Why my Eclipse requests for "http://www.w3.org/2001/xml.xsd" and fails often

I'm using Eclipse JavaEE IDE edition Indigo Release (build id:20110615-0604) to develop Tomcat-based java web applications, and I've no plan to write anything about Web Service.

However, when I created a new Java web project in Eclipse, it will automatically include a node named "JAX-WS Web Services" in the project explorer, which I don't find a way to exclude.

And more inconveniently: Everyday I first time launch my Eclipse and click to expand the project node in the project explorer, the whole Eclipse IDE will be stuck for a long while (about one or two minutes).

I thought it should be something wrong with the "JAX-WS Web Services" node. So I used Fiddler to track the requests and responses.

I found that when I click to expand the project node, Eclipse will request for:

  • (a) http: //java.sun.com/xml/ns/j2ee/web-app_2_4.xsd
  • (b) http: //java.sun.com/xml/ns/j2ee/j2ee_1_4.xsd
  • (c) http: //www.ibm.com/webservices/xsd/j2ee_web_services_client_1_1.xsd
  • (d) http: //www.ibm.com/software/info/webservices/xsd/j2ee_web_services_client_1_1.xsd
  • (e) http: //www-01.ibm.com/software/info/webservices/xsd/j2ee_web_services_client_1_1.xsd
  • (f) http://www.w3.org/2001/xml.xsd

And the last one (f) will last for a long time to retrieve, and have a high failure rate (HTTP 504). I believe this is the reason why Eclipse stuck.

I want to know: How to fix or avoid this problem?

Thanks!

I tried doing the same process, but I got a web project without JAX-WS services. puzzled. – Sajan Chandran

You may have an XML Schema that references it, like so:

<xsd:import namespace="http://www.w3.org/XML/1998/namespace"
            schemaLocation="http://www.w3.org/2001/xml.xsd"/>

If so, download xml.xsd and make a local copy. Change the import accordingly, perhaps like so:

<xsd:import namespace="http://www.w3.org/XML/1998/namespace"
            schemaLocation="xml.xsd"/>

Alternatively, change the import to the most current version of the file:

<xsd:import namespace="http://www.w3.org/XML/1998/namespace"
            schemaLocation="http://www.w3.org/2009/01/xml.xsd"/>

Some have reported that this link is faster, but it is subject to becoming outdated.

Perhaps make an entry for that file in the XML Catalog, Window > Preferences > XML > XML Catalog, or enable caching in Window > Preferences > General > Network Connection > Cache
