Hi I am trying to deploy JBoss-4.2.2.GA on HP-UX 11i v3 (B.11.31), and I get the following error: Caused by: java.lang.NoClassDefFoundError: org/jboss/security/auth/spi/UsernamePasswordLoginModule at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:620) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:124) at java.net.URLClassLoader.defineClass(URLClassLoader.java:260) at java.net.URLClassLoader.access$100(URLClassLoader.java:56) at java.net.URLClassLoader$1.run(URLClassLoader.java:195) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at org.jboss.mx.loading.RepositoryClassLoader.findClassLocally(RepositoryClassLoader.java:682) at org.jboss.mx.loading.RepositoryClassLoader.findClass(RepositoryClassLoader.java:662) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at org.jboss.mx.loading.RepositoryClassLoader.loadClassLocally(RepositoryClassLoader.java:200) at org.jboss.mx.loading.ClassLoadingTask$ThreadTask.run(ClassLoadingTask.java:131) at org.jboss.mx.loading.LoadMgr3.nextTask(LoadMgr3.java:399) at org.jboss.mx.loading.RepositoryClassLoader.loadClassImpl(RepositoryClassLoader.java:527) at org.jboss.mx.loading.RepositoryClassLoader.loadClass(RepositoryClassLoader.java:415) at java.lang.ClassLoader.loadClass(ClassLoader.java:251) at org.jboss.util.loading.DelegatingClassLoader.loadClass(DelegatingClassLoader.java:92) at org.jboss.mx.loading.LoaderRepositoryClassLoader.loadClass(LoaderRepositoryClassLoader.java:90) at java.lang.ClassLoader.loadClass(ClassLoader.java:251) at org.jboss.util.loading.DelegatingClassLoader.loadClass(DelegatingClassLoader.java:92) at java.lang.ClassLoader.loadClass(ClassLoader.java:251) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:246) at javax.security.auth.login.LoginContext.invoke(LoginContext.java:731) at javax.security.auth.login.LoginContext.access$000(LoginContext.java:186) at javax.security.auth.login.LoginContext$4.run(LoginContext.java:683) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.login.LoginContext.invokePriv(LoginContext.java:680) at javax.security.auth.login.LoginContext.login(LoginContext.java:579) at org.jboss.security.plugins.JaasSecurityManager.defaultLogin(JaasSecurityManager.java:603) at org.jboss.security.plugins.JaasSecurityManager.authenticate(JaasSecurityManager.java:537) at org.jboss.security.plugins.JaasSecurityManager.isValid(JaasSecurityManager.java:344) at org.jboss.ejb.plugins.SecurityInterceptor.checkSecurityAssociation(SecurityInterceptor.java:211) at org.jboss.ejb.plugins.SecurityInterceptor.invokeHome(SecurityInterceptor.java:135) at org.jboss.ejb.plugins.LogInterceptor.invokeHome(LogInterceptor.java:132) It seems like the JBoss classes are not loaded correctly. I have deployed already on the same machine JBoss-4.0.5.GA with no problem, and it is working fine. Doe anyone has any experince with it?
