Wanting to use the messages in ICU4J, I was lead to believe one needed to run the command:
genrb root.txt
This produces root.res.
However using the following snippet results in the error message below:
UResourceBundle urb = UResourceBundle.getBundleInstance("Your package path","root");
>Data file yourPackagePath/root.res is corrupt - ICU data file error: Header authentication failed, please check if you have a valid ICU data file
then after some googling came across one entry in the mailing list that suggested I check the endian-ness.
Chris, Are you running generating the res file on a windows machine? If yes you should run it through icuswap utility and make the res file big endian before you can load it in ICU4J. Have a look at icu/source/tools/genrb/gendtjar.pl for more information. Best Regards, Ram Viswanadha Chris Hsu wrote: > Hi; > > I am new to ICU4J.

It’s probably important to note that the icuswap utility looks to be discontinued.
Anyways to fix this issue you need to do icupkg -tb root.res if using ICU4J when root.res was generated on windows.
