Servlet filters with Struts
Hi,
Iam using TimerFilter in my application which gives the response time taken for executing the each Action class. Does this will affect the performance of the application on production environment. Is there any known performance or stability issues with Servlet filters with Struts?
Thanks in advance,

Storing encrypted passwords for database connection
Posted by Ramil Mirhasanov <ra...@dolunay.com.tr>.
In my project I want to encrypt database users' passwords.
They can be stored in .properties file or deployment descriptor, maybe.
Are there any suggestions how to implement this task?
Are there some mechanisms in struts framework that support the encrypted
storage of passwords?
Thank you in advance!
Ramil

The most important consideration when dealing with performance issues is
to understand where the bottlenecks are that are affecting you. For
many web applications it tends to be database access, but there's no way
to generalize, because every application is different.
One approach to investigating this, for example, would be to copy the
database access logic of your webapp into a stand-alone test program,
and run some timing tests there, with no web container or user interface
framework involved.

Precompiling JSPs only helps make the very first request to that page
run faster ... it has zero impact on ongoing performance.

PS: The servlet container's implementation of a filter will typically
have about the same performance impact
as a RequestDispatcher.forward() call, which isn't much -- basically
it's a lookup and a method call. Obviously, anything your Filter
actually does will affect the timing, but adding simple stuff like "how
long did this request take to process" and then logging that will have
little or no visible impact unless your webapp is overloaded with users
or something like that.

Hi,
I have the same issue.Seems struts is running pretty slow (or porbably its becuase of back end database connections to mysQL using Hberntae).Any waqys I can improve the perfrmance. I am using Weblogic 7.0
Thanks so much as this will highly help in running my jsp's faster ( I did try including jsp pre-compilation into jasper).
Regards,
Sam.

console it should be OK -- the other thing that is nice about filters is
that they can easily be turned off via the filter mapping.

Well of course it will affect performance because the container is doing
stuff it would not be doing otherwise -- the question is more like "will
the negative performance impact be significant?" I would say if you
calculating the elapsed time it should not be. It depends on what your
filter is doing with the data -- it is simply logging it out to the
console it should be OK -- the other thing that is nice about filters is
that they can easily be turned off via the filter mapping.
