• PartialTriggers application using java code?

  We can perform a partial Trigger on a component using java code?
  
  For example,.
  I have a textBox element and an attribute of partialTriggers link commandButton.If in the text box for the commandButton control, he gets the renderer every time I click the commandButton control.
  
  Can I get the same thing by writing some piece of java code inside the listener of the CommandButton action?
  
  Kind regards
  Lokesh.

  If you bind the element to an attribute of bean (i.e. attrXYZ), you can use

  RequestContext.getCurrentInstance().addPartialTarget(attrXYZ);
  

  in the listener to update it.

• How to create a BPEL Process task using java code

  Hello
  
  I created a BPEL process (for creating task), in which my requirement is that I need to create a task based on some inputs and assign it to the user in partucular and then get out of this flow.
  
  earlier, I felt that I will use the human task activity. but when I use that task will be created in the same process and proceedings will be stuck on there until human intervention (the BPEL process waits for the result.).
  
  is it possible that I can use Java activity and create tasks from java code, 'I know how to assign a specific user task. Please tell me.

  Hi Abhishek
  1. you can try this alternative approach and it should work.

  2. basically, most of the BPEL process eventually auto generated Web services (.) WSDL). When we create a BPEL process, everything we do is give diagram of input, output schema and creates a bpel process with the default operation named as "process" in all the old versions as up to 11.2 SOA (and maybe before). BUT SOA 11.3 from, we can create a process BPEL, with our own WSDL and our own scheme. There is no restrictions like having only a single operation named 'process', etc.. In any case, what I mean is, each BPEL process ends up as a WebService, with entry and exit of the payloads of XSD.

  3. from the JDeveloper itself, locate the .wsdl for your BPEL process under the Workflow project. Create a new project of Proxy customer service Web and generate a customer for this wsdl Web service proxy. This will create you Service, Port and JAVA classes equivalent payload theoretically in your case taskpayload.xsd with these 4 items you have. Ignore the full blown the HumanTask which has all the system elements and attributes of a task of bpel. All you need is to undertake a task with your own payload data. Create a simple Client Java (EJB or Servlet later to make more flexible). In this Java client, retrieve the Service object in the proxy and port. Then instantiate the java class that represents the payload. Set 4 values you want and set the user name, etc. You may need some adjustments for the setting of the user. Then the port invoke otherwise (go your java object here).

  Sample code snippet
  prepare the message for BPEL of appeal; Define the fields that can not be null
  MyPayloadRequest myPayloadRequest = new MyPayloadRequest();
  myPayloadRequest.setInitiator("");
  myPayloadRequest.setTitle("");
  myPayloadRequest.setEmployeeName("");
  myPayloadRequest.setEmpContact("");

  web service client Get for BPEL receive point and call: first generate client proxy
  MyBPELPProcess_client_ep serviceClient = new MyBPELPProcess_client_ep();
  MyBPELPProces proxy = serviceClient.getNewMyBPELPProces_port ();
  proxy. Process (myPayloadRequest);

  Please note that you can also use the SOA workflow API and the Manager back call personalized for this first task classes. In this class, you can have the methods of the interceptor, which is called each time a task is initiated, saved, Submit, approve etc etc (all events essentially). This gives you access to all the objects in a workflow with full charge blown. So you can always get the data you pass above and in this custom class, the value of the user, date/time etc..

  It's just a different approach you can try.

• Inserting data in several related tables using the database

  Hello world
  I'm working on a BPM application using Oracle BPM 11.1.1.5.0 and JDeveloper 11.1.1.5.0.
  
  In my database, I have two tables, loan and guarantee that are related by a field named employeeID (PK on loan) and FK in warranty.
  Each line can have several lines of guarantee.
  
  At this point, I'm doing an entry form for the user to insert data in the two tables.
  
  I did successfully before with a single table that has no relations.
  
  The way I'm doing here is, after the creation of the database successfully adapter, a type of LoanCollection is created in the types module, which can be used to create business objects and data objects of.
  
  The problem is when I create an object of type loanCollection process data and then create a UI generated automatically on that basis, only the fields in the primary table (the Table of loan) appear in the form.
  On the other hand, if I create a business object based on the LoanSchema, the form for all of the two tables is created automatically (the loan as a form, the guarantee in a table), but then, when I try to access it in the section processing service mission which calls the database adapter, I have no access to such.
  In fact, the only type which can be used in the service task is the process based on the loanCollection data object.
  
  To summorize, I have to use the type of business for my UI object to include all the fields in both tables, so I have to use the data object from the collection process in the transformation of service task dialog box.
  And I can't find a way to map to another.
  
  Can someone help me with this please?
  Thank you very much

  Try to follow these steps.

  1. create a new module in your catalogue our BPM project management section
  2. in this new module create 3 Business Objects - (LoanBusinessObject, GuaranteeBusinessObject and GuaranteeArrayBusinessObject)
  3. Add the attributes appropriate to the LoanBusinessObject and the GuaranteeBusinessObject so that they mimic your database tables, then to the GuaranteeArrayBusinessObject add an array of type attribute GuraranteeBusinessObject
  4. now you need to create two process data objects, type loanProcessObject LoanBusinessObject and type guaranteesProcessObject GuaranteeArrayBusinessObject
  5. as inputs to your human task adds the loanProcessObject and guaranteesProcessObject, these should now be available in your data controls and can be used to auto generate the form
  6. in your dbadapter you'll then use XSL Transformation and use for each so that it will write the data to the ready table and all the line items of warranty for the warranty table.

• Force sync LDAP via the Java Code

  Hello
  
  I have 2 servers LDAP (AD) and there are a few changes made every night, using Java code. I want force synchronization between these 2 servers after that change is done using Java. I am not able to find any mothod to do by using the LDAPContext class.
  
  Any help on this is appreciated.
  
  -Spengler.

  LDAP replication aka sync is standard and implemented differently on the application of each seller, so there is no standard interface that can use Java. You would be better of the configuration of the synchronization directly on the side of things AD. You could use Java potentically to launch/run a native ADSI script that forces synchronization on if configured AD.

• Loading XML into the relational Table data

  Hello

  I get a generated XML file to other tools (Windows), I am trying to create a Linux shell script that will gather the necessary XML file to my Linux server, then ask Oracle to use this file to load the XML data into a relational table. This activity and the data will be needed on an ongoing basis.

  I tried two ways. First, I loaded the XML document into the database and tried to extract the data directly from the document, but it does not work. Now I want to try to read the data directly from the file on the server through select, however I don't get all the returned data. In the Select statement below, I am trying to query the data to see what is returned for my tests.

  Create Table ci_results_table (transactionID Varchar2 (100), //transactionID should be PrimaryKey but became errors in test of insert, PK so deleted NULL value)

  message Varchar2 (200),

  This Varchar2 (50).

  XMLType of the ProcessedDate,

  status Varchar2 (50).

  sourceFile VarChar2 (100));

  Select x.*

  from XMLTable)

  ' TSPLoadResults/results '.

  PASSAGE xmltype (bfilename('CMDB_DEVADHOCRESULTS_DIR','LoadResults-HP_146.results.xml'), nls_charset_id ('AL32UTF8'))

  COLUMNS

  transactionID PATH Varchar2 (100) 'TransactionID '.

  Result XMLType PATH 'result ',.

  Message Varchar2 (200) PATH "Message."

  PrimaryKey Varchar2 (50) PATH "PrimaryKey"

  Date of ProcessedDate path "ProcessedDate."

  Status Varchar2 (50) PATH "Status."

  SourceFile VarChar2 (100) PATH "SourceFileName.

  ) x

  ;

  Eventually, I'll have to build on that to limit the returned data to records where SourceFileName is like '% PA' and insert what is returned in to the ci_results_table. Attached is an example of the XML results file I am trying to load, it is named "ResultsTransformedtoUnix" because I used dos2Unix to convert Unix which can be good or bad. (I send the output file must be converted to the format BACK until the other application can read). Original (before converting Unix) file named in the script is also attached.

  Help, please. Thank you!

  Hello

  I see some bad things in your query.

  (1) obvious one, explaining why you get all the data: there is a typing error in the XQuery expression, there 'result' not'slead.

  (2) ProcessedDate can be extracted as a date (at least not directly) because it actually represents a timestamp, use the TIMESTAMP WITH time ZONE HOURS and cast back to DATE data type in the SELECT clause

  (3) transactionID is an attribute, it must be accessible with ' @' (or ' attribute:' axis)

  (4) if the encoding of file really is ISO-8859-1 as suggested in the prologue, then do not use AL32UTF8 but the name of the corresponding character set: WE8ISO8859P1

  Here is the query to work:

  select x.transactionID
       , x.Message
       , x.Primarykey
       , cast(x.ProcessedDate as date) ProcessDate
       , x.Status
       , x.SourceFile
  from XMLTable(
         '/TSPLoadResults/Result'
         PASSING xmltype(bfilename('XML_DIR','LoadResults-HP_146.results.xml'), nls_charset_id('WE8ISO8859P1'))
         COLUMNS
           transactionID Varchar2(100)            PATH '@transactionID',
           Message       Varchar2(200)            PATH 'Message',
           PrimaryKey    Varchar2(50)             PATH 'PrimaryKey',
           ProcessedDate timestamp with time zone PATH 'ProcessedDate',
           Status        Varchar2(50)             PATH 'Status',
           SourceFile    VarChar2(100)            PATH 'SourceFileName'
       ) x
  ;
  

  Directly on the file using this query will only be decently (for large files) on 11.2.0.4 and beyond.

  On older versions, first load the file into a (temporary) XMLType column with binary XML storage and CHOOSE from there.

  because I used dos2Unix to convert Unix which can be good or bad.

  This conversion should not be necessary.

• XML document to tables relational object

  Experts: I followed several examples online and was able to insert an XML document in a relational Table of Oracle objects. I see that Oracle creates a table behind the scenes and some types of data which map to the elements in the xsd file.
  
  My hypothesis is that I can run selects plain

  ( select col1, col2, col3 from OR_XML_Table )

  against the inserted xml document columns lbut infact I still have to xpath in the relational table object for oracle to access the values of the element.
  
  Is it possible to insert xml elements to Oracle relational tables that can be queried without xpath expressions.

  The error is pretty self-explanatory.
  The columns of three of the projects of query, but you try to generate a view of the object (with a column of the single object).

  You also use the deprecated functions.

• Approach to analyze the large number of XML files in the relational table.

  We are studying the possibility of XML DB to treat a large number of files from same day.
  The goal is to parse the XML file and store it in several relational tables. Once in the relational table don't care us about the XML file.
  The file cannot be stored on the file server and must be stored in a table before analysing because of security concerns. A third-party system will send the file and it will store in the XML database.
  The file size can be between 1 MB to 50MB and high performance is very that much is expected of other wise men, that the solution will be discarded.
  Although we have no of XSD, the XML file is well structured. We are 11g Release 2.
  
  Based on the reading, that's what my approach.
  1. CREATE THE DONNEES_XML TABLE
  (xml_col XMLTYPE)
  XMLTYPE xml_col STORE AS BINARY XML NAVIGATION;
  
  2. third will store the data in the donnees_xml table.
  3. create XMLINDEX on the unique XML element
  4 create XMLTYPE views
  CREATE OR REPLACE FORCE VIEW (V_XML_DATA)
  SType,
  Mtype,
  MNAME,
  ROT
  )
  AS
  SELECT x."Stype"
  x."Mtype."
  x."Mname"
  x."ROT".

  PASSAGE t.data
  COLUMNS Stype VARCHAR2 (30) PATH "Stype"
  Mtype VARCHAR2 (3) path "Mtype."
  MNAME VARCHAR2 (30) PATH "MNAME"
  ROT VARCHAR2 (30) PATH "OID") x;
  
  5. loading mass analysis of data in the staging table based on the column in the index.
  
  Please comment on the process that precedes any suggestions that can improve the performance.

• What is the best way to apply choice relational tables in the XML document?

  I've got an XML document from outside I turn with full DB XSLT document.
  
  Some parts of the document contain codes I want to tranfsorm to significant labels of relational tables in our database.
  
  On road is to disassemble the XML into the relational views and join these views with tables of choice and then back, this time with labels translated, using XMLElement, etc...
  
  Is there another way less heavy? For example,.
  
  Select updateXML)
  xml_dta
  ,'/ / section_to_translate/node_to_translate/variable / text () '
  ,(
  Select the label
  of table_recherche
  where Group = extractValue (current_node, '... / Group/Text () ')
  and code = extractValue (current_node, '... / variable/Text () ')
  )
  ) xml_dta
  from my_table
  where... criteria
  
  However, I do not know how to move from the current node to the extractValue function (if it is possible?.)
  
  Anyone done the second way?
  
  Thank you

  You didn't tell the version of your database, so I assume one of them later.

  You can include the part of the translation in the XSL transformation, by accessing an external research paper generated from the database beforehand.

  (4) the sheet XSLT stylesheet (stored in XDB repository as well): emp.xsl

  The transformation is rather bland, but the interesting part lies in access to external document within it.
  I used a key to index the JOB_ID/function pairs.

  (5) last step, apply the transformation:

  SQL> select xmlserialize(document
    2   xmltransform(
    3    xmltype(bfilename('DUMP_DIR','emp.xml'),nls_charset_id('AL32UTF8')),
    4    xdburitype('/public/temp/emp.xsl').getXML()
    5   ) as clob indent
    6  )
    7  from dual;
