Refreshing JSP file for an exploded WAR without undeploying the WAR - 7210

Question

The weblogic.Deployer utility with -activate option does redeploy my application. How do I prevent redeployment while refreshing. I'm using Weblogic 7.0.0.0.
          Thanks

Thanks mbg for your response.
          Our production environment does not support the option a. We use the
          option b approach.
          My config.xml looks like this for the webapplication
          <Application Deployed="true" Name="oas"
          Path="/tmp/senthil/oas3.7.1.5"
          StagedTargets="DOAS_MT_021_20501" TwoPhase="true">
          <WebAppComponent Name="oas" Targets="DOAS_MT_CLUSTER_1"
          URI="oas"/>
          </Application>
          I performed the following steps..
          1) Modified the following jsp file on the admin.
          /tmp/senthil/oas3.7.1.5/oas/customercare/contactus.jsp
          2) Ran the following command on the admin
          java weblogic.Deployer -adminurl t3://n.n.n.n:20501 -user system
          -password weblogic -name oas -activate customercare/contactus.jsp
          after running the command,
          I was able to identify the corresponding jsp file immediately updated
          on the managed instance under the stage folder. But the class file on
          the stage folder was not updated and neither the class file on the
          .wlnotdelete folder. I was using the pagecheckseconds on the
          weblogic.xml as -1.
          I stopped both the admin and manage, modified the pagecheckseconds to
          1 Hour and when I performed same steps as before, I was able to see
          the jsp file updated and also getting compiled (when accessed) and
          serving the updated content. Also the user session was kept intact.
          i.e. no interruption to the session. This was what I was expecting
          for. The strange thing is, it didn't wait for one hour to compile. It
          was compiling immediately when I accessed the modified jsp file. I'm
          not sure whether it would behave the same way if I put that value as 1
          day or some very big +ve value.
          I'm not sure whether I'm doing the right way. i.e. changing the
          pagecheckseconds to ve value. Also I'm not sure whether the ve value
          for the pagecheckseconds would create impact on performance.
          Thanks for your time.
