I have the name of a clas.s and the name of the method in it - in a
String format. How to call this method with jdk 1.5.
/**
* params can be null.
*/
public void call(String clazz, String method, String [] params ){

}

Thanks

Example (from so code I had):

public static void c(Object o, String methodName, String a, String b) {
try {
Class declarg[] = new Class[2];
declarg[0] = String.class;
declarg[1] = String.class;
Method m = o.getClass().getMethod(methodName, declarg);
Object callarg[] = new Object[2];
callarg[0] = a;
callarg[1] = b;
m.invoke(o, callarg);
} catch (Exception e) {
}
}
