Display coordinates on the map with gmap

Display coordinates on the map with gmap

I want to get coordinates of the database and show them on the map along with the marker, but I can not. I think there is something missing in the view . It should show only the last location data stored in the DB.

Can anyone help me? The problem is that it fetches the data in the database, and if I manually enter the coordinates the map displays. So I do not think it's an error with the API key, but if I try to fetch from class gadoBean it does not search.

Follow the code below:

Vector ordering XtraGridView - Where with variable

score 0 · Answer 1

Can you tell if the coordinate is correct?

What I noticed is that the center="# {gadoBean.center}" should contain Latitude and Longitude.

Example:

center="#{meuBean.latitude}, #{meuBean.longitude}"

Where:

private BigDecimal latitude;  
private BigDecimal longitude;

Treco on PrimeFaces

<p:gmap center="#{meuBean.latitude}, #{meuBean.longitude}" zoom="13" type="HYBRID" styleClass="ms-mapas" model="#{meuBean.mapa}" />
