MDS-01333: missing element "mds-config"

While compiling a SOA Suite 11g composite you might get an issue like this

Error(12,61): Parse of component type files failed, check the adf-config.xml file : "oracle.fabric.common.FabricException: oracle.mds.config.MDSConfigurationException: MDS-01333: missing element "mds-config": MDS-01333: missing element "mds-config": oracle.mds.config.MDSConfigurationException: MDS-01333: missing element "mds-config": MDS-01333: missing element "mds-config""

don't know the exact reason how to reproduce this issue.

I just got one project from one of my colleague and while i was trying to compile this i got the above error.

This error is because of some misconfiguration or error in ADF-config.xml

I just checked the file and i found following entry

<?xml version="1.0" encoding="windows-1252" ?>
<adf-config xmlns="http://xmlns.oracle.com/adf/config"
xmlns:adf="http://xmlns.oracle.com/adf/config/properties">
<adf:adf-properties-child xmlns="http://xmlns.oracle.com/adf/config/properties">
<adf-property name="adfAppUID" value="Frustu-4655"/>
</adf:adf-properties-child>
</adf-config>

I compared it with the other adf-config.xml file that i have in my environment and find it was quite different.

Just did some research in net and got this forum link

Just copied the adf-config.xml file from there which is

<?xml version="1.0" encoding="windows-1252" ?>
<adf-config xmlns="http://xmlns.oracle.com/adf/config"
xmlns:adf="http://xmlns.oracle.com/adf/config/properties">
<adf:adf-properties-child xmlns="http://xmlns.oracle.com/adf/config/properties">
<adf-property name="adfAppUID" value="Tryout-4147"/>
</adf:adf-properties-child>
<adf-mds-config xmlns="http://xmlns.oracle.com/adf/mds/config">
<mds-config xmlns="http://xmlns.oracle.com/mds/config">
<persistence-config>
<metadata-namespaces>
<namespace metadata-store-usage="mstore-usage_1" path="/soa/shared"/>
</metadata-namespaces>
<metadata-store-usages>
<metadata-store-usage id="mstore-usage_1">
<metadata-store class-name="oracle.mds.persistence.stores.file.FileMetadataStore">
<property value="${oracle.home}/integration" name="metadata-path"/>
<property value="seed" name="partition-name"/>
</metadata-store>
</metadata-store-usage>
</metadata-store-usages>
</persistence-config>
</mds-config>
</adf-mds-config>
</adf-config>

and in stead of value Tryout-4147 i replaced it with my project name Frustu-4655 and to my surprise i was able to compile it successfully.
