I need a nautilus-style file picker in java, where the files are shown "gallery-style" with a customisable thumbnail for each file. Is it possible to make the standard open file dialog do this? If not, does anyone know of an open-sourced widget that I can use?
I'm trying to install the Java Enterprise Edition 6 on my workstation. I downloaded the installer from the Sun website. Whenever I get to the option in the installer "JDK Selection" I'm told to manually select a JDK. I gave it my path (C:\IBM\rad7\jdk\), and was told it is invalid. What do I need to do to successfully install JEE6?
Should a future release of Java deprecate the use of raw types to force the migration to generics? I could also see having raw types not allowed by default but allowing them via a compile flag for legacy code.
I have written a java application which is a RMI server. I need to start rmiregistry to run this application and i also want my apllication to start automatically when the system starts.
I have converted my application into a windows servise. When i try to start my service it shows this error
Error 1067: The process terminated unexpectedly
Is it because my program throws an exception when my application is started before the rmiregistry is started.
In Java I'm trying to test for a null value, from a ResultSet, where the column is being cast to a primitive int type.
int iVal;
ResultSet rs = magicallyAppearingStmt.executeQuery(query);
if (rs.next()) {
if (rs.getObject("ID_PARENT") != null && !rs.wasNull()) {
iVal = rs.getInt("ID_PARENT");
}
}
From the code fragment above, is there a better way to do this, and I assume that the second wasNull() test is redundant?
Educate us, and Thanks
In python I can construct a HTML string without worrying about escaping special characters like < or " by simply enclosing the string in triple quotes like:
html_string = """
<html>
<body>
<p>My text with "quotes" and whatnot!<p>
</body>
</html>
"""
Is there a similar way to do this in Java?
I have started making some small Java games that run in a browser and have found a couple of game portals where I can host then (GameJolt.com, JavaGameTomb.com and Games4j.com). Most of the other portals I find either only allow Flash or offer the games for download.
Apart from those above, what other portals exist that allow hosting applets?
Today I was browsing through some question on this site and I found mention of enum being used in singleton pattern and that there are some thread safety benefits to such solution.
I never used enums and I have been programing in java for more than couple a years now. And apparently they changed a lot and now they even do full blown support of OOP within them selfs.
Now why and what for should I used enum in day to day programing?
Im using Java to create a maze of specified "rows" and "columns" over each other to look like a grid.

In Java if an input argument to a method is invalid, we can throw an IllegalArgumentException (which is of type RuntimeException). In C++, there is no notion of checked and unchecked exceptions. Is there a similar exception in standard C++ which can be used to indicate a runtime exception? Or is there a common style not in the standard but everyone follows in practice for a situation like this?
Or, should I just create my own custom exception and throw it?

ipString is a String representation of an IP address with spaces instead of dots.
String[] ipArray = ipString.split(" ");
String ip = "";
for (String part : ipArray){
if (part != null){
ip += part
}
}
ip = ip.trim();
int ipInt = Integer.parseInt(ip); // Exception is thrown here.
Exception in thread "main" java.lang.NumberFormatException: For input string: "6622015176".
Could someone explain why this exception is being thrown?
Is there a third party library to detect the use of a Java 1.5 library when compiling with a 1.5 compiler with -source 1.4 and -target 1.4? I could use a 1.4 rt.jar in the bootclasspath however I hope there is a better way. To be used, for example, to fail the compile/build if a newer library is used.

Per the title, do you find the default Java logging framework sufficient for your needs?
Do you use alternative logging services such as log4j or others? If so, why?
I'd like to hear any advice you have regarding logging requirements in different types of projects, and when integrating frameworks is actually necessary and/or useful.
