Exception without cause
Hi!
I have the seam application that successfully works on one server. I just copied it to another server. It deploys fine with no errors. But when I try to invoke it I have the debug page with no exception cause. I just have this exception:
Exception during request processing: Caused by javax.servlet.ServletException with message: "Servlet execution threw an exception"

I was trying to catch the exception with my custom Filter:
public class BaseEncodeFilter implements
javax.servlet.Filter {
private javax.servlet.FilterConfig myFilterConfig;
public BaseEncodeFilter() {
}
public void doFilter(
javax.servlet.ServletRequest servletRequest,
javax.servlet.ServletResponse servletResponse,
javax.servlet.FilterChain filterChain)
throws java.io.IOException,
javax.servlet.ServletException {
System.out.println(" doFilter " );
try{
System.out.println(" before try");
filterChain.doFilter(servletRequest,
servletResponse);
System.out.println(" after try");
}catch(Throwable e) {
e.printStackTrace();
System.out.println("Stack trace:");
System.out.println(e.getStackTrace());
System.out.println("Cause:");
System.out.println(e.getCause());
}
}
public javax.servlet.FilterConfig getFilterConfig() {
System.out.println("getFilterConfig" );
return myFilterConfig;
}
public void setFilterConfig(
javax.servlet.FilterConfig filterConfig) {
System.out.println("setFilterConfig" );
myFilterConfig = filterConfig;
}
public void init (javax.servlet.FilterConfig filterConfig){
System.out.println("init filterConfig" );
myFilterConfig = filterConfig;
}
public void destroy(){
myFilterConfig = null;
}
}
in web.xml:
<filter>
<filter-name>Errors Filter</filter-name>
<filter-class>logging.BaseEncodeFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>Errors Filter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
But it does not catch any errors, it "says" than everything is ok. Please help!
Best regards,
Kristina
