Hi everybody, I am starting to use oXygen (20.1) with eXist-db (5.0RC4). I set up the datasource and can read and write to the database. When writing a new XQuery file, oXygen suggests .xquery as the file type extension and works fine with it. However, I am used to use .xq and .xqm for XQuery files. However, when I want to save such a file, oXygen refuses to save and shows the following errors: Cannot save the file: API error: Failed to invoke method uploadCompressed in class org.exist.xmlrpc.RpcConnection: Not in GZIP format This puzzles me and makes me think that somehow oXygen does not know about these file types, although they are indeed listed in Preferences->Filetype and associated with XQuery. Does anybody know what is going wrong here? Any help appreciated, Christian
