Using DB Sequence

By Overriding Create in VOImpl

    protected void create(AttributeList attributeList) {
        super.create(attributeList);
        SequenceImpl seq = new SequenceImpl("<DB_seq_name>", getDBTransaction());
        Number seqNextval = seq.getSequenceNumber();
        setLpLocationId(seqNextval);
    }

 

 

By EL exp:

Go to Entity Attribute. Click on Expression. then provide the following line in the 'value' field

(new oracle.jbo.server.SequenceImpl("<DB_seq_name>",adf.object.getDBTransaction())).getSequenceNumber()
