CMP and Serializable fields

Hello,
I would like to declare a field in an CMP Entity Bean to hold Serializable objects.
It seems to work fine for primitive types and arrays of them but I get an exception as soon as I try to set the field via the bean remote interface with an instance of a user created class implementing Serializable :
com.evermind.server.rmi.OrionRemoteException: Method invocation failed (Invalid return command: 6)
     void com.evermind.server.rmi.RMIConnection.EXCEPTION_ORIGINATES_FROM_THE_REMOTE_SERVER(java.lang.Throwable)
          RMIConnection.java:1499
     java.lang.Object com.evermind.server.rmi.RMIConnection.invokeMethod(com.evermind.server.rmi.RMIContext, long, long, java.lang.reflect.Method, java.lang.Object[])
          RMIConnection.java:1452
     java.lang.Object com.evermind.server.rmi.RemoteInvocationHandler.invoke(java.lang.Object, java.lang.reflect.Method, java.lang.Object[])
          RemoteInvocationHandler.java:55
     java.lang.Object com.evermind.server.rmi.RecoverableRemoteInvocationHandler.invoke(java.lang.Object, java.lang.reflect.Method, java.lang.Object[])
          RecoverableRemoteInvocationHandler.java:22
     void __Proxy1.setBehaviour(java.io.Serializable)
     void cern.laser.business.test.ConsoleConfigurationEntityEJBClient.main(java.lang.String[])
          ConsoleConfigurationEntityEJBClient.java:27
The class looks like :
public class MyClass implements java.io.Serializable
private String s;
public MyClass ()
s = new String("ciao ciao");
The corresponding database column is defined as BLOB.
Thanks for your help,
Francesco.

Can any body tell me the relation between cmp and cmr
fields in CMP beans
Thanks in Advance
SudhakarWe could say:
If an Entity EJB is a record of a database table, a CMP is like a simple table column and a CMR represents a table column refering to a Foreign Key.

Jquery and serialize / passing variables

I already put this question on the jquery forum but noone responded. My question is about jquery.
I have this image gallery, people can drop and drag pictures, the idea is they can determine theirselves the order in which images are shown on their website.
I have the sortable part, but I don't know how to pass the new order to the next page that should contain a query that updates the ordernumber for each item.
My code:

     <script src="scripts/jquery-1.6.2.min.js" type="text/javascript"></script>
    <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.16/jquery-ui.min.js" type="text/javascript"></script>
    <script src="http://jquery-ui.googlecode.com/svn/tags/latest/external/jquery.bgiframe-2.1.2.js" type="text/javascript"></script>
    <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.16/i18n/jquery-ui-i18n.min.js" type="text/javascript"></script>
,!--- the actual sortable image gallery --->
<ul id="ulsortable">
    <cfoutput query="items">
        <li id="ID_#T_items_autoID#">
            <CFIF #T_items_img1# IS NOT 0>
                <img src="../#session.foldername#/galleries/#T_items_itemid#_thumbsitemanager.#T_items_img1#" alt="Click here to update" border="0" width="125" height="125">
                <CFELSE>
                    <img src="layoutimg/no_picture_available.jpg" alt="" width="125" height="125" border="0">
                </CFIF><br>
                <CFIF #T_items_title# IS NOT "">#left("#T_items_title#","15")#</CFIF>
        </li>
    </cfoutput>
</ul>
<script>
    $(function() {
        $( "#ulsortable" ).sortable();
        $( "#ulsortable" ).disableSelection();
        $('#frm-sort').submit(function(){
            var sort_serialized = $("#ulsortable").sortable("serialize");
    </script>
<form action="#request.site.webroot#/actions/act_writeneworder.cfm" method="post" id="frm-sort">
<input type="submit" name="save" id="save" value="save" />
<input type="hidden" name="sort_serialized" id="sort_serialized" value="" />
</form>
When I use this and go to the next page thrugh submit button I get the error that sort_seriallized is an empty string. i must be doing something wrong. It has been 3 days i am on it:-)

If anyone is interested, here is the working code.
Make sure to include the right jslibraries
Make your stylesheet so you have an unordered list that looks like an image gallery:
<style>
         ul
            width                : 715px;
            list-style-type    : none;
            margin              : 0;
            padding             : 0;
        /* float & allow room for the widest item */
          ul li
            float                 : left;
            width                : 136px;
            height              : 165px;
            margin              : 2px;
            text-align          : center;
            border              : 1px solid gray;
           /* stop the float */
          br
            clear            : left;
          /* separate the list from subsequent markup */
          div.wrapper
            margin-bottom    : 1em;
    </style>
Then the jquery script:
<script type="text/javascript">
        $(document).ready(function(){
// sortable makes the ul drag and drop
            $("#ulsortable").sortable();
// create variable that will be submitted with form
                $("#frm_sort").submit(function(){
                    var order = $('#ulsortable').sortable("serialize");
                    $('#order').val(order);
    </script>
Ouput the listitems:
<ul id="ulsortable">
    <cfoutput query="items">
        <li id="myprimarykey_#T_items_autoID#">
                 <img src="../#session.foldername#/galleries/#T_items_itemid#_thumbsitemanager.#T_items_img1#" alt="Click here to update" border="0" width="125" height="125">
                <br/>
               <CFIF #T_items_title# IS NOT "">#left("#T_items_title#","15")#</CFIF>
        </li>
    </cfoutput>
</ul>
Finally the form with submit button and hidden field that passes variable:
<form action="actions/act_writeneworder.cfm" method="post" id="frm_sort">
      <input type="hidden" name="order" id="order" value="" />
      <input type="submit" name="save" id="save" value="Save new order" />
</form>
The page that handles the serialize and database update:

    <cfset idlist = ReReplaceNoCase( form.order, "(&)?myprimarykey\[\]=", ",", "all" )>
    <cfset position = 0>
    <cfset pk = 0>
<cfloop list="#idlist#" index="pk">
      <cfset position++>
    <cfquery name="writeneworder" datasource="#request.dba#">
        UPDATE T_items
            SET T_items_order = <cfqueryparam value="#position#" cfsqltype="CF_SQL_INTEGER">
             WHERE T_items_autoID = <cfqueryparam value="#pk#" cfsqltype="CF_SQL_INTEGER">
    </cfquery>
</cfloop>
<cflocation url="#request.site.webroot#/item_choose_cat.cfm?currentopic=changeorder" addtoken="no" />
As I couldn't find anywhere a full working exemple I decided to post this code, hope it helps you.

DSO - What key fields and data fields in dso

Hi experts,
I need to create a dso in between the cube and 2 data sources(2lis_11_vaitm, 2lis_12_vcscl) to stage the data. My question is: what key fields and data fields to choose for the dso? is there a standard dso to copy? please explain in detail the model to set up, whether to connect both the ds's to dso and then to cube or one ds to dso and the other to the cube. more details will help.

Check this for standard DSO:

Infoset Join condition on Key feilds and data fields

Hi Guys,
I have a requirement to biuld the Info set with join conditon on two DSO's the info objects which i am using in the JOin condition are defined as data fieds in one DSO and defined as key fields in another DSO, is it possible to define join condition on key fields and data fields.
The two info objects are
                       0AC_DOC_NO
                       0ITEM_NUM
These two info objects are defined as data fields in DSO :   0LIV_DS1   Invocie verificaion
                                                        key fields in DSO:    0FIAP_0o3 FI AP Line Item
Please suggest me is it possible to define join the condtion on the data fields and key feilds.
Thanks

Hi
yes you can create join, you will get any issue in reporting level.
example: Say i want to create Info Set on 0MATERIAL and Sales DSO.
In 0MATERIAL Info Object it is key filed, but in my DSO 0MATERIAL is data field.Still we can create
Creation of join is dependent on fields common in your source objects.
check out the below document

Key fields and data fields in a DSO ??

i have a question regarding key fields and data fields in a Standard DSO...
i am using 2 datasources to build a open sales report 2LIS_11_VASTH and 2LIS_11_VASTI i am pulling in data from these 2 data sources to a DSO and i am wondering what infoobjects should be in the key fields and data fields .....does this reflect back to table VBUK and VBUP tables and does the key field in the DSO have to be the key fields in VBUK and VBUP tables ???? or what really should be included as key fields and data fields ????
please help....

If you look at the various SD tables, VBELN and POSNR are commonly used as the document number and document line item.
For VBAP and VBUP, it's referring to the Sales Order Line Item with the columns VBELN and POSNR as the key for both tables. However, if you look at the LIPS table, which is the Delivery Line Item table, it too has VBELN and POSNR as the key. Likewise, the VTTP table, which is the Shipment Line Item table, also has VBELN and POSNR as the key.
While using RSOSFIELDMAP as a map is a fairly good "rule of thumb", it still needs to be used with a level of skepticism.

Prerequsites for deciding Key fields and data fields

Hi
I would like to know the criteria to decide upon KEY fields and Data fields for an infoprovider.

Hi,
What is a Key field in a Database and How should I choose one?
Keys are crucial to a table structure for many reasons, some of which are identified below:
They ensure that each record in a table is precisely identified.
They help establish and enforce various types of integrity.
They serve to establish table relationships.
Datafields may be Charecteristics and it may be keyfigures

Key Fields and Data Fields in ODS

Hi Guru's ,
Can u Explain what are Key Field's and Data Field's in ODS,and How they work.
Thanx in Advance.

Hi Pradeep,
An ODS key fields forms a unique combination of chars according to which data in the ODS will be summed up. Data fields are additional fields, chars or key figures.
For example, you have the following key fields:
Doc No, Doc line item (item no in the doc) and you load the following data:
Doc# Item# Amount CALDAY
1234 1        100       26.09.2005
1234 1        150       27.09.2005
1234   2        300      27.09.2005
1235   1        400      27.09.2005
The first two rows with the same key fields (1234-1) will be aggregated and into ODS will go amount of 250.
What I said is true if for Amount key figure the Add option is set.
But if you set an Overwrite option, then the second record will overwrite the first one and only amount of 150 will go to ODS!
But if CALDAY is also a key field, then into ODS will go all records without any aggregation, because key fields combination is different for all records.
So, ODS key fields choice and KFs settings are very important for data aggregation in the ODS.
Best regards,
Eugene

Data fields and key fields

Hi,
Data fields and key fields are same as Characteristcs and key figures? Or they are diffrerent?
Thanks,
Radha

HI
Key Fields = Acts as Primary Key for The ODS like Primary of Tables in R3.
Data fields = Apart from Key fields We consider rest as data fields.
Ususally we use Characteristic info Objects and Dates in Key Fields and Key figures in Data fields.
It's decisive factor for overwriting property of ODS or DOS.
Hope this helps.

Chart report Condition fields and Data fields

Hi all,
i have tried chart report by adding two condion fields and one data field, the report is more meaning full in this scenario. the first condition field is taken as x-axis, the 2nd condition fields is taken as legend.
while adding more condition fields and data fields, i feel its not showing meaningfull data.
can anyone explain how the condition fields and data fileds are manipulated by crystal report.
i am using CR XI R2 Server.
Thanks
Padmanaban V

i am using Crystal Report XI R2 RAS Embedded in my server.
as we can add any number condition fields programatically using the method
ConditionField.Add(FieldObj), i would like to know how these fields are manipulated internally by the RAS server.
that means, what is the significance of condition fieldobject 1, condition fieldobject 2,condition fieldobject 3 etc...
if i add more than two condition fields , RAS Chart Report always returns 0 as legend value for all legends.
Thanks in advance

Identify key fields and data fields

Hi
i have datasource 0co_om_cca_9 .
i want build 1 DSO, how can i identify what are key fields and data fields to build DSO based on that datasource.

Hi sunnel,
The DSO are like 2-D database tables.
We use the technical keys here in counterpart to the business keys in Infocubes.
The key fields are the one based on which the records are identified uniquely in the database table.
And the data fields are the ones which are aggrgated or summarised or overwritten based on the value in key filed.
For example:
The ID no.s of the employees will be unique and it can be used as a key field.
The feilds like the Salary taken by the employee every month :"SALARY"
and the no. of leaves they taken: " NO. OF LEAVES" can be used as data fields.
So that the salary or the leaves taken by a particular employee can be aggregated based on her/his ID no.
The key fields in DSO doesnty mean Key figures.The key field means any unique key or a key based on which the records are sorted in the DSO
And key figures are the data fields.Some of the Characteristics can also be data fields in DSO.
Please give points if u r satisfied wit the information
Also let me know if u hav any doubt and if any thing is wrong.
Regards,
Kalpana M

Defining Key -field and data fields

Hi all
i have to define Key-Fields and data-Fields for a DSO(say DSO3).
DSO1 is a combination of DSO2 and DSO3..
DSO1 and DSO2 are SAP defined DSOs.
DSO3 is a User defined DSO.
my assumption:
   DSO3 has 30 fields
   DSO2 has 16 fields.
   can i create the DSO3 with remaining 14 fields which is there in DSO1?
   or i have to create the DSO3 with 30 fields(all DSO1 fields).
can any body explain....
Thanks & Regards
krishna

The problem is not how many fields you create where, the issue is where is the data is going to come from.
Since you data is going from DSO3 to DSO1and if the field is already getting populated in DSO1 from DSO2, then you don't have to worry about populating those fields again, unless and otherwise you want to overwrite them.
Remember any fields exist in both DSO3 and DSO2 which overlapping will be overwritten by the latest update.
Again, going back to your question, you should consider does your datasource has missing fields (14 of them).
thanks.

How to update a People and group field using a sandbox solution

Hi,
I am creating a sandbox solution for office 365 and creating a custom form using visual web part, which will allow users to enter data in a custom list.
And that list also have a user field. I am able to get SharePoint user field on the form (using javascript) which is searching for the user and get a value (working fine).
Issue: But I am not able to save the user value. Because to save user value I require web, UserID and login name, to construct SPFieldUserValue object or string in "111;#TestUser" format. Moreover that user should be present in
SiteUserInfoList.
I tried web.EnsureUser() but did not work under sanbox solution.
Can you please provide any pointer or workaround to the problem? I may be missing something here.
Thanks,
Himanshu

Hi,
According to your description, my understanding is that you want to update the people and group field in Sandbox solution.
In the sandbox solution, you can still use the web.EnsureUser() function to get the user information, see the thread below:
EnsureUser in sandboxed solution
In additional, there is a demo with your similiar requirement for your reference:
Using the People Picker Control in Sandbox Solutions / Office 365

Question on how to Hide the User Name, Password, and Domain fields in the MDT Wizard

MDT 2012 U1
Deploying Windows 7 via Offline Media (ISO) to MS Virtual PC's
I am looking on how to Hide the User Name, Password, and Domain fields which are prepopulated in the MDT wizard via the CS.ini (Not so concerned about the Domain field as I am User Name and Password)
We do need the Computer Name and OU fields to be seen, so skipping the wizard is not a option
The client just does not want these fields to be seen by the end users, they dont want them to even know the account name used for adding the machine to the domain, of course the password is not displayed but it must not be displayed either.
But since we use the fields they must still be fuctional just not seen.
Thanks.....
If this post is helpful please click "Mark for answer", thanks! Kind regards

You shouldn't have to edit DeployWiz_Definition_ENU.xml. You should only need to add "SkipAdminPassword=YES" to the CS.ini file and your authentication information.
Example:
[Settings]
Priority=Default
Properties=MyCustomProperty
[Default]
OSInstall=Y
SkipCapture=NO
SkipAdminPassword=YES
UserID=<MyUserID>
UserPassword=<MyPassword>
UserDomain=<MyDomain.com>
SkipProductKey=NO
SkipComputerBackup=YES
SkipBitLocker=NO
-Nick O.
Nick,
SkipAdminPassword=YES is for:
You can skip the Administrator Password wizard page by using this property in the
customsettings.ini.
I am hidding the Username/Password/and domain field in the computer name Wizard pane which is read from the cs.iniDomainAdmin=xxxxx
DomainAdminPassword=xxxxx
DomainAdminDomain=xxxxxx
JoinDomain=xxxxxx

Path and Name field in SPD 2010 Workflow for creating Doc Sets

Hi Guys,
Here's hoping you can help out and give a few pointers. I'm currently trying to implement what I thought was quite a simple workflow involving the creation of a Content Type (similar to Doc Set but with additional field) within an alternative library when
a new item is added to the current library.
Create Item in CaseFileLibrary (Output to Variable: CaseFile)
When running the workflow, I keep getting the following error:
"The workflow could not create the list item because the file name is either missing or invalid. "
It seems to be related to the 'File and Path' field within the 'Create New List Item' field mappings. For this I have tried the CurrentItem:Title as some other forums suggest and have also tried entering the URL path e.g. /subsite_name/library_name/CurrentItem:Title.
(as the name of the CaseFile (Doc Set) is going to be the same as the current item name)
If anyone has any suggestions, I would be truely greatful.
Luke

Hi Luke,
This error indicates there is an error in the workflow logic. Ensure that the file name entered in the Path and Name field is a valid file name. Common reasons for a file name to be invalid include a missing or incorrect file extension or a file/path string
that is too long and exceeds the allowable number of characters.
More information, please refer to :
Common error messages in SharePoint workflow development
For the URL that you used in the ‘Create New List Item’, whether the CurrentItem:Title is a lookup, not typed by yourself. If not, please type /subsite_name/library_name/, then lookup CurrentItem:Title, like the below, then save and publish the workflow,
compare the result.
In addition, please use another name for the name, compare the result.

Wendy
