PSQLException: current transaction is aborted, commands ignored until end of transaction block

Question

I am seeing the following (truncated) stacktrace in the server.log file of JBoss 7.1.1 Final:

Caused by: org.postgresql.util.PSQLException: 
ERROR: current t         


        

Answer 1

The reason for this error is that there are other database before the wrong operation led to the current database operation can not be carried out（i use google translation to translate my chinese to english）
