[rules-users] Serialization issue

[Eric Miles]

All,

I'm using Xstream for serialization in my project.  I am having an issue
after deserializing a package in that application's classloader can't
find a generated class created by Drools for a function.  When I look at
the serialized XML, I see an entry for the class:

<entry>
<string>com/kronos/webta/service/smarttime/rules/CalculateTotal.class</string>
...
</entry>

When I step through the Package being deserialized, I see the proper
function name if the functions list (calculateTotal) as well as I see
com.kronos.webta.service.smarttime.rules.CalculateTotal.calculateTotal
listed as a static import.

However, when I go to actually run this rule I get the following:

java.lang.NoClassDefFoundError:

Anyone have any idea about how to go about finding out what the issue is?

Thanks in advance.
