Stupid ajax4jsf filter when downloading files
Hi,
I was trying to use a typical seam backing bean for handling a file download. So i used the many examples posted on this forum. sthg like :
@Stateful
@Scope(EVENT)
@Name("editWebdoc")
public class EditWebdocAction implements EditWebdoc {
@In(required=true)
private Client client;
@In(required=false)
private Webdoc webdoc;
@In(value = "#{facesContext}")
private FacesContext mFacesContext;
....
public void getDocFichier(Webdoc webdoc) {
if (webdoc == null) {
return;
}
byte[] data = webdoc.getDocFicData();
HttpServletResponse response = (HttpServletResponse) mFacesContext.getExternalContext().getResponse();
response.setContentType("application/pdf");
response.setContentLength(data.length);
response.addHeader("Content-disposition", "attachment; filename=\"" + webdoc.getDocFicNom() + "\"");
try {
ServletOutputStream responseOutputStream = response.getOutputStream();
responseOutputStream.write(webdoc.getDocFicData());
responseOutputStream.flush();
responseOutputStream.close();
mFacesContext.responseComplete();
response.flushBuffer();
} catch (IOException ioe) {
log.error("IOException lors de la restitution du document webdoc", ioe);
}
AND
<s:fileUpload id="fichierPDF"
data="#{webdoc.docFicData}"
accept="application/PDF"
contentType="#{editWebdoc.fichierContentType}"
fileName="#{webdoc.docFicNom}"
fileSize="#{editWebdoc.fichierTaille}" />But i kept getting the following error :
17:35:40,872 ERROR [[Faces Servlet]] "Servlet.service()" pour la servlet Faces Servlet a généré une exception java.lang.NullPointerException at java.util.regex.Matcher.getTextLength(Matcher.java:1127) at java.util.regex.Matcher.reset(Matcher.java:284) at java.util.regex.Matcher.<init>(Matcher.java:205) at java.util.regex.Pattern.matcher(Pattern.java:879) at org.ajax4jsf.webapp.ParserConfig.getParser(ParserConfig.java:28) at org.ajax4jsf.webapp.ConfigurableXMLFilter.getParser(ConfigurableXMLFilter.java:109) at org.ajax4jsf.webapp.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:259) at org.ajax4jsf.webapp.BaseFilter.doFilter(BaseFilter.java:281) at org.jboss.seam.web.Ajax4jsfFilter.doFilter(Ajax4jsfFilter.java:60) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) at org.jboss.seam.web.LoggingFilter.doFilter(LoggingFilter.java:58) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) at org.jboss.seam.servlet.SeamFilter.doFilter(SeamFilter.java:150) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:230) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175) at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:179) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:84) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:128) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:104) at org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:156) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:241) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:580) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) at java.lang.Thread.run(Thread.java:595)
So i thought it was this stupid ajax4jsf filter and i switched the force-parser attribute to false hence ending up to this in components.xml :
<web:ajax4jsf-filter force-parser="true" enable-cache="true" log4j-init-file="custom-log4j.xml" url-pattern="*.seam"/>
The pdf download now works, but of course the ajax validation w/ hibernate validator is not working in the other pages of my application.
Can't we have both ajax-hibernate validation AND download file functionnality within the same application?
Is there a way to bypass ajax filter for certain actions?
