问题 Does the JSR 286 spec require the presence of a web.xml file in WARs containing portlets? At first, I thought so but then I created a portlet without a web.xml , deployed it in Liferay and it worked flawlessly. So is it an extension (or a bug) of Liferay, or is it not necessary to have such a file? 回答1: As Olaf rightly said portlet is nothing but a web application. Liferay has a listener that gets triggered when the portlet auto deploys. It explodes the war and adds web.xml and the content

问题 I have already posted one question on the same issue. But I'm not able to solve my issue and not able to move forward in my task. I have created a editable portlet where in the configuration page I am showing he dynamic questions which are fetching form the database. So for the same reason I am iterating my array list and creating the input fields dynamically as follows, Iterator<String> itr = al.iterator(); while(itr.hasNext()) { String columnVal = itr.next(); columnVal = columnVal.trim()

问题 I am configuring Liferay with my organization LDAP. 1.While configuring LDAP, I specify "ldap.security.principal" and "ldap.security.credentials" as my user id and password to authenticate against LDAP and test connection succeeds. Are these mandatory attributes? As in production ,I will not be able to specify my own credentials in portal-ext.properties. Do I need separate user created in LDAP to specify in portal-ext for production? I unfortunately do not have control over configuring LDAP

问题 I am coding an application using Liferay 7 and OSGi modules. I need to create a custom taglib available across all modules (portlets), but I have litteraly no idea where to start. Do you have any idea? Should I store the taglib definition, classes and JSPs in an OSGi modules? And if not, where, and how can I reference it from a portlet module? Thank you very much 回答1: In most cases you should be able to deliver a taglib completely within an OSGi module. You can find several examples in

问题 I am using Liferay with Apache Tomcat and hsql. I need to locate the database file that is used. According to hsql documentation there should be a file lportal.data in the directory data/hsql, but there isn't one. 回答1: The hibernate database consists of 4 files. The .script file contains the data as SQL, the .log that last actions that took place, the .properties the configuration and the .lck is the db lockfile. These are the database, hsql has nothing like one big .data file. All other

问题 My portal is able to successfully authenticate with LDAP server (Active Directory) but due to liferay scheduler importing users after some interval, my system performance is degrading. I can see high memory and CPU usage for JAVA and MySql process. As Active directory is not configured properly, I can see many exceptions related to users not imported due to some issue in log files. As per log file I have added few filters in LDAP query to filter relevant entities (users). I am using following
