I'm searching a JBoss version with version 48.0 of servlet-api.jar. Currently, i've downloaded the JBoss 4.2.0.GA with version 49.0 of servlet-api.jar. Anyone can say me what is the right version for my problem ? [javac] bad class file: D:\jboss-4.2.0.GA\server\default\lib\servlet-api.jar(javax/servlet/http/HttpServletRequest.class) [javac] class file has wrong version 49.0, should be 48.0 [javac] Please remove or make sure it appears in the correct subdirectory of the classpath. [javac] import javax.servlet.http.HttpServletRequest; View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4050026#...
