Hi,
I’m trying to use dhtmlxConnector with dhtmlxCombo. To implement it, i’m using the java version of dhtmlxConnector, and i make a servlet(Proj_List.java) with this information:
ComboConnector c = new ComboConnector(conn,DBType.Oracle);
c.render_sql(“SELECT proj_short_name ID FROM project”,“proj_short_name(ID)”,“ID”);
And then, in the HTML, i created the control:
Finally, in the web.xml i wrote the next servlet mapping:
ProjList
Proj_List
ProjList
/ProjList.do
The problem is that when launch the web, it throws the following error:
GRAVE: Servlet.service() para servlet Generation lanzó excepción
