[Configuration] autoSave causing FileNotFoundException
I believe I've found a bug. When trying to use autoSave,
jakarta-commons-configuration gives me the following error:
-----
java.io.FileNotFoundException: file:/tmp/test.xml (No such file or
directory)
at java.io.FileOutputStream.open(Native Method)
at java.io.FileOutputStream.<init>(FileOutputStream.java:179)
at java.io.FileOutputStream.<init>(FileOutputStream.java:131)
at

org.apache.commons.configuration.AbstractFileConfiguration.save(AbstractFileConfiguration.java:216)

at
org.apache.commons.configuration.XMLConfiguration.setProperty(XMLConfiguration.java:371)
at test.Main.main(Main.java:22)
-----
For some reason, it converted my File into a URL but then tries to
access it as a File path again when trying to persist my settings.
Here is a simple test application to reproduce the problem:
-----
package test;
import java.io.File;
import java.io.FileWriter;
import java.io.PrintWriter;
import org.apache.commons.configuration.XMLConfiguration;
/**
* Illustrates a bug in jakarta-commons-configuration
*
* @author Mark Roth
*/
public class Main {
public static void main(String[] args)
throws Exception
{
File configFile = new File("/tmp/test.xml");
createSampleTestXml(configFile);
XMLConfiguration config = new XMLConfiguration(configFile);
config.setAutoSave(true);
config.setProperty("a", "b");
}
private static void createSampleTestXml(File f)
throws Exception
{
PrintWriter out = new PrintWriter(new FileWriter(f));
out.println("<root>");
out.println(" test");
out.println("</root>");
out.close();
}
}
-----
Is this a known error? Any known workarounds?
Thanks,
