Hallo,
Normally this code sequence is working fine.
This works with other databases / jdbc drivers like Cach�Jdbc, instantdb
jdbc ... that's why we
haven't got any idea...
System.out.println---------->Connection.isClosed() = true
ResultSetMetaData tRsmd = tResultSet.getMetaData();
int tCols = rsmd.getColumnCount();
The ResultSet object still exists here:
System.out.println---------->ResultsetMetaData
com.sap.dbtech.jdbc.ResultSetMetaDataSapDB@3f7281
System.out.println---------->ResultsetMetaData.getColumnCount() = 25
System.out.println---------->Resultset
com.sap.dbtech.jdbc.ResultSetSapDB@76ab2f
the next step doing:
while(tResultSet.next()){
this error occurs:
com.sap.dbtech.jdbc.exceptions.ObjectIsClosedException: SAP DBTech
JDBC:Object is closed
at
com.sap.dbtech.jdbc.ConnectionSapDB.assertOpen(ConnectionSapDB.java:98)
at
com.sap.dbtech.jdbc.ConnectionSapDB.execute(ConnectionSapDB.java:289)

com.sap.dbtech.jdbc.ConnectionSapDB.execute(ConnectionSapDB.java:272)

com.sap.dbtech.jdbc.ResultSetSapDB.fetchRelativePacket(ResultSetSapDB.java:577)
at
com.sap.dbtech.jdbc.ResultSetSapDB.relative(ResultSetSapDB.java:1549)
at
com.sap.dbtech.jdbc.ResultSetSapDB.next(ResultSetSapDB.java:1475)
...
The connection is closed before the resultset is read out. Do we need to
have an open connection?
Using other databases there wasn't this error.
Regards
Jens Panse
