How to send a dynamic Parameters to an Applet

Question

Hi,
I want to know how can I send parameters dynamically to an applet.
I have a senaria like this,
<applet code="com.test.thinclient.ThinClientApplet" codebase="http://localhost:8090/bluenote/" width="260" height="400" archive="webcaller-01.01.01.00.jar">
<param name="properties" value="http://localhost:8090/test/config/webcaller.properties">
<param name="ui_definition" value="http://localhost:8090/test/config/webphone_ui.xml">
<param name="ss_callback_param_pair_1" value="name,username">
<param name="ss_callback_param_pair_2" value="account,password">
</applet>
In tha above code the server URL will be change,and the username and password also will be chaged dynamically. useraname will be loaded as loggend in user.
How can I send those values dynamiclly.
-Thanks

Hi,
you have at least the following options:
a) use javascript to exchange information between the browser (or an application) and your applet. The MAYSCRIPT attribute of your applet should be enabled.
b) each time your <param> values changed, reload a "hidden" iframe containing html code with another small applet and modified <param> values. Assuming that the codebase and archive attributes of this and your applet are the same, both applets run in the same context. By registering your applet in a static Hashtable at startup, you can access it later from the hidden applet and send your modified <param> values. There may a little delay because the browser has to load new html content (the applet class itself is loaded just once).
c) simply reload the frame with the applet itself and modified <param> values :-)
Hope that helps.
