• ASMX: What should tempuri.org be replaced with?

  - by JL

  Every new web service you create using visual studio comes with a predefined namespace like this: [WebService(Namespace = "http://tempuri.org/")] My web service will run at different clients, and on different domains, so because of this I don't know the domain upfront during development, also I don't want to have to edit this file, each time I deploy to a new client. What exactly should the value of Namespace be? It seems like a web address, but that doesn't make sense to me. Please explain. Thanks

• How to get a Token from a Lucene TokenStream?

  - by FarmBoy

  I'm trying to use Apache Lucene for tokenizing, and I am baffled at the process to obtain Tokens from a TokenStream. The worst part is that I'm looking at the comments in the JavaDocs that address my question. http://lucene.apache.org/java/3_0_1/api/core/org/apache/lucene/analysis/TokenStream.html#incrementToken%28%29 Somehow, an AttributeSource is supposed to be used, rather than Tokens. I'm totally at a loss. Can anyone explain how to get token-like information from a TokenStream?
