I have a doubt in pre-populating a dropdown listbox in Struts ..while loading the JSP itslef the listbox has to be populated. I have a JavaBean wich has a method called getDetailsinHt() which is returning hashtable its something like this- ht.put((new Long(LoginId )),sDetails); sDetails is a String array - String[] sDetails = new String[4]; this string array contains first,middle and last names How canI do this.I havebeen doing this since hours but in vain..:( someody plez help me. The code is like this: Test { public Test{} public long id; public String name[]; public long getId() { return (id); } public void setId(long id) { this.id = id; } public String[] getNames() { return this.name; } public void setName(String[] name) { this.name = name; } public Hashtable getDetailsinHt() { Hashtable ht=new Hashtable(); String[] sDetails = new String[4]; sDetails[0] = "Name"; sDetails[1] = "Name"; sDetails[2] = "Name"; ht.put((new Long(LoginId )),sDetails); return ht; } } in my ActionForm I'm writing theget andset methods like public Hashtable getUserId() { return userId; public void setUserId(Hashtable userId) { this.userId= userId; } public Hashtable getList() { UserList iab=new UserList(); try { Hashtable users=iab.getUserList(0); }catch(Exception e){} return users; } and in my JSP I'm giving as <bean:define id="list" name="createIssueForm" property="userId" type="java.util.Hashtable"/> <html:select property="users" size="1"> <html:options collection="list" property="id" labelProperty="name"/> </html:select> but I'm not able to populate the list box.....here I guess I'm doing something wrong with the ------ property="id" labelProperty="name"/> Can somebodt plez tellme where I'm wrong??
