1. import java.net.Authenticator;
2.
3. class ProxyAuthenticator extends Authenticator {
4.
5. private String user, password;
6.
7. public ProxyAuthenticator(String user, String password) {
8. this.user = user;
9. this.password = password;
10. }
11.
12. protected PasswordAuthentication getPasswordAuthentication() {
13. return new PasswordAuthentication(user, password.toCharArray());
14. }
15. }

I have implemented above.

I want to verify that the provided username and password are correct for that proxy,
When password authorization is not needed means getPasswordAuthentication() will not call at this time.
I need this to ensure the username and password are correct when they needed means when getPasswordAuthentication() will call.

Thank you alot. Your solution worked perfectly well. It is accepted by the proxy without any hitches.

Thank you very much! It worked!

Yes it worked for me.

But the problem is that its caching the credentials which are provided for the first call and is not picking up the new credentials.

Please suggest how we can reset the JVM cache for java.net.Authenticator object reference.

Thanks

Is there any way to setting proxy config to particular class? Or else, is there any way to setting proxy config to jax-ws? I don't want to touch global jvm config(
System.setProperty("http.proxyHost", "proxy host");).
Because I concern it will effect to all other classes which are connecting to network things(various host and ip which are actually local). I don't want to exclude em by "http.nonProxyHosts" also. Is there any way? Thanks in adv for help.

NO, it works without that.

Do you need to set any SecurityManager in order for
Authenticator.setDefault(new ProxyAuthenticator("user", "password"));
to work?

is there a way , where you can set proxyUser, and proxyPassword, without setting property in System class.
Because i have this issue on Weblogic, not able to set property in system class(i mean the system.setProperty has no effect)
I tried apach HttpClient as well, it doesnot support NTLM.

I think it should, though I never tried it for ftp protocol hence no definitive answer ;-)

Would this work for ftp.proxy* as well?

This example uses System properties. This is not ideal for web applications--as this system property will affect the complete JVM running the web application.

We ran into issues when we deployed two web-applications, one of which connected to a local HTTP server, and the other using proxy connected to a internet site. When we set the system properties, the one requiring local connection was also trying to go through the proxy.

Finally we used Apache HTTP Client:

http://hc.apache.org/httpcomponents-client/index.html

This has a neat proxy authentication implementation.

I am using weblogic 9.2 to run my application.
