File Uploading

[Joe Ridener]

Hello,

I am in the middle of a tutorial on Struts II. Although I have gone all over trying to get this program up and running I am still having the same exact problem and would have to believe that it is common. The error is that the it is not setting the File object in my sub-class of ActionSupport. my server console almost always says

INFO: Unable to find 'struts.multipart.saveDir' property setting. Defaulting to javax.servlet.context.tempdir

My Struts XML says this:

<struts> <constant name="struts.multipart.saveDir" value="javax.servlet.context.tempdir" /> <package name="FileUploader" extends="struts-default"> <action name="upload" class="net.joer.fileupoads.MyFileUploader"> <interceptor-ref name="fileUpload"> <param name="allowedTypes">text/plain,image/jpeg,image/gif,image/jpg</param>// cannot tell you that this is being read properly <interceptor-ref and its nested tags <param name="maximumSize">10000000</param> </interceptor-ref> <result name="success">showFiles.jsp</result> <result name="input">upload.jsp</result> </action> </package> </struts>

My Java Source code

public class MyFileUploader extends ActionSupport
{
    private File file;
    private String contentType;
    private String fileName;

    @Override
    public String execute() throws Exception {
        
        System.out.println(this.fileName);
        System.out.println(this.contentType);
        
        if(this.file == null)
            return INPUT;
        
        return SUCCESS;
    }

    public File getFile() {
        return file;
    }

    public String getContentType() {
        return contentType;
    }

    public String getFileName() {
        return fileName;
    }
    
    public void setMyUploadFileName(String fileName)
    {
        this.fileName = fileName;
    }

    public void setMyUploadContentType(String contentType)
    {
        this.contentType = contentType;
    }
        
    public void setMyUpload(File file)
    {
        this.file = file;
    }
}

I just threw this together very quickly. In previous attempts i followed the fileUpload's naming conventions far more strictly and still had the same result. So even though many of you may mention this it is most likely not the problem.

Oh yeah I forgot to mention that the File object is always null and does not exist.

I know little about Struts, but my first check would be that "javax.servlet.context.tempdir" points to a directory that can be read and written by whatever user account the servlet container runs under, and that no security manager interferes with that.

Close ... turned out the problem was you have to nest the interceptor-ref's a certain way. But my program does run now. And yes I created an images directory and download to there and it is better.


Thanks
