RE: JNI error under tomcat: java.lang.UnsatisfiedLinkError
do you get this error upon first deployment or re-deploy?
do you restart tomcat after you redeploy your jni app?

Hi Dennis.
So do you see the Load library successful message?
Also, if I remember correctly, the code in eval.java is not a safe way to
load a native library. It's a very good idea to place the System.loadLibrary
in a static { } block, instead of in a method. The way your class is
written, it's possible for the run method to be executed more than once, in
which case loadLibrary will be called more than once (and so will the native
initModels). Not sure what the effects are and if it's related to your
problem but it's a good idea to avoid trouble by fixing it.

Hi,
I have a java class (eval.java) that invokes a native method in an so file
(libmodel.so, using SWIG 1.3.29 to generate JNI code/wrapper and compiled
the library). I can use System.loadLibrary() to load the libmodel.so
without
any error (-Djava.library.path=/usr/lib), and the native method initModel()
works fine as a standalone application.
However, when I deploy it as a web service (tomcat 6.0.26 + axis2 1.5.1 +
eclipse jee helios) to call the native method, I got the following error
(the first line means the .so was successfully loaded):

can you extend org.apache.catalina.connector.Response adding the HttpResponse

and call that before valve.invoke()
also depending on what you are putting in your cookie and if the users are
logging on or not (you could also use ipaddress but that is flaky is they are

Subject: using Servlet Filter to rewrite domain of JSESSIONID cookie?
I'd like to make session cookie domain-wide, and ignore subdomains - in
Tomcat 6. So for app reachable via my.site.com and www.site.com, I'd like to
have session cookie's domain be .site.com. I thought of doing so using a
ServletResponseWrapper and a servlet Filter:
@Override
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException,
ServletException
{
if (!(response instanceof
SessionCookieDomainSettingServletResponseWrapper))
{
response = new
SessionCookieDomainSettingServletResponseWrapper((HttpServletResponse)
response);
}
chain.doFilter(request, response);
}
and in wrapper:
@Override
public void addCookie(Cookie cookie)
{
if (cookie != null SESSION_COOKIE_NAME.equals(cookie.getName()))
{
// update domain name to just the domain
stripSubDomain(cookie);
}
super.addCookie(cookie);
}
However, JSESSIONID continues to be set to FQ host name (my.site.com).
Is it because Tomcat internals do not use HttpServletResponse.addCookie() to
set JSESSIONID or is that cookie set before filter chain gets executed?
If so, sounds like Filter is (sadly) not applicable for this case, and I
have to create a custom Valve? Any tips on how to
wrap org.apache.catalina.connector.Response - valve.invoke() does not take
HttpServletResponse...
