IcedTea-Web not launching JNLP files with icon SIZE="AAxBB" in the file

[atfield90]

Hi everyone,

i noticed that IcedTea-Web is unable to launch jnlp files that contains the function size to scale icon size, here's and example:
<icon href="http://downloadcomunica.infocamere.it/comunica_webinstaller/comunica/RBcomunica48.gif" size="48x48"/>

The above one is just an example.
I know that modifying size="48x48" into width="48" height="48" fixes the problem, but since some developer still uses the size function, is it possible to implement something in IcedTea-Web that makes it compatible with size function?

Here's the error when you try to launch a jnlp with size function in it:

net.sourceforge.jnlp.LaunchException: Fatal: Read Error: Could not read or parse the JNLP file. You can try to download this file manually and send it as bug report to IcedTea-Web team.

Thanks in advance for your help,

https://docs.oracle.com/javase/8/docs/technotes/guides/javaws/developersguide/syntax.html does not specify "size" as an attribute for icon or applet.

ITW has code to read size attribute for the icon tag but parses it as integer instead of as String and then extracting w and h from it.

We will try to fix it in a future release but it is low priority.

However, you could fix it in the Parser.getIcon() method and raise a PR.

Hi @janakmulani, i've raised a PR to fix the problem, number #869.

I'm trying to compile this fork that i made in order to test it in windows, but when I try to compile it I always get this error message:
"+ which cargo

Is Someone able to help me for this error?or otherwise, can someone compile an msi of the fork that I mad in order for me to test it in Windows?

Thanks.

Hi, I am not familiar with building ITW and its installer. However I took your fix and created a branch icon_size_attr and tested it on windows by building OpenWebStart. It works. I have created a PR to be merged after review.

[atfield90]

Hi @janakmulani, would you be able by any chance to share the OpenWebStart version that you builded? Thanks.

[janakmulani]

Sure. Can you please send an email to [email protected]?

Issue has been solved with the merged PR, #869. We can close this one.
