This has come up multiple times on the mailing list - essentially it
can not/should not be done. Please see
http://wiki.apache.org/tomcat/FAQ/Password for details
While generally that is correct, JNDIRealm plus Windows authentication
is a special case.
It should be possible to remove the connectionName and
connectionPassword attributes from the above configuration. See the JNDI
docs and the useDelegatedCredential attribute in particular.

Any idea what I am getting wrong?
@Daniel, I have configured jmx with Spring and I get a numIdle of 0 and
numActive of 2 after the problem occurs. This confirms what you and Chuck
say: my app leaks db connections.
However, I am still not sure why my app leaks the connections. I use the
default Spring configuration...

question so I should post it elsewhere.

In your case, the timeBetweenEvictionRunsMillis check will happen every
180 millis, which is 1800 seconds, which is every 30 minutes for
connections that have been idle the same period, which may mean that
they don't qualify for eviction for over 30 mins, which in turn would

Maybe you should reduce that number during testing.

Yes, I meant maxActive, sorry.
Why use a DeferredResult here if you're just setting the result

@Daniel, I have configured jmx with Spring and I get a numIdle of 0 and
numActive of 2 after the problem occurs. This confirms what you and Chuck
say: my app leaks db connections.
However, I am still not sure why my app leaks the connections. I use the

You're right. I should set the result in another method/thread i.e. a post

Is this related to the memory leaks?

You might try adding in removeAbandonedTimeout and setting it really low. It
defaults to 300 seconds.

Diagnosing Silently Frozen Tomcats
When tomcat freezes silently, what is the best way to look inside the frozen tomcat or java instance and see the cause? We have 1500+ tomcat instances, and most of them run great most of the time. But a few times per week, an instance will become unresponsive. There is usually nothing suspicious in the tomcat or gc logs. There are no OOMEs and we don't see any full GC's that take more than 0.25 seconds. The process does not die. It stays running and the port is still listening, and you can even telnet to the port, but tomcat does not answer any requests until you restart it. Is there a way to peer into the frozen instance and see what's up? We use tomcat 6.0.16 and java 6.0.21 on RHEL 5 and RHEL 6. -- Eric Robinson Disclaimer - March 22, 2013 This email and any files transmitted with it are confidential and intended solely for users@tomcat.apache.org.

For those who don't know the species : It is a very strong, sturdy bird. Rather bad-tempered too, you shouldn't mess with it. It is a bit the bird-equivalent of the Belgian horse really. It has a big round head, with a strong beak, say oh a good 5 inches wide and 7 inches long. A really strong beak, he can crush nuts or bones with it. Then it has very strong wings too, strong enough to lift a small sheep for instance (or a bowling ball for that matter). And tough feathers, you can make brooms with them. And also rather short, but very strong sturdy legs; like 2 inches thick and 2 inches long. And then its balls, no kidding, they are the size of coconuts. And each time it lands, it goes oye oye oye. That sounds absolutely terrifying. A 7-inch-long beak that's 5-inches wide? That's like an oil tunnel for a car.

Re: Executable Tomcat JAR/WAR executes fine standalone, classloading errors in JNLP
On Mar 21, 2013, at 4:31 PM, Nick Williams wrote: I have built an executable Tomcat JAR file. It has all of the Tomcat classes and dependencies zipped into one big JAR. Inside that JAR is also a WAR file, the native DLL, and logging.properties. My com.ul.io.Bootstrap class creates an .extract directory in the CWD, extracts the native DLL, WAR file and logging.properties, configures Tomcat logging, configures a Tomcat class instance, adds the WAR file is a web app, starts the Tomcat class instance, and waits for it. If I run this JAR like this: java -jar PeripheralProxy-1.0.0.SNAPSHOT.jar Everything works fine. It starts up, I can go to the application, no errors in the logs ... everything is perfect. The output from stdout is below if you're interested. Now, I take the same JAR file and sign it with the jar signer. To make sure nothing got messed up, I run the signed JAR file: java -jar PeripheralProxy-1.0.0.SNAPSHOT-signed.jar This worked to. Exact same stdout output, application works fine. Perfect! Next I created a JNLP file with, among other things, security set to all-permissions /. I open the JNLP file in my browser. It accepts the certificate and starts the JAR file. First problem is logging doesn't work. Not sure why. I had to enable the Java console in Java Control Panel to see what was going on. 1) It created the .extract directory, so the first step worked. 2) It extracted the WAR file, native DLL and logging.properties without a problem, so that worked, too. 3) It could not deploy the application. At this point it began getting class loading errors. The output from the Java console is also below. Anyone have a clue what went wrong? Obviously the classes ARE in the JAR file, otherwise it wouldn't work from the command line. snip Well, I got this working. I'm not sure anyone has ever successfully done this before, because I didn't really find much of anything on Google that helped. Here's what I had to do: 1) Sign the JAR and use all-permissions /. This was a given and I was already doing this. 2) Use tomcat-embed-logging-log4j instead of tomcat-embed-logging-juli. The Web Start deployer is NOT friendly to the way JULI deals with class loaders. 3) Don't put ANY classes in the WAR files included in the JAR file. ALL classes (Tomcat AND application AND dependency classes) must go in the root/embedded/same JAR. Otherwise the security manager detects that they were loaded differently and doesn't apply the all-permissions / rule to them. There IS an alternative to this: System.setSecurityManager(null). But that's not pretty, and discouraged. 4) After instantiating the Tomcat instance and before starting it, set the parent class loaders to the current thread context class loader. Otherwise Tomcat tries to use the System class loader. You cannot use the System class loader in Java Web Start. None of the application classes are loaded by it. Tomcat tomcat = new Tomcat(); ClassLoader loader = Thread.currentThread().getContextClassLoader(); tomcat.getEngine().setParentClassLoader(loader); tomcat.getHost().setParentClassLoader(loader); tomcat.getServer().setParentClassLoader(loader); tomcat.getService().setParentClassLoader(loader); 5) Patch JarScanner. The JarScanner only scans JARs at URLs starting with file: and jndi:. It ignores http: and https: URLs, and in Web Start, all JAR URLs start with http: or https:. I filed bug 54745 about this, because it's a noninvasive patch that I think improves Tomcat. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
