Disclaimer:Information contained in the following is presented as is. This tutorial assumes you have basic programming and software configuration knowledge. All tutorials are based on IBM Notes Domino orOracle Fusion Middleware, including and not limited to items stated in the System Requirements. Should you need to familiarize yourself with IBM Domino Designer or Oracle JDeveloper environments, prior to continuing, stop now and see our Journal Entries page on our website: www.dokollsolutionsinc.com for additional support...

Foreword:

Samples included in this Journal Entries document are part of a series, be sure to consult other versions of the documentation to benefit in full.

Introduction:Go through IBM Domino Designer to find Java and JavaAgent code in Xpages App samples that can be used to create an XML file and post it to Domino Browser. The code will need to gather values from existing back-end View(s) containing user records to be accessed by external Oracle JDeveloper ADF application. In turn, the data will be inserted into an awaiting IBM DB2 database table using a JSF button. All areas of interest, obviously, will be highlighted for your convenience.

++++++++++++++++++++++++++++++++++++++++++++++++++++>>2015.10.31.9.56.AM

Let us begin by tracking down all necessary Xpages code bits we have already in IBM Domino Designer for XML, TXT, CSV data to add to Oracle JDeveloper ADF/JSF button and pull in a URL, extract the values to be submitted to IBM DB2...

Searching for available code in existing Xpages App...

http://www.dokollsolutionsinc.com/

By the way, for those of you who are probably not familiar with the ADF terminology, here is a current definition and what it does: Oracle ADF, otherwise known as Oracle Application Development Framework, provides a Java framework for building enterprise applications in Oracle JDeveloper. It provides visual and declarative approaches to Java EE development.

Most of you are well-aware of what JSF stands for 'Java Server Faces', and if you searched information about Xpages, you would find that this Framework is widely used within the IBM Domino Designer environment, it sits on top of JSF and works very well with Java.

That said, let's dive into a current Xpages sample and other standalone programs to find a way to get data into an XML or CSV file, load that in a URL, grab it using an ADF/JSF application in JDeveloper to insert into IBM DB2.

Here is the full code in screenshot above to do what we need, we will have to split the XML or CSV file (most likely going to be an XML file) obtained from IBM Notes Domino application and submit to DB2ADMIN.NOTES_DOCS_RPT, our IBM DB2 database table.

Hint: You should change the name of the Array 'values' variable we have up there, since VALUES is a reserved term in databases; do that for sure if you copy below code sample, try to limit time spent on troubleshooting...

/** * Created: 2012.04.21.5.56.PM * Build Results into DB2/NSF with CSV */package com.dokoll.solutions.inc.cvs.trials;/**

//...//Start of Programpublic class ReadCSVFileIntoDB2Bean{ //...

try { Connection connection = DB2Connector.getConnection();

//create a Statement object to execute the query with //2012.04.21.6.02.PM //TO DO: Attempt using Prepared Statement here... Statement statement = connection.createStatement();

// Select* from UserNewLineOutboundInformation.csv BufferedReader br = new BufferedReader(new FileReader("C:\\temp\\CSV_DATA\\BULK_CSV_COM_DATA_SPLIT_2012.csv")); String line; while ( (line=br.readLine()) != null) {

String[] values = line.split(",");

//Convert String to right type. Integer, double, date etc. statement.executeUpdate("INSERT INTO DB2ADMIN.NOTES_DOCS_RPT VALUES('"+values[0]+"','"+values[1]+"','"+values[2]+"','"+values[3]+"','"+values[4]+"','"+values[5]+"','"+values[6]+"','"+values[7]+"','"+values[8]+"','"+values[9]+"','"+values[10]+"')"); //Use a PeparedStatemant, it´s easier and safer System.out.println("Insert these in to DB2: " + values); } br.close(); // clean up statement.close(); connection.close(); } catch(Exception e) { e.printStackTrace();

} }

Below are other code samples being considered to salvage for parts... this one would be perfect for reading from CSV, and creating data for an XML file.

//Button code public static void doGetCSVForLogNSFData() {

//... //Entering try catch

try { // load the driver into memory Class.forName("org.relique.jdbc.csv.CsvDriver");

// create a connection. The first command line parameter is assumed to // be the directory in which the .csv files are held Connection conn = DriverManager.getConnection("jdbc:relique:csv:C:\\temp\\CSV_DATA\\");

// create a Statement object to execute the query with //2012.04.21.6.02.PM //TO DO: Attempt using Prepared Statement here... Statement stmt = conn.createStatement();

//String [] SearchTerms = {""}; // Select * from BULK_CSV_COM_DATA_SPLIT.csv ResultSet results = stmt.executeQuery("SELECT * FROM BULK_CSV_COM_DATA_SPLIT"); int docount = 0; // dump out the results while (results.next()) { //TO DO: Write a separate JavaBean to build setters //that can used in Xpages to show entries newly made... String strFileDate = results.getString("FileDate"); String strFileTime = results.getString("FileTime"); String strErrorAmPm = results.getString("ErrorAmPm"); String strErrorRequest = results.getString("ErrorRequest"); String strErrorOrigin = results.getString("ErrorOrigin"); String strErrorDescrip = results.getString("ErrorDescrip"); String strErrorLang = results.getString("ErrorLang"); //connect to NSF back-end to load data in

Database database= (Database) FacesContext.getCurrentInstance().getApplication().getVariableResolver().resolveVariable(FacesContext.getCurrentInstance(), "database");System.out.println("Connected to Database..." + database);

//declare and initialize doc variable//begin creating your documentDocument submitDocument = (Document) database.createDocument();//load to form in your back-endsubmitDocument.replaceItemValue("Form", "LogReport");submitDocument.replaceItemValue("FileDate", strFileDate);submitDocument.replaceItemValue("FileTime", strFileTime);submitDocument.replaceItemValue("ErrorAmPm", strErrorAmPm);

submitDocument.replaceItemValue("ErrorRequest", strErrorRequest);submitDocument.replaceItemValue("ErrorOrigin", strErrorOrigin);submitDocument.replaceItemValue("ErrorDescrip", strErrorDescrip);submitDocument.replaceItemValue("ErrorLang", strErrorLang);

//Load to Console for debugging purposes//to console with this exercise (save your space as much as possible)

System.out.println("strFileDate " + " strErrorDescrip"); System.out.println(strFileDate + " " + strErrorDescrip); //save this doc, otherwise it is not recorded submitDocument.save(); //increment counter

docount += 1; } // clean up results.close(); stmt.close(); conn.close(); } catch(Exception e) { e.printStackTrace(); } }//end of program... }

in this case, rather than going to IBM Notes Domino database via Xpages form, as seen above, data will be submitted to DB2 via JSF page in JDeveloper... Let's have a look at additional code samples. We want to show the full code that creates the XML. Below is just the sample that reads the URL...

to even get there, at a stage where we can actually read the file, we need a file... Below is the JavaAgent that will help us create our wonderful XML file

Previously submitted Information:The IBM Domino Designer JavaAgent above was posted earlier, at least an excerpt of it, as a screenshot. We modified the code behind the scenes to grab values from the right Domino View, containing the user data we need, and tested it in the browser. Now, we will run it under a JSF button in JDeveloper to launch data to Oracle WebLogic console. We've done this before in Domino Designer,so the process is full-proof. This is the same code we will combine with the CSV to DB2 bit you saw in this document, it will be used to submit into our DB2ADMIN.NOTES_DOCS_RPT table....

Modified the original XML grab sample from Domino Designer, now running it in JDeveloper to yank XML data and show to WebLogic console as first step-

JSF page ran successfully in the browser. Currently the data is read in JDeveloper's WebLogic server, let's split it into parts to be able to use the strings bound for DB2 columns.

Lastly, to make it interesting, we can get the values into JSF inputText controls or as a list from the DB2 back-end. This is actually a 'Nice to do' type of thing, but we think it would be an added feature to the ADF project. Our goal is to get the data to IBM DB2, once we have achieved that, we may decide to just go with the flow and put that last one in...

Brief Recap:

We found all pieces of code we can use to combine into a complete process to grab the XML file, which needed to be created using the sample JavaAgent found in our vault. We also had an ADF App in JDeveloper on standby, we popped in the finished/combined Java code under a button in the JSF design. You have just had the first look of the completed Java method at work, successful entries shown to WebLogic console. We will close this Journal Entries documentation here, 17 pages in all... We can start a new document and continue our research, on our way to IBM DB2 submissions.
