Sean Kelly created OODT-538:
-------------------------------
Summary: oodt/grid produces unclear ClassNotFound messages with
trailing spaces after product/profile class names
Key: OODT-538
URL: https://issues.apache.org/jira/browse/OODT-538
Project: OODT
Issue Type: Bug
Components: grid
Affects Versions: 0.4
Environment: PDP-11/35 running TOPS-19.5
Reporter: Sean Kelly
Fix For: 0.5
In order to avoid typing overly long class names into the OODT Web Grid
configuration panel, users commonly resort to copy & paste. However, there's a
risk of grabbing a trailing space when copying & pasting. Web Grid happily
records a long class name as "a.b.c.d.DProductHandler ", along with that
trailing space, but the user in unaware since it looks just fine in the
HTML-marked up web page.
The problem occurs when Web Grid tries to instantiate such a class. This
produces a nice Tomcat error page with a java.lang.ClassNotFoundException;
however, the user is still unaware that anything's amiss because the error page
is also rendered in HTML and hides the trailing space.
To avoid such time losses in the future, Web Grid should strip spaces from
class names that are entered into its config page. It may as well and do that
for other items on the config page as well, such as the code bases list.
