New thread error to call FileFolderServiceImpl

liveljack

Hi all,
A new method was added to FileFolderServiceImpl, and it run pretty well. But when I am trying to call it from a new thread in EditContentPropertiesDialog. The AuthenticationCredentialsNotFoundException error is thrown. I cannot find what's wrong, could any of you please be kind enough to help me out of this?

Thanks a lot!
The exception stack is like the following:

Each thread has its own authentication context and it looks like you have not initialised it.
On the new thread use the AuthenticationUtils class to "RunAs" the same user as your "current thread".

Also, depending upon your requirement, you may be able to use the internal "fileFolderService" spring bean, note the little F, since that bean will not have permission checking.

Thanks mrogers a lot, the new function in FileFolderService could be called successfully now. The codes are like the following:

class ThumbnailGenerateThread extends Thread{
        FileFolderService ffservice;
        NodeRef noderef;
        public ThumbnailGenerateThread(FileFolderService service, NodeRef node){
            this.ffservice = service;
            this.noderef = node;
        }

        public void run(){
            RunAsWork<Object> thumbGeneWork = new RunAsWork<Object>()
            {
                public Object doWork() throws Exception
                {
                    System.out.println("before generation of ThumbnailGenerateThread");
                    ffservice.generaThumbnail(noderef);
                    System.out.println("after generation of ThumbnailGenerateThread");
                    return null;
                }
            };
          AuthenticationUtil.runAs(thumbGeneWork, AuthenticationUtil.SYSTEM_USER_NAME);
        }
    }

But I have got another problem while calling the newly added "generaThumbnail" function. The error is like

Is there any reason why the transaction is marked as rollback-only? Please~~

liveljack

Could anyone be kind enough to check this problem, please?

There's a problem somewhere which is resulting in an exception being thrown. Then later on you try to commit the transaction rather than rolling it back. The key to solving this is to find out where the first exception is occurring. It's usually caused by code incorrectly swallowing exceptions.
