Re: [rules-users] OSGI, classloading, and imports in KnowledgeBuilder
Hi Marcel,
I'm running into the exact same problem as you did. I have an
OSGI
bundle
where I embed Drools and all the dependencies and I'm deploying
it on
FUSE
4.0 . I tried passing the classloader posted on this thread to Drools
but
still the same problem. I don't understand when you talk about
the
imports
where they should be placed and which imports.
The imports I was talking about was the ones embeded in the Descision
tables.
Depending on your spreadsheet editor the imports may have a tendency to
hide themselves ;-(
A neat trick when working with Decision Tables is to convert them to the
rule format.
Something like the below lines will achieve this:
public String compile(String path) {
String drlStr = "";
try {
Resource pathResource =
ResourceFactory.newClassPathResource(path, getClass());
DecisionTableConfiguration dtableconfiguration =
KnowledgeBuilderFactory.newDecisionTableConfiguration();
dtableconfiguration.setInputType(DecisionTableInputType.XLS);
drlStr =
DecisionTableFactory.loadFromInputStream(pathResource.getInputStream(),
dtableconfiguration);
} catch (IOException e) {
e.printStackTrace();
}
return drlStr;
}
Kind regards
Lasse Wallentin
