A Java Preferences for larger amounts of data

After two days of hacking around with the Java Preferences,

I have come to the conclusion that Preferences were

never meant to store large amounts of data.

It seems to me that this is an important sub-problem.

One of the people who has addressed the problem is

David Croft. His code, which uses properties, is still unable to

serialize large amounts of data, for reasons I cannot fathom.

[url removed, login to view]

shows his file example.

The simplest example I can use to break his code appears below.

We are interested in a java program that enables

the storing of larger amounts of data in file preferences (perhaps [url removed, login to view] or so).

Thanks!

public static void main(String[] args) throws BackingStoreException {

Preferences p = getPreferences([url removed, login to view]);

for (String s : [url removed, login to view]()) {

[url removed, login to view]("p[" + s + "]=" + [url removed, login to view](s, null));

}

StringBuffer sb = new StringBuffer();

for (int i=0; i < 1<<11; i++){

[url removed, login to view](" "+i);

}

[url removed, login to view]("hi", true);

[url removed, login to view]("Number", [url removed, login to view]([url removed, login to view]()));

[url removed, login to view]("large string",[url removed, login to view]());

}

public static Preferences getPreferences(Object c) {

[url removed, login to view]("[url removed, login to view]", [url removed, login to view]());

File preferenceDir = [url removed, login to view]();

[url removed, login to view]("preferenceDir:"+preferenceDir);

File preferenceFile = new File(preferenceDir,"[url removed, login to view]");

[url removed, login to view](SYSTEM_PROPERTY_FILE, [url removed, login to view]());

[url removed, login to view]("storing preferences in:"+preferenceFile);

return [url removed, login to view]([url removed, login to view]());

}
