----------------------------------
Summary: Resin 4 Compatability
Key: JSPWIKI-759
URL: https://issues.apache.org/jira/browse/JSPWIKI-759
Project: JSPWiki
Issue Type: Improvement
Components: Servlet Container/Java compatibility
Affects Versions: 2.9
Environment: OSX 10.8.2, Oracle Java JDK 1.7.0_09
Reporter: Paul Cowan
I am an engineer for Caucho on the Resin Application Server, and was testing
JSPWiki on Resin version 4.0.34. I would like to submit 2 fixes to enable
JSPWiki to run better on Resin 4:
#1. JSPWiki is calling getOutputStream after getWriter(). The servlet spec
dictates we throw IllegalStateException for this situation. I see JSPWiki
already has handling in UtilJ2eeCompat to use an OutputStream rather than a
Writer depending on the container. The Resin check should have "useStream =
true".
#2. As a consequence of #1, JSPWiki serves empty content. This is due to
buffering inside the PrintWriter used by
WikiJSPFilter.ByteArrayResponseWrapper. The PrintWriter is never flushed when
toString() is called on ByteArrayResponseWrapper. (This may not be a Resin
specific issue.)
I will attempt to attach a patch file to this bug report containing my fix to
WikiJSPFilter.java.
