TestNG/SeamTest NPE in xml parsing

[vijayamaladoss]

I am trying to Unit test entities using SeamTest and TestNG. I have a strange problem in running TestNG(SeamTest). When I am connected to internet
running a ant test throws a exception shown below.

test:
 [testng] Exception in thread "main" java.lang.NullPointerException
 [testng] at org.testng.xml.Parser.parse(Parser.java:162)
 [testng] at org.testng.TestNG.setTestSuites(TestNG.java:472)
 [testng] at org.testng.TestNG.configure(TestNG.java:866)
 [testng] at org.testng.TestNG.privateMain(TestNG.java:822)
 [testng] at org.testng.TestNG.main(TestNG.java:802)

When I detach from internet it throws an exception(below) but continues to run tests.

test:
 [testng] java.net.UnknownHostException: hibernate.sourceforge.net
 [testng] at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:177)
 [testng] at java.net.Socket.connect(Socket.java:520)
 [testng] at java.net.Socket.connect(Socket.java:470)
 [testng] at sun.net.NetworkClient.doConnect(NetworkClient.java:157)

 [testng] at sun.net.www.http.HttpClient.openServer(HttpClient.java:522)
 [testng] at sun.net.www.http.HttpClient.<init>(HttpClient.java:231)

 [testng] at sun.net.www.http.HttpClient.New(HttpClient.java:321)
 [testng] at sun.net.www.protocol.http.HttpURLConnection.getNewHttpClient(

I understand this is something to do with validating parsers, but both xerces/xml-api is not in my class path as I am using seam-gen based application.

Any suggestions ???

May be parser tries to download dtd or scheme for some xml, check your installation of testng and *.xml that you wrote for your TestNG test. Also try to find where this string (hibernate.sourceforge.net) is present in your project, in which jar or file, or try to track which url is requested.

If that is the case, if I am connected to Internet, TestNG should not throw a NPE right?. as you suggested I searched for this url and I see this only in seam-gen.reveng.xml. This is of kinda weird

Then you have something wrong with the way you run tests. This is a line 162 from parser: List suiteFiles = currentXmlSuite.getSuiteFiles();

So null in list of suite. Check your TestNG xml file, run examples, or post your code, if you cannot solve it by yourself.
