Use java to connect to Webservice Magento API SOAP v1?

Question

On the official website, http://www.magentocommerce.com/api/soap/introduction.html, has a quote that says that java is more compatible when using Soap v2:

As of v1.3, you may also use the following URL to access the Magento API v2, which has been Added to improve Compatibility with Java and . NET:

I tried using v1 with java, but when compiling in the terminal this project magento-java using Maven (mvn install, or mvn package) me returns these two errors:

[ERROR] /magento-java/src/main/java/com/magi/magento/service/BaseService.java:[27,34] cannot find symbol

[ERROR] /magento-java/src/main/java/com/magi/magento/service/OrderService.java:[112,44] incompatible types

I saw that you have a second option to use java to connect with the web service which is the magja: http://code.google.com/p/magja/

What is recommended to integrate in java? In php it’s easy, but java complicates the situation.

Another thing, I want to use in v1 anyway (/pastaMagento/index.php/api/soap/?wsdl) to connect with my WS using java, which is the best way and how should I do this?
