Please help with weight, no matter what i set i am getting same numbers

I am trying to integrate Sphinx in my Java back-end, using the MySQL Connector/J to connect to it. I’ve basically followed the tutorial from the Sphinx Wiki (http://sphinxsearch.com/wiki/doku.php?id=sphinx_jdbc ) but get the following error: JDBC Connection Failure: CLIENT_PLUGIN_AUTH is required on the line:

I have big table with materials with description like ‘Sheet 10×200…’ and so on.
I want to index dimensions as different keywords, so when I type ‘sheet 10’ I can see all sheets with other dimensions.
