Hi,

I have BDB XML 2.2 installed on both Windows XP and SuSE Linux.
I initially developed a small application on WinXP, using Java, that uses
DBD XML. In the WinXP system I can successfully use XQuery from within my
application to query data from the DB.

When I move the Java application to SuSE, all the DB funcations work
(created DB, write/read to/from DB) EXCEPT for using XQuery. I always get a
null returned whan doing a query. There are no other errors that I can see.

I know there is data in the DB as I can do a
getContainer().getAllDocuments(conf) and dump all the data I added to the
DB.

Anyone have any ideas?

thanks

Hi Gary,

I'm not entirely sure what might be causing this. Do queries work using
the DB XML shell on SUSE? Did you create your container on Windows, and
copy it accross to Suse? If so, does it work if you create the
container afresh on Suse?

Hi John,

I seem to have run into more problems since I orginally posted this.

First off, the only thing I moved from my windows environment to SuSE
was the Java code. Databases/containers were created separately on each
platform.

1. XQuery works well on Windows platform, but on SuSE. XQuery always
returns NULL.

2. I use transactions to add my documents to the database, each add is
with a document name. When I attempt to delete the document, again using
the document name, the deleteDocument() call hangs. This happens on both
Windows and SuSE. Under Windows, I've even tried delete with an object,
after performing a query, but delete always hangs.

3. Currently the only way I can retrieve data on SuSE is to do
getAllDocuments() and then parsing through the documents.

I've double checked my program against the sample code in GettingStarted
and in the BerkeleyDBXML-JAVA-GSG.pdf guide. It looks like I'm doing
everything right. I would think if I can add a document, I should be
able to delete it.

I will try the DB XML shell on SuSE either tomorrow or the next day.
