ADF: Using Input Range Slider (RichInputRangeSlider)

Input Range Slider is one of the coolest components of ADF which is not only very intuitive for users but also gives a 'cool' look to the page :)



So how do we get minimum and maximum values selected on the slider?

Among other properties of this component are 'minimum' and a 'maximum' and then there is 'value'. This causes some confusion as to  how can we get the values selected on the slider. This is not half as complex as it seems!

Let's focus first on the 'value'. The value of this component is returned in form of a oracle.adf.view.rich.model.NumberRange object.

oracle.adf.view.rich.model.NumberRange minMax = (oracle.adf.view.rich.model.NumberRange)getInputRangeSlider().getValue();

You can extract both the minimum and maximum values from this object like this:


        int startValue = minMax.getMinimum().intValue();
        int endValue = minMax.getMaximum().intValue();

and that's it. You have both the values returned by the slider.

'Minimum' and 'Maximum' attributes define the minimum and maximum values that your slider will show. By default minimum is 0 and maximum is 10 and the slider shows numbers from 0 to 10. You can set your own values programmatically for both the attributes.


minimum="#{pageFlowScope.MyBackingBean.minimumValue}"
maximum="#{pageFlowScope. MyBackingBean.maximumValue}"


and on runtime your slider will show the values set by these EL expressions.

Among other common properties are orientation and increment related properties using which you can change orientation of the slider from horizontal to vertical or change the minimum increment value to define minimum difference between minimum and maximum values.

So go on. Take this range slider out for a spin!

File upload problem: UTF-8 encoding not honored when form has multipart/form-data

The problem that I was facing was something like this. I was using Apache Commons File Upload library to upload and download some file.

I had a form in which user can upload a file and another field 'name' in which she can give any name to the file being loaded.


When I submitted the form, the file was uploaded fine but the value in name field was garbled. I followed all the possible suggestions I found:

<%@page pageEncoding="UTF-8"%> set. <%@page contentType="text/html;charset=UTF-8"%gt; set after the first directive. <meta equiv="Content-Type" content="text/html;charset=UTF-8"> in the head. enctype="multipart/form-data" attribute in the form. accept-charset="UTF-8" attribute in the form.
in the Servlet:
before doing any operations on request object: request.setCharacterEncoding("UTF-8"); For accessing the value

FileItem item = (FileItem) iter.next();

if (item.isFormField()) {

//For regular…

java.lang.IllegalArgumentException: Malformed \uxxxx encoding

I was getting this exception during build while running ant. Googling didn't help much and I was flummoxed because the same code was running fine till now.

My code reads a text file and does some operations on the basis of values read. It was only when I saw the text files I understood the error. I had copied the text in wordpad and saved it as .txt file. Wordpad had put lot of formatting information before and after the content. Also there was "\par" after every line, which was giving this error.

So moral of the story: if you get this exception check your properties file (or any other file that your code might be reading.)

How to upload to Google Cloud Storage buckets using CURL

Signed URLs are pretty nifty feature given by Google Cloud Platform to let anyone access your cloud storage (bucket or any file in the bucket) without need to sign in.

Official documentation gives step by step details as to how to read/write to the bucket using gsutil or through a program. This article will tell you how to upload a file to the bucket using curl so that any client which doesn't have cloud SDK installed can do this using a simple script. This command creates a signed PUT URL for your bucket. gsutil signurl -c 'text/plain' -m PUT serviceAccount.json gs://test_bucket_location
Here is my URL:
