How can I specify table owners when I export project to Java source?

Using TopLink Mapping Workbench, when I export project to Java source, the descriptors is automatically generated like:
descriptor.addTableName("SOME_TABLE");
Is there a way to configure the TopLink Mapping Workbench so it generates the descriptors so that the table owner is explicitly specified?
descriptor.addTableName("SCHEMA_A.SOME_TABLE");
Thanks!

You can re-name your tables in the MW to be fully qualified for the name and that's how it will be generated and used.

Export project to java source

When exporting the Toplink project to Java source from the Mapping Workbench, is there a way to tell the workbench to include the package name in the generated file? We do this manually now.
Thanks in advance

Yes, in the mapping workbench, select the project, and pick the "Defaults" tab on the right. You can specify the project there.

Convent / Make use of VB2005 project in Java

How can I convent the VB2005 project to Java
or use the project in Java just like using dll through JNative?
thanks

1 - You redesign your project for Object oriented programming, and then have at coding it.
2 - You attempt to use JNI to make those VB2005 generated dll's work, but chances are (and last time I checked), they were not a totally compatible C style interface, so have fun there.
3 - You could attempt to make things into Beans -- but then I've never seen them or most anything work reliably with VB.anything
I've converted many projects from XX to YY and I will tell you right out--option 1 has always been shortest over all and always most reliable.

My University project about java program plagiarism

I am working on my Final year Project about java program plagiarism.
i.e. My system finds similarity between two programs by "Source code" to check whether there are plagiarism.
And now i need plenty of samples and need your help.
I need two types of sample:
1. original version - a version written by your own.
2. plagiarized version - a version which is copied from original version and has modified to conceal that it is a plagiarism.(Try to treat the teacher)
My two sample programs are:
1. Find shortest path by Dijkstra's algorithm.
2. Find the determinant of a N x N matrix.
Both programs read data from txt file as input.
Now, I sincerely invite you to help me to make samples
You can choose to do the version(original or plagiarized) and the program you like.
After you have finished, please kindly send to [email protected]
If you decide to do plagiarized version, please download the following sources and modified them.

Thank you very much. Looking forwards to your program.

Ha ha, good try.
You know, if you had posted whatever you have achieved so far, you might actually have got the help you so obviously need. But now your only chance of getting any help here is to get yourself another username.
If this were true, your professors would have gladly supplied you with research material in exchange for use of your "system".

Who can introduce the development contents of the project using java ?

Hi , Web Dynpro experts:
    Could u introduce the working contents of the project using java ?
    1. Do you develop function that would run in a sap standard system(such as CRM ,internet sales)? OR develop a completely independent web application base on client's demand(EJB,JSP,HTML)?
2.Do all the user interfaces run in web browser ?
    In a word ,I just want to know what picture is it as you are using java to work on SAP ,Because I must study AP&JAVA duo to the coming project. Could you explain it for me about SAP&JAVA in any perspective according to your project experience .
   BTW: I have 2 years experience on J2EE and 1 year on ABAP. So how i should get started ?

Hi Guixin,
The most common structure for building a WebDynPro application is to expose functionality from underlying systems and present it using the WebDynPro UI. Often the underlying system is a SAP ERP/CRM type system, but can also be any WebService compliant system, or a combination of both.
Using the Netweaver System Landscape Directory (SLD), WebDynPro can send and receive data independantly of the source. SAP ERP/CRM systems will expose their functionality using RFC-enabled BAPIs. These functions can be standard SAP delivered modules or custom developed using ABAP.
The choice of where to develop your business logic really depends on the history/strengths of your organisation. If you have a strong history of ABAP development in SAP, then it would be recommended to use ABAP for your business logic and WebDynPro for UI. If J2EE is the strong suit, use that instead.
The WebDynPro interface runs in a browser (either IE or Firefox) however there is a beta version of a WebDynPro GUI for Windows which may offer some performance improvements.
HTH,
Jonathan

Please share any helpful link or tutorial or Example.
I have tried google search and tried many blogs but no luck.
[EJB 3.0 + Axis Web Services + Eclipse + Jboss ]
Regards
Prateek

Start by getting the Java EE tutorial at least v5 (it's free) and reading the sections that you are unclear about.
Basically you need to create a persistence.xml file that names a JDBC resuource. This is usually just the JNDI name of a resource that is configured on a server.
You then configure a datasource on your server that contains the actual DB connection settings and name it the same as the name in the persistence.xml.
The Java EE tutorial has sections that explain all of this.
Also, if you are starting out, I would not advise using tools to autogenerate projects/artifacts.
Doing it manually helps you understand how things work better.

Bug with exporting project to java source

Hi,
This is in TopLink 9.0.4.2 (Build 040311).
We're in the process of trying to determine if we should upgrade our TopLink from 2.5 to 9.0.4, and have not yet purchased a support contract because we haven't made the final decision yet, so I'm posting this bug here in hopes that someone can submit the bug.
In one of our projects, we have an AggregateObjectMapping (AOM) for a Measurement object that is owned by 2 different objects, each with 2 to 4 instances of this Measurement class. I set up the instances of the AOM in the workbench just fine, and looking at the XML descriptors that are written out, it appears fine. Exporting the project session XML file works fine as well. However, when it is exported to a Java file, the instances of the AOM are exported incorrectly as described below.
Here is the abbreviated mapping of the attributes of the Measurement class:
<mappings>
<mapping>
<inherited>false</inherited>
<instance-variable-name>mPrecision</instance-variable-name>
<default-field-names>
<default-field-name>direct field=yPrecision</default-field-name>
</default-field-names>
<uses-method-accessing>false</uses-method-accessing>
<read-only>false</read-only>
<mapping-class>MWDirectToFieldMapping</mapping-class>
</mapping>
<mapping>
<inherited>false</inherited>
<instance-variable-name>mQuantity</instance-variable-name>
<default-field-names>
<default-field-name>direct field=y</default-field-name>
</default-field-names>
<uses-method-accessing>false</uses-method-accessing>
<read-only>false</read-only>
<mapping-class>MWDirectToFieldMapping</mapping-class>
</mapping>
<mapping>
<inherited>false</inherited>
<instance-variable-name>mUnit</instance-variable-name>
<uses-method-accessing>false</uses-method-accessing>
<read-only>false</read-only>
<reference-descriptor>com.cimsoft.lws.units.Unit.ClassDescriptor</reference-descriptor>
<private-owned>false</private-owned>
<uses-batch-reading>false</uses-batch-reading>
<table-reference-mapping-reference-handle>
<reference-handle>
<reference-table>csrSlotGenericValue</reference-table>
<reference-name>csrSlotGenericValue_csdUnit</reference-name>
</reference-handle>
</table-reference-mapping-reference-handle>
<uses-joining>false</uses-joining>
<one-to-one-mapping-indirection-policy>
<indirection-policy>
<uses-indirection>false</uses-indirection>
</indirection-policy>
</one-to-one-mapping-indirection-policy>
<mapping-class>MWOneToOneMapping</mapping-class>
</mapping>
<mapping>
<inherited>false</inherited>
<instance-variable-name>UNDEFINED_MEASUREMENT</instance-variable-name>
<mapping-class>MWUnmappedMapping</mapping-class>
</mapping>
</mappings>
Notice that there are two direct to field mappings (mPrecision and mQuantity) and one OneToOneMapping (mUnit). The exported sessions XML file has the correct XML for instances of this object. Here is an example from a class that has 3 instances of this Measurement object mapped:
<database-mapping>
<attribute-name>mAlarmSize</attribute-name>
<read-only>false</read-only>
<reference-class>com.cimsoft.lws.units.Measurement</reference-class>
<is-null-allowed>true</is-null-allowed>

<association-value>csrStock.currentSizePrecision</association-value>
</association>
</aggregate-to-source-field-name-associations>
<type>oracle.toplink.mappings.AggregateObjectMapping</type>
</database-mapping>
<database-mapping>
<attribute-name>mLotSize</attribute-name>
<read-only>false</read-only>
<reference-class>com.cimsoft.lws.units.Measurement</reference-class>
<is-null-allowed>true</is-null-allowed>
<aggregate-to-source-field-name-associations>
<association>
<association-key>unitId</association-key>

<association-value>csrStock.lotSizePrecision</association-value>
</association>
</aggregate-to-source-field-name-associations>
<type>oracle.toplink.mappings.AggregateObjectMapping</type>
</database-mapping>
However, here are the corresponding mappings in the exported Java file (with what it really should be manually inserted by me in comments):
     AggregateObjectMapping mAlarmSizeMapping = new AggregateObjectMapping();
     mAlarmSizeMapping.setAttributeName("mAlarmSize");
     mAlarmSizeMapping.setReferenceClass(com.cimsoft.lws.units.Measurement.class);
     mAlarmSizeMapping.setIsNullAllowed(true);
     mAlarmSizeMapping.addFieldNameTranslation("csrStock.alarmSizeUnitId", "unitId");
     mAlarmSizeMapping.addFieldNameTranslation("csrStock.alarmSize", "y");
     mAlarmSizeMapping.addFieldNameTranslation("csrStock.alarmSizePrecision", "yPrecision");
     descriptor.addMapping(mAlarmSizeMapping);
     AggregateObjectMapping mCurrentSizeMapping = new AggregateObjectMapping();
     mCurrentSizeMapping.setAttributeName("mCurrentSize");
     mCurrentSizeMapping.setReferenceClass(com.cimsoft.lws.units.Measurement.class);
     mCurrentSizeMapping.setIsNullAllowed(true);
     mCurrentSizeMapping.addFieldNameTranslation("csrStock.currentSize", "alarmSize");
     mCurrentSizeMapping.addFieldNameTranslation("csrStock.currentSizeUnitId", "unitId");
     mCurrentSizeMapping.addFieldNameTranslation("csrStock.currentSizePrecision", "alarmSizePrecision");
     // should be: mCurrentSizeMapping.addFieldNameTranslation("csrStock.currentSize", "y");
     // should be: mCurrentSizeMapping.addFieldNameTranslation("csrStock.currentSizePrecision", "yPrecision");
     descriptor.addMapping(mCurrentSizeMapping);
     AggregateObjectMapping mLotSizeMapping = new AggregateObjectMapping();
     mLotSizeMapping.setAttributeName("mLotSize");
     mLotSizeMapping.setReferenceClass(com.cimsoft.lws.units.Measurement.class);
     mLotSizeMapping.setIsNullAllowed(true);
     mLotSizeMapping.addFieldNameTranslation("csrStock.lotSizeUnitId", "unitId");
     mLotSizeMapping.addFieldNameTranslation("csrStock.lotSize", "currentSize");
     mLotSizeMapping.addFieldNameTranslation("csrStock.lotSizePrecision", "currentSizePrecision");
     // should be: mLotSizeMapping.addFieldNameTranslation("csrStock.lotSize", "y");
     // should be: mLotSizeMapping.addFieldNameTranslation("csrStock.lotSizePrecision", "yPrecision");
     descriptor.addMapping(mLotSizeMapping);
It appears that the actual Measurement descriptor is being modified accidentally as it's being exported, as you'll notice that the first mapping (for mAlarmSize) correctly maps the default "y" to "alarmSize", and then the next mapping (for mCurrentSize) instead of mapping "y" to "currentSize" maps "alarmSize" to "currentSize", and the next AOM maps "currentSize" to "lotSize" instead of "y" to "lotSize".

No one ever responded, so I'm commenting to bring it up again. It turns out that the error happens not just exporting to Java, but anytime the command-line project generation is used. If the Workbench is used to export either to XML or to a Java file, the file is generated correctly. It is not generated correctly if you try to do it from the commandline (e.g. from a build environment).
This has happened with 9.0.4.2 through the current 9.0.4.5.
Here are different ways I've tried doing it from the commandline, and they all generate the erroneous XML and Java files:
java oracle.toplink.workbench.external.api.JavaSourceGenerator inputMWP outputJava.java
and
java oracle.toplink.workbench.external.api.DeploymentXMLGenerator inputMWP outputXML.xml
which are recommended by the documentation. Also recommended by the documentation:
JavaSourceGenerator.generate( inputFile, outputFile )
and
DeploymentXMLGenerator.generate( inputFile, outputFile ).
From decompiling the management workbench to see what it was doing differently:
MWProject project = WorkbenchSession.instance().openProject( inputFile );
if ( doXML )
project.setProjectDeploymentXmlDirectory( directory );
project.setProjectDeploymentXmlFileName( filename );
project.exportDeploymentXml();
else
project.setProjectSourceRootDirectory( directory );
project.setProjectClassName( classname );
project.exportJavaSource( outputFile );
//Also tried plain old project.exportJavaSource(); which appears to actually do something different.
Any ideas? It looks like a bug to me, particularly that different java or XML deployment files are generated when run from the commandline versus run from the UI. Obviously, the commandline is very important because it is what the build system needs.
Thanks,
Greg
