Hello all,

I have trouble with executing PreparedStatements. Some select statements fail with the exception shown below.
It does no matter if the statements were executed from a session or a entity bean. Inserts and updates are working properly.
I could not find any reason why this exception comes up.
Any suggestions?

I'm using JBoss 2.4.3 with Tomcat 3.2.3 and Oracle 9i.



Thats what the code looks like:

ps is declared as PreparedStatment, result is declared as ResultSet and dbConn is declared as Connection

public void ejbLoad() {
AccountPK primaryKey = (AccountPK)context.getPrimaryKey();
ps = null;
result = null;

try {
ps = dbConn.prepareStatement(
"SELECT ACC_NR, " +
" ACCOUNT, " +
" KUNDE, " +
" INFO " +
" FROM TS_ACCOUNTS " +
" WHERE ACC_ID = ?");
ps.setInt(1, primaryKey.id);
result = ps.executeQuery();
if (result.next()) {
id = primaryKey.id;
accnr = result.getInt(1);
account = result.getString("account");
kunde = result.getString("kunde");
info = result.getString("info");
}
else {
throw new EJBException();
}
} catch (SQLException se) {throw new EJBException(se);}
finally {
try {
if (result != null) result.close();
if (ps != null) ps.close();
} catch (SQLException se) {se.printStackTrace();}
}
}
