在 JSP 上使用第 3 方 Java 库

Question

How can I use 3rd party libraries like Twitter4J on JSP?

Answer 1

It's a bit sick, but can you not just inline the appropriate Java in your JSP?

<%
   // This should really be in a servlet
   // Twitter4J code from their example 
   Twitter twitter = new TwitterFactory().getInstance();
   List<Status> statuses = twitter.getFriendsTimeline();
   System.out.println("Showing friends timeline.");
   for (Status status : statuses) {
       System.out.println(status.getUser().getName() + ":" +
                        status.getText());
   }
%>

Make sure that the Twitter4J jar and all its dependencies are in your WEB-INF/lib/ folder. Then, give some serious thought to not doing this in a JSP if at all possible!
