Hi Charles. Yes, it is. I created C:\src to put source code there. I compiled that souce code, and the DLLs go to the bin\debug subdirectory. > I realize it's long, but can you post the full string? Trying to reproduce this error, I noticed to my surprise that it wouldn't occur. It turns out that the error only occurs for some of the DLLs. libdb_java46d.dll # can be in java.library.path or PATH libdbxml_java24d.dll # ditto libdb46d.dll # must reside in a PATH directory libdbxml24d.dll # ditto xerces-c_2_8D.dll # ditto xqilla21d.dll # ditto The Java bridge DLLs (or whatever they're called) can be moved to a directory only contained in java.library.path, but not in PATH. The other libraries must be in a PATH directory in order to be loaded. > > So I guess there is something wrong with Tomcat here. So I now guess I was wrong here, and of course you were right. Sorry for blaming Tomcat. The problem seems to be with how the libdb(xml)_java libraries load other libraries. So this is probably related to BDB and the Windows API, or the build - but not to Tomcat. > I can't see how, unless there's something really odd going on with the > classloader hierarchy.

Here's a stack trace, in case you still think it is relevant. The error message mentions the *_java library, but I think this is only because that library has a dependency on the libdb46, and that one isn't found, which the error message does not reveal.
