Quick Start (EJB mode): Retrieving task information using the Java API

The following Java code example retrieves all tasks that are based on a process named MortgageLoan - Prebuilt. The status of each returned task is checked to ensure that it is a completed task. Information such as the name of the user who completed the task and the date that the task was completed is retrieved and displayed.

    * This Java Quick Start uses the following JAR files 
    * 1. adobe-taskmanager-client.jar 
    * 2. adobe-livecycle-client.jar 
    * 3. adobe-usermanager-client.jar 
    * 4. adobe-utilities.jar 
    * 5. jbossall-client.jar (use a different JAR file if the LiveCycle server is not deployed 
    * on JBoss) 
    * 6. commons-code-1.3.jar 
    * 7. adobe-workflow-client-sdk.jar 
    * 8. jacorb.jar (use a different JAR file if the LiveCycle server is not deployed on JBoss) 
    * 9. jnp-client.jar (use a different JAR file if the LiveCycle server is not deployed on JBoss) 
    *  The JBoss files must be kept in the jboss\client folder. You can copy the client folder to  
    *  your local development environment and then include the 3 JBoss JAR files in your class path 
    *  These JAR files are located in the following path: 
    * <install directory>/sdk/client-libs/common 
    * The adobe-utilities.jar file is located in the following path: 
    * <install directory>/sdk/client-libs/jboss 
    * The jbossall-client.jar file is located in the following path: 
    * <install directory>/jboss/client 
    * If you want to invoke a remote LiveCycle server instance and there is a 
    * firewall between the client application and the server, then it is  
    * recommended that you use the SOAP mode. When using the SOAP mode,  
    * you have to include additional JAR files located in the following  
    * path 
    * <install directory>/sdk/client-libs/thirdparty 
    * For information about the SOAP  
    * mode and the additional JAR files that need to be included,  
    * see "Setting connection properties" in Programming  
    * with LiveCycle
