[rules-users] How to create binary package

[Barfield Steve]

Is Package.writeExternal(ObjectOutput) the best way to create a binary file of your package that can be read by BinaryRuleBaseLoader.addPackage(InputStream) ?

 

Having generated a package using standard code, I've tried to create a binary file of the package for deployment as below. 

 

But when BinaryRuleBaseLoader reads the binary file it raises :

Can only add instances of org.drools.rule.Package to a rulebase instance.

 

Looking inside the binary file I can see it doesn't have the first line :

 

’__sr__org.drools.rule.Package_______@

 

which is found in packages downloaded from JBRMS. So this code isn't quite working. Please can you help.

 

builder.addPackageFromDrl(source);

Package pkg = builder.getPackage();

try{

        FileOutputStream tempFile = new

        FileOutputStream("my.pkg");

        ObjectOutput oos = new ObjectOutputStream(tempFile);

         pkg.writeExternal(oos);

         oos.flush();

         oos.close();

                   

          tempFile.flush();

          tempFile.close();

}           

catch(Exception e){

            System.out.println(e.toString());

}
