Re: [jira] Commented: (GERONIMO-1674) Daytrader gets NullPointerException attempting to log in a user

J. Stan Cox Wed, 28 Jun 2006 09:47:36 -0700


Good thoughts Joe.   I think both need to be fixed.

1) The default values for users and quotes should be increased to arealistic value for performance work. I agree with Chris that quotesshould be default to 1000 and I think users should default to 500.

2) Setting these to a much lower value is great for debugging especiallywhen there is a problem with populating the database. So the codeshould be fixed to support the case when less then 200 quotes arepopulated. I don't think it would be a complicated fix. I'll look atthe code and get back.

Thanks for your response Chris.
So are you saying that even the defaults for Daytrader areinsufficient? What's confusing is that it always returns a "loginerror" even though it appears that login succeeds and this is reallyrelated 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 of50 users and 100 max quotes I still get the error. You are correctthat making the max quotes 1000 resolves the problem.
So, I guess the next question is "what needs to change?". It seemsthat we should not ship the sample with default values that don't workwell with the application. We also should not allow the user to setvalues that can cause a failure.
However, I'm not clear if the correct fix should be changing thedefaults (and validating settings to ensure they are not "too small")or changing the display code to deal with the range of values that canbe set. What is the recommendation of the Daytrader experts?

Joe...
I've worked on Trade for quite some time and am slowly starting todig into DayTrader. Anyway, just wanted to respond to your questionsince I think I know what the problem is.
In order for the MarketSummary to be display, at least 200 quotesneed to be populated in the database. If you look at the queries theMarketSummary uses (either the EJBQL or SQL in TradeDirect.java) youwill see something like this...
<ejb-ql>SELECT OBJECT(q) FROM Quote q WHERE q.symbol LIKE 's:1__'ORDER BY q.change DESC</ejb-ql>
This indicates that the MarketSummary needs quotes between 100 and199. If we are only populating 10 quotes by default, this query willreturn 0 results and I imagine the MarketSummary will throw anexception (as indicated by the stack traces).
To get you up and running, I would re-populate your database with atleast 200 quotes. The default for Trade was actually 1000.
I also suggest that the default be changed from 10 to something morerealistic for performance testing ( i.e. 1000 or even higher).
Hope this helps...

    ------------------------------------

    I still get this error.  I get it with tomcat as well as jetty.   I
    think I may very well be doing something wrong.  Here is my scenario
    after successfully deploying daytrader.

    1)  select configuration->configure Daytrader runtime paramenters
    ...  and change the max users and max quotes to 10 each.   Note, I'm
    not really running daytrader for performance stats ... I was just
    using it to verify geronimo functions after making some substantial
changes as a way to verify that I hadn't broken things tooradically.
    2)  from confirguration select (Re)-populate Daytrader
    Database.  This appears to be successful.
    3)  Next, from under Configuration utilities I select "Test
    DayTrader Scenario" and I get this attached exception.   It does
    seem strange that if I do this a number of time eventually things
    seem to start working.

    Here is another stack trace (unfortunately from jetty again but I do
    get it with tomcat as well) from a recent attempt on 1.1.
