Java interface

All cmlog Java classes are organized into a package all cmlog. Java interface for logging clients are organized into a single Java class called Client. The html version of the Java API document can be found inside the cmlog Java distribution or can be generated from Java source code using the javadoc utility. All configuration information and status code are organized in a single Java class Config.java. The following lists some of the important parameters:

• • CMLOG_PORT = 8900
  • CMLOG_CLNT_PORT= 8909
  • CMLOG_CLNT_PIPE = "/tmp/cmlog/''
  • CMLOG_CLNT_PIPE_PREFIX = "cmlog_"
  • CMLOG_SUCCESS = 0
  • CMLOG_ERROR = -1
  • ......status codes......
  • PROTOCOL_MAJOR_VERSION = 2

These parameters have to be consistent with those defined in the C/C++ header files such as CMLOG/Common/cmlogConfig.h (cmlogProtocol.h).
