# schemagen

Generates a schema for every name space that is referenced in your Java classes.

## Synopsis

schemagen [ options ] java-files

options

  The command-line options. See Options.

java-files

  The Java class files to be processed.

## Description

The schema generator creates a schema file for each name space referenced in your Java classes. Currently, you cannot control the name of the generated schema files. To control the schema file names, see 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. The current schema generator can process either Java source files or class files.

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

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. If the referenced files are not accessible or specified, then you get errors when you generate the schema.
