Dear All,
Kindly be informed that I am facing an issue where every time i connect to a secured HTTPS server I get the following error "Quote: Exception in thread "main" javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No subject alternative names present
"
I don't know how to solve this issue and I googled it and no luck. Also please be noted that I am a beginner in Java.
Thanks in advance

My aim is to access a jsp page from an android application.
When I searched the net i got the information that its possible with WebView.loadUrl() method.
But when I tried it in my application I got the error that Webpage not available. But the jsp application is running and i'm getting the page, but through android, it's error.

Well you need to investigate why your program cannot get that page.

Full stop.
Ok, I'll just toddle back over to the C# forum. :diminishing tuneless whistle:

Dear sir , could you be more specific about what you are trying to convey , I didnt understand , actually i wanted help on the easiest yet secure language to program LAN

There is no way for a general language to be secure.
That is because how applications are implemented as well as the business domain and even where they run impact their security.

Tell your friend he is wrong. The last project I worked on used Java to communicate between clients (Windows, Linux, UNIX) and server, transferring messages, objects etc. It worked fine.

Which often means that the assertion is nonsense, regardless of what the assertion is.
At best, what someone might have originally told him was that Java doesn't have access to raw sockets. Which means, for example, that you can't write a tool like wireshark in Java (java only excluding JNI.)
Now at worst it might have been a convoluted way of saying that you can't use Java to write an IP stack. But then you can't use Java for many driver tasks and you wouldn't want to anyways. And there are other odd ways of expressing that as well such as suggesting that you wouldn't use Java to create a high speed router.
However if you want to use it to create something much more normal like a web server then there is no problem.

When i discussed this with my friends one of them told me about that ""DISADVANTAGE"" of JAVA , you seem to have experience in it , could you please help with your advice regarding the time it might require us to complete the chat messenger . we are 2 in number and we have learnt and started JAVA implementation just a month ago
Sorry, but I can help with specific questions but I cannot provide training and/or consultancy services. You should get familiar with the Java Tutorials[^] which contain some excellent training materials. Also try some Google research and you will find lots of useful information.

thanks a lot , i got some good examples for socket programming working on them now 
|
|
|

I did some network programming (socket stuff) in many languages including java (also in C/C++, pascal, python). I think networking in java is quite OK. Since it has a crossplatform api you have access to limited functionality of the native socket api of your host platform but that isn't a problem in most of the cases especially if you are developing simple UDP/TCP applications. Whether to use java or not: it depends on your goals.

the error message is as follows:
Failed to load the application on to the emulator device.
|
|

Wait for the emulator to setup completely and then test your app. Also, I would leave your AVD open so you don't have to wait so long every time you run your application.
When it shows the red writing, don't close anything - leave it there and then press the run button again.

Please check if your app has any errors.I had encountered this error a lot when i started App development there might be some error in your layout file or string file or sometimes you might have given same IDs to different components and if all this doesnt work check yuor android manifest file. If all these doesnt help you in error removal then create a new project try copying the code part by part . This surely will help you

Hi,
I have recently read a book by David Brackeen called 'Developing Games in Java'. I understand the code in the book and am currently modifying the game engine however; I have come across a problem whilst trying to create the player inventory.
I am using code in beanshell scripts to update objects in the game and looking through different scripts by David Brackeen I came across this code, ’player.getInventory().setRedKey(true);’. I understand it means ‘if the player object’s inventory does not have the red key after a red key collision, add the key to the inventory’.
My question is how would I write this code into my netbeans IDE (so it is recognised in the script) as nesting the ‘setRedKey(Boolean)’ brings up errors when I put it in the ‘getInventory()’ helper method of my GameObject class.

We have no idea what this method, or even its containing class, is supposed to do, so it is impossible to make any suggestions. Also, if you get errors then provide the exact text of the messages and the lines of code that cause them.

Thank you Richard. I had numerous errors but the main being a reflection error stating that .setRedKey(true) could not be found in my .bsh script (however it was there).
I think i have fixed the problem by removing 'player.getInventory()' and just using the method 'redKey.setCollected(true)', this puts the redKey object into an arrayList which i can then use as the players inventory to be shown on the screen when the player presses the 'i' key.
Kurt.

There are frequent news stories about security holes in Java. Do these apply mostly to browser plug-ins, or are there similar numbers of security issues in other components, such as JVMs, JavaFaces & Oracle ADF, Spring and other frameworks? In particular, I am concerned with security in Java code and components running on a web server.
If you think 'goto' is evil, try writing an Assembly program without JMP.
