Spring Boot app deployed to Glassfish is giving strange results

Question

As mentioned here, I am having a heck of a time getting my small Spring-Boot project to deploy \"correctly\" to Glassfish. It runs fine using the embedded Tomcat, but once

Answer 1

I had this problem with Payara 5, I understand the problem became from Glassfish.

Versions:

1. Payara 5.192
2. Spring Boot 2.1.6

The solution worked for me:

I added this dependency in the pom.xml.

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-batch</artifactId>
    <version>2.1.4.RELEASE</version>
</dependency>

My glassfish-web configuration:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE glassfish-web-app PUBLIC ...>
<glassfish-web-app error-url="">
    <class-loader delegate="true"/>
    <jsp-config>
        <property name="keepgenerated" value="true">
          <description>Keep a copy of the generated servlet class' java code.</description>
        </property>
      </jsp-config>
    <!-- set a friendly context root -->
    <context-root>/micuenta-api</context-root>
    <!-- Change the default character encoding from ISO-8859-1 to UTF-8 -->
    <parameter-encoding default-charset="UTF-8"/>
</glassfish-web-app>

There is a bug in Glassfish 3.1.X. You need to include metadata-complete="true" in your web.xml root element.

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.1" 
     metadata-complete="true"
     xmlns="http://xmlns.jcp.org/xml/ns/javaee" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd">
</web-app>
