Suppressing stack dump in executeMethod()

I most likely should know how to find the answer to this question,
but...

I am doing SSL and when I use an incorrect password for the keystore it
looks like somewhere in HttpClient.executeMethod() the stack dump is
being printed..  In my application I am catching everything I should be,
and I don't want to user to see this information.  Is there a way for me
to tell HttpClient to suppress this output. I want to handle this
exception in my application. Thanks.

Christopher,

What makes you think that HttpClient dumps the stack? What I read from
the stacks tells me that is was not HttpClient#executeMethod

org.apache.commons.httpclient.HttpClient.executeMethod(HttpClient.java:529)
>         at xxx.xxxxxxxx.xxxxxx.xxxxxx.run(Unknown Source)
> 

Then, HttpClient NEVER dumps exception stack using
Throwable#printStackTrace(). NEVER EVER. HttpClient always uses
commons-logging to log its events. 

In order to disable all output generated by HttpClient you may want to
set HttpClient's logging verbosity to FATAL or disable logging output
altogether by using NoLog as a logger implementation. 

Feel free to examine HttpClient's source code to double-check

Oleg
