the drools jars aren't signed AFAIK, so it must be another jar causing
the problem.
Debug and take a look which jar is being loaded.
In that jar you 'll find a META-INF/MANIFEST.MF file with signed hashes
and META-INF/*.RSA and *.SF file which is the signing key.
Not that signing an already signed jar corrupts the jar. For example,
during your webstart signing.
With kind regards,

I have created a plugin to contain the core Drools jars and
dependencies, and this plugin is then used by my RCP. This works, a
couple rules fire correctly, etc. Now I want to set up a testing
framework (JUnit4) and have the following code, which causes an Invalid
signature file error. My core plugin was created in Eclipse simply by
wrapping the Drools jars and dependencies, and as I said, the RCP itself
works. Any assistance is greatly appreciated.

@BeforeClass
public static void setUp() throws Exception {
Reader source;
final PackageBuilder builder = new PackageBuilder();
boolean exists = (new File("rules/GlucoseDroolRules00.drl")).exists();
if (exists) {
builder.addPackageFromDrl(new FileReader(
"rules/GlucoseDroolRules00.drl"));
} else {
System.out.println("Cannot locate the file - will try as resource");
source = new InputStreamReader(AllDroolsRulesTests.class
.getResourceAsStream("rules/GlucoseDroolRules00.drl"));
builder.addPackageFromDrl(source);
}
if (builder.hasErrors()) {
System.out.println(builder.getErrors().toString());
}
Package pkg = builder.getPackage();
ruleBase = RuleBaseFactory.newRuleBase();
ruleBase.addPackage(pkg);
}
The code dies in the line instantiating the PackageBuilder builder:
