Some technicalities about Tomcat.
You can unrar a war file in an external hard disk, and have Tomcat point to it.
The simpler way is to change under server.xml, change appBase=”webapps” to appBase=”J:/MyApps/”. All applications will then be hosted under that directory.
But there are other ways too, such as adding <context> a Context element.
<context docbase="J:/MyApps/MyWeb" path="/MyWeb">
</context></context>
To copy .war to Tomcat webapps after building in netbeans, add the following to build.xml:
<target name="-post-dist">
<target><copy file="${dist.war}" todir="C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps">
</copy></target></target>
Failed to start apache with service-specific error 0x0. Tomcat service log error shows “Failed creating java C:\Program Files\Java\jre1.6.0_03\bin\client\jvm.dll”. This is due to msvcr71.dll not found by Tomcat.

To setup a web server to serve .cab OTA installation for Windows Mobile application, add to web.xml:
<mime-mapping>
<extension>cab</extension>
<mime-type>application/x-cab-compressed</mime-type>
</mime-mapping>
Increase Java Heap Size
The default heap size for Tomcat is pretty small. When the memory used is more than the maximum specified, a OutOfMemoryError is frequently encountered.
A convenient way is to put this in catalina.bat:
set CATALINA_OPTS="-Xmx256m"
