2. Add the serialization element to the global element as follows:

   <infinispan>
     <global>
       <serialization />
     </global>
   </infinispan>

   Copy to Clipboard Toggle word wrap
3. Add the advancedExternalizer element to add information about the new advanced externalizer as follows:

   <infinispan>
     <global>
       <serialization>
         <advancedExternalizer />
       </serialization>
     </global>
   </infinispan>

   Copy to Clipboard Toggle word wrap
4. Define the externalizer ID using the id attribute as follows:

   <infinispan>
     <global>
       <serialization>
         <advancedExternalizers>
          <advancedExternalizer id="$ID" />
         </advancedExternalizers>
       </serialization>
     </global>
   </infinispan>

   Copy to Clipboard Toggle word wrap
   Ensure that the selected ID is not from the range of IDs reserved for other modules.
5. Define the externalizer class using the externalizerClass attribute as follows:

   <infinispan>
     <global>
       <serialization>
         <advancedExternalizers>
          <advancedExternalizer id="$ID" externalizerClass="org.infinispan.marshall.AdvancedExternalizerTest$IdViaConfigObj$Externalizer"/>
          </advancedExternalizers>
       </serialization>    
     </global>
   </infinispan>
