Create static headers in Apache Tomcat just by editing web.xml.
This project came about when trying to debug a CORS problem. Tomcat has a built in CORS filter org.apache.catalina.filters.CorsFilter but this filter has lots of internal logic that masked the problem I was trying to debug. A stack overflow question suggested building a new filter that just returned static values. I found having to write a java class, compile into byte code, and then package into a jar file a large hassel just to test a couple of headers. As a result, I created this generic filter that allows for the easy creation of headers by simply editing the web.xml file.
- Install release jar in CATALINA_HOME/lib
- Add filter to CATALINA_HOME/conf/web.xml
<filter>
<filter-name>StaticHeadersFilter</filter-name>
<filter-class>StaticHeaders</filter-class>
<init-param>
<param-name>hello</param-name>
<param-value>world</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>StaticHeadersFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
- restart apache tomcat
- test headers
curl -XGET -I 'http://localhost:8080'
- Set CATALINA_HOME env
- run
make.sh
