Lukasz Lenart updated WW-4371:
------------------------------
Description:
I looked for help on the struts mail list but was unable to find a solution. I
am experienced with software, but a relative novice to web programming and
totally new to Struts. I'm trying to learn struts 2 by running the tutorial
examples.
I was able to run the 'basic_struts' example with no problem.
When I ran the 'hello_world' example, it ran successfully once, but any follow
up runs have created a stack trace. I suspect the stacktrace is caused because
my environment is somehow non-conforming. However,
I doubt that a stacktrace is the error response that you would want Struts 2 to
provide.
If you have questions, please send email to:

Regards,
Jim
The stacktrace is long, but here it is:

> Project: Struts 2
> Issue Type: Bug
> Components: Example Applications
> Affects Versions: 2.3.16.3
> Environment: Crunchbang Linux - Linux furillo 2.6.32-5-686 #1 SMP Wed
> Apr 9 19:23:16 UTC 2014 i686 GNU/Linux
> java 1.7.0_51

> hardware: Toshiba Satellite 305D-S5974
> Reporter: Jim Anderson
> Priority: Minor
>
> I looked for help on the struts mail list but was unable to find a solution.
> I am experienced with software, but a relative novice to web programming and
> totally new to Struts. I'm trying to learn struts 2 by running the tutorial
> examples.
> I was able to run the 'basic_struts' example with no problem.
> When I ran the 'hello_world' example, it ran successfully once, but any
> follow up runs have created a stack trace. I suspect the stacktrace is caused
> because my environment is somehow non-conforming. However,
> I doubt that a stacktrace is the error response that you would want Struts 2
> to provide.
> If you have questions, please send email to:
