reg individual log files for each request

[Sumitha Arjunan <Su...@lntinfotech.com>]

Hi,

In our application, we have to write the logs into different log files based on the reference number in the file.

For example suppose my file FileSample.txt is having reference 1123 , then the log file name should be ref1123.txt and whenever it come across the same reference, it has to write into the same file.

If the subsequent request deals with some other reference(4456) number it has to write the logs into the ref4456.txt.

Please let me know how can I implement this functionality.

AW: reg individual log files for each request

[Stadelmann Josef <jo...@axa-winterthur.ch>]

We do the same.

 

In our web service we have long lasting sessions, that is to say each users session request ends at the same session thread related object, 

which an instance of a web service class.

 

Now the session context delivers the uniqe number, an id, and that object has a session logger, and the name of a unique session log file is given.

 

happy study

Josef

            }

        }

    }

}

 

 

So we are allowed to configure appenders, use it, and fine trim on a per object-base certain things like a file name.

Betreff: reg individual log files for each request

 

Hi,

 

In our application, we have to write the logs into different log files based on the reference number in the file.

 

For example suppose my file FileSample.txt is having reference 1123 , then the log file name should be ref1123.txt and whenever it come across the same reference, it has to write into the same file.

 

If the subsequent request deals with some other reference(4456) number it has to write the logs into the ref4456.txt.

 

Please let me know how can I implement this functionality.

 

Sumiarjun
