How to validate incoming messages with mandatory field coming as null/empty

Question

Hi,
I want to validate the incoming messages received by the file adpater.
1. Need to check that all the mandatory fields(minoccurs=1) has values, else it should return fault. But what happening now is even though the mandatory fields are empty/null, file is being read by the file adapter and not getting faulted.
2. I have tried using the Validate Activity/Assign Activity but this is a business fault and not sytem fault, hence no faults are auto generated.
3. We are presently using the if/switch activity and putting the conditions manually in order to validate the mandatory fields and hence it is throwing the business faults explicitly.
4. But if there is 200 fields mandatory out of 500 fields schema, then we need to hardocde manually all 200 fields. Please advise me if this is possible in any dynamic way.
Thanks

Dear vijay,
This is my xsd::
<?xml version="1.0" encoding="UTF-8" ?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns="http://www.example.org"
targetNamespace="http://www.example.org"
elementFormDefault="qualified">
<xsd:element name="exampleElement">
<xsd:annotation>
<xsd:documentation>
A sample element
</xsd:documentation>
</xsd:annotation>
<xsd:complexType>
<xsd:sequence>
*<xsd:element name="element1" type="xsd:string" minOccurs="0"*
nillable="false"/>
*<xsd:element name="element2" type="xsd:int" minOccurs="0"*
nillable="false"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
I tried the above xsd as well as
<?xml version="1.0" encoding="UTF-8" ?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns="http://www.example.org"
targetNamespace="http://www.example.org"
elementFormDefault="qualified">
<xsd:element name="exampleElement">
<xsd:annotation>
<xsd:documentation>
A sample element
</xsd:documentation>
</xsd:annotation>
<xsd:complexType>
<xsd:sequence>
*<xsd:element name="element1" type="xsd:string" minOccurs="1"*
nillable="false"/>
*<xsd:element name="element2" type="xsd:int" minOccurs="1"*
nillable="false"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
But instance is getting completed even though the mandatory string field(element 1) is empty/null like:
<element1></element1>
What I feel is, string will accept all the values whether it is int, date, long and in the same way it is accepting null character.
Please let me know if you have any solutions to overcome this.
Thanks again.
