Error starting Web sphere 8.5 application server

Recently, Websphere 8.5 application server has been corrupted. I receive the below error while starting the server. Have uninstalled the server completely and reinstalled again. Tried to start the server from startServer.bat in IBM\WebSphere\AppServer\bin folder.

I don't see any errors in the server logs

Thanks for the help in advance

ClassNotFoundException: Files/microsoft

Something in your launch command needs quotation marks around it - something is pointing at a path within "Program Files\Microsoft " but does not have it within quotes, so Java sees the spaces and thinks "Files\Microsoft" is its own argument to Java. Presumably, this is before the actual Java class that launches the server, so Java reads it as the main class it should launch, and it fails because you obviously don't have a class called "Files\Microsoft".

Creating a launch script was an excellent move. Open quickServerStart.bat and search for "Program Files\Microsoft", determine where the quotation marks need to be in order to keep that whole argument together, add them, and see if that gets your server up and running. If you're able to do that, at least you're functional while you fix your configuration.

Given what you've shared of the failure, my guess is that the issue is a JVM argument added to the server process. Ideally, if you can get the server to start using the generated launch script, you can fix it through the admin console (it'd be in the Server -> Process Definition -> Java Virtual Machine page). If you can't get the server to launch, then you'll want to go to the config/cells/(cellname)/nodes/(nodename)/servers/(servername) directory and hand-edit server.xml (back up the file first!). Again, search for "Program Files\Microsoft" and determine whether it actually belongs there, and if so, where you can add surrounding quotation marks to make it into a contained argument.

Best of luck!
