html:optionsCollection problem
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

Thanks a lot for you help!!!!! I've got it!!! At the end my problem was that
the info didn't arrive to the session.
First I've checked if info came to the jsp with c:out and then I've use the
html:select...

Re: html:optionsCollection problem
Posted by Francisco Exposito Aguilera <fc...@hotmail.com>.
I´ve added it into a <html:form action="nameaction.do"> but I obtain the
error
Cannot create iterator for project.struts.General.Prueba@3fc47c
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.
