the different font packages:

Font archives	Name
IBM Raster Fonts	hafntib.jar hafntap.jar
Arabic	hafntar.jar
Hebrew	hafnthe.jar
Thai	hafntth.jar

Supported languages

The following table lists the languages supported by Host On-Demand along with the jar files that contain the messages for that language. When the API is used, the Programmable Host On-Demand code detects the locale of the client machines and attempts to load the messages in that language if it is supported by Host On-Demand. If Host On-Demand does not support the client locale, it defaults to English.
