Failed to resolve any values for urn:oasis:names:tc:xacml:2.0:subject:role

jorgedso Jul 30, 2012 12:53 PM

Hello everyone,

I tried to basically start using PicketBox XACML using the XACML RBAC Locator examples on this page (employee role): https://community.jboss.org/wiki/XACMLRBACLocator#Permission_Policy_Sets_PPS

And used the following request example: https://community.jboss.org/wiki/XACMLRBACLocator#Employee_Create_Purchase_Order__Permit

When testing using:

org.jboss.security.xacml.sunxacml.PDP

The result of the evaluation was Permit, but it returned also the following warning:

org.jboss.security.xacml.sunxacml.finder.AttributeFinder findAttribute

INFO: Failed to resolve any values for urn:oasis:names:tc:xacml:2.0:subject:role

Is the problem mine? Did I miss some kind of configuration?

I used the following pom dependency:

<groupId>org.jboss.security</groupId>

<artifactId>jboss-xacml</artifactId>

</dependency>

Can you help me please?

Thank you!

Hello again.

I've been mixing sunxacml things. So, I tried to use only jboss xacml objects to simply test the example in https://community.jboss.org/wiki/XACMLRBACLocator

I've created a file called jbossxacml.xml where I put the following content https://community.jboss.org/wiki/XACMLRBACLocator#Variant_2
XACML RBAC Locatorbut commented the manager role lines

In the same place, I created a file called employee-PPS-policyset.xml where I put the following content https://community.jboss.org/wiki/XACMLRBACLocator#Employee_274008
In the same place, I created a file called employee-RPS-policyset.xml where I put the following content https://community.jboss.org/wiki/XACMLRBACLocator#Employee

Then, I created a simple java App with the following code in the class main:
InputStream is = new FileInputStream("/home/jorgedso/Projects/XACML/jbossxacml.xml");
JBossPDP pdp = new JBossPDP(is);

Trying to run the App, there was an exception:
2/Ago/2012 18:30:14 org.jboss.security.xacml.core.JBossPDP addPolicySets
INFO: Reading policysets from location=/home/jorgedso/Projects/XACML/employee-PPS-policyset.xml
Exception in thread "main" java.lang.RuntimeException: java.lang.RuntimeException: Null Inputstream for /home/jorgedso/Projects/XACML/employee-PPS-policyset.xml
at org.jboss.security.xacml.core.JBossPDP.<init>(JBossPDP.java:163)

How can this happen? The content of that file is what I described above. How can it be possible to be Null InputStream? The file exists, obviously.

Can you help?

Thank you!
