Plain text shows Encoded Chars

leave a comment »

Just started to have a chance to try out Spring 3.0, a lot of new features introduced, yet not enough time to read up all features.

I started a simple web apps project to try out Spring 3.0. The web apps is pretty simple, a REST server alike. Client init HTTP calls to the web apps with specific Servlet name and parameter, the web apps will returns the result JSON with Plain text mode. Since I am using Spring MVC, the result is printed with JSTL.

Sample call from client:

Expected result from server:

I get what I expected when I test my web apps with browser.

But the ‘interesting’ comes when I test it with little Java Post program (use HttpClient, init HTTP call and inspect the result).
I did not get the expected result, I get below:

All double-quat / quotation being replaced with ", its clearly the contain is being HTML encoded.

Below are my trouble-shooting steps:
Step 1. Check tomcat configuration
– Ensure the tomcat UTF-8 by default. More info
Step 2. Check web apps JSPs
– Ensure all JSP are UTF-8 as default encoding.

But both Step 1 & 2 does not fix my problem yet.
Step 3. Google “jstl without html encoded”
– Finally, I get the answer 🙂
– add in escapeXML properties when printing the result in JSTL
Before: <c:out value="${result}" />
After: <c:out value="${result}" escapeXml=”false”/>
Tutorial – Output with / without Encode

Lesson Learn:
When you want to print a PLAIN TEXT with JSTL, do remember to include escapeXML="false" to ensure that end user will get the actual expected result without HTML/XML encoded.

Html Form | GET vs POST

leave a comment »

Some simple stuff that a lot developers may mixup / confuse about — POST vs GET.

POST and GET are the most common use FORM submittion method used in html, as long as you’re working / doing in web application; you cant runaway from it.

Here is the simple comparison:


  1. Form data will appear within a message body.
  2. More functionality: retrieves, stores, updates data, makes modifications to databases, and so on.
  3. Not cacheable.
  4. Can buffer long URLs.
  5. Considered more secure.


  1. Form data is encoded by the browser into a URL.
  2. Best used for retrieving data.
  3. Cacheable.
  4. Cannot buffer long URLs.
  5. Considered less secure.
