Spring application fails to load in STS 4.1

Posted on November 29, 2019 by Pandian Ramaiah

I have a spring web application which is running in Spring 5 (written in 3, later upgraded to 4 and 5 over the time). It was created in STS 2.x, later the workspace has been imported to STS 3.x without any problem. Though I have been using STS 4.1 for other SpringBoot projects, my old web application was still being developed in STS 3.x.

I imported the application to STS4.1 last week. The tomcat starts. But it does not load my application.

As you see in the above log, Spring context never loaded. When I tried to load the application URL, it was throwing HTTP Status 404 – Not Found error.

I had faced this kind of problem in earlier version of STS/Eclipse. It would be resolved either by tomcat server configuration or maven update or rebuilding or restart of eclipse. This was not resolved by either of these techniques and drove me crazy for two days.

I found one of the sites was showing the bug in STS 4.x which was fixed in 4.2. So, I want to try this as well. I tried to upgrade. Upgrade went well. But it didnt solve the problem. later I deleted the whole STS folder and used a fresh 4.4.0.RELEASE. Everything went smooth.. 😅😅

Nice picture, isn’t it? I captured it at the Temple of tooth, Kandy (6 Jun 19)

-Dmaven.multiModuleProjectDirectory system propery is not set

Posted on January 1, 2016 by Pandian Ramaiah

This is an error when I do the maven build for my new project.

This nasty error stopped my build.

“-Dmaven.multiModuleProjectDirectory system propery is not set”

Here is the error and how it was resolved.

Spring 4 MVC – 100% annotation based configuration

Posted on April 25, 2015 by Pandian Ramaiah

We have seen different Hello World for Spring 4 earlier posts.

I am trying to minimise the XML config as much as possible. Here is the way for a Spring 4 MVC environment purely based on java annotations.

Have the following ready –

JDK 8 x64 (1.5 may not work as expected)
Tomcat 8 x64
Spring 4 – Maven dependencies are given in this post.
STS or Eclipse latest version

WebApplicationInitializer

We are not using web.xml boss. So lets make write the WebApplicationInitializer first!

Create a dynamic web project in STS or Eclipse. Write the initializer code first. This defines the web application initializer for Tomcat. This defines our spring controller servlet “SpringDispatcher”. Happy?

package org.grassfield.conf;

import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.ServletRegistration;

import org.springframework.web.WebApplicationInitializer;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
import org.springframework.web.servlet.DispatcherServlet;

public class SpringWebAppInitializer implements WebApplicationInitializer {

    @Override
    public void onStartup(ServletContext container) throws ServletException {
        AnnotationConfigWebApplicationContext appContext = new AnnotationConfigWebApplicationContext();
        appContext.register(ApplicationContextConfig.class);

        ServletRegistration.Dynamic dispatcher = container.addServlet(
                "SpringDispatcher", new DispatcherServlet(appContext));
        dispatcher.setLoadOnStartup(1);
        dispatcher.addMapping("/*");
    }

}

WebMvcConfigurerAdapter

Friends, write your view logic here. Lets use simple viewResolver for this purpose. My controllers will send me the name of the view. I’ll choose the right jsp inside the /WEB-INF/views. Here you go! Please note the annotations @Configuration @EnableWebMvc @ComponentScan

package org.grassfield.conf;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;

@Configuration
@EnableWebMvc
@ComponentScan(basePackages={"org.grassfield.conf"})
public class ApplicationContextConfig extends WebMvcConfigurerAdapter{

    @Bean(name = "viewResolver")
    public InternalResourceViewResolver getViewResolver() {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setPrefix("/WEB-INF/views/");
        viewResolver.setSuffix(".jsp");
        return viewResolver;
    }
}

Request Handler

Let’s have a simple servlet first! This controller will handle the request pattern / and redirects the request to the view ‘home’. Please note the annotations @Controller @RequestMapping

package org.grassfield.conf;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class HomeController {

    @RequestMapping("/")
    public ModelAndView handleRequest(HttpServletRequest arg0,
            HttpServletResponse arg1) throws Exception {
        return new ModelAndView("home");
    }
}

View Jsp

Lets write the jsp to show the output in /WEB-INF/views/home.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"     pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"     "http://www.w3.org/TR/html4/loose.dtd">

Eclipse : Invalid project description

Posted on January 13, 2008 by Pandian Ramaiah

Hi,

This is a headache. I am using Eclipse 3.2. I have chosen, say, c:test as my work directory, then I couldnt create a project in any of those subdirectories, If I choose c:testproject as my project folder and I click Finish, I am getting the above error:

“Invalid project description.

C:testproject overlaps the workspace location: C:test

Later I found the reason from one of the forums.

Re: Invalid project description error message returned when importing projects.
It was not valid in Eclipse 3.1 for a project to be stored in a
sub-directory under the workspace directory. The 26 project directories
need to be moved up to the “workspace” directory, or the “agprojects”
directory needs to be moved outside the workspace directory. This
restriction is being lifted in Eclipse 3.2.

He says it has been lifted. but still i am in trouble….!!

Bye Bye NetBeans

Posted on August 30, 2006 by Pandian Ramaiah

I read an interesting log at “Xyling Java Blog”. He is complaining Netbeans consumes lot of memory even in legacy systems. I dont know about this becaz i’m an obliged Eclipse user. But the article is really interesting 🙂

here is the link,
