Hi Gerry,
Ok, it's not totally what I expected but I really appreciate your effort. And in fact you were pretty close, so here's the mail I would have liked to read:
When I try to run an Xupdate query, I receive the following exception:
org.xmldb.api.base.XMLDBException: Query error: java.lang.Exception: java.lang.NoClassDefFoundError: org/apache/xerces/framework/XMLParser
I first wanted to write a test to reproduce the bug. I looked into the java/tests/org/apache/xindice/integration/client and noticed the CollectionTest and DocumentTest. So I did some copy/paste with the example found in the xindice/java/example/xml folder and I came up with the following test:
public class XUpdateQueryTest
extends AbstractXmlDbClientTest { public void testUpdateDocument()
throws Exception {
String document = "<?xml version=\"1.0\"?>" +
"<person>" +
"<fname>John</fname>" +
"<lname>Smith</lname>" +
"<phone type=\"work\">563-456-7890</phone>" +
"<phone type=\"home\">534-567-8901</phone>" +
"<email type=\"home\">[EMAIL PROTECTED]</email>" +
"<email type=\"work\">[EMAIL PROTECTED]</email>" +
"<address type=\"home\">34 S. Colon St.</address>" +
"<address type=\"work\">9967 W. Shrimp Ave.</address>" +
"</person>"; this.client.insertDocument(TEST_COLLECTION_PATH, "xupdatedoc",
document);
assertEquals(1, this.client.countDocument(TEST_COLLECTION_PATH)); String xupdate = "<xu:modifications version=\"1.0\"" +
" xmlns:xu=\"http://www.xmldb.org/xupdate\";>" +
" <xu:remove select=\"/person/[EMAIL PROTECTED] = 'home']\"/>" +
" <xu:update select=\"/person/[EMAIL PROTECTED] = 'work']\">" +
" 480-300-3003" +
" </xu:update>" +
"</xu:modifications>"; String updatedDocument = "<?xml version=\"1.0\"?>" +
"<person>" +
"<fname>John</fname>" +
"<lname>Smith</lname>" +
"<phone type=\"work\">408-300-3003</phone>" +
"<email type=\"home\">[EMAIL PROTECTED]</email>" +
"<email type=\"work\">[EMAIL PROTECTED]</email>" +
"<address type=\"home\">34 S. Colon St.</address>" +
"<address type=\"work\">9967 W. Shrimp Ave.</address>" +
"</person>"; Collection col = this.client.getCollection(TEST_COLLECTION_PATH);
XUpdateQueryService service = (XUpdateQueryService)
col.getService("XUpdateQueryService", "1.0"); long count = service.update(xupdate);
assertEquals(1, count); String doc = this.client.getDocument(TEST_COLLECTION_PATH,
"xupdatedoc");
assertNotNull(doc);
assertEquals(updatedDocument, doc); this.client.removeDocument(TEST_COLLECTION_PATH, "xupdatedoc");
assertEquals(0, this.client.countDocument(TEST_COLLECTION_PATH));
}}
2 things to notice: - since we are testing a service, I created a new package - I do not work with files but with Strings. It will be easier to execute the tests on different platforms.
When I execute the tests, I have the following error:

Hurra, I have the same error (except that I run the embed version, but in this case it doesn't matter).
Ok I noticed that the first line is XUpdateQueryResolver, line 142. This line calls the constructor of XUpdateQueryImpl. It's reasonable that the error comes from this code. This class is from the xmldb xupdate package so I checked out the xmldb project and this project uses the xerces-1.4.3.jar version. I guess it's where the problem comes from.
I sent a mail to the xapi-dev mailing list to let them know about the problem.
In the meantime, we have a new (failing) test and I hope that everything will be fixed pretty soon. Since it's quite urgent for me.
---- end of message --->
Writing the mail took me twice the time I needed to write the test and find the problem and send the mail to the xapi-dev guys. I don't want to blame anybody, but just show that writing a test can really help finding the errors.
Hope this will inspire other.
Regards,
-Vladimir
