[jboss-dev] Redeploy an app if xml is added to metadata location?
I just noticed that we redeploy an entire application if a xml file gets
added/removed from the metadata locations of a application. For example,
if in an exploded WAR file we add a somefile.xml to the WEB-INF folder
the application gets redeployed (easily reproducible in ROOT.war). Why
do we do this? I thought redeploy would be triggered by touching the
deployment descriptor of the app (i.e. changing the last modified time
of web.xml). Looks to be intentional from what i see in the
configurations (profile.xml):
<!-- This just checks metadata locations -->
<bean name="MetaDataStructureModificationChecker"
class="org.jboss.deployers.vfs.spi.structure.modified.MetaDataStructureModificationChecker">
<constructor>
<parameter><inject bean="MainDeployer" /></parameter>
</constructor>
<property name="cache"><inject bean="StructureModCache"
/></property>
<property name="filter"><bean
class="org.jboss.system.server.profile.basic.XmlIncludeVirtualFileFilter"
/></property>
</bean>
org.jboss.deployers.vfs.spi.structure.modified.MetaDataStructureModificationChecker.hasStructureBeenModifed(...):
// do we have some new files or some were deleted
if (leaves != null && children != null &&
leaves.size() != children.size())
{
if (log.isTraceEnabled())
log.trace("Metadata files number changed, old: "
+ leaves + ", now: " + children);
return true;
}
Why do we have to redeploy the application if a xml is added to the
metadata folder of a application?
