Here is an overview of the issue:
---------------------------------------------------------------------
Key: XERCESJ-976
Summary: System properties should not be used to configure parser
Type: Improvement
Status: Unassigned
Priority: Major
Project: Xerces2-J
Components:
XNI
Versions:
2.6.2
Assignee:
Reporter: elharo
Created: Thu, 3 Jun 2004 8:51 AM
Updated: Thu, 3 Jun 2004 8:51 AM
Environment: All
Description:
The use of system properties to configure the parser is a major problem in many
environments. In particular the org.apache.xerces.xni.parser
.XMLParserConfiguration is causing major troubles. Among these:
1. It is impossible to set this property in an applet environment due to
security restrictions.
2. While this property can be set in a server-side environment, it then affects
all classes loaded on the server, even those loaded by a different class loader
which may not have access to the class org.apache.xerces.xni.parser
.XMLParserConfiguration points to. Setting this property in one servlet can
break otehr servlets that also dependn on Xerces.
3. Different parser objects used for different purposes may require different
configurations. This is not possible when one system property controls them all
.
A *method* such as setParserConfiguration() should be provided that replaces
this system property. Furthermore, this method should have object-scope rather
than system-scope so it's possible for different applications running in the
same VM as is common in server environment, to configure their parsers
differently. Several XOM users have reported different problems that all trace
back to this system property and its global scope.
