问题 I'm working on an application that shows information stored on a Liferay database. For doing that I made a web service, using Java, that reads data from the database. All queries are going well but I need a login section. The issue is that the password is encrypted and I don't know how to compare the password given by the user and the passwords I have in the database, that are encrypted. EDIT : passwords.encryption.algorithm has the default value: PBKDF2WithHmacSHA1/160/128000 Any suggestion?

问题 Working on a MVCPortlet (Liferay 6.2) . Is there any reason why this ajax call works on a regular jsp of my portlet, but does not work on the config page of the portlet (the jsp that opens when you click top right corner and then configuration and option).

When a portlet, deployed on the Same Tomcat , calls the same

问题 I am working with Liferay 6.0 on JBoss 5.1.1, Windows 8 is the OS.

However, I'm unable to configure it in the portal-ext.properties file as explained here. When I log into the Liferay control panel, and look under Portal Administration -> Portal

问题 (Old question bump) I'm doing some tests on Liferay. For this, I'm following the MVC tutorial, and got stuck in the services stuff. I created a simple entity for testing purposes, "Miclase": public class Miclase { int num1; String string1; } Pretty simple, huh. Well, after this, I started the service builder and created a file like this, with the Overview pane: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE service-builder PUBLIC "-//Liferay//DTD Service Builder 6.2.0//EN" "http://www

问题 I am using hibernate for my application. Sometimes hibernate generates duplicate ID and the strategy i have used is increment which does max(ID) from table and adds one. I have no clue why it happens and it happens all of sudden and after that all the subsequent requests for that table insert operations fail. the workaround for this is to restart the tomact server. here are the details of application 1. 3 applications deployed on liferay-tomcat.each has its own abstraction-impls.jar.This JAR
