Sorry for the delay with the reply. It seems my first suggestion regarding reusing of class instances was wrong.
In theory the following tags
<pd4ml:parameters>
<pd4ml:parameter key="pd4ml.cache.enable" value="false"/></pd4ml:parameters>
nested to
<pd4ml:transform> should help. (Identical System.setProperty("pd4ml.cache.enable","false") may fail due to server's security restriction)
I would also recommend to add
debug="true" attribute to
<pd4ml:transform>In the case if the caching is successfully disabled it should print to server's log
cache disabled. (re-)reading <URL>Please check if it works for you and outputs the debug message.
