Hi
How to develop a java project in NWDS
Thanks
Hazrath

After creating the DC,
U can see the java perspective with the dc which u have created.
In tht, u need to created proj and class names by using src/packag
right click src/packag->new->proj,class etc...
U can get this package at the bottom of JavaDc explorer..

The JDeveloper can't normally debug the java project

SOS!!!
OS: XP SP2 PRO
JDeveloper version:10.1.2
JDK version:j2sdk1.4.2_06
Before the System repairing,it works well.but after I do the System repairing action, it can't work well. but if I copy the whole directory in which the JDeveloper was installed the debug function is work well. And if I disconnect the local networkconnection, it can work well. And even the simple program "Hello world" can't debug
The following is the start time log:

Any one in the JDEV Team can give any advice? Thanks very much for previous.

there are specific instructions in the release notes for setting up and using the jdbc oci driver.
oci drivers require a matching oracle client be installed also.

Regarding the OSB Project WSDL Response

Hi i have developed a service in eclipse with XQuery , while testing this service in soap ui i am not getting the WSDL response .can u plase any one help me on this it's very urgent...................

Does your operation have response tag ?
Check your WSDL file that you used to create OSB service, to see whether the operation that you have used is having request and response tags and messages configured to it.
Otherwise you can share your WSDL file here.

Java Project as DC

Hi everyone,
I am trying to create a Java project as a DC that can be imported as a model in Web Dynpro. When I am experimenting by using local java project, I can import it with no problem into Web Dynpro as a model. But, when I am creating Java project as DC, I cannot export it to create JAR file and thus cannot be imported as model. Please help...
Thanks,
Johannes

Hi Johannes,
You objective is to import the content of the Java project as a "Model" in a WD project. Out of the currently available options in WD, Java Bean is the only suitable one here. Now, to make it available as "Model" in WD, you need to make the "JavaBean model implementation" of the Java DC available to be published through the "Public Part" of your Java DC project. Once you publish the JavaBean Model implementation classes, the content of your DC based Java project become available to be used as Model inside the WD project.
Now, coming to your question, you are not actually importing the whole source code of your Java DC project. Rather, you are only importing the "JavaBean model implementation" classes. These acts like "proxy" classes and enables your WD project to communicate with the Java project.
Hope, this clarify your doubts to some extent. Please let me know if not.

Mapping Workbench Java Project Export Exception

Hello,
We're using TopLink Workbench 9.0.4.1 build 040128
We are experiencing exceptions when we try to export our Mapping Workbench Project as a java project file. (We have never had this problem before).
I fear we may have somehow corrupted the TopLink mapping project file(s) when we were last editing them. We can open the project file and all mappings and tables look clean. However, when we try to export the java project file we get an exception (see the stack trace below).
Is there any way to recover our project file? We had made a lot of changes before noticing the problem with the java project generation. It would be a lot of work to go back to our last good back-up copy and apply the updates all over again.
Here's the stack trace from the Workbench when trying to export the java project file:

Are there many aggregate mappings in your project? Or do you know of any aggregate mappings or mappings in aggregate descriptors that have changed since you last exported your java source successfully. It appears that something in an aggregate mapping has become corrupted and I'm just wondering if you can narrow down where the problem might have occured. If this is possible, then try remapping those aggregate mappings and then generating the java source again.
If it is not possible or this does not solve the problem, you will need to send this project and the class files in to support.
Thanks,

NetBeans - Cannot create new Java project

Hello all,
I've been trying to create new Java projects in NetBeans 6 for about a week now and it just won't work. First, I receive a nullPointerException when I start the software. Then, I come to my home screen, head to File ->New Project. I'm able to specify the Java Project type. When I want to specfiy the Name and Location of the file, I get "Project Folder exists and is not empty", but the folder never existed at all. It's as if the prompt creates the folder then verifies the folder exists and repeats that error message over and over; even if I change the file name. I've reinstalled the software and the JDK many times but, I' still can't seem to get working.
Any help would be appreciated.
Thanks
-Pengu

Delete your old downloads of your JDK and NetBeans, then Download a new copy of the JDK and NetBeans, uninstall what you have go and delete all of the folders that were involved in the original install and then reboot.
Once you have done this, then reinstall from your freshly downloaded copies.
Windows does not yield it's ruined programs very easily--you just have to remove every last bit of it and start again. If the above does not work, then it may be time to go int and edit the registry to remove all reference to the JDK and NetBeans.

Can't importing a Flex project within a Java project

Hello,
I am taking over an existing project from a vendor that is no longer involved that has a two Flex projects inside of the Java project. I am using the Flash Builder plugin inside Eclipse. I have checked out the Java project locally and brought it into Eclipse and it builds perfectly. My issue is in getting Flash Builder to recognize or import the two Flex projects within. I have tried various methods of adding or importing the Flex project into my workspace but they all break the file structure in one way or another and thus make it impossible to compile in the structure that was set up. It looks like Flex was set up to build into the webapp/flash/projectname/build folder. No matter what I do Flash Builder creates other output folders or project folders. I have tried add project type, import and new. The original .project and .actionScriptProperties files are there but Flash builder seems to ignore them and create new ones elsewhere.
The file structure looks like this:
javaproject
     src
          main
               Flex
                    flexprojectone
                    flexprojecttwo
               java
               resources
               webapp
                    flash
                         flexprojectone
                              build
                         flexprojecttwo
                              build
                    internal
                    lib
                    themes
                    WEB-INF
Thank you

I am having same trouble. Installed JDK 5.0 Update 5. Installed the Studio. Ctrl+Shift+N, the only option I have is Web Application with Existing Ant Script.. Please advise how to solve this problem. thx

Eclipse Plugin: Sequence Diagram from Java Project

Any Free Plugin available for eclipse to generate sequence diagrams from the java project?
Like MaintainJ does?

If its any consolidation I have used UML a plugin for NetBeans, not Eclipse to generate such diagrams in a previous project. Would I recommend it is the next question =p.
If it's anything like ''Together' then the resulting sequence diagrams are just about useless since they will contain far far far too much detail. Sequence diagrams, Class diagrams, State diagrams etc should summarise a system and not be just an alternate detailed view of code.This.
I used to work with the guys that wrote Together and that is exactly what the UML diagrams were: an alternate view of the code. As in, they defined a language that described source code and the diagrams, and either could be used to generate this intermediate code, and either could be generated from this intermediate code. Quite neat, but as you point out, not necessarily all that useful
OP, if you're thinking of using this to "cheat" on some homework, don't bother, your tutor will spot it a mile off!

What are the BW Projects

Hii All ,
I wanted to ask you one question regarding the BW projects.what is a complete BW Project?Can I have one example for BW Project and documenetation for it.so that i could get a clear picture for it .
Awaiting your Reply ,
Thanks & Regards ,

Hi,
I will describe the life cycle of an Implementation project.
*Start with Reports*. What the client is using. What he is expecting.
If he got existing reports map the fields with Business Content BW Fields. Go to Business content and make a list of queries which are delivered from SAP. Explain them the KPI's. This should be good to start with. Also check the Tcodes they use.
Look for DataSources that get data from theses Tcode's.
*Project Preparation* (Initial stuff -- Do a conceptual review after this phase requirements gathering)
Collect requirement thru interviews with Business teams /Core users / Information Leaders.
Study & analyze KPI's (key figures) of Business process.
Identify the measurement criteria's (Characteristics).
Understand the Drill down requirements if any.
Understand the Business process data flow if any.
Identify the needs for data staging layers in BW (i. e need for ODS if any)
Understand the system landscape.
Prepare Final Requirements Documents in the form of Functional Specifications containing:
Report Owners, Data flow, KPI's, measurement criteria's, Report format along with drilldown requirements.
*Business Blue print* (Functional spec-- Do a design review after this phase)
Check Business content against the requirements
Check for appropriate
Info Objects - Key figures & Characters
Check for Info cubes / ODS
Check for data sources & identify fields in source system
Identify Master data document all the information in a file follow standard templates
Prepare final solution
Identify differences (Gaps) between Business Content & Functional specification.
Propose new solutions/Developments & changes if required at different levels such as Info Objects, Info cube, Data source etc. Document the gaps & respective solutions proposed follow standard templates
Design & Documentation
Design the ERD & MDM diagrams for each cube & related objects
Design the primary keys/data fields for intermediate Storage in ODS
Design the Data flow charts right from data source up to Cube.
Consider the performance parameters while designing data models
Prepare High level / Low level design documents for each data model. --- Follow standard templates
Identify the Roles & Authorizations required and Document it follow standard templates
Final review of design with core BW users.
Sign off the BBP documents
Realization ( Develop; Do a configuration review after this phase)
Check & Apply Latest Patches/Packages ...in BW & R/3 systems.
Activate/Build & enhance the cubes/ODS as per data model designs...maintain the version documents.
Identify & activate Info objects / Master data info sources / attributes, prepare update rules
Assign data sources .prepare transfer rules, prepare multi providers. Prepare Info packages.
Perform the unit testing for data loads.both for master data & transaction data.
Develop & test the end user queries.
Design the process chains, schedule & test
Create authorizations / Roles assign to users..And test
Apply necessary patches & Notes if any freeze & release the final objects to quality systems
perform quality tests.
Re design if required. (Document changes, maintain versions)
Final Preparation ( QA and Other final stuff before moving to production, Do a performance Review after this phase)
Prepare the final check list of objects to be released .identify the dependencies & sequence of release perform Go Live checks as recommended by SAP in production system
Keep up to date Patch Levels in Production system
Test for production scenarios in a pre-production system which is a replica of production system.
Do not encourage the changes at this stage.
Freeze the objects.
Go Live and support ( to production and support)
Keep up to date Patch Levels
Release the objects to production system
Run the set ups in R/3 source system & Initialize Loads in BW
Schedule Batch jobs in R/3 system (Delta loads)
Schedule the process chains in BW.
Performance tuning on going activity
Enhancements - if any

Cannot add Spring nature to standard Java project

Is there a way to add a Spring nature (and libraries) to a standard Java project? I would like to use dependency injection in projects other than dynamic web projects.

Yes, but the support is not in the current release (3.2 / 3.2.1). The next release scheduled for the month of December 06 will support Spring nature in a standard Java project.
For now, try the following workaround:
In the Java project, add a dummy WEB-INF/web.xml
Enable AppXRay and then add Spring Facet

Integrate into Java project without installing runtime

Hi,
in JavaFX 1.x I was able to launch my applications out of a pure Java project just by adding myapp.jar and the JavaFX runtime JARs to the Java project. So installing the runtime itself was not necessary.
Is this possible with JavaFX 2.0 too? I tried to add the jfxrt.jar to a Java project - but without any success.
The reason why I want to do this is, that users of the Java application won't be happy about an additional installation process for the JavaFX runtime...
thanks!

Unfortunately at the moment they will have to install it. There was a fairly heated conversation on this a while back:
Re: Why can't we redistribute the runtime!!!! You said we could before!
As you can see from the forum there is some licencing still to sort out for this.
Using webstart it is relatively easy to trigger the JFX install but, yea, it's still quite annoying.
Java8 will have it all included which will make life easier (a bit of an unfortunate strategy not to do this straight up, but I don't think the JFX guys had much say in that one).

Cant specify the Java Build Path in the Web Module Project

hi,
I have a problem while specify the project dependencies in the Web Module Project.While opening the properties of the web module project i cant choose the Java Build Path.The only two options i have are design root path and web service consistency check builder.Does anybody know why its like that?do i hav to reinstall the SAP developer studio?
With regards,
Jaisamma Varghese

Hi Jaisamma,
I just tested this, and for me it works as expected, within all explorer/navigator views.
Before reinstalling NWDS, check if the project itself may have some problem. Just create a new clean web module project and right-click on the project and try to access the BuildPath properties now. If it works, try to set up your project content again within this new project. Otherwise reinstalling NWDS may help.
Hope it helps

Calling dll in Java using The JACOB Project

Hi I'm trying to import and read the class and methods from a DotNet API (dll) in java code usind the Jacon Project does anybody know how to do it? (like and example or simple staps to have an idea)
thanks
Luca

afaik you cannot call windows API functions directly, you have to create a 'wrapper' method in C++ in order to access the API functions.
it will look something like
// Java code:
package a.b;
class Thingie {
public native int doThatFunkyThingie();
// c++ code
jint Java_a_b_Thingie_doThatFunkyThingie(JNIEnv *env, JObject j) {
// c++ function calls go here
}I haven't done JNI in over a year, so this is probably not entirely correct.
I recommend you read the JNI tutorial.
