 +====== Dynamic Language Support in Spring ======
 +
 +Spring [[http://static.springsource.org/spring/docs/2.5.x/reference/dynamic-language.html|supports the use of scripts]]. In other words, create a bean in Groovy, Jruby and call it as a normal bean from our application. 
 +
 +However, when I tried to use this feature of Spring, even with the last up-to-date version (3.1.1), many errors arise, due to the lack of proper libraries. 
 +
 +Many forums recall to the use of Maven to download properly these missing jars, but I don't want to use it. Other forums give solutions that are not solutions at all, so I've decided to collect these notes. 
 +
 +===== java.lang.ClassNotFoundException: org.aopalliance.aop.Advice =====
 +
 +You can find this missing class in this sourceforge project: 
 +
 +[[http://sourceforge.net/projects/aopalliance]]
 +
 +However **the 'default' file for download is an incorrect one:** an alpha version that doesn't work. [[http://sourceforge.net/projects/aopalliance/files/aopalliance/1.0/|Look into the files section]] to get the latest version.
 +
 +===== java.lang.ClassNotFoundException: org.codehaus.groovy.control.CompilationFailedException =====
 +
 +You have to download [[http://groovy.codehaus.org|Groovy]]. 
 +
 +I made the following: 
 +
 +  - Download Groovy (binary release)
 +  - Unzip the file and locate the "embedable" directory in it: it contains a single jar file with all the groovy
 +  - Add it to your project
 +
 +===== Location is incorrect also =====
 +
 +Here is my working example of my --still very simple-- groovy bean: 
 +
 +<code xml>
 + <lang:groovy id="customField"
 + script-source="classpath:com/supermanhamuerto/nestor/actions/CustomFieldImpl.groovy"
 + scope="prototype">
 + <lang:property name="message" value="Hello from groovy!!!!"/>
 + </lang:groovy>
 +</code>
 +
 +If you have put your script into the package "com.supermanhamuerto.nestor.actions", you must specify the complete path into the ''script-source'' attribute.
