<<<<<<<<<<
Symptoms:
We have password type global variables. The ear file is built successfully but we failed to export XML from ear through Appmanage.

Cause:
In the defaultVars.substvar file, check if any Password type GV (global variable) has its value as: 
    <value/>

Example:  
  >>>>>>>>>>>>>>>
          <globalVariable>
            <name>New_Variable_1</name>
            <value/>
            <type>Password</type>
            <deploymentSettable>true</deploymentSettable>
            <serviceSettable>false</serviceSettable>
            <description/>
            <constraint/>
            <modTime>1290161485235</modTime>
        </globalVariable>
  <<<<<<<<<<<<<<<

Resetting the value of the Password type GV should resolve this issue. If you need a password to be null, enter and then delete the value. After modification, even for the null password, the value in defaultVars.substvar file has the value.

Example:
  >>>>>>>>>>>>>>>>
          <globalVariable>
            <name>password</name>
            <value>#!RzTjJmlw1awTwKAils1BwA==</value>
            <type>Password</type>
            <deploymentSettable>true</deploymentSettable>
            <serviceSettable>false</serviceSettable>
            <description/>
            <constraint/>
            <modTime>1290159302052</modTime>
        </globalVariable>
