Adding tags programatically after blog entry added in Blogs portlet

Adding tags programatically after blog entry added in Blogs portlet

1. create a hook and add portal properties.

2. In portal properties write the portall property as given below:

value.object.listener.com.liferay.portlet.blogs.model.BlogsEntry=com.test.liferay.portlet.blogs.NewBlogEntryListener

    we are doing for  blog content , so we need to create listener for BlogsEntry model.

3. create the above class -NewBlogEntryListener in the package as mentioned above:

4. Write the code below:

NewBlogEntryListener.java
