Sergey,
of course Mark is right - you shouldn't use readExternal and the default
constructor.
this was my fault from an earlier mail.
please try something like this:
// EXPORT
...
FileOutputStream fos .....
...
ObjectOutputStream oos = null;
try {
oos = new ObjectOutputStream(fos);
oos.writeObject(builder.getPackage());
oos.close();
} catch (final IOException e) {
... your code....
}
...
// IMPORT
FileInputStream fis...
...
ObjectInputStream ois = null;
try {
ois = new ObjectInputStream(fis);
builder = new PackageBuilder((Package)ois.readObject());
ois.close();
} catch (final IOException e) {
...your code...;
} catch (final ClassNotFoundException e) {
...your code...;
}
now your imported package should work like the exported

Ekke,
Started using 4.0.2, but getting same error.
This is how I am loading the Package :
this.pkg = new Package();
this.pkg.readExternal(ois);
Does that look right to you?

sergey,
just tried it:
exported a package with rules as stream
(using the writeExternal() from Package)
then in another run I created new RuleBase, added new Package,
then import the rules into this empty Package (using the readExternal()
from
Package)
then added some facts, execute the rules,
tested if all rules are there,
tested if the Facts are in workingMemory - all ok
(using snapshot 4.0.2, eclipse 3.3, osx 10.4.10)
