When i am executing this program getting problem like

org.apache.commons.fileupload.FileUploadBase$InvalidContentTypeException: the request doesn't contain a multipart/form-data or multipart/mixed stream, content type header is application/x-www-form-urlencoded

[Added code tags - see UseCodeTags]

[Bear Bibeault]

Well, is the request a multi-part form? If not, it must be. See the JspFaq for more details on file uploading.

when i used enctype="multipart/form-data" in form tag i am not getting input type="text" values . Can any one help me.How can i get input type="text" values when i am using enctype="multipart/form-data" in form tag.

[Bear Bibeault]

Read the javadoc -- the getParameter() class of methods will not work with multi-part forms.

What upload library are you using? Its documentation will tell you how to get submitted values.

hi ..

why don't you use : the following packages .. (need to download seperately -not present in jdk software they belongs to javazoom api , used for file uploading and downloading)
but before that you need to use struts.jar,cos.jar,uploadbean.jar(please set the JAR files in CLASSPATH,please don't forget)
and try to use :

MultipartFormDataRequest nreq=new MultipartFormDataRequest(request);//represents form data along with uploaded files

and follwoing package import statements:

 import javazoom.upload.MultipartFormDataRequest;
 import javazoom.upload.UploadBean;
 import javazoom.upload.UploadParameters;

Please try with above.. If I am wrong , please correct me..

[Swetha Bhagavathula]

hope this is also helpful , you need to use "UploadBean" class and try like this by modifying your code:

		UploadBean upb=new UploadBean();
				//setting related photo uploading
				upb.setFolderstore(photoPath);
				upb.setOverwrite(false);
				upb.store(nreq,"tphoto");// completes file uploading of photograph
				

the above is one the ways where we can upload the pictures and documents..
