Ice.SecurityException IceSSL: handshake error

salageri

Hi

I am trying to integrate Ice (using Ice3.2) from Tomcat and https but when I create a proxy I get below errors.

I am able to do https://localhost:8443 but when I create a IceProxy Tomcat crashes and stops fails.This works very well from java application outside tomcat.I have all the certificates at the right path.

This is my connector string for https
and this is how i call NetServicesProxy =
IceProxyFactory.getNetServicesProxy(communicator);


<Connector
port="8443"
protocol="org.apache.coyote.http11.Http11NioProtocol" SSLEnabled="true"
maxThreads="150"
keystoreFile="C:\Program Files\Apache Software Foundation\Tomcat 7.0\conf\bng.ads.my.net.p12"
keystorePass="ererer!"
keystoreType="PKCS12"
scheme="https"
secure="true"
clientAuth="false"
sslProtocol="TLS"
/>


These are the errors.

Hi,

If I understand things correctly, you are attempting to make an Ice invocation over SSL from within a Tomcat servlet, and the SSL handshake fails with a "No appropriate protocol" message. The most likely reason for this is a configuration problem, either in your servlet or in the remote Ice server. The fact that you're using HTTPS to communicate with the Tomcat server should not have any impact on the Ice activities of your servlet.

If you're still having trouble, please post the IceSSL configuration properties being used by your servlet and the remote server.

Best regards,
Mark

As a first step, I suggest changing the following properties in your servlet's configuration:

Ice.Trace.Network=3
Ice.Trace.Protocol=1

Run your servlet again, capture the log file output, and attach it here. My goal is to find out which endpoint the servlet is attempting to use.

Hi,

Thanks for posting the log information.

My first suggestion is to verify that the servers shown in these endpoints are in fact using SSL (and not TCP):

[Network: trying to establish ssl connection to 141.124.212.106:10205 ]
[Network: trying to establish ssl connection to 141.124.212.105:10205 ]
[Network: trying to establish ssl connection to 141.124.212.104:10205 ]

Note that the endpoint settings for these servers is probably stored in IceGrid.

Second, since you stated in your original message that a standalone (non-Tomcat) application works correctly, the goal should be to discover what the differences are between the standalone and servlet cases. For example, are you absolutely sure that the servlet is using the configuration properties in the file that you attached? One way to verify this is to add the following diagnostic code to your servlet:

java.util.Map m = communicator.getProperties().getPropertiesForPrefix("");
Ice.Logger l = communicator.getLogger();
java.util.Iterator i = m.entrySet().iterator();
while(i.hasNext())
{
    java.util.Map.Entry e = (java.util.Map.Entry)i.next();
    l.print(e.getKey().toString() + " = " + e.getValue().toString());
}

This code simply dumps the contents of the communicator's properties. Once you have this output, I would compare it against the properties (especially the IceSSL properties) that you expect it to be using.

Regards,
Mark

Thanks Mark.

Yes I am using an IceGrid and I have jar file which I call outside tomcat and inside tomcat.And all configurations are same.Only thing outside Tomcat it works.

I have made the changes you mentioned and attaching the logs from IceStdErrorOutsideTomcat and
IceStdErrorFromServletTomcat

Also Attaching the file which I am using for Testing

Please post your version information for the following:

• JVM used for the standalone (non-Tomcat) program
• JVM used for Tomcat
• Tomcat version

Thanks,
Mark

mes

Our suspicion is that Tomcat's SSL configuration is interfering with your servlet's SSL connection. You could try temporarily disabling the use of HTTPS in Tomcat (i.e., use HTTP instead) to see if that eliminates the servlet's failure.

Another suggestion: run the standalone program with the JVM option -Djavax.net.debug=all, and then run Tomcat with the same option. This will probably generate a lot of output, especially for Tomcat, but it should provide some useful information about the protocols and ciphersuites that the JVM is using.

Ice.SecurityException IceSSL: handshake error

Hi Mark

I switched to https when I had the same handshake issue with http .Anyway I have switched over to http based on your request.

I see that after adding debug -Djavax.net.debug=all outside and inside(tomcat).

My jvm is 1.6.024 for both outside and Inside tomcat. And I am running Tomcat_6 Apache Tomcat 6.0.18 Server - Apache Tomcat - Welcome!

Anyway attaching all the files for your clarity

The IceStdout is the one which gives the certifcate output.

Attaching Inside_Tomcat_IceStdOut and OutSide-Tomcat and also http_Tomcat_Std_out for reference

Yes outside Tomcat the IceStdOut output produced is more as it works there.

Thanks

Ice.SecurityException IceSSL: handshake error

Based on some findings I also tried changing in jre/lib/java.security by adding these lines but that to had no effect

security.provider.1=sun.security.provider.Sun
security.provider.2=com.sun.net.ssl.internal.ssl.Provider

I restarted tomcat after the above.

I would like to know if we need any modifications in Ice code for this

Hi,

I set up a Tomcat server using the following environment:

* Windows 7 (32-bit)
* apache-tomcat-6.0.36
* jdk1.6.0_25

I created a simple servlet version of the client from the Ice "hello" demo:

}

The config.client file contains:

Hello.Proxy=hello:ssl -p 10001
Ice.Plugin.IceSSL=IceSSL.PluginFactory
Ice.ThreadPerConnection=1
IceSSL.DefaultDir=C:/hp
IceSSL.Keystore=client.jks
IceSSL.Password=password
IceSSL.Truststore=certs.jks
IceSSL.Ciphers=NONE (RSA.*AES_128) !(EXPORT)

I deployed the webapp, started the Ice "hello" server, and used the browser to access the servlet. The servlet successfully connected to the server via SSL and invoked the sayHello operation without problems.

I can provide an archive of the servlet files if you'd like to see them.

My first suggestion is to try your servlet without defining the IceSSL.Ciphers property, just to see if that makes a difference.

My second suggestion would be to start over with a simple servlet example like mine and slowly modify it to more closely resemble your final version. If you can provide me with a small (but complete) example that reproduces the problem, I'd be happy to take a look at it.

Thanks Mark,

You are very much right.Disabling the IceSSL.CIPHERS resolves the issue.I am able to invoke it perfecly now.


Thanks again

Hi,

I set up a Tomcat server using the following environment:

* Windows 7 (32-bit)
* apache-tomcat-6.0.36
* jdk1.6.0_25

I created a simple servlet version of the client from the Ice "hello" demo:

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class HelloWorld extends HttpServlet
{
    public void doGet(HttpServletRequest request, HttpServletResponse response)
        throws IOException, ServletException
    {
        response.setContentType("text/html");
        PrintWriter out = response.getWriter();
        out.println("<html>");
        out.println("<head>");
        out.println("<title>Hello World!</title>");
        out.println("</head>");
        out.println("<body>");
        try
        {
            Ice.InitializationData id = new Ice.InitializationData();
            id.properties = Ice.Util.createProperties();
            id.properties.load("C:/hp/config.client");
            Ice.Communicator c = Ice.Util.initialize(id);
            Ice.ObjectPrx o = c.propertyToProxy("Hello.Proxy");
            Demo.HelloPrx h = Demo.HelloPrxHelper.uncheckedCast(o);
            h.sayHello(0);
            c.destroy();
            out.println("<h1>Hello World!</h1>");
        }
        catch(Exception ex)
        {
            ex.printStackTrace(out);
        }
        out.println("</body>");
        out.println("</html>");
    }
}

The config.client file contains:

Hello.Proxy=hello:ssl -p 10001
Ice.Plugin.IceSSL=IceSSL.PluginFactory
Ice.ThreadPerConnection=1
IceSSL.DefaultDir=C:/hp
IceSSL.Keystore=client.jks

Hi,

Glad to hear that it's working for you now.

I suspect what's happening is that Tomcat (somehow) is limiting the available ciphers, or perhaps using an entirely different set of ciphers, than what you get outside of Tomcat. If you run your standalone client and your servlet with IceSSL.Trace.Security=1, Ice will log the list of available ciphers. Your setting for IceSSL.Ciphers was apparently too restrictive in Tomcat and eliminated all possibilities. Once you know what ciphers are available, you can enable IceSSL.Ciphers with an appropriate value.

Hi,

Well I see that TLS_RSA_WITH_AES_256 Cipher suite or any other Cipher suite is not diplayed from Tomcat IceStdout but gets displayed outside tomcat.

Looks like disabling it makes a possible workaround.

Also
openssl ciphers -v 'ALL:!ADH:@STRENGTH' doesnot indicate the above SSL and so bypassing it makes sense.
