WEASIS: Cannot read properties file: /weasis/conf/config.properties?

[Stephen Walters]

Any help would be much appreciated, this error started after the JAVA updates.   It was working prior to the r40 java update.

I'm not sure what the source of the issue is.   I've included the exception and a sample of the JNLP that is used to launch the program. 

Thank you for you help in advance!

You must replace "${weasis.base.url}" by "http://www.dvminsight.com".

I would recommend to use weasis-pacs-connector (build JNLP + xml manifest) or JNLP-Builder (only build JNLP but let give in properties the URL of the manifest or the URL of images).

[Stephen Walters]

Perfect!  That's exactly what was wrong!   I was assuming that the $ would be replaced with the base URL string.
