Subject: Re: java.lang.thread exception while using Xalan 2.0 in WLS 6.0
From: "Chuck H. Zhao" <[EMAIL PROTECTED]>
I am having the exact same problem you are having. If we analyze the stack
trace:

at
org.apache.xalan.transformer.TransformerImpl.run(TransformerImpl.java:2894)
at java.lang.Thread.run(Thread.java:484)
What happened is: to support incremental output, Xalan-Java performs the
transformation in a second thread while building the source tree in the main
thread. So Transformer.transform() creates a new thread to run the
transformer.run() method, which will write to weblogic's internal
ServletOutputStreamImpl, and in the end calls flush() on it.
ServletOutputStreamImpl determines that the headers haven't been written
yet, and the headers need to be written before any servlet output, so it
calls ServletResponseImpl.writeHeaders(), which eventually calls
ResponseHeaders.setDateHeader(). The last method assumes the thread is
weblogic's internal ExecuteThread and tries to cast the thread as such,
maybe to get the date from it. But the thread is a plain java.lang.Thread
created by xalan, thus we get the java.lang.ClassCastException:
java.lang.Thread
This suggests a second workaround: call ServletResponse.flushBuffer()
before any xalan stuff, which will force the headers to be written in
weblogic's ExecuteThread. The shortcoming of this is that this will cause
the response to be commited, and if the xalan stuff throws exception you can
not forward to another page.
Another thing is that xalan should not directly call flush() on
ServletOutputStreamImpl at all. I will report it to xalan and see if they
consider that a bug. If they fix that then we have a third workaround: set
the buffer size of ServletResponse big enough to accomodate everything
including the xslt outputs, so the ServletOutput does not need to be flushed
during xalan code.
I do not consider this problem a weblogic bug, since the servlet container
has to right to expect any thread inside it to be its own. Serlvet 2.2 spec
says:
1.2 What is a Servlet Container?
...
A Servlet Container may place security restrictions on the environment that
a servlet executes in. In
a Java 2 Platform Standard Edition 1.2 (J2SE) or Java 2 Platform Enterprise
Edition 1.2 (J2EE)
environment, these restrictions should be placed using the permission
architecture defined by Java 2
Platform. For example, high end application servers may limit certain
action, such as the creation of
a Thread object, to insure that other components of the container are not
negatively impacted.
Weblogic should explicitly warn the developers that creating threads inside
the servlet container may have adverse effects, the same kind of problem we
are having. (or maybe they already did somewhere in their documentation?)
On the xalan side, I would suggest them to either give the option to switch
the two threads, or to give the option to buffer the output and write it out
in the main thread, which is exactly what you did in your first workaround.
Any comments or thoughts on the subject are welcome.
