• Some services refusing to start on Win 7 machine. What could the root cause be?

  - by BombDefused

  When I check msconfig, there are no services that are blocked from starting up. When I look in services.msc, the problem services have a start up type of 'Automatic', but have a blank space where others will show 'Started'. Attempting to start them manually results in the following pop up error messages. I have no idea what's causing this, looks like some sort of cascade effect from another problem service. It's affecting scheduled tasks, SQL server agent and windows back up services. How can I resolve this? I don't know how to work out what the root cause is. Task Scheduler Service Start Error: "Windows could not start the Task Scheduler service on local computer. 1068: The dependecy service or group failed to start. SQL Server Service Start Error: "The SQL Server Agent service on Local Computer started and then stopped. Some services stop automatically if they are not in use by other services or programs." UPDATE: I've just noticed some other services have a description of "Failed to Read Description. Error Code: 2" They are: NetMsmqActivator, NetPipeActivator, NetTcpActivator, NetTcpPortSharing UPDATE 2: As joeqwerty says the Event Log service does seem to be the root of the problem. This service will not start either. It fails with 'Error 31 - A device attached to the system is not functioning correctly'. I've tried detaching all devices. I've also followed the advice here, where the same problem is described, but with no luck: http://social.technet.microsoft.com/Forums/en/w7itprosecurity/thread/44479c49-55e6-4bd7-b25e-3f2a6497306e Update 3 @ Pacey - The following was a good tip, really clear instruction. However, I found that those reg keys do not exist on my system. "Your Problem might also derive from the UpperFilter or LowerFilter Settings of the CDROM Drive. These are a known cause for Errorcode 31. You can find step-by-step instructions on removing the filters on about.com" I followed the advice through to checking every component in device manager separately, but everything is reported as working correctly!? These services did all work at one point. The hardware set up hasn't changed much. Guess I'm looking at a repair install maybe???!

• SecurityException when accessing (ejb2-) session bean via local interface in JBoss 5

  - by sme

  I have the following problem with an EJB 2 SessionBean when deploying in JBoss 5: The SessionBean (called LVSKeepAliveDispatcher) requires a specific user role (called "LVSUser"), specified by <method-permission > <description></description> <role-name>LVSUser</role-name> <method > <description></description> <ejb-name>LVSKeepAliveDispatcher</ejb-name> <method-name>*</method-name> </method> </method-permission> in ejb-jar.xml. I now want to access this SessionBean from a Service (i.e. a class implementing the org.jboss.varia.scheduler.Schedulable interface that is then registered as a service) running inside the same JBoss instance. This is my jboss-service.xml: <server> <mbean code="org.jboss.varia.scheduler.Scheduler" name="lvs:service=TranslationService"> <attribute name="StartAtStartup">true</attribute> <attribute name="SchedulableClass">de.repower.lvs.server.service.translation.TranslationService</attribute> <attribute name="SchedulableArguments"></attribute> <attribute name="SchedulableArgumentTypes"></attribute> <attribute name="InitialStartDate">NOW</attribute> <attribute name="SchedulePeriod">60000</attribute> <attribute name="InitialRepetitions">1</attribute> <attribute name="TimerName">jboss:service=Timer,name=TranslationServiceTimer</attribute> <depends><mbean code="javax.management.timer.Timer" name="jboss:service=Timer,name=TranslationServiceTimer"/></depends> <depends>jboss.j2ee:service=EJB,jndiName=de/repower/lvs/i18n/sessionbeans/LVSTranslation</depends> </mbean> As the service is deployed in the same vm as the session bean I want to call the session bean via the local interface, but I get a SecurityException when I try to create an instance. When instead I do a lookup of the RemoteInterface it works. This is the code inside the perform method of my service class: public void perform(Date now, long remainingRepetitions) { try { final UsernamePasswordHandler handler = new UsernamePasswordHandler(USERNAME, PASSWORD); final LoginContext lc = new LoginContext("client-login", handler); lc.login(); // Trying to instantiate an LVSKeepAliveDispatcher via remote interface // This part works LVSKeepAliveDispatcher localvHome = LVSKeepAliveDispatcherUtil.getHome().create(); LOGGER.info("Successfully instantiated an LVSKeepAliveDispatcher " + localvHome.toString()); // Trying to instantiate an LVSKeepAliveDispatcherLocal via local interface LVSKeepAliveDispatcherLocal localvLocalHome = LVSKeepAliveDispatcherUtil.getLocalHome().create(); // this code is unforunately never reached LOGGER.info("Successfully instantiated an LVSKeepAliveDispatcherLocal " + localvLocalHome.toString()); lc.logout(); } catch (final Exception ex) { LOGGER.error("Error: ", ex); } } Exception: 2009-02-17 10:38:02,266 INFO [lvsi18n] (Timer-2) Successfully instantiated an LVSKeepAliveDispatcher de/repower/lvs/server/service/alive/sessionbeans/LVSKeepAliveDispatcher:Stateless 2009-02-17 10:38:02,297 ERROR [org.jboss.ejb.plugins.SecurityInterceptor] (Timer-2) Error in Security Interceptor java.lang.SecurityException: Authentication exception, principal=internalSystemUser at org.jboss.ejb.plugins.SecurityInterceptor.checkSecurityContext(SecurityInterceptor.java:321) at org.jboss.ejb.plugins.SecurityInterceptor.process(SecurityInterceptor.java:243) at org.jboss.ejb.plugins.SecurityInterceptor.invokeHome(SecurityInterceptor.java:205) at org.jboss.ejb.plugins.security.PreSecurityInterceptor.process(PreSecurityInterceptor.java:136) at org.jboss.ejb.plugins.security.PreSecurityInterceptor.invokeHome(PreSecurityInterceptor.java:88) at org.jboss.ejb.plugins.LogInterceptor.invokeHome(LogInterceptor.java:132) at org.jboss.ejb.plugins.ProxyFactoryFinderInterceptor.invokeHome(ProxyFactoryFinderInterceptor.java:107) at org.jboss.ejb.SessionContainer.internalInvokeHome(SessionContainer.java:639) at org.jboss.ejb.Container.invoke(Container.java:1046) at org.jboss.ejb.plugins.local.BaseLocalProxyFactory.invokeHome(BaseLocalProxyFactory.java:362) at org.jboss.ejb.plugins.local.LocalHomeProxy.invoke(LocalHomeProxy.java:133) at $Proxy193.create(Unknown Source) at de.repower.lvs.server.service.translation.TranslationService.perform(TranslationService.java:68) at org.jboss.varia.scheduler.Scheduler$PojoScheduler.invoke(Scheduler.java:1267) at org.jboss.varia.scheduler.Scheduler$BaseListener.handleNotification(Scheduler.java:1235) at sun.reflect.GeneratedMethodAccessor281.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.jboss.mx.notification.NotificationListenerProxy.invoke(NotificationListenerProxy.java:153) at $Proxy87.handleNotification(Unknown Source) at javax.management.NotificationBroadcasterSupport.handleNotification(NotificationBroadcasterSupport.java:257) at javax.management.NotificationBroadcasterSupport$SendNotifJob.run(NotificationBroadcasterSupport.java:322) at javax.management.NotificationBroadcasterSupport$1.execute(NotificationBroadcasterSupport.java:307) at javax.management.NotificationBroadcasterSupport.sendNotification(NotificationBroadcasterSupport.java:229) at javax.management.timer.Timer.sendNotification(Timer.java:1234) at javax.management.timer.Timer.notifyAlarmClock(Timer.java:1203) at javax.management.timer.TimerAlarmClock.run(Timer.java:1286) at java.util.TimerThread.mainLoop(Timer.java:512) at java.util.TimerThread.run(Timer.java:462) To further diagnose the error I debugged through the SecurityInterceptor and found that in the first case (successful creating an instance via the remote interface) the security context "lvs-security" (which I defined in login-config.xml) is being used whereas in the second case (failure when creating an instance via the local interface) the generic security context "CLIENT-LOGIN" is being used. This is the definition of the securit context "lvs-security" in login-config.xml: <application-policy name = "lvs-security"> <authentication> <login-module code = "org.jboss.security.ClientLoginModule" flag = "required"> </login-module> <login-module code = "de.repower.lvs.security.UsersRolesLoginModule" flag = "sufficient"> </login-module> <login-module code = "de.repower.lvs.security.login.LVSLoginModule" flag = "required"> <module-option name = "lvs-jboss-host">localhost</module-option> <module-option name = "lvs-jboss-jndi-port">1099</module-option> </login-module> </authentication> </application-policy> I'm now kind of stuck and hope someone can give me a hint about where to further look for the cause of the problem. This worked fine in JBoss 3.2.7. Edit: My current workaround for this problem: create a new container configuration in jboss.xml and remove the security interceptor stuff from this configuration use this newly created container configuration for all my session beans that I only use locally (i.e. via local interface).

• WCF to WCF communication 401, HttpClient

  - by youwhut

  I have a WCF REST service that needs to communicate with another WCF REST service. There are three websites: Default Web Site Website1 Website2 If I set up both services in Default Web Site and connect to the other (using HttpClient) using the URI http://localhost/service then everything is okay. The desired set-up is to move these two services to separate websites and rather than using the URI http://localhost/service, accessing the service via http://website1.domain.com/service still using HttpClient. I received the exception: System.ArgumentOutOfRangeException: Unauthorized (401) is not one of the following: OK (200), Created (201), Accepted (202), NonAuthoritativeInformation (203), NoContent (204), ResetContent (205), PartialContent (206) I can see this is a 401, but what is going on here? Thanks

• Workflow foundation 4.0 message correlation and error reporting

  - by Lygpt

  I have a workflow service that runs and performs a number of different operations (such as web service calls). If one of these operations fails I call an error reporting web service to notify a seperate system that one of my workflow operations has failed. As the error could be something like the web service being down, I loop and retry this operation until it works. There can be times though when the data I'm passing to this web service is faulty and it needs changing. So I need to be able to hook into this running (but delayed) workflow and change local workflow variables and then re-run the operation. I've looked at message correlation in workflow 4.0 to achieve this but because the delay activity is active in my running workflow instance, any second service call doesn't do anything (it's like the delay activity is blocking any other requests). I've tried setting 'CanCreateInstance' to both true and false but it doesn't help. Thanks!

• Upload a file to SharePoint through the built-in web services

  - by Andy McCluggage

  What is the best way to upload a file to a Document Library on a SharePoint server through the built-in web services that version WSS 3.0 exposes? Following the two initial answers... We definitely need to use the Web Service layer as we will be making these calls from remote client applications. The WebDAV method would work for us, but we would prefer to be consistent with the web service integration method. There is additionally a web service to upload files, painful but works all the time. Are you referring to the “Copy” service? We have been successful with this service’s CopyIntoItems method. Would this be the recommended way to upload a file to Document Libraries using only the WSS web service API? I have posted our code as a suggested answer.

• Multiple WCF windows services on the same box - endpoint configuration

  - by David Belanger

  Hi, I have 2 windows services installed on a machine with different service names, they install and start fine. What's happening is that they're both listening to the same endpoints and thus competing for messages. I've tried to change the baseAddress to be different for both services without success. Here's my service host config: <configuration> <appSettings> <add key="ServiceName" value="Service - Service Host 1"/> </appSettings> <system.serviceModel> <bindings> <wsHttpBinding> <binding name="NoSecurityBinding"> <security mode="None"> <message establishSecurityContext="false"/> <transport clientCredentialType="None"/> </security> </binding> </wsHttpBinding> <basicHttpBinding> <binding name="NoSecurityBinding"> <security mode="None"> <transport clientCredentialType="None"/> </security> </binding> </basicHttpBinding> </bindings> <services> <service name="Lib.Interface.Service" behaviorConfiguration="Lib.Interface.ServiceBehavior"> <host> <baseAddresses> <add baseAddress="http://localhost:8000/Service"/> </baseAddresses> </host> <endpoint address="" binding="basicHttpBinding" bindingConfiguration="NoSecurityBinding" contract="Lib.Interface.IService"/> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> </service> </services> <behaviors> <serviceBehaviors> <behavior name="Lib.Interface.ServiceBehavior"> <serviceMetadata httpGetEnabled="True" policyVersion="Policy12"/> <serviceDebug includeExceptionDetailInFaults="False"/> </behavior> </serviceBehaviors> </behaviors> Any idea how I could set up the services (other than unique service names) so they're not conflicting with one another? Thanks.

• Program seems to get stuck ?

  - by Frank

  I have a Java program, I did some change and the strange thing is no matter what I do now, it will output the same result before my change, I looked into my system (Windows Vista), and clicked on "Generate a system health report", the result says : Symptom : A service is reported as having an unexpected error code Cause : One or more services has failed. The service did not stop gracefully, suggesting the service may have crashed or one of its components stopped in an unsupported way. Details : Service exited with code not equal to 0 or 1077 Resolution : Restart the service It doesn't say which service, and I defragmented my drives a few times, it still gave me the same report. I also checked my memory, it says no problem with ram. Everything else is ok, I re-started the windows a few times, got more free space on my C: drive, yet the Java program is still not responding to my new changes, unless I intentionally make a mistake, it gives me compile error, but if it can compile successfully, it still gives me the results before the change. What can I do to fix this ? Frank

• WCF Rest services for use with the repository pattern?

  - by mark smith

  Hi there, I am considering moving my Service Layer and my data layer (repository pattern) to a WCF Rest service. So basically i would have my software installed locally (WPF client) which would call the Service Layer that exists via a Rest Service... The service layer would then call my data layer using a WCF Rest Service also OR maybe just call it via the DLL assembly I was hoping to understand what the performance would be like. Currently I have my datalayer and servicelayer installed locally via DLL Assemblies locally on the pc. Also i presume the WCF REST services won't support method overloading hance the same name but with a different signature?? I would really appreciate any feedback anyone can give. Thanks

• WCF Web Services - Multiple Hop impersonation on the same server

  - by Lerxst

  Hi Folks I have 3 web services, all located on the same server. My Client calls Service A, which impersonates the client to call Service B, and all is well. Now, I want to impersonate the caller of service B (which is my username) to call Service C. When I use the same technique as before (AllowedImpersonationLevel = Impersonate, user.Impersonate()), The user doesnt get passed to service C. Instead, Service C sees the user as the user I am running it under in IIS. Is there anything special I need to do to get this working? Is this a delegation issue? (I thought it would not be delegation because they are all on the same server) Thanks SO!

• Starting self hosted WCF services on demand

  - by Pieter

  Is it possible to start self hosted WCF services on demand? I see two options to accomplish this: Insert a listener in the self hosted WCF's web server and spin up a service host when a request for a specific service comes in, before WCF starts looking for the existence of that endpoint; or Integrate a web service in process, start a service host for a request if it isn't running yet and redirect the request to that service host (like I suspect IIS does). I cannot use IIS or WAS because the web services need to run in process with the UI business logic. Which is feasible and how can I accomplish this? EDIT: I cannot just start the service hosts because there are hundreds, most (about 95%) of which are (almost) never used but need to be available. This is for exposing a business logic layer of 900 entities.

• C# DLL Deployed in COM+. Error while accessing the methods.

  I have the C# Dll (ABService) deployed in COM + and my os Is windows 2008. I have given the strong name for this dll and its dependent dll’s When I access the method of this dll through localhost or if I add the reference to the client project the method are executed successfully. Simply if I access the dll from the same machine with the reference it is working. So I think there is no problem with the way I deployed in the COM +. I have the doubt whether I have the problem in OS and Visual Studio 2008 combination. I have built all the dll with the Visual Studio 2008 with Target cpu as x86 and targert framework as 2.0. I have given in below the codes I have tried with and the errors. I need to create the object for the dll in server machine(64 bit) and access its method from the client(32 bit) Code : Type svr = Type.GetTypeFromProgID("ABService.Service", strserver1url[2],false); ABService.Service service1= (ABService.Service)Activator.CreateInstance(svr); strresult = service1.ExecuteService(orequest.xml); Error :{"Retrieving the COM class factory for remote component with CLSID {77BF00E0-41AC-3967-9E72-A4927CC0B880} from machine 10.105.138.64 failed due to the following error: 80040154."} Code Type svr = Type.GetTypeFromProgID("ABService.Service", strserver1url[2],true); object Service1 = null; Service1 = (ABService.Service)Activator.CreateInstance(svr, true); strresult = Convert.ToString(ReflectionHelper.Invoke(Service1, "ExecuteService", new object[] { orequest.xml })); Service1 = null; Error: Retrieving the COM class factory for remote component with CLSID {77BF00E0-41AC-3967-9E72-A4927CC0B880} from machine ftpsite failed due to the following error: 80040154. With the below code instead of C#.Net dll if i have the vb dll in Com + the method is executed successfully. Code ords = new RDS.DataSpace(); ords.InternetTimeout = 600000; object M_Service = null; ABService.Service oabservice = null; M_Service = ords.CreateObject("ABService.Service",url); strresult = Convert.ToString(ReflectionHelper.Invoke(M_Service, "ExecuteService", new object[] { orequest.xml })); Error : {"Object doesn't support this property or method 'ExecuteService'"} Code object obj=Interaction.CreateObject("ABService.Service", "10.105.138.64"); strresult = Convert.ToString(ReflectionHelper.Invoke(obj, "ExecuteService", new object[] { orequest.xml })); Error: {"Cannot create ActiveX component."} Code object obj = Activator.GetObject(typeof(ABService.Service), @"http://10.105.138.64:80/ABANET"); strresult = Convert.ToString(ReflectionHelper.Invoke(obj, "ExecuteService", new object[] { orequest.xml })); Error: InnerException {"The remote server returned an error: (405) Method Not Allowed."} System.Exception {System.Net.WebException} Message "Exception has been thrown by the target of an invocation.”

  We have a thread program that sends bulk mail. The information like 1. To 2. Subject Etc., are fetched from database, mail is composed and pushed to SMTP server. One of our customer sent a bulk mail with 2390 email.

• How to efficiently implement a blocking call with Rails, while letting the client wait for the reply

  - by Kyle Heironimus

  We have a web service written in Rails. The API is published and we cannot change it. Our app communicates with a remote web service that sometimes hangs or takes several seconds to reply. Client -> Our Web Service -> Remote Web Service Currently, if the remote web service hangs for 5 seconds, one of our rails processes on our web service also hangs with it, which is what we need to avoid. I've seen things such as mod-x-sendfile, modporter, and delayed jobs, but the best I can tell, they all assume the client is not waiting for an answer. Since the API is already established, we cannot tell the client "I'm attempting to do what you want, check back later for the answer." The best option we have come up with so far is to add a second, non-rails web server running eventmachine to process these particular calls. Is there a better way?

• Multiple windows services in a single project = mystery

  - by Remoh

  I'm having a bizarre issue that I haven't seen before and I'm thinking it MUST be something simple that I'm not seeing in my code. I have a project with 2 windows services defined. One I've called DataSyncService, the other SubscriptionService. Both are added to the same project installer. Both use a timer control from System.Timers. If I start both services together, they seem to work fine. The timers elapse at the appropriate time and everything looks okay. However, if I start either service individually, leaving the other stopped, everything goes haywire. The timer elapses constantly and on the wrong service. In other words, if I start the DataSyncService, the SubscriptionService timer elapses over and over. ...which is obviously strange. The setup is similar to what I've done in the past so I'm really stumped. I even tried deleting both service and starting over but it doesn't seem to make a difference. At this point, I'm thinking I've made a simple error in the way I'm defining the services and my brain just won't let me see it. It must be creating some sort of threading issue that causes one service to race when the other is stopped. Here the code.... From Program.cs: static void Main() { ServiceBase[] ServicesToRun; ServicesToRun = new ServiceBase[] { new DataSyncService(), new SubscriptionService() }; ServiceBase.Run(ServicesToRun); } From ProjectInstaller.designer.cs: private void InitializeComponent() { this.serviceProcessInstaller1 = new System.ServiceProcess.ServiceProcessInstaller(); this.dataSyncInstaller = new System.ServiceProcess.ServiceInstaller(); this.subscriptionInstaller = new System.ServiceProcess.ServiceInstaller(); // // serviceProcessInstaller1 // this.serviceProcessInstaller1.Account = System.ServiceProcess.ServiceAccount.LocalSystem; this.serviceProcessInstaller1.Password = null; this.serviceProcessInstaller1.Username = null; // // dataSyncInstaller // this.dataSyncInstaller.DisplayName = "Data Sync Service"; this.dataSyncInstaller.ServiceName = "DataSyncService"; this.dataSyncInstaller.StartType = System.ServiceProcess.ServiceStartMode.Automatic; // // subscriptionInstaller // this.subscriptionInstaller.DisplayName = "Subscription Service"; this.subscriptionInstaller.ServiceName = "SubscriptionService"; this.subscriptionInstaller.StartType = System.ServiceProcess.ServiceStartMode.Automatic; // // ProjectInstaller // this.Installers.AddRange(new System.Configuration.Install.Installer[] { this.serviceProcessInstaller1, this.dataSyncInstaller, this.subscriptionInstaller}); } private System.ServiceProcess.ServiceProcessInstaller serviceProcessInstaller1; private System.ServiceProcess.ServiceInstaller dataSyncInstaller; private System.ServiceProcess.ServiceInstaller subscriptionInstaller; From DataSyncService.cs: public static readonly int _defaultInterval = 43200000; //log4net.ILog log; public DataSyncService() { InitializeComponent(); //log = LogFactory.Instance.GetLogger(this); } protected override void OnStart(string[] args) { timer1.Interval = _defaultInterval; //GetInterval(); timer1.Enabled = true; EventLog.WriteEntry("MyProj", "Data Sync Service Started", EventLogEntryType.Information); //log.Info("Data Sync Service Started"); } private void timer1_Elapsed(object sender, System.Timers.ElapsedEventArgs e) { EventLog.WriteEntry("MyProj", "Data Sync Timer Elapsed.", EventLogEntryType.Information); } private void InitializeComponent() { this.timer1 = new System.Timers.Timer(); ((System.ComponentModel.ISupportInitialize)(this.timer1)).BeginInit(); // // timer1 // this.timer1.Enabled = true; this.timer1.Elapsed += new System.Timers.ElapsedEventHandler(this.timer1_Elapsed); // // DataSyncService // this.ServiceName = "DataSyncService"; ((System.ComponentModel.ISupportInitialize)(this.timer1)).EndInit(); } From SubscriptionService: public static readonly int _defaultInterval = 300000; //log4net.ILog log; public SubscriptionService() { InitializeComponent(); } protected override void OnStart(string[] args) { timer1.Interval = _defaultInterval; //GetInterval(); timer1.Enabled = true; EventLog.WriteEntry("MyProj", "Subscription Service Started", EventLogEntryType.Information); //log.Info("Subscription Service Started"); } private void timer1_Elapsed(object sender, System.Timers.ElapsedEventArgs e) { EventLog.WriteEntry("MyProj", "Subscription Service Time Elapsed", EventLogEntryType.Information); } private void InitializeComponent() //in designer { this.timer1 = new System.Timers.Timer(); ((System.ComponentModel.ISupportInitialize)(this.timer1)).BeginInit(); // // timer1 // this.timer1.Enabled = true; this.timer1.Elapsed += new System.Timers.ElapsedEventHandler(this.timer1_Elapsed); // // SubscriptionService // this.ServiceName = "SubscriptionService"; ((System.ComponentModel.ISupportInitialize)(this.timer1)).EndInit(); } Again, the problem is that the timer1_elapsed handler runs constantly when only one of the services is started. And it's the handler on the OPPOSITE service. Anybody see anything?
