Subject Re: Using HTTPS in camel-http when remote side has self-signed cert
Date Thu, 18 Feb 2010 16:26:19 GMT

Hello,
I would like to monitor an HTTPS endpoint and connect to it in two different
ways.  I would like to connect to it in one route using HTTPS w/ client
certificates and in another route using HTTPS using server certificate only. 
The reason for doing this is because all the endpoints I am monitoring
should require client certificates and connecting to the endpoint with HTTPS
with server cert only will produce an alert and I can inform the owner that
their security configuration is wrong.

I tried created two separate beans that implement HttpClientConfigurer.  One
of them will trust all certs:


	     public void configureHttpClient(HttpClient client) {
	         // register the customer SSLFactory
	         ProtocolSocketFactory easy = null;
			try {
				easy = new EasySSLProtocolSocketFactory();
			} catch (GeneralSecurityException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			} catch (IOException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
	         Protocol protocol = new Protocol("https", easy, 17444);
	         Protocol.registerProtocol("https", protocol);

	     }


The other one will have use a keystore/truststore to connect to the
endpoint:


	public void configureHttpClient(HttpClient arg0) {
		Protocol authhttps = null;
		try {
			authhttps = new Protocol("https", new AuthSSLProtocolSocketFactory(
					  new URL("file:" + keystoreLocation), keystorePassword,
					  new URL("file:" + truststoreLocation), truststorePassword), 17444);
		} catch (MalformedURLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (GeneralSecurityException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

		Protocol.registerProtocol("https", authhttps);		
	}

Then in spring, I declare beans for these HTTPS configs:

	<bean id="myHttpClientConfigurerCerts"
		class="gov.wisconsin.wijis.camel.https.WijisHttpClientConfigurerCerts">
			<property name="keystoreLocation" value="${KEYSTORE_LOCATION}"/>
		    <property name="keystorePassword" value="${KEYSTORE_PASSWORD}"/>
			<property name="truststoreLocation" value="${TRUSTSTORE_LOCATION}"/>
			<property name="truststorePassword" value="${TRUSTSTORE_PASSWORD}"/>
	</bean>
	
	<bean id="myHttpClientConfigurerTrustAllCACerts"
class="gov.wisconsin.wijis.camel.https.WijisHttpClientConfigurerTrustAllCACerts"
/>


I refer to these endpoints in a producer template using java code like this
and passing in the http configuration using the registry:

String url =
"http://someURL.com/?httpClientConfigurerRef=myHttpClientConfigurerCerts";
template.sendBodyAndHeader(url, null, Exchange.HTTP_METHOD, "GET");

or

String url =
"http://someURL.com/?httpClientConfigurerRef=myHttpClientConfigurerTrustAllCACerts";
template.sendBodyAndHeader(url, null, Exchange.HTTP_METHOD, "GET");


However the problem I have is that the endpoint which will 'TrustAllCACerts'
is sending using the 'myHttpClientConfigurerCerts' configuration.  This
happens very randomly.  Sometimes it will use the TrustAllCerts
configuration and other times it will use the other one.

I think the answer to my problems might be CompositeHttpConfigurer but I
don't see any examples on how to use that.

Does anyone have any ideas?  

Thanks,
yogesh
