Get sequence value

Question

Hi,
Im trying to get a sequence value in my jsf application.
I thought doing it like this:
    public int getRunNumber(){
        int runNumber=0;
        CallableStatement plsqlBlock = null;
        DBTransaction trans = getDBTransaction();
        String statement = "BEGIN SELECT XXA_RUN_NUMBER_S.nextval :1 FROM dual; END;";
        plsqlBlock = trans.createCallableStatement(statement,0);
        try{
            plsqlBlock.registerOutParameter(1,OracleTypes.NUMBER);
            plsqlBlock.execute();
            System.out.println(runNumber);
            trans.commit();
        catch (SQLException e){
            e.printStackTrace();
        finally {
            try{
                plsqlBlock.close();
            catch (SQLException e){
                e.printStackTrace();
        return runNumber;
    }But that doesn't work it gives: JBO-27121: SQL error during statement execution.
Any suggestions?

Klaas,
You said:
But that .. gives: JBO-27121: SQL error during statement execution.Of-course, because you forgot the INTO keyword in your anonymous PL/SQL block.
This thread may help:
Re: returning value from a PL/SQL block.
Or maybe this...
[NOTE: Uncompiled and untested.]
String sql = "begin select XXA_RUN_NUMBER_S.nextval into ? from DUAL; end;"
Connection c = // However you get it.
CallableStatement cs = c.prepareCall(sql);
cs.registerOutParameter(1, Types.NUMERIC);
cs.execute();
BigDecimal nextVal = cs.getBigDecimal(1);Good Luck,
Avi.
