Xpath query return problem

Hi;
I want to load xml file into the database oracle 9.0.2 using Oracle XML DB Utilities Package on "http://otn.oracle.com/sample_code/tech/xml/xmldb/xdbutilities/XMLDB_Utilities_Overview.htm"
I have a schema like:
<xs:element name="catalog">
<xs:element name="catalog">
<xs:complexType xdb:SQLType="OBJ_CATALOG">
<xs:sequence>
<xs:element name="category">
<xs:complexType xdb:SQLType="OBJ_CATEGORY">
<xs:sequence>
<xs:element name="product">
<xs:complexType xdb:SQLType="OBJ_PRODUCT">
<xs:sequence>
<xs:element name="name" type="xs:string"/>
and my file include:
[i]<catalog>
<category name="books">
<product id="1" keywords="yasanti, Latin Amerika" >
<name>Gunes Topraklari</name>
</product>
</category>
<category name="CDs" >
<product id="5" keywords="music, easy listening" >
</product>
</category>
I can use xpath query like
select extract(value(x), '/catalog/category[@name="books"]').getstringval() from product_table x
and get result but I can not take any data about product elements with queries such that
select extract(value(x), '/catalog/category[@name="books"]//name/text()').getstringval() from product_table x
Does anyone has an idea about this problem?
Thanks a lot.
Alper.

ah ok , I was confused with this q:= q||'AND (ab.status = '''||list_status(i)||'''';I think I get it now
basically stop the string and write double quotes before the variable
'AND (ab.status = ' + ''||list_status(i)||'' + ''No, more like "wherever I want a single quote within a string, I put two single quotes instead and that tells oracle it's a quote and not the end of the string".
q:= q||'AND (ab.status = '''||list_status(i)||'''';

Human Workflow Task XPath query string returns multiple nodes.

I am looking for trouble shooting help for this error. I am no sure if it is a server or jdev issue.
I am running JDev version 10.1.3.3 and console version 10.1.3.1.0 locally.
General information on the BPEL process:
I have a temporary table in Oracle lite that I created items to be review by the user. I created a synchronous BPEL process. The first step in developing this process, I created the straight forward invoke the table to get the records, transform the records with a change the approve flag = "Y", and invoke the table to update the records. Works like a charm. I followed the online tutorial by dropping a human task after the transform, configured the parameters, setup the assignments, and moved the invoke to update table under the approved condition. If the table has only one record, the process runs great but if there are two records I get the following error message.
<selectionFailure xmlns="http://schemas.xmlsoap.org/ws/2003/03/business-process/"><part name="summary"><summary>XPath query string returns multiple nodes.
According to BPEL4WS spec 1.1 section 14.3, The assign activity part and query /ns3:TempItemCollection/ns3:TempItem/ns3:ItemNbr should not return multipe nodes.
Please check the BPEL source at line number "178" and verify the part and xpath query /ns3:TempItemCollection/ns3:TempItem/ns3:ItemNbr.
</summary>
</part></selectionFailure>
=================
The error occurs in the first assign of the Human task after the assign copies the fields for the title. I underlined line number 178.

Thank you for any help you can give me.

Here is how I solved this problem: I was told by the metalink folks that I should use the same verion of SOA console as jdev. So I went back to jdev 10.1.3.1. Rather than reading from the Oracle lite table, I dumped the table into a flat file. I read flat file and populated the workflow. Remember to set the 'messages in batch' flag in the file adapter to 1 and the number of records to skip to zero in the format builder for the flat file. The process now reads each record and creates an instance for that each record. In other words, if I have 8 records in my flat file, I will have 8 instances of the process running on the console. Thanks Jeremy for your help figuring this out.

Error: XPath query string returns multiple nodes

Hi all,
I am facing issue with the assign activity.
Error message:

We are using SOA 11.1.1.3 version.
Any pointers on this?
Thanks in advance

Hi-
This is because you are have multiple nodes either in source or target XML.
My guess is some nodes of your XML might be repeating (means a single element/node has multiple values). Can you please check that or please post your XML here.

XPath Namespace resolver problem

I've trying to run a simple XPath query
//z:rowin Java against against the following XML.
<?xml version="1.0" encoding="utf-8"?>
<test xmlns:rs="urn:schemas-microsoft-com:rowset"
     xmlns:z="#RowsetSchema">
<rs:data>
<z:row>XX</z:row>
</rs:data>
</test>I've written my own namespace prefix resolver, and also used the NamespaceContext object at the end of this example [http://www.ibm.com/developerworks/xml/library/x-nmspccontext/index.html?ca=drs-|http://www.ibm.com/developerworks/xml/library/x-nmspccontext/index.html?ca=drs-]
The problem is that I also get the following error:
javax.xml.transform.TransformerException:A location step was expected following the '/' or '//' token.
The problem is the *#* sign in the xmlns:z="#RowsetSchema". If I rename the namespace to be just xmlns:z="RowsetSchema" then it works fine.
Help, this is driving me mad.
TIA
Ian

Copying Variables in BPEL using XPath Query

Hi,
I am new to BPEL and i want to know if it is possible to copy data from one variable to another using XPath Query in the <from> <to> tags, when the two variables are of different message types.
I am trying to create a sample BPEL that would receive a String through the receive tag tied to one partner link (WSDl) and then invoke a different webservice using the <invoke> tag tied to another partner link (WSDL) by passing the received variable.
I have pasted the BPEL File and the two WSDl files involved.
My Issue is that when I send a soap request to the BPEL, it is passed as null to the webservice invoked.
Probably because the copy tags don't work.
Please help.

Hi,
Yes, it very much is possible.
Xpath query provides a lot many data type conversion functions(string to int, string to date etc), which can be used in copying variables.
thanks

XML attributes makes my query return no rows

Hello everyone,
I've an odd problem.
I'm querying some XML, but the attributes in one of the tags make my query return no rows; if I remove the attributes, then the query works as expected.
The XML is below; it's the attributes in the Report tag that cause the issues:
<result errorCode="0">
     <return>
          <Report
               xsi:schemaLocation="Items_x0020_status_x0020_information http://******-****/ReportServer?%2FReports%2FContent%20Producer%20Reports%2FItems%20status%20information&rs%3AFormat=xml&rc%3ASchema=True"

                ) a;I've tried stripping out the attributes in the tag, which does work, but some of the XML I'm expecting back may be quite large (many records), so that caused issues in itself. I'd rather deal with it and not mess with the XML itself if possible.
Any help would be hugely appreciated!
Thank you very much in advance.

Creating a directory via a jsp page sql query return

Is it possible to create a directory based on the results of a sql query?
i.e.
My sql query returns application number 1234 for a building application (BC for short).
Is it possible to create a directory /BC/1234
It is then proposed to use an iframe to look into the directory so users can place and access scanned documents which are captured during the approval process.
If so how?
An example would be great.
Jason

Sorry hope your still around I've been away for a while. We've created a samber share to the file server where the documents are stored and mounted it within the web file directory. It works ok if there is an existing directory but if there isn't we want it to be created when the page looks for the folder. I've done this with an asp page it basically did a directory exist test first then create folder if it didn't. The problem is can't find an example of how to do the directory exist test then directory create syntax so an example of both would be great

Variable Picker generates invalid XPath query

This one seems to be a bug:
When declaring a variable of type "element" (not "messageType") and accessing the variable with the Variable Picker from within the assign assistant, i.e. the following line ist generated:
bpws:getVariableData("testVar","","/tns:TaskMgrTestCaseRequest/tns:input")
The BPEL process can be validated and deployed without an error.
At runtime the following exception is generated:
XPath expression failed to execute.
Error while processing xpath expression, the expression is "bpws:getVariableData("testVar", "", "/tns:TaskMgrTestCaseRequest/tns:input")", the reason is XPath expression failed to execute.
Error while processing xpath expression, the expression is "", the reason is Unexpected ''.
Please verify the xpath query.
Please verify the xpath query.
When working with variables of type messageType, there is no problem. (So I declared a messageType to each element type ...)

Thanks for the heads up. We will try to kill this bug in the 0.97 release. -Edwin

Query parameter problem

I'm using the value selected in a dropdown list (20 separate values) as the where clause in a query to populate a table:
dataElementsTableModel.setObject(1, xactionDropdown.getValue());
dataElementsTableModel.execute();
This works OK for most of the values in the dropdown list, but not all of them. If I cut and paste the table query from Creator to SQL*Plus and run it with any of the list values, the query returns the correct number of rows. Has anyone else run into this problem, and maybe has a solution?

I noticed that when the data table is empty after selecting one of the values from the dropdown list, the table WILL BE populated if I refresh the page with F5. The behaviour is consistent, i.e., it's always the same dropdown values which cause or don't cause the data table to be populated.

Applying sort to a query returned by a stored procedure

I am looking for some advice on the best approach for applying a dynamic sort to a query returned by a stored procedure.
We have a stored procedure that has 3 inputs fields which are used to specify sort columns and it has an additional 3 fields to indicate if the corresponding input column is to be sorted in ascending or descending order. We presently accomplish this by using dynamic SQL in the procedure but this approach has some drawbacks. Ideally we would like these queries to compile just like any other cursor. We have tried using decodes but this does not seem practical or easy to maintain.
This procedure is used by a web application that allows the user to click on a column header to specify their sort preference. The previous sort selection becomes the second sort field and the one before that the third.
Your advice is much appreciated!

I see, so you want to be able to sort by "name desc, age asc, salary asc", for example.
there is no built in option. it's either dynamic sql, or decodes.
the decodes could still work, with only 6 lines, but the problem is handling mixed data types. I'll stick with sort col of 1=name (char), 2=number_col, 3=date_col
order by
decode(sort_order1, 'A', decode (sort_col1, 1,name_col, 2,to_char(number_col,'9999999999.00000'), 3,to_char(date_col,'yyyymmddhh24miss'), 'X'),'X'),
decode(sort_order1, 'D', decode (sort_col1, 1,name_col, 2,to_char(number_col,'9999999999.00000'), 3,to_char(date_col,'yyyymmddhh24miss'), 'X'),'X') DESC,
decode(sort_order2, 'A', decode (sort_col2, 1,name_col, 2,to_char(number_col,'9999999999.00000'), 3,to_char(date_col,'yyyymmddhh24miss'), 'X'),'X'),
decode(sort_order2, 'D', decode (sort_col2, 1,name_col, 2,to_char(number_col,'9999999999.00000'), 3,to_char(date_col,'yyyymmddhh24miss'), 'X'),'X') DESC,
decode(sort_order3, 'A', decode (sort_col3, 1,name_col, 2,to_char(number_col,'9999999999.00000'), 3,to_char(date_col,'yyyymmddhh24miss'), 'X'),'X'),

Coldfusion Query Delay Problem

Folks we are having some intermittent problems with our
application web servers.
We are using coldfusion to serve data from Oracle databases.
SELECT statements only, no updating of the database is done. The
coldfusion application server and the oracle database server are
seperate servers,
The problem we are having is as follows.
When the user opens the app for the 1st time a query is run
to work out what access level they have. 95% of the time the query
is instant. We have been logging this using getticktick()
often the time taken is 0ms we also see 16ms and 31ms. The query
returns
1 row with 1 field in it to size of data returned is not an
issue.
Occasionally we get this query reportedly taking between 5
and 120 seconds using gettickcount() either side of it.
We turned on some logging at the Oracle end and this reported
that EVERY time a query of this type it is taking absolutely no
time all.
Our next port of call was the network. We have sniffed
packets between the coldfusion server and the oracle server.
We managed to trap one of the requests where the response
time is slow and the scenario was as follows :
1. Coldfusion -> Oracle. Hello i've got some work for you
to do. Completed in millisenconds
2. Oracle -> Coldfusion. Acknowledged, Yes what is it?
Completed in millseconds.
3. Coldfusion -> Oracle Acknowledged......... delay of 17
seconds (delay times vary)..... it's this query
4. Oracle -> Coldfusion. Here are your results. completed
in milliseconds
5. Coldufsion -> Oracle. Acknlowledged. completed in
millseconds.
So it appears that internally within coldfusion a delay is
occuring as the database and the network have been eliminated.
The delay time is never the same and can range from a couple
of seconds to over a minute. The times of day that these delays
occur at is not uniform.
The server is busiest between 0800 and 1700. But this server
is NOT under heavy load at all, it is however query intensive. It
is up 24 hours a day and there is a constant user base.
We have tuned all our queries and cached them as best we can.
However i'm not sure how much this helps as we get delays on
queries we know are performant.
We are currently upgrading one of our servers to CF8 using
oracle thin jdbc drivers rather than the odbc to see if this makes
a difference.
If anyone has previous experience of this or knows of
anything settings we need to tweak at a java level that would be
great.
Spec of what we are running is as below :
Windows 2003 Server
Coldfusion MX 7.0.2 Standard
Oracle 10g ODBC Drivers
Any help gratefully received as the users are starting to get
fed up of having these delays for no apparent reason.

> 3. Coldfusion -> Oracle Acknowledged......... delay
> of 17 seconds (delay times vary)..... it's this query
Do you mind elaborating here?
It kind of appears as if there are two requests.
Meaning, is it just as correct to state it this way:
2. Oracle -> Coldfusion. Acknowledged, Yes what is it?
Completed in millseconds.
3. Coldfusion -> Oracle Acknowledged. it's this query.
delay of 17 seconds (delay times vary)
4. Oracle -> Coldfusion. Here are your results. completed
in milliseconds
If this is how it happened, then I would guess that
it's a database issue.
Or perhaps this is the more correct way to state it:
2. Oracle -> Coldfusion. Acknowledged, Yes what is it?
Completed in milliseconds.
3. Coldfusion -> Oracle Acknowledged. Completed in ???
4. Coldfusion -> Oracle it's this query. Completed in ???
5. Oracle -> Coldfusion. Here are your results. completed
in milliseconds
If this is how it happened, then I would think you
need to determine which step took 17 seconds.

Finder query return type..?

I'm using a session bean ProcessBean and an entity bean AlarmBean....
where one of functions processor() of ProcessDataBean is like......
processor()
println(.a..);
println(..b.);
correlate();
println(.c..);
And correlator() is like:-
correlator()
println(..d.);
AlarmBeanLocal l = finder query();
println(.e..);
if(l != null)
println(.m..)
else
println(.n..)
Finder query returns the reference to the entity bean's local interface.......and depending on whether find is successful or not....I've to print m or n....
Now the problem is whenever find is successful.......e, then m and then c gets printed......
but when finder query is not successful, e and n doesn't get printed....and directly c gets printed...it means finder query is directly returning control to the previous function(processor where c is getting printed) .......
I'm not getting whr. is the problem....
in the condition l != null......?
Plz. help me out...
All the declarations in local and home interfaces and ejb-jar is correct.......and my jar file is deployed successfully.....but the output is not correct.....

Hi Swati,
Assuming ur finder returns a Single-object
Single-object finder method may return a null value . If result set of query consists of a single null value, container must return null value as result of method. If resultset of a query for a single-object finder method contains more than one value (whether non-null, null, or a combination), container must throw FinderException from finder method. If result set of query contains no values, container must throw ObjectNotFoundException.

CAML Query returning all items with date condition

HI,
I have a problem doing a query with CAML over the elements of a calendar in SharePoint 2013
I just want to retrieve all items, which have been modified on a particular date. But below query returns all items from the Calendar.
Any suggestion how to get specific items from the calendar. The same issue exists for start date and end date.
var oWebsite = clientContext.get_web();
this.collList = oWebsite.get_lists();
var camlQuery1 = new SP.CamlQuery();
camlQuery1.set_viewXml(
'<query><Where>'+
'<Eq>'+
'<FieldRef Name=\'Modified\' IncludeTimeValue=\'TRUE\'/>' +
'<Value Type=\'DateTime\'>2014-02-24T12:00:00Z</Value>'+
'</Eq>'+
'</Where></query>');
this.collListItem1 = oList.getItems(camlQuery1);
clientContext.load(collListItem1);

Firstly try to make this change in your query and see if that helps
camlQuery1.set_viewXml(
'<View><Query><Where>'+
'<Eq>'+
'<FieldRef Name=\'Modified\' IncludeTimeValue=\'TRUE\'/>' +
'<Value Type=\'DateTime\'>2014-02-24T12:00:00Z</Value>'+
'</Eq>'+
'</Where></Query></View>');
