I will try tonight. @masijade Thank you so much! Re: MailUserBean Errors 14 Years Ago by sillyboy there is no such thing as javax.servlet.http.HttpSession.getAttribute() Re: MailUserBean Errors 14 Years Ago by kvprajapati I think that you are using different version of MailUserBean.

This is equivalent to classes like Integer, Boolean, and Double (among others). If you're using 1.5 (Tiger, 5.0) that wrapping will be taken care of for you. If you use the correct Tree from the collections API your sorting will be done for you and all you'll need … Re: Someone help me hate trees less 19 Years Ago by kharri5 thanks for the hint on Character class...niiice....but the Tree i have to construct from scratch. can't use predifined stuff for it. I have no idea how to set up the tree class, and what methods it should have...the API has confused me more I think. Re: Someone help me hate trees less 19 Years Ago by jwenting Check out any decent book on data structures, all should have information on defining trees and iterating over them. You may also look at the sourcecode for java.util.TreeMap or java.util.TreeSet and take inspiration from there. Re: Summing Issue from Array 16 Years Ago by iamthwee What are you trying to do your code makes little sense?

I moved the count line to run after the totalValue line. Logic being, the count was moving forward before I was ready for it to. Thought I had it because now I can run the loop again. When I enter STOP to leave the loop, and hopefully see my total value I get a whole string of errors. Again, it …
