Problems which are solved by upgrading XXE
and/or the Java™ runtime are not listed here. Therefore, the first
thing to do if you have problems is to upgrade XXE to latest
version and to upgrade Java to latest supported version (no beta

- When XXE is started in a directory which has an
UNC filename (example: \\home\jsmith), opening
documents is very slow or fails with strange error messages such as
"Cannot open file XXX:
Workaround: when XXE is
started in a directory which has an UNC filename, loading
the XML catalog XXE_install_dir/addon/config/catalog.xml
silently fails. Therefore, the workaround is to start XXE
in a directory which has not an UNC filename, for example:
In order to do this:
- Right-click on the XMLmind XML Editor “icon”
that you use to start XXE. For example, right-click on
the XMLmind XML Editor menu item found in the Start
menu > All Programs > XMLmind XML Editor
- This will display a popup menu. Then select the
Properties menu item.
- This will display a dialog box. Then select the Shortcut
Tab and change the Start in field to, for example,
- After that, always start XXE using this modified
- XXE is much too small on a Linux computer having a very
high resolution (HiDPI) screen.
Workaround: on Linux
computers, HiDPI is often not automatically detected. You'll
have to use the "Display scaling" controls found in the
General section of the Preferences dialog box.
- Known problems related to the clipboard:
- XXE randomly hangs for a couple of minutes. This
seems to happen only on Linux with a
JavaTM runtime 1.6+. This often happens
when OpenOffice/LibreOffice is also
Workaround: using an external application, update
the contents of the system clipboard by copying to it (i.e.
by using Ctrl-C) a small piece of text.
- Copying text or images from XXE to OpenOffice/LibreOffice works fine but
the opposite operation often hangs XXE (or at best
makes it very, very, slow).
Workaround: the workaround to
unblock XXE is to copy a piece of text to the clipboard
using any application other than OpenOffice/LibreOffice.
- Copying images from XXE to the Gimp works fine but the opposite
operation will not work.
- When using window managers other than the KDE or Gnome standard
window managers, the XXE main window is displayed at a
wrong place with a wrong size.
Workaround: Java™ seems to
be tested only against the Gnome and KDE standard window managers.
Therefore, you unfortunately need to use another window
- Many Web browsers will simply download the
file without attempting to open it in the associated javaws
program (Java™ Web Start launcher).
asked if you want to really want open
javaws, please answer yes.
Confirm that you
want to always open ".jnlp" files:
Note that once the
xxe.jnlp file has been downloaded and saved somewhere by
the Web browser, the Web browser is no longer needed to start
XXE. Simply double-click

- By default, XXE uses macOS native file chooser to let
the user select a file. When deployed using Java Web Start, for an
unknown reason, this macOS native file chooser becomes

"Use the native file chooser in preference to the multi-platform file
chooser" in the Preferences dialog box.
