Opening an https connection from within a Servlet.

I am having problems trying to establish an HTTPS connection to a servlet from within a different servlet.
I get the java.net.MalformedURLException: unknown protocol: https. SSL is setup for the web server. Direct connections from the browser to a servlet work fine with SSL, but a connection from one servlet to another servlet fails. I'm stumped. Is there a separate SSL install/configuration required for the servlet engine? Could anyone explain?

When you set up SSL enabled web server, you should be getting a trust cert file that knows the hand shake protocol to talk to that server. Once you have that file, you can load that file from that servlet using System.load and then you would be able to talk to anything that runs on that SSL enabled Web server.
Also you must have JSSE jar files installed in your system .

Let me know if you still have problems

HTTPS connection from portal to external webserver

Hi,
I am looking for a way to open a HTTPS connection from portal server to an external webserver. According to <a href="http://help.sap.com/saphelp_nw04/helpdata/en/e2/71c83edf72e16be10000000a114084/content.htm">SAP</a> the code should look like
KeyStore keystoreCAs = ...
SecureConnectionFactory factory = new SecureConnectionFactory(keystoreCAs, null);
HttpURLConnection con = factory.createURLConnection("https://www.mycompany.com");
Does not look difficult, but how do I create the keystore object? The keystore object should somehow be connected to the portal server's keystore which manages the certificates of trusted Certificate Authorities.
Any ideas?
Regards,
Martin

Hi,
meanwhile I solved the problem by my own. The solution slightly simplified is given below.
javax.naming.InitialContext ctx = new javax.naming.InitialContext();
java.lang.Object o = ctx.lookup("keystore");
com.sap.engine.services.keystore.interfaces.KeystoreManagerWrapper_Stub manager = (com.sap.engine.services.keystore.interfaces.KeystoreManagerWrapper_Stub) o;
java.security.KeyStore keystoreCAs = manager.getKeystore("TrustedCAs");
com.sap.security.core.server.https.SecureConnectionFactory factory = new SecureConnectionFactory(keystoreCAs, null);
java.net.HttpURLConnection con = factory.createURLConnection("https://www.mycompany.com");
For connecting via a proxy the host name and port number of the proxy have to be set as System properties using "https.proxyHost" and "https.proxyPort".
java.util.Properties systemSettings = System.getProperties();
 systemSettings.put("proxySet", "true");
 systemSettings.put("https.proxyHost","192.168.0.1") ;
 systemSettings.put("https.proxyPort", "80") ;
Additionally you have to make sure that the server's certificate is issued by a trusted Certification Authority (Must have an entry in your Keystore "TrustedCAs"). To verify this use the Visual Administrator and view service "Key Storage".

HTTPS connection from servlet to another webserver

Hi,
We want to make a https connection from a servlet in weblogic server to another
web server (not necessarily weblogic). We also need dual authentication. But whenever
we use URL.openConnection(), it always returns us weblogic's internal https and
SSL implementation. Since weblogic has no documentation about how to use these
internal classes, such as how to set trusted server certificate, and how to set
client certificate (servlet is a client of another web server). We want to use
jsse, after setting JSSE required system properties, I still get a weblogic's
httpsURLConnection. Can any of you tell me how to resolve this issue?
Thanks.

Yeah, I'm using JSSE now. Here is what I did:
Security.addProvider(new com.sun.net.ssl.internal.ssl.Provide());
Provider prov = new SimpleSecureProvider();
prov.setProperty("SecureRandom.efficient", "test.EfficientSecureRandom");
Security.insertProviderAt(prov, 1);
You don't really need the provider stuff to get the example working. I use it
to get around a quick in JSSE where the random number generator takes 15-30 seconds
to generate a random sequence at start up.
SimpleSecureProvider looks like this:
public class SimpleSecureProvider extends Provider
public SimpleSecureProvider()
super("SimpleSecureProvider-", 1.0, "Hack to enable more efficient random
seed generator");
test.EfficientSecureRandom is bascially an exact copy of Sun's SecureRandom.java
with the only difference that I used my own random number generator.
Anyway, rest of the code you need looks like this:
URL url= new URL("htps://someplace.com");
URLConnection sconnection = url.openConnection();
Do whatever.
I also stored jcert.jar, jnet.jar, jsse.jar in /usr/java/jdk1.3/lib/ext
I think that is everything.
I just noticed that service pack 9 has a security example that does not require
all these jsse hacks. I'm trying to get it to work, but not having much luck.
Anybody got this working right?

We cannot debug your code, but:
Did you try the servlet directly from your browser? Does it work?

HTTPS connection from database

Hi all,
I have to implement https connection from a database with a Web server which requests a client certificate. I have the certificate in the wallet, but UTL_HTTP does not send it to the Web server.
So, is there any way to connect to a Web server which requires a client certificate?

Could you explain how transport protocol influences certificate exchange during SSL session?

Instantiate a bean from within a Servlet

I am attempting to instantiate a bean from within a Servlet. Basically, I would like to set my bean properties from within a central controlling servlet, then call a worker class to take care of my database insert. The worker class would get its values from the bean.
Does this sound reasonable? I'm sure this is quite possible and very easy to pull off, however I can't seem to find a single example. An example would be greatly appreciated.

Hi,
I have read what you have done.
Now in the servlet add something like
HttpSession ses=request.getSession(true);</stro
ses.addAttribute("user","your Bean name");*
in the JSP get this atribute by
session.getAttribute("user");+
Anyway, how have you configured your server? I am using a Bean Class and trying to instantiate in a sevlet. An exception is occuring.
import mypack.User; //it is nicely imported*
//in the doPOST() method
User user=new User();+ //trying to instantiate
it is giving an Exception. Kindly help.

What is the best way to open a HTTPS connection?

What is the best way to open a HTTPS connection and retrieve the content as XML? This is how most of the online API is done nowadays, how can this be done on the iphone SDK?
Thanks

Have a look at the SeismicXML example that comes with the iPhone SDK. It uses http instead of https but it may work for you.
You can also look at the NSURLRequest and NSURLConnection classes.
Enjoy.

Obtain parent directory of WEB-INF from within a servlet

hi to everyone!
i have got a directory containing a WEB-INF directory (with web.xml and all the other stuff necessary). Hoy is it possible to obtain the parent directory of WEB-INF directory FROM WITHIN A SERVLET, put in lib directory?

Does anyone know the meaning of this error?
I try to write a java application using the similar code and it totally works fine(i can connect to the server and obtain the page). Does JSSE support Java Servlet? Or this is the problem of tomcat server? FYI, I'm using

I was just having this issue, after months of error-free ssl behavior, on a new machine i was installing (Note: that I was running the IBM jdk1.3) It turns out that when I was editing the java.security file to know about JCE/JSSE providers i had the providers in the wrong order. The Error causing sequence was:
security.provider.1=com.sun.net.ssl.internal.ssl.Provider
security.provider.2=com.ibm.crypto.provider.IBMJCA
# Extra provider added ibm@33894
security.provider.3=com.ibm.crypto.provider.IBMJCE
# extra provider i added
security.provider.4=sun.security.provider.Sun
The issue disappeared when i changed the order to:
security.provider.1=sun.security.provider.Sun
security.provider.2=com.sun.net.ssl.internal.ssl.Provider
security.provider.3=com.ibm.crypto.provider.IBMJCA
# Extra provider added ibm@33894

How to establish an Https connection from a html client

Hi! I�m totally new to Java so my question is rather"stupid". I have an html page that sends a post to a servlet
<form name="form" action="servlet/ServletLogOn" method="post">
I want to establish an https connection between the client and the servlet. How is it?
Thanks in advance.

Ignore the previous poster's reply - he was obviously mislead by my original post re: JSSE.
How you install an SSL certificate on your webserver is completely dependent on the webserver you are using. Ususally there is some functionality for doing this from the administrative interface - usually involves pasting some text from the CA's (certificate authority, e.g. Verisign) site into a text box and designating a port number for SSL traffic (use 443, it's internet standard). I've actually only done this for Netscape Enterprise Server - you may want to find a forum for users of your webserver to ask for specifics.

Disturbing http connection from ISE to an unknown Internet address

The question is why the ISE is doing this? What is the purpose for this http connection, some kind of "back door" by Cisco?

Liferay is an open source web portal for hosting cloud applications. This is definitely NOT a Cisco back-door to the ISE.

How to transfer the http request from applet to servlet/jsp

I use the JTree component to create a navigation of a website,but i don't
know how to connect the tree's nodes with the jsp/servlet.
I mean how to transfer the http request from the applet to a jsp.
I use the "<frameset>" mark which will divide the web browse into 2 blocks.
The left side is Applet,and the right side is the linked jsp page.
what I say is as the weblogic console layout.
who can help me!!!
Thank You!

Can I use SimpleFdkCredential() from within a servlet?

I have a test program that logs in to content DB using SimpleFdkCredential, and works perfectly well run from the main() method of a Java class from within JDeveloper. When I try to login the same way from within the doGet() method of a servlet, doGet() hangs on the call to ManagersFactory.login() using the same SimpleFdkCredential that works in-process. The login() call doesn't throw any exceptions, it just sits there waiting[I presume], and never returns.
Is it necessary to use S2SFdkCredential for any authentication that originates from a servlet invocation? It seems that SimpleFdkCredential should work in this instance as well.
Thanks.

Can you check the Content DB http node log (application.log) with debug log level set, to see if the request from the servlet for the RemoteLoginManager Web Service was received?
I would also check that all libraries are present/accessible from servlet - and that there are no conflicts with existing libraries.
Also, check the servlet log for anything strange.
Finally, you could try remote debugging of your servlet .. e.g -Xdebug java option.
