Dear users,
We are using myfaces-1.2.9 with apache-tomcat-6.0.35. We have a JSF
page which works fine most of the time.
However, recently all of a sudden, the JSF page became unavailable. On
checking the logs following lines are observed.
Any idea what is the likely cause ? Please let us know. We cannot
share the JSF code, but please note that we have one JSP scriptlet
"<%.... %>" within the JSF page for accessing backend database and
pre-processing. Is this likely cause for the problem ? Please advice.
regards
-yogeen
