Console WAR deployment editor tool damage my web.xml file

Question

I put many servlet and servlet-mapping items in web.xml file. When I deployed my
web app into weblogic 7.0 SP1 server, I use the console to open the deployment
description, and change some parameters for the servlet. After I clicked the persist
button, the web.xml file was changed, but some servlet and servlet-mapping items
was removed unexpected.
Why?
When I start the server in Development mode, this error occured rather often.
In the product mode, this error occured a few times.
My operation steps:
1. undeploy the original app from console
2. copy the new war file to the applications directory, overwrite the old one
3. use the console to open the deployment description, make the changes
4. persist the changes
5. re-deploy the web app
Please give the solution as soon as possible

Answer 1

The tag
<target name="deploy" depends="clover-yes, clover-no">...is never closed.
close that tag:
<target name="deploy" depends="clover-yes, clover-no">
     <javac srcdir="${src.dir}" destdir="${classes.dir}" classpath="${libs}" debug="off" optimize="on" deprecation="on" compiler="${compiler}">
          <include name="org/apache/commons/fileupload/**/*.java" />
          <include name="com/portalbook/portlets/**/*.java" />
          <include name="com/portalbook/portlets/content/**/*.java" />
     </javac>
</target>Second error is that the depends in there (clover-yes, clover-no) are not existing as targets in your xml.
