Check the following path in your server:
If you are using NW04s: :\usr\sap\<InstanceName>\JC00\j2ee\cluster\server0\log\
If you are using CE: :\usr\sap\<InstanceName>\J00\j2ee\cluster\server0\log.
If you are using CE: [Log Viewing with the SAP MC|http://help.sap.com/saphelp_nwce10/helpdata/en/44/f71b59e38e2462e10000000a1553f7/content.htm]
