MDM java api search on Main table

Hi All,
I am developing MDM Web dynpro custom application using MDM java API 2. I am having difficulty while searching on main table by date field. The fields type in MDM as u201CTime Stampu201D how I make my search constraints. Please point me if there is any tutorial or sample code.
Thanks
John.

Hi John,
Try using the following code snippet.
TableId tableId = schema.getTable("Products").getId();
FieldId fieldId = schema.getField("Products", "Update_Date").getId();
FieldSearchDimension searchDimension = new FieldSearchDimension(fieldId);
Calendar cal = Calendar.getInstance();
cal.set(2009, 11, 24);
DateTimeSearchConstraint dateConstraint = new DateTimeSearchConstraint(cal, DateTimeSearchConstraint.GREATER_THAN);
Search search = new Search(tableId);
search.addSearchItem(searchDimension, dateConstraint);
Here "Products" is the name of the table on which the search is done. "Update_Date" is a field of type Timestamp. I've hard-coded the date currently. You can use the various Date constructors to set the date dynamically.

MDM JAVA API to enter value into field of type date

Hi All,
I am having an input field in a typical Dynpro application where a date would be entered.I want to enter the date in my MDM table in a field of type "Date".Do you have any idea about MDM JAVA API's I need to do this.Also how can I do this ?
Thanks
Vinay

Hi,
Web Dynpro shall return you a type Date field. For Value, you shall have to pass SystemTime Object.
Just get the substring of Date.toString() and convert them to Integer ..
So a typical date would look like yyyy-mm-dd (eg: 2006-10-19) and not yyyymmdd.
SystemTime st = new SystemTime();
st.setYear( Integer.parseInt(Date.toString().substring(0,4));
st.setMonth ( Integer.parseInt(Date.toString().substring(5,7));
st.setDate ( Integer.parseInt(Date.toString().substring(8,10));
A2iField date = new A2iField("fieldname", new Value(st));
Hope that helps..
Regards,
Tanveer.
Please mark helpful answers
Note: The above mentioned code is not pasted from any editor..So might contain syntax error..

Attachments using MDM java API

Hi
How to store attachments in MDM repository using MDM java API.
Could you please suggest us.
Thanks
Sowmya

Hi Sowmya,
You can store attachments using MDM Java API. You can use the following piece of code.
BinaryBlobRecord record2 = RecordFactory.createEmptyBinaryObjectRecord(tableID);
//Attachment to be saved
String filePath = wdContext.currentContextElement().getVa_Resource().getUrl(0);
IWDResource resource = wdContext.currentContextElement().getVa_Resource();
FileInputStream stream = (FileInputStream)resource.read(true);
int length = 0;
while(stream.read() != -1)
     length++;
byte[] b = new byte[(int) length];
stream.read(b);
stream.close();
record.setName(new StringValue("filename"));
record.setOriginalName(new StringValue("filename"));
record.setHasOriginal(new BooleanValue(true);
RetrieveGroupTreeCommand groupTreeCommand = new    RetrieveGroupTreeCommand(wdContext.currentContextElement().getVa_ConnectionStr());
groupTreeCommand.setSession(wdContext.currentContextElement().getVa_SessionID());
groupTreeCommand.setGroupType(GroupTypes.DATA_GROUP_TYPE);
groupTreeCommand.execute();
//Set data location and data group ID
record.setDataLocationId(new GroupNodeId("GN2"));
record.setDataGroupId(new GroupNodeId("GN2"));
record.setBinary(new BinaryValue(b));
CreateRecordCommand createRecComm =
                         new CreateRecordCommand(wdContext.currentContextElement().getVa_ConnectionStr());
createRecComm.setSession(wdContext.currentContextElement().getVa_SessionID());
createRecComm.setRecord(record);
createRecComm.execute();
//Link this record to the main table record
Record QRec = RecordFactory.createEmptyRecord(mainTable);
//Setting the above created record in main table record object
QRec.setFieldValue(attachmentField, new LookupValue(record.getId()));
CreateRecordCommand createRecComm =
                    new CreateRecordCommand(wdContext.currentContextElement().getVa_ConnectionStr());
createRecComm.setSession(wdContext.currentContextElement().getVa_SessionID());
createRecComm.setRecord(QRec);
createRecComm.execute();
Now the main table record is created with an attachment.
Hope this helps you.

1) can you please share the required documents on the same. how to start working on this by using MDM JAVA APIs in webdynpro for java
2) what are the JARs files are required and how to integrate those jar files into webdynpro for java application.
3) is there any SDN help on MDM JAVA API with webdynpro for java? . can you please send the link on the same.
4) can you please help by providing sample code on how to use JAVA APIs for retrieving,deleting,inserting and Updating the data in the database.
if anybody helps on the same then it is the great help to me.
points are always rewardable...
Regards
Suresh babu

Hi Suresh,
You can have the MDM JAVA API javadocs from the link
http://help.sap.com/javadocs/MDM/SP06P2/index.html
There you can see a package named com.sap.mdm.examples.The classes in it contains some examples using which you can start understanding the code.
You need to have MDM JAR files for it. And these JAR files to be used at build time can be added to the project thru :-
Right click on project-> properties->Java Build Path - > Add external JARs
At run time you can add them the reference in
Right click on project-> properties->web dynpro references->library reference.

Hi Nitin,
Thanks for the prompt Response.
Even I am guessing that its becose of Connection pool.
I am destroying session as follows
               DestroySessionCommand destroySessionCommand =
               new DestroySessionCommand(p_pool);
          destroySessionCommand.setSession(p_repsession);

               } catch (CommandException e) {
                    e.printStackTrace();
But I didnot find any method by which i can close realsse connection from connection pool.
It would be great if you can help me how close or realese those connection.In MDM Console i am able to see those sessions even after destroying them.

Inetgrating MDM Java API's with Java proxies on XI side

Hello friends
Can anyone help me on integrating MDM JAVA API's used for talking to MDM Server and the Javaproxies we generate from the XI side.I am having an application class inside the Java API's (it contains the main function)which triggers the functionality on the MDM side.But how to trigger it from the Java proxies side??I can get the different fields that I have to send in the impl.java program of my generated proxy,but how to trigger the MDM Java API's from inside this.Also there is one problem I needed to pass the datatype fields from the Javaproxy(XI)side to the CRUDMAINTABLERecord program..Since importing the javaproxy package is giving me an error(I don't know why)I don't know how to pass these datatypes to the CRUD program.Please help me out on this urgently.Thank you all in advance.

MDM JAVA API ERROR

Hi,
we are calling mdm java methods from webdynpro code.
We are executing java successfully from main method. but,when we try to execute it from webdynpro we are getting the follwing error.
What this exception means to mdm?
Unexpected exception:Unexpected field type -1

Hi Ramu,
the specified exception may be due to wrong fieldCode or Table Code in MDM Java API which you are using ;
As per my understanding, you might be searching for MDM data from WebDynpro,so look at your resultset or Search object building , some where you coded with wrong FieldCode;
problem may not be at your WebDynpro but may be at your MDM JAVA API Code;
give detail information on your question, if you have still problem on that;

Java tutorial - helps, problem is i don't understand the API

I don't understand the JAVA Tutorials or the API

Take two steps back.
Buy a book on basic Java Programming. You need to understand the concepts behind programming before you should start reading the API.
But kudos for at least trying to read the API.
Now look at the column on the left, and follow the link called [url http://developer.java.sun.com/developer/onlineTraining/] Tutorials
and then the link titled [url http://java.sun.com/docs/books/tutorial/index.html]The Java Tutorial (Java Series).
And finally read through the sections starting with [url http://java.sun.com/docs/books/tutorial/getStarted/cupojava/index.html]Your First Cup of Java.
Then once you have been through all of that, come back and ask for clarification
on any specific points that you have trouble understanding.
Finally (Because the Finally always gets executed) Try taking a class in java programming.
