JDBC 'Query Multiple to XML' throwing NullPointerException on LC Server

Hi all...
It seems that any attempt to perform a jdbc access from a deployed LCA (my process at this point only contains the JDBC 'query multiple to xml' operation) results in the following exception on the LC server (see below). The query and xml generation all seem to work ok from the Workbench. I can mail the lca upon request. Thanks.

Using Query Multiple to XML

Hi,
I am trying to use the service Query Multiple to XML which Queries the database using a SQL statement and returns the result set as XML data.
I configure and test (using test functionality in this service to see what is gonig on) this service in my workflow. As the result of this test, I saw that this wuery returns a piece of data in xml format like this :
 Özlem Aksel
 Cihan Aydın
 Fatih Büyüktaş
 Melik Akyıldız
 Aydın Türkdoğan
In Livecycle es samples, there is a sample about multiple query to xml,
but this sample just show that this service returns XML element. But, does not show, how to use it in forms.
My aim is, populating a dropdown list in my form, with the data returned by this query. Can anyone tell me how can use this data to populate my dropdown list?
Thanks in advance
Best regards
Cihan Aydın

Hi, I found a solution for my problem. I try to explain it below : In order to get user names and fill them to a combo,I use a simple form which consist of only a combo of user names with the following xml schema : <?xml version="1.0" encoding="UTF-8"?> <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <xsd:annotation> <xsd:documentation xml:lang="en"> MultipleSql deneme </xsd:documentation> </xsd:annotation> <xsd:element name="UserListApp" type="userlistFormType"/> <xsd:complexType name="userlistFormType"> <xsd:sequence> <xsd:element name="userList" type="userlistType"/> <xsd:element name="tempdata" type="xsd:string" /> </xsd:sequence> </xsd:complexType> <xsd:complexType name="userlistType" > <xsd:sequence> <xsd:element name="users" type="user" minOccurs="1" maxOccurs="unbounded" /> </xsd:sequence> </xsd:complexType> <xsd:complexType name="user" > <xsd:sequence> <xsd:element name="name" type="xsd:string" /> </xsd:sequence> </xsd:complexType> </xsd:schema> Then, in process design, I put an query to xml service with the following configuration : SQL stalement : SELECT commonname from edcprincipalentity where organization=? XML information : root Element name : userList repeating element names : users XML output : define a process variable of XML type (im my ex : xml_output) which returns : <userList> <users> <name type="VARCHAR">Fatih Büyüktaş</name> </users> <users> <name type="VARCHAR">Aydın Türkdoğan</name> </users> <users> <name type="VARCHAR">Özlem Aksel</name> </users> <users> <name type="VARCHAR">Cihan Aydın</name> </users> </userList> Then using a set value service, put this piesce of xml to form data /process_data/<FORM VARIBLE NAME>/object/data/xdp/datasets/data/UserListApp = /process_data/xml_output Then, in form, add this script to combo box's initialize event : var oUsersNode = xfa.data.UserListApp.userList; var oUsersNodeList = oUsersNode.resolveNodes("users[*].name"); for (var i = 0; i < oUsersNodeList.length; i++) { this.addItem(oUsersNodeList.item(i).value); } If you send your e-mail I can send you the complete example.

JDBC Querying Null Values

I'm using the JDBC Query Multiple Rows as XML to query an Oracle database. Many of the fields I'm querying are nullable and in fact some contain null values. I can't figure out why the JDBC component queries a null value as the string "null". I've tried to work with nvl() or replace() in my SQL statement, but I haven't got either of them to work.
I would assume someone else has run into this. Anyone have any advice on how to get around this?

I just found a solution that worked for my situation.
On the form being merged with the xml data, select the field(s) you want to hide the null value for.
Then go into the 'Field' tab in the 'Object' palette, click on the patterns button.
In the Data tab click 'Allow empty' and in the text box below it type
null
This should hide any null values from being displayed as 'null' on the form. This also works for numeric fields and date/time fields.

Query multiple XML files

Hi,
Is there another way of making queries in multiple different XML files other than using XQuery?
I use CremeVM for a CDC but it doesn't have desiredAssertionStatus() method in its Class.class so XQuery doesn't work.
Another option to solve it will be to execute multiple XPath expressions but not a good solution I think.
Any suggestions?

Thanks Curt,
just for others.... My Function for reading XML:-
let XmlImportedFile = (FilePath, FileName) =>
let
Source = Folder.Files(FilePath),
File = Source{[#"Folder Path"=FilePath,Name=FileName]}[Content],
ImportedXML = Xml.Tables(File)
in
ImportedXML
in
XmlImportedFile
then it's use to combine into a custom Column:-
let
Source = Folder.Files("C:\Users\Tim\Data\Education\Collect\XML files January 2014"),
InsertedCustom = Table.AddColumn(Source, "XmlImportedFiles", each XmlImportedFile([Folder Path],[Name])),
RemovedColumns = Table.RemoveColumns(InsertedCustom,{"Content", "Name", "Extension", "Date accessed", "Date modified", "Date created", "Attributes", "Folder Path"}),
#"Expand XmlImportedFiles" = Table.ExpandTableColumn(RemovedColumns, "XmlImportedFiles", {"Name", "Header", "School", "Pupils"}, {"XmlImportedFiles.Name", "XmlImportedFiles.Header", "XmlImportedFiles.School", "XmlImportedFiles.Pupils"})
in
#"Expand XmlImportedFiles"
thanks again and great blog post :-)
Thank you for you time folks!

Query multiple rows

Hi, need some help on XML and XSD.
say I have a table in the database with 3 columns: a, b, c
on my XDP form, I have a table, like a spreadsheet, with 3 columns too: x, y, z
and it has 10 rows.
I want to pre-fill the form with 10 rows of data,
so, in my Process's action profile,
I use JDBC's query multiple rows to get the first 10 records of my database table.
how do I put these 10 rows of data into the table on my form?
TIA for helping me.
Happy New Year!

Step1: Use SQL Query Multiple results as XML activity
Step2: Define the output of SQL activity to look similar to
<table>
 <row>row1 value</row>
 <row>row2 value</row>
 <row>row3 value</row>
 <row>row4 value</row>
 <row>row5 value</row>
 <row>row6 value</row>
 <row>row7 value</row>
 <row>row8 value</row>
 <row>row9 value</row>
 <row>row10 value</row>
</table>
Step3: arrange your forms fields (Table and rows) in the same way as mentioned above.

CreateEntityManagerFactory throws NullPointerException for ejb3 jse client

This question has been posted to the Toplink/jpa forum without any reply.
Dear experts!
I am trying to create a java standard edition client, to test outside the weblogic server, my ejb 3 entities, declared as shown in the following persistence.xml.
The java code follows also. I have read about some relevant bugs in eclipselink back in 2006, or 7 or 8 and mostly unanswered threads :
CreateEntityManagerFactory null pointer exception and
Returned null to createEntityManagerFactory about tomcat and oc4j.

Thank you for your reply!
The client now works correctly. It seems that the line
em = emf.createEntityManager(emProps);//
throws an exception when no argument is given for em = emf.createEntityManager();// emProps missing!
There was also a warning in jdev editor, about the line you mentioned:

Carry on with your good work!

JDBC query theme in a JSP page

Hi, everyone
I tried to write JDBC query theme in a JSP page at MapViewer, but it did not work.
The following is the codes.
1.JDBC theme in a map request in XML
<theme name="jdbc_theme_contour">
<jdbc_query
datasource="spatial10g"
jdbc_srid="8703"
spatial_column="geom"
render_style="C.RED">
Select geom from contour where time='01-JUL-07'
</jdbc_query>
</theme>
2. JDBC theme in a JSP request.
"<theme name=\"jdbc_theme_contour\" >\n" +
" <jdbc_query \n" +
" jdbc_srid=\"" + srid + "\"\n" +
" datasource=\"" + dataSource + "\"\n" +
" spatial_column=\" geom \"\n" +
" render_style=\"C.RED\" >\n" +
" SELECT geom from contour where time='01-JUL-07' \n" +
" </jdbc_query> \n" +
" </theme> \n" +
I do not know whether the second form is right or not. I did not display the JDBC query in MapViewer. Does anyone know the second form is right? or Maybe give me a right form in a JSP request. (contour is a table , geom is the column of geometry attribute in contour)

in this request, other themes and JDBC network query theme work except the JDBC query theme. I guess the style or format in the following are not right.

Anyway, I hope you can give me instructions.

JDBC query against Sybase through jConnect5.5 in Oracle 9i Reports Builder

Hi There,
I am trying to connect to Sybase using JDBC query using jConnect55 driver.
I am not able to do so. I get an error:
ERR 62002: Failed to connect to the datasource JZ0D5 JZ0D5: Error loading protocol com.sybase.jdbc2//255.255.255.255//255.255.255.255
Driver entry in my jdbcpds.conf file is
<driver name ="jConnect55"
subProtocol ="sybase"
connectString ="mainProtocol:subProtocol://databaseName"
class = "com.sybase.jdbc2.jdbc.SybDriver"
connection = "oracle.reports.plugin.datasource.jdbcpds.JDBCConnectionHandling" loginTimeout = "0">
<property name="DatabaseName" value="tempdb"/>
</driver>
The entry I make in jdbc query connection dialog box is as under:
User Name:test
password:secret
Databse: 255.255.255.255:9999/tempdb
Driver Type: jConnect55
Can you point me where I am wrong?
Thanks in advance
Ketan Patel

Hi Sachin,
I too, got through the issue. Sorry am bit late in updating you. But still I would say it is not on consistent(my feedback as per I grabbed from the behavior. Say, I accepted the query in a particular order of WHERE clause, then If I change the order it will throw an error message saying "Incorrect syntax".)
Anyway working fine. Thanks for your immediate response with useful hints.
Rgds
Anand
Hi Anand,
Yes, JDBCPDS accepts all Select queries which follows SQL Specification.
It would be a valid query as per the database used.
Please try again, Bind parameters can be placed in any or all of the conditions of SQL Query in JDBCPDS.
I am able to use them in both the cases you told.
With Regards

JDBC Query using PL/SQL

I have gotten this to work in my Reports class but can not get this to work at my company. Basically I'm trying to use the JDBC query in Report Builder.
Here is my Ref Cursor Code:
CREATE OR REPLACE PACKAGE SCOTT.types is
type sqlcur is REF cursor;
end;
Here is my Pl/SQL function:
CREATE OR REPLACE FUNCTION SCOTT.test return Scott.types.sqlcur is
c1 Scott.types.sqlcur;
begin
open c1 for select * from scott.emp;
return c1;
end;
I can get this to work in SQL Plus by doing the following:
var r refcursor
exec :r := test;
print r When I go into Reports Builder->JDBC query I connect to the SCOTT db using tiger as the password. I type in the function name TEST and get the error "wrong number or types of arguments in call TEST". I have tried "call TEST" but that doesnt work either. If I use "call TEST" I get an error saying it expected characters ":=(@" etc....
I know my connection works because I can do a "select * from emp" and get results. Can anyone get this to work?
I'm running Report Builder 9.0.2.0.3
I have done multiple searches on this issue and most responses point someone to links that dont work or documentation. I have read them and my code above should work but doesnt........Please put some real examples or code that works with the "Scott" schema.
Thanks

hi Shawn
When running jdbc quesry based on SP with Oracle DB, the first parameter of the store procedure should be of ref cursor type and it shall be a OUT parameter.
For example:
CREATE OR REPLACE PACKAGE jdbcpdspkg AS
TYPE Empcur IS ref cursor ;
procedure proc_with_param (p_emp_cv out jdbcpdspkg .empcur, p1 in number, p2 in number , p3 in number, p4 in number , p5 in number) ;
Thanks

Multiple library.xml files normal?

I just made 2 iTunes libraries, both located in the Music folder on my internal HD. One is just called "iTunes" which gets backed up with time machine, and the other is called "iTunes For Backup", which I use for temporary music projects etc that I exclude from backup to save space.
The one called "iTunes For Backup" has an "iTunes Library.xml" file as normal, but the "iTunes" folder has both an "iTunes Library.xml" file AND an "iTunes Music Library.xml" file.
After playing around, I discovered that if I start from scratch and create a new library called "iTunes", initially it will create just the "iTunes Library.xml" file, but as soon as I've added songs and quit, it creates a second file called "iTunes Music Library.xml". If I create a new iTunes library and name it anything other than "iTunes", only an "iTunes Library.xml" is ever created, which I think is normal behaviour.
To be honest I don't even know if this is a problem, but I've never seen multiple Library.xml files inside the same iTunes folder before. And why it would have anything to do with what you name the library seems baffling. It strikes me as very odd behaviour so I thought I would throw it out there out of curiousity to see if this is normal. I'd hate to find out it's a problem after I've built a huge library.

I'm wondering the exact same thing.
I'm able to find a lot of resources on the itunes library.xml file, but hardly anything on the itunes music library.xml file…
I'm also lost as to how I import my playlists back into iTunes. I keep my music on an internal 'Media' partition and am pretty well versed with OSX, but can't seem to figure it out… All the problems relate back to both of these XML files. Importing one will import some of the playlists, but not all… Weird

How to send SQL query results to XML ?

Hey Guys, I am querying a DB with huge amount of traffic. A user select a particular lot and then details of the lot will be displayed in the following page. My concern here is that it takes really LONG to retrieve back the results coz it has to requiry in the following JSP page.
I was told to use XML to retrieve the dataset and store it. Hence, in the following query it will re-query only from the recordsets in the XML file (...Logically, should be faster rite ? ). Hence, how do parse my recordsets retrieved from the SQL query to an XML file ?
Any sort of suggestion , help, reference would be deeply appreciated ..Thanks !

Query LDAP to XML

I am having trouble using the Query Multiple LDAP to XML component. I have it configured right(?) in the workflow. I am trying to retrieve a couple of attributes about the user who is logged in. For now, I have a text box with an invoke button on my form to simulate the action of getting the logged in user.
In my process, if I hardcode a user in or if I invoke the process via the Components label it runs fine and returns the correct XML. If I try to invoke the web service via my form, I receive an "error attempting to read from file".
I have never queried the LDAP before and I am a little confused. Could anyone offer some help?

I have actually disabled the security for that service. I am thinking the problem is that the LDAP server has some sort of block on web service calls. Could that be the issue? All of my other web services (configured the same exact way) function just fine, and running the query in LiveCycle Workbench works fine. That leads me to believe that something is stopping the WSDL connection.

Processing the multiple sender xml one by one in a time gap to RFC

Dear Experts,
I have to process the multiple sender xml file one by one from FTP to RFC in time gap.
For Ex:
I will place 10 xml file in a FTP path at a time, PI is picking 10 file at a time and process it to RFC at a time.
Any other way to process the multiple file one by one through PI in a time gap to RFC
(i,e) PI needs to process the 10 files one by one, once the first file processed successfully from FTP to RFC then the next file to process in a time gap to avoid getting the error in RFC.
Kindly suggest your ideas or share some links how to process this multiple files.
Best Regards,
Monikandan.

Hi Monikandan,
You can use CE BPM with PI 7.1 But first check the suggestion of Anupam in the below thread:
reading file sequentially from FTP using SAP PI file adapter
