SSO for Java not working

Hi,
We have configured the Secure login Server and enabled the SPNEGO. We are getting the certificates and able to fully get the features of X.509 and Kerberos functionallity in ABAP.
However in the case of JAVA stack it is not taking the windows authentication and logging in instead prompting to enter the user name and password.
Any help on this is appreciated.

Hi,
Following is the log trace. I am using AS JAVA 7.4. From security trouble shooting wizard, i pulled the trace.

Hi,
I had a similar problem with my Dell Latitude E4310, and apparently also the E6410, E6510.
The solution for me was to add the following line to /etc/modprobe.d/modprobe.conf:
options snd-hda-intel model=dell-s14
I tried that, unfortunately it does not work with this chipset. I do get a different set of channels though but it still cannot record anything. Maybe this chipset is too "new" for alsa. The latest release dates back from the end of January. Support for it is explicitly stated in the changelog to 1.0.24 but perhaps the recording part of it slipped through the cracks. ALSA bug tracking system seems quite closed.

In sm21, I cannot see any logs from the AS. I can only see the ones from CI.
Any ideas how to solve this issue ?
Anything is welcomed,

ICloud for pc not working tried everything

iCloud for pc not working tried everything ( uninstall - reinstall - delete files - old versions ) nothing helps it just downloads a couple of photos and off again my iPhone uploads perfectly as all the pics goes to the iPad seamlessly, Please Help i'm on windows 8.1 x64, Thanks

I think that the card reader may in fact be defective, but it just doesn't make sense if I have already used it fine before. I've tried everything on this Apple support page, thank you though.
Does anyone have any suggestions?

Skype 6.3 upgrade for Mac not working

[Topic title updated by moderator to be more descriptive. Original topic title was: "Skype upgrade for Mac not working"]
BE WARNED - just because you are being asked to upgrade your Skype, it does not mean it will work on your machine. I am a fairly regular user of Skype and this morning was unable to log-in, being told that I needed to upgrade. I did so to 6.3.0.602 but I was unable to log-in once the software had downloaded. After some research on the forums and finally a text chat with Support, I was told that Skype 6.3.0.602 requires a Mac OSX of 10.9 or above - I have 10.5.8
"So what can I do", I asked the tech support. The answer is nothing (unless I get new OS X software) - there is no Skype software programme that supports my operating system and no timeframe for when it might be available.
Huh? That's right. It's just not available. So for now, users with less than OS X 10.9 will be unable to use Skype when they are instructed to upgrade. It really doesn't make sense. But just so you know....

Please look at the top of the community page, and you will find a box "Search:". Write your problem here "Upgrade not working" and see what crops up. Most likely you will be taken somewher like here: http://community.skype.com/t5/Mac/quot-We-ve-signed-you-out-because-your-using-an-outdated-version/m...
Here you will read that the latest versions of Skype will not work on some of the versions of MacOS, and that PPC requires one version, Leopard another, Snow leopard another, Mountain Lion another. They are indoctrinated with a stamp in their forehead to enforce their congregation of true believers to install the latest with all "security fixes" or death is looming. They are not used to software that is 2 years old.
So, with Mac, we have different operating systems and different sets of libraries - and things may go belly up if you upgrade - a OS feature is done differently, a libary has been placed inside the OS, and is no longer needed - and if you try to use it, you will be trapped.
Install the latest version that works for your Mac, and make sure to freeze this. Update the "info.plist" file and tell Skype that you use their latest should they pry. As long as it works, do not change anything!
And make the change to stop Skype from checking every time you start.

Create a new profile as a test to check if your current profile is causing the problems
See [[Basic Troubleshooting#Make_a_new_profile|Basic Troubleshooting: Make a new profile]]
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins"

SSO to R3 not working after system copy

Hi Experts,
Recently our QA R3 client XXX was deleted and the whole system was rebuild using system copy of client ZZZ of R3 production. Now we had to reconfigure the SSO between portal and QA R3 with the new client.
But it is not working. It was found that the QA R3's own self signed certificate shows CN=ERP (same as R3 Prod) and not ERU as it should have been. We changed the CN value to ERP,in Visual Admin (Services ->key storage , Ticket ). Still the result is same.
How to re-generate the self signed certificate in R3 with CN=ERU ?
or a workaround for this problem.
Regards
Jimmy

HI Jayendra
Recreate the saplogonticketkeypair following the procedure outlined here
http://help.sap.com/saphelp_nw70/helpdata/en/75/c80b424c6cc717e10000000a155106/content.htm
Then you can export the SAPLogonticketkeypair-cert (public key certificate) of the Java AS and import it into the target ABAP system
Important: the following two steps must be done in the ABAP client that will receive the logon tickets i.e the ABAP client that the component/application on the Java AS is configured to connect to e.g the client specified in the portal iview properties or the client specified in a Web Dynpro JCo Destination
(1) Import the public-key certificate of the Java AS into the ABAP systems certificate list using transaction STRUSTSSO2
(2) Add the certificate to access control list
When adding the certificate to the ACL the SID should be set to the SID of the ticket issuing Java AS and the client should be set to the client that the Java AS is writing to the logon tickets i.e the value of login.ticket_client in the Java AS
Remember, in an Add-In installation, where the system IDs are the same, you must change the default client for the J2EE Engine (000) to a client that does not exist on the SAP Web AS ABAP system e.g change login.ticket_client to 999
See: http://help.sap.com/saphelp_nw70/helpdata/en/cb/ac3d41a5a9ef23e10000000a155106/content.htm
The reason for this change is that the system ID and client combination must be unique when tickets are to be accepted by an SAP Web AS ABAP system
By the way it is better to start a new thread with your question rather than bumping a thread that was already set to 'answered'

10.6.8 Java not working. "No compatible version of Java 1.5 is available"

Hey Guys
Firstly I would like to thank you for clicking this question and would ask you please if you have a solution to my problem answer whatever you can. Anyway lets get on with it.
Recently I have been having a problem on my macbook. I am running 10.6.8 as said in title. Previously i was having an inactive plugin error going on and the software update said there were no newer versions available. However when looking for a solution for this by clearing my java cache ect. i somehow ended up with this problem. Whenever I try to run a java based application such as minecraft it says "Cannot launch "Minecraft" No compatible version of Java 1.5+ is avaiable." Also when from this menu i try to open Java Preferences it says "You can't use this version of the application Java Preferences with this version of Mac Os X. You have Mac OS X 10.6.8. The application requires Mac OS X 10.7 or later." I did not download java 1.7 or a different version of Java Preferences outside of the software update. If you have any idea of what's going on please help me out. I am struggling to get on with work and games without java even working.
Thanks for your help
Will

Are you up to date with the updates?
Update for Snow Leopard users:
Apple issued update 12 for Java for OS 10.6:
http://support.apple.com/kb/DL1573
Note: On systems that have not already installed Java for Mac OS X 10.6 update 9 or later, this update will configure web browsers to not automatically run Java applets. Java applets may be re-enabled by clicking the region labeled "Inactive plug-in" on a web page. If no applets have been run for an extended period of time, the Java web plug-in will deactivate.
If, after installing Java for OS X 2013-002 and the latest version of Java 7 from Oracle, you want to disable Java 7 and re-enable the Apple-provided Java SE 6 web plug-in and Web Start functionality, follow these steps:
http://support.apple.com/kb/HT5559?viewlocale=en_US
Further update:
Apple issued this Java related security update No. 13 on February 19:

The standard recommendation is for users to turn off Java except when they have to use it on known and trusted websites (like their bank). Javascript, which is unrelated despite the name, can be left on.

Consuming PI Webservice from Webdynpro Java Not working

Hello SAP,
Environment: CE 7.2.
Resolution expected immediately, Helpful answer is highly appreciated.
Is the namespace should not exceed 60char for PI Webservice, for executing the webservice from Webdynpro Java.
I tried with all the options in executing the PI Service from Webdynpro Java, None of the options worked. I am facing the below error while I was calling the PI Webservice.
I don't see any problem from Webdynpro Java, what ever the procedure I have followed is the standard procedure.
Fortunately when I execute the service from Webservice Navigator, it is working as expected. The same webservice when I consume it from Webdynpro Java it is not working
Options tried so far:
1) Published the Services to Service Registry and there by consuming the PI Service from Service Registry - Not worked
2) Tweaked the URL with few options - Not worked (Tweaking the URL, ex: portType, Binding)
3) Changing the Business Systems in PI and there after calling the service - Not worked
4) Initializing the code, instead of creating Service Controller and calling the PI Service - Not worked.
5) Created a Provider System and tried to call the PI Webservice from Provider System - Not Worked
For all the Options, I am facing the same error which is provided in the screenshot.
Below procedure which I have followed for calling the PI Webservice:
1) Created Adaptive Webservice Model
2) Provided PI Webservice URL (It prompts for PI System UserId and Password)
3) Selected Option - No Service Group Configuration
4) Provided Logical Destination
6) Completed creation of Model
7) Added the model as a UsedModel
8) Right Click on Comp Contr. and selected Apply Template and Created a ServiceController for the model (Entire mapping to comp contr, Initializing the nodes is taken care by Service Contr.)
9) Created an Template Action button and there by calling execute method which is auto rendered from CompContr..
10) Build the project.
11) Activated the code and Run the Application.
12) Getting the below error which is showed in the message.
ERROR MESSAGE:
Exception on execution of web service on destination 'GetPIHRPeopleData' for operation 'SI_CreateHRPeopleData_OS' in interface 'SI_CreatePeopleCompany_OS'

Hi Sankar,
If the webservice is working fine in the Wsnavigator then there is some problem with importing the webservice in webdynpro for Java. Please check the required parameter for creating the Adaptive Webservice Model. After adding in the used model and compoent controller binding, you need to write code for to execute the webservice model.
Please check the code for initialization and execution for the webservice and then test it.

Upgraded to Firefox 4 and now the program I many alarm dealers use with Rapid Response Monitoring no longer works. RR Tech support said it had something to do with a change in Java not working with Firef 4

Rapid Response Monitoring Center developed a program for their dealers to log on to the main frame and look at customer info. The program now has a disclaimer on the log-on page Does not work with FireFox 4. RR tech support said it had to do with Java functions that were not continued in FF4. I can log on but the program will no longer display customer history or anything that seems to have a data base behind the function tab.
See www.rapidweb2000.com or call 1-800-932-3822 and ask for tech support for additional info about what they have found is the problem.

Id this the HP SimplePass Identity manager or Digital Persona fingerprint reader? If it is, the company that make the fingerprint reader have abandoned it. For more details see https://support.mozilla.com/en-US/questions/799388

Java not working in Internet Explorer

I normally use another browser (Google Chrome) but need to use Internet Explorer for a particular online banking service. This service requires a Java applet.
I have the current Java environment (as at 21.3.12), SE 6 Update 31.
Java works in Chrome but does not work in IE8 or IE9.
I have un-installed and re-installed Java several times, tried going back to IE8, turned off ActiveX filtering, confirmed Java scripting is on, checked add-ins are managed correctly and so on and so on, without success. Given Java works it is not a Java
issue but must be an IE issue.
Are there any additional steps or diagnostics I can run to try to identify the problem as I need this to be resolved for the purposes of running my business.
Many thanks!

Hi guys.
I'm having an issue like this and none of the solutions above helped me.
I'm trying to open a specific web page that is not working with Java only on Internet Explorer (7, 8 nor 9). If I try to open in Google Chrome or Firefox it goes fine.
I've tried various versions of Java and all my tries were done both on Windows XP Professional and Windows 7 Professional.
The weird thing is that when I test it through Java webpage or some other page, it goes fine. It is not working only for this specific webpage.
This is the webpage:
http://iweb03ds.magnaclosures.com/stconf.nsf/meeting/mid3FC5EBB1D59C830685257A2900420436
It is a meeting webpage for our company to present their work to our clients and suppliers. I've also followed their own step-by-step advises, but no good either.
Could anyone help me on that?

Java Not Working, And Still No Answers. What Gives?

Okay, decided to start this topic anew, since the only response I got to the other one was a post calling me "rude and impatient" (I guess that's what they're calling "persistence" nowadays..) , instead of...well...ignoring my admittedly pushy and harsh tone and actually being helpful. However, for the sake of it, I do apologize for my attitude in my last topic.
But I digress, let's start off on a new foot, eh? On to the problem that is STILL at hand(in other words, "patience" hasn't gotten me jack, not even a "we don't know yet"):
So last night (10 PM January 20th), the Firefox Plugin Checker said that my Java version was outdated. I also got a pop-up saying that my current version of Java at the time (Java 7 update 10) had vulnerabilities. So to try and fix this, I went to the Java page and downloaded the update (Java 7 update 11).
To check and see if my update was working, I went to Java's check page, as well as another page I use. And here I discovered a problem. I got a notification that an old version of Java had been detected, and another prompt to download the current version (which I had already done). So I erased all versions of Java from my control panel, and tried to check it again. And when I did, I got this: http://oi50.tinypic.com/35b6xx2.jpg and http://oi47.tinypic.com/15fg37p.jpg.
As you can see, both pages tell me that I need to install a missing plugin of some sort. So, thinking this would resolve the issue, I clicked the Install Missing Plugin button. This is what it told me was missing: http://oi45.tinypic.com/302uwbl.jpg. So I clicked next to install it.... and got this: http://oi45.tinypic.com/2cici0x.jpg, which I assume means that the plugin did not install. So I pressed Manual Install... and was lead/linked right back to the Java download page (where it all began, and what doesn't seem to be working in the first place)
I go to check my plugins again (Just to make sure and also for extra information), and it appears to say that my Java version is current (is that what "Java Deployment Toolkit 7.0.110.21" is? I don't know, I am not good at technology at all. Either way, here is what it looks like: http://oi48.tinypic.com/4kxzz4.jpg). So...if it is current, why is it not working (i.e. I am unable to play games, DO MY COLLEGE CLASSWORK, or play Java-based games)?
If it helps anything, here is what my control panel looks like in regards to Java right now: http://oi45.tinypic.com/2qlxu9t.jpg Am I missing anything that would make Java work?
And before anyone says that Java is not essential: It may be that way to you, but I need Java to do classwork for college. Veterinary college.
So, in short, what is going on with Java, and how can I fix it?
EDITEDITEDIT: I Have found that I can do my classwork without Java. HOWEVER, this DOES NOT mean that the problem is solved or over with. I STILL WANT TO KNOW HOW TO FIX THIS PROBLEM AND GET JAVA TO WORK. Even if I never actually need it, I would still like to have a (working!!!) Java version because of two reasons: 1) I would rather have such a program and not need it, than need such a program and not have it, and 2) aesthetics. Sorry to say, but I am very particular about how things look when it comes to my belongings, and the fact that Java is messing up is making me actually stressed. In short, I still want the above issue solved, even if it's just purely for the sake of Peace Of Mind.
Another note: I would (please!) appreciate a timely response on this matter. Even if the response is a "We don't know what the issue is and/or we are working to solve this issue.", that would satisfy me for the time being. I would just like a semi-timely response that would let me know that FF/contributors here have read the above and actually give a semblance of a care about their userbase.
Thank You.

The first prompt you see in Firefox to activate Java is because Java is currently on the Mozilla blocklist ( the "Hot Topic" article [[How to use Java if it's been blocked]] explains the reason for block and how to activate Java, including how to bypass the plugin activation prompt for trusted sites).
cor-el is right about why you are seeing a second [http://oi48.tinypic.com/de8f8y.jpg Java "Security Warning"] when trying to view Java applets, that you have to click to run. This is a ''' Java''' security feature and not anything Firefox does.
Try the same Java sites in Internet Explorer .... don't you also see the Java "Security Warning?" If you want to lower your Java security back to "Medium" in the Java Control Panel, see http://docs.oracle.com/javase/7/docs/technotes/guides/jweb/jcp.html#security for details. That's up to you but I would leave it on "High " since Java 7 is still basically insecure, according to the reports I've seen and [https://blog.mozilla.org/security/2013/01/11/protecting-users-against-java-vulnerability/ this "Protecting Users Against Java Vulnerability]" Mozilla blog post.
If the second Java prompt is your only remaining issue then your problem is really solved, since it is a new Java security feature and not anything in Firefox.
Some background:<br>
At the time I was helping you in the [https://support.mozilla.org/en-US/questions/944267 older thread you started] (now locked because you started this one) the solution to uninstall JavaFX wasn't known. On Dec 13th I wrote, ''There may be problems with Java 7 Update 10 since a number of Windows users have reported that Firefox is not detecting the plugin'' and I linked to a couple of related threads, including [http://forums.mozillazine.org/viewtopic.php?f=38&t=2628935 this MozillaZine thread], in which uninstalling JavaFX as a solution was posted 22 Dec 2012. On 25 Dec 2012 in the same MozillaZine thread, I posted a link to [https://bugzilla.mozilla.org/show_bug.cgi?id=820759#c12 this Dec 24th bugzilla comment] by an Oracle employee, who posted that uninstalling JavaFX was a solution for '''Oracle's''' Java 7 detection bug. Oracle has been working on the bug (to be fixed in an upcoming Java 7 release) and they created [https://www.java.com/en/download/help/firefox_java.xml this java.com help page], which is now included in the related MozillaZine and Mozilla Support articles on Java that I posted above.

Java option icon not displaying AND Java not working, even after deleting and re-installing Java

Hi, I have uninstalled and re-installed Java. When I look at Add-ons, it shows Java Platform SE7 U17 10.17.2.2 and Java deployment Toolkit 7.0.17… 10.17.2.2 enabled. But it is not working – and I do not see the Firefox plugin to allow occasional use of Java.
One useful thread which discusses several difficulties in detail is
https://support.mozilla.org/en-US/questions/944956?esab=a&as=aaq
I tried to follow scrumpyjoe’s advice in this thread:
“This fixed it for me (32 bit windows) after installing Version 7 Update 10, but not seeing the plugin:
1) start regedit
2) navigate to HKEY_LOCAL_MACHINE\SOFTWARE\MozillaPlugins
3) right click, add New Key, name: @java.com/JavaPlugin,version=10.xx.xx
4) click on it, then right click and add new string value, name: path
5) right click, Modify, change value data to: C:\Program Files\Java\jre7\bin\plugin2\npjp2.dll [check if this is the right dll for your setup]
6) exit regedit
7) start FF”
- but (unless I have made a mistake) it has not resolved my problem.
What can I try next, please ?

UPDATE 2apr13
I have now unistalled and re-installed Firefox 20.0. restored preferences etc. using MozBackup, and Java Platform and Java Toolkit10.17.2.2. both show as working Add-ons - BUT STILL NO JAVA AND STILL NO RED ICON IN TOOLBAR. What is going on, please ?

I don't understand any of these replies. How do I get Java to run for Pogo.com? I had no problems a week ago. I do not have the red icon. I am not a programer so keep it simple. I am a 59 year old speech therapist.

Why does for-each not work with Enumeration?

I'm sure there's some reason for this but I don't know what it would be.
I am calling an existing method [http://java.sun.com/javase/6/docs/api/java/util/zip/ZipFile.html#entries()] And it returns Enumeration<? extends ZipEntry>
What I would like to do is
Enumeration<? extends ZipEntry> entries = myzipfile.entries();
for(ZipEntry ze : entries)but this won't compile because Enumeration is not an Iterator. Which kinda sucks.
Obviously (I think) Enumeration can't be retrofit to be an Iterator without problems and the APIs that return Enumeration can't change without problems so it seems the only way that for-each would work with an Enumeration is if for-each was allowed to work with Iterator and Enumeration.
So my question is, why isn't it? (To be clear I know how to enumerate an Enumeration, I'd just like to know if anybody has a clue why for-each was not designed to support Enumeration)

Still it does'nt fully answer the why question. Why does the Collections class not implement a static iterable(Enumeration) method that does not impose the overhead of an addiditional ArrayList, as in the following class:
import java.util.Collections;
import java.util.Enumeration;
import java.util.Iterator;
import java.util.zip.ZipEntry;
import java.util.zip.ZipFile;
public class EnumerationToIterable {
    public static <T> Iterable<T> iterable(final Enumeration<T> enumeration) {
     return new Iterable<T>() {
         @Override
         public Iterator<T> iterator() {
          return new Iterator<T>() {
              @Override
              public boolean hasNext() {
               return enumeration.hasMoreElements();
              @Override
              public T next() {
               return enumeration.nextElement();
              @Override
              public void remove() {
               throw new UnsupportedOperationException();
    public void iterateOne(ZipFile myzipfile) {
     Enumeration<? extends ZipEntry> entries = myzipfile.entries();
     for (ZipEntry ze : Collections.list(entries)) {
         // process ze
    public void iterateTwo(ZipFile myzipfile) {
     Enumeration<? extends ZipEntry> entries = myzipfile.entries();
     for (ZipEntry ze : iterable(entries)) {
         // process ze
}Could it be more simple?
(Thanks for the Dukes)
