Hello,
We've been running Tomcat 6.0.36 without issues for many months. Our
pages have many components and are constructed using
getRequestDispacher("...").include(request, response) to pull the
components in.
For the past few weeks, we've had a few instances where, in constructing
a page, the parameters in the query string passed to
getRequestDispatcher(), are not being passed through to the components
included.
For example, if a browser submits the request /main.jsp?id=foo, then
from that page, we include /product.jsp?id=bar, the product.jsp page
should see the following parameters:
id = [ bar, foo ]
This happens almost all the time, but sporadically, we're getting just:
id = [ foo ] instead.
If the entry page was /main.jsp?cat=foobar, for example, then on
including /product.jsp?id=bar, we should get:
id = [ bar ], cat = [ foobar ]
But instead, we sometimes get just:
cat = [ foobar ]
Here is an extract from our logs. The first is just before the call the
getRequestDispatcher().include(), and shows the URI.
19 Jun 2014 2:58:04 PM org.apache.catalina.core.ApplicationContext log
INFO: Trace @ 2014-06-19 14:58:04.808 [system: TP-Processor7]
/full/include/view/generic/smallfeature.jsp?id=25951215082928&cached=true
web.Session$Site.include(Session.java:58)
And then the smallfeature.jsp logs the contents of the parameterMap
directly thereafter:
19 Jun 2014 2:58:04 PM org.apache.catalina.core.ApplicationContext log
INFO: Trace @ 2014-06-19 14:58:04.81
[993BE7ADFD65B94F2A62E85B64B3B8A2/null: TP-Processor7]
Parameters: cat = lcu; page = browse;
web.tags.Log.doStartTag(Log.java:48)
You can see the id and cached parameters are missing, and the parameters
that are available are actually those from the main page. Has anyone
experienced this before, or know what may cause it?
Thanks,
Michael.
