Image upload in ADF

Image upload in ADF

In this post we will see how to upload images in Oracle ADF application.

To upload a file don't forget to set UsesUpload property of form of jspx page to true.

Lets start with uploading a image/file from client to the server.
ADF rich faces provide the tag af:inputFile to allow uploading of data.
Define a variable Type UploadedFile and create its accessors

private UploadedFile _file;

public void setFile(UploadedFile _file) {
this._file = _file;
}

public UploadedFile getFile() {
return _file;
}
And bind it with inputFile component's value property

<af:inputFile label="Upload Image" id="if1" value="#{ImageUploadBean.file}" />

In this we will see 2 places where we can uploading image depending on our requirement :-

1.) In Database(BLOB) :-
In this part, we will see how to upload a image/file from the client to and store image in a blob column in a database.

We have used button action to upload file

Following are codes to upload Image in database blob column

public String UploadImageAction() {
UploadedFile myfile = this.getFile();


if (myfile != null) {

if (myfile.getContentType().equalsIgnoreCase("image/jpeg") || myfile.getContentType().equalsIgnoreCase("image/png") || myfile.getContentType().equalsIgnoreCase("image/gif")
){

AppImageAMImpl am = (AppImageAMImpl)resolvElDC("AppImageAMDataControl");
ViewObjectImpl v = am.getAppImgAdd();
AppImgAddVORowImpl currRow = (AppImgAddVORowImpl)v.getCurrentRow();

try {


//to save image in Blob column in database directory..............


currRow.setImgBlob(createBlobDomain(getFile()));


} catch (Exception ex) {

}
}
}
setFile(null);
return null;
}


private BlobDomain createBlobDomain(UploadedFile file) {

InputStream in = null;
BlobDomain blobDomain = null;
OutputStream out = null;

try {
in = file.getInputStream();

blobDomain = new BlobDomain();
out = blobDomain.getBinaryOutputStream();
byte[] buffer = new byte[8192];
int bytesRead = 0;

while ((bytesRead = in.read(buffer, 0, 8192)) != -1) {
out.write(buffer, 0, bytesRead);
}

in.close();

} catch (IOException e) {
e.printStackTrace();
} catch (SQLException e) {
e.fillInStackTrace();
}

return blobDomain;
}

2.) In Actual path in server :-

In this part, we will see how to upload a image/file from the client to actual location in server.

public String UploadImageAction() {
UploadedFile myfile = this.getFile();

if (myfile != null) {

if (myfile.getContentType().equalsIgnoreCase("image/jpeg") || myfile.getContentType().equalsIgnoreCase("image/png")
|| myfile.getContentType().equalsIgnoreCase("image/gif")
){

String path = "D:\\Images\\";

if(myfile.getContentType().equalsIgnoreCase("image/jpeg")){

TypeVal=".jpeg";
}
else if(myfile.getContentType().equalsIgnoreCase("image/png")){

TypeVal=".png";
}

else if( myfile.getContentType().equalsIgnoreCase("image/gif")){

TypeVal=".gif";
}

AppItemImageAMImpl am = (AppItemImageAMImpl)resolvElDC("AppItemImageAMDataControl");
ViewObjectImpl v = am.getAppItmImgAdd();
AppItmImgAddVORowImpl currRow = (AppItmImgAddVORowImpl)v.getCurrentRow();

String ImgId = currRow.getImgId();

try {

InputStream inputStream = myfile.getInputStream();
BufferedImage input = ImageIO.read(inputStream);

//to save image in another directory..............

File outputFile = new File(path + ImgId + TypeVal);
ImageIO.write(input,type, outputFile);

} catch (Exception ex) {
// handle exception

}
}
}
setFile(null);
return null;
}
