jak uruchamiam aplikacje z bata z parametrem JAVA_CLIENT
wyrzuca exception kiedy dochodzi do jednej z tych funcji

resultset=li.getBookByAuthor(book_author.getText());
resultset=li.getBookByName(book_title.getText());
resultset=li.getBookByISBN(book_isbn.getText());
resultset=li.getAllBooks();

Prosze o pomoc
Dziekuje
