In BioStar setting, all services are running(or Core Web Server service is not running) and nginx-service.log is leaving error msg below.


2019/05/27 16:56:35 => RunApp execute : C:\Program Files\Java\jreX.X.X_xxx\bin\java.exe, arg : java -jar biostar2-webapp.jar

2019/05/27 16:56:42 => JAVA_PATH: C:\Program Files\Java\jreX.X.X_xxx\bin\java.exe


FYI, nginx-service.log is in BioStar 2 installed folder/logs(eq.C:\Program Files\BioStar 2(x64)\logs)


Case 1. The wrong java path

If jreX.X.X_xxx is not match with the default java version in your environment, BioStar 2 web core service wouldn't start successfully. 

Please check if Java path is set correctly. 


- Open command window and result of 'java -version'

- Environment variables of 'JAVE_HOME'


Case 2. Corrupted files(eq. conf files etc) due to the wrong upgrade


If above version/path exists and match but the issue happens, then please go to BioStar 2 installed path and see what happens after commanding 'java -jar biostar2webapp.jar' manually and let me know the result(error msg).




If you couldn't resolve the issue with the same error message, please contact technical support team with information below.
