NAME
xjc - Java XML Binding Compiler
SYNOPSIS
xjc [ -options ] <schema_file/URL/dir>... [ -b <bindinfo> ]...
PARAMETERS
options Command-line options.
<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.
<bindinfo> External binding file to process.
OPTIONS
-nv 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 com-
piler will not perform any validation, it simply means that it will
perform less-strict validation.
-extension
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 bind-
ing file must have its own "-b" switch.) The syntax of the exter-
nal 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.xjb
xjc schema1.xsd schema2.xsd schema3.xsd -b bindings1.xjb -b bind-
ings2.xjb -b bindings3.xjb
In addition, the ordering of the schema files and binding files on
the command line does not matter.
-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]@]prox-
yHost[:proxyPort]. The old -host and -port are still supported by
the RI for backwards compatibility, but they have been deprecated.
Note that the password specified with this option is an argument
that is visible to other users who use the top command, for exam-
ple. For greater security, use -httpproxyfile, below.
-httpproxyfile <file>
Specify the HTTP/HTTPS proxy using a file. Same format as above,
but the password specified in the file is not visible to other
users.
-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. Sup-
ports TR9401, XCatalog, and OASIS XML Catalog format. Please read
the XML Entity and URI Resolvers document or the catalog-resolver
sample application.
-readOnly
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.
-npa
Supress the generation of package level annotations into **/pack-
age-info.java. Using this switch causes the generated code to
internalize those annotations into the other generated classes.
-xmlschema
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.
-relaxng
Treat input schemas as RELAX NG (experimental, unsupported). Sup-
port for RELAX NG schemas is provided as a JAXB Vendor Extension.
-relaxng-compact
Treat input schemas as RELAX NG compact syntax(experimental, unsup-
ported). Support for RELAX NG schemas is provided as a JAXB Vendor
Extension.
-dtd
Treat input schemas as XML DTD (experimental, unsupported). Support
for RELAX NG schemas is provided as a JAXB Vendor Extension.
-wsdl
Treat input as WSDL and compile schemas inside it (experimen-
tal,unsupported).
-quiet
Suppress compiler output, such as progress information and warn-
ings.
-verbose
Be extra verbose, such as printing informational messages or dis-
playing stack traces upon some errors.
-help
Display a brief summary of the compiler switches.
-version
Display the compiler version information.
Summary of Deprecated and Removed Command Line Options
-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.
-use-runtime
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.
-source
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.
Compiler Restrictions
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.
o To compile multiple schemas at the same time, keep the following
precedence rules for the target Java package name in mind:
1. The "-p" command line option takes the highest precedence.
2. <jaxb:package> customization
3. If targetNamespace is declared, apply targetNamespace -> Java
package name algorithm defined in the specification.
4. If no targetNamespace is declared, use a hardcoded package
named "generated".
o It is not legal to have more than one jaxb:schemaBindings> per
namespace, so it is impossible to have two schemas in the same
target namespace compiled into different Java packages.
o All schemas being compiled into the same Java package must be sub-
mitted to the XJC binding compiler at the same time - they cannot
be compiled independently and work as expected.
o Element substitution groups spread across multiple schema files
must be compiled at the same time.
