[jbosstools-issues] [JBoss JIRA] Commented: (JBIDE-4686) "Server returned HTTP response code: 503" warning during HTML/XHTML validation

[Victor Rubezhny (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBIDE-4686?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12484553#action_12484553 ] 

Victor Rubezhny commented on JBIDE-4686:
----------------------------------------

The situation is a little bit strange for me... The pointed DTD is defined in XML Catalog, and the XML Catalog in its turn is used by the resolver to get the DTD's location.

So, I see the only one reason of the issue reproduced by Julien Kronegg - is some problem with WTP WST version/installation (for example for some reason there is no  -//W3C//DTD XHTML 1.0 Transitional//EN DTD defined in the XML Catalog in Julien's environment).

I'm ready to commit a code of DTD resolver that searchs for the DTDs and Schemas in an alternate way for the WST-defined ones. 
Is it really needed?

> All HTML/XHTML files are validated with a warning "Server returned HTTP response code: 503 for URL: http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd". W3C site (the one that hosts the referenced XHTML/HTML DTDs) has the following explanation: http://www.w3.org/blog/systeam/2008/02/08/w3c_s_excessive_dtd_traffic. Basically, they now block IPs for machines that request their DTDs too often, and recommend to cache the DTD instead of requesting it every time. Apparently, the JBoss Tools validator is one of the affected ones.
> The solution is simple - please cache the DTDs, given that they're highly unlikely to EVER change.
> Upd: affects M2 version of JBoss Tools as well, not just M1
