Parameters in applet project

Ignition
1

I’m trying to pass parameters a project in applet mode, I’m using the code of a previuos posts:

from javax.swing import JApplet
from javax.swing import SwingUtilities
applet = SwingUtilities.getAncestorOfClass(JApplet, event.source)
value=applet.getParameter(“paramName”)

and I get the instance of the applet without problems but when I try to get the parameter I have None.

I try to use the function applet.getParameterInfo() to check that I have parameters and I’m getting None too.

I’m using Ignition version 7.6.4.

Any suggestions?

Try using the parent window instead of the event source:

from javax.swing import JApplet
from javax.swing import SwingUtilities
applet = SwingUtilities.getAncestorOfClass(JApplet, system.gui.getParentWindow(event))
value=applet.getParameter("javaws.sr.project")
system.gui.messageBox(value)

I try using the parent window but get the same result.

I pass in the URL the parameter named ‘User’ and I try to get this value like this:

from javax.swing import JApplet
from javax.swing import SwingUtilities
applet = SwingUtilities.getAncestorOfClass(JApplet, system.gui.getParentWindow(event))
user=applet.getParameter(“User”)

Is this correct? or I have to use another name for the parameter? I ask this because when I use “javaws.sr.project” as the parameter I get the correct name of my project.

Thanks

You need to post the HTML or fix it there.

Applet parameters come from the HTML:

<div class="applet">
	
	<script>
	var attributes = {
		"codebase":"http://localhost:8088/main/system/launchbin/",
		"archive":"launchclient.jar",
		"code":"com.inductiveautomation.ignition.client.launch.BootstrapApplet",
		"width":"800",
		"height":"600"};
	var parameters = {		"classloader_cache":"false",
		"javaws.sr.gateway.addr.0":"localhost:8088:8043/main",
		"javaws.sr.scope":"C",
		"javaws.sr.project":"TestProject",
		"javaws.sr.launchts":"1396974861926",
		"javaws.sr.main":"com.inductiveautomation.factorypmi.application.runtime.ClientLaunchHook"};
	deployJava.runApplet(attributes,parameters,'1.6');
</script>
	
</div>

I have this HTML:

[code]

<script>
var attributes = {
	"codebase":"http://192.168.111.165:8088/main/system/launchbin/",
	"archive":"launchclient.jar",
	"code":"com.inductiveautomation.ignition.client.launch.BootstrapApplet",
	"width":"800",
	"height":"600"};
var parameters = {		"classloader_cache":"false",
	"javaws.sr.gateway.addr.0":"192.168.111.165:8088:8043/main",
	"javaws.sr.scope":"C",
	"javaws.sr.project":"SentinelIPG",
	"javaws.sr.launchts":"1396979112158",
	"javaws.sr.main":"com.inductiveautomation.factorypmi.application.runtime.ClientLaunchHook"};
deployJava.runApplet(attributes,parameters,'1.6');
[/code]

I don’t see my parameter anywhere. How can I set a parameter in the HTML?
