  • Using Doctype in Nhibernate

    - by sukh
    Hi I am trying to keep common properties of base class in one location and use XML ENTITY to refer in Nhibernate mapping file. Mapping file <?xml version="1.0" encoding="utf-8" ?> <!DOCTYPE hibernate-mapping [ <!ENTITY BasePropertyList SYSTEM "BasePropertyList.xml"> ]> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="Model" namespace= "Model" default-lazy="false"> <class name="DerivedClass"> &BasePropertyList; </class> </hibernate-mapping> BasePropertyList.xml <id name="ID" column="ID" type="Int32" unsaved-value="0"> <generator class="native"></generator> </id> <property name="CreatedDate" update="false" /> <property name="CreatedBy" update="false" /> <property name="LastModifiedDate" /> <property name="LastModifiedBy" /> I am getting following exception System.Xml.XmlException : DTD is prohibited in this XML document. at NHibernate.Cfg.Configuration.LogAndThrow(Exception exception) Am I missing anything here? How DOCTYPE works in Nhibernate mapping file??

  • Create 2 connection pools using c3p0 in Jetty

    - by Mike
    Hello, I'm trying to set up a maven web project that runs Jetty. In this project, I need 2 JNDIs... my plan is to configure 2 connection pools using c3p0 in Jetty. So, I created WEB-INF/jetty-env.xml, and I have the following:- <Configure class="org.mortbay.jetty.webapp.WebAppContext"> <New id="ds1" class="org.mortbay.jetty.plus.naming.Resource"> <Arg>jdbc/ds1</Arg> <Arg> <New class="com.mchange.v2.c3p0.ComboPooledDataSource"> // ... JTDS to SQL Server - omitted for brevity </New> </Arg> </New> <New id="ds2" class="org.mortbay.jetty.plus.naming.Resource"> <Arg>jdbc/ds2</Arg> <Arg> <New class="com.mchange.v2.c3p0.ComboPooledDataSource"> // ... JTDS to Sybase - omitted for brevity </New> </Arg> </New> </Configure> When I run jetty, I get this exception:- May 14, 2010 1:16:56 PM com.mchange.v2.c3p0.impl.AbstractPoolBackedDataSource getPoolManager INFO: Initializing c3p0 pool... com.mchange.v2.c3p0.ComboPooledDataSource [ acquireIncrement -> ... ... ... Exception in thread "com.mchange.v2.async.ThreadPoolAsynchronousRunner$PoolThread-#0" java.lang.LinkageError: net.sourceforge.jtds.jdbc.DefaultProperties at java.lang.ClassLoader.defineClassImpl(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:258) It seems to me that I can't create 2 connection pools using c3p0. If I remove either one of the connection pool, it worked. What am I doing wrong? How do I create 2 connection pools in Jetty? Thanks much.

  • how to create wizard forms in ruby on rails

    - by Branden Silva
    I'm trying to understand the best options for pulling off a wizard form in ruby on rails. Ideally I'd like to have it so the application signup has a back and next button that allows the user to submit data in steps. So in step 1 they could fill out contact info. Once they are done they could click next and be on step 2 to fill out payment info, etc. If they make a mistake, they can click back and correct it. Some steps will be required, while others will not, but you do have to make it to the last step to submit the data to the database to sign up. They then need the ability to go back and fill out the past steps in the same fashion after completion. (example: perhaps if they clicked on a profile link they could recomplete the steps in the same fashion because they didn't want to complete all the steps right away. Maybe by being given a skip button before they completed the steps to sign up?). I also need validation to happen on what steps have been completed preventing them from moving onto the next step until corrected or completed. Option 1) I've noticed that ajax has been recommended as an option in other questions on stackoverflow. The only problem I have with it is that the user would not be able to sign up if javascript was disabled. Ideally I'd like to have it be native to ruby on rails but I'm willing to work with whatever is necessary to get it to work.

  • Question - Setting dynamic HTML using Javascript to iFrames on Windows Mobile 6.1 - IE Mobile6

    - by swaroop
    Hi Experts, (excuse me if this is not the right forum to post - i couldn't find anything related to non-native programming and related to this topic) I Am trying to set a dynamic HTML into an iFrame on the webpage. I have tried a couple of things but none of them seem to work. I m able to read the innerHTML but can't seem to update it. // Able to read using document.getElementById('iFrameIdentifier').innerHTML; // On Desktop IE, this code works document.getElementById('iFrameId').contentWindow.document.open(); document.getElementById('iFrameId').contentWindow.document.write(dynamicHTML); document.getElementById('iFrameId').contentWindow.document.close(); Ideally the same function should work as how it works for div's but it says 'Object doesn't support this method or property". I have also tried document.getElementById('iFrameId').document.body.innerHTML. This apparently replaces the whole HTML of the page and not just the innerHTML. I have tried out a couple of things and they didn't work document.getElementById('iFrameId').body.innerHTML document.frames[0].document.body.innerHTML My purpose is to have a container element which can contain dynamic HTML that's set to it. I've been using it well till now when I observed that the setting innerHTML on a div is taking increasing amount of time because of the onClicks or other JS methods that are attached to the anchors and images in the dynamic HTML. Appears the JS methods or the HTML is some how not getting cleaned up properly (memory leak?) Also being discussed - http://www.experts-exchange.com/Programming/Languages/Scripting/JavaScript/Q_26185526.html#a32779090

  • LinkageError thrown when attempting to pass instance of class between 2 eclipse plugins

    - by Ed
    I have found many people with simliar issues but no soultions...basically I have two eclipse plug-ins that both in ther class path rely on the same jar. The UI plug-in replies on the Driver plug-in (implementing a custom ODA driver and UI for it). Both rely on a jar containing some other classes of mine and is called plugin-dto.jar When the UI plug-in calls a method on one of the classes in the Driver plug-in that returns an object whose class is found in the plugin-dto jar I get the error: java.lang.LinkageError: Class com/test/reporting/NrDsDriverProvider violates loader constraints at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:620) at org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader.defineClass(DefaultClassLoader.java:183) at org.eclipse.osgi.baseadaptor.loader.ClasspathManager.defineClass(ClasspathManager.java:576) at org.eclipse.osgi.baseadaptor.loader.ClasspathManager.findClassImpl(ClasspathManager.java:546) at org.eclipse.osgi.baseadaptor.loader.ClasspathManager.findLocalClassImpl(ClasspathManager.java:477) at org.eclipse.osgi.baseadaptor.loader.ClasspathManager.findLocalClass_LockClassLoader(ClasspathManager.java:465) at org.eclipse.osgi.baseadaptor.loader.ClasspathManager.findLocalClass(ClasspathManager.java:445) at org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader.findLocalClass(DefaultClassLoader.java:211) at org.eclipse.osgi.internal.loader.BundleLoader.findLocalClass(BundleLoader.java:381) at org.eclipse.osgi.internal.loader.BundleLoader.findClassInternal(BundleLoader.java:457) at org.eclipse.osgi.internal.loader.BundleLoader.findClass(BundleLoader.java:410) at org.eclipse.osgi.internal.loader.BundleLoader.findClass(BundleLoader.java:398) at org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader.loadClass(DefaultClassLoader.java:105) at java.lang.ClassLoader.loadClass(ClassLoader.java:251) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319) Any ideas how I get around this issue?

  • Delphi: Alternative to using Assign/ReadLn for text file reading

    - by Ian Boyd
    i want to process a text file line by line. In the olden days i loaded the file into a StringList: slFile := TStringList.Create(); slFile.LoadFromFile(filename); for i := 0 to slFile.Count-1 do begin oneLine := slFile.Strings[i]; //process the line end; Problem with that is once the file gets to be a few hundred megabytes, i have to allocate a huge chunk of memory; when really i only need enough memory to hold one line at a time. (Plus, you can't really indicate progress when you the system is locked up loading the file in step 1). The i tried using the native, and recommended, file I/O routines provided by Delphi: var f: TextFile; begin Assign(filename, f); while ReadLn(f, oneLine) do begin //process the line end; Problem withAssign is that there is no option to read the file without locking (i.e. fmShareDenyNone). The former stringlist example doesn't support no-lock either, unless you change it to LoadFromStream: slFile := TStringList.Create; stream := TFileStream.Create(filename, fmOpenRead or fmShareDenyNone); slFile.LoadFromStream(stream); stream.Free; for i := 0 to slFile.Count-1 do begin oneLine := slFile.Strings[i]; //process the line end; So now even though i've gained no locks being held, i'm back to loading the entire file into memory. Is there some alternative to Assign/ReadLn, where i can read a file line-by-line, without taking a sharing lock? i'd rather not get directly into Win32 CreateFile/ReadFile, and having to deal with allocating buffers and detecting CR, LF, CRLF's. i thought about memory mapped files, but there's the difficulty if the entire file doesn't fit (map) into virtual memory, and having to maps views (pieces) of the file at a time. Starts to get ugly. i just want Assign with fmShareDenyNone!

  • How to scale a sprite image without losing color key information?

    - by Michael P
    Hello everyone, I'm currently developing a simple application that displays map and draws some markers on it. I'm developing for Windows Mobile, so I decided to use DirectDraw and Imaging interfaces to make the application fast and pretty. The map moves when user moves finger on the touchscreen, so the whole map moving/scrolling animation has to be fast, but it is not. On every map update I have to draw portion of the map, control buttons, and markers - buttons and markers are preloaded on DirectDraw surface as a mipmap. So the only thing I do is BitBlit from the mipmap to a back buffer, and from the back buffer to a primary surface (I can't use page flipping due to the windowed mode of my application). Previously I used premultiplied-alpha surface with 32 bit ARGB pixel format for images mipmap, everything was looking good, but drawing entire "scene" was horribly slow - i could forget about smooth map scrolling. Now I'm using mipmap with native (RGB565) pixel format and fuchsia (0xFF00FF) color key. Drawing is much better my mipmap surface is generated on program loading - images are loaded from files, scaled (with filtering) and drawn on mipmap. The problem is, that image scaling process blends pixel colors, and those pixels which are on the border of a sprite region are blended with surrounding fuchsia pixels resulting semi-fuchsia color that is not treated as color key. When I do blitting with color key option, sprites have small fuchsia-like borders, and it looks really bad. How to solve this problem? I can use alpha blitting, but it is too slow - even in ARGB 1555 format.

  • jvm version for Websphere 6.1.0.23on Solaris

    - by dr jerry
    Hi I'm at big financial institute and we've an application running on Websphere 6.1. on Solaris. Due to MQ Connectivity we had to install fixpack 6.1.0.23. Unfortunately this broke an ejb (1.1) which is still there as legacy (Test missed it). [3/23/10 11:33:18:703 CET] 00000055 EJBContainerI E WSVR0068E: Attempt to start EnterpriseBean EventRisk_1.0.0#EventRiskEJB.jar#PolicyDataManager failed with exception: java.lang.NoSuchMethodError: com.ibm.ejs.csi.ResRefListImpl.(Lorg/eclipse/jst/j2ee/ejb/EnterpriseBean;Lcom/ibm/ejs/models/base/bindings/ejbbnd/EnterpriseBeanBinding;Lcom/ibm/ejs/models/base/extensions/ejbext/EnterpriseBeanExtension;)V at com.ibm.ws.metadata.ejb.EJBMDOrchestrator.finishBMDInit(EJBMDOrchestrator.java:1364) at com.ibm.ws.runtime.component.EJBContainerImpl.finishDeferredBeanMetaData(EJBContainerImpl.java:4829) at com.ibm.ws.runtime.component.EJBContainerImpl$3.run(EJBContainerImpl.java:4631) at java.security.AccessController.doPrivileged(Native Method) at com.ibm.ws.security.util.AccessController.doPrivileged(AccessController.java:125) at com.ibm.ws.runtime.component.EJBContainerImpl.initializeDeferredEJB(EJBContainerImpl.java:4627) at com.ibm.ejs.container.HomeOfHomes.getHome(HomeOfHomes.java:390) at com.ibm.ejs.container.HomeOfHomes.internalCreateWrapper(HomeOfHomes.java:938) at com.ibm.ejs.container.EJSContainer.createWrapper(EJSContainer.java:4783) at com.ibm.ejs.container.WrapperManager.faultOnKey(WrapperManager.java:545) at com.ibm.ejs.util.cache.Cache.findAndFault(Cache.java:498) at com.ibm.ejs.container.WrapperManager.keyToObject(WrapperManager.java:489) We cannot reproduce the issue on our desktop boxes (it all works fine there) and we do not have direct access to our the Solaris machines (dependent on the deployment department) we do suspect a discrepancy on the jvm but we're not sure. My question is two fold: can you confirm IBM's statement that fixpack 6.1.0.23 for solaris indeed runs on jvm 1.5.0_17b04 our installation tells us ./java -version java version "1.5.0_13" But deploy department is not eager to investigate. Do you see some other solution, apart from hiring big blue's con$ultancy? kind regards, Jeroen.

  • Help! I've learned jQuery... now I want to learn JavaScript

    - by Derek Adair
    I am a self-taught web developer/programmer. I started out about two years ago by learning how to make simple dynamic websites with HTML/CSS/PHP. Then I started dabbling with animation... Enter jQuery I've become quite proficient with jQuery over the last year and I've even started making my own plugins. I've spent most of my effort learning how to beautify websites with fancy effects and what not. Upon tackling my first full-blown application, I realized how under-developed my knowledge of JavaScript actually is. jQuery has allowed me to rely on its framework so heavily that I rarely use any interesting functions, techniques, or whatever that are 'native' to the JavaScript language. For example: I have a basic understanding of what a closure is... but I am unsure where this technique can actually benefit me. Although as I understand it, that's what my jQuery plugins do with (function ($){//plugin code here})(jQuery). I've seen many posts/blogs/whatever about memory leaks and circular references which is concerning. I'm frustrated because I can wrap my head around the basic concepts of what these are just by reading the articles, but I'm finding that the deeper I go the more I don't understand. The vocabulary alone is burdensome. Let alone how to actually use these techniques/functions/language features. I am trying to figure out what I don't know I'm looking to gather any advice, techniques, articles, books, videos, snippets, examples, potential pitfalls... really anything you have regarding application development with JavaScript/jQuery.

  • How to create a variadic (with variable length argument list) function wrapper in JavaScript

    - by U-D13
    The intention is to build a wrapper to provide a consistent method of calling native functions with variable arity on various script hosts - so that the script could be executed in a browser as well as in the Windows Script Host or other script engines. I am aware of 3 methods of which each one has its own drawbacks. eval() method: function wrapper () { var str = ''; for (var i=0; i<arguments.lenght; i++) str += (str ?', ':'') + ',arguments['+i+']'; return eval('[native_function] ('+str+')'); } switch() method: function wrapper () { switch (arguments.lenght) { case 0: return [native_function] (arguments[0]); break; case 1: return [native_function] (arguments[0], arguments[1]); break; ... case n: return [native_function] (arguments[0], arguments[1], ... arguments[n]); } } apply() method: function wrapper () { return [native_function].apply([native_function_namespace], arguments); } What's wrong with them you ask? Well, shall we delve into all the reasons why eval() is evil? And also all the string concatenation... Not a solution to be labeled "elegant". One can never know the maximum n and thus how many cases to prepare. This also would strech the script to immense proportions and sin against the holy DRY principle. The script could get executed on older (pre- JavaScript 1.3 / ECMA-262-3) engines that don't support the apply() method. Now the question part: is there any another solution out there?

  • Hooking thread exit

    - by mackenir
    Is there a way for me to hook the exit of managed threads (i.e. run some code on a thread, just before it exits?) I've developed a mechanism for hooking thread exit that works for some threads. Step 1: develop a 'hook' STA COM class that takes a callback function and calls it in its destructor. Step 2: create a ThreadStatic instance of this object on the thread I want to hook, and pass the object a managed delegate converted to an unmanaged function pointer. The delegate then gets called on thread exit (since the CLR calls IUnknown::Release on all STA COM RCWs as part of thread exit). This mechanism works on, for example, worker threads that I create in code using the Thread class. However, it doesn't seem to work for the application's main thread (be it a console or windows app). The 'hook' COM object seems to be deleted too late in the shutdown process and the attempt to call the delegate fails. (The reason I want to implement this facility is so I can run some native COM code on the exiting thread that works with STA COM objects that were created on the thread, before it's 'too late' (i.e. before the thread has exited, and it's no longer possible to work with STA COM objects on that thread.))

  • Safari Extension Questions

    - by Rob Wilkerson
    I'm in the process of building my first Safari extension--a very simple one--but I've run into a couple of problems. The extension boils down to a single, injected script that attempts to bypass the native feed handler and redirect to an http:// URI. My issues so far are twofold: The "whitelist" isn't working the way I'd expect. Since all feeds are shown under the "feed://" protocol, I've tried to capture that in the whitelist as "feed://*/*" (with nothing in the blacklist), but I end up in a request loop that I can't understand. If I set blacklist values of "http://*/*" and "https://*/*", everything works as expected. I can't figure out how to access my settings from my injected script. The script creates a beforeload event handler, but can't access my settings using the safari.extension.settings path indicated in the documentation. I haven't found anything in Apple's documentation to indicate that settings shouldn't be available from my script. Since extensions are such a new feature, even Google returns limited relevant results and most of those are from the official documentation. What am I missing? Thanks.

  • Using git submodules in a git-svn project

    - by Matthias
    In our git-svn managed project, we have 3 upstream projects that are all kept in native git repositories on GitHub. Since the source code of those upstream projects is under our control and changes frequently, our current solution, namely re-deploying the build artifacts to the super-project everytime we change something is quite cumbersome. What I'd like to have is this: parent project (git-svn): --> submodule 1 (git) --> submodule 2 (git) --> submodule 3 (git) That way, the source code for submodules 1-3 is compiled along with the sources for the super project, but I can push changes to submodules separately. The question is: what happens when I git svn dcommit on the parent project? Does this even work? UPDATE Hm, I just set up a simple project structure, trying to resemble this scenario, and I receive this error message when trying to dcommit on the superproject: a0301b11f3544a1e71067ff270eded65e4c8afbd doesn't exist in the repository at /opt/local/libexec/git-core/git-svn line 4775 Failed to read object a0301b11f3544a1e71067ff270eded65e4c8afbd at /opt/local/libexec/git-core/git-svn line 574 Any ideas/suggestions?

  • Why calling Process.killProcess(Process.myPid()) is a bad idea?

    - by Tal Kanel
    I've read some posts saying using this method is "not good", shouldn't been use, it's not the right way to "close" the application and it's not how android works... I understand and accept the fact that Android OS knows better then me when it's the right time to terminate the process, but I didn't heard yet a good explanation why it's wrong using the killProcess() method?. after all - it's part of the android API... what I do know is that calling this method while other threads doing in potential an important work (operations on files, writing to DB, HTTP requests, running services..) can be terminated in the middle, and it's clearly not good. also I know I can benefit from the fact that "re-open" the application will be faster, cause the system maybe still "holds" in memory state from last time been used, and killProcess() prevents that. beside this reason, in assumption I don't have such operations, and I don't care my application will load from scratch each run, there are other reasons why not using the killProcess() method? I know about finish() method to close an Activity, so don't write me about that please.. finish() is only for Activity. not to all application, and I think I know exactly why and when to use it... and another thing - I'm developing also games with the Unity3D framework, and exporting the project to android. when I decompiled the generated apk, I was very suprised to find out that the java source code created from unity - implementing Unity's - Application.quit() method, with Process.killProcess(Process.myPid()). Application.quit() is suppose to be the right way to close game according to Unity3d guides (is it really?? maybe I'm wrong, and missed something), so how it happens that the Unity's framework developers which doing a very good work as it seems implemented this in native android to killProcess()? anyway - I wish to have a "list of reasons" why not using the killProcess() method, so please write down your answer - if you have something interesting to say about that. TIA

  • TLS with SNI in Java clients

    - by ftrotter
    There is an ongoing discussion on the security and trust working group for NHIN Direct regarding the IP-to-domain mapping problem that is created with traditional SSL. If an HISP (as defined by NHIN Direct) wants to host thousands of NHIN Direct "Health Domains" for providers, then it will an "artificially inflated cost" to have to purchase an IP for each of those domains. Because Apache and OpenSSL have recently released TLS with support for the SNI extension, it is possible to use SNI as a solution to this problem on the server side. However, if we decide that we will allow server implementations of the NHINDirect transport layer to support TLS+SNI, then we must require that all clients support SNI too. OpenSSL based clients should do this by default and one could always us stunnel to implement an TLS+SNI aware client to proxy if your given programming language SSL implementation does not support SNI. It appears that native Java applications using OpenJDK do not yet support SNI, but I cannot get a straight answer out of that project. I know that there are OpenSSL Java libraries available but I have no idea if that would be considered viable. Can you give me a "state of the art" summary of where TLS+SNI support is for Java clients? I need a Java implementers perspective on this.

  • What are alternatives to Win32 PulseEvent() function?

    - by Bill
    The documentation for the Win32 API PulseEvent() function (kernel32.dll) states that this function is “… unreliable and should not be used by new applications. Instead, use condition variables”. However, condition variables cannot be used across process boundaries like (named) events can. I have a scenario that is cross-process, cross-runtime (native and managed code) in which a single producer occasionally has something interesting to make known to zero or more consumers. Right now, a well-known named event is used (and set to signaled state) by the producer using this PulseEvent function when it needs to make something known. Zero or more consumers wait on that event (WaitForSingleObject()) and perform an action in response. There is no need for two-way communication in my scenario, and the producer does not need to know if the event has any listeners, nor does it need to know if the event was successfully acted upon. On the other hand, I do not want any consumers to ever miss any events. In other words, the system needs to be perfectly reliable – but the producer does not need to know if that is the case or not. The scenario can be thought of as a “clock ticker” – i.e., the producer provides a semi-regular signal for zero or more consumers to count. And all consumers must have the correct count over any given period of time. No polling by consumers is allowed (performance reasons). The ticker is just a few milliseconds (20 or so, but not perfectly regular). Raymen Chen (The Old New Thing) has a blog post pointing out the “fundamentally flawed” nature of the PulseEvent() function, but I do not see an alternative for my scenario from Chen or the posted comments. Can anyone please suggest one? Please keep in mind that the IPC signal must cross process boundries on the machine, not simply threads. And the solution needs to have high performance in that consumers must be able to act within 10ms of each event.

  • Weblogic 10.3.0 : Loosing a stateless session bean in the bean pool

    - by KlasE
    Hi, We have a strange situation where we loose a Stateless SessionBean in a Bean Pool in Weblogic 10.3.0 Since we only have one bean in the pool, this effectively hangs all incoming calls. We do not want more than one instance in the pool because of application restrictions. In the Weblogic admin console, we can see that there are 1 instance in the bean pool, 0 beans in use and 1 waiting incoming request. The question is, what can have caused the system to not send the request to the one obviously free bean instance? This happens after several hours and over 100000 incoming requests, and the same scenario worked fine in the old weblogic 8 environment. We get the following stacktrace: "[ACTIVE] ExecuteThread: '5' for queue: 'weblogic.kernel.Default (self-tuning)'" waiting for lock java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject@b0d484 TIMED_WAITING sun.misc.Unsafe.park(Native Method) java.util.concurrent.locks.LockSupport.parkNanos(LockSupport.java:198) java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject.await(AbstractQueuedSynchronizer.java:2054) weblogic.ejb.container.pool.StatelessSessionPool.waitForBean(StatelessSessionPool.java:269) weblogic.ejb.container.pool.StatelessSessionPool.getBean(StatelessSessionPool.java:111) weblogic.ejb.container.manager.StatelessManager.preInvoke(StatelessManager.java:148) weblogic.ejb.container.internal.BaseRemoteObject.preInvoke(BaseRemoteObject.java:227) weblogic.ejb.container.internal.StatelessRemoteObject.preInvoke(StatelessRemoteObject.java:52) com.mycompany.beans.MessageLogFacace_n73y0z_EOImpl.isMyStuffValid(MessageLogFacace_n73y0z_EOImpl.java:261) com.mycompany.beans.MessageLogFacace_n73y0z_EOImpl_WLSkel.invoke(Unknown Source) weblogic.rmi.internal.BasicServerRef.invoke(BasicServerRef.java:589) weblogic.rmi.cluster.ClusterableServerRef.invoke(ClusterableServerRef.java:230) weblogic.rmi.internal.BasicServerRef$1.run(BasicServerRef.java:477) weblogic.security.acl.internal.AuthenticatedSubject.doAs(AuthenticatedSubject.java:363) weblogic.security.service.SecurityManager.runAs(Unknown Source) weblogic.rmi.internal.BasicServerRef.handleRequest(BasicServerRef.java:473) weblogic.rmi.internal.wls.WLSExecuteRequest.run(WLSExecuteRequest.java:118) weblogic.work.ExecuteThread.execute(ExecuteThread.java:201) weblogic.work.ExecuteThread.run(ExecuteThread.java:173) Any help would be very welcome.
