Have you considered using CDK 1.2 or perhaps even the CDK 1.3
development version?

Also, what is the code you use to run CDK functionality? That is, what
does the relevant source code of packageWebCdk.java look like where
you call the 3D model builder?

A HOSE code is a line notation for an atomic environment. The CDK 1.0
code you are using, uses it for looking up the proper 3D environment
for that atom. But, it is unable to find it in the database... I think
this is caused by the missing negative charge on the oxygen, but that
is just a guess.

More information on the HOSE code generation is found in this JavaDoc:

http://pele.farmbio.uu.se/nightly-1.2.x/cdk-javadoc-1.2.5.git/org/openscience/cdk/tools/HOSECodeGenerator.html

Anyway, I strongly suggest to move to CDK 1.2. CDK 1.0 is outdated,
has many bugs that are fixed in CDK 1.2, and the problem you encounter
may just be one of those.
