Description
When using the folowing jsp with Tomcat 5.5.15 and Sun JDK 1.5.0_06 for windows, the inner class object can be serialised but on de-serialisation a CannotResolveClassException is thrown claiming it cannot locate the inner class.
JSP:
<%@ page import="com.thoughtworks.xstream.*" %>
<%!
public static class Example
{
String comments="Hello";
public Example(){}
}
%>
<%
XStream xstream = new XStream();
xstream.fromXML(xstream.toXML(new Example()));
%>
Stack Trace:

Hi Chris,
this is nornal, since XStream has no knowledge about the classpath for the generated code. You must provide a proper ClassLoder in this case, following should do:
XStream xstream = new XStream();
xstream.setClassLoder(Example.class.getClassLoader());
xstream.fromXML(xstream.toXML(new Example()));
Please, feel free to reopen this issue, if this does not help.

P.S. Using XStream 1.1.3
