Re: [Simple-support] obligation of "static public class" ?

[Patrice B. <pat...@sm...>]

Hi (& thanks),

I'm getting a NoSuchMethodException   (...) <init>(). 

Just like mentionned in

*[Simple-support] Problem deserializing an inner class
<http://sourceforge.net/mailarchive/message.php?msg_name=48AF5691.5040103%40znyx.com>*
From: Alan Deikman <Alan.Deikman@zn...> - 2008-08-23 00:15

java.lang.NoSuchMethodException: com.test.Outer$Inner.<init>()
  at java.lang.Class.getConstructor0(Class.java:2706)


I don't have my IDE at hand right now so I can't copy/paste, but that's
the exception.

An I see you answered "The inner class needs to be static. Otherwise it
can not be instantiated reflectively."

But none of the sample in tutorial have this "public static" attribute
for inner classes.   And when I do make it public static, I still get
the same exception.
