During XACML Policy published issue in WSO2 API

Question

After creating the XACML Policy trying to publish it to PDP, but getting error

Could you please suggest to resolve the above error.

Answer 1

I too encountered this issue and the reason was due to some conflicts of copying org.wso2.carbon.identity.entitlement.stub jars in different versions when installing XACML via feature manager. If you are installing XACML 2.2 and XACML mediator 2.2 it should copy org.wso2.carbon.identity.entitlement.stub 4.2.1. I could resolve it as follows,

1. Go to /repository/components and open artifacts.xml. Find the artifact id 'org.wso2.carbon.identity.entitlement.stub and change the version to 4.2.1 (there may have two artifacts with different versions 4.2.0 and 4.2.1)
2. Go to /repository/components/default/configuration/org.eclipse.equinox.simpleconfigurator and open bundles.info file. Find the line org.wso2.carbon.identity.entitlement.stub,4.2.0 and remove it. (there should be a same entry with version 4.2.1)

Then try to publish to PDP

This has been already answered by an another SO answer, You also can check it for more details. Please find from here. If you are using APIM 1.7.0 and If you install XACML feature 4.2.2, you would not see such error.
