Installing JMF with eclipse [message #255443]

Hi, i'm trying to use JMF with eclipse. I have downloaded the software
from:

http://java.sun.com/products/java-media/jmf/2.1.1/download.h tml

I have added the all the jars in the lib folder to the eclipse class path
by going to:

windows > java > build path > class variables > new

I tried adding just the folder but have also tried adding all the jars
separately. I made a quick test by writing a program that just imports

import javax.media.*;

.

However, it does not compile in eclipse (i get the following error):

Quote:

"Exception in thread "main" java.lang.Error: Unresolved compilation
problem:

at MediaPlayer.main(MediaPlayer.java:4)"

However, if i compile the file from command line it compiles fine. Any
ideas what i have done wrong? It must be something to do with the way i'm
setting up eclipse but cannot find out what.

Thanks

You also need to go to the project's popup and via Properties->Java
Build Path->Libraries add the libraries to be available on the build
path for that project.

As Ed said, you need to add the Classpath Variable you created to the
Build Path of your project (right-click on the project and select
Properties).
I strongly suggest you open the Help Contents and find the tutorials
under the Java Development User Guide > Getting Started section. There
is a tutorial specifically about project organization that will help you
understand how to set up projects in Eclipse. The hour or two you spend
there will save you many more hours down the road as you use Eclipse.

Feel free to post follow-up questions here if the tutorial doesn't
answer them all.

I get the following error message in eclipse for all javax.media imports.:

"Access restriction: The type Buffer is not accessible due to restriction on required library C:\Program
Files\Java\jre6\lib\ext\jmf.jar"

I added the following classpath variable under java build path"
jmf C:/Program Files/Java/JMF-2.1.1e/lib/jmf.jar

I added jmf variable to the project's build path libraries.

I am able to compile jmf code in command line.

Any idea how to get jmf to compile with eclipse?

Take the JMF jar out of your JRE lib/ext/ directory (the lib/ext
"feature" is perhaps one of the worst ideas ever implemented in the JRE,
in my opinion).
If you're project needs JMF, just include that JAR in the project's own
lib/ directory and add it to the Build Path.

Hope this helps,
Eric

If new to Eclipse, you might benefit from this tutorial on JARs, Build
Path including how to include "foreign" JARs in Eclipse:

http://www.windofkeltia.com/j2ee/jar-tutorial.html

Good luck.
