Trying to make a Java EE/JPA application run, but I keep getting errors from Observer

Question

I set up JPA with a MySQL data source, after hours of driver problems, this finally works.

Now, when I try to deploy it, I keep getting weld errors about Observer. I'm not sure what this means, I couldn't find anything about it.

I would be grateful if anybody can help me out.

Here's the error:

[2015-11-15 03:53:06,923] Artifact Artists:ear exploded: Error during artifact deployment. See server log for details.

NoSuchMethodError is very clear ... you have inconsistent jars ... in this case Weld. So find a version that has that method — Neil Stockton, Nov 15 '15 at 15:00
@NeilStockton I found a weld-core version that has this method. http://grepcode.com/file/repo1.maven.org/maven2/org.jboss.weld/weld-core/2.1.0.Final/org/jboss/weld/context/AbstractBoundContext.java?av=f#26 2.1.0.Final. I added this one into my maven pom file and removed the old jar. It still doesn't work unfortunately.. — Kevin Van Ryckegem, Nov 15 '15 at 15:10
so if it complains about NoSuchMethodError then it is NOT finding the new jar and has some other jar. — Neil Stockton, Nov 15 '15 at 15:22

Thanks to Neil Stockton for the help.

I removed the weld jars from my library and added the weld-core in my maven pom file.

Everything works after removing the weld jar files!
