Troubleshooting
Problem
In Response Headers, it exposures the version number of the Apache Tomcat Web Server which runs on port 8080 by default. It's better to provide a way to protect the information.
Symptom
Tomcat has allowed to modify the server's attribute "server" to protect the version information.
In WebSphere Application Server Community Edition 1.1, we suggest the good practice to follow the tomcat behavior is below.
In <wasce-home>\var\config\config.xml
<module name="geronimo/tomcat/1.1/car">
<gbean name="TomcatEngine">
<attribute name="initParams">name=Geronimo</attribute>
<reference name="TomcatValveChain"/>
</gbean>
<gbean load="false" name="FirstValve"/>
<gbean load="false" name="SecondValve"/>
<gbean name="TomcatResources"/>
<gbean name="TomcatWebConnector">
<attribute name="host">0.0.0.0</attribute>
<attribute name="port">8080</attribute>
<attribute name="redirectPort">8443</attribute>
<attribute name="bufferSizeBytes">2048</attribute>
