Hi,
I am working on unit tests for the mail services. They run JBoss 3.2.4RC1 "embedded",
by calling the following from their setup() method:
| //Start JBoss
| ServerImpl impl = new ServerImpl();
| System.out.println("got the server impl");
| Properties prop = new Properties();
| prop.setProperty(ServerConfig.HOME_DIR,(new File(".")).getAbsolutePath());
|
prop.setProperty(ServerConfig.ROOT_DEPLOYMENT_FILENAME,"src/META-INF/depends-service.xml");
| prop.setProperty(ServerConfig.SERVER_CONFIG_URL,"file:"+(new
File(".")).getAbsolutePath());
| System.out.println("done setting up properties");
| impl.init(prop);
| System.out.println("impl.init is finished");
| impl.start();
| System.out.println("impl.start done");
| alreadyrun = true;
| System.out.println("done configureMBeanServerFactory");
|
| //Start MBeans
| MBeanServer mbserver = JBMailJMXUtil.locateJBoss();
| ObjectName oname = new
ObjectName("jboss.mail:type=MailServices,name=UserRepository");
| StaticUserRepository sur = new StaticUserRepository();
| sur.addUser("acoliver","test");
| sur.addUser("test","testpw");
| sur.addUser("jboss","jbosspw");
| mbserver.registerMBean(sur, oname);
|
| //Start other MBeans here
|
|
Until now we have been running JNDI with a mock context for JNDI, but since JBoss is
actually being started, I am trying to use the existing NamingService, but have run
into problems.
I have set up the jndi.properties file to be:
| java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
| java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
|
I stepped through the org.jboss.naming.NamingService.startService() method. The first
bit loads up the properties from the jndi.properties file and sets them in
System.properties, as expected there is no java.naming.provider.url there. Also, when
I do a System.getProperty("java.naming.provider.url") at any stage nothing is
returned.
However, once the first InitialContext is created and it's environment got,
java.naming.provider.url is there! (i.e. it is in env below, but
System.getProperty("java.naming.provider.url") still returns nothing)
Code:
| InitialContext iniCtx = new InitialContext();
| Hashtable env = iniCtx.getEnvironment();
|
I followed this through, and new InitialContext()
calls javax.naming.InitialContext.init() //This initialises the environment for the
InitialContext
which calls javax.naming.internal.ResourceManager.getInitialEnvironment() //"produces"
the environment for the InitialContext
which calls javax.naming.internal.VersionHelper.getJndiProperties()
VersionHelper.getProperties() looks like this
|
| String[] getJndiProperties() {
| if (getSystemPropsFailed) {
| return null; // after one failure, don't bother trying again
| }
| Properties sysProps = (Properties) AccessController.doPrivileged(
| new PrivilegedAction() {
| public Object run() {
| try {
| return System.getProperties();
| } catch (SecurityException e) {
| getSystemPropsFailed = true;
| return null;
| }
| }
| }
| );
| if (sysProps == null) {
| return null;
| }
| String[] jProps = new String[PROPS.length];
| for (int i = 0; i < PROPS.length; i++) {
| jProps
| = sysProps.getProperty(PROPS
| );
| }
| return jProps;
| }
|
| String getJndiProperty(final int i) {
| return (String) AccessController.doPrivileged(
| new PrivilegedAction() {
| public Object run() {
| try {
| return System.getProperty(PROPS
| );
| } catch (SecurityException e) {
| return null;
| }
| }
| }
| );
| }
|
|
In this funky looking code (in which to be honest I don't understand the special
AccessController/PrivilegedAction bits) java.naming.provider.url and
jnp://localhost:1099 are returned. I'm wondering
a) Why doesn't this appear in JBoss itself when starting that without the
java.naming.provider.url in the jndi.properties
b) What the AccessController stuff does special to magically create the
java.naming.provider.url=jnp://localhost:1099
c) If I change the test target in the ant build file to run only one of the tests, and
make that test call
ResourceManager.getInitialEnvironment(null).get(Context.PROVIDER_URL) BEFORE I have
done anything to start the embbeddd JBoss it still returns a URL.
I'd like to not have java.naming.provider.url=jnp://localhost:1099, in order to run
the naming service "in-jvm" since I am experiencing other problems if I set the Port
and RmiPort > -1. If needed I can describe in more detail what they are.
Any ideas?
Cheers,
Kab
