StringIndexOutOfBoundsException while reading a field

Question

Hi! I'm using a postgres database with JDBC and when I try to read a timestamp field (defined as timestamp in the database), I got the exception:
java.lang.StringIndexOutOfBoundsException: String index out of range: 26
     at java.lang.String.charAt(String.java:444)
     at org.postgresql.jdbc2.ResultSet.toTimestamp(ResultSet.java:1653)
     at org.postgresql.jdbc2.ResultSet.getTimestamp(ResultSet.java:398)
     at org.postgresql.jdbc2.ResultSet.getTimestamp(ResultSet.java:617)
     at aplik.informat.handlers.data.ClassificationDataRetriever.getClassificationPeriods(ClassificationDataRetriever.java:209)
The code is very simple:
205          Date day =null;
206          while( rs.next() )
207          {
208               //Get the data from the database
209               day =rs.getTimestamp("validfrom");
Any ideas??

Hello,
You are trying to get the Timestamp object and
and storing in Date object which is not possible
because TimeStamp is the extension of Date class. so
try stroing in Timestamp then try to convert it into
string and get the value required from that Time stamp
string.I can see that you are enthusiastically trying to participate in the forums. However, a large number of your posts are either irrelevant to the original topic or simply wrong - like this one.
So please.
1. Read the post and all of the responses before replying.
2. Verify what you are saying.
To clear up the misconceptions in your post.
- The answer has nothing to to with what the problem was (the poster already pointed out what the problem was.)
- The getTimestamp() field returns an instance of java.sql.Timestamp. Timestamp is derived java.util.Date. In the above code that means that "Date day" must be a java.util.Date or the code would not have compiled. The code above is running thus is already is compiled. This is fundamental to the way java works and has nothing to do with JDBC.
- There are reasons for extracting non-string types from a database as strings. In general doing so with dates (timestamps) is a bad idea because they are always database dependent and even database instance dependent. So only when absolutely necessary should it be used.
