You shouldn't normally need to specify a base URI explicitly in the query, it will be picked up automatically when you read the query from a file. And you can't refer to the base URI by putting "base-uri" at the start of your relative URI. URI resolution works the same way as in HTML: if A.xq and B.xq are in the same directory, then A can refer to the relative URI "B.xq"; if B.xq is in the parent directory of A, the relative URI can be "../B.xq" and so on. Alternatively use absolute URIs, which will normally be "file:///" followed by the full file name. (I guess "pclera" is the name of your machine? You don't need to specify that).

Sorry, I was a few days absent. Thank You for Your answaer. However, I've experimented, but it doesn't work. If I cut the host "pclera" from the uri, I get an error message, that the host "c" is unknown. If I use absolute URIs, my problem is not resolved. I can't connect to my library module file and I don't know what is the reason. Copying the library module file into the same path as the query file is, produce the same error. The parent path C:\rle is shared. I guess the problem maybe happens with namespaces or with the uri-String itself ... I is not a big problem, if I can't use a library module, but it was a little bit more elegant.

Here's a simple example that might help you get started and resolve your misunderstandings. In c:\temp\test.xq, enter: ======================== import module namespace foo="http://foo.com/" at "test.qmod"; foo:go() ======================== In c:\temp\test.qmod, enter: ======================== module namespace foo = "http://foo.com/"; declare function foo:go() as xs:string { "Go get it!" }; ======================== On the command line, do: java net.sf.saxon.Query c:\temp\test.xq The output should be <?xml version="1.0" encoding="UTF-8"?>Go get it! Saxon is resolving the relative module URI (after "at") against the base URI of the main module. Saxon knows this base URI because the query was supplied in a file with a known file name. If you supplied the query as a string, or from an anonymous Reader, then you would need to declare the base URI in the query prolog. Michael Kay Saxonica Limited

Thank You for Your help. Now it works! The reason was, that I have to use a relative URI in the "at"-location. Thanks Ralf.
