While trying to write a text file to the database, I get the following exception :
org.hibernate.InvalidMappingException: Could not parse mapping document
from resource hibernate.hbm.xml
as soon as I click the html submit button :
<form method="post" enctype="multipart/form-data" action="FileHandler">
<input type="file" name="file" /> <br />
<input type="submit" value="submit" />
</form>
I don't know the reason for why am I getting it. Following is the hibernate mapping file :
<hibernate-mapping>
<class name="pojo.File" table="b_files"/>
<id name="serial_number">
<generator class="increment" />
</id>
<property name="file" />
</hibernate-mapping>
Following is the class inside the pojo package (The mapping class) :
package pojo;
public class File {
private byte file[] = new byte[5120];
private int serial_number;
public int getSerial_number() {
return serial_number;
}
public void setSerial_number(int serial_number) {
this.serial_number = serial_number;
}
public byte[] getFile() {
return file;
}
public void setFile(byte[] file) {
this.file = file;
}
}
I used the this command to make a table named b_files :
create table b_files(files_uploaded mediumblob, serial_number integer);
Note : What I guess, is a problem with a property named 'file' in the mapping file. Is that Okay ? Because I do not get 'file' as a hint in my netbeans IDE. So I guess that it may the problem.
