Java.sql.GeneralException caused by content ??

Question

Hello.
I have today been writing a small program to input a 200 pages file containing all my SMS messages from my phone to a MS access database.
The problem is, that the database only accepts about 20 og the messages, when i try to add the rest, i get a java.sql.generalexception..
This is the stacktrace:
java.sql.SQLException: General error
    at sun.jdbc.odbc.JdbcOdbc.createSQLException(JdbcOdbc.java:6987)
    at sun.jdbc.odbc.JdbcOdbc.standardError(JdbcOdbc.java:7115)
    at sun.jdbc.odbc.JdbcOdbc.SQLExecDirect(JdbcOdbc.java:3111)
    at sun.jdbc.odbc.JdbcOdbcStatement.execute(JdbcOdbcStatement.java:338)
    at sun.jdbc.odbc.JdbcOdbcStatement.executeUpdate(JdbcOdbcStatement.java:288)The fields in the db i try to input is the txt: "from" and "to",
the java.sql.Date: date
and the note: message
the primary key is th date field.
For eksample; this message goes in well eneugh to the database:
from: Anders
to:Jane
Date: 15-1-2005 (the representation in a real date - not millis (copyed from access))
message: Mange tak s :)
but the folowing does not:
From:     249
To:     Anders
Date:     1107504180000
Message: Kre kunde. Din TELMORE saldo er nu p -3,71 kr. Mvh. TELMORE
(the '' is because the program on my phone dosent support danish letters...)
How come the dbms don't take the second message when the first one went in fine ??
The code for inserting into the table comes here:
    public  boolean setMessage(String afsender, String modtager, java.sql.Date date, String besked) {
        boolean ok=false;
        try {
            Statement stm =con.createStatement();
            String s1 = "INSERT INTO BESKEDER " +
                    "VALUES ("+afsender.trim()+
                    "," +modtager.trim()+
                    "," +date+
                    ","+besked.trim()+
            stm.executeUpdate(s1);
            ok = true;
            stm.close();
        } catch (Exception se) {
            System.out.println("ERR :");
            se.printStackTrace();
        return ok;
    }-- and i naturaly opens and closes the db stream properly..
Finaly, i have had the plesure that the program results in a crash in the HotSpot Virtual Machine:
# An unexpected error has been detected by HotSpot Virtual Machine:
#  EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x7c901010, pid=2632, tid=3428

The problem is, that the database only accepts about 20
og the messages, when i try to add the rest, i get a
java.sql.generalexception..Probably because by trying to construct the SQL yourself, you are constructing invalid SQL due to the data.
