Why do I obtain a Java error when I try to configure the Reuters Data Service to work with the Datafeed Toolbox 3.0 (R2007b)?

I obtain a Java error when I try to configure the Reuters to work with the Datafeed Toolbox 3.0 (R2007b).

These errors occur when you attempt to use the Reuters Configuration Editor to configure connections on a machine on which an XML Parser is not installed.

ERROR: java com.reuters.rfa.tools.config.editor.ConfigEditor

org.xml.sax.SAXException: System property
org.xml.sax.driver not specified at org.xml.sax.helpers.XMLReaderFactory.createXMLReader(Unknown Source)

at (com.reuters.rfa.tools.config.editor.ConfigEditor.(ConfigEditor.java:61)
at com.reuters.rfa.tools.config.editor.ConfigEditor.main(ConfigEditor.java:1303)

I am following the procedure described in the documentation titled: "About Data Servers and Data Service Providers".

To address this issue, download an XML parser file and then include a path to this file in your CLASSPATH environment variable.

To set your CLASSPATH environment variable to include the XML parser file C:\xerces.jar (downloaded from

https://xerces.apache.org/xerces-j/index.html

), execute the following at the Windows Command prompt:

set CLASSPATH=%CLASSPATH%;matlabroot\toolbox\datafeed\datafeed\config_editor.jar;C:\xerces.jar

where 'matlabroot' is the MATLAB installation directory found by executing MATLABROOT at the MATLAB command prompt.

Then run the Configuration Editor as follows:

java -Dorg.xml.sax.driver=org.apache.xerces.parsers.SAXParser com.reuters.rfa.tools.config.editor.ConfigEditor
