updates for the plugin framework for Grouper

  • (hopefully) better classloader configuration
  • updated webapp for testing
  • osgi security. Note that the security update is the first step toward setting up a plugin market, allowing for pulling remote jars and verifying trusted signed artifacts.

update osgi system packages
update osgi boot delegation
deprecate old namespace
use full location for bundle rather than just the file name
move property names to constants
add osgi security configuration
add tests and testing resources for osgi seucrity
see if I can slip the change to index.jsp so I can run in jetty :-D
update test webapp to allow disabling debug

** NOTE: the org.apache.felix.framework.security.jar is a locally modified version that has a fix for checking trusted certificates. this should be moved into the grouper repo or submitted to the upstream project.

do we continue to use osgi namespace, or do we use more generic plugins?

after our previous conversation, should likely be the opposite. since the grouper project has no intention of implementing osgi, some other term should be used. this statement is true for all questions related to osgi, something else should be used and documented.

packagesForBootDelegationString = GrouperConfig.retrieveConfig().propertyValueString("grouper.osgi.framework.boot.delegation");
Set<String> packagesForBootDelegation = new HashSet<>();
if (null != GrouperConfig.retrieveConfig().propertyValueString(GROUPER_OSGI_FRAMEWORK_BOOT_DELEGATION)) {
LOG.warn("You are setting a value for `grouper.osgi.framework.boot.delegation`. This is generally not needed adn should not be used unless there is a good reason to do so");

typo

packagesForBootDelegation.add("org.osgi.*");
packagesForBootDelegation.add("javax.*");
packagesForBootDelegation.add("org.apache.commons.logging");
packagesForBootDelegation.add("edu.internet2.middleware.grouper.*");

need to check this, but could cause a problem if a plugin ends up in the classpath (e.g. class clash)

commented elsewhere, this policy seems dangerous, but this functionality is deprecated. followup on osgi plans

String keyStorePassword = "changeme";
keyStore.load(null, keyStorePassword.toCharArray());

might be better to move this out of the classpath, perhaps to WEB-INF/plugins?

I think I remember why this is here, but need to verify: ddls for some reason were missing from the classpath

Recommend removing this. This is the list of modules that are built and published at every release, and for which documentation is built. You can always build this manually, even if it's not in this list.
