Question

Hi,
When our Weblogic 10.3 server starts our web application, it tries to validate every xml file (tld, web.xml ...) against their schema but our server is not connected to internet. The Weblogic server has to wait the connection timeout for every file and that makes our deploying process very long.
How can we disable this behavior?

Hi Vijay,
The message "could not connect over HTTP to server: 'java.sun.com'" in the error indicates that WLS is not able to reach the site with dtd for validating a tag library definition (tld). The long time to deploy is because WLS tries to connect until it times out.
This issue was reported on bugs 8176755, 8546969 and 12760483, which indicate this is caused by:
Having the wstx-asl JAR in the EAR's APP-INF/lib
Having a <prefer-application-packages> entry in weblogic-application.xml
The Woodstox behavior is per the Stax specification.
"Stax specification defines that all standard configuration settings need to be available on per-factory basis (readable via instances, but there's no support for setting). Woodstox reader/writer instances do actually allow you to modify settings, although whether changes have any effect depends both on instance state (some settings are only relevant at instance construction) and property itself."
Reference :
http://old.nabble.com/IOException-when-reading-external-dtd%27s-tt10716015.html#a10716015
for this solution.
There is a bug 8176755 existing for this issue. Patches are available from WLS 10.3.0 through WLS 10.3.2.
Below are the available workarounds for the versions of WLS for which the patches are not available:
1. Add below option to the WebLogic startup script to use WLS implementation instead of Woodstox
-Djavax.xml.stream.XMLInputFactory=weblogic.xml.stax.XMLStreamInputFactory
2. Set SUPPORT_DTD property (for XMLInputFactory) to Boolean.FALSE. With Woodstox, this disables handling of DTD subsets (both internal and external), without causing exceptions. Other implementations may throw an exception upon encountering DOCTYPE declaration, apparently this is what sjsxp 1.0 does.
3. Define XMLInputFactory.RESOLVER to point to dummy resolver that just resolves all references (including external reference from DOCTYPE) into empty resource. Something like:
inputFactory.setProperty(XMLInputFactory.setXMLResolver, new XMLResolver() {
public Object resolveEntity(...) {
return new StringReader("");
