jsp - get the value selected in dropdownlist in spring mvc hibernate mysql -


Hi, I am writing an application in Spring MVC Hibernate Annotation. Here two tables are used to keep employee details. And the other to keep the team's expanses (team tables) Here I am using the drop down box in my JSP to select the team name so that all the staff can be related to that team. But I'm stuck here, I can not get the selected team.What do I want to do when I select a team, like Team 1, I want to show all the employees come under Team 1.

To select the name of the team from my SSP database, my Jasps sprite and dropdown list here show all the names from the team table

 < Code> & lt; Tr & gt; & Lt; TD & gt; & Lt; Form: label path = "teams.teamId" & gt; Team name & lt; / Form: label & gt; & Lt; / TD & gt; & Lt; TD & gt; & Lt; Form: Select Path = "teams.teamId" cssStyle = "width: 150px;" & Gt; & Lt; Option value = "- 1" & gt; Choose a type & lt; / Options & gt; & Lt; Almost every item for c: "$ {teamKey}" var = "teams" & gt; & Lt; Option value = "$ {teams.teamId}" & gt; $ {Teams.teamName} & lt; / Options & gt; & Lt; / C: foreach & gt; & Lt; / Form: Selection & gt; & Lt; / TR & gt;

GetTeamId ()); Map & lt; string, object & gt; model = new hashmop & lt; string; object & gt; (); Model.put ("resourcekey", resourceServices.listResources ()); Model.put ("teamKey", addteamServices.listTeams ()); New model and visual flame ("Search", model);}
