Java EE 5 on NetWeaver 7.0

Hi everyone
Please could someone clarify whether NetWeaver 7.0 can support Java EE 5?
From what I've read, I see that it supports J2EE 1.4 - but there's functionality in 1.5 that I need to use. Is there an upgrade available for NW 7.0 to support Java EE 5? If not, is one planned for the future?
One option would be to upgrade to NW 7.1, but I don't think Portal is released yet (which is a crucial part of our system).
Any ideas?
Thanks in advance!
Stuart

Thanks Andi
I've downloaded and installed CE 7.1 and about to start playing around with it now.
You say that it's not Java EE 5, but it is a certified Java EE 5 compaitible application server (see [http://java.sun.com/javaee/overview/compatibility.jsp])
Even if SAP provide their own implementation, surely it's still an implementation of the same specification? Otherwise Java EE is completely useless if you can't expect a consistent platform (which is what Java was intended to provide). Or am I missing something here?
I'm relatively new to Java, so could well be me misunderstanding something.
Thanks!

JAVA for BI with Netweaver 7.1

Hello Collegues
We have a Netweaver 7.1 Installation, and BI. Does anyone knows how to configure Integrated Planning with this new plataform (7.1). The BI Java Stack is not "available" on the instalation wizard, so de Basis Team, couldn't set up a Jave Engine.
Thanks for your Help.
Jaime Benavides

Hi,
We have a new Netweaver 7.1 Installation. We also installed BI on this Netweaver Installation. When installing BI, there was not an option for installing a BI Java Server, so Integrated Planning, does not work.
The question is How to configure Integrated Planning, (BI Java Based), on BI, when there is a Netweaver 7.1 Installation.
Best regards

Java Addin in SAP Netweaver 7.0 EHP1

Hi Experts,
I have a question about Java Add-in in release Netweaver 7.0 EHP1. As I have understood, with SAP Business Suite 7.0 cannot install java add-in in abap system. Is that correct?
I have in a upgrade proces of BW from 3.5 (ABAP, NO-UNICODE to Netweaver 7.0 EHP1 (without unicode conversion). The upgrade has successfully completed, but now I need to install portal components (EP, EP-CORE and BI-JAVA). How can I install this componentes?... If I install a new system Portal, this would have to be UNICODE... so, can I have, in the same server, two system, one NO-UNICODE (BI) and the other UNICODE (Portal)...??
Best Regards
Juan Carlos Barraza

Hi Barraza,
We had this similar issue. So, here are the answers for your questions.
- Yes, correct. As of SAP Business Suite 7.0 one cannot install java add-in in abap system (Note 855534 ).
- You have Abap as Non-unicode on EHP1. So, Java AddIn installation is NOT supported as Java is a Unicode. The only way for you is, to install a separate Java System in the same machine. Yes, you can install 2 or many systems in a server if the server is strong enough. Then connect the Java system to the Abap system, it works. There is a configuration for this connection.
Later, if you want to upgrade the Abap system to EHP4 or upwards, it can also be done without much hassel. Please award if you find my post useful.

Mohan.

How to create web service for a Java class in SAP NetWeaver Studio

hi all,
i am using SAP Netweaver Developer Studio.have created a normal java project and i want to create web service for one of the classes in this project. i used the Web Service Creation Wizard to create a web service for this class. but it says there's no methods available for VI. all my methods in this class are public, what should i do?

Hi,
I guess there are other ways. But this is an easy way, if you find the right wizards.
Besides this it is good practise to define interface methods so that session bean implement these interface methods, and thus seperate the interface from the implementation.
In this approach you will need 3 projects:
An enterprise application project (will contain EJB Module)
An EJB Module project (will contain session bean)
A Java project (contains code that implements the session bean methods)
In my previous post I suggested to use a J2EE web mudule project. This was a mistake, it should be EJB module.
But it should be possible to do it in another way. It is up to you.
Good luck, Roelof

Getting an error in Java Project in SAP NetWeaver Developer Studio

Hi,
I am getting this error in my Java Project developed in SAP NetWeaver Developer Studio.
Exception occurred during launch Reason: Source locator does not exist org.eclipse.jdt.debug.ui.javaSourceLocator
Is this problem of not defining some External .jar file or problem with Eclipse?
I am developing Java Project which connects with SAP Master Data Management.
I am referring to a PDF named "How To identify identical master data records using SAP MDM 5.5
Java APIu2019s".

This may be because of the metadata(registry) cache when it was written out by a second instance of NWDS.
So the plug-in appears in the file system but NWDS doesn't see it in the metadata
Delete the .metadata file from your workspace and then start up NWDS. It might work.

Using Java keystores with SAP Netweaver for SSL

Hi all,
I'm configuring Netweaver to use SSL and trying to reuse our client and server sertificates from the Tomcat, which are stored in java keystore files. What I've tried is to import the keystore file using the Import Keystore View function in NWA/KeyStorage GUI. I'm getting an error, when trying to do so. Is such a function supported by the Netweaver at all, so could I use standard java keystores somehow? What could I do alternatively?
regards,

I have only "NegativeArraySizeException" displayed on the top of the NWA screen without any further details. I've also tried both .jks file extension or left it blank, the same error. The only workaround I've found at the moment is to export certificates to separate files one by one from my JKS (using JDK's keytool -export command) and then import them to the ICM_SSL_<instance> keystore view (using Import Entry button). Of course, it's only a workaround, because the amount of client certificates could grow significally for the productive system. So, I'm still looking for some solution to use standard Java Keystores (JKS) in NWA/KeyStorage

hi ambi,
In the tool bar options got to 'window'-> 'open perspective ' select 'java' perspective. create a new project in the java perspective. while creating project itself you'll have the optin to elect which type. in that specify java. give the package name also. if you want to include a class, right click your project, select class. create your java class. when you save , the compilation takes place automatically. inorder to run your java class, select 'Run' in the tool bar. create a configuration file for your class . press Run.
it'll give the output in the console below.

Invoking Java Applet from SAP Netweaver Eportal using java webdynpro

Hi ,
We are using SAP Netweaver portal version 7.0.WE want to invoke java applet into webdynpro java application on button click.
The Applet should open in a new window when the particular parameter is selected and the button is clicked
The code is given below:
String html = "<HTML> <HEAD></HEAD> <BODY><APPLET code=\"org.faceless.pdf2.viewer2.PDFViewerApplet\" type=\"application/x-java-applet;version=1.4.2_05\" archive=\"bfopdf.jar\" width=800 height=600></APPLET></BODY></HTML>";
IWDCachedWebResource resource = WDWebResource.getWebResource(html.getBytes("UTF-8"), WDWebResourceType.HTML);
resource.setResourceName("HTML_inline.html");
IWDWindow window = wdComponentAPI.getWindowManager().createNonModalExternalWindow(resource.getAbsoluteURL(),"Image");
window.removeWindowFeature(WDWindowFeature.TOOL_BAR);
window.removeWindowFeature(WDWindowFeature.ADDRESS_BAR);
window.removeWindowFeature(WDWindowFeature.STATUS_BAR);
window.open();
But after clicking on button new html window is opening and the applet is not showing properly. The java console showing the error:

Please suggest how to solve this error.

Dhruba

Hi,
I'm not sure, but I believe the 'code' argument should end with '.class'. However, your implementation of displaying a Java applet seems ok, the error is within the applet's Jar file
Anyway, have a look at http://download.oracle.com/javase/1,5.0/docs/guide/plugin/developer_guide/using_tags.html#applet and http://www.w3.org/TR/html401/struct/objects.html#h-13.4 on how to use the <applet> tag
As a test, you could try and create a local HTML document on your local desktop, including the applet. I would suspect you will receive the same error in your Java console
I believe the only option is to recompile your Java applet (if possible at all) against a newer JDK (1.4 and up)

Old Java delivered with Trial Netweaver

Hi,
When installing the trial version of Netweaver (minisap), a Java version is installed as well. However, this version is usually an older version, which can be insecure to your computer. Is it possible to remove it and let Netweaver use the latest version installed elsewhere on the PC ?

as long as the versions are the same you can probably also use the SUN jdk.
You then have to configure it in the Java Server Startup Framework.

SAP NetWeaver 04s SP7 Java Version And SAP NetWeaver 04s ABAP Version

Hello,
I would like to ask if anyone has installed both Java and ABAP version on PC/Notebook.
What did you install first and why?
When installing the second of the two, did you need to turn off or detete any part of first installation?
Any advice on the installation of both versions on one PC would be appriciated.
Thank You,
Spiro.

Hi. I have installed NW04s ABAP stack and the NW04 Java stack(slim edition) on my laptop. I installed ABAP first, then the java stack. I did do it the other way around, but the ABAP stack would not load successfully, so remember ABAP first, then java. No, did not turn off or delete anything from the abap installation.

SSO to ECC (without java stack), BI (on NetWeaver), & Portal

I have a client that wants to configure their SAP systems in such a way so that the users sign onto their Windows workstations, are authenticated by Windows Active Directory and from then on they can sign on directly to an ECC ABAP instance, a BI instance, and an SAP Portal without having to supply a user/password combination again. (We already have SSO setup for users access some BI reports through the Portal, but in this case we want to setup direct access to the ECC and BI systems without necessarily going through the Portal environment).
The servers are running HP-UX, the clients Windows XP, and the AD system is running under Windows 2003.
Is this possible without using a third-party tool and if so,can anyone point me to the appropriate documentation (I've done a lot of searching, but can't find anything).
Thanks in advance!

I am sure this has been done before and often discussed here?
Take a look in the FAQ thread at the top of the forum for a general overview discussion of SSO. If you keep an eye out for the note numbers, terms used and those folks who contributed to it when searching, then I am sure will find plenty of infos to start with.
Specific vendor evaluation details and comparisons (outside of the technical realm) are generally not provided, as the 3rd parties are generally competitors...

Adding BI Java on NetWeaver Portal 2004s installation

Hi All,
We have NetWeaver Portal 2004s sps 10 installed.
We would like to know if we can add BI Java on the same instance.
Thanx
Jayant

Hi Yayant,
Yes, its possible to have BI Java stack added to Netweaver 2004s,
but from my point of view the version should already been installed with Netweaver 2004s Java stack as SAP_BW.
Check this in the System --> Status --> SAP System Data menu of your respective system.
Assign points if it helps you.

Netweaver Data base instances for Java and ABAP

Hello Experts,
Please help me to understand how the two technology stacks of SAP WAS (Java and ABAP) are configured to use underline data base in Netweaver.
Is it manadatory to have two separate data base schemas, one for ABAP applications and other for Java applications in the Netweaver?
If yes..the any idea about what are those schema differences??
- Rajan

Hello Krishna,
Thanks for the reply.
Is there any way I can access these shemas? Are they the same by structure or there are major differences?
My requirement is to build a common schema out of these two and have the data from these two schemas to be consolidated in the new schema.
Any help will be greatly appreciated.
