Alfresco Search Portlet for Liferay

Most developers who have worked with Alfresco and Liferay have had the problem of having to integrate both applications.

 This integration has become progressively more complex, especially since both platforms are competing for some products increasingly similar, which means that they no longer be supported. Fortunately we have the APIs to program our own applications.

Alfresco Search Portlet uses the Alfresco web services api to do searches on the repository. Similarly, we may develop several portlets for exploiting other features of Alfresco api.

Below are two scren shots of the portlet in view and edit modes:

 The portlet uses a username and password to connect to alfresco and perform a search based on permissions for that user.

Finally, note that the portlet has been tested in the following environment:

Community Liferay 5.2.3 & 6.0, Alfresco 3.2 & 3.3, JDK 1.5 +.

Creating a webscript dashlet in Alfresco

To develop a custom dashlet in Alfresco we need 3 things:

- A Webscript.
- A Jsp.
- A Freemarker template.

1.- Firstly, create a webscript with the actions that you want to show in Alfresco Dashboard. WebScripts WikiPage.

For example:
\tomcat\webapps\alfresco\WEB-INF\classes\alfresco\templates\my_webscript.ftl

2.- Create a Jsp for the dashlet in: \tomcat\webapps\alfresco\jsp\extension\dashboards\dashlets\my_webscript.jsp with this content:

3.- Add to web-client-config-custom.xml the next config:

Finally restart Alfresco and configure the dashboard to show your new dashlet.

Api JavaScript samples in Alfresco

Alfresco allows us to perform actions when an event occurs, such as content creation, modification, and so on. Here are some examples of use:

Js that sent mails:

  // create mail action
  var mail = actions.create("mail");
  mail.parameters.to = "user@mail.com";
  mail.parameters.subject = "News Letter Title";
  mail.parameters.from = "alfresco@society.com";
  mail.parameters.template = search.findNode("workspace://SpacesStore/9c74d256-ff43-4437-rio5-3098c54fbc7a");
  mail.parameters.text = "Sorry, but the news letter is not available this week due to maintenance needs. Please apologize for disturbance";
  // execute action against a document
  mail.execute(document);

Js that start and advanced pooled workflow:

  var workflow = actions.create("start-workflow");
  workflow.parameters.workflowName = "jbpm$wf:reviewpooled";
  workflow.parameters["bpm:workflowDescription"] = document.name;
  workflow.parameters["bpm:groupAssignee"] = people.getGroup("GROUP_myGroup");
  var futureDate = new Date();
  futureDate.setDate(futureDate.getDate() + 7);
  workflow.parameters["bpm:workflowDueDate"] = futureDate;
  workflow.execute(document);

Js that change the name of an inbound document:

  // change the name of this document
  document.properties.name = "Backup of " + document.properties.name;
  // add a new property string
  document.properties["cm:locale"] = mylocalenode;
  // save the property modifications
  document.save();

Expanding Alfresco JVM memory

When we launch for first time Alfresco Comunity 3.2, we get this warning:

Alfresco JVM - WARNING - maximum heap size 494.938MB is less than recommended 512MB

We have to expand the JVM memory to solve it. Go to Alfresco install home and edit the alfresco.bat/alfresco.sh file , and modify the JAVA_OPTS like that:

Linux:
export JAVA_OPTS='-Xms256m -Xmx1024m -XX:MaxPermSize=512m -server

  
Windows:
set JAVA_OPTS='-Xms256m -Xmx1024m -XX:MaxPermSize=512m -server
