I have a .net application which needs to expose a service consumed by a java client. The service can't be public. There should be some authentication mechanism for the client. What is the best way to do this? I'm new to web services and am confused by all the soap, wsdl etc. and have also heard a lot that it'll be a pain to get the two to communicate. Your thoughts?
More of a wiki list/collection, I'm looking for a list of good Java desktop apps. I've added a couple below to get started. Please list the framework/widget toolkit being used if it's know as well.
I need to invoke .jar file in separate JVM from another java application, and it very CPU-consuming, so it should run with background priority in order not to affect the rest of the system. Is there any cross-platform method to do this?
Given the following code:
public class Test {
public void method(Object o){
System.out.println("object");
}
public void method(String s) {
System.out.println("String");
}
public void method() {
System.out.println("blank");
}
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
Test test=new Test();
test.method(null);
}
}
Java prints "String". Why is this the case?
Hi,
I have a lot of experience in C and Python, but I'd like to pick up some Java. I was curious if there was a "quick and dirty" guide tailored for people with previous CS background. I'd prefer free online resources but appreciate any suggestion.
Thanks,
Brian
I've looked around for a good example of this, but I haven't run into one yet. I want to pass a custom string array from java to oracle and back, using the IBATIS framework. Does anyone have a good link to an example? I'm calling stored procs from IBATIS.
Thanks
What JAVA library should I be using to Hash passwords for storage in a database?
I was hoping to just take the plain text password, add a random salt, then store the salt and the hashed password in the database.
Then when a user wanted to log in, I could just take their submitted password, add the random salt from their account information, hash it and see if it equates to the stored hash password with their account information.

Consider following SWT code example:

How can I separate the inline defined class?
Thread thread = new Thread() {
public void run() {
...
}
};
I want to define a separate class which updates the table just like it does here. How do I pass the list back to the table? Example code?
This question showed up on my mid-term exams and I've been searching for correct answer for some time. I know that Java interfaces can't be directly instantiated so they don't need constructors and that they can have only public static final attributes so they don't need constructors to set them up but that's not the expected answer.
Hi all! I'm making an android program that retrieves content of a webpage using HttpURLConnection. I'm new to both Java and Android.
Problem is: Reader reads whole page source, but in the last while iteration it doesn't append to stringBuffer that last part.
Using debbuger I have determined that, in the last loop iteration, string buff is created, but stringBuffer just doesnt append it.
I need to parse retrieved content. Is there any better way to handle the content for parsing than using strings. I've read on numerous other sites that string size in Java is limited only by available heap size. I've tried with StringBuilder too.
Anyone know what could be the problem. Btw feel free to suggest any improvements to the code.
Thanks!
URL u;
try {
u = new URL("http://feeds.timesonline.co.uk/c/32313/f/440134/index.rss");
HttpURLConnection c = (HttpURLConnection) u.openConnection();
c.setRequestProperty("User-agent","Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; InfoPath.1; .NET CLR 2.0.50727)");
c.setRequestMethod("GET");
c.setDoOutput(true);
c.setReadTimeout(3000);
c.connect();
StringBuffer stringBuffer = new StringBuffer("");
InputStream in = c.getInputStream();
InputStreamReader inp = new InputStreamReader(in);
BufferedReader reader = new BufferedReader(inp);
char[] buffer = new char[3072];
int len1 = 0;
while ( (len1 = reader.read(buffer)) != -1 )
{
String buff = new String(buffer,0,len1);
stringBuffer.append(buff);
}
String stranica = new String(stringBuffer);
c.disconnect();
reader.close();

I would like to open a webpage and run a javascript function from within a java app.

I'm in the process of weeding out all hardcoded values in a java library and was wondering what framework would be the best (in terms of zero- or close-to-zero configuration) to handle run-time configuration? I would prefer xml-based config-files, but it's not essential.
Please do only reply if you have practical experience with a framework. I'm not looking for examples, but experience... Thanks for taking the time.
Hi,
I would like to know if its possible to deploy java class files without restarting JBoss server. I am using jboss v4.2.2.
Also, when I try to deploy jsp files, it works fine and server picks up the changes almost instantly.
Thanks a lot in advance :)
