Re:NOT-SOLVED....WHY?? Re: Cocoon File upload HELP
Hi.
Yes i have enable all; this is my cocoon-servlet configuration in web.xml:
<servlet>

</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
This is my form definition:
<?xml version="1.0"?>
<fd:form xmlns:fd="http://apache.org/cocoon/forms/1.0#definition" xmlns:i18n="http://apache.org/cocoon/i18n/2.1">
<fd:widgets>
<fd:field id="user" required="false">
<fd:datatype base="string"/>
<fd:label>Inserire il file XPDL da uploadare</fd:label>
</fd:field>
<fd:upload id="upload" mime-types="text/xml" required="true">
<fd:label>File da uploadare</fd:label>
<fd:hint>Scegliere un file di tipo XPDL o XML</fd:hint>
</fd:upload>
</fd:widgets>
</fd:form>
This is my Template:
<?xml version="1.0"?>
<page xmlns:jx="http://apache.org/cocoon/templates/jx/1.0" xmlns:ft="http://apache.org/cocoon/forms/1.0#template" xmlns:fi="http://apache.org/cocoon/forms/1.0#instance">
<jx:import uri="resource://org/apache/cocoon/forms/generation/template.jx"/>
<title>Upload XPDL/XML file</title>
<content>
<para>Scegliere il descrittore XML o XPDL che si vuole caricare</para>
<ft:form-template action="#{$cocoon/continuation/id}.kont" method="POST" enctype="multipart/form-data">
<table>
<tr>
<td valign="top">
<ft:widget-label id="user"/>
</td>
</tr>
<tr>
<td valign="top">
<ft:widget-label id="upload"/>

<td valign="top">
<ft:widget id="upload">
<fi:upload/>
</ft:widget>
</td>
</tr>
</table><br/>
<input type="submit" value="Upload"/>
</ft:form-template>
</content>
</page>
and this is my flow script:
function upload() {
var log = Logger.getLogger( "it.eng.nikko.workflow.upload.js" );
log.info( "Sono quì" );
var form = new Form("forms/uploadForm.xml");
var k = form.showForm("uploadFile.jx");
log.info( "Starting upload......" );
//k.invalidate();
var uploadWidget = form.lookupWidget("upload");
log.info( "Ho ottenuto: ["+uploadWidget+"]" );
log.info( "uploadWidget.getValue(): "+ uploadWidget.getValue() );
log.info( "uploadWidget.value: "+ uploadWidget.value );
var content = handleUpload(form);
var fileName = form.lookupWidget("upload").getValue().getHeaders().get("filename");
log.info( "Upload finished....." );
cocoon.sendPage("uploadSuccess.jx",
{
uploadContent: content,
filename: fileName
}
);
}
function handleUpload(form) {
var log = Logger.getLogger( "it.eng.nikko.workflow.upload.js" );
log.info( "handleUpload" );
var buf = new java.lang.StringBuffer();
var uploadWidget = form.lookupWidget("upload");
log.info( "uploadWidget.getValue(): "+ uploadWidget.getValue() );
log.info( "uploadWidget.value: "+ uploadWidget.value );
if (uploadWidget.getValue() != null) {
log.info( "in if" );
var realPath = java.lang.System.getProperty( "realPath" );
var dir = new java.io.File( realPath+"/procDef/" );
if( !dir.exists() ){
dir.mkdirs();
}
var myFile = new java.io.File( dir, getFileName( uploadWidget.getValue() ) );
var writer = new java.io.PrintWriter ( new java.io.FileOutputStream( myFile ) );
var stream = uploadWidget.getValue().getInputStream();
var reader = new java.io.BufferedReader(new java.io.InputStreamReader(stream));
var line;
while ((line=reader.readLine())!=null){
buf.append(line).append("\n");
writer.println( line );
}
reader.close();
writer.close();
UploadXPDL.doUpload( myFile );
}else{
log.info( "Era nullo" );
}
return buf.toString();
}
function getFileName( path ){
var strTok = new java.util.StringTokenizer( path,"/" );
var workFlowFile = null;
while( strTok.hasMoreTokens() ){
var token = strTok.nextToken();
if( ( token.indexOf( ".xml" ) > -1 ) || ( token.indexOf( ".xpdl" ) > -1 ) ){
workFlowFile = token;
}
}
return workFlowFile;
}
I have started from cocoon samples. The proble is that even if i choose a file .xml the content of my input is null so i have a null pointer exception.. i really don't understand why.

does the directory XPDL exist in your webapp root ? is it writeable by
the servlet ?
try setting upload-directory to an absolute path which is writable. then
check if
your file is placed there by cocoon.
also, please send the html code of the overall generated form.

Johannes
