In Java, is there a way to force a JVM instance to run on a single CPU/Core.
Additionally is there a way for given thread to figure out what CPU it is running on?
I'm working my way through the NotePad tutorial, and that's all fine - I'm not a Java programmer but it's close enough to C# (or vice versa) to make it easy to pick up. I'm surprised that there aren't any RAD tools for Android apart from Mobiforms. Is there anyone out there with experience of Mobiforms ?
Has anyone seen a recent (and fairly balanced) study into the relative costs for software development using differing languages ? I would particular like to see the relative costs of Java Vs. C# Vs. Delphi.
I have imported a GWT project from GIT , but when i run maven Install
it says
.m2\repository\commons-logging\commons-logging\1.1\commons-logging-1.1.jar; cannot read zip file entry
and if i simply run my application , i get this
\git\my-Search-Engine\qsse\war}: java.lang.NoClassDefFoundError: com/google/inject/servlet/GuiceServletContextListener
I tried to find out the way , one solution i found was to move the guice-servlet-3.0 from build path to \qsse\war\webinf\lib
but if i do that i start gettin the exception
ava.lang.NoClassDefFoundError: com/google/inject/Injector
any idea how can i resolve this
Suppose I'm running several servers serving basic requests on my local network (say a home network, where all machines generally have an IP in the form K.K.K.x, where x is variable). Is there an easy way to discover all such servers? I would need to find each IP on the network running a particular java server application.
Quick question:
While debugging Java code, Strings show up only till a certain length, after which Eclipse shows "..."
Is there any way to inspect the entire string? (This eases the pain of adding logging statements for debugging everywhere)
Hi,
ok it is 'easy' to make jna wrapper solution for mapping exported functions within dll using jna:
long f1(int x), just int
long f2(char* y), just char[]
but how to deal with long f3(char** z) ?
I need f3's result(long) as well as z value on java side.
Please don't say cpp code should be rewritten to avoid this:-)

I don't know why it begin with 01h
It is possible to use Java class files which includes annotations that are not present at runtime?
Example: I want to write a class with the JPA @Embeddable annotation, which would be present at compile time (maven scope: "provided"). But the annoatation definition could be absent at runtime, if the class is used outside a JPA application.

Hi, I am a C++ / Java programmer and the main paradigm I happen to use in everyday programming is OOP. In some thread I read a comment that Type classes are more intuitive in nature than OOP. Can someone explain the concept of type classes in simple words so that an OOP guy like me can understand it?

This link is very good for C#, what about java. I serach but i did not find good solution.
I want a simple client that takes a few parameters (Method, URL, Parameters), makes an HTTP request, and shows me the results that were returned.
A browser obviously can easily send GET and POST requests, but I have no good ideas on DELETE and UPDATE.
Did I miss something in browser 101, or is there a common freeware tool to do this? I've seen other threads that give me Java APIs for a simple client, but that's not what I'm looking for.

I want to create a simple clock using Java. The code is so simple that I will give an example:
for(int i=0;i<=60;i++)
jLabel11.setText( Integer.toString(i) );
The problem is while I'm running my program the result didn't show each update in sequence.
It show only the 60 digit immediately, without showing the change from 1 to 2 to 3 ...
How can i fix this problem?

In particular I am wondering what should I do with the jar files of external library that I use (should it be included into my .jar file?).
Moreover, should I generate some manifest files?

I want to view events over specific time range for a specific calendar, but am having trouble using the API, It is a generic API, and it reminds me of using the DOM. The problem is that it seems difficult to work with because much of the information is in generic base classes.
How do I get the events for a calendar using Groovy or Java?
Does anybody have an example of passing credentials using curl?
