Re: [rules-users] KnowledgeAgent exception while trying to deserialize KnowledgeDefinitionsPackage
I revised my method to write a single package and to use the Drools stream
classes:
KnowledgePackage pkg = packages.iterator().next();
DroolsObjectOutputStream out;
try {
out = new DroolsObjectOutputStream(new FileOutputStream(outFilePath));
DroolsStreamUtils.streamOut(out, pkg, Boolean.TRUE);
out.close();
} catch (IOException ex) {
logger.debug(ex.getMessage());
}
I tested this with the compression option and without, but knowledge agent
still cannot deserialize. I now get exception:
Caused by: java.io.OptionalDataException
