want the

Since libxml2 is a .dylib (not a nice friendly .framework) we still
have one more thing to do. Go to the Project build setting...
System.BadImageFormatException: Could not load file or assembly (from installutil.exe)
...on for this exception these days is attempting to load a 32 bit-specific (/platform:x86) DLL into a process that is 64 bit or vice versa (viz. load a 64 bit-specific (/platform:x64) DLL into a process that is 32 bit). If your platform is non-specific (/platform:AnyCpu), this won't arise (assuming no...
Setting the default Java character encoding
...
I think a better approach than setting the platform's default character set, especially as you seem to have restrictions on affecting the application deployment, let alone the platform, is to call the much safer String.getBytes("charsetName"). That way your applicatio...

Why can't a text column have a default value in MySQL?
... 4:36pm:
On MS Windows the "no DEFAULT" rule is an error, while on other platforms it is often a warning. While not a bug, it's possible to get trapped by this if you write code on a lenient platform, and later run it on a strict platform:
Personally, I do view this as a bug. Searching for "BLO...

Java ByteBuffer to String
...nswer.
Your approach would be reasonable if you knew the bytes are in the platform's default charset. In your example, this is true because k.getBytes() returns the bytes in the platform's default charset.
More frequently, you'll want to specify the encoding. However, there's a simpler way to do t...
