Re: [Joelib-devel] Is joelib.jar compatible with applet?

[joerg.wegner <joe...@we...>]

Dear Takayuki,

first the Webstart application is deprecated and uses a pretty old =
JOELib
version, but this is just a site note.

Second, all descriptors/features and file formats are defined in the
joelib.properties file. Therefore, this an extremely important property
definitions file.
I still do not know from the messages provided what is going wrong. Can =
you
enable the debug mode in log4j.properties for
wsi.ra.tool.BasicResourceLoader
wsi.ra.tool.BasicPropertyHolder

Those are the relevant classes for getting and loading the properties.
Usually those classes should be able to get the data from String, URL, =
and
File resources.

I had also already some problems with those classes, especially when =
working
in combination with other projects and dependencies. Anyway, this is a
powerful outsourcing of parameters and avoids hard coded (hidden) =
features,
so it is worthwhile solving this.

Please check those classes and hack them if necessary. I assume that =
some of
the security settings might not be correct, so you should maybe also =
check
Java-Applet security issues, but this is a general JavaApplet problem =
and
you should check Google and SUN pages for that.

Please let me know, if this message was helpful and what the status of =
your
problem is.

Joerg
