Cannot find the declaration of element 'emp_comp' - web-services

Question

It seems that I am facing some problem while validating this XML
This is XML ,which I have created.
<?xml version="1.0" encoding="UTF-8"?>
<emp_comp xmlns:xsi="http://www.w3.org/2001/XMLSchema" xsi:noNamespaceSchemaLocation="http://localhost:9080/ermWeb/WebContent/XSD/Compensation.xsd">
<emp>
<row_id>0</row_id>
<emp_code>002</emp_code>
<emp_compdt>01-04-2014</emp_compdt>
<emp_cdata>
<emp_cname>Basic</emp_cname>
<emp_ccurr>INR</emp_ccurr>
<emp_camt>100.00</emp_camt>
</emp_cdata>
</emp>
</emp_comp>
Corresponding schema is
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="emp_comp">
<xs:complexType>
<xs:sequence>

<xs:complexType>
<xs:sequence>
<xs:element name="row_id" type="xs:int" />
<xs:element name="emp_code" type="xs:string"
minOccurs="0" />
<xs:element name="emp_compdt"
minOccurs="0">

<xs:simpleType>

Error which I am getting is Cannot find the declaration of element 'emp_comp'
what could be the reason for this.

Answer 1

Change:
xmlns:xsi="http://www.w3.org/2001/XMLSchema"
To:
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
Then, provided that you do really have your XSD at http://localhost:9080/ermWeb/WebContent/XSD/Compensation.xsd, it will work. Pull it up in a browser to be sure.

Answer 2

Problem
The problem is on first tag, remove this declaration xmlns:xsi="http://www.w3.org/2001/XMLSchema" xsi:noNamespaceSchemaLocation="http://localhost:9080/ermWeb/WebContent/XSD/Compe‌​nsation.xsd" and and fix <emp_compdt>01-APR-2014</emp_compdt>
Possible Solution
Define a namespace on XSD targetNamespace="http://namespace"
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://namespace">
<xs:element name="emp_comp">
<xs:complexType>
<xs:sequence>
<xs:element name="emp" maxOccurs="unbounded">
<xs:complexType>
<xs:sequence>
<xs:element name="row_id" type="xs:int" />
<xs:element name="emp_code" type="xs:string"
minOccurs="0" />
<xs:element name="emp_compdt"
minOccurs="0">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:pattern
value="|([0-3][0-9][\-](Jan|Feb|Mar|Apr|May|Jun|Jul|Aug|Sep|Oct|Nov|Dec|JAN|FEB|MAR|APR|MAY|JUN|JUL|AUG|SEP|OCT|NOV|DEC|jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)[\-][0-9]{4})" />
</xs:restriction>
</xs:simpleType>
</xs:element>
<xs:element name="emp_cdata" minOccurs="0"
maxOccurs="unbounded">
<xs:complexType>
<xs:sequence>
<xs:element name="emp_cname"
type="xs:string" minOccurs="0" />
<xs:element name="emp_ccurr"
type="xs:string" minOccurs="0" />
<xs:element name="emp_camt" minOccurs="0" > <!-- ^\d+\.\d{0,2}$ -->
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:pattern value="[0-9]+(\.[0-9][0-9]?)?" />
</xs:restriction>
</xs:simpleType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
the XML could be
<ns1:emp_comp xmlns:ns1="http://namespace" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://namespace http://localhost:9080/ermWeb/WebContent/XSD/Compensation.xsd">
<emp>
<row_id>0</row_id>
<emp_code>002</emp_code>
<emp_compdt>01-APR-2014</emp_compdt>
<emp_cdata>
<emp_cname>Basic</emp_cname>
<emp_ccurr>INR</emp_ccurr>
<emp_camt>100.00</emp_camt>
</emp_cdata>
</emp>
</ns1:emp_comp>

Answer 3

Ok, this might be first I am answering my own Question
<?xml version="1.0" encoding="UTF-8"?>
<emp_comp xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://localhost:9080/ermWeb/XSD/Compensation.xsd">
<emp>
<row_id>0</row_id>
<emp_code>002</emp_code>
<emp_compdt>01-Jan-2014</emp_compdt>
<emp_cdata>
<emp_cname>Basic</emp_cname>
<emp_ccurr>INR</emp_ccurr>
<emp_camt>100.00</emp_camt>
</emp_cdata>
<emp_cdata>
<emp_cname>VPF</emp_cname>
<emp_ccurr>INR</emp_ccurr>
<emp_camt>120.00</emp_camt>
</emp_cdata>
<emp_cdata>
<emp_cname>Employer NPS</emp_cname>
<emp_ccurr>INR</emp_ccurr>
<emp_camt>130.00</emp_camt>
</emp_cdata>
<emp_cdata>
<emp_cname>Employee NPS</emp_cname>
<emp_ccurr>INR</emp_ccurr>
<emp_camt>140.00</emp_camt>
</emp_cdata>
</emp>
</emp_comp>
there were 3 errors as they are pointed out by other answers.
1)01-04-2014 is incorrect, 04 must be replaced by APR
2)xmlns:xsi="http://www.w3.org/2001/XMLSchema" , must add -instance in the end
and
3) I need to use the XSD resource with the nameSpace ,to do that I have to add noNamespace before SchemaLocation in xsi:
Now XML is getting validated in accordance with XSD.
