Intellij Spring Boot JSP Page not found or too many redirects

Intellij IDEA - the leading Java IDE

This is a bug in IntelliJ version 2021.3 probably gonna be fixed in the future release version of IntelliJ. So, if you have a similar problem, maybe this can fix it.

The error usually shows up as page Not found or too many redirects, when you run spring boot code with JSP template using the Intellij run icon.

Here’s a simple quick fix to solve it:

- Go to the run Edit configuration
- Select Modify option
- Select a Working directory
- And put this variable:
$MODULE_DIR$ 
- Then run once again

It is not something wrong with your code, JSP codes, if you debug it you will see that everything just works. Even if you are using the spring-boot maven plugin, like doing mvn spring-boot:run the program just works fine.

Sometimes we need to debug our project using the IntelliJ debugging feature, which is impossible to do by just using the maven spring-boot plugin. So we need to run the program using the IDE.

I hope this can fix and solve your problem, so you can continue on things that matter.

Intellij is a very powerful Java IDE, it is heavy-weight, and most professional developers use it as their main code editor for developing their projects. Check out this link to download the newest version of Intellij IDEA here.

MySQL and MariaDB password As already mentioned in the title of this blog, this error message sometimes occurred when we are trying to update our root password database, either MySQL or MariaDB, The error says: ERROR 1348 (HY000): Column 'Password' is not updatable This is because if we use this SQL command to update our database root password, and it turn out to be Restricted by MySQL to use update on mysql database. UPDATE mysql.user SET Password=PASSWORD('1234') WHERE User='root'; The solutions for MySQL Error1348 So you can not update a user password using Update commands, to update the password, use ALTER commands instead. like the following.

Spring Boot is a handy tool that simplifies the development of Spring Framework applications by reducing the need for cumbersome configuration. In this tutorial, I'll guide you through creating a Spring Boot application using the Netbeans IDE. While you can certainly create a Spring Boot application in Netbeans manually, it's much easier with a plugin designed for Spring development. Here's a step-by-step guide to get you started: 1. Install the Spring Boot Plugin: Open Netbeans and navigate to the Tools menu. Click on "Plugins." Once the Plugins window opens, select the "Available Plugins" tab.

Go to File > New Project. Under Categories, select Maven, then choose "Spring Boot Basic." 3. Add Dependencies: With your new project created, open the po...

Spring Kafka - How to use ReplyingKafkaTemplate send and reply synchronously

Microservice Spring with Apache Kafka Today, I want to share how to use Kafka. It's quite interesting once you get the hang of it, and I hope my explanation will make it a bit easier for you. So, Kafka is primarily known as an asynchronous messaging queuing system. This means it allows different parts of your application to communicate with each other without waiting for immediate responses. However, there are times when you might need a more immediate reply from another service in your project. Luckily, Kafka can handle this too. Here’s how it works: The client side sends a message to the server side via Kafka. This message includes a special identifier in the Kafka header request, known as KafkaHeaders.CORRELATION_ID, along with a topic where the server should respond. The server, after processing the request, sends a message back to the same topic with the same correlation ID. This way, the client knows that the message is a response to its initial request and can act accordingl...
