java.lang.Exception: Unable to derive image dimensions #92

Closed SimSonic closed 3 years ago

SimSonic commented 7 years ago

Hello.

I've tried to run ScadaBR and Scada-LTS (latest "release" from here) under Tomcat 9 (and 8 too) but everytime I receive this messages in tomcat9-stdout.2016-xx-xx.log:

2016-12-21 15:31:33 Commons Daemon procrun stdout initialized

for every folder name in ScadaBR\graphics\.

OS: Windows 7 x64. Java: Oracle 8u111. Tomcat: 8 and 9.

Thanks.

I saw this same error previously, it is related to running on Tomcat 8.

If you run on Tomcat 7 you do not see this error (I don’t think that ScadaLTS has been ported to Tomcat 8, and I know that ScadaBR only runs on Tomcat 7).

Hello, this issue has been fixed in the following commit: https://github.com/SCADA-LTS/Scada-LTS/commit/ba32e610a99253c32342b69e6d4818ca40af3b83

This bug has been fixed in followed commit c6efb02f88fbaef9d3e5b4d839a67a8a246f1d0f on a related branch. Now Images for Scada-LTS works both in Tomcat7 and Tomcat8 and that log error do not exists any more.

It is a problem with line 99 in ViewGraphicLoader.java where String imagePath = file.getPath().substring(path.length()); path.length() has differ between this two version of Tomcat.
