Logging on NW04

Question

Hi,
I'm trying to implement logging a Netweaver application.
The application must be backwards compatible with SP2. The SP2
logging works fine, but i can't get the Netweaver logging to
work even though.
Following are the steps i took (got this from sap.help.com)
http://help.sap.com/saphelp_nw04/helpdata/en/e2/f410409f088f5ce10000000a155106/frameset.htm
NetWeaver version:
Stack 10
Configuration of the Portal through visual admin:
=================================================
1. Navigate to Server->Services->LogConfigurator
2. Click the 'to Advance mode' tab
3. Click the 'Destinations' tab and clicked 'new' for a new Destination
  entered the following data:
  Name: FrameworkLog
  Type: FileLog
  Pattern: ./log/framework.log
  Limit: 500000
  Count: 5
  Severity: All
  Formatter: Anonymous[ListFormatter]
4. Created a Location by choosing the "Location" tab
  Name: framework.loger
  Min: all
  Max: all
  Severity: all
5. Assigned the Destination created in (3) to the new Location
Configuration in the logger.xml file:
=====================================
added the following to the logger.xml file:
the filename parameter is kept for backwards compatibility reasons.
<Server>
  <Logger name="framework.logger"
          loggerInterface="com.sapportals.portal.prt.logger.ILogger"
          isActive="true"
          locationName = "framework.logger"
          >
   <LoggerClass className="com.sapportals.portal.prt.logger.SimpleFileLogger" level="ALL">
      <param filename="logs/framework.logger.log" append="false"/>
   </LoggerClass>
  </Logger>
</Server>
Usage in source code:
=====================
static Location location = Location.getLocation("framework.logger");
location.debugT(xxx);
The problem is:
Even though I save everything in the Visual Administrator (after step 5) the assigned
destination disappears if you, say browse the logviewer and return to the Location.
All log messages are written to the defaultTrace.
I tried using a Category. Created a new Category in the Visual Admin and assigned the
Destination created in step 3.
The usage in the source code was
static Category category = Category.getCategory("framework.logger");
// then using the location attempted to write
category.info(location, "xxxxx");
Once again everything was written to defaultTrace. the one difference however,
was that a (empty) logfile was created and the Destination assigned to
the Category did not 'get lost'
any hints as to what i'm doing wrong would be greatly appreciated.
cheers

Hi Michael,
probably you didn't deactivate ForceSingleTraceFile, see https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/events/webinars/using logging and tracing on the sap web as java.pdf pages 12-17
Also see http://help.sap.com/saphelp_nw04/helpdata/en/e2/75a74046033913e10000000a155106/frameset.htm for portal specific statements.
Hope it helps
