this is an example
private static org.apache.juli.logging.Log log=
org.apache.juli.logging.LogFactory.getLog(
IntrospectionUtils.class );
as soon as that statement is executed, the logging gets initialized.
as you can see, it is a static field, so when you run Tomcat embedded,
before any classes are loaded (that would lead to initialization), you
must set those properties.
as you can see, the Embedded class also does this
public class Embedded extends StandardService implements Lifecycle {
private static Log log = LogFactory.getLog(Embedded.class);
meaning, if you have references to embedded in your public static void
main(String[] args) class, then it's too late to set the system
properties at that time

Hi Filip... maybe you can help me here...
Its actually not that I'm starting TC then doing the
System.setProperty I do props first.
I'm using the 6.0.13 code and when I search it for
java.util.logging.manager ... ie to see where it actualy reads this
property, I can find it anywhere.
For example in ClassLoaderLogManager... there is the this line for getting
the prop to the config file...
String configFileStr =
System.getProperty(java.util.logging.config.file);
BUT there seems to be no similar line to read this property...
System.setProperty(java.util.logging.manager,
org.apache.juli.ClassLoaderLogManager);
So the problem seems to be that nowhere does the TC code read this
property??
Its like I got a missing class... or theres a precompiled class that must
be included I dont understand this???
I think this is the problem... guessing here
This java.util.logging.manager is part of Java, not Tomcat...
So on the command line as Java starts it inits this...
So I think even if this property is set as the 1st line in your code, its
too late.
The app has started and so Command line options are missed.
TC then calls this Logger.getLogger... and finds no
ClassLoaderLogManager set.
The console must be set in TC somewhere because that still works... it seems
that when
ClassLoaderLogManager is not set, no log files will be recorded...
I think one has to tell java.util.logging.Logger to use
ClassLoaderLogManager directly in the embedded program...
Hopefully a Guru helps the original user here...
... and as I said before, all I did in the end was trap the console output,
display it in the app and if I want a LOG file, I'll just write it out to
one... it just gets too complicated, trying to figure out how TC redirects
streams, and manages log options in an embedded app...
If it does work then it also redirects standard output, so if you get the
logs going then I think you can kiss displaying messages directly to the
user, through the app goodbye... I dont know... I just avoid TC's logging.
Good Luck Thats my best shot... I officially give up ;)

Ah... I think I'm onto it...
Have a look at this link...
http://www.vsj.co.uk/java/display.asp?id=319
Have a look at this section
// set default logger and realm
FileLogger fileLog = new FileLogger();
fileLog.setDirectory(.);
fileLog.setPrefix(vsjMbedTC5);
fileLog.setSuffix(.log);
fileLog.setTimestamp(true);
mbedTC5.setLogger(fileLog);
See the guy is setting up a simple logger... which I think does mean the
System.setProperty(java.util.logging.manager,
org.apache.juli.ClassLoaderLogManager);
property is in fact useless in an embedded app

Re: Second webapp lib folder
Russ,
1. I think that configuring /WEB-INF/lib2 is not possible. The spec
has no provision for it.
2. You may place all these jars into shared jars folder in tomcat configuration,
and exclude them from your war.
In tomcat 5.5.x, the place is ${catalina.base}/shared/lib/
See
http://tomcat.apache.org/tomcat-5.5-doc/class-loader-howto.html
3. If you really need it, the location of the /shared/lib folder can
be configured.
E.g. it can be split into several ones, like ${catalina.base}/common/
is split into
several folders.
You do this by modifying classloaders configuration in
catalina.properties file.
Best regards,
Konstantin Kolinko

So on the command line as Java starts it inits this... So I think even if this property is set as the 1st line in your code, its too late. All the above is correct. See the API doc for java.util.logging.LogManager. The static initializer for that class uses either an instanced of itself or an instance of the class named on the aforementioned system property. Thus, you need to set java.util.logging.manager prior to initializing the JVM. Possible solutions: 1) Make sure the system property is set on the command line for the launcher. 2) Write your own launcher that sets the property then initializes a JVM via JNI (thereby sacrificing platform independence). 3) Start the embedded Tomcat in a child JVM, so its system properties can be set beforehand.

Re: Copying large files around
Yes. It has AT (command line) and a scheduler (GUI). You can do a batch file and set it to run at a certain time, day and frequency. I had a client that I setup the dhcp service to stop, copy the database over to a backup directory and then restart the service in a batch file. Then I called it every night before the tape backup ran. AT is a lot lighter than Scheduler so using it is preferable.

Re: Does mod_jk copy memory b/w apache and tomcat (using linux, ajp13 worker)?
Apache httpd and Tomcat do not share any memory, so there is not any explicit memory-copying going on. How do they share data? For example, when Tomcat creates an HTTP response containing 50k of HTML, I assume that data exists in Tomcat's memory space. How does that data move over to apache's so it can respond to the HTTP request. If the apache and tomcat process don't use any shared buffers (in linux) wouldn't that mean the data is copied form tomcat's memory space to apache's? If the two processes are on the same machine, and are using the localhost NIC, then UNIX is usually smart enough to do memory copies instead of doing all the TCP/IP stuff necessary to send the data to a remote host. I guess that actually answers my question: the data is (probably) copied between tomcat's memory space and apache's (under ajp13). However, would there be room here for an optimization that uses a shared_buffer to communicate b/w apache tomcat on the same machine? This could reduce process to process data copying. However, from my understanding that can also be achieved through the jni mod_jk worker. Do you know of any good documentation on that worker? I noticed that references such as in this page http://tomcat.apache.org/connectors-doc/generic_howto/workers.html use tomcat version 3.3 as a tomcat instance inside apache's mem space. Are there limitations in doing this with newer tomcat's? Again.. my apologies for not trying this out first.. I'm only asking because there seems to be very little in-process documentation out there (that doesn't reference very old tomcat versions). thanks, moran - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

No, database mirroring isn't an option for this particular case; it's rather cost-sensitive, and the customer decided that the extra reliability wasn't worth the extra cost. This database has a backup procedure that is specifically designed to handle transactions that occur during the backup without causing trouble. Plus, the full backup is done during the middle of the night when there is normally nothing going on (there is only activity about 18 hours per day in this app). The other backups during the day are incrementals.

Tomcat 5.5.25, SSL and invalid keystore format
Hello, I am trying to setup SSL in my Tomcat 5.5.25 (on Debian Linux) and thus downloaded a binary version of Tomcat from the Tomcat website. Now I tried to create a keystore: # keytool -genkey -v -keyalg RSA The server.xml is as follows: Connector port=8443 maxHttpHeaderSize=8192 maxThreads=150 minSpareThreads=25 maxSpareThreads=75 enableLookups=false disableUploadTimeout=true acceptCount=100 scheme=https secure=true clientAuth=false sslProtocol=TLS / The error message in the log I am getting is: SEVERE: Catalina.start: LifecycleException: service.getName(): Catalina; Protocol handler start failed: java.io.IOException: Invalid keystore format at org.apache.catalina.connector.Connector.start(Connector.java:1097) at org.apache.catalina.core.StandardService.start(StandardService.java:457) at org.apache.catalina.core.StandardServer.start(StandardServer.java:700) at org.apache.catalina.startup.Catalina.start(Catalina.java:552) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:295) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:433) What is causing this problem? Why is the keystore not valid? Has this to do with the APR or something? How would I need to create a keystore then to make it work in Tomcat? I also tried to specify the keystore location and name but that doesn't change anything...any ideas? Thank you.

Re: embedded Tomcat (5.5.23) application logging (java.util.logging)
I really appreciate the timeliness of all the responses and the theory behind how and when logging is configured and initialized has been explained really well. However I'm not so sure I have explained where I actually am very well. I have been able to configure Java logging via the command line and within the app I wrote which utilizes embedded Tomcat and get desired output. The output I am not getting is from the either of the two web applications (which are registered wars). The part I am not following is if I am getting output from the logging (which utilizes java.util.logging ) in the application itself and the hosted web applications are also using java.util.logging, why am I not getting output from these? If the configuration is ignored because the JVM has already been initialized, I would think the configuration set via the Java Control Panel would be utilized. I suspect there's something simple I am not doing when I register these apps. All the above is correct. See the API doc for java.util.logging.LogManager . The static initializer for that class uses either an instanced of itself or an instance of the class named on the aforementioned system property. Thus, you need to set java.util.logging.manager prior to initializing the JVM.
RE: Copying large files around
From: David Kerber [mailto:[EMAIL PROTECTED] What is the most efficient (=fastest) way of copying large ( 1GB [yes, that's a Giga]) files around the network in java when running under tomcat 5.5.x? Do I use a FileInputStream and FileOutputStream with a large byte[] array? Or what? If you *definitely* want efficient, and you're on Windows, then: - Do not use Java, use OS-level tools; - Run the tools on the receiving machine, not the sending machine. You don't have to worry about differences in buffer sizes between the network and whatever chunking you're using on the Java file copy, and I'm pretty sure I've seen copy pre-allocate the entire file space when the target file is local (because it knows it's copying a source file and it knows it has exclusive access, so the size doesn't change). I've never seen that behaviour when copy is running to a network share. The easiest way of doing this on Windows is via the AT command: write yourself an at that runs a couple of minutes in the future (use Java to look up the time :-) ), similar to: at \\targetserver 21:02 c:\jobs\copyFromLive.bat Ugly as sin, but it works and it's fast. - Peter - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Copying large files around
Seconding Peter's comments: It is extremely unlikely that you can beat the Windows tools for this sort of thing (been there, done that). Also, if your webapp isn't physically on one or the other boxes (as Peter said, preferably the reciever), then you are pretty much guaranteed to lose. That being said, if you insist on using Java, then use a MappedByteBuffer on the source, and either a transferTo or TransferFrom to send it to the to. On Windows, this makes an order of magnitude difference for 1GB+ files.
