ajax4jsf Filter should ignore HTTP 304 and other responses <200 or >299 ----------------------------------------------------------------------- Key: RF-8277 URL: https://jira.jboss.org/jira/browse/RF-8277 Project: RichFaces Issue Type: Bug Security Level: Public(Everyone can see) Components: component-a4j-core Affects Versions: 3.3.3.BETA1 Reporter: Mark Struberg Fix For: Future It seems the Filter currently tries to reformat the response in any case. But if you e.g. get a HTTP 304 response, this doesn't even have a content body (onyl headers) and wrinting to the response causes an Exception: {noformat} java.lang.IllegalStateException: NO CONTENT at org.mortbay.jetty.HttpGenerator.addContent(HttpGenerator.java:106) at org.mortbay.jetty.AbstractGenerator$Output.write(AbstractGenerator.java:644) at org.mortbay.jetty.AbstractGenerator$Output.write(AbstractGenerator.java:579) at java.io.ByteArrayOutputStream.writeTo(ByteArrayOutputStream.java:109) at org.mortbay.jetty.AbstractGenerator$OutputWriter.write(AbstractGenerator.java:901) at org.mortbay.jetty.AbstractGenerator$OutputWriter.write(AbstractGenerator.java:752) at java.io.PrintWriter.write(PrintWriter.java:412) at java.io.PrintWriter.write(PrintWriter.java:429) at org.ajax4jsf.io.parser.ParsingContext.sendBuffer(ParsingContext.java:118) at org.ajax4jsf.io.parser.ParsingContext.send(ParsingContext.java:131) at org.ajax4jsf.io.parser.FastHtmlParser.parse(FastHtmlParser.java:162) at org.ajax4jsf.io.parser.FastHtmlParser.parseHtml(FastHtmlParser.java:230) at org.ajax4jsf.webapp.FilterServletResponseWrapper.parseContent(FilterServletResponseWrapper.java:594) at org.ajax4jsf.webapp.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:367) at org.ajax4jsf.webapp.BaseFilter.handleRequest(BaseFilter.java:290) at org.ajax4jsf.webapp.BaseFilter.processUploadsAndHandleRequest(BaseFilter.java:388) at org.ajax4jsf.webapp.BaseFilter.doFilter(BaseFilter.java:515) at org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1157) at org.mortbay.jetty.servlet.ServletHandler.handle(ServletHandler.java:388) at org.mortbay.jetty.security.SecurityHandler.handle(SecurityHandler.java:216) at org.mortbay.jetty.servlet.SessionHandler.handle(SessionHandler.java:182) at org.mortbay.jetty.handler.ContextHandler.handle(ContextHandler.java:765) at org.mortbay.jetty.webapp.WebAppContext.handle(WebAppContext.java:418) at org.mortbay.jetty.handler.ContextHandlerCollection.handle(ContextHandlerCollection.java:230) at org.mortbay.jetty.handler.HandlerCollection.handle(HandlerCollection.java:114) at org.mortbay.jetty.handler.HandlerWrapper.handle(HandlerWrapper.java:152) at org.mortbay.jetty.Server.handle(Server.java:326) at org.mortbay.jetty.HttpConnection.handleRequest(HttpConnection.java:542) at org.mortbay.jetty.HttpConnection$RequestHandler.headerComplete(HttpConnection.java:923) at org.mortbay.jetty.HttpParser.parseNext(HttpParser.java:547) at org.mortbay.jetty.HttpParser.parseAvailable(HttpParser.java:212) at org.mortbay.jetty.HttpConnection.handle(HttpConnection.java:404) at org.mortbay.io.nio.SelectChannelEndPoint.run(SelectChannelEndPoint.java:409) at org.mortbay.thread.QueuedThreadPool$PoolThread.run(QueuedThreadPool.java:582) {noformat}
