Currently we are in process of migrating application into Jboss EAP 5.1.0. While application trying to print log message using java.util.logging.Logger info() method, it is throwing NULL pointer exception. Please help me to resolve this issue: Sample code from app: import java.util.logging.Logger; public class sampleServlet { Logger debug = Logger.getAnonymousLogger(); debug.info("----------- start web stats ------------"); } Error message: 16:58:32,188 ERROR [[SSNValidationServlet]] Servlet.service() for servlet SSNValidationServlet threw exception java.lang.NullPointerException at org.apache.log4j.CategoryKey.<init>(CategoryKey.java:31) at org.apache.log4j.Hierarchy.getLogger(Hierarchy.java:261) at org.apache.log4j.Hierarchy.getLogger(Hierarchy.java:242) at org.apache.log4j.LogManager.getLogger(LogManager.java:188) at org.apache.log4j.Logger.getLogger(Logger.java:104) at org.jboss.logbridge.LogBridgeHandler.publish(LogBridgeHandler.java:71) at java.util.logging.Logger.log(Logger.java:458) at java.util.logging.Logger.doLog(Logger.java:480) at java.util.logging.Logger.log(Logger.java:503) at java.util.logging.Logger.info(Logger.java:1022) at com.putnaminv.corpapps.ElinkingApp.SSNValidationServlet.doPost(SSNValidationServlet.java:114) at javax.servlet.http.HttpServlet.service(HttpServlet.java:637) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:235) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:183) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:95) at org.jboss.web.tomcat.security.SecurityContextEstablishmentValve.process(SecurityContextEstablishmentValve.java:126) at org.jboss.web.tomcat.security.SecurityContextEstablishmentValve.invoke(SecurityContextEstablishmentValve.java:70) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:158) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:330) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:829) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:598) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:451) at java.lang.Thread.run(Thread.java:619) 16:59:59,314 INFO [ServerImpl] Runtime shutdown hook called, forceHalt: true 16:59:59,314 INFO [Http11Protocol] Pausing Coyote HTTP/1.1 on http-127.0.0.1-8080 -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/569502#569502] Start a new discussion in Beginner's Corner at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2075]
