upload problem
Hi,
I'm trying to upload an image with Cocoon. But when i'm trying to read the
parameters of the file in my Action it seems to be an String. What did I do
wrong?
I've the following form:
addresidence.xml
===================
<form action="addresidence.html" enctype="multipart/form-data">
<tr>
<td>
<input type="file" name="uploadfile" size="50"/>
<input type="submit"/>
</td>
</tr>
</form>
===================
web.xml
===================
<init-param>
<param-name>enable-uploads</param-name>
<param-value>true</param-value>
</init-param>
===================
myAction.java (extends AbstractXMLFormAction implements FormListener)
===================
import org.apache.cocoon.acting.AbstractXMLFormAction;
import org.apache.cocoon.components.xmlform.Form;
import org.apache.cocoon.components.xmlform.FormListener;
import org.apache.cocoon.servlet.multipart.Part;
.....
HashMap parameters = new HashMap();
Enumeration parametersEnum = getRequest().getParameterNames();
System.out.println("Voor de while");
while( parametersEnum.hasMoreElements() ){
String name = (String)parametersEnum.nextElement();
Object value = getRequest().getParameter( name );
System.out.println("Voor instanceof");
System.out.println("instance of: "+value.getClass().getName());
System.out.println("instance package: "+value.getClass().getPackage());
System.out.println("instance to string: "+value.toString());
if (value instanceof Part) {
System.out.println("Part");
}
parameters.put( name, value );
}
===================
sitemap.xmap
===================
<map:pipeline>
<map:match pattern="">
<map:redirect-to uri="overview.html"/>
</map:match>
<map:match pattern="wml/">
<map:redirect-to uri="../overview.wml"/>
</map:match>
<map:match pattern="overview.html">
<map:read src="overview.html"/>
</map:match>
<map:match pattern="overview.wml">
<map:read src="overview.wml"/>
</map:match>
<map:match pattern="img/*.gif">
<map:read src="img/{1}.gif" mime-type="image/gif" />
</map:match>
<map:match pattern="img/*.jpg">
<map:read src="img/{1}.jpg" mime-type="image/jpg" />
</map:match>
<map:match pattern="stylesheets/css/*.css">
<map:read src="stylesheets/css/{1}.css" mime-type="text/css " />
</map:match>
</map:pipeline>
<map:pipeline>
<map:match pattern="addresidence.*">
<map:act type="request">
<map:parameter name="parameters" value="true"/>
<map:act type="MyAction">
<map:generate src="upload.html"/>
<map:serialize type="html" label="debug"/>
</map:act>
</map:act>
</map:match>
</map:pipeline>
===================
I get the following output of my program:
-----
Voor de while
Voor instanceof
instance of: java.lang.String
instance package: package java.lang, Java Platform API Specification,
version 1.4
instance to string:
C:\jakarta-tomcat-4.1.12\work\Standalone\localhost\forms\cocoon-files\upload
-dir\group-logo.gif
-----
As you can see it's an instance of a String, but I expected an instance of a
Part. Can someone explain this?
When I look in the directory
C:\jakarta-tomcat-4.1.12\work\Standalone\localhost\forms\cocoon-files\upload
-dir\ there's no file available. What do I do wrong? Has it something to
with AbstractXMLFormAction? I'm deploying under tomcat. Do I've to change
some settings of it?
Many thanks for your time!
Kind regards,
Robert Kromkamp

By default, Cocoon (2.1) removes the file from the upload dir at the end
of the request, so you won't necessarily see it there. You can change
that behavior with autosave-uploads in web.xml.
Does your System.out report a Part object?
If so, then the problem is in what happens from there - you put it a
HashMap but what from there?
If not, you may be looking in the wrong "Request". What does
getRequest() do/return? (not familiar with AbstractXMLFormAction if it's
inherited). You may also want to double check that you edited the right
web.xml and that the changes did not get overwritten since. BTW, if you
are building from cvs there is a build property you can set with
local.build.properties to turn on uploads in a way that survives a
re-build. It's run by the custom-conf (customconf?) target and
documented at the wiki under xpatch task usage.

Thanks for your advice, I've changed it, but i still don't get a file. Ik
think the problem is there's no file in the directory
C;\jakarta-tomcat-4.1.12\work\Standalone\localhost\forms\cocoon-files\upload
. Should it be there?
Cheers,
Robert
