Hmm. I think you need some better PCI auditors. If your app was running on Tomcat 5.0.x and you trust the app (which seems reasonable given it is doing something that requires PCI compliance) then an upgrade to 7.0.12 should be sufficient if you using the HTTP BIO connector. Indeed. In my experience, I'd expect a QSA/PCI Auditor to be far, far more conservative than to promote Tomcat 7.0.x as a 'safe' version compared to 6.0.recent. p Since Tomcat appears to behind httpd then there is a strong chance you are using AJP (BIO or APR), in which case 7.0.2 should be sufficient. It appears your current auditors are blindly (and wrongly) assuming any vulnerability in Tomcat will impact your installation. Expect a demand to upgrade to 7.0.19 when they get around to reading the Tomcat security pages again. snip/ It seems that the character arrays [C, java.lang.String and javax.servlet.jsp.tagext.TagAttributeInfo entries are considerably higher in Tomcat-7.0.10 than in Tomcat-7.0.8 and I am wondering if this could lead to an explanation for the difference. Maybe. What you really want to look at is the GC roots for those objects. That will tell you what is holding on to the references. Based on that data I'd start looking at the arrays of TagAttributeInfo but that might be completely the wrong place to look. I've just triggered a heap dump on the ASF Jira instance (running 7.0.19) to see what that looks like. I'll report back what I find (once the 4GB heap has finished downloading - it may be some time). Would anyone know of any changes between the two versions, possibly linked to those memory entries, that could lead to such behaviour? Nothing jumped out at me from the changelog. Any help or suggestions is greatly appreciated! I'm sorry for a long post, but hopefully its got the information needed to help diagnosis. To be honest, there isn't enough info hear to diagnose the root cause but there is enough to demonstrate that there is probably a problem and maybe where to start looking.

Hi there,
I am trying to list files and directories within an war-file i.e
images/summer2010 images/winter2010. The war-file is deployed on a tomcat 7

Since I have no exposed filesystem getRealPath will return null.
If you 'have no exposed file system', how do you expect to get files?

So I tried to use getResourceAsStream wich works fine for files but not for
directories.
My other idea was to use getResource and URL/URI to get a java.io.File via
JNDI. But this file is not a file nor a directory.
Cheers

Code Snippet:
// null if unpackWar = false
String absolute =
this.getServletConfig().getServletContext().getRealPath(files);
out.write(Files: + absolute);
// jndi
URL url =
this.getServletConfig().getServletContext().getResource(files);
out.write(br/ + url.toURI());
File f = new File(file: + url.toURI());
// Both null
out.write( isDir: + f.isDirectory());
out.write( isFile: + f.isFile());
InputStream is =
this.getServletConfig().getServletContext().getResourceAsStream(files/1.txt);
// NPE if directory

Hi, Pid-
For the sake of clarity, I'll repeat this here:
public class AServletContextListener implements ServletContextListener
{
private Timer timer;
private ATimerTask timerTask;
Yes, but why is the timerTask an instance field? Put another way, why
is there a reference to it outside of the contextInitialized() method?
public void contextInitialized( ServletContextEvent sce )
{
if ( timer == null )
{
Calendar firstRunTime;
timer = new Timer( true );
timerTask = new ATimerTask();
firstRunTime = new GregorianCalendar();
firstRunTime.set( Calendar.HOUR_OF_DAY, 12 );
firstRunTime.set( Calendar.MINUTE, 0 );
firstRunTime.set( Calendar.SECOND, 0 );
firstRunTime.set( Calendar.MILLISECOND, 0 );
timer.scheduleAtFixedRate(
timerTask, firstRunTime.getTime(), 1000 * 60 * 60 * 24 );
}
}
public void contextDestroyed( ServletContextEvent sce )
{
if ( timer != null )
{
timer.cancel();
timer.purge();
timer = null;
timerTask = null;
try
{
Thread.sleep( 1000 );
}
catch ( InterruptedException ie )
{
}
}
}
}
It isn't absolutely necessary but why would I make the ATimerTask
reference anything but private?
As above.
The only reason to keep a handle on the task itself is if you're calling
cancel on the task - but you aren't doing that. Maybe you should?
The timer tasks in the application perform some very straightforward
database and file system maintenance when their run methods are invoked
that might take up to half a second each. None override the cancel
method. All are scheduled to execute on a daily or weekly basis and
none at even close to the same time of day.
The timer.cancel() method doesn't interrupt or stop a running task
immediately, it just prevents it from running again.
Your timer creates as daemon threads - perhaps you could assign a name
too, and then report (just for confirmation) that it is the expected
thread name(s) Tomcat's complaining is still running?
Also, while testing for ways to prevent the error message from being
written to the logs, I commented out the run method bodies of the timer
tasks so that they returned immediately and, given that I know the
schedule, none of the timer tasks were executing when I stopped or
restarted Tomcat.
That reads (to me) like you're saying that if you comment out the run
methods, everything is OK. Is this correct?
p
The InterruptedException is caught and logged if it occurs. I've never
seen it in the logs.
Thanks.

You should be able to do a Thread.join() using the timer's Thread
object rather than sleeping.
But Timer doesn't expose its thread. An alternative would be use
something like Executors.newSingleThreadScheduledExecutor() to get a
ScheduledExecutorService. The executor can be used to schedule a
Runnable with a fixed rate or delay. When the context is destroyed,
shutdown the executor and await its termination.

Hi there,
My question is simple : is it possible to disable the cache of Tomcat ?
I think I've browsed the entire web about that without finding my answer.
As I'm developping a website under Eclipse, I would like to see modifications
as they are developped but here, when I change an image, for example, it's
always given from the Tomcat's cache : I can see, in the Console of Tomcat,
for each page I request, about 20 messages like this one :
{date and hour} DEBUG [http-8080-1] lutece.cache - URI served from cache :
/PSP/images/logo.png
What is 'lutece.cache'? That's not a log message Tomcat would output.
If I modifiy the logo.png, I can't see the new one in my browser, even if I
stop and restart Tomcat, even if I disable my browser's cache...
Are you sure that the file is actually being updated?
If you're stopping and starting Tomcat then you are terminating the
cache (which is in-memory), so it will pick up the new version.
Assuming you're using Tomcat's cache and not a third party one.

From looking at Tomcat 7.0.16's source, I can see that line 287 in
StandardWrapperValve is inside a catch block:
285 } catch (Throwable e) {
286 ExceptionUtils.handleThrowable(e);
287 container.getLogger().error(sm.getString(
288 standardWrapper.serviceException, wrapper.getName(),
289 context.getName()), e);
290 throwable = e;
291 exception(request, response, e);
292 }
So does that mean that another Exception/Error occurred, but was suppressed
by that NPE and therefore couldn't be logged?
What is the request for and is the config of your Tomcat instance
modified from the original download - if so, what has changed (config etc)?

So you meant the client or the server. I don't know the intricities of webapps yet in how they run. Probably a good idea to read up on that if you're going to build one. This thread was just trying to understand if I'm barking up the wrong tree. Your second paragraph is better phrased. which computer/'machine' is doing the binding? Whichever one the code for creating a socket is running on. When you create a client socket it still uses a port local to the JVM you're running the code in. Writing a standalone Java desktop app is most definately going to bind to it's own machine. I don't need to delegate anything to Tomcat itself, I need to know if I run a webapp and it binds and listens to a socket, which machine does it bind on? Some confusion here still, it's nothing to do with a webapp and entirely to do with the location of the code. Lastly, your statement about making it a webapp if http is not involved is because to centrally deploy an application is often served off http; I wanted to get into Java/webapps so I elected this route. You want to get into webapps, so you're build an app which has nothing to do with webapps? If they are standalone protocols (and they will be) to communicate between many clients to one (or a farm) of servers, why can't I launch it from http? Why would you? What does the servlet container offer that running the code independantly doesn't? You're not describing an application which uses the http connectors provided by Tomcat to operate, you're just using Tomcat as a launch wrapper for your app. p If opportunity doesn't knock, build a door.

Specifically, I would like to do something similar to the Netty Port Unification sample, but with HTTP AND XMPP protocols. Netty has the ability to inspect the incoming request and then get outta the way - adding the appropriate Channel for processing the request.

As a result, I was trying to determine if there is a way to create some type of Tomcat extension that where I could do the initial request routing and pass HTTP request on to the Tomcat's plumbing without running the built-in HTTP connector(s). You'd have to write your own connector implementation, or hack an existing one - in Tomcat 7.0 there's some work being done to consolidate the connector code, so you'd be wise to start there.

My problem is that during deployment of generated application Tomcat 7 reports OutOfMemory permgen error. I have experienced similar error on other application servers previously (e.g. Glassfish), but I could remove it then by changing server configuration. I have tried to change Tomcat 7 configuration as well - e.g. added JAVA_OPTS to Catalina configuration file, added environment variable JAVA_OPTS to my Microsoft Vista machine: -XX:PermSize=1024M -XX:MaxPermSize=1024M but permgen error occurs again and again (even after restarting computer and so on). I am using Tomcat 7.0.14. So - the question is - how to configure Tomcat 7 to increase the available memory? If I have tried to deploy my application on Tomcat 6 and for biggest part it gone well, namely, at the end it does not work, because Tomcat 6 is not for Servlet 3 (as I understand), but at least - there were not permgen errors. If you're using Tomcat inside Eclipse, you have to find the IDEs configuration mechanism - editing the Tomcat config won't help as it uses separate files. This is an IDE question, rather than a Tomcat one, it comes up sufficiently frequently that you'll probably find similar questions and relevant answers in the MyEclipse/Eclipse forums. p signature.asc Description: OpenPGP digital signature

Re: Feature request: fullstart command
On 15/06/2011 21:00, Francis GALIEGUE wrote: Tomcat has many abilities to deploy applications at run time (war, tree, context, you name it). However, when used in production, these abilities are used cautiously, if they are used at all. In many scenarios, Tomcat just starts, spends its life, and stops, with a defined set of webapps, and has no automatic deployment capabilities configured in at all. But the builtin startup scripts, and in fact, the Java code itself, lack at least two critical inputs for such scenarios: * Bootstrap will return (and therefore the startup scripts too) before webapps configured at startup time are deployed, and while bootstrapping is fast, deploying applications at startup can be very long; * even with a hackish way (watch the log file to account for complete server startup) in order to wait for webapps to be deployed, there is no status about these deployments at all (has this and that webapp been deployed successfully?). An application might report that it's started, even it hasn't finished initialising. Proposal: implement a fullstart command to Bootstrap which: * does NOT return until ALL webapps configured at start time are (attempted to be) deployed; * exits with a positive error code representing the number of webapps NOT correctly deployed (or 1 - I don't care as long as it's not 0, but please not -1, think WIFSIGNALED()). 'fullstart' is an odd name, people might start using it thinking that 'start' did not fully start the server.

Furthermore, if the application reports a successful start even though it is not completely initialized, i consider this an application fault, therefore not my concern. That makes no sense to me. As the person being responsible for the good behavior of applications in production, I expect webapps that I deploy to behave correctly, ie fail to deploy in the event of an initialization failure. That seems contradictory, but it's probably my misunderstanding. Tomcat won't provide me with this information, EXCEPT if I use the manager webapp (in text mode, of course) to deploy it, as I can parse the return message. Yes it will, using the same mechanism that the manager webapp uses; you can interact with Tomcat over JMX, the API gives you detailed information about applications. [...] 'fullstart' is an odd name, people might start using it thinking that 'start' did not fully start the server. Which is the case in this particular scenario!

Ok. p What I want is the return code to be the number of webapps NOT successfully deployed. But even that, I reckon, is not that good an idea: the JVM will return 1 in the event of an uncaught exception (or thrown from main()). So, 1+n, where n is the number of webapps not successfully deployed.

You can, right now, start blank Tomcat instances and deploy apps to them - managing the instance using JMX. What you can't do, is seamlessly transfer request processing from one running JVM to another - using Tomcat instances alone - because you can't exactly determine when one instance releases a port, enabling another to bind to it. This is why I referred to parallel deployment, which does permit seamless transfer to a new version of the app. Tomcat 7.0's parallel deployment sounds nice but it still doesn't solve the JNI and memory leak problems that haunt a single JVM architecture. Tomcat has some memory leak prevention capability (since 6.0.24) but JNI memory issues it can't prevent. What problems are you seeing? Parallel deployment is at once orthogonal to and the opposite of what you are requesting. Yeah, my fault, I misread what he was asking. See above. Please read the proposal and let me know what you think. What single management interface are you describing in your enhancement comments? The Tomcat manager webapp? It's trivial to run a manager in each JVM and use that for deployment. If you know that your webapp needs to do things such as register a shared library on startup, you can do one of two things: 1. Always bounce Tomcat directly instead of re-loading the webapp 2. Fix the webapp so it doesn't bomb on startup when the library is already loaded Tomcat provides the manager webapp and ant tasks to access it, plus a toolbox of scripts to start/stop/etc. Tomcat. Your needs seem to be fairly specific... why not just roll your own solution? Bouncing a JVM requires admin access to the local operating system, which you probably wouldn't want to give to a Tomcat application.

The Javadoc for javax.net.ssl.SSLContext.getInstance has a pointer to documentation for standard names (which takes you through several hops to) here: http://download.oracle.com/javase/6/docs/technotes/guides/security/StandardNames.html#SSLContext Those are the valid ssl protocol names you can choose.

Of course, support for a certain algorithm might not be available in your environment. It's best to find out what your JVM supports and use that.

That is pretty cool! Thanks for sharing that tip.
I did not find anything with tuckey urlrewrite, so I just wrote a
quick javax.servlet.Filter. It sanity checks: 1) no ?gzip=false
parameter (a la Tomcat's compression filter), and 2) Accept-Encoding:
{,x-}gzip in any of the headers, and 3) that new
File(request.getContextPath().substring(1) +
DEFAULT_GZIP_FILE_EXTENSION) exists.
You don't need to use the File object:
ServletContext.getResourceAsStream(/path/to/resource.ext)
which has the additional benefit that the container should prevent
access to resources outside of the context, as the path is relative to
the context.
p
On any FNFE / IOE, silently discard the exception and run the rest of
the chain; otherwise setting response header Content-Encoding: gzip
and copying the compressed version directly to the
response.outputStream before closing it.
It seems to work alright. My only concerns lay with: 1) malicious
contextPaths with ../../-style navigation, and 2) unpacked WARs which
contain the gzipped resource will take FNFE and not serve the
pre-compressed output as expected, and last and least 3) Accept-Range
is completely ignored.
For # 1: Is there some better way I should be obtaining the resource?
For # 2-3: Would it be better for me to just issue response.sendRedirect()?
