http://nagoya.apache.org/bugzilla/show_bug.cgi?id=26662 ClassCastException in GzipOutputFilter Summary: ClassCastException in GzipOutputFilter Product: Tomcat 5 Version: 5.0.18 Platform: PC OS/Version: Windows XP Status: NEW Severity: Normal Priority: Other Component: Connector:Coyote AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] When using the compression filter included with the coyote connector I get ClassCastException's when navigating our site. It is at line 165 in the GzipOutputFilter 159 public long end() 160 throws IOException { 161 if (compressionStream == null) { 162 compressionStream = new GZIPOutputStream(fakeOutputStream); 163 } 164 compressionStream.finish(); 165 return ((OutputFilter) buffer).end(); 166 } the buffer being cast into an OutputFilter is not always an OutputFilter as show in InternalOutputBuffer line 309 306 public void addActiveFilter(OutputFilter filter) { 307 308 if (lastActiveFilter == -1) { 309 filter.setBuffer(outputStreamOutputBuffer); 310 } else { 311 for (int i = 0; i <= lastActiveFilter; i++) { 312 if (activeFilters[i] == filter) 313 return; 314 } 315 filter.setBuffer(activeFilters[lastActiveFilter]); 316 } 317 318 activeFilters[++lastActiveFilter] = filter; 319 320 filter.setResponse(response); 321 322 } as you can see if lastActiveFilter = -1 then the buffer is set to outputStreamOutputBuffer which is an OutputStreamOutputBuffer which inherits from OutputBuffer not OutputFilter so the cast fails. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
