XMLmind XML Editor - Configuration and Deployment |
During its startup, the XMLmind XML Editor desktop application recursively scans the contents of its two addon/ directories looking for add-ons.
These two addon/ directories are XXE_install_dir/addon/XXE_user_preferences_dir/addon/addon/ directories of XMLmind XML Editor?.
![[Important]](images/important.svg) | The "Quick Start Cache" prevents the dynamic discovery of add-ons |

Once the XMLmind XML Editor desktop application has recursively scanned the contents of its two Therefore the dynamic discovery of add-ons is performed only when the "Quick Start Cache" is empty (or disabled once for all). The "Quick Start Cache" is automatically cleared when:
Manually clearing the "Quick Start Cache" is normally done by using the button found in → , Advanced|Cached data in XMLmind XML Editor - Online Help. However it's often quicker to simply delete the |
An add-on may comprise many different kinds of files. These files must follow the conventions below in order to be dynamically discovered by XXE.
A .jar file contains compiled Java™ code.
![[Note]](images/note.svg) | About JAR files containing native libraries | ||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|
Some JAR files may contain native libraries. For example: When this is the case, it is recommended to create one JAR file per OS/architecture and to give these JAR files filenames following the convention explained below. For example, By doing this, you'll instruct XXE, for example, to ignore Filename syntax: jar_basename ->

XXE configuration files are XML files:
with a file name ending with ".xxe",
validated by XML schema with http://www.xmlmind.com/xmleditor/schema/configuration as its target namespace,
with a root element named configuration,
this root element having a name attribute,
containing a detect element.
Several configurations may have the same name. For example, a user may have defined its own configuration named "DocBook" including bundled configuration also named "DocBook" but adding element templates and keyboard shortcuts (see include, elementTemplate, binding). In such case, only one configuration named "DocBook" is kept by XXE: the configuration with highest priority.
Configurations loaded from the addon/ subdirectory of user preferences directory have priority over configurations loaded from the value of environment variable XXE_ADDON_PATH (see below) which in turn have priority over configurations loaded from the addon/ subdirectory of XXE installation directory.
Configurations having the same priority are sorted using their file basenames. Example: file:///opt/xxe/foo/0docbook.xxe is tested before file:///opt/xxe/bar/docbook.xxe when trying to detect the class of a document because 0docbook.xxe lexicographically precedes docbook.xxe.
XML catalogs are XML files:
with a file name ending with "atalog.xml",
which conform to the OASIS catalog DTD.
Example:
<?xml version="1.0" ?>
<!DOCTYPE catalog PUBLIC "-//OASIS//DTD XML Catalogs V1.0//EN"
"http://www.oasis-open.org/committees/entity/release/1.0/catalog.dtd">
<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog"
prefer="public">
<public publicId="-//W3C//DTD SVG 1.1//EN"
uri="common/dtd/svg11/svg11.dtd"/>
</catalog>Note that specifying the above <!DOCTYPE> will not cause the XML catalog parser to download XML Catalog DTD, catalog.dtd, from the Web.
XXE uses XML Catalogs not only to resolve the locations of the DTD and other external entities, but also to resolve URLs found in the following places:
Schema locations in xsi:schemaLocation and in xsi:noNamespaceSchemaLocation.
Schema locations in xs:include, xs:redefine, xs:import.
Schema locations in <?xml-model href="..."?>.
Document locations passed to the document() XPath function.
All XXE configuration elements referencing an URL. Example: <include location="..."/>.
CSS style sheet locations in @import.
CSS style sheet locations in <?xml-stylesheet href="..."?>.
XSLT style sheets in the transform child element of a process command.
Resources in the copyProcessResource child element of a process command.
XSLT style sheets included or imported by other XSLT style sheets (that is, the XML Catalogs used by XXE are passed to Saxon, the XSLT engine bundled with XXE).
The href attribute of xi:include elements (XInclude).
Spell-checker plug-ins are contained in Java™ JAR files:
with a file name ending with "_spellchecker.jar",
implementing service com.xmlmind.xmleditapp.spellchecker.SpellCheckerFactory.
The exact structure of a plug-in jar (manifest, service providers, etc) is described in Chapter 13, Spell checker plug-in in XMLmind XML Editor - Developer's Guide.
XMLmind spell-checker dictionaries are themselves add-ons which are contained in Java™ JAR files:
with a file name ending with ".dar",
having a basename which is the ISO code of a language (e.g. fr, fr-CH, en, en-US, etc).
XSL-FO processor plug-ins are contained in Java™ JAR files:
with a file name ending with "_foprocessor.jar",
implementing service com.xmlmind.foprocessor.FOProcessor.
Image toolkit plug-ins are contained in Java™ JAR files:
with a file name ending with "_imagetoolkit.jar",
implementing service com.xmlmind.xmledit.imagetoolkit.ImageToolkit.
Virtual drive plug-ins are contained in Java™ JAR files:
with a file name ending with "_vdrive.jar",
implementing service com.xmlmind.xmleditapp.vdrive.DriveFactory.
Document format (that is, document formats other than XML, like Markdown or JSON) plug-ins are contained in Java™ JAR files:
with a file name ending with "_docformat.jar",
implementing service com.xmlmind.xmleditapp.docformat.DocumentFormat.
Such customizations are contained in XML files called customize.xxe_gui and conforming to the "http://www.xmlmind.com/xmleditor/schema/gui" W3C XML Schema.
Such GUI specification files are described in XMLmind XML Editor - Customizing the User Interface.
If during its start-up, XXE finds several customize.xxe_gui files, it will merge their contents with the base GUI specification (by default, xxe-gui:DesktopApp.xxe_gui, which is a resource contained in xxe.jar).
