Hi Khalida,
In a previous message, you mentioned that the speed of your Internet connection and the storage capacity of your computer were giving you trouble.
I know this is not directly on-topic on this list, but since you seem to have tried and exhausted many options already, perhaps you would consider running your code on a cloud-based computer, such as a server from Amazon EC2? Doing so would allow you to get around both connection and storage issues, and perhaps allow you to run your Java code successfully, or perhaps to run JWPL successfully.
Using EC2 is not particularly simple, but it is technically straightforward and not too hard, either. The Getting Started Guide is here:
http://docs.amazonwebservices.com/AWSEC2/latest/GettingStartedGuide/
The pricing is quite inexpensive if you limit the number of hours you use the servers. There is even a free tier for new users http://aws.amazon.com/free/, although with your needs you might choose to pay (again, a small amount) for server(s) with larger capacity.
I can offer a small bit of EC2 guidance off-list if you need other pointers in getting started.
Pete

I need an Html dump of Wikipedia because I have written a java code which extract text from an html content and I would like to apply it on this dump. In fact I need to extract the first sentence of a list of articles (<200) and I don' know how to do it on other dumps. If you have any idea of other solutions, I will be pleased if you share them with me.
