Ssl comms in applet to stunnel server

I'm using j2sdk1.4.2_08 in windows xp.
I'm trying to do SSL comms in an applet to a 'stunnel' server.
I followed all the useful directions I could find,
but I keep getting 'No trusted certificate found' at the SSLStartHandshake statement.
Running as an application I have no trouble at all, everything works fine.
Which java.security permissions (check permission), if any, apply and have to be explicitly set in the applet code when using the javax.net.ssl.* in an applet?
I followed these steps:
-generate public and private key pair with the public key in a self-signed certificate
-signed the JAR File containing the applet's class
-exported the public key certificate
-imported that certificate as a trusted certificate in to a 'user' keystore with alias 'sslalias'
-created a java.policy file using that 'user' keystore granting all permissions to
the jar signed by 'sslalias'
- started appletviewer with this java.policy file.
I still keep getting the same 'No trusted certificate found' problem
Tried several other scenarios, nothing works. Only the application version
works.
I have wasted an enormous amount of time trying to get this to work and now I'm at
the end of my thether.
Any help is appreciated!!

can it be that the username and password passed to SQL server are wrong or mistyped? if not, it can be that the user trying to access the database doesn't have appropriate permissions.

SSL Sockets and Applets

Overview: I need to make an Applet communicate with a server using an SSLSocket and I can't figure out how to include a truststore when running the applet in a web browser.
Background:
The applet communicates perfectly using regular non-secure sockets. I am now porting it to use secure sockets (SSLSocket, SSLServerSocket from JSSE).
The applet communicates perfectly using secure sockets when run in appletviewer with the truststore file in the classpath. I have specified the appropriate truststore properties in the Applet as follows:
     System.setProperty("javax.net.ssl.trustStore", "truststore");
     System.setProperty("javax.net.ssl.trustStorePassword", "password");
This works when run using appletviewer when the "truststore" file is in the classpath, and now I need to make it work in a web browser.
Problem: How do I include the "truststore" file with an Applet?
I have tried including it in the .jar file, which seems conceptually similar to including it in the classpath, which worked with appletviewer. However, including it with the .jar file doesn't work. The exception I get is:
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: No trusted certificate found
Any ideas on how I can include the truststore file or suggestions on another approach that will accomplish the same thing?
Thanks a lot!

Hi,
I'm in the same boat.
Thought I had a solution. I'm running an applet that opens an SSL socket back to the web server it came from
URL url = new URL("https://" + baseUrl);
URLConnection connection = url.openConnection();
connection.setDoOutput(true);
connection.setDoInput(true);
-then just open streams. Info related to this at
http://java.sun.com/products/plugin/1.3/docs/https.html
Essentially, I'm taking advantage of the SSL connection made during the initial web page/applet load ([SSL_RSA_WITH_RC4_128_MD5 is what my HTTPS server wanted )
The down side is that GET/POST are the only actions supported (refer to the link).
I'm looking for a solution that specifies HOW I ACCESS my local browser's security so I don't get
j'avax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: No trusted certificate found'.
Hope someone replies...

Referencing a "locally installed" Java applet from a server-based HTML page

How does one reference a "locally installed" Java applet from a server-based HTML page (i.e. via the applet, object, or embed tags)? I have seen references in documentation that this is possible, but I have not seen any examples. I have tried a few things, but nothing seems to be working.
Some background...
I'm working on a web site that aggregates Internet video. For many users, I would like the site to work "without" requiring Java to be installed (or any prompts, etc.). This version of the site allows users to stream videos directly over the Internet and does not require any sort of access to the local system.
However, in addition, I have a download manager that can be installed on the local system. Currently, it's a Windows-based "service" that is always running in the background, downloading files, etc. (with plans to later support other OSes).
My dilemma is trying to communicate between my web site running in the local browser (executing JavaScript code) and the download manager. I call this component the "gateway". I need the gateway to be able to do the following:
1) Pass user credentials from the web browser UI to the download manager (so it can communicate with my servers).
2) Check the status of downloaded videos
3) Launch a local media player (such as Windows Media, QuickTime, etc.) (or perhaps tell the download manager to launch the media player).
Under Windows XP, I have an ActiveX control that can do these things. It communicates with the download manager via reading/writing to a shared XML configuration file.
Unfortunately, under Vista and IE7 Protected Mode, ActiveX controls have become very restricted and my gateway no longer works. As such, I am looking at using Java for the gateway (also giving me the additional benefits of supporting additional browsers and OSes).
From my understanding, I believe I can created a "face-less" Java applet, whose methods can be called from JavaScript. Ideally, I'm thinking I could install the applet onto the local system at the same time the download manager is installed. This would give the applet the security permissions it needs to communicate with the download manager.
Thanks for any help and suggestions!

Hi,
Put the .jar file and the .class file in the path mentioned in one of the aliases in the plsql.conf file like /images or create
a seperate directory and create an alias like /applets "path" in the plsql.conf file.
<html>
<body>
<applet code=com.chartapplet.chart.BarChartApplet
codebase=/applets/
archive=/applets/chart.jar width=300 height=200>
<param name=background value="white">

Distributing Applet in Web Server

Hello,
I am in the process of creating a new web server. Although, I have found an error that when you retrieve applets from my server they don't work, whereas they do normally if locally. The file is send exactly as it is through a binary transfer. I am wondering if Java has any sort of header information or something that must be attached to the transfer while being sent or if anyone has encountered this before.
Thank you

Well, as I said I am creating a web server. It works by when it recieves a request for a file, it opens the file in binary mode and transfers it as binary to the program that requested it (the web browser).
I have created an applet that works fine when it is run locally on my desktop, but when I try to run it through my web server by setting the codebase equal to "http://localhost/" the applet will not run. It returns a NullPointerException and I am not sure why.
Thank you for your help

Directory selection for Discoverer applet on HTTP Server

Hi
I installed Discoverer 3i on NT SP4
My http server is OAS 4.0.8.1
I tried single machine install and while providing the directory for Discoverer applet on HTTP Server i gave a directory which is not root directory for OAS
How do i set virtual path so that discoverer may be configured in my http server (OAS)
What are the steps?
Thanks
null

Go to the Directories section in OAS. You will already have virtual directories set for OAS. Use one of these as an example.

Two-Way SSL does not work until "Use Server Certs" is selected on client

We have a web service application and a client application. Both applications are deployed in WebLogic 10.3. The web service application is secured by Two-Way SSL. When the client attempts to access the service, we got the following error logs on the server side:
<Dec 8, 2009 3:25:42 PM EST> <Warning> <Security> <BEA-090508> <Certificate chain received from ... was incomplete.>
CertPathTrustManagerUtils.certificateCallback: certPathValStype = 0
CertPathTrustManagerUtils.certificateCallback: validateErr = 4
CertPathTrustManagerUtils.certificateCallback: returning false because of built-in SSL validation errors
We got the same error even if the WebLogic 10.3 domain on the client side uses the same identity and trust keystores as the server side.
The problem was solved when we selected Environment -> Servers -> <server> -> SSL, expanded "Advanced" and selected "Use Server Certs". Could anyone tell me what "Use Server Certs" does to make the difference?
Another question is how we can invoke this web service in a Java application since "Use Server Certs" solution only works for web application deployed in weblogic.

"Use Server Certs" means that a client application running within Weblogic will use the WL managed server's identity certificate as its client certificate. Otherwise, the client application is responsible for selecting the keystore, and presenting the certificate as part of the handshake.
This is a great feature in 9 & 10; client SSL was much more difficult in WL 8.
If you are using a standalone client application to invoke anything over 2-way SSL, you are responsible for presenting the certificate. For instance, if you invoke the page from your browser, your browser can maintain client certificates and you'll get a popup to select which cert to use.

Send data from applet to web server

Hi,
I want to send data(event notification) to resource through web server using url.
Like,As long as perticular action or event is occuring I am sending that message to url.
I reffered Sevlet theory uses HTTPMessage,but I am confused how should start and what would be feasible?
Even when I run my code I am not finding browser.How should I place an applet in web server page?

Hi
I agree usage of HttpClient is a better and a simple method.
But If your Application Requirements are Simple you may go by using URL & URLconnection Objects in java.net package.
Just to Add In You Can Checkout the links given below to have a better understanding of how the communication works...

SSL authentication in Applet, the next step?

Hi,
In the following code:
     private RssReader rssReader;
     private void createFeed() {
          rssReader = new RssReader("https://{username}:{password}@{domain}/mymon/index.php?{anaction}=rss.showrss&server_id=&ident=&statusnr=2&block=7&wwwauth=1");

I have been reading the 'JSSE Reference Guide for Java SE 6' document (http://java.sun.com/javase/6/docs/technotes/guides/security/jsse/JSSERefGuide.html).
What I can't seem to wrap my head around is what I need to do in a client (the Applet mentioned in the previous post) to authenticate. I know it should be possible, as there is a getNeedClientAuth() (Returns true if the socket will require client authentication) method in javax.net.ssl.SSLSocket.
So, through what hoop do I need to jump through to be able to authenticate a user in the Applet?
Background:
I want to read the contents of a RSS Feed coming from a https page. The user of the Applet needs to authenticate him/herself using his/her username and password.

Applet hangs web server when upgrading from 1.6 to 1.7

I've got a client-side printing application which works fine on 1.6 and fails on 1.7 where it essentially hang the server on the connect option to the server and loading the jar file. Specifics:
PC Client running windows 7 x64
Browser versions IE9, IE10, Firefox 17.0.1 (PC-client) all fail
Client PC has latest Java 1.7.0 10-b 18 installed
Web server is Apache2.4.3 x64 running on Windows 2008 Server R2 through the network
Jar file is signed and the certificate is loaded
Apache server is sitting on another server through a network connection. Backrev java to 1.6 and it passes. I've specified the -Djava.net.prefIPv4Stack=true option in the applet call but it doesn't fix the issue.
The java console loads but then hangs on the connecting portion:

What is most irritating is that a local instance for debugging (i.e. apache2.4.3 x64) running locally and running the application on the same machine) passes perfectly so it appears that it involves a network connection rather than a localhost operation.
I noticed on a good connection the server returns with ResponseCode 304. I do not see that line in the log on the failing applet load. Apache logs set at debug show no errors even though the operation hangs the server.
Anyone got any ideas on how to debug and resolve this?
-Thanks

More information:
Installed jre.1.6.37 (x32 version) along with 1.7.10 (x32 version) and the applet loads. Installed 1.7.10 (x32 version) only on the windows 7 x64 client fails. I've done both the x-java-applet method and the JNLP method and both hang. The JNLP j2se version is set to "1.6+" so in theory 1.7 should jre should work fine without a 1.6.37 loaded.
I've got wireshark dumps that I'm analyzing and noticed that there two OCSP responses (successful) but nothing after that, specifically where it hangs. Any ideas on how to debug this further?

Passing data b/w applet and apache server

Hi all,
I have an application that runs in the JApplet.I have to pass data b/w server and applet.The
datas are brought from the server using php to the browser and passed to applet using param
tags.
1.Is it possible to set value for the param tag from applet?
2.How to retrieve data from the param tag to the applet in the form of an array.
In the getParameter it is required to specify the param name.
Is it possible to retrieve data from param tag similar to that of getting data from command
line arguments array.

Hi all,

1.Is it possible to set value for the param tag from
applet?Why do you ever want to do it? It sounds like setting arguments passed to a program's main method from command line after the main method has been invoked. It is possible though to dynamically set any values for any applet params using php before the applet gets loaded to the browser window as you generate an html file on the server side.
2.How to retrieve data from the param tag to the
applet in the form of an array.
In the getParameter it is required to specify the
param name.
Is it possible to retrieve data from param tag similar
to that of getting data from command
line arguments array.You can use some naming/numbering convention for your params. For example settings1, settings2 ... Then you can loop in your code retrieving the values like getParameter("settings" + i) checking to see that it is not null or empty.
However, if you don't want to reload the applet (together with the page) just to get some new data from the server, you can establish a tcp/ip connection as elchaschab recommended.
Cheers!

SSL certificate selection weirdness in iCal server config

I have a wildcard certificate installed via the certificate manager on a 10.5 server, and it's working perfectly with dynamic virtual hosts in apache, with mail via POP3, IMAP and SMTP. However, something odd happens in iCal admin. The certificate popup menu contains:
No certificate
Custom Configuration...
*.example.com
Default
Manage Certificates...
So, I select my installed certificate and click save. The certificate popup immediately changes to "Custom Configuration..." and I'm asked whether I want to restart iCal for the change, which I accept.
Connections to iCal work when SSL is off, but if I use an SSL URL like:
https://ical.example.com:8443/principals/users/myname/
I get this error:
Account information not found
Unexpected secure name resolution error (code -9844). The server name ical.example.com may be incorrect.
When SSL is on, non-secure requests just don't respond.
Nothing appears in the iCal server log.
If I select the custom config from the certificate menu, it just shows me the same certificate and key path that the certificate manager does, so I've no idea why it's reverting in the menu when it doesn't in other service admin panels.
The necessary firewall ports are open, though I've tried it with the firewall off just to check.
I've heard that if DNS doesn't have matching forward and reverse resolution the first time iCal is configured, it can screw things up, and I did that, but I've no idea what effect it has.
Any ideas?

Sounds like you're looking at the access log.
The error log is the one that would have the funny business listed.
Try switching logs through the dropdown at the bottom of the server-admin ical logs screen.
When I enable SSL and try to visit the page via https://host:8443/ the error log for the ical service shows a number of processes dying with the following error: (replaced real date/time to save time!)
pydir] date/time marking host ('127.0.0.1', 8444) down ([Failure instance: Traceback (failure with no frames): <class 'twisted.internet.error.ConnectionRefusedError'>: Connection was refused by other side: 61: Connection Refused.
pydir] date/time ])
pydir] date/time retrying with ('127.0.0.1', 8445)
Then it goes on to repeat the error with 8445 and so on until it reaches 8451. (they look like PID numbers.. not port numbers. see below.) Afterwards I receive:
pydir] date/time no working servers, manager -> aggressive
pydir] date/time re-adding ('127.0.0.1', 8449) automatically

How do I communicate a Java Card applet with a server?

I'm new to Java and Java Card and currently developing a smart card system. I'm not sure what to use on my applet or server, JCSystem or SecureConnection or something else?
If I'm writing a server application, then how do I install it so that I can simulate it with cjre?
Thanks in advance.
p/s: Connection is using TSL.

The flow is like this:
Java Card --> POS terminal -> Server
Yes. I'm using JC3.
Here's what I've achieved so far using SocketConnection
SocketConnection sc = (SocketConnection) Connector.open("socket://localhost:50007");
InputStream is = sc.openInputStream();
OutputStream os = sc.openOutputStream();
os.write("Hello world!".getBytes());
is.read(buffer);
os.close();
is.close();
sc.close(); Edited by: andirady on Dec 4, 2012 11:59 PM
