Oracle.xdb.XMLType extract function
I have an external java program that connect to the database using a thick connection so I can use the methods extract and existsNode available with the XMLType from oracle.xdb.XMLType.
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
conn = DriverManager.getConnection(jdbc:oracle:oci8:@,"user","pwd");
It works fine from the program. When I load the java function in the SQL database I use the default connection
conn = DriverManager.getConnection("jdbc:default:connection:");
and the extract function gives the error java.sql.SQLException.
Is there a way to define the native connection as thin or thick because that was the error I was getting from the client program when I was using thin connection
Thanks

Error Missing class: oracle.xdb.XMLType with xdb.jar in JDeveloper 10.1.3
I am using JDeveloper 10.1.3 and get the following error when executing the web service proxy with my call to the web service( this web service is using class OracleXMLSave with method insertXML):
I have included the xdb.jar in my project properties libraries of the web service project and added a file group with xdb.jar to the properties of the webservices.deploy. What else needs to be done? This worked in JDeveloper 10.1.2.
THE ERROR after running proxy in log window:

actually you increment the index

which means you never have an index of 0 but always start with 1

How do I get unicode characters out of an oracle.xdb.XMLType in Java?
The subject says it all. Something that should be simple and error free. Here's the code...
String xml = new String("<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<x>\u2026</x>\n");
XMLType xmlType = new XMLType(conn, xml);
conn is an oci8 connection.
How do I get the original string back out of xmlType? I've tried xmlType.getClobVal() and xmlType.getString() but these change my \u2026 to 191 (question mark). I've tried xmlType.getBlobVal(CharacterSet.UNICODE_2_CHARSET).getBytes() (and substituted CharacterSet.UNICODE_2_CHARSET with a number of different CharacterSet values), but while the unicode characters are encoded correctly the blob returned has two bytes cut off the end for every unicode character contained in the original string.
I just need one method that actually works.
I'm using Oracle release 11.1.0.7.0. I'd mention NLS_LANG and file.encoding, but I'm setting the PrintStream I'm using for output explicitly to UTF-8 so these shouldn't, I think, have any bearing on the question.
Thanks for your time.
Stryder, aka RalphI created analogic test case, and executed it with DB 11.1.0.7 (Linux x86), which seems to work fine.
Please refer to the execution procedure below:
* I used AL32UTF8 database.
1. Create simple test case by executing the following SQL script from SQL*Plus:
connect / as sysdba
create user testxml identified by testxml;
grant connect, resource to testxml;
connect testxml/testxml
create table testtab (xml xmltype) ;
insert into testtab values (xmltype('<?xml version="1.0" encoding="UTF-8"?>'||chr(10)||'<x>'||unistr('\2026')||'</x>'||chr(10)));
-- chr(10) is a linefeed code.
commit;
2. Create QueryXMLType.java as follows:
import java.sql.*;
import oracle.sql.*;
import oracle.jdbc.*;
import oracle.xdb.XMLType;
import java.util.*;
public class QueryXMLType
public static void main(String[] args) throws Exception, SQLException
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
OracleConnection conn = (OracleConnection) DriverManager.getConnection("jdbc:oracle:oci8:@localhost:1521:orcl", "testxml", "testxml");
OraclePreparedStatement stmt = (OraclePreparedStatement)conn.prepareStatement("select xml from testtab");
ResultSet rs = stmt.executeQuery();
OracleResultSet orset = (OracleResultSet) rs;
while (rs.next())
XMLType xml = XMLType.createXML(orset.getOPAQUE(1));
System.out.println(xml.getStringVal());
rs.close();
stmt.close();
3. Compile QueryXMLType.java and execute QueryXMLType.class as follows:
export PATH=$ORACLE_HOME/jdk/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export CLASSPATH=.:$ORACLE_HOME/jdbc/lib/ojdbc5.jar:$ORACLE_HOME/jlib/orai18n.jar:$ORACLE_HOME/rdbms/jlib/xdb.jar:$ORACLE_HOME/lib/xmlparserv2.jar
javac QueryXMLType.java
java QueryXMLType
-> Then you will see U+2026 character (horizontal ellipsis) is properly output.
My Java code came from "Oracle XML DB Developer's Guide 11g Release 1 (11.1) Part Number B28369-04" with some modification of:
- Example 14-1 XMLType Java: Using JDBC to Query an XMLType Table

Trying to get UTF-8 data in and out of an oracle.xdb.XMLType
I need to be able to put unicode text into an oracle.xdb.XMLType and
then get it back out. I'm so close but it's still not quite working.
Here's what I'm doing...
// create a string with one unicode character (horizontalelipsis)
String xmlString = new String(
"<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" +
"<utf8>\n" +
" <he val=\"8230\">\u2026</he>\n" +
"</utf8>\n");
// this is an oci8 connection
Connection conn = getconnection();
// this works with no exceptions
XMLType xmlType = XMLType.createXML(conn, xmlString);
// this is the problem here - BLOB b does not contain all the bytes
// from xmlType. It seems to be short 2 bytes.
BLOB b = xmlType.getBlobVal(871);
String xmlTypeString = new String(b.getBytes(1L, (int) b.length()), "UTF-8");
PrintStream out = new PrintStream(System.out, true, "UTF-8");
out.print(xmlTypeString);
out.close();
What I get from this is this...
<?xml version="1.0" encoding="UTF-8"?>
<utf8>
<he val="8230">[utf-8 bytes]</he>
</utf8
In the above, [utf-8 bytes] represents the correctly encoded UTF-8 bytes that
were returned. But the output is missing the final closing bracket and the
newline at the end. It seems that no matter what second argument I give b.getBytes(),
it always returns the above. Even
It seems that this code...
BLOB b = xmlType.getBlobVal(871);
always returns a BLOB that contains a few bytes short of what it should contain.
What am I doint wrong? I'm sure I'm missing something here.
Thanks much for your help.
Here's info about the environment I'm working in.

Hi,
I am developing simple java class to try xsu.
I am using jdev 10.1.2.1.
I have done java class to generate xml using OracleXMLQuery.
It works fine.
I have done java class to save data from xml using OracleXMLSave.
It doesn't work!
The code is simple:
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:db10g2","hr","hr");
OracleXMLSave sav = new OracleXMLSave(conn, "DEPARTMENTS");
sav.insertXML(sav.getURL("file://c:/xmldb/insertDEPT.xml"));
sav.close();
during runtime at line "sav.insertXML(sav.getURL("file://c:/xmldb/insertDEPT.xml"));"
I got an exception:
java.lang.NoClassDefFoundError: oracle/xdb/XMLType
at model.TESTXML_2.main(TESTXML_2.java:20)
Exception in thread "main" Process exited with exit code 1.
Jdev has access to all jars in ORACLE_HOME\LIB.
What is wrong ?
I don't know where I can find such package oracle.xdb.

Where can i find oracle.xdb.XMLType?
Hello all!
Plz someone can help me?
Thx very much!Hi,
You cand find it in oracle.xdb package.
For this you need to download the Oracle XDK.
You can download Oracle XDK for java @

Oracle xdb xmltype escape character
Hi to all, my name is Gianluca.
I have a question to ask.
we are developing a web application with two two different environment, one of development and another one of test.
In each of this is installed Oracle Database 10g Enterprise Edition Release 10.2.0.3.0.
In development environment if i execute an xdb query from client like sqlplus or toad the ' character is not escaped and the query results is something like this:
SQL> select * from pippo;
DATI_XML
<xml>societa'</xml>
In test environment if i execute the some query the result is:
SQL> select * from pippo;
DATI_XML
<xml>societa'</xml>
What is the cause of the different behavior?
Thanks in advantage.Thank you very match for your reply.

Query Oracle 9i xmltype tables
Hi,
I have created a table of xmltype and loaded a large xml document of size ~47 MB.
I wish to execute the following query on the table(OracleBench_No_Schema) using Oracle thin driver.
select extract(value(X), '//eNest[@aSixtyFour=2]')
from OracleBench_No_Schema X;
can you provide me with a skeleton code for running such queries using a java program?
thanks in advance.
DayalHi ,
java version 1.4.2
I am using oracle jdbc drivers for java 1.4

This is the code that I am currently using...
import java.util.Iterator;

String query = "select extract(value(X), '//eNest[@aSixtyFour=2]').getClobVal() \n" +
"from OracleBench_No_Schema X";

Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@138.87.169.78:1521:itkora2","dmuruku","dmuruku");
OraclePreparedStatement stmt = (OraclePreparedStatement) conn.prepareStatement(query);
System.out.println("Executing Query...");
OracleResultSet orset = (OracleResultSet)stmt.executeQuery();
System.out.println("Query Executed....");
while(orset.next())
oracle.sql.CLOB clob = orset.getCLOB(1);
Reader reader = clob.getCharacterStream();
//----------------These set of lines when included in the program are causing protocol violation---------
StringBuffer clobBuffer = new StringBuffer();
char[] buffer = new char[1024];
int readCount;
while ( (readCount = reader.read(buffer)) != -1)
{ clobBuffer.append(buffer, 0, readCount); }
//This included...protocol violation
conn.close();
catch(Exception ex)
System.out.println(ex.toString());
As I mentioned the lines of code between the two commenting lines when Included in the program are causing a protocol violation.
(java.io.IOException: Protocol Violation).
Is there any other way to read data from a Reader Object into a file or to display it on the console output?
please advise

Java Stored Procedures + oralce.xdb.XMLType + initxdbj.sql
In order to use XMLType object in java stored procedures, I need to import oralce.xdb.XMLType package. I got compiler error saying "Class oracle.xdb.XMLType not found" (See List1).
I check my installed package, sure enough these is no "oracle/xdb/XMLType" or any xdb related one. (See list2) This surprises me since my 9i/Solaris installation was successful and spotless one.
The 9i App Dev - XML doc states that script $ORACLE_HOME/rdbms/admin/initxdbj.sql could install that package. (See List3) The fact is no way this script could be found from Oracle901/Solaris8 or Oracle901/NT installations.
If java program moved to client and included xdb_g.jar in CLASSPATH, then it is fine as Doc declares. It just failed to compile in server as stored procedures.
Please help, Thanks.

Installing and using oracle.xdb.XMLType class
The oracle.xdb.XMLType is available in the xdb_g.jar file in the ORACLE_
HOME/rdbms/jlib where ORACLE_HOME refers to the Oracle home directory.
Using oracle.xdb.XMLType inside JServer:
This class is pre-loaded in to the JServer and is available in the SYS schema.
It is not loaded however, if you have upgraded your database from an earlier
version. If you need to upload the class into the JServer, you would need to run the
initxdbj.sql file located in the ORACLE_HOME/rdbms/admin directory, while
connected as SYS.
Using oracle.xdb.XMLType on the client:
If you need to use the oracle.xdb.XMLType class on the client side, then ensure that
the xdb_g.jar file is listed in your CLASSPATH environment variable.
===================================================================== -
Slow to convert Oracle 11g XMLType into Java String or Document
After retrieving a result set from an Oracle 11g database, it takes roughly 75 seconds to convert the XMLType (this is a structured XML Storage, registered with an xsd) into either a java String or Document. I'm using Java 1.6, have the xdb.jar and xmlparserv2.jar
This xsd is <100 lines and the xml document is also <100 lines.
Sample code:
oracle.xdb.XMLType xml = oracle.xdb.XMLType.createXML((oracle.sql.OPAQUE)rset.getObject("XMLDATA"));
the other way, but still took just as long:
XMLType xml = (XMLType)rset.getObject("XMLDATA");
xml.getStringVal();
or
org.w3c.dom.Document doc = xml.getDocument();
either way of the above ways takes just as long.If I put this value into the database table, I can
see only the date. Time part is missing. Is this the
problem with java.sql.Date or Oracle datatype Date?This is not a problem, this is the defined behaviour of the Date type. RTFAPI and have a look at Timestamp, while you're at it. -
XML escape sequences for brackets and xmltype.extract
G'day gang, I'm hoping somebody would be kind enough to help me with the following query please.
I have a web service that is returning the following XML stream into an XMLType in the database:
<OutOfStockAdviceResponse xmlns="http://abc.org/abcWebServices">
<OutOfStockAdviceResult>
& lt;Response& lt;ResponseCode& gt;0& lt;/ResponseCode& gt;
& lt;ResponseMessage& gt;Successful& lt;/ResponseMessage& gt;
& lt;/Response& gt;
</OutOfStockAdviceResult>
</OutOfStockAdviceeResponse>You'll note the & lt; and & gt; characters (note to display these strings in OTN I've had to add a space between the & and the lt; or gt;. The spaces don't actually occur in the real XML data coming back).
What's odd about this XML stream coming back is it is mixing the use of the XML angle brackets with the escape character equivalents (eg. & lt; and & gt;) half way through the XML stream. Is this valid for an XML stream to do this? Any idea what would cause this? Is it possible the source is creating 2 separate XML streams using different character sets and then concatenating them to get this result?
The reason I'm asking is I'm attempting via PL/SQL to extract the ResponseCode and ResponseMessage tags with the following code:
v_response_code := XMLType.extract(v_response,
'/OutOfStockAdviceResponse/OutOfStockAdviceResult/Response/ResponseCode/text()',
'xmlns="http://abc.org/abcWebServices"').getnumberval;
v_response_msg := XMLType.extract(v_response,
'/OutOfStockAdviceResponse/OutOfStockAdviceResult/Response/ResponseMessage/text()',
'xmlns="http://abc.org/abcWebServices"').getstringval;Both calls are failing with:
ORA-30625: method dispatch on NULL SELF argument is disallowedCan anybody point me in the right direction for solving this issue? Is there a way to get the xmltype.extract function to recognize the different character encoding schemes (if they do indeed actually exist)?
Any help appreciated.
CM.
PS. Apologize for the weak subject line.Chris
Since that Serviceis actually returning the escaped representation of '<' and '>' inside OutOfStocAdviceResult, the XML Parser considers that whole block of text to be simply a text node child the parent element, not valid XML. Hence the result of your XPath expressions is null and you get the ORA-30625 when you try to invoke the getNumberVal() and getStringVal() methods, which is the PL/SQL equivilant of a Java Null Pointer Exception.
You can solve it as follows...
set define off
set serveroutput on
declare
v_response xmltype;
v_response_code number(4);
v_response_msg varchar2(64);
v_xmltext varchar2(256);
v_OutOfStockResponse xmltype := xmltype(
'<OutOfStockAdviceResponse xmlns="http://abc.org/abcWebServices">
<OutOfStockAdviceResult>
& lt;Response& gt;& lt;ResponseCode& gt;0& lt;/ResponseCode& gt;& lt;ResponseMessage& gt;Successful& lt;/ResponseMessage& gt;& lt;/Response& gt;
</OutOfStockAdviceResult>
</OutOfStockAdviceResponse>');
begin
select extractValue(v_OutOfStockResponse,'/OutOfStockAdviceResponse/OutOfStockAdviceResult','xmlns="http://abc.org/abcWebServices"')
into v_xmltext
from dual;
dbms_output.put_line('Text = ' || v_xmlText);
v_response := xmltype(v_xmltext);
v_response_code := v_response.extract('/Response/ResponseCode/text()').getnumberval();
v_response_msg := v_response.extract('/Response/ResponseMessage/text()').getstringval();
dbms_output.put_line('Code = ' || v_response_code);
dbms_output.put_line('Msg = ' || v_response_msg);
end;Note that like you I had to insert space characters between in the 'lt' and 'gt' escape sequences...
When this is run you get the following
SQL> set define off
SQL> set serveroutput on
SQL> --
SQL> declare
2 v_response xmltype;
3 v_response_code number(4);
4 v_response_msg varchar2(64);
5 v_xmltext varchar2(256);
6 v_OutOfStockResponse xmltype := xmltype(
7 '<OutOfStockAdviceResponse xmlns="http://abc.org/abcWebServices">
8 <OutOfStockAdviceResult>
9 & lt;Response& gt;& lt;ResponseCode& gt;0& lt;/ResponseCode& gt;& lt;ResponseMessage& gt;Successful& lt;/ResponseMessage& gt;& lt;/Response& gt;
10 </OutOfStockAdviceResult>
11 </OutOfStockAdviceResponse>');
12 begin
13 select extractValue(v_OutOfStockResponse,'/OutOfStockAdviceResponse/OutOfStockAdviceResult','xmlns="http://abc.org/abcWebServices"')
14 into v_xmltext
15 from dual;
16 dbms_output.put_line('Text = ' || v_xmlText);
17 v_response := xmltype(v_xmltext);
18 v_response_code := v_response.extract('/Response/ResponseCode/text()').getnumberval();
19 v_response_msg := v_response.extract('/Response/ResponseMessage/text()').getstringval();
20 dbms_output.put_line('Code = ' || v_response_code);
21 dbms_output.put_line('Msg = ' || v_response_msg);
22 end;
23 /
Text =
<Response><ResponseCode>0</ResponseCode><ResponseMessage>Successful</ResponseMes
sage></Response>
Code = 0
Msg = Successful
PL/SQL procedure successfully completed.
SQL>Basically we extract the encoded text using extractValue() which will de-escape the escapted characters and then create a new XMLType which we can operate on
