Applet parameters

Creating a web page which will load JET 6530
The portion of JET 6530 which runs inside the user's web browser is known as a Java^TM applet. The applet is a set of class files. Class files are the compiled Java code. These class files are provided with the JET 6530 distribution as a JAR file (JET6530J.jar).

To include a JET 6530 applet in a web page, the web page needs to include an <APPLET> tag that specifies CODE=com.platypuspartners.jet6530.JETApplet6530.class.

The applet also needs a space on the screen into which it can draw. This is specified by the WIDTH and HEIGHT attributes of the <APPLET> tag.

There are several web page editors that will allow you to insert a reference to an applet without the web page designer being aware of the HTML commands that the editor generates. It is equally valid for the web page designer to use such an editor so long as the CODE, ARCHIVE, WIDTH and HEIGHT attributes are set correctly. Note also that class file names are case sensitive. For newer versions of Java from Oracle, you also require the "jnlp_href" attribute.

Although there are many other class files for the JET 6530 applet stored in the JET6530J.jar file, the web page designer need not specify these in the <APPLET> tag. The web browser will automatically identify the other class files that the JET 6530 applet needs.

Applets can be "configured" by including parameters embedded in the <APPLET> tag. The web page designer can include parameters using <PARAM> tags. Refer to Applet Parameters for more information.

Applet parameters

Applet parameters appear in the web page used to load JET 6530. They are used to configure JET 6530. For example, applet parameters specify the names and URLs of web sessions that JET 6530 users can open.

Applet parameters are specified with <PARAM> tags enclosed by the <APPLET> and </APPLET> tags. An example of an <APPLET> tag which loads JET 6530 and specifies two web sessions, is:

<APPLET CODE=com.platypuspartners.jet6530.JETApplet6530.class
ARCHIVE=JET6530N.jar jnlp_href="JET6530.jnlp" WIDTH=300 HEIGHT=40>
<PARAM NAME="web_session_name_1" VALUE="locis">
<PARAM NAME="web_session_url_1" VALUE="http://www.acme.com/jet6530/sessions/locis">
<PARAM NAME="web_session_name_2" VALUE="Accounts">
<PARAM NAME="web_session_url_1" VALUE="http://www.acme.com/jet6530/sessions/acc">
<PARAM NAME="last_web_session" VALUE="2">

Your Web Browser is not currently Java-enabled.

The following table lists the JET 6530 applet parameters

If a parameter name is not specified correctly, or its value is invalid, JET 6530 uses the default value for that parameter.
