Hi guys I'm very desperate I explain what happens is that I'm doing my project for titling in the I have to do a web processing service using a tool called freeling, I managed to use it and I did a java class in the I use the libraries of that tool and it correctly processes the text in the class and shows me the results correctly in the console. The problem is that when I did my soap web service, my client, my servlet and I try to call from the web service methods of my class java does not appear anything in my client only appears in white. I did some tests creating simple methods that only returned a string to the client and if they work but when I get to the part of creating an object the freeling tool classes no longer work or the methods of returning a string only remains blank client, and I do not know where the error is since the client does not show me any exception or anything I hope someone can help me to know what is happening and I was looking for a solution like crazy I have not slept for 3 days and I have not made any progress or if someone knows how I can show the exceptions that occur when calling my methods in the web service to know where my error is, I attach a photo of my structure. Since already a million thanks for your support.
