Relationship of Jar within Jar
I have a project that uses kxlm2.
To this point in development I have included the source for kxml2 in my project hierarchy and compiled it along with my code, packaged it, ran/tested it, etc. Everything works.
However, I don't want to compile KXML2; I just want to include the kxml2.jar distro in my projects JAR file and be able to use it from my classes.
Is this as simple as including kxml2.jar in my jar or do I need to add it to the manifest? Do I need to explicitly load kxml2.jar within my app or does this happen magically?
Can someone please put me on the path to enlightenment. In the mean time I will continue to dig through the docs.
Thanks.
Java's standard classloaders will not load classes from a jar that is itself within another jar.
You can write a custom classloader to do that, or use a 3rd-party product (one is OneJar), or just use the kxml2 jar from your jar by adding a ClassPath: parameter to your jar's manifest file. Refer to Java's jar specification for information on the last option.

JDeveloper Unilateral relationship ejb-jar.xml verifying error
I am huge difficulty with tables that have relationships mapping in one direction (unilateral).
If I give you a really basic scenario of table Emp which has Employee information and a Dept_no foreign key. I also have a table Dept which has department info and includes it's primary key of Dept_no.
When dragging and dropping tables from the Oracle Database onto the UML Diagram (OC4J container), the relationships automatically configure as bilateral. The ejb-jar.xml builds and the verifying Enterprise Beans verifies OK. If I select the relationship on the diagram and change it to be unilateral from Employee -> Department, it will still compile the EJB related source, but the ejb-jar.xml file will no longer verify the Enterprise Beans.
Now there have been a million ways that I have tried to get this simple example to work.
Here's my ejb-jar.xml and the orion-ejb-jar.xml:

that's probably all the relevant information.
As I said if I can't map relationships unilaterally from Oracle tables, then that is a huge issue for our project.
Any Help, would be fantastic - THANKYOU.

When i add CMR between 2 CMP, it show ORA-00904
i create 2 "CMP from table" without foreign key. i can create both instance by home.create() . after i add CMR between both. i can create master but can't create detail. when i create the detail, it show ORA-00904.
anyone can help me?
master table is
CREATE TABLE KAY_TMP_1 (
ID VARCHAR2 (2) NOT NULL,
KAY_NUM NUMBER (9,2),
KAY_NAME VARCHAR2 (10),
KAY_DATE DATE,
PRIMARY KEY ( ID ) ) ;
detail table is
CREATE TABLE KAY_TMP_2 (
ID2 VARCHAR2 (2) NOT NULL,
SUB_ID2 VARCHAR2 (2) NOT NULL,
KAY_NAME2 VARCHAR2 (10),
PRIMARY KEY ( ID2, SUB_ID2 ) ) ;

The error occurs when I run the client and not at deploy time. Here is the client code:
public void addComment(Integer primaryKey, String comment) {
System.out.println("primaryKey------>" + primaryKey);
try {
PGEstablishmentLocalHome establishmentHome = (PGEstablishmentLocalHome) PGServiceLocator.getInstance().getLocalHome("PGEstablishmentHome_L");
PGEstablishmentLocal establishmentLocal = establishmentHome.findByPrimaryKey(primaryKey);
establishmentLocal.addComment(primaryKey,comment);
} catch (PGServiceLocatorException e) {
e.printStackTrace();
} catch (FinderException e) {
e.printStackTrace();
u haven't defined the PK entry in the Establishment EJB Bean in DDYes look in the standard DD.
What's more I need both DD as I would with most ejb containers.
The field DB_ESTABLISHMENT_ID is required and I cannot set it to NULL.
Any other help greatly appreciated.

Hi experts!
I'm trying to use a jar file located on the server on one of my WD Projects. (KM)
I've actually figured out which Software Component provides a DC with the jar i'm looking for by looking into the help site from SAP that tells me which SCs should i import to use KM projects.
But let's suppose i was using some kind of functionality not documented on Help from SAP, just like having the requirment to check the roles for a user on the portal, or something like that.
How can i detect which DC use a specified jar, and which SC contains the DC?
I'm looking for some kind of tool that can track software dependencies in a way that i can only have to tell which is the class/jar that i want to use and that tool returns me the SCs. Is there any tool available?
I've seen here on the forum a excel list that provides the relationship between jars and classes on some APIs, but the association between jars and DCs and between DCs and SCs is missing.
I think this is a basic requirment for reusing software code.
Can anybody help?
Thank youHi John,
Finally someone has something to say regarding this question. Thank you for sharing a way to accomplish my doubts on software dependencies.
I was expecting a better way to track those dependencies but for now i would look to your solution as an acceptable "workaround".
I'll not post my question as answered because i'm hoping there's another way and someone could share it, or until someone from SAP tell me this is the "official" way.
Thank you again! -
hi,
i have two tables department and employee.The employee table contains the foreign key dept_id.When i am trying to insert it doesnot insert the foreign key in the Employee table.Can anyone give an example program along with the ejb-jar.xml and sun-cmp-mappings.xml file

Deployment changes from websphere to weblogic
Hi gurus,
I am trying to deploy a sample application written for websphere V5.1 to weblogic8.1, what are the changes i need to do to the code and as well deployment descriptors.
I have lot of CMPs and a common ejb-jar.xml, ibm-ejb-jar-bnd.xmi and ibm-ejb-jar-ext.xmi. How can i convert these into weblogic's ejb-jar.xml ( i guess it is same for both), weblogic-cmp-rdbms-jar.xml and weblogic-ejb-jar.xml.
And for session beans and jsps what are the changes i need to focus...and any at code level also ?
It is highly appreciated if anyone could show some light on this...thanks in advance.
cheers,
kuruhiya,
thanks for the reply, i figured that "ibm-ejb-jar-bnd.xmi" is used for JNDI binding just like "weblogic-ejb-jar.xml" does, where as what is this xmi will do "ibm-ejb-jar-ext.xmi". Yes, am really glad am not using EJB1.1 spec of old websphere. What paremeters from the Webshpere's CMP i can provide in weblogic-cmp-rdbms-jar.xml.
thanks,
kuru

I am trying to get Container Managed Relationships working with Oracle Application Server. I am sure that the problem it quite obvious to anyone who has got this working before, but after carefully following numerous examples, I still cant get them to work. I have various issues including the application server blocking when it calls the getB() method in "A" to populate the items from table "B", even though the generated SQL looks okay e.g., "select B_PK from B where (b_fk = 1)".
I would be extremely grateful if you could point out my (hopefully obvious) mistake as I wrestled with it for the past couple of weeks.
Any ideas?
Cheers,
Jonathan
I have two tables A and B; A has a one-to-many relationship with B:
Table A:
A_PK (primary key)
A_NAME
Table B:
B_PK (primary key)
B_NAME
B_FK (foreign key to table A)

p = home.create("Violetta");
p.addNewPet("Jenny");
p = home.create("Frank");
p.addPet("Jenny");
p.addPet("Jenny");
May this be a timing problem? Or is there a command I could execute to ensure all data manipulation is populated to the DB. (Like close() in JDBC)
TIA

hi everyone. i am stuck, cheked everything and don't know where to look. i hope someone will help me. i use websphere 5.0
i have 2 cmp entity ejb with one-many relationship between them. I wrote QL query using foriegn key. when i generate EJB-RDB mapping the error appears in TASK saying " myTable o does not have a field myforeignkey". when i click on tast it opens ejb dep...descriptor. i check descriptor and foreign key is there.
where should i look? when i run validation before mapping generation it doesn't produce any error.i am new to J2ee and i let websphere to generate all description code. I spend 4 hours looking for this error and i just can'f fix it. it looks fine to me. can you have a look? i know the code is big. if you get extra time then help me. i cut it down. there is two entity beans each with one attribute. order id has second attribute as foreign key -generatorhome_id.
the full error is like this:
WQRY0036E:OrderId o does not have a field generatorhome_id. when i click on it takes me to my created <query-method> findByFor
please help if have time. the code should be straight forward. if you want me to simplify code so you can better understand then let me know.

[email protected]Hi Simon,
I'm reposting your message to the ejb group where you can get more help. This group
is monitored more for issues regarding general product usability feedback, rather
than "how to" issues.
However, I do see you've uncovered a usability issue in as much as you couldn't find
appropriate documentation or examples to help understand the problem. Moreover, you
weren't able to figure out what to do next using the ejbc compiler error messages.
I'll take a look at the problem from this point of view.
In the mean time, ejb team, can you lend a hand?

Special procurement Key in APO
How do I define in APO the special procurement key relationships between plants within the company or consignment/ subcontracting, just want to maintain the same relationship as in R/3. I know you answered about special procurement type U: stock transfer which I got it, could you please explain how I maintain the above Sp. procurement keys in APO.
Thanks Mono
Harish's reply:
As far as i know you cant maintain Spl procurement keys in APO. This is used as an indicator in the material master for CIF and for creation of Transportation lanes in APO. So if you create manually more transportation lanes in APO to other source locations it will all be considered as sources of supply unlike in R3.Hi Mono
Are you planning to run MRP in R3 and also plan in APO for the same materials. Depending on the sequence one of the runs is wasted
you normally plan selected materials in APO and the rest in R3
You can use the X0 in product master for APO relevant indicator and CIF only these materials to APO and plan it here
as for the spl procurement keys
If you have a special producrement key in R3 the Transportation lanes are created automatically with the correct source of supply or you can ensure you manually create this(and block or delete the others) so the planning will be the same as it would be in R3 -
Parent-child relation between Activities
Hello,
Is it possible to give parent child relationship between Activities within single Project? The requirement is, parent Activity to take part in overall scheduling whereas the Dates for parent Activity are determined by the child Activities attached to it.
Thank you,
HemantHi,
In PS we can map through the network activity and activity elemnents. For scheduling the projects the start date and end date of all the activity elements are included in the respective network activity. for better understanding refer the following link.

Better way of managing heirarchical groupings?
Sort of a feature request, but also a question to other users about different approaches you like to use. I've often wished for a way of grouping layers in a heirarchy that is independant of layer order, like you can do in most 3D apps (or -ahem- node based compositing systems).
The ony ways of grouping layers that I know if in AE are:
1: Pre Comping (obviously creates a single layer from multipe layers, which has limitations in certain situations)
2: Pre-Comping and collapsing gemetries (makes management easy, but still has limitations of layers being outside comp)
3: Using nulls as parents (allows you to select, control and move groups of layers, but does not facilitate easy showing/hiding or re-use)
4: Using expressions (often problematic if you are changing layer orders around a lot to accomplish a goal)
5: Creating color-coded groups for easier selection (limited number of colors, doesn't help with anything besides selection)
Each has advantages and disadvantages and accomplishes different goals. I would love to be able to create groups of layers that could easily be hidden and shown in the layer panel; selected, copied, and re-used; contain expressions and parent/child relationships; and exist within a larger composition and be dispursed among other layers outside of the group. Using Nulls as parents is the closest thing to what I would like to be able to do, but is a bit more convoluted than I think it needs to be. It seems like the ability to put groups of layers into a "folder" that you could expand or collapse would be a helpful UI feature. If you could have a list of these "folders" in the Project window, similar to the way you have a list of solids, you could duplicate and re-use them in other comps, change the layer order around, etc, and still have a cohesive group of layers to manage as a unit.
Let's say you build an animation that has 50 3D and 2D layers, several expressions, and a bunch of keyframes. Maybe you would want to use it several times in different ways within a larger piece, but need to have access to all the layers in each instance. Also, you don't want to see all of the layers in the layer panel at once--you only really care about them as a group. One technique is to parent them all to a null, use select children to select them all at once, and shy layers to hide the layers you don't want to see in the layer pallette. The downside is that if there are already parented layers within the group it becomes very tricky not to screw up the heirarchy or any expressions. You're creating the null for no other purpose than to manage a bunch of layers as a group, but it can interfere with the relationships among them if you're not careful. Also, shy layers only gives you one level of showing and hiding to work with, which can be limiting if you have loads of layers in a comp. Simply pre-comping them, and then using collapse-geometries can work in certain situations, but it limits your ability to use things like track mattes, adjustment layers, shadows, and other relationships that require layers to be in the same comp.
Hopefully that makes some kind of sense. Please share any insights you have on the tao of managing complex groups of layers so that we all may learn!ALSO: to be able to turn the layers on and off as a group would be great--very important point I forgot to mention in the previous post. If you have layers hidden and you use "select children," turning the parent layer on and off does nothing to them.

Report Custom object with product?
if I want to create a report with the fields of a custom object in relationship with the fields of the product,is possible?
Because when i cilck in Analytics there aren't Custom Object link and in Product History isn't present the Object link where i select the columns.
Also when I go to the panel of Reporting there is not a link there is not the link that reports Custom Object with Product,also in Product Opportunity there isn't a Object link.
How can I be connected for a report these 2 entity?
Regards ValeHi Vale,
Unfortunately, not every object relationship is exposed within analytics and reports, and that is the case with the relationship you are trying to report on (i.e. Custom Object and Product). Also, Custom Objects can only be reported on using real time reporting (as opposed to the historical analytics).

BOMM to Information Steward 4.2
Hi,
We are in process of moving to information steward 4.2 metadata management from Business Objects Metadata management (BOMM).
Can someone please provide following information.
1. New features available in Information Steward Metadata management module in specific when compated to Business Objects Metadata management (BOMM).
2. Level of data (granularity) crawled in Information Steward Metadata management (Audit, Universe, secmatic layers, Reports information).
3. Information on data model used to load metadata information by integrators(Which table holds what data).Hello Suresh.
No, there is not a default universe available on teh IS metadata repository. Here are some options:
1. Metadata Management Pre-Packaged Reports. Specifically, these reports are available to answer questions such as…
Which universe objects have similar names in different classes or universes?
How many reports use a universe or a particular object in a universe?
Which objects are frequently used or not used at all?
Which data flows use a particular table?
And similarly, Which tables are used by a particular data flow?
2. Deploy custom reports on top of the IS metadata repository using Information Steward Views. Here are the Views available:
Relational Model Ÿ
Universe Model
Flat File Model
Relationships
Source Target Relationships
Derived Tables within a Universe
Derived Columns within a Universe
Universe and Report Relationships
Report and Column Relationships
End-to-End Impact and Lineage
These views are based on typical usage scenarios to allow you to build custom reports to…
Find the table and scheme names of a given column
Find all the tables and columns used in a given report
Find all the databases and schemas used in a given report
Write custom impact and lineage reports.
3. You can also export any of your metadata objects from Information Steward to a standard CWM file or for universe creation.
This allows you to import that CWM XML into the SAP BusinessObjects Enterprise Designer to create a new or update an existing universe.
Note that we are also currently researching creation of a default Metadata repository universe for inclusion in a future release. Would you be interested in providing feedback on this effort?
