>          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
>  Attachments: ContentFilter.diff
> 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: 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.
