Open Source Jar file and Failed to load Main-Class manifest

Question

I downloaded an Open Source tool from www.openempi.org used to find duplicate patients. It is referred to as an EMPI tool (Enterprise Master Patient Index). I am a .Net programmer and not a Java programmer, but I have worked with other Java products where I receive a Jar file and run it like a Windows executable.

The zip file contained several Jar files but when I double-click on them I get Failed to load Main-Class manifest from.... After I Googled this term and reading a few posts about it, including several on this site, this seems to indicate that I should have done something different when creating the Jar file, but I didn't create the Jar file. Will I need to use Eclipse or some other tool to get past this, or is there something I'm doing wrong when try to load the Jar? Could it be a Java version issue?

The zip also contained a ./conf folder with several XML, CSV, and SQL files.

I don't think you want to execute the .jars found in that .zip file. Instead, you should try using the Application.html found after extracting from the openempi-webapp-web-versionhere.war.
