Discussion Database on Linux Server

I just downloaded and installed xphwt.nsf. After replicating it my server, I try to hit this URL:

http://ohcmhsrv026.interstell.home/articles/xphwt.nsf

This browser displays this error message:

Unexpected runtime error

The runtime has encountered an unexpected error.

Error source

Page Name:/page1.xsp

Exception

Unable to open database: xphwt.nsf because: Database xphwt.nsf cannot be opened

Database xphwt.nsf cannot be opened

The first portion of the stack trace is:

com.ibm.xsp.FacesExceptionEx: Unable to open database: xphwt.nsf because: Database xphwt.nsf cannot be opened

com.ibm.xsp.model.domino.DominoUtils.openDatabaseByName(DominoUtils.java:105)

com.ibm.xsp.model.domino.DominoViewDataContainer.openDatabase(DominoViewDataContainer.java:535)

com.ibm.xsp.model.domino.DominoViewDataContainer.openView(DominoViewDataContainer.java:489)

I can open the database just fine in the Notes client.

My workstation is an Apple iMac with 2Gb of RAM and a core duo processor running at 2Ghz. The OS is Vista SP1. The server is CentOS 5 (kernel 2.6.18-53.1.21.el5). Both client and server are the first 8.5 beta.

I checked, and page1 is present in the design and has proper capitalization. I searched this forum and readme_85_beta.nsf looking for notes about this application, but I didn’t see any saying it shouldn’t work under certain circumstances.

Is it not supported under a Linux server? Or am I missing something obvious (though those two options aren’t mutually exclusive).

Thanks in advance!
