Java.lang.noclassdeffounderror: Org/slf4j/loggerfactory
vote favorite 1 Im having a problem on a Spring based webapp that is being deployed to Websphere and interacts with IBM MQ. All is fine until I try some failure tests. While the webapp is up and running, I stop IBM MQ. I then invoke the webapp to send a JMS message out. The webapp hung at the call to JmsTemplate.convertAndSend and the following exception was found in the ffdc directory. Note the JmsTemplate was initialised using the JNDIObjectFactoryBean where it had got the MQ Connection Factory settings from Websphere. Can anyone explain the reason behind the "Initializaton Failure" ??

Unanswered question This question has not been answered yet. Hi, We have an existing application written in WPF 6.1.5.2 which is working fine and as expected. We have a change request to add https://www.ibm.com/developerworks/community/forums/html/topic?id=d5945014-62e5-494b-a1e5-ab191b2a6e05 some functionality in to this application which involves including a new set of JAR files (written by us) to allow us to add this in. When we build and deploy our application with these JARs (and other JARs which are dependencies) we are getting the following error: com.ibm.websphere.servlet.error.ServletErrorReport: java.lang.NoClassDefFoundError: com.bowstreet.util.XmlUtil (initialization failure) at com.ibm.ws.webcontainer.servlet.ServletWrapper.service(ServletWrapper.java:1762) at com.ibm.ws.webcontainer.servlet.ServletWrapper.service(ServletWrapper.java:1595) at com.ibm.ws.webcontainer.filter.WebAppFilterChain.doFilter(WebAppFilterChain.java:104) at com.ibm.ws.webcontainer.filter.WebAppFilterChain._doFilter(WebAppFilterChain.java:77) at com.ibm.ws.webcontainer.filter.WebAppFilterManager.doFilter(WebAppFilterManager.java:895) at com.ibm.ws.webcontainer.servlet.ServletWrapper.handleRequest(ServletWrapper.java:932) at com.ibm.ws.webcontainer.servlet.ServletWrapper.handleRequest(ServletWrapper.java:500) at com.ibm.ws.webcontainer.servlet.ServletWrapperImpl.handleRequest(ServletWrapperImpl.java:178) at com.ibm.ws.webcontainer.webapp.WebApp.handleRequest(WebApp.java:3810) at com.ibm.ws.webcontainer.webapp.WebGroup.handleRequest(WebGroup.java:276) at com.ibm.ws.webcontainer.WebContainer.handleRequest(WebContainer.java:931) at com.ibm.ws.webcontainer.WSWebContainer.handleRequest(WSWebContainer.java:1583) at com.ibm.ws.webcontainer.channel.WCChannelLink.ready(WCChannelLink.java:183) at com.ibm.ws.http.channel.inbound.impl.HttpInboundLink.handleDiscrimination(HttpInboundLink.java:455) at com.ibm.ws.http.channel.inbound.impl.HttpInboundLink.handleNewInformation(HttpInboundLink.java:384) at com.ibm.ws.http.channel.inbound.impl.HttpInboundLink.ready(HttpInboundLink.java:272) at com.ibm.ws.tcp.channel.impl.NewConnectionInitialReadCallback.sendToDiscriminators(NewConnectionInitialReadCallback.java:214) at com.ibm.ws.tcp.channel.impl.NewConnectionInitialReadCallback.complete(NewConnectionInit
java.lang.NoClassDefFoundError: How to resolve - Part 3 7/10/2012 Pierre-Hugues Charbonneau 4 comments This is part 3 http://javaeesupportpatterns.blogspot.com/2012/07/javalangnoclassdeffounderror-how-to.html of our java.lang.NoClassDefFoundError troubleshooting series. As I mentioned in my first http://tech.thecoolblogs.com/2010/11/javalangnoclassdeffounderror.html article, there are many possible problems that can lead to java.lang.NoClassDefFoundErrorsuch as a wrong Java runtime classpath. This article will describe one of the most common causes of this problem: failure of Java class static initializer blocks or static variables. A sample Java program will error 500 be provided and I encourage you to compile and run this example from your workstation in order to properly replicate and understand this type of problem. Java static initializer revisited The Java programming language provides you with the capability to "statically" initialize variables or a block of code. This is achieved via the "static" variable error 500 java.lang.noclassdeffounderror identifier or the usage of a static {} block at the header of a Java class. Static initializers are guaranteed to be executed only once in the JVM life cycle and are Thread safe by design which make their usage quite appealing for static data initialization such as internal object caches, loggers etc. What is the problem? I will repeat again, static initializers are guaranteed to be executed only once in the JVM life cycle…This means that such code is executed at the class loading time and never executed again until you restart your JVM. Now what happens if the code executed at that time (@Class loading time) terminates with an unhandled Exception? Welcome to the java.lang.NoClassDefFoundError problem case #2! NoClassDefFoundError problem case 2 - static initializer failure This type of problem is occurring following the failure of static initializer code combined with successive attempts to create a new instance of the affected (non-loaded) class. Sample Java program ** A tutorial video is now available:http://www.youtube.com/watch?v=h

Check the below points 1) Check the constructor and make sure there is nothing which could throw a Runtime exception 2) Check the body of the class and see if there is a possibility of NullPointer or any other Runtime exception while assigning value to the fields Mostly this could happen when you are assgning values to static fields which might not resolve properly while class loading.

That helped me with the issue that I was struggling for 3 days. I was thinking the classloader is not finding the class but it is finding but there were Runtime issue within the class.Thanks again.ReplyDeleteishitaJanuary 19, 2012 at 11:52 AMBut what u did to solve this issue as I m getting the same error after giving login/password to login pageReplyDeleteSriJanuary 28, 2012 at 8:43 AMHi Ishita, I didnt understand your question. Can you please elaborate?ReplyDeleteAnonymousJune 5, 2012 at 5:37 AMThanks.. it works !!! The problem was there was a NullPointer in the static block.RegardsYogeshyogesh249@gmail.comReplyDeleteAdd commentLoad more...
