Re: html:optionsCollection problem

I´ve added it into a <html:form action="nameaction.do"> but I obtain the error 

Cannot create iterator for [EMAIL PROTECTED]
I´ve modified some code because I want to obtain a select with all info of a table which is placed in a database when the page is loaded; and this page only comes from a link, not from another page with an associated action (therefore, nothing has been saved in session). 

public class Prueba implements Serializable
{
        private Collection empresas=new ArrayList();
        DTOEmpresa empresa = new DTOEmpresa();

        public Collection getEmpresas()
        {
                empresa.setNifEmpresa("A11111111");
                empresas.add(empresa);
                return(empresas);
        }
        public void setEmpresas(String empresa)
        {
                empresas.add(empresa);
        }
}

<jsp:useBean id="test" class="project.struts.General.Prueba"/>
   <html:select property="rempresa">
   <html:options collection="test" property="nifempresa"/>
</html:select>


I don´t know if I have explained my issue as I should.

Thanks a lot.

Looks like it may not be wrapped in a <html:form> tag in your JSP.  You
probably also want a field named "toSelect", with accessor and mutators in
your form bean, to hold the selected value.

Hi,

I have a Bean:

package project.struts.General;
import java.util.ArrayList;
import java.util.Collection;
import java.io.*;

public class Prueba implements Serializable
{
   private Collection empresas=new ArrayList();

   public Collection getEmpresas()
   {
       empresas.add("string1");
       empresas.add("string2");
       return(empresas);
   }
}

and a jsp where I write:

<jsp:useBean id="test" class="project.struts.General.Prueba" />
<html:select property="toSelect">
   <html:optionsCollection property="empresas" name="test"/>
</html:select>

But it doesn't work. I receive the error
javax.servlet.ServletException: Cannot find bean under name
org.apache.struts.taglib.html.BEAN

How can I solve this issue? Or what is the correct way to generate this?

Thanks in advance
