Hello Mattias
If you are wanting to log from a servlet, then this could help...
The GenericServlet class (a super class of HttpServlet - and therefore one
that you will almost certainly be importing already) contains two log()
methods.
One for just a String message eg:
log("we are in init()");
And one for a String with a Throwable parameter - to use as part of error
handling eg:
Catch(Exception e){
log("it broke because: ",e);
}
And those messages should end up in yr log.txt as specified in yr web.xml
Try and see if you've got the api docs installed - this is where mine are:
http://127.0.0.1:8080/tomcat-docs/servletapi/javax/servlet/GenericServlet.ht
ml
Hope that helps
Steve
