JAVA to retrieve MDM data

Hi,
Can any one point me the step by step to connect, retrieve data from SAP MDM with NetWeaver Developer studio..
I have installed NWDS and MDM 5.5 SP06 .. I tried by importing jar files in to NWDS preferences.. But I am unable to connect to MDM.. I copied the code and pasted in NWDS but all the methods, imports are in error status..
Thanks
Rajeev.

Hi Rajeev,
In addition to Ravi's answer for MDM - NWDS you need to install JDK 1.5 on your machine before NWDS 7.0/7.1
also you must have MDM_JAVA_API and MDM_JAVA_WD_FRAMEWORK components needs to be deployed on your track.track specifically NWDI I am stating.
some external lib files may or may not be required to be deployed on the track.
as far as the errors are concern make sure you are building your project(rules composer/wddynpro) DC in good build state- > then refresh data model- > then proper deploying on track.
you can follow the below link as well more information on NWDI
/docs/DOC-8227#section11 [original link is broken]
Hope it helps.

Problem: Unable to retrieve workflow data from MDM repository

This is a new MDM installations scenario for version 5.5 SP05 (5.5.40.83).
After installing MS Visio, finding problems connecting it with the MDM Data Manager. After doing MDM workflow installations, able to initiate the MS Visio Workflow from MDM Data Manager and can see the Pane-MS Visio Workflow Stencil but not the able to see the Pane-MS Visio Workflow Stencil Details that appears below the Pane-MS Visio Workflow Stencil. Secondly geting a pop-up with the error message as - 'Unable to retrieve workflow data from MDM repository.'
I have added a parameter Mail Server=MailServerIPAddess (the existing IP addr), but it hasn't helped.
Can any one please help me in this !

Hi
As Felix mentioned, it might be a version compatibility problem.
You have also mentioned that mail server is not working for that do this
Mailserver = SMTP server.company.com ( ex. Mail.company(xxxxx).com)
MDM workflow notify task is working after rebooting the Machine. So the rule is after making changes to MDS.ini file reboot the machine ,to observe the consequence of configurable changes.
If u need anything this let me know.

Can you elaborate the thing... I don't think /*+ APPEND */ this is working for me ,still I am getting same error.
If you have any other suggestion,I would like to hear.
Should i not put commit after some 500 records inserted ? As i am putting commit once after whole data gets inserted.

Deleting DataLocationGroups (with MDM Data Manager or MDM Java API)

I´ve a lot of DataLocationGroups which are results of tests (importing pictures into the images tables but not stored as BLOB). I can´t see that the underlying table is exposed within MDM Data Manager. So i tried to delete the useless nodes with the DeleteGroup command.
However this seems not to be supported by the API
com.sap.mdm.commands.CommandException: Deleting of data location groups is currently unsupported
at com.sap.mdm.group.commands.DeleteGroupCommand.execute(DeleteGroupCommand.java:91)
I´m using the new Java API with MDM 5.5SP6.
No chance to remove the nodes?

Thanks for your answer. I would possibly open a service call to check if there is a hotfix available. Maybe you have some idea how i can check if the a Location is already existent? From experiments when importing with the MDM Data manager, it seems that a path is represented by a tree of HierLocationGroupNodes.
For example: I´ve imported from
cde271480MMPPpictures.jpg using the Data Manager. When using the RetrieveGroupTree Command, i can see that there are two nodes named cde271480 (Id: GN39) with child node named MMPP (Id: GN89).
Maybe i now want to use the API to import a picture from
cde271480 estlocation into the images table. To get a locationID usable for the setDataLocationId i had to compare the pathname of the picture with elements of the GroupTree from the root. If one element of the path is not existent in the tree, i have to create this new element and connect it to the parent. And i can then use the ID of the Leaf node for the DataLocationId. Is this correct?

Acess MDM data through Web service

Hi All,
Business requirement is to retriev data from the MDM through web service.. How can we do it? Do we have any step by step documentation?
They want to retrive data based on service funtionality.. suppose say based on there system they want to see all the data imported on a particular date.. They want to go with java..
Thanks
Rajeev

Heyy
if you want to retrive the data based on service, as per my understanding you should go by webdynpro component
you can refer the below link.

How to retrieve input data from a HTML form in the UTF-8 cha

I encountered the following problem with a JWeb Application:
I tried to write a JWeb-Application for OAS 4.0, that retrieves
input data from a HTML form and writes it into an Oracle
database.
All processing should be done in the UTF-8 character set.
The problem is, that the form data retrieved by getURLParameter
are always encoded in a non-unicode character set and I found no
way to change this.
Can anybody tell me what I should do to get the form data in the
UTF-8 character set?
null

Hi
Try set in the JWEB application's Java environment such
SYSTEM_PROPERTY: file.encoding=UTF8.

PLEASE HELP!!! Problem with Java and SQLServer Text data type

Hi there,
I have a java app. that reads from an MS SQLServer database. Originally, all long text fields were declared as NVARCHAR(200). The program worked fine.
Someone then advised that I change all long text fields to the TEXT data type. The program now crashes out with the following Exception:
"java.sql.SQLException: [JRun][SQLServer JDBC Driver]This ResultSet can not re-read row data for column 25."
Basically, I have a method that retrieves a resulset and iterates through it. The resultset is passed to another method during each iteration. In the example below, the 'specialNote' field used to be NVARCHAR(200). The code worked fine. Then when it was changed to TEXT, the program no longer works with the above Exception thrown.
Anyone know any special way SQLServer TEXT data types need to be handled?
Thanks for any advice!
The code looks something like this in functionality:
<CODE>
public void method1 (Connection conn)
Resultset rs = conn.createStatement().executeQuery("SELECT * FROM ProductBB");
while (rs.next())
method2(rs);
public void method2 (ResultSet rs)
String str = rs.getString("specialNote");
</CODE>

Hi JWoods,
Thanks for the suggestion. I originally had the code do what you suggested, ie, get the resultset then retrieve the data all within the same method. The data is then used to set properties in an object.
When I had to create another method that also retrieved a resultset but using a different primary key, then also use the returned data to set the properties in the same type of object, I didn't want to repeat the setter code. That's why I decided to pass the resultsets to the same method that did the property setting.
Unfortunately, it stopped working with the data type change.
Any other thoughts?

Too much code. It's also not well intented nor formatted. I don't see a question either or it got lost in that heap of unformatted code.
I will only answer the question in the thread's subject:

To display, make use of JSTL's c:forEach.

How To Retrieve All Data From a Submitted h:dataTable ... ?

I have a table together with a button displayed in the browser. Upon click on the button, an action is invoked.
I would like to retrieve the data in the entire table in this action.
Because the displayed table is created by a managed bean class ListAction, "personnel" is the property of the bean class, and the "personnel" is a List, when I try to retrieve the data this way:
                                          ListAction listAction = new ListAction();
          DataModel personnelData = listAction.getPersonnel();
         List personnel = (List)personnelData.getWrappedData();The compiler says that a List cannot be converted to DataModel.
What should I do? I need guidance.

Thanks for the reply. I tried to follow your advice. Somehow, I ran into a runtime ClassCastException.
In my xxx.jsp I have
<h:dataTable value="#{arrival.personnel}" var="pInfo">
<h:commandButton id="Depart" value="DEPART" action="#{departure.updateDeparturePersonnel}"/>The "personnel" is the List that builds the xxx.jsp and it is also the List I try to access after the button in the xxx.jsp is clicked. Here in my configuration file:
<managed-bean>
<managed-bean-name>arrival</managed-bean-name>
<managed-bean-class>processAction.DepartureManagementBean</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
<managed-bean>
<managed-bean-name>departure</managed-bean-name>
<managed-bean-class>processAction.DepartureManagementBean</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>when the updateDeparturePersonnel() method is called in the DepartureManagementBean.java, I got run-time ClassCastException. And I am unable to see the problems in my code.

Is there a simple way to retrieve the data from a resultset using JavaBean?

I have a result set from a select * from users where userid = xxx statement. However, at the moment I have had to hard code the remainder of the code to get the data from each column as I need the column name as well as its data.
I had read somewhere using java beans and reflection it is easier. But i do not know know how.

Well, it is not really simple. But there are Open Source components to simplify it for you. See e.g http://www.must.de/Jacompe.htm - de.must.dataobj.DataObject and its subclasses. Feel free to contact me if you have any questions: [email protected]

Java Program in MDM to call a standard java class

Hi All,
In MDM- GDS, (Global Data Synchronization), we have a scenario where, once we register the Items , it will be transported to a Data Pool called 1SYNC through SAP PI.
There is a standard Java PRoxy(Kind of java Class) in MDM, which will be triggered once we register the Item in MDM-GDS.
That Java Proxy will send the Item INfo as a XML message to PI.
So we would like to know whether its possible to automate this process.
Like,Writing a new Java Program which will check all the new items and trigger the Java Proxy and send these items as XML Messages to PI.
I m new to MDM. So it would be really helpful, If i could get some inputs on this. Like, is it possible in MDM. If so, how?

Aarthi,
you can acheive this from MDM itself, and need not to write any Java proxy.
you may consider following logic.
Create a field with the Name Status and Initilize it with Value "new". Now define syndicaiton Map to syndicate records which holds value "new" in the status field. define a workflow with syndication step, using maps defined earlier. After syndication step, execute an assignment to change Status field value from "New" to "Syndicated".
Revert back if any question.

Using RAW in Jave Bean to store data in Oracle 8i database

I have a question about using RAW in java program to read write data in Oracle database. Is there any sample with key information for me to refer to? Your help will be appreciated.

I have a question about using RAW in java program to read write data in Oracle database. Is there any sample with key information for me to refer to? Your help will be appreciated.
Jane Jane,
here is a code snippet provided by our QA team
hope it helps
Kuassi
1. Create the table:
"CREATE TABLE rawtable (key VARCHAR2(30), rawcol RAW(2000), longrawcol
LONG RAW, moredata VARCHAR2(100))"
2. Write the data:
byte x[] = {1,2,3,4,5};
byte y[]= {6,7,8,9,10};
PreparedStatement pstmtR =
conn.prepareStatement("INSERT INTO rawtable (key, rawcol,
longrawcol, moredata) VALUES (?, ?)");
pstmtR.setString(1, "rawcol data");
pstmtR.setBytes(2, x);
pstmtR.setNull(3, Types.LONGVARBINARY);
pstmtR.setString(4, "Here's some more data!");
pstmtR.execute();
pstmtR.setString(1, "longrawcol data");
pstmtR.setNull(2, Types.BINARY);
pstmtR.setBytes(3, y);
pstmtR.setString(4, "Here's some more data!");
pstmtR.execute();
pstmtR.setRAW(1, RAW_obj) can be used to insert the RAW data.
You can also use setBinaryStream to insert RAW data:
CallableStatement cstmt =
conn.prepareCall ("begin insert into rawtab values (?,?); end;");
cstmt.setBinaryStream (1, (java.io.InputStream) new
ByteArrayInputStream(rawbuf), rawbuf.length);
cstmt.setBinaryStream (2, (java.io.InputStream) new
ByteArrayInputStream(lrawbuf), lrawbuf.length);
3. Read the data:
InputStream is = null;
byte rawbuf [];
byte lrawbuf [];
ResultSet rset = stmt.executeQuery("SELECT rawcol, longrawcol FROM
rawtable");
// You can retrieve the data with the following methods
rawbuf = rset.getBytes(1);
lrawbuf = rset.getBytes(2);
RAW raw1 = rset.getRAW(1);
is = rset.getBinaryStream(column);
is = rset.getAsciiStream(column);
is = rset.getUnicodeStream(column);
When using CallableStatement:
((OracleCallableStatement)cstmt).registerOutParameter(1,
OracleTypes.RAW);

Query - Cannot Retrieve the Data / Result Set

Hello,
I'm trying to query a cube through the OLAP connection using Java and every time I try to execute a query an exception is thrown stating "Cannot retrieve the data set" or "Cannot retrieve the result set" depending on how I'm doing the query. I've tried to execute the query both through the use of an IBIQuery and IBICommandProcessor object as well as directly through the IBIOlap connection via an MDX statement and both methods produce the same exception. If anyone can shed some light on why exception is being thrown it would be greatly appreciated.

please help me ... The question has nothing to do with 'getting' data from excel and certainly not with putting it into MySQL.
The stack trace specifically tells you that your connection string is wrong.
It also tells you which connection string is wrong.
Which you can use to determine specifically which one is wrong. And which you did not provide that info to us.
