WS-RM's RMTxStore's does not recover stored sequences after restart
-------------------------------------------------------------------
Key: CXF-3114
URL: https://issues.apache.org/jira/browse/CXF-3114
Project: CXF
Issue Type: Bug
Environment: CXF 2.2.11 with Derby 10.6.2.1
Reporter: Aki Yoshida
When WS-RM's derby storage is activated, the sequence data are persisted in the
database.
However, these sequence data are not loaded from the database when the WS-RM
component is restarted.
This problem appears to be caused by the init method of the persistence class
org.apache.cxf.ws.rm.persistence.jdbc.RMTxStore which leaves an uncommitted
transaction to the relevant tables open. Consequently, the next select
statement that loads the persisted sequence data is not seeing the content.
The original source code fragment of this method looks like this:
{code}
try {
connection.setAutoCommit(false);
createTables();
} catch (SQLException ex) {
LogUtils.log(LOG, Level.SEVERE, "CONNECT_EXC", ex);
SQLException se = ex;
while (se.getNextException() != null) {
se = se.getNextException();
LogUtils.log(LOG, Level.SEVERE, "CONNECT_EXC", se);
}
throw new RMStoreException(ex);
}
{code}
The suggested change would be as follows:
{code}
try {
connection.setAutoCommit(true);
createTables();
} catch (SQLException ex) {
LogUtils.log(LOG, Level.SEVERE, "CONNECT_EXC", ex);
SQLException se = ex;
while (se.getNextException() != null) {
se = se.getNextException();
LogUtils.log(LOG, Level.SEVERE, "CONNECT_EXC", se);
}
throw new RMStoreException(ex);
} finally {
try {
connection.setAutoCommit(false);
} catch (SQLException ex) {
LogUtils.log(LOG, Level.SEVERE, "CONNECT_EXC", ex);
throw new RMStoreException(ex);
}
}
{code}
In the above code, the setAutoCommit(true) statement could be omitted if we
simply want to rely on the default autoCommit mode.
In any case, the suggested code makes sure that the subsequence statement is
correctly executed.
