Warn in log when loading ContextAndPolicyConfiguration.xml

[Sylvain LF]

Hello,

I'm starting with your pdp implementation. With your example, everything works well (policy and context load).

However when i try to load "ContextAndPolicyConfiguration.xml" (http://svn.herasaf.org/herasaf-xacml/tags/0.12.0/herasaf-xacml-integrationtests/src/test/resources/config/),i get 2 warns :

Code:

09:51:59.588 [main] WARN  o.h.x.c.u.ContextAndPolicyConfiguration - Validating turned off because schema could not be initialized.

I changed this :

Code:

<schemaByPath>
   file:src/test/resources/xacmlSchema/access_control-xacml-2.0-policy-schema-os.xml
</schemaByPath>

by my own pathfile, but i always 2 warns.

Is this normal ?

Hi Sylvain,
That should not be.

May I ask you how you use our library?
Did you download the sourcecode via SVN and let it run, or did you download one of these JARs from here http://maven.herasaf.org/artifactory/repo/org/herasaf/xacml/herasaf-xacml-assembly/0.12.0/ ?
I am asking that because the path points to the src/test/resources....
Please ensure that the src/test/resources/xacmlSchema/access_control-xacml-2.0-policy-schema-os.xml file is available in your classpath at this location.

Let me know if I could help you.

Regards,
Florian

Hi Florian,

Thanks for you quick answer.

I've downloaded your pdp implementation via SVN as Maven Project, then i've installed in my Maven Repository.

So my project is new Maven Project, and i write all dependencies in my "pom.xml" like that :

Code:

  <dependency>
<groupId>org.herasaf.xacml</groupId>
<artifactId>herasaf-xacml-referenceloader</artifactId>
<version>0.12.0</version>
</dependency>
<dependency>
<groupId>org.herasaf.xacml</groupId>
<artifactId>herasaf-xacml-locator</artifactId>
<version>0.12.0</version>
</dependency>
<dependency>
<groupId>org.herasaf.xacml</groupId>
<artifactId>herasaf-xacml-persistence</artifactId>
<version>0.12.0</version>
</dependency>
<dependency>
<groupId>org.herasaf.xacml</groupId>
<artifactId>herasaf-xacml-evaluatablepreprocess</artifactId>
<version>0.12.0</version>
</dependency>
 
  <dependency>
<groupId>org.herasaf.xacml</groupId>
<artifactId>herasaf-xacml-core</artifactId>
<version>0.12.0</version>
</dependency>
  <dependency>
<groupId>org.herasaf.xacml</groupId>
<artifactId>herasaf-xacml-pdp</artifactId>
<version>0.12.0</version>
</dependency>

I changed the path src/test/resources/xacmlSchema/access_control-xacml-2.0-policy-schema-os.xml by this C:/Dvp/Projects/SANDBOX/Core/src/main/java/xacmlSchema/access_control-xacml-2.0-policy-schema-os.xsd and the file exists.

These are the only changes I have done.

Regards,

SLF

Hi Sylvain,

I just tested it and here it works.
I tried with the following path:
file:D:/Documents/Projects/HERASAF/workspace_xacml/herasaf-xacml-integrationtests/src/test/resources/XacmlSchema/access_control-xacml-2.0-policy-schema-os.xml
and I have no warning.

What I saw in you post is that your path points to:
C:/Dvp/Projects/SANDBOX/Core/src/main/java/xacmlSchema/access_control-xacml-2.0-policy-schema-os.xsd, that shouldn't be an XSD.
Maybe that's the reason for the warning?

By the way: The warning means that the file was not found.

Florian

Hi Florian,

This is my "ContextAndPolicyConfiguration.xml" :

Code:

So i moved my config files from "src/main/java" to "src/main/ressources".

Now i get 3 warns, and when the line : "[main] DEBUG o.s.b.f.x.DefaultBeanDefinitionDocumentReader - Loading bean definitions" show in console, application wait during about 20 secondes.

This is my whole log with your PolicyStressTest001.xml :

Hi Sylvain,

It's a little bit strange because I cannot reproduce the error.

Could you please try to change all 3 schemaByPath elements (request, response and policy) to classpath (like request), would that be possible?
Classpath is probably the easiest way.

If it is not possible, or does not work, would it be possible to provide me with your test-class where the error occurs?

Regards,
Florian

Hi Sylvain

You probably already know what I'm going to explain, but maybe I can give a little bit more transparancy to the resource handling.

It was correct from you to move your config files to src/main/resources.
Maven processes only *.java files in src/main/java. All other files type will not be processed/exported when they are in src/main/java.
So, config and other resources must be placed in src/main/resources. They will then also be exported to the classpath.
That means that content from src/main/java and src/main/resources will be exported to the root of the runtime classpath.

In addition do the classloaders and classloader hirarchies influence the resource loading. That's because getResourceAsStream is depending on the classloader.
So it can be that you expirience differences depending on the way you start your application. E.g. launching by a simple java main or by a JUnit test or by a maven build can resolve relative paths differently.
To get around those differences it is the best method to use the resource abstraction by spring. You can do that with the classpath keyword in resource addressing like:
classpath:/config/filename.xml.
Spring will (in the example above) look for a file in a config folder inside the root of the classpath. In your project structure that could be src/main/resources/config/filename.xml

I hope that helps a little bit.

René

Hi René,

Thank you for your clarification.

I've changed 3 "schemaByPath" elements to "classpath" elements, despite this, i've again 2 warns.

If the pathfile of "classpath" elements doesn't exists, an error occurs :

I've post my project with this post.

Thank you for your help and your patience.

Hi,

It's a little bit strange. I'll try to have a look at your project tomorrow.

Regards,
Florian

[Florian Huonder]

Good morning,

I got your code running.
There were two minor errors.

• The Maven folder for the resources is called src/main/resources, you named it src/main/ressources by mistake. Don't forget to also adapt the path in the Core-Class where you load the policy from.
• In the ContextAndPolicyConfiguration.xml in the response part you wrote xacmlSchemae instead of xacmlSchema in the path.

I hope I could help you.

Regards,
Florian

PS. You should run HERAS^AF with Java 1.5.

[Sylvain LF]

Good morning,

Thank you for yours corrections.

We finally found the source of warnings.

We have 2 <schemaByPath> like this in the ContextAndPolicyConfiguration.xml :

Code:

<schemaByPath>
    classpath:/xacmlSchema/access_control-xacml-2.0-context-schema-os.xml
</schemaByPath>

However, in the header of the file access_control-xacml-2.0-context-schema-os.xml, there are :

Code:

<xs:import namespace="urn:oasis:names:tc:xacml:2.0:policy:schema:os" schemaLocation="http://docs.oasis-open.org/xacml/access_control-xacml-2.0-policy-schema-os.xsd"/>

If we changed schemaLocation by a local file (E.G. schemaLocation="C:/access_control-xacml-2.0-policy-schema-os.xsd"), warns disappear.

We believe that the problem comes from our proxy.

Thank you for your help and especially your patience.

Best regards,

SLF
