Check if you can login to the database using user/password you provided and create a table in the liferay database.

ya it is working fine for some portlet but not responding for some other portlets

i created users and details of user information is getting stored perfectly in user_ table

[Hitoshi Ozawa，修改在11 年前。]

In which portlets are it working and for which is it not working?

java.sql.SQLException: Access denied for user 'lportal'@'localhost' (using password: YES)

This implies the user you're using to access mysql database does not have proper privilege.

As per the log issue is with your credentials only

Thanks in advance

problem occur because your credential..check again the user name and password, or if using custom portlet maybe your ext-spring?

Hi I'm also getting the same error. plz help me regarding this.

This is a 3 year old zombie thread that you've just brought back to life.

I doubt that you are having the same problem that folks 3 years ago were having anyway. Different versions and all. Maybe your problem resembles this, but that doesn't mean it's the same.
