Cannot change version of project facet dyanmic web module 3.0 to 2.5
<p>I saw lot of similar questions was asked for change the dynamic web module.
But still I am unable to find perfect solution. I’m very new to Java J2EE.</p>

<p>I need to import war project in to my eclipse workspace and need to deployed on local tomcat6.</p>

<p><strong>This is step i used:</strong></p>

<ol>
<li>Import war file</li>
<li>Open the Build Path in project Java  and import JRE System Libray[jdk1.6.0_45],all WebContent\WEB-INF\lib in to build path</li>
<li>In project Java Compiler set as JDK compliance as 1.6</li>
<li>Add tomcat6 server in to the eclipse servers</li>
<li>Try to set Dynamic Web Module 3.0 to 2.5 in project facets that gave me Java 1.5 or newer error. Please refer the below image for more details</li>
</ol>
