The binding compiler can be launched using the appropriate
xjc shell script in the
for your platform. We also provide an Ant task to run the binding
complier - see the instructions for
using xjc with Ant.

If all else fails, you should be able to execute the
- For Solaris/Linux:
- % java -jar $JAXB_HOME/lib/jaxb-xjc.jar -help
- For Windows:
- > java -jar %JAXB_HOME%\lib\jaxb-xjc.jar -help
This is equivalent of running "xjc.sh" or "xjc.bat", and it allows you to set the JVM parameters.
- By default, the XJC binding compiler performs strict validation of the source schema before processing it. Use this option to disable strict schema validation. This does not mean that the binding compiler will not perform any validation, it simply means that it will perform less-strict validation.
- By default, the XJC binding compiler strictly enforces the rules outlined in the Compatibility chapter of the JAXB Specification. Appendix E.2 defines a set of W3C XML Schema features that are not completely supported by JAXB v1.0. In some cases, you may be allowed to use them in the "-extension" mode enabled by this switch. In the default (strict) mode, you are also limited to using only the binding customizations defined in the specification. By using the "-extension" switch, you will be allowed to use the JAXB Vendor Extensions.
- -b <file>
- Specify one or more external binding files to process. (Each binding file must have it's own "-b" switch.) The syntax of the external binding files is extremely flexible. You may have a single binding file that contains customizations for multiple schemas or you can break the customizations into multiple bindings files:
xjc schema1.xsd schema2.xsd schema3.xsd -b bindings123.xjbIn addition, the ordering of the schema files and binding files on the command line does not matter.
xjc schema1.xsd schema2.xsd schema3.xsd -b bindings1.xjb -b bindings2.xjb -b bindings3.xjb
- -d <dir>
- By default, the XJC binding compiler will generate the Java content classes in the current directory. Use this option to specify an alternate output directory. The output directory must already exist, the XJC binding compiler will not create it for you.
- -p <pkg>
- Specifying a target package via this command-line option overrides any binding customization for package name and the default package name algorithm defined in the specification.
- -httpproxy <proxy>
- Specify the HTTP/HTTPS proxy. The format is [user[:password]@]proxyHost[:proxyPort]. The old -host and -port are still supported by the RI for backwards compatibility, but they have been deprecated.
- -classpath <arg>
- Specify where to find client application class files used by the <jxb:javaType> and <xjc:superClass> customizations.
- -catalog <file>
- Specify catalog files to resolve external entity references. Supports TR9401, XCatalog, and OASIS XML Catalog format. Please read the XML Entity and URI Resolvers document or the catalog-resolver sample application.
- By default, the XJC binding compiler does not write-protect the Java source files it generates. Use this option to force the XJC binding compiler to mark the generated Java sources read-only.
- Supress the generation of package level annotations into **/package-info.java. Using this switch causes the generated code to internalize those annotations into the other generated classes.
- treat input schemas as W3C XML Schema (default). If you do not specify this switch, your input schemas will be treated as W3C XML Schema.
- Treat input schemas as RELAX NG (experimental, unsupported). Support for RELAX NG schemas is provided as a JAXB Vendor Extension.
- Treat input schemas as RELAX NG compact syntax(experimental, unsupported). Support for RELAX NG schemas is provided as a JAXB Vendor Extension.
- Treat input schemas as XML DTD (experimental, unsupported). Support for RELAX NG schemas is provided as a JAXB Vendor Extension.
- Treat input as WSDL and compile schemas inside it (experimental,unsupported).
- Suppress compiler output, such as progress information and warnings..
- Be extra verbose, such as printing informational messages or displaying stack traces upon some errors..
- Display a brief summary of the compiler switches.
- Display the compiler version information.
- <schema file/URL/dir>
- Specify one or more schema files to compile. If you specify a directory, then xjc will scan it for all schema files and compile them.
- -host & -port
- These options have been deprecated and replaced with the -httpproxy option. For backwards compatibility, we will continue to support these options, but they will no longer be documented and may be removed from future releases.
- Since the JAXB 2.0 specification has defined a portable runtime, it is no longer necessary for the JAXB RI to generate **/impl/runtime packages. Therefore, this switch is obsolete and has been removed.
- The -source compatibility switch was introduced in the first JAXB 2.0 Early Access release. We have decided to remove this switch from future releases of JAXB 2.0. If you need to generate 1.0.x code, please use an installation of the 1.0.x codebase.
- -Xlocator & -Xsync-methods
- These switches have been disabled for now. We plan on releasing this functionality as a separate download in the future.
In general, it is safest to compile all related schemas as a single unit with the same binding compiler switches.
Please keep the following list of restrictions in mind when running xjc. Most of these issues only apply when compiling multiple schemas with multiple invocations of xjc.
