In complex IT environments it is necessary to integrate different information systems with each other, exchange data between tools and automate actions and function calls depending on events arising from user interaction. To meet the requirements of integration building usually means to implement APIs and to create tool-to-tool bridges. Web Services can help to clean up bridges into interfaces as well as to abstract functions from their underlying platform and implementation. These are the major goals of the loosely coupled integration strategy which is in turn one essential idea of a service-oriented architecture (SOA). provide a low level set of functions and web services. These can be orchestrated into services and used in business processes which make up the execution part of a SOA environment. is an add-on to XBridgeNG 2.0. It runs standalone or in combination with XBridgeNG. Pure XBridgeNG has two components: XML Schema for item based data types (e.g. tickets from a bug tracker system or a database record) Set of Apache Ant tasks to function as a bridge between the XBridgeNG XML format at legacy 3rd party software (e.g. HP Quality Center, Serena TeamTrack, ...) The add Web Services (SOAP) wrapper around Apache Ant tasks (since XBridgeNG 2.0) The current focus is on file-based operations. do not contain an integration server or a process execution engine. This chapter describes the installation.

tbd. Sun Java SE 1.6.0 Apache Tomcat 7 tbd. In short: Deploy .WAR file to Apache Tomcat

There is a quick guide explaining Basic Authentication for Tomcat here: http://oreilly.com/pub/a/java/archive/tomcat-tips.html?page=1

Sometimes you'll only want to restrict access to to only specified host names or IP addresses. This way, only clients at those specified addresses can use the web services. Tomcat provides two configuration values for that: RemoteHostValve and RemoteAddrValve. These Valves allow you to filter requests by host name or by IP address, and to allow or deny hosts that match. The example below restricts access to the ArchiveService from any machine that is not the local host. <Context path="/XService/ArchiveService" ...> <Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="127.0.0.1" deny=""/> </Context> If no allow pattern is given, then patterns that match the deny attribute patterns will be rejected, and all others will be allowed. Similarly, if no deny pattern is given, patterns that match the allow attribute will be allowed, and all others will be denied. The <context> element must be placed into the server.xml file (into <engine><host>).

List of available web services and their operations.

The ArchiveService bundles file packing operations. Its WSDL is located at http://server:port/XServices/ArchiveService?wsdl

The ExecuteService bundles local and remote command execution operations. Its WSDL is located at http://server:port/XServices/ExecuteService?wsdl

provides remote execution facilities with authentication based on user names and passwords.

Run an executable with arguments on the server providing the web service. The command is run within the environment and under the user privileges of the user who is running the Tomcat Server.

parameter type required description executable String Yes Command to be run. The command may be specified with full path using forward slash "/" as path separator. argline String No Any command line arguments timeout Long Yes Timeout in milliseconds. The command is forcefully terminated when timeout is reached.

Runs a telnet session with an "expect shell" like behaviour.

parameter type required description host HostConnection Yes Host to connect to (see: tns:HostConnection) prompt String No The prompt string to expect after login. This is used to recognize when the session is open. command String No The command to execute. expect String No The prompt to expect after the command has been executed successfully. timeout Long Yes Timeout in milliseconds.

The FileServces bundles various file operations. Its WSDL is located at http://server:port/XServices/FileService?wsdl

The MiscService bundles various operations. Its WSDL is located at http://server:port/XServices/MiscService?wsdl

This chapter bundles the documentation for common XML types used by XServices web service.

The AntProperty type defines a list of key/value pairs. The defining Java class is net.brutex.xservices.types.AntProperty . ]]> key2 value2 ]]>

The FileResource type defines an URI to a file with optional on-the-fly decompression. The defining Java class is net.brutex.xservices.types.FileResource . ]]> Available types: FILE: URI points to a local file resource. Examples: c:\temp\something.txt, c:/dir/another.file, /home/brian/file URL: File from URL (http, https, ftp, ...). Example: http://brutex.net/file.pdf GZIP and BZIP2: File from a local file system with on-the-fly decompression. FILE c:\temp\xservices.war ]]>

The HostConnection type identifies a server resource and login credentials. The defining Java class is net.brutex.xservices.types.HostConnection . Schema definition ]]> Example XML server.brutex.net 512 brian somepass ]]>

The PatternElement type defines single string pattern for file/ directory matching. The defining Java class is net.brutex.xservices.types.PatternElement . These patterns look exactly like those used in Apache Ant Patterns. The '*' matches zero or more characters and the '?' will match a single character. Both symbols can be combined in one pattern. The '**' symbol can be used to match any directory deepth. Some example patterns: **/mydir/** Match all file that are located in any directory that has "mydir" string in its pathname. Also applies to files with "mydir" in their name. /mydir/ The parser will automatically append an '**' symbol, thus the resulting pattern is /mydir/**. All files below the "/mydir/" directory (including its sub-directories will be chosen. The pattern is OS independent. You should always use "/" as path separator, even on windows based systems.
