This looks like it should be possible using DOMConfigurator::configureAndWatch("./log4cxx.xml", 1000); which should check the log file every second to see if it has changed. If i change the logging level in the file and save it out it has no affect on my logs, however, if I restart it takes the new settings. I have attached to the running application and see no watchdog thread that would be checking if the file has been updated.

I have two different .exe that link the same log4cxx dll. I would like that both the exe uses the same configuration file and so write in the same log file. I was able to get this result, however I think that I did something wrong. I'm generating two .exe by building the attached cpp code, and both load the conf file in attachment. When I run the exes, it seems that everything works fine, and the log file example.log is fine. However I don't understand if my approach is fine. That is, how it is possible that the two processes don't access at the same time the log file generating by this way a conflict and corrupting it? I think that I should generate a logging exe that receives the messages from other processes and that then, from a single exe, I should access the log. Is there any suggestion? I'm a bit confused, any link/idea/feedback will be appreciated </pre> Giovanni Parodi 2012-11-29T14:33:32 http://comments.gmane.org/gmane.comp.apache.logging.log4cxx.user/3058 <pre>Has anyone seen any issues related to running C++ code inside a Java 7 JVM? Our application is a C++ DLL that is loaded from within a Java application. We just upgraded to Java 7, and are now seeing a strange problem with the console logging. There is a space inserted between every character that is output. Example from the initialization of the logging from an xml config file: l o g 4 c x x : r o o t l e v e l s e t t o I N F O l o g 4 c x x : C l a s s n a m e : [ o r g . a p a c h e . l o g 4 j . r o l l i n g . R o l l i n g F i l e A p p e n d e r ] This was not happening when we were running the same DLL within a Java 6 JVM. File based logging appears to be fine. Any help would be much appreciated.

All is working ok reading configuration file log4AI.properties. I have a process that loads this DLL and uses log4cxx too. This process is configured to read a properties file log4jSM.properties. When the process starts, the firsts traces are correctly logged into the correct file (log4SM.txt). After the process loads the DLL, all traces in the process are not going to the correct file and all goes to the logAI.txt (using log4AI.properties). Is log4cxx a singleton? could I have different instances of log4cxx in the same process?

I have successfuly build log4cxx in VS 2008 and linked log4cxx.lib and log4cxx.dll to my project. I have problem while my program is closing.

Unfortunately, log4cxx prints "&lt;null&gt;" for all the times when there is no NDC. Is there a pattern specifier that will make it just *be* null instead of printing "null"? If not, could someone direct me to the part of the code I can look for how to implement it?

One way I am considering doing it is configure a console appender for the log4cxx calls and then just redirect everything to the file. This doesn't get me a rollingfileappender though...unless... Can an appender append to an appender? What would you do?

For example, in RollingFileAppender &lt;lockingModel type="log4net.Appender.FileAppender+InterProcessLock" /&gt; or &lt;lockingModel type="log4net.Appender.FileAppender+MinimalLock" /&gt; It doesn't appear to be working for me. Maybe I have something configured incorrectly but I would like to know if the feature is even enabled before I waste too much time getting it to work. The objective is to permit viewing of an active log file (on Windows) using tools other than Notepad. WordPad and other editors are failing to open the file because they file is in use. Notepad allows the file to be viewed without any error. If this is not supported in Log4cxx 0.10.0 what are the alternatives? E.g. suggested code changes to log4cxx itself?

At first glance, that seems ok under the Apache 2 license, but when I inspected the dependencies of log4cxx I found that it depends on the Berkeley DB (libdb4.8) which is licensed under the Sleepycat License. This is a dual license that does not permit use in closed source applications unless we buy a commercial Berkley DB license from Oracle. I was a bit surprised by this finding, since it does not fit well with the permissive Apache 2 license. I tested log4cxx on Ubuntu 10.4, Debian package liblog4cxx10 version 0.10.0-1.1build1, and looked for dependencies with: $ ldd /usr/lib/liblog4cxx.so.10 linux-gate.so.1 =&gt; (0x00228000) libaprutil-1.so.0 =&gt; /usr/lib/libaprutil-1.so.0 (0x00a0f000) libdb-4.8.so =&gt; /usr/lib/libdb-4.8.so (0x00229000) libapr-1.so.0 =&gt; /usr/lib/libapr-1.so.0 (0x00f5e000) </pre> Johnny Njåstad 2012-03-19T09:49:55 http://comments.gmane.org/gmane.comp.apache.logging.log4cxx.user/3017 <pre> I am out of the office until 02/27/2012.
