JSF: problems downloading files using the Icefaces component

I am trying to get a FileUpload function that works with Icefaces ace: fileEntry , but my fileUploadListener not being called on the server, here is the code:

xhtml:

 <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:ace="http://www.icefaces.org/icefaces/components" xmlns:ice-cc="http://www.icesoft.com/icefaces-composite-comps" xmlns:f="http://java.sun.com/jsf/core" xmlns:ice="http://www.icesoft.com/icefaces/component"> <h:head> <link rel="stylesheet" type="text/css" href="/xmlhttp/css/rime/rime.css"/> </h:head> <h:body> <h:form enctype="multipart/form-data"> <ace:fileEntry id="fileEntryComp" label="File Entry" relativePath="uploaded" fileEntryListener="#{fileUpload.uploadFile}"/> <h:commandButton value="Upload File"/> </h:form> </h:body> </html>

java

 public void uploadFile(FileEntryEvent event) { FileEntry fileEntry = (FileEntry) event.getSource(); FileEntryResults results = fileEntry.getResults(); for (FileEntryResults.FileInfo fileInfo : results.getFiles()) { if (fileInfo.isSaved()) { log.debug("########### FILE IS SAVED ########"); } } }

Now, in the current state, I can open the file system navigation popup and I can select the file, but then fileUploadListener should be clicked, but now it’s not, I can also get some data that I installed on the server side, so the server side the work only works with the question, do I have fileUploadListener missed, any suggestions?

Update I'm still looking for an answer, since I could not successfully upload the file to the server.

Update 2 Now I get a Content is not allowed in prolog , not sure what exactly this means, here is stacktrace:

  ERROR [Faces Servlet] - Servlet.service() for servlet Faces Servlet threw exception: javax.faces.view.facelets.Facele tException: Error Parsing /trade_entry/UploadBlotter.xhtml: Error Traced[line: 2] Content is not allowed in prolog. at com.sun.faces.facelets.compiler.SAXCompiler.doCompile(SAXCompiler.java:417) [:2.1.7-SNAPSHOT] at com.sun.faces.facelets.compiler.SAXCompiler.doMetadataCompile(SAXCompiler.java:400) [:2.1.7-SNAPSHOT] at com.sun.faces.facelets.compiler.Compiler.metadataCompile(Compiler.java:130) [:2.1.7-SNAPSHOT] at com.sun.faces.facelets.impl.DefaultFaceletFactory.createMetadataFacelet(DefaultFaceletFactory.java:327) [:2.1.7-SNAPSHOT] at com.sun.faces.facelets.impl.DefaultFaceletFactory.access$200(DefaultFaceletFactory.java:93) [:2.1.7-SNAPSHOT] at com.sun.faces.facelets.impl.DefaultFaceletFactory$2.newInstance(DefaultFaceletFactory.java:166) [:2.1.7-SNAPSHOT] at com.sun.faces.facelets.impl.DefaultFaceletFactory$2.newInstance(DefaultFaceletFactory.java:164) [:2.1.7-SNAPSHOT] at com.sun.faces.facelets.impl.DefaultFaceletCache$2.newInstance(DefaultFaceletCache.java:94) [:2.1.7-SNAPSHOT] at com.sun.faces.facelets.impl.DefaultFaceletCache$2.newInstance(DefaultFaceletCache.java:89) [:2.1.7-SNAPSHOT] at com.sun.faces.util.ExpiringConcurrentCache$1.call(ExpiringConcurrentCache.java:99) [:2.1.7-SNAPSHOT]

I don't see any <h:form> surrounding your component, is there any in your code? I have no experience with icy surfaces, but I use richFaces. Via

 <rich:fileUpload immediate="true" id="fileUploadId" ajaxSingle="true" listHeight="70px" listWidth="500px" uploadButtonClass="otherButton" styleClass="backgroundColorInput" addButtonClass="otherButton" fileUploadListener="#{paramActions.fileUploadListener}"> <a:support event="onuploadcomplete" reRender="paramsForm" /> </rich:fileUpload>

he must be enclosed in

 <h:form id="paramsForm" enctype="multipart/form-data">
> multipart / form-data strong> enctype is required for fileUpload

In most cases, closed tags raise this exception. Check out xhtml, you can find any tag that opens.

for example: any open div or span ..

remove enctype="multipart/form-data" from h:form , it will work without it.

I had exactly this problem on the JBoss 7.1 server. I had an EAR project, several EJB projects, and several WAR projects. When I had a problem, I deployed the ice banks in the EAR library, but when I transferred them to the WAR project, which used the ace: fileentry, it started working.
