Java HTTP Connection Filed - It's a DNS problem

Hello all,
my first post is for talking about this infamuos error of java.
When i try to view a page that use Java for one of it's applet, the applet doesn't work and Java console report among other errors:
Caused by: java.io.IOException: open HTTP connection failed.
     at sun.applet.AppletClassLoader.getBytes(Unknown Source)
     at sun.applet.AppletClassLoader.access$100(Unknown Source)
     at sun.applet.AppletClassLoader$1.run(Unknown Source)
     at java.security.AccessController.doPrivileged(Native Method)
     ... 10 more
But if i nslookup the ip of the address and i try to download the applet by this way... all go fine.
I tryed also Java Web Start -> same errors, but referred to URL Resource downloading.
I's clearly that something in java or outside java is avoiding the NS resolution.
I disabled all the firewalls, all the antyspyware... ALL...
I try also Safe Mode with networking... eheh...
nothing... java doesn't do NS.
It's a big bug... i use the latest java 1.05_05.
I'm not behind a proxy, i use firfox 1.0.7 and ie 6.0 sp2.. and windows xp... All give the same errors.
If someone managed the error please could help me? I read the other posts but it seems to me this is a open bug.
Goodbye,
eTomm

It's not difficult understand the topic.
The actual DNS resolution implementation of Java is faulty.
It's the ONLY service in my Windows machine that couldn't do a correct DNS resolution, stand alone application, Internet Explorer and Mozzilla web pages with applet-
If i use IPs all go fine... when i use domain java fail.
ALL java... non only applet. Also Java Web Start fail.
I controlled proxy, there isn't. i say to java to do a direct connect.
The only thing in my net configuration of strange is the router, a zyxel 660hw... nothing else... my pc work fine with all the rest of the programs that use IPs. Only java is faulty.

  • Safari not responding when HTTPS connections are unavailable

    I'm using a 13" MBP with 10.7.2 installed, which is setup to sync calendar, address and bookmarks with iCloud. Since last week I've constantly encounter a problem that my Safari 5.1.1 would keep crashing, and I had to delete the ~/Library/Safari/extensions folder to get it back to work.
    This situation happened whenever I've switch to wireless connection. In my office we've setup a limited wireless environment that all HTTP/HTTPS connections will be redirected through a proxy. Since last week the proxy server was malfunctioned. All HTTP connections are proceeded normally, but all HTTPS connections will be suspended. I'm not sure but I suspect it's the main reason for the crashing problem.
    The syndromes are:
    1. When I left Safari open, unplug the ethernet, and turn-on WiFi, everythings goes on normally, until I open an HTTPS web page, for example, https://www.icloud.com. Of course that HTTPS URL will not load, since our proxy is broken; but the connection itself will NOT timeout. I've tried to leave it connecting for 10 minuntes, and it's still there.
    2. The statement above may due to a glitch in our proxy server and I can understand that. But the problem is: after I tried to open an HTTPS connection, the Safari will refuse to open any other URLs, including normal HTTP connections. It will just keep "connecting". Meanwhile the FireFox and Chrome can load these HTTP pages normally.
    3. If I quit Safari in this situation, Safari will not be able to re-launce: the icon will keep bumping on the dock. I have to force quit Safari and delete extensions folder, so that it can be launched again. But even after Safari re-launced, it still refused to load HTTP pages.
    4. Neither reconnecting WiFi, relogin, or switching back to ethernet can fix the problem. I have to restart the whole system to get it back to normal.
    It seemed to me that some Safari-related process will keep in the system after Safari is quited. And that process may keep the inactivated HTTPS connections alive in its TCP pool, and blocked all sequence connections, including the iCloud synchronization. And while I force-quit Safari, the extensions.plist file is damaged. That's the only plausible explanation to this situation.
    I'm sure this situation is introduced after 10.7.2: it's not the first time our proxy server breakdown, but I've never have this problem before.

    I've done some detailed test and now I can give a conclusion:
    1. It's confirmed that sequence HTTPS connection will be blocked in Safari and Google Chrome after a failure HTTPS connection (due to proxy). And rebooting is the only way to recover connections.
    2. My previous observation is wrong: this is NOT a system wide problem. FireFox is not affected. FireFox will return to normal and all sequence HTTPS connection can be proceeded without any problem when I reconnect to a valid network connection (i.e. ethernet), while the Safari and Google Chrome remained being blocked. And DropBox is NOT affected as well.
    3. None of the solutions mentioned in other threads can solve this problem. Checking the "Auto proxy discovery" does not help. Delete ~/Library/Preferences/com.apple.security.revocation.plistfile does not help. Clean Keychain does not help either. I've created another account for testing.
    4. It's apparently something related to some system built-in network services. Since the FireFox and DropBox both gets its' own Proxy implementation, while Safari and Google Chrome will take the system settings. It's also worth noting that the POP3-SSL connection in Mail.app is also blocked after a failure HTTPS connection.
    Currently the ONLY valid solution is using FireFox instead.

  • HTTP Connection for Solution manager

    Dear Experts,
    SAP support team asked to create a http connection for solution manager for service check.We already created a R/3 connection for solution manager.why they are asking for HTTP connection? Really they required HTTP connection ?,Is they are any problem with this type of connections.What are the transaction codes which are not run in SAP GUI. Please clarify my doubts.
    Thanks and regards,
    Patan Thavaheer.

    Hi Patan,
    Solution Manager transaction codes open in http browser. You can check the behaviour yourself by making a login to solution manager and execute transaction code solman_setup.
    For SAP support to open http browser within remote support, they need to have http connection opened along with HTTP url maintained.
    Refer to the SAP help link above for the procedure.
    Hope this helps.
    Regards,
    Deepak Kori

  • Making https: connection from java code loaded into Oracle 8i database

    A bit of a blast from the past, really, as 8i provides a JVM at 1.2.2.
    I need to provide an PL/SQL function which accesses a RESTful web service requiring https connection. Got the call working under 1.2 locally without much trouble using:
    static {
            System.setProperty("java.protocol.handler.pkgs",
                    "com.sun.net.ssl.internal.www.protocol");
            Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
        }The trick is to get the Oracle database to run the code internally. What libraries do I need where? I get an extremely unhelpful NoClassDefFoundError, without mention of the offending class.
    By doing loadjava with jcert.jar,. jnet.jar and jsse.jar (the libraries I'm using with the test program) I can get loadjava to accept and allegedly resolve the class.

    Well, sadly look at the colour scheme.Yeah, sarcastic was I. The NoClassDef error seriously doesn't give a class name? I find it astonishing that any implementation would be that stupid.Seriously. The strange thing is that before I got to the NoClassDefFound I had a Initialization error (until I added a security rule for setting the Provider) and for that I got a full stack trace (in an obscure trace file, granted).

    ==================================
    The applet is in the same directory as the ASP. It is a NT 4 (SP6) server. The applets loaded and ran fine with jdk1.3. Do I need to do something different in my ASP, or IIS setup to allow java applet HTTP connection in JDK1.4?
    Thanks!

    I have the exact same problem but have yet to find a solution.
    It works fine in 1.3 but fails occasionally in 1.4. If I refresh the browser several times it eventually
    loads.

  • Java.io.IOExcetion :open HTTP Connection Failed

    Hi Everybody,
    I'm getting the java.io.IOExcetion :open HTTP Connection Failed error when I'm trying run a html page with an embedded Applet in it.
    We are having a proxy server and all our network traffic have to be done through proxy.
    But in Browser we give exemption to local host.
    When I run the html file outside JDeveloper keeping it in the same directory in which the Applets class file is : I'm getting the Applet running.
    But If I run the html page From JDeveloper , I'm getting the above said error.
    My JRE is configured to use Browser settings and the browser is set to use the proxy.
    Why are applets not able to connnect to the sever?
    How to make Jdeveloper connect to proxy?
    Thanking you for the answer?

    Hi ,
    Even Iam getting same error error message is as follows. I tried setting codebase to appropriately but still Iam getting the same error. I searched all the forums they were also talking abt proxy setting does has any idea is that is also one of the reason. Please let me know how can I fix this problem. same application works fine with MSJVM but not with SUN JVM 1.4.2_07.
    Waiting for reply....

    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
    security.provider.4=com.ibm.crypto.provider.IBMJCE
    hope that helps!

  • 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.
    Xinshi

    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?

    See if this works,
    1. Add the 'j2ee.jar' to CALSSPATH in weblogic startup script.
    2. Set the property SSLHandlerEnabled flase in config.xml

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

  • 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, <b>but how do I create the keystore object</b>? 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".
