Hi All,

I would like to use the org.apache.catalina.filters.RemoteAddrFilter
filter as part of my web.xml settings. I am just curious to know which
jar file has that class.

Please let me know
Thanks,
Zari

You can find which paths are included in which jars from the build.xml
(though it takes a bit of knowledge about what ant is doing), or a
quick grep on the jar files in lib:

$ grep RemoteAddrFilter lib/*
Binary file lib/catalina.jar matches

Thanks ... I am using windows machine ... I tried another editor did
not work so I switched JAD java decompiler... I just needed to open
the core tomcat zip file and then I could see and search all classes
in it.

I like this little gem:

$ for jar in $CATALINA_HOME/lib/*.jar ;
do echo "$jar" ;
unzip -v "$jar" | grep RemoteAddrFilter" ;
done

This will print a list of all the JARs (I'm sure there is a way to
suppress the ones that don't match) and then, underneath the one that
matches, you'll see the file:

/apache-tomcat-8.0.46/lib/annotations-api.jar
/apache-tomcat-8.0.46/lib/catalina-ant.jar
/apache-tomcat-8.0.46/lib/catalina-ha.jar
/apache-tomcat-8.0.46/lib/catalina-storeconfig.jar
/apache-tomcat-8.0.46/lib/catalina-tribes.jar
/apache-tomcat-8.0.46/lib/catalina.jar
1935 Defl:N 740 62% 08-10-2017 13:11 cf250a0f
org/apache/catalina/filters/RemoteAddrFilter.class
/apache-tomcat-8.0.46/lib/ecj-4.6.3.jar
/apache-tomcat-8.0.46/lib/el-api.jar
...

So you can see that catalina.jar contains the file.

I like this better just in case the filename has been mangled in some
way inside of the JAR file (even though it shouldn't be).
