1. Using Spring to get the service for your class (e.g. YourAppClass) (recommended)
   1. Add the ToolManager bean to the bean for YourAppClass

      Code Block
      xml xml
      <bean id="org.sakaiproject.yourapp.logic.YourAppClass" class="org.sakaiproject.yourapp.logic.impl.YourAppClassImpl"> <property name="toolManager" ref="org.sakaiproject.tool.api.ToolManager" /> </bean>

   2. Add a variable and setter to YourAppClass to use the service in like so:

      Code Block
      java java
      private ToolManager toolManager; public void setToolManager(ToolManager toolManager) { this.toolManager = toolManager; }

2. Using the cover Component Manager to get the service
   • Note: This is not the recommended method, you should be using Spring to inject the service
   1. Setup a variable to hold the instance from the cover Use the CM cover to get the service

      Code Block
      java java
      import org.sakaiproject.component.cover.ComponentManager; import org.sakaiproject.tool.api.ToolManager; ... private ToolManager toolManager;

      Get access to the service using the cover

      Code Block
      java	java	... toolManager = (ToolManager) org.sakaiproject.tool.cover.ComponentManager.get(ToolManager.getInstance(class);

Getting the current

...

context for the current

...

request (current user most likely)

• Use this to tie data to a specific use of a tool in an area (probably a site or a section)

1. Use the service variable to access the service and get the current Placement context

   Code Block
   java java
   Site site = null; try { siteString currentContext = siteService.getSite(toolManager.getCurrentPlacement().getContext()); } catch (Exception e) { // assume we are not in a site then throw new RuntimeException("Cannot get the current site placement"); } return site.getId(); );

   • Note: The current context is probably the current site Id but do not depend on this
   • Note: If you just need the current Placement reference (which may be the current site reference which is probably the current site Id) then you can do this:

     Code Block
     java java
     StringPlacement currentPlacementRefcurrentPlacement = toolManager.getCurrentPlacement().getContext();
