Re: [jira] Commented: (GERONIMO-1674) Daytrader gets NullPointerException attempting to log in a user
Hi Joe, My name is Slava and I work with Trade on a daily basis. Recently, I started to look into Daytrader because I would like to start contributing to the Daytrader development. When I first attempted to run Daytrader1.1 on Geronimo1.1, I ran into the same NPE problem. I agree with you that the Daytrader code needs to be fixed. Actually, Ive already looked into the code and I think that the problem is not in the marketSummary.jsp itself but rather in the TradeBean that builds the Market Summary object. I am going to try a couple of fixes. I will keep you posted on my progress. Slava --- Matt Hogstrom [EMAIL PROTECTED] wrote: J.

Re: [jira] Commented: (GERONIMO-1674) Daytrader gets NullPointerException attempting to log in a user
Thanks for your response Chris. So are you saying that even the defaults for Daytrader are insufficient? What's confusing is that it always returns a login error even though it appears that login succeeds and this is really related to the initial display(s). I get the same error if I select Trade Portfolios and then log in. I also noticed that even if I return the settings to the defaults of 50 users and 100 max quotes I still get the error. You are correct that making the max quotes 1000 resolves the problem. So, I guess the next question is what needs to change?. It seems that we should not ship the sample with default values that don't work well with the application. We also should not allow the user to set values that can cause a failure. However, I'm not clear if the correct fix should be changing the defaults (and validating settings to ensure they are not too small) or changing the display code to deal with the range of values that can be set. What is the recommendation of the Daytrader experts? Joe Christopher Blythe wrote: Joe... I've worked on Trade for quite some time and am slowly starting to dig into DayTrader.

Chris, DayTrader has two uses to us. One is clearly as a performance benchmark, but DayTrader is also a very useful sample (test) application that touches most parts of the J2EE specification. We dropped the default population sizes because Derby is so slow at inserts it would take several minutes to repopulate.

Re: [jira] Commented: (GERONIMO-1674) Daytrader gets NullPointerException attempting to log in a user
So, at the very least the code needs to be fixed to support a smaller quote population. Perhaps we could also provide 2 basic settings on the configuration page: 1) Default, out of box sample application (low number of users quotes) 2) Performance test, larger default values (e.g. 1000 quotes, 500 users) It would be good to settle on specific values for performance testing so results will be comparable.

[jira] Commented: (GERONIMO-1674) Daytrader gets NullPointerException attempting to log in a user
[ http://issues.apache.org/jira/browse/GERONIMO-1674?page=comments#action_12414459 ] Bryan Noll commented on GERONIMO-1674: -- Can you please give some specifics on what exact action you are taking in the gui to get this to occur? Are you running a scenario? I ask because I've sucessfully run scenarios, which logs a user in. I did it with a Tomcat assembly on a recent 1.1 SNAPSHOT, and I see by your stacktrace that you were doing it with Jetty. If you can tell me exactly what you're doing, I'll try that in the Tomcat assembly to see if I have the same issue.

I believe some of this behavior has changed. So, it's quite possible that the problem no longer exists. I don't know if Joe's problem is the same as the one I saw...
