.SH NAME    

xjc \- Compiles an XML schema file into fully annotated Java classes\&.

.SH SYNOPSIS    

.sp     

.nf     

\fBxjc\fR [ \fIoptions\fR ] \fBschema\fR \fIfile/URL/dir/jar\fR \&.\&.\&. [\fB\-b\fR \fIbindinfo\fR ] \&.\&.\&.

.fi     

.sp     

.TP     

\fIoptions\fR

The command-line options\&. See Options\&.

.TP     

schema \fIfile/URL/dir/jar \&.\&.\&.\fR

The location of the XML schema file\&. If \f3dir\fR is specified, then all schema files in it are compiled\&. If \f3jar\fR is specified, then the \f3/META-INF/sun-jaxb\&.episode\fR binding file is compiled\&.

.TP

-b \fIbindinfo\fR

The location of the bindings files\&.

.SH DESCRIPTION    

Start the binding compiler with the appropriate \f3xjc\fR shell script in the bin directory for your platform\&. There is also an Ant task to run the binding complier\&. See Using the XJC with Ant at http://jaxb\&.java\&.net/nonav/2\&.1\&.3/docs/xjcTask\&.html

.SH OPTIONS    

.TP 0.2i    

\(bu

See also Nonstandard Options

.TP 0.2i    

\(bu

See also Deprecated and Removed Options

.TP

-nv

.br

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, but means that it will perform a less-strict validation\&.

.TP

-extension

.br

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 \f3-extension\fR mode enabled by this switch\&. In the default (strict) mode, you are also limited to using only the binding customization defined in the specification\&. By using the \f3-extension\fR switch, you will be allowed to use the JAXB Vendor Extensions\&.

.TP

-b \fIfile\fR

.br

Specifies one or more external binding files to process\&. Each binding file must have its own \f3-b\fR switch\&. The syntax of the external binding files is flexible\&. You can have a single binding file that contains customization for multiple schemas or you can break the customization into multiple bindings files: \f3xjc schema1\&.xsd schema2\&.xsd schema3\&.xsd -b bindings123\&.xjb\fR\f3xjc schema1\&.xsd schema2\&.xsd schema3\&.xsd -b bindings1\&.xjb -b bindings2\&.xjb -b bindings3\&.xjb\fR\&. In addition, the ordering of the schema files and binding files on the command line does not matter\&.

.TP

-d \fIdir\fR

.br

By default, the XJC binding compiler generates 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 does not create it for you\&.

.TP

-p \fIpkg\fR

.br

When you specify a target package with this command-line option, it overrides any binding customization for the package name and the default package name algorithm defined in the specification\&.

.TP

-httpproxy \fIproxy\fR

.br

Specifies the HTTP or HTTPS proxy in the format \fI[user[:password]@]proxyHost[:proxyPort]\fR\&. The old \f3-host\fR and \f3-port\fR options are still supported by the RI for backward compatibility, but they were deprecated\&. The password specified with this option is an argument that is visible to other users who use the top command\&. For greater security, use the \f3-httpproxyfile\fR option\&.

.TP

-httpproxyfile file

.br

Specifies the HTTP or HTTPS proxy with a file\&. The same format as the \f3-httpproxy\fR option, but the password specified in the file is not visible to other users\&.

.TP

-classpath arg

.br

Specifies where to find client application class files used by the \fIjxb:javaType\fR and xjc:\fIsuperClass\fR customization\&.

.TP

-catalog file

Specifies catalog files to resolve external entity references\&. Supports the TR9401, XCatalog, and OASIS XML Catalog formats\&. See XML Entity and URI Resolvers at http://xerces\&.apache\&.org/xml-commons/components/resolver/resolver-article\&.html

.TP

-readOnly

.br

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 as read-only\&.

.TP

-npa

.br

Suppresses the generation of package level annotations into \f3**/package-info\&.java\fR\&. Using this switch causes the generated code to internalize those annotations into the other generated classes\&.

.TP

-no-header

.br

Suppresses the generation of a file header comment that includes some note and time stamp\&. Using this makes the generated code more compatible with the \f3diff\fR command\&.

.TP

-target 2\&.0

.br

Avoids generating code that relies on any JAXB 2\&.1 features\&. This will allow the generated code to run with JAXB 2\&.0 runtime environment (such as Java SE 6)\&.

.TP

-xmlschema

.br

Treats input schemas as W3C XML Schema (default)\&. If you do not specify this switch, then your input schemas are treated as though they are W3C XML Schemas\&.

.TP

-relaxing

.br

Treats input schemas as RELAX NG (experimental and unsupported)\&. Support for RELAX NG schemas is provided as a JAXB Vendor Extension\&.

.TP

-relaxing-compact

.br

Treat input schemas as RELAX NG compact syntax (experimental and unsupported)\&. Support for RELAX NG schemas is provided as a JAXB Vendor Extension\&.

.TP

-dtd

.br

Treats input schemas as XML DTD (experimental and unsupported)\&. Support for RELAX NG schemas is provided as a JAXB Vendor Extension\&.

.TP

-wsdl

.br

Treats input as WSDL and compiles schemas inside it (experimental and unsupported)\&.

.TP

-quiet

.br

Suppress compiler output, such as progress information and warnings\&.

.TP

-verbose

.br

Be extra verbose, such as printing informational messages or displaying stack traces upon some errors\&.

.TP

-help

.br

Displays a brief summary of the compiler switches\&.

.TP

-version

.br

Displays the compiler version information\&.

.TP     

\fIschema file/URL/dir\fR

Specifies one or more schema files to compile\&. If you specify a directory, then the \f3xjc\fR command scans it for all schema files and compiles them\&.

.SS NONSTANDARD\ OPTIONS    

.TP

-XLocator

.br

Causes the generated code to expose SAX Locator information about the source XML in the Java bean instances after unmarshalling\&.

.TP

-Xsync-methods

.br

Causes all of the generated method signatures to include the \f3synchronized\fR keyword\&.

.TP

-mark-generated

.br

Marks the generated code with the annotation \f3@javax\&.annotation\&.Generated\fR\&.

.TP

-episode file

.br

Generates the specified episode file for separate compilation\&.

.SS DEPRECATED\ AND\ REMOVED\ OPTIONS    

.TP

-host & -port

.br

These options are replaced with the \f3-httpproxy\fR option\&. For backward compatibility, these options are supported, but will not be documented and might be removed from future releases\&.

.TP

-use-runtime

.br

Because the JAXB 2\&.0 specification has defined a portable runtime environment, it is no longer necessary for the JAXB RI to generate \f3**/impl/runtime\fRpackages\&. Therefore, this switch is obsolete and was removed\&.

.TP

-source

.br

The \f3-source\fR compatibility switch was introduced in the first JAXB 2\&.0 Early Access release\&. This switch is removed from future releases of JAXB 2\&.0\&. If you need to generate 1\&.0\&.x code, then use an installation of the 1\&.0\&.x code base\&.

.SH COMPILER\ RESTRICTIONS    

In general, it is safest to compile all related schemas as a single unit with the same binding compiler switches\&. Keep the following list of restrictions in mind when running the \f3xjc\fR command\&. Most of these issues only apply when you compile multiple schemas with multiple invocations of the \f3xjc\fR command\&.

.PP

To compile multiple schemas at the same time, keep the following precedence rules for the target Java package name in mind:

.TP 0.4i    

1\&.

The \f3-p\fR option has the highest precedence\&.

.TP 0.4i    

2\&.

\fIjaxb:package\fR customization\&.

.TP 0.4i    

3\&.

If \f3targetNamespace\fR is declared, then apply the \f3t\fR\f3argetNamespace\fR to the Java package name algorithm defined in the specification\&.

.TP 0.4i    

4\&.

If no \f3targetNamespace\fR is declared, then use a hard coded package named \f3generated\fR\&.

.PP

You cannot have more than one \fIjaxb:schemaBindings\fR per name space, so it is impossible to have two schemas in the same target name space compiled into different Java packages\&.

.PP

All schemas being compiled into the same Java package must be submitted to the XJC binding compiler at the same time\&. They cannot be compiled independently and work as expected\&.

.PP

Element substitution groups that are spread across multiple schema files must be compiled at the same time\&.
