How to use an Applet with multiple-jars
Hi everybody,
I would like to use an applet with multiple-jars.
ex:
"""
<applet codebase="." archive="main.jar,Addon1.jar,Addon2.jar" code="Appl.class" id="MyTest" width="600" height="30">
<param name = "MyParam" value = "1;2">
</applet>
"""
An applet with :
-> 1 Main JAR
-> X Addon JARs (X : a parameter "PRM")
My main part knows the parameter "PRM" -> knows which addon to use
My question is, how do I use classes from addons, inside the main part (and vise-versa if possible) ?
Thanks in advance
Best regards

I try what you say :
=== HTML ===
<applet codebase="." archive="Main.jar,Addon1.jar" code="Test.Appli.class" id="MyTest" width="600" height="30">
<param name = "myPrm1" value = "1;2">
</applet>
===MAIN JAR ===
package retest;
interface InterfAddOn1 {
public void AfficheTest1(String sStrTest);
}
public class Ctest {
public Ctest() {}
public void unTest(String sClassNameR) {
String sClassName = "PackTestAddon.TestClass1";
try {
Object oObj = Class.forName(sClassName).newInstance();
((InterfAddOn1) oObj).AfficheTest1(" Hello World ");
} catch (ClassNotFoundException ex1) {
System.out.println("ERR Class not found");
} catch (IllegalAccessException ex1) {
System.out.println("ERR Illegal Access");
} catch (InstantiationException ex1) {
System.out.println("ERR Instantiation Exception");
}
}
}
===ADDON JAR ===
package PackTestAddon;
public interface InterfAddOn1 {
public void AfficheTest1(String sStrTest);
}
--
package PackTestAddon;
public class TestClass1 implements InterfAddOn1 {
public TestClass1() {}
public void AfficheTest1(String sStrTest) {
System.out.println("Test :"+sStrTest);
}
}
I have this error :
