Nested exception is: 

while i googling common solution from

Are these instances running in a single machine? .. like, are those running in an app server, where it is pointed to a single CARBON_HOME? .. if so, the "transaction.properties" file have to be removed from /repository/lib and should be put into each WARs classpath location. And each "transaction.properties" file has to be edited to change the log file location. This error comes when more that one instance is trying to access the same transaction log file of Atomikos, or there's also a chance that the earlier JVM shutdown was not done properly and the lock file wasn't released. In that case, you simply have to remove the log file at /repository/data/tmlog.lck file and restart the server.

i follow this advise . remove property file from tomcat/common/lib to my war's classpath . changed directory accordingly above mentioned. i also check for tmlog file but it does not exist on the server.

but nothing works . still the error occurs.

if you see at atomikos page

The lock file in question is created to protect the transaction logs against accidental duplicate startups. Otherwise, the logs could get corrupted when two instances of the same transaction manager are recovering on the same data. Normally, it suffices to follow the hints and then delete the lock file manually if needed. 

it just states follow the hints , but where is the hint ??

please help me to re solve it.

atomikos is the open source,

i checked the source code and found the below lines which is throwing exception

if ( enableRecovery ) {
             //ISSUE 10077: don't complain about lock file if no logging
            try {
                lockfilestream_ = new FileOutputStream ( lockfile_ );
                lock_ = lockfilestream_.getChannel().tryLock();
                lockfile_.deleteOnExit();
            } catch ( OverlappingFileLockException failedToGetLock ) {
                //happens on windows
                lock_ = null;
            } catch ( IOException failedToGetLock ) {
                //happens on windows
                lock_ = null;
            }
            if ( lock_ == null ) {
                 System.err.println ( "ERROR: the specified log seems to be "
                        + "in use already. Make sure that no other instance is "
                        + "running, or kill any pending process if needed." );
                throw new RuntimeException ( "Log already in use?" );
            }
        }

i have already set debugging to false in jta.properties com.atomikos.icatch.enable_logging=false and restart my server but still the same error.

Thank You Mihir Parekh
