Re: [Exist-open] Help: xmlrpc encoding problem when upoadingxmlfile with ISO-8859-1 encoding

[dr. J. A. <info@CompChemCons.com>]

I found a solution, but I do not understand why it works.

The first line of the file that is loaded contains:
<?xml version="1.0" encoding="ISO-8859-1">
When I load the contents of the file into a Java String, and then submit 
that to the xml-rpc, the german characters get skrewed up.
If I do however remove the <?xml ...> statement from the string, the german 
characters are OK when I look at the document in the database.

Might it be that the xml-rpc does not like "<?xml version="1.0" 
encoding="ISO-8859-1">" as content ?

With best regards

Jozef Aerts
