Rsync through java program - issues with remote connection failure
Hi Everybody,

I am running rsync through my java application.

The Java application will sync the files with remote machine. During our connection failure testing we noticed an issue running rsync through java program. The java application which is running at source side is not receiving any error message if there are any connection issues during the sync process.

Brief details about the test scenario:

1. We run the Java Program
2. The java program starts the rsync command and sync the large number of files from source to remote destination
3. During the sync process we run the ps -ef | grep rsync to check whether the processes are running or not at both(source and dest) side. Both side rsync processes are running.
4. We identify the rsync process id at target machine and kill the process with Kill -9 <pid>
5. The java code didn't receive any error message and didn't exit. It just hanged.
6. And also noticed that the rsync process is still running at source side and rsync process is also not printing any log message in the log file.

Note : If we run the rsync command directly (not through java program) , then everything is working fine. When we stop the rsync process at target the source process will be stopped.



Through perl its working fine. Not sure what the problem with java...!!!



I don't have any clues to debug this issue.
Please share your thoughts and pointer to debug.


execuse me if i confused you .


Thanks !!

schemagen

schemagen(1)						      General Commands Manual						      schemagen(1)

NAME

       schemagen - Java(TM) Architecture for XML Binding Schema Generator Specification Version: 2.0
       Reference Implementation (RI) Version: 2.0 ea3

   Launching schemagen
       The schema generator can be launched using the appropriate schemagen shell script in the bin directory for your platform.

       The current schema generator can process either Java source files or class files.

       We also provide an Ant task to run the schema generator - see the instructions for using schemagen with Ant.

	  For Solaris/Linux

		% path/to/jaxb/bin/schemagen.sh Foo.java Bar.java ...
		Note: Writing schema1.xsd

	  For WindowsNT/2000/XP

		> path	ojaxbinschemagen.bat Foo.java Bar.java ...
		Note: Writing schema1.xsd

       If your java sources/classes reference other classes, they must be accessable on your system CLASSPATH environment variable, or they need
       to be given to the tool by using the -classpath/-cp options. Otherwise you will see errors when generating your schema.

	  Command Line Options

	     Usage: schemagen [-options ...] <java files>

	     Options:
		 -d <path>	   :  Specify where to place processor and javac generated class files
		 -cp <path>	   :  Specify where to find user specified files
		 -classpath <path> :  Specify where to find user specified files
		 -help		   :  Display this usage message

   Generated Resource Files
       The current schema generator simply creates a schema file for each namespace referenced in your Java classes. There is no way to control
       the name of the generated schema files at this time. For that purpose, use the schema generator ant task.
