JBoss 5.1.0 EAP. Randomly Occurs java.lang.NoClassDefFoundError

Question

In our EJB 3.0 application, we have a random event java.lang.NoClassDefFoundError.

It just happens locally in the IDE.

Setup:

OS: Windows 7 32 Bit Java JDK: 1.6.0_24 (32 Bit)‎ IDE: IntelliJ 11.1‎ App-Server: JBoss 5.1.0 EAP EAR-Building with „maven-ear-plugin"‎ WAR-Building with Maven „<packaging>war</packaging>"‎ EJB-Building with Maven „<packaging>ejb</packaging>" und „maven-ejb-‎plugin"‎ 

EAR is as follows:

 xxx.ear ‎ |___ META-INF ‎ | |___ application.xml (Information about EAR, EJB und WEB-Modul ‎configured)‎ ‎ |‎ ‎ |___ xxxEJB.jar‎ ‎ | |‎ ‎ | |___ META-INF ‎ | | |___ persistance.xml (JPA 1.0 configuration)‎ ‎ | | |___ jboss.xml (JBoss-Config)‎ ‎ | | |___ ejb-jar.xml (EJB 3.0 definition)‎ ‎ | |‎ ‎ | |___ country/yyy/xxx/.. (our own compiled classes) ‎ | |___ report/.. (JasperReport-Tamplates) ‎ | |___ quickfix/.. (QuickFixJ-configuration) ‎ | |___ all dependent libraries for our EJB 3.0 project, (74-jar-files) ‎ | ‎ ‎ |___ xxxWAR.war‎ ‎ |‎ ‎ |___ META-INF ‎ |___ WEB-INF ‎ |‎ ‎ |___ lib‎ ‎ | |___ all dependent libraries for the Servlet-‎project, (2-jar-files) ‎ |___ classes‎ ‎ | |___ country/yyy/xxx/.. (our own compiled classes) ‎ |___ web.xml (Servlet-configuration)‎ 

Stacktrace is as follows:

The JVM starts with the option: -verbose: class to see all the actions for loading classes.

The file "org / joda / time / tz / DefaultNameProvider" is definitely located in the jar file: file: file: / C: / Workarea / Projects / xxx-trunk / xxx- ear / target / xxx.ear! /XxxEJB.jar

Suggestions:

We have a feeling that Quartz has something to do with it. Therefore, when something was planned, from EJB 3.0 Remote-Stateless-Service. Sometimes an error occurs.

Quartz-Scheduler is initially created in the context of the Servlet-Context, but basically it works fine.

Has anyone had the same problem?

JBoss deployment is done through the IntelliJ JBoss plugin:

Maybe the problem is related to the deployment mechanism used? we are deploying an application with the IntelliJ JBoss plugin, so JBoss says:

 09:39:21,614 INFO [MainDeployer] deploy, url=file:/C:/Workarea/Projects/xxx-trunk/xxx-ear/target/xxx.ear 09:39:33,613 INFO [Ejb3DependenciesDeployer] Encountered deployment AbstractVFSDeploymentContext@2726974 {vfszip:/C:/Workarea/Projects/xxx-trunk/xxx-ear/target/xxx.ear/xxxEJB.jar/} 

Answer 1

The problem only occurs when deploying with IntelliJ IDEA JBoss-Run-Configuration.

Thanks to user1516873 for the hint to deploy manually through ANT / Maven.

We have tried this.

We introduced ANT -Task to simply copy the xxx.ear artifact into the JBoss-Deploy folder. It has been working fine ever since, and we don't have java.lang.NoClassDefFoundError yet.

build.xml is as follows:

 <project name="xxx-deploy"> <!-- Copy Artifact to JBoss-Deploy-Folder --> <target name="xxx-ear-deploy"> <copy file="C:/Workarea/Projects/xxx-trunk/xxx-ear/target/xxx.ear" todir="C:/Workarea/_tools/jboss-eap-5.1.0-xxx/jboss-as/server/default/deploy"/> </target> </project> 

Answer 2

Perhaps this is due to a jar conflict inside the binary (xx.ear). You can use the code below to find out the jar duplication in the lib folder of the ear folder

public class JarSearch {

 public static final String NL = System.getProperty("line.separator"); public static String directory = new String(); public static File file; public static Writer output; public static void main(String args[]) { /*if (args.length != 2){ System.out.println("You must provide 1. search directory and 2. search string"); System.exit(0); }*/ JarSearch search = new JarSearch(); try{ String dir = "E://lib";//path of lib folder directory = dir; file = new File(directory); String parentPath = file.getParent(); parentPath += "\\JarSearchResult.txt"; file = new File(parentPath); //output = new BufferedWriter(new FileWriter(file)); String searchStr = "DES.class";// name of class file to b searched search.searchDir(dir, searchStr);//"C:\\Program Files\\IBM\\Application Developer\\plugins\\com.ibm.etools.ctc.binding.java\\runtime\\ctcjava.jar"); }catch(IOException ioe){ System.out.println(ioe.toString()); } } public static void searchDir(String dirName, String searchStr)throws IOException{ File dir = new File(dirName); if (!dir.isDirectory()){ throw new IOException(dir+" is not a directory !!!"); } File files[] = dir.listFiles(); for (int i=0; i<files.length; i++){ if (files[i].isDirectory()){ searchDir(files[i].getAbsolutePath(), searchStr); }else{ if (files[i].getName().endsWith(".jar")){ searchFile(files[i].getAbsolutePath(), searchStr); } } } //output.close(); } public static void searchFile(String fileName, String searchStr)throws IOException{ //System.out.println("File Absolute Path :: " + fileName); boolean outputMessage = false; StringBuffer buf = new StringBuffer(); int index1 = fileName.lastIndexOf("\\"); int index2 = fileName.lastIndexOf("/"); //System.out.println(index1 + " :: " + index2 + " ===>>> " + NL); int index = -1; if (index1 > index2){ index = index1; } else { index = index2; } buf.append(NL); buf.append("DIR: "); buf.append(fileName.substring(0, index)); buf.append(NL); buf.append("JAR: "); buf.append(fileName.substring(index+1)); buf.append(NL); searchStr = searchStr.toLowerCase(); JarFile jar = new JarFile(fileName); Enumeration e = jar.entries(); while (e.hasMoreElements()){ JarEntry entry = (JarEntry)e.nextElement(); String strEntry = entry.getName().toLowerCase(); //System.out.println(strEntry); if (strEntry.indexOf(searchStr) > -1){ outputMessage = true; buf.append(entry.getName()); buf.append(NL); } } if (outputMessage){ System.out.println(buf); //output.write(buf.toString()); } }
