Using Java Advanced Imaging with Maven

Question

The JAI setup is quite tedious, involving multiple jars and environment variables. It would aid the project's portability quite a lot if I could add it as a regular Maven dependency.

The POM snippet I'm using is

<dependency>
  <groupId>com.sun.media</groupId>
  <artifactId>jai_imageio</artifactId>
  <version>1.1</version>
</dependency>

and the errors are

[INFO] ------------------------------------------------------------------------                               
[ERROR] BUILD ERROR                                                                                             
[INFO] ------------------------------------------------------------------------                                 
[INFO] Failed to resolve artifact.                                                                              

Missing:   
----------
1) com.sun.media:jai_imageio:jar:1.1
2) javax.media:jai_core:jar:1.1.3

I can, of course, download and install those jars. The problem is twofold:

• jai_imageio requires two jars;
• jai_imageio requires a native library to be installed and two environment variables to be set.

I have not found a way to make this work with Maven.

Answer 1

You're going to need to download the jars and install them in your local maven repository, or local repository proxy server (Nexus/Artifactory). I think you can use the maven-enforcer-plugin to validate that the environment settings are there.

The licence for jai_imageio doesn't allow for it to be distributed.

Answer 2

What I failed to see was that the JAI dependency needed to be satisfied only at runtime, and therefore I made sure the production environment has access to JAI, by configuring it for Tomcat.

Answer 3

try this:

<dependency>
  <groupId>com.sun.media</groupId>
  <artifactId>jai_imageio</artifactId>
  <version>1.1</version>
  <type>pom</type>
</dependency>
