Hi Friends, Problem: I've tried many times to configure apache-log4j-extras-1.0 with apache-log4j-1.2.16, but it is still failing to load classes from configure apache-log4j-extras-1.0 JAR file. What I want to do: Actually I want to do time based log rotation the my application specific log files.

Hi Friends,


Problem:
I've tried many times to configure apache-log4j-extras-1.0 with apache-log4j-1.2.16, but it is still failing to load classes from configure apache-log4j-extras-1.0 JAR file.


What I want to do:


Actually I want to do time based log rotation the my application specific log files. I could able to configure using 'net.cp.ps.sdk.util.log.DailyRollingFileAppender' class, but few problems are reported on Apache site for this class.


Solution I can think of:


So, I have to look for another option for 'net.cp.ps.sdk.util.log.DailyRollingFileAppender' class, and I found 'org.apache.log4j.rolling.RollingFileAppender' class and can use 'org.apache.log4j.rolling.TimeBasedRollingPolicy' in that.


Steps I performed so far:


1. Downloaded apache-log4j-extras-1.0 with apache-log4j-1.2.16 JAR files from web.


2. Renamed apache-log4j-1.2.16.jar to simple 'log4j.jar'.


3. Copied apache-log4j-extras-1.0.jar in ~/WEB-INF/lib directory, where my old log4j is present.


4. Extracted new log4j.jar (1.2.16).
5. Edited the pom.xml file from new 'log4j.jar' to include 'apache-log4j-extras-1.0'. Steps are described here:


6. Created jar file again, after editing pom.xml.


7. Then I added following configuration block, in my application specific log-conf.xml (present in ~/WEB-INF/etc/):





WEB-INF/log-files/access.log



WEB-INF/log-files/access.log.%d{yyyy-MM-dd}.log








but, still I am getting following exception:

7202 [main] WARN net.cp.ps.sdk.server.ServerConfig - thread[main] Unable to parse invite request mappings: [The XPath='invite-requests/invite-mapping' does not exist]


7214 [main] WARN net.cp.ps.sdk.server.ServerConfig - thread[main] Unable to parse known profiles request mappings: [The XPath='known-profiles-requests/known-profiles-mapping' does not exist]


8114 [main] ERROR net.cp.ps.sdk.server.ServerConfig - thread[main] Missing configuration: couldn't find value for /ps-conf/regex-whitespace-keyword


log4j:ERROR Could not create an Appender. Reported error follows.


java.lang.ClassNotFoundException:

Can someone please help me with this, what's going wrong?



Thanks in advance.
