Hi, I am evaluating trial version of excelsior to convert an existing tomcat 8 - application war file. the war file is maven build via the jet maven plugin. The following additional details: Windows server 2012 Tomcat8 Java8 codes When the exe was generated, it could not run due to not able to find tool.jar. But there is no tool.jar for java8 but there is a tools.jar. I am not sure why it is looking for tool.jar. However, if I used the JetControlPanel directly to load the war file, I was able to run it. Strangely, when i use JetControlPanel to build it, the exe i cannot run as its looking for tool.jar again. Please advise how i can get the built exe to work. Does it need to reside under some directory?
