We are trying to extract data from a pdf but for some pdf's i am getting this error but when we change the strategy to "SimpleTextStrategy" it is extracting the data but in a non sequential manner. So do i need to add libraries for itextpdf?

I'm sorry but I fear you posted to the wrong project. I do not know what the above problem has to do with the Sweble Wikitext parser...
