WildFly 8 - Sabuwar Sabar Aikace-aikacen JBoss don Linux

Kamar yadda muka sani cewa JBoss AS an sake masa suna zuwa WildFly. An ƙara sabbin abubuwa da yawa kuma an haɓaka da yawa. A ƙarshe WildFly 8.0.0 Final an sake shi a kan Fabrairu 11.2014. WildFly Project Lead Jason Greene ya sanar da haka.

WildFly 8 shine Red Hat's Java EE 7 uwar garken buɗaɗɗen tushen aikace-aikacen sabar. Babban fasali sune kamar haka:

Babban canji a cikin wannan shine cewa yanzu WildFly 8 shine Certified Java EE7.

Undertow sabon sabar gidan yanar gizo ce mai girma da aka rubuta cikin Java. Yanzu an aiwatar da wannan a cikin WildFly 8. Wannan da gaske an tsara shi don babban kayan aiki da haɓakawa kuma yana iya ɗaukar miliyoyin haɗin gwiwa. Tsarin rayuwar Undertow gaba ɗaya yana sarrafa shi ta aikace-aikacen sakawa.
