I would ask for 8.5.40 (or close) or 9.0.19 (or close). Those are the two currently support versions undergoing active development. Tomcat 7.0.x is still supported, but not much work is being done there anymore. >> What kind of access do you have for the server? If you have shell >> access, you can probably get the logs.

System.out.println usually goes to catalina.out, so you should already be all set. It's possible to redirect it on a per-context basis, but then it just goes into another file, also in the logs/ directory. Do you have any other log files in there alongside catalina.out? >> If you are using container-managed authentication (which is what >> Tomcat Realms provide), then you have to trust the hosting >> provider.

Your realm configuration is the least of your worries. - -chris -BEGIN PGP SIGNATURE- Comment: Using GnuPG with Thunderbird - https://www.enigmail.net/ iQIzBAEBCAAdFiEEMmKgYcQvxMe7tcJcHPApP6U8pFgFAlza7p0ACgkQHPApP6U8 pFjFuRAAuxbPAYClfZ24LuVwgWG4xlfAYww1ni7SPFr2wPXbUcQgB0ThPzYAegL6 3gA4Lzbx6u+ZTfVHdZr8AYCkudf0oBh9UoLU/7DHQTtgchsyUCVkIS3dNILlJlR0 4MG21YWcFNzzEIQ+N1jsupLZoojyd+vbzKdyNjCdPKzWbF3XVSfK8vhn+PEOGQPV eECPXtLslZqyiFpUHNBZm/lnnXvlH/3qV0Mjqe4GWSVS33NGAdJQRIWvQjxKi3rY TnBLspyb0PFUWZo4OwVTa8bkM7MLsMn6RhdrPWy1vIl34Jy8GkS+azO5MgYjVpCZ VWb+tFHNP4hcnFii0JsX5q5Ugb+F8WhugjzTvbJiQ0Rq9xCO0NRVcF6GJxnoD9NI 8EkB/uHfwI0DJCDl33azl8CoomNQ0Btnf+yIMNi4MVux8H76dXjzUDne1gASmNgi zuO/rDLSQ+0f4f1tflZV89KiwXvSMea3dNw9tRQ2vKQ0kdhp8fQ/oF7QHFURjFeM +OEWKfIz+DEmCbI20TqENutTLFb6YeTpVDVkiB2uih1LoXMkccoZFOgKKYARJDev x0qw3AX/PhHTPtBIaokJAQT1fWTcboD4FHHHLiQ8FpKTAjPHFzkOwoSUFEsiAXYM M3mdX40l5TrPnBvYRHons8gvVlmfIgA0p+1sbD0ngOpDEd7iA4k= =/ZG2 -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Re: Does Tomcat server printout System.out.print infor?
It is pretty normal. If you don't want to deal with the systems administration of your server, you can lease a tomcat instance and deploy your war file. A host will typically help you with some of the configuration and management, and notify you if you have deployed some naughty code that is consuming server resources. This is somewhere in between a WUSIWUG and a fill cloud server instance of, say, Linux.

Does Tomcat server printout System.out.print infor?
Hello experts, Currently, I am uploading a new .war file up to my hosting company. However, I am puzzled how things work and would like to check what is the norm out there. They are using httpd apache server and tomcat. Basically, I have subscribed a private Tomcat server so I get an instance of Tomcat server - 8.0.27. But, the re-start of server is not in my control. I would like to know if this is the normal environment in a web hosting company ? Another thing is that, in my newly uploaded war file, I don't get to see any System.out.println infor in my code, which I believe it should be printed out, as per my last log file indication in the web hosting company. What they told me is "Only if there is system level operation. For example, unloading/reloading a war file would have logged." So, please help me know if it is not possible to see system.out.print infor as what I have put in the code in my java class ? Another thing is that I am going to put in the Tomcat Realm for the log-in module and I am wondering where is the privacy since I do not have the full control over Tomcat in this web hosting environment ?
