> +Question:+
> RuntimeException after adding MongoDB policy provider extension
> +Description:+
> I have made my own MongoDBPolicyProvider and I have integrated it into Authzforce server, but I'm unable to start the webapp (docker image fiware/authzforce-ce-server, release-8.1.0) because of this exception:
> java.lang.RuntimeException: Invalid PDP configuration of domain 'YAT-5z9ZEemGyAJCrBEAAg' in file '/opt/authzforce-ce-server/data/domains/YAT-5z9ZEemGyAJCrBEAAg/pdp.xml': refPolicyProvider is not an instance of class org.ow2.authzforce.pap.dao.flatfile.xmlns.StaticFlatFileDAORefPolicyProvider as expected.
> I think that somehow it is still trying to retrieve policies from a StaticFlatFileDAORefPolicyProvider policy provider.
> The extension's .jar is visible in server's classpath.
> Here is my pdp configuration file:
> <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
> <pdp
>     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
>     xmlns="http://authzforce.github.io/core/xmlns/pdp/6.0"
>     xmlns:oa="urn:oasis:names:tc:xacml:3.0:core:schema:wd-17"
>     version="6.0.0" enableXPath="false" strictAttributeIssuerMatch="false" maxVariableRefDepth="10" maxPolicyRefDepth="10">
>     <refPolicyProvider
>         id="refPolicyProvider"
>         xmlns:ext="PRP/mongoDB"
>         xsi:type="ext:MongoDBBasedPolicyProviderDescriptor"
>         serverHost="localhost" serverPort="27017" dbName="PRP" collectionName="policies" />
>     <rootPolicyProvider id="rootPolicyProvider" xsi:type="StaticRefBasedRootPolicyProvider">
>        <policyRef>root-rbac-policyset</policyRef>
>     </rootPolicyProvider>
> </pdp>
> This is the MongoDBBasedPolicyProviderDescriptor:
> @XmlAccessorType(XmlAccessType.FIELD)
> @XmlType(name = "MongoDBBasedPolicyProviderDescriptor")
> @Getter
> @Setter
> @NoArgsConstructor
> @AllArgsConstructor
> public class MongoDBBasedPolicyProviderDescriptor extends AbstractPolicyProvider
> {
>     @XmlAttribute(name = "serverHost", required = true)
>     protected String serverHost;
>     @XmlAttribute(name = "serverPort", required = true)
>     protected int serverPort;
>     @XmlAttribute(name = "dbName", required = true)
>     protected String dbName;
>     @XmlAttribute(name = "collectionName", required = true)
>     protected String collectionName;
> }
> I have done the process of integrating the PRP twice now, but I haven't been successful yet. I would appreciate any help in this direction.
