Change password for user in WebLogic 8.1 with Java

[Peter Denev]

Hi,
I need some help. I have the logic below to reset password for an user in WebLogic 8.1.

String url = request.getScheme() + "://" +
							request.getServerName() + ":" +
							request.getServerPort();
					Environment env = new Environment();
					env.setProviderUrl(url);
					Context ctx = env.getInitialContext();
					System.out.println("ctx: "+ctx);//DebugLog
					
					MBeanHome mbeanHome = (MBeanHome) ctx.lookup(MBeanHome.LOCAL_JNDI_NAME);
					System.out.println("mbeanHome: "+mbeanHome);//DebugLog
					
					DomainMBean domain = mbeanHome.getActiveDomain();
					System.out.println("domain: "+domain); //DebugLog
					
					SecurityConfigurationMBean secConf = domain.getSecurityConfiguration();
					RealmMBean realm = secConf.findDefaultRealm();
					AuthenticationProviderMBean authenticators[] = realm.getAuthenticationProviders();

					boolean changed = false;
					String lastErr = "";
					UserPasswordEditorMBean passwordEditorMBean = null;
					for (int i=0; i<authenticators.length; i++) {
						if (authenticators[i] instanceof UserPasswordEditorMBean) {
							passwordEditorMBean = (UserPasswordEditorMBean) authenticators[i];
							try {
								passwordEditorMBean.resetUserPassword(userName, newPass);
								changed = true;
							} catch (Throwable exc) {
								exc.printStackTrace();
								lastErr = exc.toString();
							}
						}
					}

Sometimes it crashes with this error:

<Password not changed due to an error. java.lang.Throwable at weblogic.rjvm.RJVMManager.findExisting(Ljava/net/InetAddress;ILweblogic/protocol/Protocol;)Lweblogic/rjvm/RJVM;(RJVMManager.java:322) at weblogic.rjvm.RJVMManager.findOrCreateRemoteInternal(Ljava/net/InetAddress;ILjava/lang/String;)Lweblogic/rjvm/RJVM;(RJVMManager.java:206) at weblogic.rjvm.RJVMManager.findOrCreate(Ljava/net/InetAddress;ILjava/lang/String;)Lweblogic/rjvm/RJVM;(RJVMManager.java:180) at weblogic.rjvm.RJVMFinder.findOrCreateRemoteServer(Ljava/net/InetAddress;I)Lweblogic/rjvm/RJVM;(RJVMFinder.java:223) at weblogic.rjvm.RJVMFinder.findOrCreate(Z)Lweblogic/rjvm/RJVM;(RJVMFinder.java:188) at weblogic.rjvm.ServerURL.findOrCreateRJVM(Z)Lweblogic/rjvm/RJVM;(ServerURL.java:125) at weblogic.jndi.WLInitialContextFactoryDelegate.getInitialContext(Lweblogic/jndi/Environment;Ljava/lang/String;)Ljavax/naming/Context;(WLInitialContextFactoryDelegate.java:296) at weblogic.jndi.Environment.getContext(Ljava/lang/String;)Ljavax/naming/Context;(Environment.java:166) at weblogic.jndi.Environment.getInitialContext()Ljavax/naming/Context;(Environment.java:145) at jsp_servlet.__changepassword._jspService(Ljavax/servlet/http/HttpServletRequest;Ljavax/servlet/http/HttpServletResponse;)V(__changepassword.java:243) at weblogic.servlet.jsp.JspBase.service(Ljavax/servlet/ServletRequest;Ljavax/servlet/ServletResponse;)V(Optimized Method) at weblogic.servlet.internal.ServletStubImpl$ServletInvocationAction.run()Ljava/lang/Object;(Optimized Method) at weblogic.security.acl.internal.AuthenticatedSubject.doAs(Lweblogic/security/subject/AbstractSubject;Ljava/security/PrivilegedAction;)Ljava/lang/Object;(Optimized Method) at weblogic.security.service.SecurityManager.runAs(Lweblogic/security/acl/internal/AuthenticatedSubject;Lweblogic/security/acl/internal/AuthenticatedSubject;Ljava/security/PrivilegedAction;)Ljava/lang/Object;(Optimized Method) at weblogic.servlet.internal.ServletStubImpl.invokeServlet(Ljavax/servlet/ServletRequest;Ljavax/servlet/ServletResponse;Lweblogic/servlet/internal/FilterChainImpl;)V(Optimized Method) at weblogic.servlet.internal.ServletStubImpl.invokeServlet(Ljavax/servlet/ServletRequest;Ljavax/servlet/ServletResponse;)V(Optimized Method) at weblogic.servlet.internal.WebAppServletContext$ServletInvocationAction.run()Ljava/lang/Object;(Optimized Method) at weblogic.security.acl.internal.AuthenticatedSubject.doAs(Lweblogic/security/subject/AbstractSubject;Ljava/security/PrivilegedAction;)Ljava/lang/Object;(Optimized Method) at weblogic.security.service.SecurityManager.runAs(Lweblogic/security/acl/internal/AuthenticatedSubject;Lweblogic/security/acl/internal/AuthenticatedSubject;Ljava/security/PrivilegedAction;)Ljava/lang/Object;(Optimized Method) at weblogic.servlet.internal.WebAppServletContext.invokeServlet(Lweblogic/servlet/internal/ServletRequestImpl;Lweblogic/servlet/internal/ServletResponseImpl;)V(Optimized Method) at weblogic.servlet.internal.ServletRequestImpl.execute(Lweblogic/kernel/ExecuteThread;)V(Optimized Method) at weblogic.kernel.ExecuteThread.execute(Lweblogic/kernel/ExecuteRequest;)V(Optimized Method) at weblogic.kernel.ExecuteThread.run()V(ExecuteThread.java:183) at java.lang.Thread.startThreadFromVM(Ljava/lang/Thread;)V(Unknown Source) >
