RE: Insert PNG File from Servlet no go

Only other thought is that the url is not being processed correctly...
I mean "http://www.obsidian-studios.com/servlet/Picture" is not the full =
url surely (or is picture the servlet, or did you replace the picture =
name with that)?  If there is a space in the url, try encoding it with =
%20.

Unfortunately at the moment I only use the offline jgenerator mode, so I =
probably don't get the same errors, but I know when I tried =
"http://127.0.0.1/png pics/lgc202.png" it gave an error, but when I =
tried "http://127.0.0.1/png%20pics/lgc202.png" it worked just fine.

Because of the above limitation, it may take me awhile to track down =
your error, but by all means send it along and I will have a look at it.

All my png images start with those 4 bytes. Both before insertion into
the db, while in the db, and after extraction from the db.

I have verified before, while, and after. Any more suggestions?

I can send you the url and params to see the images yourself?

I can also email the code behind the servlet, but will post neither to
the group. Only directly to your or Dmitry.
