I am unable to understand why my spring boot is not rendering my jsp page. In my application.properties, I have
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
But still I am facing the following error as soon as I hit the URL:
org.apache.jasper.JasperException: Unable to compile class for JSP:

Please help me to resolve this issue. My jsp file is in src->main->webapp->WEB-INF->jsp->home.jsp. My controller is:
package com.example.JasperPractice.Controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ResponseBody;
#Controller
public class JasperController {
#GetMapping("/get-employee")
//#ResponseBody
public String getEmployees() {
return "hello";
}
}
And my home.jsp page is
<%# page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<h1>This is home</h1>
</body>
</html>
According to me, there is some problem in my jsp because as soon as I hit the URL "get-employee" then my error occurs
I figured it out myself... Actually the following dependency was causing error.
<dependency>
<groupId>net.sf.jasperreports</groupId>
<artifactId>jasperreports</artifactId>
<version>6.4.0</version>
</dependency>
Removing it solved my problem

I`m trying to learn Spring Boot but am having trouble with Rest API. i'm having a problem with creating restcontroller for my application. I'm trying to read data from database. It works fine when i use commandLineRunner inside main application class. While generating http request this error ocures:
HTTP/1.1 500
Content-Type: application/json
Transfer-Encoding: chunked
Date: Tue, 12 Jul 2022 12:23:00 GMT
Connection: close

"status": 500,
"error": "Internal Server Error",
"path": "/send"
}
Here is my controller:
package com.example.db.controller;
import com.example.db.model.Customer;
import com.example.db.model.CustomerUI;
import com.example.db.repository.CustomerRepository;
import org.springframework.web.bind.annotation.*;
import java.util.ArrayList;
import java.util.List;
#RestController
public class MessageController {
CustomerRepository repository;
#GetMapping("/send")
public List<CustomerUI> findAll(){
List<Customer> customers = repository.findAll();
List<CustomerUI> customerUI = new ArrayList<>();
for (Customer customer : customers) {
System.out.println(customer.toString());
}
return customerUI;
}
}

You have a null pointer at line 29, which I guess is the call to the repository, this means that your repository is not injected in the controller. This happens because you haven't allowed spring to inject it. Either make it final and add a constructor that will set it:
#RestController
public class MessageController {
private final CustomerRepository repository;
public MessageController(CustomerRepository repository) {
this.repository = repository;
}
...
Or add #Autowired on the repository field.
#Autowired
CustomerRepository repository;
First option is preferred as you can easily mock the repository in tests and doesn't use reflection to inject the fields.
You are sending an empty array list
#GetMapping(value = "/send")
public List<CustomerUI> findAll(){
List<Customer> customers = repository.findAll();
List<CustomerUI> customerUI = new ArrayList<>();
for (Customer customer : customers) {
System.out.println(customer.toString());
}
return customers;
}
I am following video series from here: https://app.pluralsight.com/course-player?clipId=5133b583-6d21-4f49-b069-95f5ae7a60d8 and last section is not quite working well for me. The only thing I changed is I'm using latest version of Spring Boot 2.7.0.

}
Almost the code is same
I can't see what's on the video, since i need to sign up but based on the stack trace it appears you are trying to use SpEL on the payload which exists in its raw format byte[]. That is about as much as I can say since I don't have a view into the application.
Consider creating a small sample in Github so we can clone and take a look to avoid the guessing game.
Hey everyone so I've made a camunda project in spring tool suite using maven and I'm trying to open it up in camunda local host: 8080. I've put the war file for the project in the web apps folder and deployed it but when I start camunda 2 cmd's opens up and it has a lot of text but then it closes and only one is left open and when I go to the local host 8080 it shows the home screen but if I click on task list or anything it doesn't work anymore and says the site can't be reached. I've looked in the log files and this is what it says:
SEVERE [http-nio-8080-exec-1] org.apache.catalina.core.StandardWrapperValve.invoke Servlet.service() for servlet [default] in context with path [/camunda] threw exception

What does this error mean and what can I do to fix it so that it works?
".getProcessEngine(String)" is null a" means the process engine did not boostrap correctly. Search further in the console output to find the underlying reason. Could be e.g. something related to the DB connection.
Alternatively create the project with https://start.camunda.com/
I have a question concerning JSF/PrimeFaces on TomEE. Running the following code (PrimeFaces 7.0)
<h:selectBooleanCheckbox value="#{dashboardUIController.includeMyself}">
<p:ajax event="change" listener="#{dashboardUIController.onIncludeMyself()}" update="teamVisitedCountriesChart teamTravelsForProjectsChart"/>
</h:selectBooleanCheckbox>
on TomEE version 8.0.6, everything is fine. Running it on TomEE version 8.0.8, it results in the following exception:

It seems that TomEE 8.0.8 includes a Mojarra version, which forbids an ajax inside a selectBooleanCheckBox element.
So, does anybody know the exact root cause of this exception, and also, how to get it running on TomEE 8.0.8?
Thanks!
