Sample Code - dmardemo.java

Could you help me understand this sentence in SQL?
"CREATE VIEW " + outputDataURI + " AS " +
"SELECT D." + caseId + ", " +
"CAST(MULTISET( " +
" SELECT DM_Nested_Numerical(SUBSTR(C." + originalColumn + ", 1, 30), has_it) " +
" FROM " + inputDataURI + " C " +
" WHERE C." + caseId + " = D." + caseId +
" ) AS DM_Nested_Numericals) " + newNestedColumn + " " +
"FROM " + inputDataURI + " D";
where:
outputDataURI = SALES_TRANS_CUST_AR_V
caseID = CUST_ID
originalColumn = PROD_NAME
inputDataURI = SALES_TRANS_CUST_V
newNestedColumn = CUSTPRODS
Best Regards,
Luis

When I execute this SQL sentence, it creates the view 'normally'. However, when I try to see the data, nothing appears in the column CUSTPRODS. Is there anyone who had this problem before?
Thanks
Luis

This is very likely a CLASSPATH issue. Make sure weblogicaux.jar is
at the head of your CLASSPATH.

Tips on how to write efficient java code for java mapping

hi
I do not have much knowledge in Java
Can anybody tell me some tips on how to write efficient and optimised java code to be used in java mapping
Thanks,

hi D'za,
JAVA in xi
A very important place where you will use JAVA in XI is while doing your Mapping. There will be cases when JAVA MAPPING is the best solution to go for. There are 2 types of Parsers available for JAVA Mapping. DOM Parser and SAX parser. Just got through the following links to understand more on Java Mapping and the APIs available.http://java.sun.com/j2se/1.4.2/docs/api/javax/xml/parsers/package-summary.html http://java.sun.com/j2se/1.4.2/docs/api/org/w3c/dom/Document.html http://java.sun.com/j2se/1.4.2/docs/api/org/w3c/dom/package-frame.html /people/prasad.ulagappan2/blog/2005/06/29/java-mapping-part-i

Need Sample Code for Vendor creation using JAVA API

Hi,
I have a scenario like Vendor creation using Java API.
1.I have Vendors (Main) Table.
2.I have look up tables like Account Group.
3.Also Qualifier table(Phone numbers) too.
Could you please give me the sample code which helps me to create Vendor records using Java API?
I need Code samples which should cover all of the above scenario.
Marks will be given for the relevent answers.
Best Regards

CreateRecordCommand create_command = new CreateRecordCommand(connections);
create_command.setSession(sessionId);
create_command.setRecord(qualified_record);
try
create_command.execute();
catch(Exception e)
System.out.println(e.toString());
RecordId record_id = create_command.getRecord().getId();
//Adding the new record to Qualifed Lookup value and setting the Yes Qualifiers
QualifiedLookupValue lookup_value = new QualifiedLookupValue();
int link = lookup_value.createQualifiedLink(new QualifiedLinkValue(record_id));
//Adding Yes Qualifiers
lookup_value.setQualifierFieldValue(0 , new FieldId(<FieldID of Yes Qualifier>) , new StringValue(<StringValue>));
//Now adding LookUP values
//Fetch the RecordID of the value selected by user using the following function

Java Mapping sample code

HI all,
I want to learn how java mapping can be done in XI.
I have created a javaMapping class implements StreamTransformation .
I am not getting what code should be written in execute method. I have included all the jar files required.
Please can anyone give me a sample code that should be written in execute method for a simple Message mapping.
I presume we use jaxp Api for that,but I am not getting the exact way to proceed further.
Thanks
Yomesh

Thanks Anad And Shridhar,
I am able to do java mapping now.Actually I was not understanding how the input schema will be read and converted into output schema. Now I got that the DefaultHandler class's methods like startDocument EndDocument ,startElement and EndElement takes care of this. We have to just implement these methods and they are called automatically when corresponding tags are read.
Thank You verymuch for your help,
Yomesh

Can u please send me a sample code to upload and download a file using java

Hi, Thank u.
Sorry, I forgot to attach a code. Here it is.
Actually i need to upload a file to a remote server and download it from a server to my machine. I'm trying it using servlets and using tomcat5.0 as a servlet container. Here i'm sening a code used to upload a file. Let me know whether it works. Only few lines are here.
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.lang.Object;
import java.util.*;
import java.lang.String;
import com.oreilly.servlet.MultipartRequest;
public class FileUpload extends HttpServlet{
     public void doPost(HttpServletRequest req, HttpServletResponse res)throws
     ServletException, IOException{
     MultipartRequest multi=new MultipartRequest(req);
     String file="file1";
     byte[] b=file.getBytes();
     InputStream in=null;
     BufferedInputStream bis=null;
     FileWriter fw=null;
try{
     in=multi.getInputStream("file1");
bis=new BufferedInputStream(in);
     File output=new File("/fileuploadtest");
     fw=new FileWriter(output);
          int i;
          i=bis.read();
          while (i != -1) {
fw.write(i);
i = bis.read();
     catch(IOException e){
          System.out.println("Exception=" +e);
finally{
     try{
          if(in!=null)
          in.close();
          if(bis!=null)
          bis.close();
          if(fw!=null)
          fw.close();
     catch(Exception e){
          System.out.println(e);
This code is giving error as: cannot resolve symbol: class MultipartRequest
Why is this happening?
Pls let me know whether this code works or no and also i have written form.html.
Can u pls tel me whether there are ways in which i can write a code to upload a file using servlets without using third party packages. Pls help.
Also how should be the servlet mapping for this code.?

Need sample code in webdynpro for java

Hi all
actually i have one webdynpro form which is having multiple input elements. for example name,address,phoneno,price quantity and amount. and there is update button for that form.
when i click the update button the multiplication of quantity and price value will be updated by in one input field which is part of the another webdynpro form is part of the same view.
i want to update the input field in another form only when i change the value of either price or quantity otherwise the value of inputfield in another form should be same.
now how do we retrieve the event of either price or quantity inputfield which only changes rather than changes of name or adreess.
only when i modify the value of price or quantity in form and updated button then only the multiplication will be reflected in inputfield of another form.i dont want to reflect that inputfield of another form when i changes of other inputfields except price or quantity.
please provide the sample code on the same...especially how to retrieve the event of that price or quantity in a form..
Regards
Suresh babu

Hi Suresh,
please post your issue to the Web Dynpro forum.

Java + Open SQL sample code..

Hi All,
I want to use Open SQL in our project, Can any one send me a Stand alone sample example of Java and Open SQL.
also point me, from where i can get informations regardig the same..
We have SAP J2EE 6.20.
Also pls let me know the supporting jar,zip files, and from where can i download the same.
I googled, but i couldnt get any sample examples..
1. Does SAP J2EE 6.20 support Java & Open SQL.
2. What all supporting jar files, do i need and from where can i get the same..
Regards,
Shridhar..

Hi Sridhar,
           To use open sql in particular project in Netweaver Studio,you should have WAS 6.40.SO the current version which you had mentioned WAS 6.20 doesn't support open sql.
           Secondly to use open sql you should place the driver .jar file in the lib folder of your respective perspective.you can download the same .jar file from the vendor's website(eg:- oracle).Then you need to conect to the DB,have youe executable statement and iterate thro' your resultset similarly what you in an ordinary JDBC program.
            Hope this helps.

Error creating GUI for dmardemo.java

Hi friends!
I took the demo dmardemo.java (Association Rules) which comes with the ODM for Java to test Data Mining function in the sample database Sales History. In the original code, the application ran normally. However, I'm trying to create a GUI to execute the most important funcionalities like creating view, preparing and building model and restoring rules and itemsets. I created a visual class in the same project where the demo is. I've done some changes in the methods, like putting some input parameters for them. e.g.:
[i]public static void buildModel(String viewModelo, String configTask, String modelName, String taskName) throws JDMException
Connecting is ok. However I can not create the view.. When I execute this method for creating the view, some erros occurs, like:
Create build data view...

I have to tell you that the problem was occurring because of the clean() method. It must clean all views created before, and I was ignoring its execution. Now, another thing is happening: every time I made a call for it, an exception occurs, telling me that I must pass an input parameter for this method, and a null value for the objectName is not allowed.
However, this method doesn't work with any parameters.
What could be happening?
Thanks a lot!

Association Rules - dmardemo.java - DisplayAssociationRules method

Hi, friends!
I'm making some changes in the sample Java demo for the Association Rules - dmardemo.java. I've created another method which contains the name of the model just created before and in this same method, I call the method to display the association rules detected:
public static void restoreRules(String modelNome) throws JDMException {
m_modelName = modelNome;
model = (AssociationModel)m_dmeConn.retrieveObject(
m_modelName, NamedObject.model);
displayAssociationRules(model);
In another class, which is a GUI, I'm trying to call that method to restore all the rules found in the mining process and display them in a jTable Swing component. For this, I've tried to adapt the main method (displayAssocationRules) to do this, as follows:
public static Object displayAssociationRules(AssociationModel model)
throws JDMException {
// DISPLAY TOP-10 ASSOCIATION RULES
Object[] obj = new Object[5];
int contador = 0;
// 1. Set order by confidence DESC, support DESC
OraRulesFilter filter = (OraRulesFilter) m_filterFactory.create();
filter.setOrderingCondition(
new RuleProperty[] { RuleProperty.confidence, RuleProperty.support},
new SortOrder[] { SortOrder.descending, SortOrder.descending }
// 2. Set to return the first 10 rules only
filter.setMaxNumberOfRules(10);
// 3. Retrieve rules
Collection rules = model.getRules(filter);
Iterator iRules = rules.iterator();
while( iRules.hasNext() )
OraAssociationRule rule = (OraAssociationRule) iRules.next();
obj[0] = rule.getRuleIdentifier();
//System.out.print( "Rule " + rule.getRuleIdentifier() + ": " );
Itemset antecedent = rule.getAntecedent();
//obj[1] = antecedent.getItems();
Object[] ante_items = antecedent.getItems();
// sort the items in antecedent to produce deterministic order of items
TreeSet sortedSet = new TreeSet();
for(int i = 0; i < obj.length; i++)
sortedSet.add(ante_items);
obj[1] = ante_items;
Iterator sortedI = sortedSet.iterator();
/*while(sortedI.hasNext())
System.out.print(sortedI.next() + " ");*/
Itemset consequent = rule.getConsequent();
Object[] cons_items = consequent.getItems();
obj[2] = cons_items;
obj[3] = m_df.format(rule.getSupport());
obj[4] = m_df.format(rule.getConfidence());
/*System.out.println("==> " + cons_items[0] + " (support=" +
m_df.format(rule.getSupport()) + ", confidence=" + m_df.format(rule.getConfidence()) + ")" );*/
return obj;
Some parts of the old code are present in that for you to compare what I've done. However, it's not working. What should I do to see the rules generated in the process in a jTable?
Regards
Luis

As you can see in the code above, I've split the code into two parts. However, a problem is happening when I try to restore the rules to the GUI.
"Exception in thread "AWT-EventQueue-0" javax.datamining.JDMIllegalArgumentException: The required argument objectName is null. Supply a non-null value."
It says that I'm not passing any parameters to the method. But, as you can see, in the first method I've created, I took the name of the model and transfers it for the method displayAssociationRules as a AssociationModel objet.
In the GUI, in an event for the button "Restore Rules", I've put this code below:
String modelo = Principal.getModelName(); // where Principal is the main GUI class for the execution of the process.
dmardemo.restoreRules(modelo);// I call the method in the dmardemo class to restore the rules having a String (modelo) as its parameter. That's when the problem happens. Is the argument really null, as the error message says?
Regards
Luis
