Hi, I tried to implement a singleton pattern for my already working lucene object. But there is a strange error when I tried to access the instance.
When my Singleton GetInstance() method is executed for the first time it creates a new instance of my lucene object. There are some member variables in this object like an IndexWriter and IndexReader. These objects are created in the constructor and I can access them directly in the constructor successfully. GetInstance() now returns this lucene object and I have to execute some operations on it. But the IndexWriter seems to be closed meanwhile and I got the exception: "org.apache.lucene.store.AlreadyClosed Exception: this IndexWriter is closed" when my object tries to writer some documents. How could this happen? Isn't it possible to use lucene with a singleton-pattern? Kind regards, D.
