Pass dynamic Command line arguments

Question

Hi,
I tried to pass dynamic command line argument to Web start using the method :
"javaws URL -D foo -D bar"
as explained in the "Unofficial JWS/JNLP FAQ" that " You can pass your own system properties to your app using -D switch ....", but I got the following error at the start;
error occurred while launching/running the application.
Category: Invalid Argument error
Too many arguments supplied: {http://...URL/my.jnlp, -Did=123 }
p.s. I already added the"<property name='' value=''/> in the <resourse>, and modified the main class to get the parameter using System. getProperty();
Did anyone try to this method before? What's wrong of this?
Thanks in advance for your help.

Thanks.
here below is the jnlp file:
<jnlp spec="1.0+" href="$$name" codebase="$$codebase">
<information>
<title>GUI Application</title>
<vendor>PS</vendor>
<description>PS GUI WebStart Version</description>
<icon href="logo.jpg" />
<offline-allowed />
</information>
<resources>
<j2se version="1.3" />
<jar href="lib/gui.jar" />
<property name="id" value="zbc" />
<jar href="lib/classes12.zip" />
<jar href="lib/j2ee.jar" />
<jar href="lib/jaas.jar" />
<jar href="lib/jce1_2_1.jar" />
<jar href="lib/jdom.jar" />
<jar href="lib/xerces.jar" />
<jar href="lib/local_policy.jar" />
<jar href="lib/log4j.jar" />
<jar href="lib/orion.jar" />
<jar href="lib/sunjce_provider.jar" />
<jar href="lib/US_export_policy.jar" />
</resources>
<security>
<all-permissions />
</security>
<application-desc main-class="GUIFrame">
</application-desc>
and in the main class "GUIFrame", i use System.getProperty("id") t get the parameter, if I hardcode the value of the "id" in this jnlp file and use javaws URL, everything's fine, but not the "javaws URL -Did=value" which will return the error as mentioned.
Thanks again for your help.
