Generator: resolving database.dtd in
org.apache.torque.engine.database.transform.DTDResolver.java
-------------------------------------------------------------------------------------------------
Key: TORQUE-3
URL: http://issues.apache.org/jira/browse/TORQUE-3
Project: Torque
Type: Improvement
Versions: 3.2
Environment: Windows XP, JDK 1.4 (I don't think this matters)
Reporter: George F.
Priority: Minor
In class org.apache.torque.engine.database.transform.DTDResolver the DTD for
the XMP schema files is retrieved via either a (1)
getResourceAsStream("database.dtd") call, a (2)
getInputSource("http://db.apache.org/torque/dtd/database_3_2.dtd";) or a (3)
getInputSource("systemId"), where systemId is typically made up of the system
designator in the DOCTYPE statement inside the XML schema file prepended with
the absolute path of the location of the current working directory or directory
from which the generator.
Usually the database.dtd is found in the class path (method 1), since it is
delivered with the generator jar. However, as soon as we do something like this
in the XML file: <!DOCTYPE database SYSTEM "database.dtd"> the generator does
not work any more, unless we place a copy of database.dtd at the current
working directory (thus, system reverts to (3)). This behaviour comes from this
line in method resolveEntity:
if (databaseDTD != null && (WEB_SITE_DTD.equals(systemId))
since the systemId in this case looks something like this:
file:///d:torque/torque-gen-3.2/database.dtd and of course does not match the
WEB_SITE_DTD string.
My suggestion : change this line to
if (databaseDTD != null)
and everything works fine.
