Liferay Custom Portlet To Change Password

---

In this article we will create a custom portlet to change liferay password. Sometimes we need our own functionality to change liferay credentials. For example consider you working on user management where you want user to update their own password. This article is a quick recipe to build our own custom portlet to change password effectively.

AuthType:3 Ways to Login Liferay

Source Code Download:

The source code of the portlet is attached at the bottom of this article. You can download the portlet and deploy in your liferay server. After deployment the portlet will look like this

Liferay API to change password:

In liferay source code open the file UserLocalServiceImpl.java. Below is the method we can use for changing password of the logged in user

[example title=”Method Signature”]
public long authenticateForBasic(
long companyId, String authType, String login, String password)
throws PortalException, SystemException {
[/example]

The explanation of the method is explained below

 

On the basis of the above method below is the portlet class developed. Read the comments carefully in the code.
