How to add functionality from a JAR to an application?

0
I would like to add functionality from Free Spire (https://www.e-iceblue.com/Download/presentation-for-java-free.html) to my application Just wondering how easy it is to install this whole package? It's a JAR file and I can't seem to find proper instructions on how to add this to my app. Can anyone point me to a suitable source? Almost all the links on the forum are wrong and lead to sites that don't exist

TL;DR; the jar has no dependencies . You can just download it and put it into userlib/ . Here’s the direct link https://repo.e-iceblue.com/nexus/content/groups/public/e-iceblue/spire.presentation.free/5.1.0/spire.presentation.free-5.1.0.jar

 

 

To download a jar with all dependencies you also need to download  apache-maven-3.9.3-bin.zip at https://maven.apache.org/download.cgi

and then follow https://maven.apache.org/install.html

The important part is “ Have a JDK installation on your system. Either set the JAVA_HOME “

 

You already have OpenJDK installed at C:\Program Files\AdoptOpenJDK\

jdk-11.0.3.7-hotspot\

 

Set JAVA_HOME and PATH using the dialog “Change my environment variables” (shortcut win-r,

rundll32.exe sysdm.cpl,EditEnvironmentVariables

)

 

Create an xml file, name it pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

Open command prompt where pom.xml is saved and run this command: mvn package

 

It will download the jar and its dependencies into target\bar-0.1-SNAPSHOT\WEB-INF\lib\

Honestly? It doesn't have much to do with "low-code" :P
 

But of course I tried it and unfortunately it doesn't work. I tested it with mvn -v and I get the message

The JAVA_HOME environment variable is not defined correctly,
this environment variable is needed to run this program.

And it looks like it is installed correctly
