Weblogic.descriptor.DescriptorException: Unmarshaller failed

Question

Caused by: com.bea.xml.XmlException: weblogic.descriptor.BeanAlreadyExistsException: Bean already exists: "weblogic.j2ee.descriptor.ParamValueBeanImpl@1e184cf(/ContextParams)"
I know that Thread was posted already but what I read did not really fix the issue. (I have unzipped the Oracle\Middleware\wlserver_10.3\server\lib\wseeclient.zip).
My JSP/Java app was working fine until I created another ADF app in the same JDeveloper studio and run the 2 apps concurrently.
Also I noticed the web.xml of the first app is now empty:
<?xml version = '1.0' encoding = 'UTF-8'?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
version="2.5">
<context-param>
<param-name></param-name>
<param-value></param-value>

</context-param>
<listener>
<listener-class></listener-class>
</listener>
<listener>
<listener-class></listener-class>
</listener>
</web-app>
Is there a Guru in this universe that knows what is going on here?

Marc,
if you already have posted this problem it would be helpful if you link to the old thread. This is especially true as you don't give any specifics about your environment and we start all over with questions already asked.
Please always mention your jdev version and any other helpful information about your environment.
The error you get points to a duplicate bean name (e.g. app 1 and app 2 are using the same name).
