jsf: transfer data from one listbox to another

Easiesy way should be using the binding attribute.

JSF<h:selectOneListbox binding="#{myBean.listbox1}" />

<h:selectOneListbox binding="#{myBean.listbox2}" />

<h:commandButton action="#{myBean.moveData}" />

Beanprivate HtmlSelectOneListbox listbox1;

private HtmlSelectOneListbox listbox2;

// plus getters and setters

public void moveData() {

listbox2.setValue(listbox1.getValue());

}

Untested, but this might give you an idea anyway.

[code]Hi,

this is one way it is right or wrong i dont know but it is working for me

jsp page

<h:panelGroup>

<h:selectOneMenu id="host" binding="#{HRselforeachappvm.selectonelist}" value="#{HRselforeachappvm.host}"

valueChangeListener="#{HRselforeachappvm.hostSelection}" onchange="submit();"immediate="true" required="true">

<f:selectItem itemValue="" itemLabel=""/>

<f:selectItems value="#{HRselforeachappvm.hosts}"/>

</h:selectOneMenu>

<h:message for="host" style="color:red"/>

</h:panelGroup>

<h:outputText value="SelectAPPlication" />

<h:panelGroup>

<h:selectOneMenu id="appcpu" value="#{HRselforeachappvm.user}" required="true">

<f:selectItem itemValue="" itemLabel=" "/>

<f:selectItems value="#{HRselforeachappvm.users}"/>

</h:selectOneMenu>

backing bean

public void setSelectonelist(UISelectOne selectone){

this.selectone=selectone;

}

public UISelectOne getSelectonelist(){

return selectone;

}

public void hostSelection(ValueChangeEvent ee)

throws AbortProcessingException

{

System.out.println("valuechangeevent");

FacesContext context = FacesContext.getCurrentInstance();

getUsers();

context.renderResponse();

}

public Map getUsers(){

try{

if(selectone!=null)

hostselected= (String)selectone.getLocalValue();// v .v imp note

else

hostselected=" ";

System.out.println("getting the selectedhost"+hostselected);

openConnection();

String str="select distinct pd_user from sp_process_detail_current where host_id=?";

System.out.println("setting users from host");

ps=con.prepareStatement(str);

ps.setString(1,hostselected);

ps.execute();

rs=ps.getResultSet();

while(rs.next()){

pd_user=rs.getString("pd_user");

System.out.println(pd_user);

selusernames.put(pd_user,pd_user);

}

return selusernames;

}

catch(SQLException e){

e.printStackTrace();

}

catch(Exception e){

e.printStackTrace();

}

finally{

try{

if(rs!=null)

rs.close();

rs=null;

}

catch(SQLException e){

e.printStackTrace();

}

try{

if(ps!=null)

ps.close();

ps=null;

}

catch(SQLException e){

e.printStackTrace();

}

try{

close();

}

catch(SQLException e){

e.printStackTrace();

}

}

return selusernames;

}

[b]HI BalusC ,

ya but without local submitting onchange="submit();"

value change listener does not work.

actually the value change listener example

is like that in core java server faces.

but i tried with out using local submitting

onchange=submi();"

but it is not working

you also try that

with regards
