What is the name of your web application? If it is "test" then the
"test\path" page is handled by the ROOT webapp. The "\" is not a
separator. It is just a character.
If you do not have ROOT webapp, then an attempt to access it will
return a zero-length response, but with correct HTTP response code and
reason phrase.

Problem with URL mapping
Hello all
I have problem with URL mappings with embedded tomcat 7
I whant to handle all requests to my applications. I added filter with
mapping /* for my application with context path "/"
FilterMap errorFilter = new FilterMap();
errorFilter.setFilterName("errors-filter");
errorFilter.addURLPattern("/*");
ctx.addFilterMap(errorFilter);
This works fine in most cases except the cases when "\" character is in
the request URL.
For examle
localhost:/test/path handled correctly, but
localhost:/test\path is not handled and server just returns
blank page
Any ideas?
Kind regards,
Sergey Mashkov

The Connectors handle only the HTTP/HTTPS/AJP requests/responses that go between the browser and Tomcat. If your application talks to anything else, then the timeouts have to be set there (in whatever your application is using to do that). Any timeouts (or any other parameter) set at the Tomcat Connector level will not have any effect here. Thanks,Intially i was in doubt that we can set request timeout at tomcat connector level as well.

Thanks, that explains it: as I wrote before, the abstract DelegatingResultSet methods in Tomcat 6.0.30 (resp. 7.0.27) are those marked Java 1.6 (resp. 1.7). Now, opening the class file in an hex editor, I can see that Tomcat 6.0 (resp. 7.0) was indeed compiled against Java 1.5 (resp. 1.6). So the problem stems from mixing Tomcat and JDBC driver classes that were compiled against different versions of Java, correct? -- O.L. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

While doing some profiling with Java VisualVM I have noticed that a lot of object (java.util.TreeMap$Entry) are created even when there is no traffic; they don't represent a memory leak because a garbage collection removes them all, but the still grow at a very high pace; they seem to be generated by JMX support in Tomcat.

AprLifecycleListener initialization issue
Hi , i'm new in this mailing list, i've started recently to integrate
tomcat in some of my applications ( i found a lot easyer to manage
tomcat inside a big servlet than viceversa), as early adopted java
developer i hope to help a bit in tomcat development when i become a bit
more expert, at this moment my tomcat integration it's stuck with the
AprLifecycleListener class,
i've compiled, installed apr ,jni, ssl and so fort documentation is a
bit tricky on that... expecially for path+external variables handlings
and compiling configurations,
i really hope to have time to build a guidelines for everything about
that...
...anyway i'll go to explain my issue :
public class AprLifecycleListener
it's a class which load jni component and check for apr existance and
versionm,
at first request it call :
private static void init()
then set a boolean private and unaccessible variable which avoid
successive calls
if (aprInitialized) {
return;
}
my problem is that this class seems to not recognize apr in my
computer.. i don't know exactly when this is called, anyway if i
overload this class and force to call the init() again within my
overloaded class it works...
i don't have a ready to test class , it will take some time to produce,
but if really needed i'll do..
anyway this is a test case i've done..
this (with my overloaded apr-Loader class ):
public static void main(String[] args) throws InterruptedException {
VarsTrackingHttpServer varsTrackingHttpServer = new
VarsTrackingHttpServer();
//System.out.println("ORIGINAL APR AVAILABLE? " +
AprLifecycleListener.isAprAvailable());
System.out.println("OVERLOADED APR CLASS AVAILABLE?" +
testAprLifecycleListener.isAprAvailable());
varsTrackingHttpServer.start();
Thread.sleep(150);
varsTrackingHttpServer.stop();
varsTrackingHttpServer.waitStopped(100);
}
- produce this :
init()__ STARTED
init()__ 1

- and if i call the standard class (it will fail to
load apr even if i call twice, because the boolean "initialized" avoid
successive calls) than i call my overloaded class ( it will load apr
correctly) , than also the original class recognize apr as loaded!
(HERE DOWN THE EXAMPLE..) so what's the trick? seems that the
AprLifecycleListener class is being called in a moment when apr is not
available and then there is no possibility to re-call it??
finally this :
public static void main(String[] args) throws InterruptedException {
VarsTrackingHttpServer varsTrackingHttpServer = new
VarsTrackingHttpServer();
System.out.println("ORIGINAL APR AVAILABLE? " +
AprLifecycleListener.isAprAvailable());
System.out.println("OVERLOADED APR CLASS AVAILABLE?" +
testAprLifecycleListener.isAprAvailable());
System.out.println("ORIGINAL APR AVAILABLE? " +
AprLifecycleListener.isAprAvailable());
varsTrackingHttpServer.start();
Thread.sleep(150);
varsTrackingHttpServer.stop();
varsTrackingHttpServer.waitStopped(100);
}
PRODUCE :
