Could not read or parse the JNLP file

bjorndarri commented 4 years ago

I'm running an application in Windows by clicking a link to a jnlp file ('ata_dev.jnlp'), first time around everything works as expected, the file is downloaded (by Chrome) and the application runs, but the second time the jnlp file is downloaded again and gets a new name 'ata_dev (1).jnlp', since the file already exists in the downloads folder. OpenWebStart then fails to run with the new jnlp file.

Here's the error message, the relevant line in bold, looks like the problem lies in URL-encoding:

net.sourceforge.jnlp.LaunchException: Fatal: Read Error: Could not read or parse the JNLP file.

Forgot to add that this problem was introduced in version 0.5.

Just to clarify:

When you download ata_dev.jnlp you can simply start it and everything is working fine.
When you download the file a second time it will automatically renamed (by the operation system) to ata_dev (1).jnlp
When you want to start ata_dev (1).jnlp OpenWebStart will end with an error
In OpenWebStart 0.4. starting ata_dev (1).jnlp worked correctly.

Is this correct?

could be a problem with the white space in ata_dev (1).jnlp
