public class TeaLog
extends Log

The TeaLog class extends a regular log. It simplifies stack traces for the TeaServlet so it is easier for template authors to understand. It strips off irrelevant stack trace elements in the stack trace leaving only the template and application elements. These are the only elements that are relevant unless there is a bug in the Tea hosting environment - which never happens! ;-) This TeaLog is designed to be used in hosting environments such as the TeaServlet and StaticTea. These hosts use templates as the controller so any stack traces elements before the templates are irrelevant. Authors of systems that don't use templates as the controller will probably not want to use the log as their stack traces will not return to them enough information. Some examples are listed below. The Trove Log class displays exceptions as: java.lang.NullPointerException at org.teatrove.teaservlet.template.Test1NullPointer.execute(Test1NullPointer.tea:2) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.teatrove.tea.runtime.TemplateLoader$TemplateImpl.execute(TemplateLoader.java:270) at org.teatrove.tea.engine.TemplateSourceImpl$TemplateImpl.execute(TemplateSourceImpl.java:838) at org.teatrove.teaservlet.TeaServlet.processTemplate(TeaServlet.java:594) at org.teatrove.teaservlet.TeaServlet.doGet(TeaServlet.java:259) at org.teatrove.barista.servlet.TQTeaServlet.doGet(TQTeaServlet.java:117) at javax.servlet.http.HttpServlet.service(HttpServlet.java:740) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.teatrove.barista.http.HttpServletDispatcher$ServletFilterChainTransaction.doFilter(HttpServletDispatcher.java:1436) at org.teatrove.barista.http.HttpServletDispatcher$ServletFilterChainTransaction.service(HttpServletDispatcher.java:1409) at org.teatrove.trove.util.tq.TransactionQueue$Worker.run(TransactionQueue.java:671) at org.teatrove.trove.util.ThreadPool$PooledThread.run(ThreadPool.java:676) The TeaLog class displays exceptions as: java.lang.NullPointerException at line 2 of template Test1NullPointer.tea
