AS2 Client - https

[cairnechan]

I see as2 client support https but cannot find any api, please advise any example thanks

v2.2.8 - 2016-05-09
Improved AS2 client https customization and API

[phax]

Version 2.2.8 was a long time ago :)
You are right, there are no explicit APIs for this.
This was a fix #20 where you are allowed to overload some stuff in the AbstractHttpSenderModule (namely createSSLContext () and createHostnameVerifier ()). That ,means you can create a sublcass of AS2SenderModule where you overload these methods, and than invoke as2Client.setAS2SenderModuleFactory (MyAS2SenderModule::new); to set the new factory.

@phax thanks, what's more, may I ask how to add https(ssl_protocol, ssl_keystore, ssl_keystore_password) on AS2ReceiverModule

[phax]

I don't fully understand your request.
You need a server-like component to request something - e.g. the standalone as2-server or an application server based solution using e.g. as2-servlet. The configuration on how to receive something via https depends on what you are using to receive something.
With the AS2Client directly, you can only get synchronous MDNs back. Asnychronous MDNs must be handled externally and cannot be dealt with by AS2Client.

@phax yes, I configure AS2ReceiverModule in standalone as2-server which can successfully handle as2(http) request. For https, I add these attributes(ssl_protocol, ssl_keystore, ssl_keystore_password) on AS2ReceiverModule but it does not works with as2(https)

[phax]

I must admit I have no idea.
I'm using https only on Tomcat, by adding an httpd in front, to perform the SSL handshake. I have no experience on how to perform this "standalone" :(

Closed by accident

@phax I enable https service by using tomcat embed in spring-boot. But now I have trouble reusing AS2ReceiverHandler since it use socket io(I can retrieve ServletRequest and ServletResponse from sprint-boot controller). Could you please adivse, thanks

[phax]

Well okay, here are some questions:
a) are you using as2-servlet or are you using the as2-server?
b) Did you have a look at how this can be configured in Tomcat: (e.g. https://tomcat.apache.org/tomcat-7.0-doc/ssl-howto.html for Tomcat 7)?

[cairnechan]

I use as2-server at the beginning, find it was using socket io. Shall I turn to as2-servlet?
Because I am using spring-boot, which contain a tomcat server inside and simplify the configuration, I follow this configuration to enable https (step2 https://drissamri.be/blog/java/enable-https-in-spring-boot ), it looks like

server.port=8443
server.ssl.key-store=keystore/client-certs.p12
server.ssl.key-store-password=mypassword
server.ssl.keyStoreType=PKCS12
server.ssl.keyAlias=fwks

[phax]

Yes, please switch to the as2-servlet. Spring boot obviously embedds Tomcat, and Tomcat can (to my knowledge) only handle Servlets.
If you can provide a wrapper around the as2-demo-webapp I'm also happy to publish it here....

[cairnechan]

I turn to as2-servlet now, and regist AS2ReceiveServlet into spring-boot in this way

@Configuration
public class ServletConfiguration {

	@Bean
	public ServletRegistrationBean AS2ReceiveServlet() {
		ServletRegistrationBean register = new ServletRegistrationBean(new AS2ReceiveServlet(), "/as2");
		register.addInitParameter("as2-servlet-config-filename", "config/config.xml");
		return register;
	}
	
}

However it fail to initialze this servlet, and throw the following exception

......
Caused by: java.lang.IllegalStateException: No global scope object has been set!
	at com.helger.scope.mgr.ScopeManager.getGlobalScope(ScopeManager.java:158)
	at com.helger.scope.singleton.AbstractGlobalSingleton._getStaticScope(AbstractGlobalSingleton.java:48)
	at com.helger.scope.singleton.AbstractGlobalSingleton.getGlobalSingleton(AbstractGlobalSingleton.java:65)
	at com.helger.xservlet.servletstatus.ServletStatusManager.getInstance(ServletStatusManager.java:67)
	at com.helger.xservlet.AbstractXServlet.<init>(AbstractXServlet.java:182)
	at com.helger.as2servlet.AS2ReceiveServlet.<init>(AS2ReceiveServlet.java:32)

Could you please advise

[phax]

You need an additional bean that requires the ServletContext.
Upon creation, you need to call:

WebScopeManager.onGlobalBegin (ServletContext);

and for shutdown you need to invoke:

WebScopeManager.onGlobalEnd ();

[cairnechan]

it works now, many thanks

	@Bean
	public ServletRegistrationBean AS2ReceiveServlet(ServletContext servletContext) {
		WebScopeManager.onGlobalBegin(servletContext);
		ServletRegistrationBean register = new ServletRegistrationBean(new AS2ReceiveServlet(), "/as2");
		register.addInitParameter("as2-servlet-config-filename", "config/config.xml");
		return register;
	}

I did this but when I register the AS2WebAppListener, it also tries to set the global scope and throws an exception that global scope has already been set

[phax]

@kalkrishnan This is preferrably used in the WebAppListener - remove it from the servlet than

[kalkrishnan]

WHen I removed it from the servlet, it again gave me an error of no global scope. I ended up keeping it in my servlet and defining my own listener which doesnt define a global scope and that worked.
