i want create java webserver existing web hosting/space ip/port can test socket programming features. have webhosting package @ https://alfahosting.de/ possible socket programming webhosting package? if not possible socket programming webhosting package. how possible? special webhosting packages support socket programming own ip , port? i know if tutorial how set java webserver socket in web hosting package. thanks! most webhosting packages allow host static html pages , cgi (php, perl) scripts. provide jsp , jsf support more expensive regular webhosters. if want code own webserver/socket applications in java need root server package (i, example, use vserver €12,99/month) on such server have direct root access machine, can install software want - have install java runtime engine of choice , go (assuming server's firewall set correctly) - dedicated ip address can directly connect servers java programs.
