FULL PRODUCT VERSION :
java version "1.5.0_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_02-b09)
Java HotSpot(TM) Client VM (build 1.5.0_02-b09, mixed mode)
ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]
EXTRA RELEVANT SYSTEM CONFIGURATION :
Java(TM) Plug-in: Version 1.4.2_07
Using JRE version 1.4.2_07 Java HotSpot(TM) Client VM
MSIE Version 6.0.2900.2180.xpsp_sp2_rtm.040803-2158
A DESCRIPTION OF THE PROBLEM :
Retrieve an array from one applet and via Javascript use the array as an argument to a public method in another applet running in another page does not work. It works fine when the type of the array is java.lang.String, so I imagine primitive types work also. However, when use an array with a type which is proprietary to our applet, it cannot find the method in the Applet class and I get an exception in the Java console. I tested this with the Mozilla browser and it works fine in Mozilla with the same Java plug-in.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Open the test.html file outlined below ensuring that the classes are in the classpath. Also, pop-ups and active content must not be blocked.
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Expected the method to get called which would produce output in the Java console indicating it was called.
ACTUAL -
testMethod called
testMethod called with testString
java.lang.Exception: setTestArray{0} :no such method exists
