Constructor Detail

MyLeadCreateImpl

public MyLeadCreateImpl(org.w3c.dom.Element element)
                 throws uk.org.ogsadai.common.exception.engine.activity.ActivityUserException,
                        uk.org.ogsadai.common.exception.engine.activity.ActivitySystemException
Constructor

Method Detail

getResult

protected boolean getResult()
                     throws java.sql.SQLException,
                            uk.org.ogsadai.common.exception.engine.activity.ActivitySystemException,
                            uk.org.ogsadai.common.exception.engine.activity.ActivityUserException
This method does the actual processing of each leadCreate node included in the perform document, processing them in the order in which they were included in the perform document. If it encounters any error in executing or in the data (e.g., the user does not exist) then an OGSA-DAI ActivityUserException is thrown and the processBlock method outputs the error message returned to the user. If the creates are successful, this method adds the metadata response with the ReturnType indicating success.

Overrides:
getResult in class uk.org.ogsadai.activity.sql.SQLActivity
Returns:
boolean indicating if getResult completed. Although the return value is not used in this activity's process block method, it has to return a boolean since this method returns a boolean in the SQLActivity as defined in OGSA-DAI.
Throws:
SQLException, - ActivitySystemException, ActivityUserException
java.sql.SQLException
uk.org.ogsadai.common.exception.engine.activity.ActivitySystemException
uk.org.ogsadai.common.exception.engine.activity.ActivityUserException

processBlock

public void processBlock()
No Exceptions are thrown since they will be flagged as a status flag with the activity and the output stream will be closed On error endProcessing is called and the ERROR status is set.

Specified by:
processBlock in class uk.org.ogsadai.engine.Activity
