Failed to connect to remote VM. Connection refused.


Encountered this error while trying to debug my project.
IDE: Eclipse
Server: Jboss
Error:  Failed to connect to remote VM. Connection refused.

Reason:

When we install JBoss server the debug option is disabled by default.

Solution:

Go to ur jboss directory “<directory>/bin” and edit run.bat.
Search for:
rem set JAVA_OPTS = -Xdebug -Xrunjdwp:transport=dt_socket, address=8787, server=y, suspend=y %JAVA_OPTS%

‘rem’ in above statement shows that this line is comments. So remove ‘rem’ and set suspend=n.

How databasechangeloglock and databasechangelog table used by liquibase?

Liquibase takes care of executing the query on the database while maintaining the list of queries executed and also maintaining the locks over the tables simultaneously.
