I am using XMLSocketAppender and have a problem using it.
I have a client listens on a port and prints logging messages. Seding
logging messages to client using XMLSocketAppender. Strangely, first
LOG4CXX_INFO from logging program is received properly at client (which
is waiting with accept system call) but not subsequent. I am pasting
config file, client file and actual program for reference. I searched
thru mailing lists, but similar problem was not faced by anyone before.
Config:
log4j.rootLogger=DEBUG, SOCK
log4j.appender.SOCK=org.apache.log4j.net.XMLSocketAppender
log4j.appender.SOCK.RemoteHost=10.232.15.31
log4j.appender.SOCK.Port=9000
log4j.appender.SOCK.LocationInfo=false
Actual program:
int main()
{
int result = EXIT_SUCCESS;
try
{
PropertyConfigurator::configure(LOG4CXX_FILE("socket.properties"));
LoggerPtr logger=Logger::getLogger("SOCK");
LOG4CXX_INFO(logger, "info message"); ---> this message
is received at remote machine
LOG4CXX_INFO(logger, "info message1"); ----> from here
on, no message is received
LOG4CXX_INFO(logger, "info message2");
LOG4CXX_INFO(logger, "info message3");
LOG4CXX_WARN(logger, "warn message");
LOG4CXX_ERROR(logger, "error message");
LOG4CXX_FATAL(logger, "fatal message");
}
catch(std::exception&)
{
result = EXIT_FAILURE;
}
return result;
}
Client program:
while(1){
sin_size = sizeof(struct sockaddr_in);
if((newsockfd = accept(sockfd, (struct sockaddr *)&their_addr,
(socklen_t*)(&sin_size))) == -1){
perror("accept");
}
n = read(newsockfd,buffer,255);
if (n < 0) perror("ERROR reading from socket");
cout<<buffer<<endl;
fputs(buffer,pFile);
}
Output:
45 if (n < 0) perror("ERROR reading from socket");
(gdb)
48 cout<<buffer<<endl;
(gdb)

The program is running. Exit anyway? (y or n) y
Thnx,
