Hi ,
I have a serious problem with Resin 2.1.6 + Linux (RH 7.3) + JSTL with Jakarta Taglibs
1.0.2 implementation.
Sometimes , the server load too high (or some strange reason that I cannot make sure),
and one strange JSP error will occure :
[2002/12/25 19:35:37] _jsp._SomePage__jsp: init
[2002/12/25 19:36:42] null
javax.servlet.jsp.JspException

The error cannot be automatically recovered in time !!! Even after I add <jsp
recompile-on-error='true'/> in my web.xml , it will still throw error and recompile
the page and throw this JspException again and again....All I can do is manually
restart the webapp......
I don't know what reason cause this JspException , I checked the code very carefully
and I am sure there is no null object/reference in my page and beans. It seems the
error occurrs when the server load goes very high . But not every high load time will
cause the JspException . It maybe the Jakarta JSTL implementation problem.
Anyway , I cannot stay beside the website terminal and watch the load forever. I
wonder is it possible to make resin automatically restart the webapp upon the
JspException ?
Strange error , I thought my server is good enough (P4-2G , 1GB RAM) , but sometimes
Resin still eats up all my memory and throws OutOfMemory Exception.......
(Sorry , I also CC to Jakarta taglibs maillist , because I think this problem seems
related to Jakarta taglibs implementation.....)
