hi ,

First of all congratulations to you for JBRMS release.
You and your team has done a great job.


Micheal I am facing some issue , when I use jbrms.

I have written a sample technical rule by following all the steps as
mentioned in the document.
I am able to download binary package also,but when I tried to use this
package in my rule engine class using following code it's giving some
error like ...


 FileInputStream fis = new FileInputStream( "C:/drools/TestPackage.pkg"
);
 ObjectInputStream ois = new ObjectInputStream( fis );
 Object objPackage = ois.readObject() ;
 
 when  ObjectInputStream object tries to read the object , its giving
some  an error 

  ois.close();
  fis.close();

Could you please help me out for this ...
