Using File Download Control with Java Bean in XPages -

-

i use standard xpages xp:filedownload control , bind java bean rather document source.

i have rtf field in form - 'resourceattachments' - along several other fields in in storing several attachments , nothing else.

can provide me example or point me documentation. have similar requirement xp:uploadcontrol, can find samples create new document, struggling implement adding , saving existing documents, guess should post question though, 2 go thought @ least mention here.

many thanks.

public class trainingmodule implements serializable { private static final long serialversionuid = -6998234266563204541l; private string description; private ????  resourceattachments;  --something here ?? private string unid;  public trainingmodule() {     string documentid = extlibutil.readparameter(facescontext.getcurrentinstance(), "key");     if (stringutil.isnotempty(documentid)) {         load(documentid);     } }  public string getunid() {return unid;} public void setunid(final string unid) {this.unid = unid;}  public string getdescription() {return description;} public void setdescription(final string description) {this.description = description;}  ? attachment getter & setter here??  public void load(final string unid) {setunid(unid);{     document doc = null;     try {         doc = extlibutil.getcurrentdatabase().getdocumentbyunid(getunid());         setdescription(doc.getitemvaluestring("description"));     ??some load here here??       } catch (throwable t) { t.printstacktrace();     } {         try {             doc.recycle();                         ?some other recycle here?         } catch (exception ) {             // fail silent         }     }

in custom control amongst other things have...

 <xp:this.beforepageload><![cdata[#{javascript:if(param.containskey("key"))    {viewscope.put("docattach",(param.get("key")));}}]]></xp:this.beforepageload> .......  <xp:filedownload rows="30" id="filedownload2" displaylastmodified="false"  value="#{trainingmodule.resourceattachments}" hidewhen="true" allowdelete="true">                 </xp:filedownload>

i have dealt similar problem last year. haven't looked appropriate binding fileupload. instead, used different approach.

when submit xpage file upload, upload file disk (regardless of binding) , create com.ibm.xsp.http.uploadedfile object in requestmap. can grab bean method , magic.

this ibm connect 2014 demo , have used technique upload file basecamp.

xsp code simple (here github repo)

<xp:fileupload id="fileupload1"></xp:fileupload>  <xp:button id="button1"     value="upload local file">     <xp:eventhandler event="onclick"         submit="true" refreshmode="complete">         <xp:this.action>             <xp:executescript                 script="#{bcs.uploadlocalfile}">             </xp:executescript>         </xp:this.action>     </xp:eventhandler> </xp:button>

bcs managed bean , here code snippet upload (from github repo)

public void uploadlocalfile() {      facescontext facescontext = facescontext.getcurrentinstance();     externalcontext externalcontext = facescontext.getexternalcontext();      httpservletrequest request = (httpservletrequest) externalcontext.getrequest();      string fileuploadid = extlibutil.getclientid(facescontext, facescontext.getviewroot(), "fileupload1", false);      uploadedfile uploadedfile = ((uploadedfile) request.getparametermap().get(fileuploadid));      if (uploadedfile == null) {         facescontext.addmessage("messages1", new facesmessage(facesmessage.severity_error, "no file uploaded. use file upload button upload file.", ""));         return;     }      java.io.file file = uploadedfile.getserverfile();     string contenttype=uploadedfile.getcontenttype();     string filename = uploadedfile.getclientfilename();      // removed unrelated code...  }

so, basically, requestmap. uploadedfile object refers file object has been uploaded temporary area on server , it's mapped clientid of fileupload component.

after point, might create stream , attach file field. when bind field, document wrapper same thing, guess.
