JDBC, PrepareStatement and TimeStamp problem

I get an error with the timestamps when running the following code:
(Varibbles currentTrainStart and stop are GregorianCalendars)
String tableName = "\"AdultData\"";

String tempSql = "SELECT
\"Age\",\"Gender\",\"PrimaryLanguage\",\"TimeOfDay\",\"DayOfWeek\",\"ChiefComplaint\",\"BodyFluidIso\",\"RespIso\",\"Acuity\",\"Consult\",\"Labs\",\"Radiology\",";
tempSql+= "\"EKG\",\"MOA\",\"Admitted\" FROM ? ";
tempSql +="WHERE \"DATE_ADMITTED\">= ? AND
\"DATE_ADMITTED\"< ? ;";
query = conn.prepareStatement(tempSql);

query.setString(1, tableName);
Timestamp startTrain = new
Timestamp(currentTrainStart.getTimeInMillis());
query.setTimestamp(2,startTrain);
Timestamp stopTrain = new Timestamp(stop.getTimeInMillis());
query.setTimestamp(3, stopTrain);

System.out.println(query.toString());

query.executeQuery();
// query.clearParameters();

When I execute the following code I get the error:

java.sql.SQLException: ERROR: syntax error at or near "$1"

org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse(QueryExecutorImpl.java:1482)

at TemporalDataSetCreator.getNextDataSet(TemporalDataSetCreator.java:180)
at SequentialBNTest.main(SequentialBNTest.java:31)

After initiating the places holders in the prepared statement and call
toString() I get the following line going to the DB:

SELECT
"Age","Gender","PrimaryLanguage","TimeOfDay","DayOfWeek","ChiefComplaint","BodyFluidIso","RespIso","Acuity","Consult","Labs","Radiology","EKG","MOA","Admitted"
FROM "AdultData" WHERE "DATE_ADMITTED">= 2004-05-10 00:00:00.000000+0100
AND "DATE_ADMITTED"< 2004-05-31 00:00:00.000000+0100

Which if I put in pgAdmin III and add single quotes around the
Timestamps if runs fine. If I add \' around the ? in the prepared
statement it gives the ? to the DB and throws and error. What am I doing
wrong?

Thanks,
