[rules-users] RE: rules precompilation

[Manukyan, Sergey]

wtf? you shouldn't be touching those methods, those are part of the
internal serialisation process. In fact you shouldn't instantiate a
Package at all, either serialise in an existing one 

 

So you mean do this? :

 

      ois = new ObjectInputStream(fis);

      this.pkg = (Package) ois.readObject();

      ois.close();

 

It did the same thing... threw same exception...

 

 

or use the PackageBuilder

 

            How? Where is it described? Are there any examples?

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?
  

wtf? you shouldn't be touching those methods, those are part of the
internal serialisation process. And you should never instantiation a
Package with the default constructor, the javadocs even state that. In
fact you shouldn't instantiate a Package at all, either serialise in an
existing one or use the PackageBuilder.

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)

	Sergey,
	 
	I am using precompiled rules.  Serializing instances of
	org.drools.rule.Package works for me.
