Question

hi all,
i have a table with a xmltype-column (XmlSchema Support) and i wonna load(and validate) xml-data( as String) in the xmltype-column.
some thing like this :
int count=1;
String SQLTEXT=null;
Statement stmt=null;
ResultSet rs =null;
//while(count<=1000)
try
stmt = connection.createStatement();
rs = stmt.executeQuery("select SEQ_patxmlschema_ID.NEXTVAL from patxmlschema");
if(rs.next())
id =rs.getLong(1);
System.out.println(id);
stmt.close();
stmt=null;
rs.close();
SQLTEXT = "INSERT INTO patxmlschema(id, patID, name, status, patInfo)"+
          "VALUES(?,?,?,?,XMLType(?))";
pStmt = connection.prepareStatement(SQLTEXT);
long patID = random.nextInt(30000);
System.out.println("patId: "+ patID);
String name = RandomStringUtils.random(6,true,false);
System.out.println("lastname: "+ name);
String firstname=RandomStringUtils.random(5,true,false);
System.out.println("firstname: "+ firstname);
String status=RandomStringUtils.random(8,true,false);
System.out.println("status: "+ status);
String street=RandomStringUtils.random(6,true,false);
System.out.println("street: "+ street);
String zip=RandomStringUtils.random(5,false,true);
System.out.println("zip: "+ zip);
String city=RandomStringUtils.random(6,true,false);
System.out.println("city: "+ city);
String phone=RandomStringUtils.random(8,false,true);
String email=RandomStringUtils.random(15,true,false);
String state=RandomStringUtils.random(6,true,false);
String country=RandomStringUtils.random(6,true,false);
System.out.println("country: "+ country);
xmldoc=
     "<Patient>"+                    "xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'"+          "xsi:noNamespaceSchemaLocation='http://olidong.net/patInfo.xsd'>"+

     "</Patient>";
     pStmt.setLong(1, id);
     pStmt.setLong(2, patID);
     pStmt.setString(3, name);
     pStmt.setString(4, status);
     pStmt.setString(5, xmldoc);
     pStmt.executeUpdate();
pStmt.close();

hi Avi,
my xml doc is valid. with the sqlplus the are no problem or error. tryng the same with jddbc(thin driver) i got this error.
i don´t know, may be jdbc don´t support xml schema support insertion.
i got this sample:
DECLARE
doc VARCHAR2(2000) :=
'<schema
targetNamespace="http://xmlns.oracle.com/xdb/documentation/purchaseOrder.xsd"
xmlns:po="http://xmlns.oracle.com/xdb/documentation/purchaseOrder.xsd"
xmlns="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified">
<complexType name="PurchaseOrderType">
<sequence>
<element name="PONum" type="decimal"/>
<element name="Company">
<simpleType>
<restriction base="string">
<maxLength value="100"/>
</restriction>
</simpleType>
</element>
<element name="Item" maxOccurs="1000">
<complexType>
<sequence>
<element name="Part">
<simpleType>
<restriction base="string">
<maxLength value="20"/>
</restriction>
</simpleType>
</element>
<element name="Price" type="float"/>
</sequence>
</complexType>
</element>
</sequence>
</complexType>
<element name="PurchaseOrder" type="po:PurchaseOrderType"/>
</schema>';
BEGIN
DBMS_XMLSCHEMA.registerSchema(
'http://xmlns.oracle.com/xdb/documentation/purchaseOrder.xsd', doc);
END;
CREATE TABLE mypurchaseorders OF XMLType
XMLSchema "http://xmlns.oracle.com/xdb/documentation/purchaseOrder.xsd"
ELEMENT "PurchaseOrder"
VARRAY xmldata."Item" STORE AS TABLE item_nested;
INSERT INTO mypurchaseorders
VALUES(
XMLType(
'<PurchaseOrder
xmlns="http://xmlns.oracle.com/xdb/documentation/purchaseOrder.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation
= "http://xmlns.oracle.com/xdb/documentation/purchaseOrder.xsd
http://xmlns.oracle.com/xdb/documentation/purchaseOrder.xsd">
<PONum>1001</PONum>
<Company>IBM</Company>
<Item>
<Part>DB2 v9 Set</Part>
<Price>2550</Price>
</Item>
<Item>
<Part>8i Doc Set</Part>
<Price>350</Price>
</Item>
</PurchaseOrder>'));
with the sqlplus the are no error
but insert with java jdbc:
SQLTEXT = "INSERT INTO mypurchaseorders VALUES(XMLType(?))";
String xmldoc= "<PurchaseOrder"+
"xmlns='http://xmlns.oracle.com/xdb/documentation/purchaseOrder.xsd'" +
"xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'" +
"xsi:schemaLocation= 'http://xmlns.oracle.com/xdb/documentation/purchaseOrder.xsd'"+
"'http://xmlns.oracle.com/xdb/documentation/purchaseOrder.xsd'>"+
"<PONum>1001</PONum>"+
"<Company>IBM</Company>"+
"<Item> "+
"<Part>DB2 v9 Set</Part>"+
"<Price>2550</Price>"+
"</Item>"+
"<Item>"+
"<Part>8i Doc Set</Part>"+
"<Price>350</Price>"+
"</Item>"+
"</PurchaseOrder>";
pStmt.setString(1, xmldoc);
i got this error
java.sql.SQLException: ORA-31011: XML parsing failed
ORA-19202: Error occurred in XML processing
LPX-00240: element-start tag is not well formed
