I am trying to enable a simple app built using Struts2.0 framework for
OpenId. The application is deployed on Apache Tomcat 6.0. I get a
javax.servlet.ServletException at new ConsumerManager() call. Below is
the trace and other relevant information.
org.apache.catalina.core.StandardWrapperValve invoke

There's nothing from org.openid4java.* in the stacktrace. Was it omitted
from your message, or else how do you know/link this stack with the
instantiation of the ConsumerManager?

Well this is the complete stack trace and nothing has been omitted. I initiated remote server debugging the control goes to line (it hits the following breakpoint)
consumer = new ConsumerManager();
From this line onwards it throws a ServletException. I also downloaded the code from server repository and set a break point at the very first line in the constructor of ConsumerManager.
_httpClient = HttpClientFactory.getInstance(
_maxRedirects, Boolean.FALSE, _socketTimeout, _connectTimeout,
CookiePolicy.IGNORE_COOKIES);
The runtime flow doesnt hit that breakpoint and throws the servletException even before this.
I guess I am doing something wrong in Struts configuration. I came across one of the posts at OpenId4java group where Ratapouak talked about having used this library inside a webapp using Struts fwk. But he also mentioned having used a singleton per classloader manager that handles ConsumerManager. I dont know what he did in there.

Then it's probably a deployment / configuration issue. Maybe check how
endorsed libraries are handled in tomcat6, though it's not obviously
related.

Hello Ankush,
I saw your message yesterday so sorry for the late response. I join
Jonnhy on that, how can you be sure this is an openid4java error ?
I didn't do anything particular in my webapp, just made a singleton
adapter to encapsulate the ConsumerManager class. Then in my code, I
call Adapter.getInstance().method() that does some stuff and delegates
the business to the underlying ConsumerManager object instance.
I'm using it in Tomcat 5.5 and struts 1.2.9 but I don't see why this
may fail with higher versions.
Have you embedded commons-httpclient in your war ?
