I am building an application that extracts the feature of an image and saves it to the database (using JSP, Java & PostgreSQL ).
I have based it on Caliph & Emir website. ( http://www.semanticmetadata.net/features/ )
I open PostgreSQL and the database it being automatically created. I created this project in NetBeans. I have loaded the Apache Tomcat plugin into NetBeans and I am running Apache Tomcat ( Catalina ) from cmd as well (even though I don't know if it is necessary ).
The thing is though that when the interface through my project opens, I can load an image through it but then despite getting a success comment out of it
( Successfully uploaded image "734961_10151351065770042_1001776232_n.jpg" at path "bla1/bla2/Project1/Me/WebApp/data/img/".
Successfully added image "bla1/bla2/Project1/Me/WebApp/data/img/".734961_10151351065770042_1001776232_n.jpg" at database.)
the images' features wont load into database.
This is manager_op.jsp code (manage operation) If an additional code excerpt is needed tell me and I will give it to you.
Because it is already too big, I will only place manager_op.jsp because I believe that the mistake is somewhere in here. But then again, I may be wrong. It may be an Apache issue (some setting that I didn't do or something else - and I think that is quite possible). Help me if you can. Thanks in advance.

Below is the code for addImage() and addAllImages() in my java file.
public int AddImage(String targetPath, String mFilename)
{
int r;
CloseConn();
r = ConnToDb();
if (r != 0) return r;
try {
_InsertImage(targetPath, mFilename);
} catch (Exception ex) {
r = -10;
}
CloseConn();
return r;
}
public int AddAllImages(String sImagesPath)
{
int r;
CloseConn();
r = ConnToDb();
if (r != 0) return r;
try {
String sFilename;
File folder = new File(sImagesPath);
File[] listOfFiles = folder.listFiles();
int iCount = 0;
if ((iCount <= 0) || (iCount > listOfFiles.length))
iCount = listOfFiles.length;
for (int i = 0; i < iCount; i++) {
if (listOfFiles[i].isFile()) {
sFilename = listOfFiles[i].getName();
_InsertImage(sImagesPath, sFilename);
}
}
} catch (Exception ex) {
r = -10;
}
CloseConn();
return r;
}
