Because you put the update outside the transaction.  Move it inside.

If you want to use BaseServlet, you will want to subclass it.  Examples of
how this is done can be found in

$ find core/src/ cms/src/ -name \*.java | \
  xargs grep BaseServlet | grep extends | cut -d : -f 1
core/src/com/arsdigita/versioning/VersioningServlet.java
core/src/com/arsdigita/web/BaseApplicationServlet.java
core/src/com/arsdigita/web/BaseJSP.java
core/src/com/arsdigita/web/BaseServlet.java
core/src/com/arsdigita/web/DispatcherServlet.java
core/src/com/arsdigita/web/LegacyInitializerServlet.java
core/src/com/arsdigita/web/OIDRedirectServlet.java
core/src/com/arsdigita/web/ResourceServlet.java
cms/src/com/arsdigita/cms/dispatcher/ContentTypeXSLServlet.java
cms/src/com/arsdigita/cms/dispatcher/ContentItemXSLServlet.java


If you don't want to subclass BaseServlet, then your second best bet is to
copy and paste some of the transaction-handling code from BaseServlet
into your own servlet.
