Question finding methods or documentation on methods

Hi All,
Where I can find all the functions or methods like SAPBWGetDataProviderDimensions ? This one I found on help.sap.com.
Is there any good documentation on methods of classes like CL_RSR_WWW_ITEM_CHART...I can see classes methods of it using se84. but need more info.
ANy Ideas ?
Thanks in advance,
GSM.

Heider,
Thank you for your information.
Can I ask you one more question. I have one problem.
A variable screen has profit center varible. User will enter one value on the profit center variable. In the template there is a combo. Which shows a ZINFOOBject values of a particular profit center. When the template is open it shows a graph and table for all the values of the profit center. If user needs to view the graph and table on ZInfoObject they will change the value in the drop down box.
But my users are not happy with this. The way they want the solution is as soon as the webtemplate opens it show all the graphs for the number of values in the ZINFOOBJECT for a particular Profit Center.
Eg. User enters profitcenter1 and it has 10 values in the ZINFOOBJECT, then in the web template it should show 10 graphs. If user enters profitcenter2 and it has 20 values for the ZINFOOBJECT, then the template should show 20 graphs.
I am able to read each value within the profit center using the javascript. But I am unable to create the chart object in the javascript. I tried using document.write also.
ANy ideas how this can be achieved ? Is it achievable by BSPs ? I don't know much about BSPs....
Thank you very much for your input.
GSM.
The way I am showing on the information on a graph is,

Custom finder methods

I'm tring to deploy an Entity bean (CMP) with custom finder method that gets a parameter.
I encountered two problems :
1) defining the query in the deployment descriptor coased the app server to generate the a query without the where cloase - this was fixed by changing manualy the orion-ejb-jar.xml in the application-deployments directory.
2)the second, and yet unresolved problem, is that OC4J doesn't bind the parameter that the query uses during runtime. I'm recieving an ORA msg that claims that not all the parameters are binded.

see sample code
http://otn.oracle.com/sample_code/tech/java/oc4j/htdocs/oc4jsamplecode/oc4j-demo-ejb.html
also there should be a section in our documentation about cmp custom finder methods. oc4j attempts to generate custome finder methods based on home interface
<finder-method query="$empNo = $1">
<method>
 <ejb-name>EmployeeBean</ejb-name>
 <method-name>findByEmpNo</method-name>
 <method-params>
 <method-param>java.lang.Integer</method-param>
 </method-params>
 </method>
 </finder-method>

Finder Methods

Do I have to specify a Transaction Attribute for every finder method, other than Required attribute. Cause if i don't do this (leave the transaction attribute as it is) the verifier gives me "Transaction attribute must be specified for method findBy...."
Thanks in advance,
Ahmed

Thanks Lev, One questions is: I use the program over a network, if two clients try to mke the same operation at the same time, only one of them is serverd, the other will have an exception thrown to him, which is: TransactionRolledback Exception... Do u know how to fix this...
Thanx in advance...

Finder Methods other than by Primary key

How should the Finder methods other than by Primary
key in Container MB be implemented? In Bean class?
I did some search in archives to no avail.
Thanks!!
Sriram

I think it might be different on different app servers, at least until EJB 2.0 is implemented everywhere. I found a bit of info on the matter:

Finder method in Entity bean

how many Finder method in Entity bean i can write ?
look below...
public Account findByPrimaryKey(AccountPK key) throws FinderException,
RemoteException;
public Enumeration findByOwnerName(String name) throws FinderException,
RemoteException;here 2 finder methods are there.......i am asking how much freedom i have ? can write as many as finder method i wish ?
say, findXXXX() ?

my problem is on the signature of the find
method.
OK let me ask you some other way.
java DOC says
Each enterprise Bean has a home interface. The home
interface must extend the javax.ejb.EJBHome
interface, and define the enterprise Bean type
specific create and finder methods (session Beans do
not have finders).
look it says " finder methods "....right .
so i want to ask 2 question about this phrase . PLZ
do confirm me whether i am right or wrong.
fact 1. finder methods means you can write
any method name which starts with word find
and ONLY find
Example: findABCD( ) , findEFGH(),
findBLAHBLAH()...any thing starts with find[i]
are called finder methods...others are NOT.
is This fact correct ?
Yes.
fact 2. Is not it Strange that i need to
append some letters after the word find to
get a finder method name !! why not wrting a simple
method name ( say abcdfgrty () instead of
findXXXX() which will do the job ??You can... but it has to be called form a findXXXX() method :)
As such there is no problem in writng a
find_ANY_WORDS_HERE() to get a finder method but
problem is why i need to stick to the word
find and append some words after it
t to get a finder method ? if i had to do it
seriously then whats the role of the container ? how
w it is linking ?Once someone takes the pain of going through the EJB specs, he would not have a problem. Imagine each vendor using his own brains and the developer getting bugged with new features in each AS. EJB specs are flexible enough already :)

JPA 2.0 EntityManager.find method

As per the documentation, JPA 2.0 implementations like OpenJPA and EclipseLink can only accept a second parameter of type java.lang.Object primaryKey if one is using the EntityManager.find method.
Has anyone been able to pass a String as the second parameter? I'm interested to know if this is possible.

The type should match what you marked as the @Id in your entity; if the id field is of type String, you should be able to pass a String to the find() method.
I'm interested to know if this is possible.You know the best way to know is to try. If you want to test out things with JPA it might benefit you to look into a pure Java database such as HypersonicSQL. That way you can quickly setup a database environment without needing any additional software, plus with for example Hibernate's auto generation functionality you can let the database itself be generated from your JPA entities. Database driven unit tests are then very quick and easy.

Not able to reload the data from DB using finder methods

Hi all,

I am facing a weird problem while using finder methods.
I am using weblogic 8.1 SP3 and entity beans are CMP with DB concurrency.DB is oracle

<h4>Problem Description</h4>

I am having one session bean which internally interacts with my entity beans,
Now say my transaction is getting initiated in one of the session bean and I use some finder in it.


To make the problem more clear lets say my entity bean is loanBean with loanId as primary key.
Now say method A of session bean initiates the transaction and I use something like
 
LoanLocal loanLocal =loanLocalHome.findByLoanId(loanId);
 
Note that I am not using findByPrimaryKey method
 
now this method A calls some other method B on some session bean which is having Required as its transaction attribute.
 
But before the call of B some other thread or background process updates the DB for this loanId and commits,
 
now when I fire the same finder in method B I am still getting the old data, ie I am not getting the data which has been modified in DB and committed by some other thread, I still get the old data and when I tried to generate the SQL queries which weblogic is firing, I see
it fires the SQL for every finder other that findByPrimaryKey.
 

Now my problem is I am getting the old data only and I need the new updated data of DB. isolation-level of DB and beans is READCOMMITTED.
Note:: I cant use new transaction to read the data.

 
And I couldn't understand that when weblogic is firing query for every finder then why it should not refresh the data in its cache. Is there any way to disable this kind of caching and say that everytime when i use finder just go to DB and get me the last committed data.

 
Any help in this regard would be very helpful to me.
 
Thanks and Regards
 
Manish Garg.


Hi,
In my understanding, cache is not involved in this scenario. As you
observed, the container fires sql every time when you invoke this finder.
So, it should just give the result that it got from the DB. Is there a
possibility that the DB is using repeatable_read or serializable for
isolation level?
You can debug further by doing couple of things -
1. Instrument the code in the generated RDBMS java file for the entity bean
(if you use -keepgenerated option for weblogic.ejbc, u can get the source of
this file). This class will have the implementation for ejbFindByLoanId. You
can just print the result set data after the query is fired.
2. Try the same scenario without the ejb container. Like, write a jsp which
will start a user tx and fire the query twice such that there is an update
between the two queries. Note that, you need to use a TxDataSource to get
the JDBC connection so that it will be tx aware.

How do I use the find method to find multiple items in a single paragraph?

I am desigining a script to find any instances where ctrl+b and ctrl+i are applied to body text and then replace those character format overrides with Italic or Bold chartag. Here's what the script is supposed to do:
put the find method in a while loop that searches for character format overrides.
If a character format override is found, pass the text range returned by the find method and the CharPropsChange flag to the GetTextForRange method.
Use a boolean compare between the idata of the text item to the character angle and character weight constants.
Whichever boolean evaluates to true, then use the SetTextProp method to set properties of the text range to the properties of the italic or bold character tag.
This script does work on the first character format override found however it ignores any other overrides in the same paragraph. The cause of this is that the while loop updates the text loc that the find method uses to the next paragraph in flow. I suspect that i need to add an inner loop that goes through all the text in a single paragraph, where at teach iteration the text loc used by the find method is based on the same paragraph but the offset is modified. I am just not sure how to do that.
function removeOverrides (pDoc)
    var vDocStart = pDoc.MainFlowInDoc.FirstTextFrameInFlow.FirstPgf;
    var vBoldFmt=getCharFmt (pDoc, 'Bold')
    var vItalicFmt=getCharFmt (pDoc, 'Italic')
    initFA_errno ();
    while (FA_errno==Constants.FE_Success)
        var vTextLoc = new TextLoc(vDocStart,0);
        var vFindParams=findOverrideParams (pDoc);
        var vTextRange=pDoc.Find(vTextLoc,vFindParams);
        if (vTextRange.beg.obj.ObjectValid())
            var vTextItems=pDoc.GetTextForRange (vTextRange, Constants.FTI_CharPropsChange)
            if (vTextItems.length==!0 )
                if (vTextItems[0].idata==Constants.FTF_WEIGHT)
                   pDoc.SetTextProps (vTextRange, vBoldFmt.GetProps())
                if (vTextItems[0].idata==Constants.FTF_ANGLE)
                   pDoc.SetTextProps (vTextRange, vItalicFmt.GetProps())
                } else (Log (vLogFileName, '\nERROR: No items were found in the text format array but format override was found: '+pDoc.Name))
        vDocStart=vDocStart.NextPgfInFlow;
function findOverrideParams (pDoc)
    var vFindParams = AllocatePropVals(1);
    vFindParams[0].propIdent.num = Constants.FS_FindObject;
    vFindParams[0].propVal.valType = Constants.FT_Integer;
    vFindParams[0].propVal.ival = Constants.FV_FindCharacterFormatOverride;
   return vFindParams;

Hi Rick,
Well, following up on the previous posting, I actually did figure out how to make it work but it seems rather inefficient. I can insert a new paragraph right after the paragraph that has the table anchor but when i cut the table, i also cut the paragraph i just created. So to get around that, I create two paragraphs, so that there will be one paragraph left after i do the cut and that is the paragraph that I paste the table into. Once the table is pasted into the new paragraph, I delete the other paragraph that I created.
Here's the updated code from the for loop:
var vTbl = vDoc.GetUniqueObject(Constants.FO_Tbl, vTextItems[i].obj.Unique);
var vAnchorPgf=vDoc.NewSeriesPgf (vTbl.TextLoc.obj)
var vAnchorPgf2=vDoc.NewSeriesPgf (vAnchorPgf);
var vAnchorTextLoc=new TextLoc (vAnchorPgf2, 0);
var vTblTextRange=new TextRange ();
vTblTextRange.beg.obj=vTbl.TextLoc.obj;
vTblTextRange.beg.offset = vTbl.TextLoc.offset;
vTblTextRange.end.obj=vTbl.TextLoc.obj;
vTblTextRange.end.offset = Constants.FV_OBJ_END_OFFSET
vDoc.TextSelection=vTblTextRange;
vDoc.Cut (0);
vTblTextRange.beg.obj=vAnchorTextLoc.obj;
vTblTextRange.beg.offset = 0;
vTblTextRange.end.obj=vAnchorTextLoc.obj;
vTblTextRange.end.offset =0;
vDoc.TextSelection=vTblTextRange;
vDoc.Paste (0);
vAnchorPgf2.Delete();

How to add a finder method in the container manager Bean in the weblogic6.1

in the environment jbuilder6 andweblogic6.1,use container manager entity Bean,it can automatic generate the findAll() method,I want to add a new method to find an element in the home interface,such as findByName(),name is a element of a table of the database.in the weblogic-cmp-rdbms-jar.xml,this is part of the fiile:
<finder>
<finder-name>findAll</finder-name>
<finder-query><![CDATA[ (= 1 1) ]]></finder-query>
</finder>
<finder>
<finder-name>findByName</finder-name>
<finder-param>java.lang.String</finder-param>
<finder-query><![CDATA[ (=name $name) ]]></finder-query>
</finder>
It can successfully compile the findAll(),but it is wrong when compile the findByName(),as follows
"www.ejbgrpx": Method Name: findByName
"www.ejbgrpx": Invalid specifications for a WebLogic RDBMS CMP EJB.
"www.ejbgrpx": ERROR: Error from ejbc: weblogic.ejb20.cmp11.rdbms.finders.IllegalExpressionException:

"www.ejbgrpx": Finder Expressions: ()
"www.ejbgrpx": Could not parse WLQL expression: (= name $name) null
"www.ejbgrpx": ERROR: ejbc found errors
thank you

The finder methods that you are referring to are only simple finder methods. If you would like to add specialized finder methods, you can make your entity bean with bean managed persistence and not container managed. If you are using EJB 2.0, your entity bean with container managed persistence can use EJB QL for finder methods. You can search for this topic and/or download the EJB 2.0 specifications
Hope this helps

CMP Entity Bean with ejb-ql finder methods and INFORMIX database

Hi,
I have some CMP Entity Beans with finder methods defined in ejb-ql. In my ejb-jar, within <entity> definitions I have something like:
 <entity>
 <abstract-schema-name>BeanName</abstract-schema-name>
 <cmp-field><field-name>fieldOne</field-name></cmp-field>
 <cmp-field><field-name>fieldTwo</field-name></cmp-field>
 <query>
 <query-method>
 <method-name>findAll</method-name>
 <method-params></method-params>
 </query-method>
 <ejb-ql>SELECT OBJECT(o) FROM BeanName o</ejb-ql>
 </query>
 <entity>
And in persistent.xml:
<db-properties>
 <data-source-name>datasource_name</data-source-name>
</db-properties>
<entity-bean>
 <ejb-name>BeanName</ejb-name>
 <table-name>table_name</table-name>
 <field-map key-type="NoKey">
 <field-name>fieldOne</field-name>
 <column><column-name>column_one</column-name></column>
 </field-map>
 <field-map key-type="NoKey">
 <field-name>fieldTwo</field-name>
 <column><column-name>column_two</column-name></column>
 </field-map>
 <finder-descriptor>
 <method-name>findAll</method-name>
 <method-params/>
 </finder-descriptor>
Once deployed, on server side, I can found a java source file (with corresponding compiled class file) in path:
j2ee/cluster/server0/apps/companyName/MyEARApp/EJBContainer/temp/temp38837373733/route/to/package/
with names:
BeanName0_0pm.java
BeanName0_0PM.class
and the generated java file contains this code:
public java.util.Enumeration ejbFindAll() throws javax.ejb.FinderException, javax.ejb.EJBException {
 TransactionContext tc = pm.getTransactionContext();
 Connection conn = null;
 PreparedStatement pSt = null;
 ResultSet ejb_rs = null;
 int status = javax.transaction.xa.XAResource.TMSUCCESS;
 try {
 conn = pm.getConnectionForFindMethod();
 pSt = conn.prepareStatement("SELECT \"O\".\"COLUMN_ONE\",\"O\".\"COLUMN_TWO\", FROM \"TABLE_NAME\" \"O\"");
 ejb_rs = pSt.executeQuery();
I'm trying to call this method but it throws a SQLException when preparing the statement.
It seems that Informix does not like this SQL syntax because of upper case names, doble quotes on table alias, or something else.
When editing persistent.xml in netweaver, I can define the element <datasource-vendor> as ORACLE, SAPDB, MS_SQL_SERVER, DB2_UDB_AS400 or DB2_UDB_OS390 but INFORMIX is not an accepted value.
Is there any way to define how this SQL query is build?
Thanks in advance.

The return type of the finder method defined in the remote home interface is either the entity bean's remote interface or a collection of objects implementing the entity bean's remote interface. The return type of the finder method defined in the local home interface is either the entity bean's local interface or a collection of objects implementing the entity bean's local interface

More than one entity found for a single-object find method

Hi everyone...
I have this error when my webservice is running..I don't know what it means and what would be the best solution..
<pns:message>More than one entity found for a single-object find method.</pns:message>
it throws an Exception..
Thanks!

= More than one row found in a DB with the "unique" key supplied...
Your method is returning an object where it should return a collection ?

Finder method in container-managed entity bean

Finder method of a container entity bean is taking the primary key class object of another entity bean. How to map this in the xml descriptor file weblogic-cmp-rdbms.xml for this type of beans.
I am trying to deploy the jasmine computer store of Mastering EJB by EdRoman.
I couldn't write the deployment file weblogic-cmp-rdbms.xml for Order Entity bean which uses CustomerPK as an argument in its finder method.
Please tell me how to write this. I am trying on weblogic 5.1
Thanx in advance
Srivatsa

hello,
in container managed persistence, you specify on your xml file the name of your table. so the primary key you want to use have to be a foreign key in your table. otherwise i don't think that you can use a container managed persistence.

Using wildcards in custom find methods with CMP beans

Hi,
I'd like to create a custom find method called findByName which accepts a string. I'd typically want to use the string in a '%<name>%' scenario, where the user needn't type in the whole name. Does anybody know what the partial query should look like? I'm not sure how to concatenate the '%' symbol to the string taken in.
Thanks in advance
Gillian

Gillian-
Bind variables are of the form $1, $2, etc., so try using a query stmt like this:
select * from YOURTABLE where name like '%$1%'

Problem when creating CAF Entity Service finder Methods

Guys,
Can any one please suggest me appropriatly to the below problem.
I am using NWDS 7.06. I have no problem when creating CAF project, Application Service and Entity Service even.
But in the Entity Service:
1. Add a string or longtext attribute.
2. try to create a custom finder method in operations tab, during that operation i am not finding the attribute which i have created in step1.
That means i am not able to create the my own finder methods with parameters.
I was able to do that in some version long ago but i have forgotten that NWDS version.
summary of Problem Is: " Cannot create custom methods with custom parameters in Entity Service"
Can you please suggest me the right version or a solution to this problem on urgent basis please.
I promise you that i will give you full points to you who ever gives me the right solution.
Please mail your suggestions to [email protected]

Guys,
I have solved the problem successfully. Thanks for your attention.
