CotentServer can not set attribute "org.apache.jetspeed.content.filtered"
because of FileNotFoundException
----------------------------------------------------------------------------------------------------------
Key: JS2-406
URL: http://issues.apache.org/jira/browse/JS2-406
Project: Jetspeed 2
Type: Bug
Components: ContentServer
Versions: 2.0-M4
Environment: JDK 1.4.2_10, WinXP SP2
Reporter: James Liao
Priority: Critical
There is a bug about contentfilter.
1. Login j2 as a portal user(admin).
2. Click the CSS Demo page.
3. Click the CSS portlet maximize windown icon.(a
java.lang.IllegalStateException had been logged in jetspeed.log)
4. Click the default-page.psml.
5. The following is the displayed in browser.
javax.servlet.ServletException: Fatal error encountered while processing portal
request: org.apache.jetspeed.pipeline.PipelineException:
org.apache.jetspeed.pipeline.PipelineException:
org.apache.jetspeed.pipeline.PipelineException
: org.apache.jetspeed.pipeline.PipelineException:
java.lang.IllegalStateException: You cannot invoke getRenderedContent() until
the content has been set.
org.apache.jetspeed.engine.JetspeedServlet.doGet(JetspeedServlet.java
:235)
javax.servlet.http.HttpServlet.service(HttpServlet.java:689)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
6. The current browser can not view j2 anymore.
The cause of this is a FileNotFoundException throw in ContentFilter. The
following is the detail:
1. The css-demo.psml use blue-gradient as its portlet-decorator. The following
lines are from blue-gradient's css file
.blue-gradient .portlet-msg-status {
background: url(content/tigris/images/icon_status_sml.gif);
background-repeat: no-repeat;
padding-left: 20px;
min-height: 15px;
}
The above gif file could never be found according to the current content list
paths.
2. A FileNotFoundException will be thrown out when browser try to request for
these gif files at the following code:
SimpleContentLocator contentLocator = new SimpleContentLocator(this.contentDir,
urlHints, useCache, httpRequest .getContextPath(),
requestURI, getContentSearchPathes(httpRequest));
so the following code could never be called:
httpRequest.setAttribute("org.apache.jetspeed.content.filtered", "true");
3. This will lead to when browser request a *.gif file, the jetspeed pipeline
get called and then a java.lang.IllegalStateException got fired.
A quick fix is moved the line
"httpRequest.setAttribute("org.apache.jetspeed.content.filtered", "true");"
before creating SimpleContentLocator.
I also notice that JS2-398 might fix this issue gracefully too, then just
ignore me.
