Error while configuring Spring with FreeMarker

Today I got a strange problem while configuring FreeMarker with Spring. The project compiles well without any error. All seems to be fine. When I tried to run the application strangely I got following error:

Spring in Action, 4ed (Manning)

java.lang.NoSuchMethodError: freemarker.template.Configuration. Lfreemarker/template/Version;)V

Now for struggling and googling for around one hour I got the answer :)

Instant FreeMarker Starter

I am using Spring 4.3.5.RELEASE and FreeMarker 2.3.20 before I found the answer. This isstrange but the actual problem lies with the version compatibility of FreeMarker with Spring. It seems that Spring had some issues with FreeMarker.

After changing the FreeMarker version from 2.3.20 to 2.3.23 all works fine.
Hope this solution help the developers out there configuring FreeMarker with Spring.

Enjoy coding!

Getting height and width of image in Java

Yesterday I was working on something that requires manipulation of image for getting its properties. After searching over the internet I found a very intersting class on Java i.e ImageIO and BufferedImage class. These classes are good enough to manipulate images. there are many other claases also. But what I need i got it from these. I found many developers searching over internet for getting properties of image and there is no good small example for that. Thats why I thought why not creating a simple code to manipulate the image and help the developers. Here is the small code that helps to get the height and width of the image. Enjoy it!! import java.awt.image.BufferedImage; import java.io.File; import java.io.IOException; import javax.imageio.ImageIO; public class GetImage { public static void main(String[] args) { try { File f = new File("E:/Vinod/Docs/Pics/krishna_01.jpg"); BufferedImage image = ImageIO.read(f); int height = image.getHeight(); in

SSL in Spring Boot using GoDaddy certificate on EC2

In this article, we will be going to see how we can achieve the HTTPS in the spring boot application . You will get lots of items on how to use the self-generated certificate with Spring Boot. But today we are going to use the CA generated certificates with the Spring Boot so that our application will work on HTTPS. We need the following things to work: CA certificates including, private key and certificate. In this article, we are using the GoDaddy wild card certificate. Spring Boot application OpenSSL library Convert the certificate and private key to PKCS 12 First of all, we need to convert the CA certificate to .p12 format . We need to have OpenSSL on the system to work with command. Also, we need to have all files in the same directory where we are running this command. The command required to covert the same: openssl pkcs12 -export -in [ceritificate-name] -inkey [private-key] -name [host] -out [new-file.p12] Here replace the values: [ceritificate-name] with

Struts 2 Ajax drop down Example

Struts 2 has emerged as boon for developers. But the documentation available is very small. So I had decided to give a brief demonstration of the ajax used in struts 2.1.8.1 Libraries used: commons-beanutils-1.7.0.jar commons-fileupload-1.2.jar commons-logging-1.1.jar commons-logging-api-1.1.jar freemarker-2.3.8.jar struts2-core-2.1.8.1.jar struts2-dojo-plugin-2.1.8.1.jar xwork-core-2.1.6.jar In this example when u select from one drop down the other will populate accordingly. You can use it as it is or play with it. Enjoy !! index.jsp <%@ taglib prefix="s" uri="/struts-tags" %> <s:action name="ListingAction" executeResult="true"></s:action> listing.jsp <%@ taglib prefix="s" uri="/struts-tags"%> <%@ taglib prefix="sx" uri="/struts-dojo-tags"%> Listing detail.jsp <%@ taglib prefix="s" uri="/struts-tags"
