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;
