💖 schemagen(1) 💖

okay so this is schemagen, one of the Java Web Services Tools, and bestie it literally does one thing and does it slay: it generates a schema for every name space that is referenced in your Java classes. periodt. ✨

🌸 NAME 🌸

schemagen — generates a schema for every name space that is referenced in your Java classes. no cap, that's the whole job description. 🫶

🎀 SYNOPSIS 🎀

schemagen [ options ] java-files

• options — the command-line options, obvi. peep the OPTIONS section below. 👀
• java-files — the Java class files that are gonna get processed. the main characters, fr.

🦋 DESCRIPTION 🦋

so the schema generator creates a schema file for each name space referenced in your Java classes. and here's the tea: currently you cannot control the name of the generated schema files. like, at all. the generator picks and you deal with it. 🙈

if you do wanna control the schema file names, go look at Using SchemaGen with Ant at:

http://jaxb.java.net/nonav/2.2.3u1/docs/schemagenTask.html

start the schema generator with the appropriate schemagen shell script in the bin directory for your platform. lowkey convenient. the current schema generator can process either Java source files or class files — flexible queen. 💅

schemagen.sh Foo.java Bar.java ...
Note: Writing schema1.xsd

so you run it like that and it's just like "noted, writing schema1.xsd" and you're like okay werk. 💖

now, important part, don't skip this: if your java files reference other classes, then those classes must be accessible on your system CLASSPATH environment variable, or they need to be specified in the schemagen command line with the class path options. see OPTIONS below bestie. and if the referenced files are not accessible or specified, then you get errors when you generate the schema. it's giving chaos, it's giving "why is nothing working", and it's entirely avoidable. 😭

✨ OPTIONS ✨

• -d path — the location where the schemagen command places processor-generated and javac-generated class files. 📁
• -cp path — the location where the schemagen command places user-specified files. 📁
• -classpath path — the location where the schemagen command places user-specified files. same energy as -cp, iconic twins. 👯
• -encoding encoding — specifies the encoding to use for apt or javac command invocations. 🌈
• -episode file — generates an episode file for separate compilation. 🎬
• -version — displays release information. know your era. 👑
• -help — displays a help message. when in doubt, ask for help, it's not embarrassing it's self-care. 🫶
