References not ordered

Question

[2] is my third citation, and others looks like this.

I expect something like [3][4][5][6][7][8]

I use jabref. How could I resolve this?

I am aware of this How to get sequential references in my paper? however I haven't gotten it. Someone could give more details to fix this. [svjour] is a springer class

For example, this is the first three of the citations above in the ref.bib file (ref.bib is in the same folder with the .tex file) Please note: I observed the citations are ordered in the output the same way they are ordered in the .bib file. Also, entries in ref.bib is ordered alphabetically. I would like to order them in "chronologically" in terms of its position of citation. A sample content of the .bib file is shown below. There are a few references (not from the ones cited) in between (but I have tried to conserve space)

@InProceedings{ade...,

Pages                    = {1--3}
}
