Hi,

I'm a newby with SSO and I'm interested in getting SAML2 in my web app (and possibly others later).

My Web app:

- Client side it's plain js accessing the server only with REST Json requests

- Server side it's a basic Servlet Exposing only some REST APIs (no framework)

Contraint: Server side, I must stick to Java 7 or 8.

Currently the authentication is done using a simple intial POST authhenticate() request and if the authentication is ok, some parameters are maintained in the session to know who is logged and so on...

All this is very basic.

PAC4J seems to be a simple, robust and open solution so I'd like to try it first.

Since I must stick with Java 8 I understood that I must use PAC4J version 4.*

I started to build using maven the following packages:

- j2e-pac4j-4.1.0.jar
- pac4j-core-4.5.7-all.jar.jar
- pac4j-saml-opensamlv3-4.5.7-all.jar
- pac4j-config-4.5.7-all.jar.jar

(even though I had issues with a wrong dependency for xmlsectool, and that I got 1 test failed on pac4j-saml-opensamlv3).

This seems to be correct and sufficient for what I need.

Now, I'm trying to use the souces of the demo in org\pac4j\demo\jee and I'm having some problems.

1) I had to change

final Client client = getSharedConfig().getClients().findClient(request.getParameter(Pac4jConstants.DEFAULT_CLIENT_NAME_PARAMETER)).orElseThrow(() -> new TechnicalException("No client found"));

DemoConfigFactory confFactory = new DemoConfigFactory();
final Client client = confFactory.build().getClients().findClient(request.getParameter(Pac4jConstants.DEFAULT_CLIENT_NAME_PARAMETER)).orElseThrow(() -> new TechnicalException("No client found"));

because I couldn't find any implementation of getSharedConfig()...

Is what I have done correct ?

2) Can't find the CallContext class.

The line:

action = client.getRedirectionAction(new CallContext(context, JEESessionStore.INSTANCE)).get();

popups an error:

CallContext cannot be resolved to a type

I can't find this class anywhhere. I'm sure I'm missing something very basic...

Sorry in advance if these are dumb questions but I can't find any clue on the web.

I'd like to be able to compile this first before I can try to understand the whole thing in details and go with the integration (or ask for an expert to do it)...

Thanks,

Jérôme LELEU

Hi,

Please take a look at: https://github.com/pac4j/jee-pac4j-demo/tree/4.1.x

This demo is dedicated to j2e-pac4j v4.1.

You'll see:

final J2EContext context = new J2EContext(request, response);
	final Client client = ConfigSingleton.getConfig().getClients().findClient(request.getParameter(Pac4jConstants.DEFAULT_CLIENT_NAME_PARAMETER));
	try {
	client.redirect(context);
	} catch (final HttpAction e) {
	}

Thanks.

Best regards,

Jérôme

Hi Jérome,

Thank you a lot for your response!

I actually did try the 4.1 version of the demo going to the specific branch (even though I had a doubt it was necessary since there was no dedicated tag on GitHub) but then I had more problems:

Maybe I need to build another package?

thanks,

Hi,

I just switched to the 4.1.x branch, then set the JDK 8 locally and finally compiled/started the project: mvn clean package jetty:run

And it works.

Thanks.

Best regards,

Jérôme

No luck on my side:

I downloaded the package from GitHub using the URL you provided, then Code > Download Zip and copied it in C:\Users\Eric\Desktop\PAC4J\ then ran the command as you did:

C:\Users\Eric\Desktop\PAC4J\jee-pac4j-demo-4.1.x>mvn clean package jetty:run

Any idea ?

Ok.

I decided to give it a last chance and to restart from scratch.

Step#1: building "pac4j-4.1.x" (java 8)

i) I downloaded the zip file from https://github.com/pac4j/pac4j/tree/4.1.x

ii) unzip it

iii) mvn clean package

Result:

What's wrong with me guys? this seems a very simple procedure and I don't see what I could do wrong...

Does someone has some experience with pac4j with Java 8 ? maybe it is just not maintained anymore and deprecated ?

Thanks,

Hi,

I just removed the xmlsectool dependency from my Maven repo and called again: maven clean package jetty:run
