Files marked as [external] are included in the URE installation because the URE
needs them
and it cannot be guaranteed that they are available on a given
system. Applications
using the URE may need those files too, so they are made
available as non-private files of the URE installation. However, in an ideal
world, those files would
not need to be included in the URE installation.
Files marked as [
private] are
private to the URE installation. To avoid
stability issues, applications that use the URE should
not access the
functionality of these files.
Files marked as [GAC] are installed in the Global Assembly Cache on Windows. The
file path reflects the path as seen in the Explorer with the Assembly
Cache Viewer Tool (Shfusion.dll) installed. The actual paths are different.
Public Files in a URE Installation
----------------------------------
A URE installation contains the following
public files:
- uno is the executable file that runs UNO components.
For more details, see
the SDK Developer
's Guide.
- regview is a tool that works with old-format binary registries that contain
UNO type
or UNO service information.
For more details, see the SDK Developer
's
Guide.
- javaldx is a helper program on Linux, Solaris,
and *BSD that
enables Java executables to use a Java VM, such as OpenJDK
or the Sun JDK/JRE.
Executables such as uno run
this helper automatically.
- cppu, cppuhelper, purpenvhelper, sal,
and salhelper are the
public C++ UNO
runtime dynamic libraries that client code can call.
For details on the
functionality that these libraries offer, see the
"C++ Reference" section of the
SDK HTML documentation. The corresponding C++ header files are
not in the URE,
but rather in the SDK.
- libreoffice.jar
and unoloader.jar are the
public Java UNO runtime
Java[tm] Archives (JARs) that client code can call.
juh.jar, jurt.jar, ridl.jar, unoil.jar are still provided
for backwards compatibility,
but are basically empty
and have been merged into libreoffice.jar.
For details on the functionality that these files offer, see the
"Java UNO Runtime Reference" section of the SDK HTML documentation.
- types.rdb
and services.rdb are preconfigured UNO type
and service registries.
For more details, see the
"Deploying a URE" section of
this README.
Deploying a URE
---------------
By
default, the URE is installed in /opt/libreoffice/ure on Linux,
Solaris,
and *BSD,
and in Program Files\URE on Windows.
If you
want, you can override
this location when you install the URE,
for example, with
rpm --relocate on Linux. The URE is designed so that multiple instances of the
URE can coexist on a single system in different locations.
On Windows, the path to the installed URE is stored in the registry under the
path
"HKEY_CLASSES_ROOT\Software\LibreOffice\URE" and key
"Path".
UNO Deployment Variables
------------------------
The URE installation is preconfigured with several UNO types
and UNO services.
The available types
and services are listed in the types.rdb
and services.rdb
files respectively. The location of these files is stored by two UNO deployment
variables, namely UNO_TYPES
and UNO_SERVICES. These variables are set up by a
unorc
or uno.ini that is
private to the URE installation.
This private file
also contains the
private deployment variables URE_INTERNAL_LIB_DIR,
URE_INTERNAL_JAVA_DIR,
and URE_INTERNAL_JAVA_CLASSPATH, which are required by
the URE.
The UNO_TYPES
and UNO_SERVICES variables automatically search the following
locations
for types.rdb
and services.rdb files:
Linux, Solaris,
and *BSD:
- <URE installation>/share/misc/ types.rdb
and services.rdb, respectively
- any URLs listed in the
public deployment variables URE_MORE_TYPES
and
URE_MORE_SERVICES, respectively
Windows:
- <URE installation>\misc\ types.rdb
and services.rdb, respectively
- any URLs listed in the
public deployment variables URE_MORE_TYPES
and
URE_MORE_SERVICES, respectively
NOTE: The URE on Windows does
not support a system-wide deployment of additional
types.rdb
and services.rdb files. That is, you cannot store additional
types.rdb
and services.rdb files in a Documents
and Settings\All
Users\Application Data\URE directory.
URE_MORE_TYPES
and URE_MORE_SERVICES each contain zero
or more space-separated
URI descriptors. A URI descriptor is either a URI (denoting an individual file)
or a URI embedded in
"<" and ">*" (denoting all the files contained non-
recursively within the directory denoted by the given URI).
The Java UNO environment needs type information in the form of Java
class files
instead of rdb files. Additional types are searched
for in any URLs listed in
the
public deployment variable URE_MORE_JAVA_TYPES.
For details on how to override the UNO deployment variables, see the SDK
Developer
's Guide or go to http://udk.openoffice.org/common/man/concept/
micro_deployment.html.
URE Java Framework
------------------
When a URE executable, such as uno, starts a Java VM, the URE Java Framework
searches
for a suitable JDK/JRE installation.
For more information on the URE
Java Framework, go to http:
//udk.openoffice.org/common/man/spec/
javavendorextension.sxw. The
private javavendors.xml file in a URE installation
provides preconfigured support
for various JDK/JRE versions. The
private
jvmfwk3rc
or jvmfwk3.ini file specifies the location of a suitable JDK/JRE
installation. When an executable tries to start a Java VM, the URE searches the
relevant Java settings file
for information on a suitable JDK/JRE version.
NOTE: On any platform, you can
delete the javasettings_${_OS}_${_ARCH}.xml file
if the file contains problematic stale data.
By
default, the URE does
not search
for a Java settings file, but instead
searches
for a suitable JDK/JRE installation whenever necessary. You can
override
this by setting the URE_OVERRIDE_JAVA_JFW_SHARED_DATA
and
URE_OVERRIDE_JAVA_JFW_USER_DATA deployment variables.
If
URE_OVERRIDE_JAVA_JFW_USER_DATA is set, the URE will update the relevant
information in
${URE_OVERRIDE_JAVA_JFW_USER_DATA}/javasettings_${_OS}_${_ARCH}.xml when it
searches
for a suitable JDK/JRE installation. You can also use the
UNO_JAVA_JFW_JREHOME deployment variable to specify the location of a JDK/JRE
installation.
For more information on
this variable, see
http:
//udk.openoffice.org/common/man/spec/javavendorextension.sxw.
The URE allows clients to extend the content of UNO_JAVA_JFW_CLASSPATH_URLS (see
http:
//udk.openoffice.org/common/man/spec/javavendorextension.sxw): The content
of the
public deployment variable URE_MORE_JAVA_CLASSPATH_URLS,
if set, is
added to the end of the URE
's UNO_JAVA_JFW_CLASSPATH_URLS list.
You might experience problems in an SDK environment that uses different JDK/JRE
versions
for the SDK
and the URE.
This problem arises when the OO_SDK_JAVA_HOME
SDK environment variable specifies a different Java VM than the Java VM that is
used in the URE Java Framework. See the
"Installation Guide" section of the SDK
HTML documentation to find out how to set the OO_SDK_JAVA_HOME environment
variable.
C++
and Java UNO Components
---------------------------
C++ UNO components run from within the uno executable can depend on an
environment in which the
public C++ UNO runtime dynamic libraries (cppu,
cppuhelper, purpenvhelper, sal, salhelper)
and the external dynamic libraries
(libxml2 etc.) are already available (that is, on Linux, Solaris,
and
*BSD, a component dynamic library need
not make sure that the UNO
runtime dynamic libraries it needs can be found on its RPATH).
Similarly, Java UNO components can depend on an environment in which the
public
Java UNO runtime JARs are already available (that is, a component JAR need
not
list in its manifest Class-Path the UNO runtime JARs it needs).
If a Java UNO component requires additional UNO types, use the UNO-Type-Path
manifest entry to specify the location of the UNO types. The UNO-Type-Path is
similar to the Class-Path manifest entry
and can contain URLs of JARs
and
directories that contain the Java classes that represent additional UNO types.
The UnoClassLoader evaluates the UNO-Type-Path manifest entry to ensure that the
additional UNO types are available to the Java UNO environment.
The UNO-Type-Path can have the following entries:
- UNO-Type-Path:
Current JAR does
not contain UNO types.
- UNO-Type-Path: <>
Current JAR contains UNO types.
- UNO-Type-Path: any/other/jar.jar yet/another/jar.jar
Current JAR brings other JARs that contain UNO types.
- UNO-Type-Path: any/other/jar.jar <> yet/another/jar.jar
Current JAR
and other JARs that the current JARs uses contain UNO types.
NOTE:
If you
do not include the UNO-Type-Path manifest entry, the URE assumes
that the current JAR contains UNO types.
If a Java application requires the Java UNO environment, the UnoClassLoader must
be set up to load the relevant Java classes.
For example, Runner.java in the
uretest bundle is packed as runner.jar, which the makefiles use to launch the
javaclient.jar application.
For more information, see
com.sun.star.lib.unoloader.UnoClassLoader
and
com.sun.star.lib.unoloader.UnoLoader in the
"Java UNO Runtime Reference" section
of the SDK HTML documentation.
