Unable to use custom tag when running applicaiton in war





------- Additional Comments From jian.cai@sun.com  2002-11-19 01:47 -------
Here is the simple way to reproduce the bug:

In the server.xml add the following <Context..> entry inside the <Host
name="localhost" ...> element

like:
 
<Host name="localhost" debug="0" appBase="webapps"
       unpackWARs="true" autoDeploy="true">
......

        <Context className="org.apache.catalina.core.StandardContext"
cachingAllowed="true"
charsetMapperClass="org.apache.catalina.util.CharsetMapper" cookies="true"
crossContext="false" debug="0" displayName="JSPSample"
docBase="jsp-examples2.war"
mapperClass="org.apache.catalina.core.StandardContextMapper" override="true"
path="/jsp-examples2" privileged="false" reloadable="false" useNaming="true"
wrapperClass="org.apache.catalina.core.StandardWrapper">
        </Context>


	the context points to a jsp-examples2.war (just a copy of the jsp-examples.war)
as docBase. When the containter starts, there will be no jsp-examples2 directory
created. The webapplication can be access in http://localhost:8080/jsp-examples2/

but when click the links of the samples, there will be exception:

Such as:

java.lang.NullPointerException
