Hi,

I want to customize a widget in web forms.
I have the following reuirements:
1). fetching data from database and displaying in the combo box widget.
2) validating the date (calender widget)

Hi,

For your second point, doesn't the following work for you? It should display a calendar.

<xs:element name="date" type="xs:date"/>‍

For your first point, you can use the XSD import (or include) element, something like this:

<xs:include schemaLocation="/list-lookup-pages/products.xsd"/>‍

The URL references a resource that can be found on the AVM staging sandbox. It will use the preview tomcat server to evaluate and return the results of this resource for you. This means that you can actually refer to a JSP instead of a static XSD fragment. Like so:

<xs:include schemaLocation="/list-lookup-pages/products.xsd.jsp"/>‍

As long as the results from the JSP page is a valid XSD inclusion, then that's fine. So, you can write code within the JSP that makes the appropriate calls to your database and constructs well-formed XSD output.

Here's a complete example:
(I switch to using the 'import' element instead of the 'include', to show a cleaner namespaced approach)

The main web-form:

<?xml version="1.0"?>
<xs:schema
   xmlns:xs="http://www.w3.org/2001/XMLSchema"
   xmlns:alf="http://www.alfresco.com/"
   xmlns:prodlist="http://www.ixxus.co.uk/myproject/prodlist"
   xmlns:product="http://www.ixxus.co.uk/myproject/product"
   targetNamespace="http://www.ixxus.co.uk/myproject/product"
   elementFormDefault="qualified">

   <xs:import schemaLocation="/list-lookup-pages/products.xsd.jsp" namespace="http://www.ixxus.co.uk/myproject/prodlist'/>

   <xs:element name="product">
      <xs:complexType>
         <xs:sequence>
            <xs:element name="quantity" type="xs:integer"/>
            <xs:element name="product" type="prodlist:prodlookup" minOccurs="1" maxOccurs="unbounded"/>
         </xs:sequence>
      </xs:complexType>
   </xs:element>
</xs:schema>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

The /list-lookup-pages/product.xsd.jsp page should generate output that looks like the following:

<xs:schema
   xmlns:xs="http://www.w3.org/2001/XMLSchema"
   xmlns:alf="http://www.alfresco.com/"
   xmlns:prodlist="http://www.ixxus.co.uk/myproject/prodlist"
   targetNamespace="http://www.ixxus.co.uk/myproject/prodlist"
   elementFormDefault="qualified">

   <xs:simpleType name="prodlookup">
      <xs:restriction base="xs:normalizedString">
         <xs:enumeration value="Product 1"/>
         <xs:enumeration value="Product 2"/>
         <xs:enumeration value="Product 3"/>
         <xs:enumeration value="Product 4"/>
         <xs:enumeration value="Product 5"/>
      </xs:restriction>
   </xs:simpleType>
</xs:schema>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Don't forget to set the encoding correctly from the JSP response.

Is that helpful?

Tom.
