You're not showing enough code. Can you guarantee that no other thread
either got and closed the statement, or closed the connection that generated
the statement?

Hi Ramesh,
Thanks for those clues.
You may want to try testing the boolean value of
cs.getConnection().isClosed()
after each of the Java statements involving cs, to see where the
connection is being lost i.e.
cs = mCreateTaskNoteCall.getCall();
Connection conn = cs.getConnection();
if (conn == null)
System.err.println(&conn is null after getCall&);
if (conn.isClosed())
System.err.println(&conn is closed after getCall&);
cs.setLong
(1, taskID);
if (conn.isClosed())
System.err.println(&conn is closed after setLong #1&);
cs.setString(2, noteText);
if (conn.isClosed())
System.err.println(&conn is closed after setString #2&);
and so forth.
I guess it depends on your JDBC driver whether any of the calls
before cs.execute() actually involve network traffic with the
server, but it may help to narrow down where the connection is
being dropped by the server.
What type of database server is your code talking to, anyway?
Hope this helps.

I am getting this Closed Statement exception intermittently.
I am using prepared statement for multiple inserts in a loop.
Using Weblogic 7.4 App server & Oracle 9i db.
Here is the sample code i am using
Connection
PreparedStatement ps =
int result = 0;
con = getConnection();
con.setAutoCommit(false);
ps = con.prepareStatement(&INSERT INTO
AUDIT(USER_ID,FIRST_NAME,LAST_NAME,CODE) VALUES(?,?,?,?)&);
if(eCodes != null) {
for(int i=0;i & eCodes.i++) {
ps.setString(1,user.getUserId());
ps.setString(2,user.getFirstName());
ps.setString(3,user.getLastName());
ps.setString(5,eCodes[i].getCode());
result = executeUpdate(ps);
} catch(SQLException e) {
// here the Closed Statement exception is coming
logger.error(&[logUserActivity] error : &+ e.toString());
} finally {
// if (ps != null)
// closeStatement(ps);
} catch(SQLException e) {
logger.error(&[logUserActivity] error : &+ e.toString());
} finally {
if (ps != null)
closeStatement(ps);
if (con != null)
closeConnection(con);
Am I doing any mistake here ?

Remove the finally block in the loop.
You must not close the PS as long
as you use it.
I prefer a proper nesting of try finally for such
scenarios:
if ( eCodes == null )
Connection con = getConnection();
PreparedStatement ps = con.prepareStatement( &INSERT INTO
AUDIT(USER_ID,FIRST_NAME,LAST_NAME,CODE) VALUES(?,?,?,?)& );
for ( int i = 0; i & eCodes. i++ ) {
ps.setString( 1, user.getUserId() );
ps.setString( 2, user.getFirstName() );
ps.setString( 3, user.getLastName() );
ps.setString( 5, eCodes[i].getCode() );
result = executeUpdate( ps );
} catch ( SQLException e ) {
here the Closed Statement exception is coming
logger.error( &[logUserActivity] error : & +
e.toString() );
closeStatement( ps );
closeConnection(con);

The error refers to the &VisitLength& field which is a &time& data
type in the database. In the MySQL documentation, it says that
00:00:00 is allowable for time (/doc/refman/4.1/

So my question is, why is this error coming up if it's an allowable
value? And is there anything I can do?

one way is to store the values as raw ints or longs as far as SQL is

I am back for some more much need advice and assistance!
am creating a database for the first time.
I am changing some programs I
recently wrote to work with this database that have to do with Salesmen.
am getting the below error when I compile CreateDatabase.java.
In that I am
creating the database SalesDatabase and then creating 5 tables (Users, SType,
Salesman, Sales, Product).
The first thing I do is create those tables and
then insert informtion into the SType table and Product table.
SType is the
SalesType of a salesman, meaning Entry, Junior or Senior that also has the
bonus in there as another field (.05, .10, .15) and then product has product
1, 2, 3, 4, and 5 with the corresponding price of each.
After I do this I
need to read in a text file (SalesInformation.txt) and calculate the sales
based on the information in the database.
So here are my questions:
(1) What is the below error telling me, have I not set the database up
correctly?
(2) Am I on the right track with what I have below, should I be reading the
text file as I am or should I change it to be its own method (anything you
tell me would be apprecaited!!)?
(3) Also, other than it not compiling...lol...I am unsure of the salestype
part with element 6 on line 124.
I read in ENTRY, JUNIOR or SENIOR from the
salesinformation.txt file so how do I relate that with retrieving the bonus
number from the database?
Ok, I think that is enough questions for now.

You can find the text behind any error message by typing finderr
&msgno& at the command prompt. The ones you're getting come out as:
Identifier length exceeds the maximum allowed by this version
of the server.
A name in the statement exceeds the maximum length. In 7.x, 8.x, and
versions of the database server, the maximum length for identifiers in
statements is 18 characters. In 9.2 and later versions of the database
server, the maximum length for identifiers in SQL statements is 128
characters.
Check the length of the names and whether a typographical error caused
names to run together.
Too many or too few host variables given.
The number of host variables that you named in the INTO clause of this
statement does not match the number of &?& place holders that you
into the statement. Locate the text of the statement (in a PREPARE or
DECLARE statement), and verify the number of place holders. Then
the list in the INTO clause to see which item is incorrect.

Whether and how you import classes has exactly zero effect at runtime.
(with or without wildcards) are only a kind of abbreviation provided by the
compiler to save us the effort of typing in fully-qualified type names every
In theory explicit importing should make compilation faster -- by a very tiny

So the question comes down to how to write your code for maximum clarity.

(rather than by a wildcard).

The cause for this is probably that the RBScanner classes depends on
another class which has changed. This can happen if you didn't perform
a full recompile of the sources.
