New ODI User having trouble creating an XML Data Source...

Question

How's everyone doing? I'm new to the Oracle Data Integrator software. My goal is to take an XML message, do a bunch of mappings/constraints/etc. and integrate the appropriate data into an Oracle database. Seems like ODI is good for the job, but I'm running into some issues setting up the actual XML source file.
I followed this guide: [ODI XML to Database Transformation|http://www.oracle.com/technology/obe/fusion_middleware/ODI/ODIXML_to_DB_Transform/ODIXML_to_DB_Transform.htm], which was helpful, but since it used example XML files it did not go into how to use your own custom XML file.
Let me start off by sharing the XML file I'm attempting to import:
<?xml version="1.0" encoding="UTF-8"?>
<Money xmlns="http://xxxxx.oracle.com/schema/Money"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xxxxx.oracle.com/schema/Money file:/C:/OraHome_1/oracledi/demo/xml/Money.xsd">
    <MoneyID>MoneyID0</MoneyID>
    <ContractID>ContractID0</ContractID>
    <EffectiveDate>2006-05-04T18:13:51.0Z</EffectiveDate>
    <MessageDate>2006-05-04T18:13:51.0Z</MessageDate>
    <ReversalIndicator>false</ReversalIndicator>
    <PriorMoneyID>PriorMoneyID0</PriorMoneyID>
    <Amount>0</Amount>
    <MoneyType>0</MoneyType>
    <ExchangeDetails>
        <CostBasis>0</CostBasis>
        <ExchangeType>0</ExchangeType>
        <MEC>false</MEC>
        <LoanAmount>0</LoanAmount>
    </ExchangeDetails>
</Money>Pretty straightforward I'd say. Note that the XSD file it references DOES exist in that directory, so everything should be fine. So I go into Topology, select the "Physical Architecture" tab, right click "XML", click "Insert Data Server". I name my file "XML_MONEY", select the JDBC tab, and fill in the following fields:
JDBC Driver: com.sunopsis.jdbc.driver.xml.SnpsXmlDriver
JDBC Url: jdbc:snps:xml?f=../demo/xml/Money1.xml
When I hit "Test", it gives me this annoying message:
java.sql.SQLException: Could not generate the DTD because the file could not be created. Verify that you have write permission in the directory.
I have no idea why. I definitely have permissions to write to that directory.
I played around some more, and removed the junk at the top of the XML file, leaving the file with JUST XML tags. Now I get this error:
java.lang.ArrayIndexOutOfBoundsException: 1
What does this mean? I'm confused why this would be happening, because I a couple of days ago when I was playing around with a dummy XML file (with just tags) it connected just fine.
If anyone can lend a hand I'd greatly appreciate it. I'm probably missing something stupid, so feel free to yell at me.
Thanks!!

Answer 1

hi , i will try to help u out....lets take a simple example
create your own xml for example
<pre>
<?xml version="1.0" encoding="UTF-8"?>
<ROWSET>
<ROW>
<ENAME>SCOTT</ENAME>
<SAL>15000</SAL>
<LOC>INDIA</LOC>
</ROW>
<ROW>
<ENAME>ROCK</ENAME>
<SAL>25000</SAL>
<LOC>USA</LOC>
</ROW>
</ROWSET>
After that go to Topology manager create a data server in xml technology for example "EMPLOYEE"
JDBC DRIVER : com.sunopsis.jdbc.driver.xml.SnpsXmlDriver
JDBC URL : jdbc:snps:xml?f=C:/EMP.xml&s=EMP01
Test it you will get Successful connection message.
After getting this message apply the settings.Physical Schema window will pop up there give Schema as EMP01,Work Schema as EMP01 then in the context tab
create a context and give the logical schema name it can be any name..here i am giving the my logical schema name as EMP01.Apply the changes.
Create a model
1.In Definition tab give the model name
select Technology as XML
Logical Schema as EMP01
2.In the Reverse tab select the context which u have created in the topology manager
3.In the Selective Reverse tab reverse all the tables.
in the model you will be getting 2 datastores ROWSET,ROW
Create an Interface
Drag the ROW datastore into source
I have crated EMP_TEST table in my oracle database Ename,Sal,Loc as columns and reversed it so that i can use EMP_TEST table as my target table
Drag the EMP_TEST table in the Target datastore map the columns
select IKM as SQL toSQL Append execute the interface the data in the xml will be loaded in to EMP_TEST table.
</pre>
Hope this helps u
Thanks,
