Subject RE: creating ejb-jar problem - resolving dtd
Date Thu, 15 Nov 2001 15:22:28 GMT
James,

We had the same problem beginning November 8th, and using the dtd element
(as suggested by Andy below) was also the approach we took.  I imagine
java.sun.com must have changed something on their website.  I could view the
DTD from java.sun.com in a web browser, but could no longer access it from a
Java program (using URL and URLConnection, and ultimately any XML parser or
Ant).  I emailed java.sun.com's web staff, but they directed me elsewhere.

Well, the local DTD solution works, and presumably it's more reliable and
faster than getting it over the net anyway.

An alternative solution: sticking weblogic.jar in Ant's own classpath.
weblogic.jar contains the DTDs, too.  I wanted to keep weblogic.jar out of
Ant's classpath, though.

Jim
