Trying to install rapidminer server on one of our nodes. When I try to execute the java file and type "java -jar rapidminer-server-installer-7.2.0.jar", I get the following error "no main manifest attribute, in rapidminer-server-installer-7.2.0.jar". Any help or suggestions on how to fix this? Thank you.

    Hi,

     

    that is what the start scripts are for in the /bin folder. They prepare the environment and call the .jar with the following line (example for Windows):

    "%JAVA_EXE%" %DEFAULT_JVM_OPTS% %JAVA_OPTS% %RAPIDMINER_SERVER_INSTALLER_OPTS% -classpath "%CLASSPATH%" com.rapidminer.server.installer.Starter %CMD_LINE_ARGS%

     

    So please use either the provided Linux or Windows scripts to correctly start the installer. Simply calling the .jar file is unfortunately not quite enough.

     

    Regards,

    Marco
