Hello! i face an exception and i dont know how to solve the problem which
produces this exception. The app is using JTA and in Glassfish i configured a
datasource which i use in my persistence config for JPA and as datasource in
an process engine. After i finish a task using the process engine API the
data of the task is flushed to the datasource and it gets persisted
correctly. From what i can see by debugging is that the
JTATransactionInterceptor does not see an active transaction and creates a
new one using transactionManager.begin(), transactionManager being a
com.sun.enterprise.transaction.TransactionManagerHelper instance. The real
problem is that this exception only happens occasionally, thats why i can not
figure out whats going on. Maybe anybody has an idea what the exception
means? As i can not figure out whats missing when the problem occurs. Thanks,
