SAP JCO Native libraries for ARM Architecture..

Hello All,
I would like to know if SAP has released any JCO native libraries for Linux ARM architecture.
We have Linux x86 libraries but do not have the source code to compile it on ARM.
Can someone help me in getting the source code for the native libraries for Linux or if there is any ARM libraries already provided by SAP.
Please help !
Best regards
Sandy

Hi,
I have the same problem - have you had any success with this. In the porting docs, sun says they can supply the source code under special agreement. Do you know anything about this?
Thanks,
Allon

ADSSAP native libraries missing - NW2004s SP12 installation on HP-UX ...

Hi Experts,
We have installed NW2004s SP 12 server on HP-UX, then after we have configured ADS as per the installation manual. Unfortunately OS Native libraries are missing in the following path ...
/sr/sap/EPL/JC03/j2ee/os_libs/
I'm not sure whether HP-UX is a supporting environment for running ADS?
If yes, how should i get those compatible native libraries for my installation.
Due to above reason we couldnt able to run Interactive forms.
Please leave your advice on this.
Thanks
MMK

Hi Swathi,
HP-UX IA64 is a non-supporting platform for ADS, so installed ADS on supporting environment and then configured.
Thanks

Using native libraries in web application (weblogic on linux)

I have a problem with loading native libraries for use with my web application. Where do I have to put them in order for the server to see them? The same app on windows runs perfectly fine, because it has no problems finding the dll files.
 So far I have tried modifying the weblogic startup scripts, to include the library in LD_LIBRARY_PATH environment variable. I've also tried modifying the security policy just in case, but I don't think it's the case, because like I said, the app ran fine on windows without messing with the policies. So, any ideas, how I could load the libraries?
 The system is a WebLogic 8.1SP4 installed on Linux i386 using JRockit JVM, the native library in question is JAI 1.1.3-alpha native acceleration library.
 PS. if it's in the wrong group, please direct me to the correct one.

Fukiku,
 Did you get this working?
 You can also try setting the environment variable java.library.path.
 Please post your stack trace to the forum as well.

Hi.
We only support Solaris on Sparc platforms, so there are no intel libs for Solaris 8.

The struggle of creating a Custom ClassLoader for Native libraries

Hello Everyone,
I'm having a really hard time writing and using my own ClassLoader in a Java Applet.
Context :
As the this link shows - http://codethesis.com/tutorial.php?id=1 - loading and especially unloading native libraries through Java requires defining our own ClassLoader, and use it to instantiate a class loading a library. When the class using native libraries has finished execution, setting all references to the classloader and calling the garbage collector will cause the native library to be unloaded. The class to load within the custom classloader is thus read byte after byte from the jar and defined using the Classloader.defineClass(..) function. So that's what I did. But I've got two problems.
Problem 1 :
On one single machine over 15 tested, the magic number of a given class read from the Jar using Applet.class.getResourceAsStream(classname) takes a value different from CAFEBABE and the defineClass function then throws an "Incompatible magic value" exception (see below). The workaround I found is to force the first 4 bytes of the byte array read from the class with CAFEBABE. But I still would like to understand why it takes a different value on this machine.
Exception in thread "thread applet-MyApplet.class-1" java.lang.ClassFormatError: Incompatible magic value 409165630 in class file Reader
at java.lang.ClassLoader.defineClass1(Native Method)
at java.lang.ClassLoader.defineClass(Unknown Source)
at NativeClassLoader.findClass(Unknown Source)
Problem 2 :
On windows, the NativeClassLoader works perfectly, but on Linux, I'm getting a java.lang.VerifyError (see below).
Code is compiled with java 1.6.0_06 on windows XP. I tried to remove everything related to native code (remove .so load), the same error is raised.
java.lang.VerifyError: (class: Reader, method: <clinit> signature: ()V) Illegal instruction found at offset 1

RFC calls with SAP JCO and IBM resource adapter for SAP - basic tuning

Hi experts,
we are working on a java portal connected to a backend system SAP by calling RFCs.
On our first integration tests, it appears to be quite slow fetching data from SAP by calling the remote functions from the custom portal. We are using SAP JCo 3.0.6 and IBM resource adapter for SAP 7.0.0.3 to integrate SAP with our portal.
Is there any basic tuning to achieve to improve performances or any hint of where to tune in SAP ?
Any help would be greatly appreciated.
Thanks a lot,
Jamal

Hi Jamal,
I understand you have already checked performance issues in the SAP Server. We had some problems with certain RFC calls and it turned out to be a badly developed ABAP sentence.
I'd recommend you to use httpwatch or another tool to check the response times from the browser, so you can point accurately where the is.

SAP Open Hub Vs SAP JCO for Extraction

Hi,
I would like to clarify for SAP JCO connectivity from some third party tool to SAP BW Server in compare to open hub:
We want to connect our internal third party tool to SAP BW/BI server by using Java technology through SAP defined JCO. Later we will create RFC and BAPIs at SAP BW server for data extraction. Those defined BAPIs and RFCs we would call from my java programs.
In such kind of scenario we can extract metadata as well as data for all defined data targets (InfoCube/ODS/DSO/InfoObject) and also can make otherdata load scheduling program to extract data and store it at my non-SAP application.
As per my understanding since we are using SAP provided JCO so there won't be any issue of license for the same. And Open hub require license if it is used to extract and send data from data targets to third party tools.
Can someone confirm for license out of above mentioned cases when exactly it would be required. Mainly I would like to know if we doun't use SAP provided JCO for connectivity and data exttraction then license woould be required or not?
You speedy response would be highly appreciatted.
Regards,
Vivek

Correct location for SAP JCO libs

Hi
I'm using IDM 7.0, and I am configuring the SAP ActiveSync adapter, which requires the SAP JCO jar and .so libraries. I'm on a solaris box, and I am using SAP JCO 2.1.8 (there is a more up to date version but it doesnt seem to work with IDM 7)
I've copied sapjco.jar to <idm>/WEB-INF/lib
I've copied librfccm.so and libsapjcorfc.so to /opt/SUNWappserver/appserver/lib
If I don't have them in this location I get very obvious error messages telling me that they are missing (when I do a 'Test Connection' from the Resources tab).
However even with the libraries here, I still get this (very similar error):
SAP HR ActiveSync: Could not initialize the SAP jCO. Please reinstall and check that the needed libraries (librfc32 and sapjcorfc) are available to Java and restart this application. ==> java.lang.NoClassDefFoundError: \n
I was wondering if anyone with a working installation of the SAP ActiveSync adapter could tell me the definitive place to put these libraries. I would rather not place copies of the files all over the place.
Thanks

I was right all along
.so libs go in /opt/SUNWappserver/appserver/lib
jar files in WEB-INF/lib.
Was using the linux version instead of the solaris ones - schoolboy error on my part.

Parent class loaders are not searched for native libraries?

I'm loading a native library in the default system classloader. I think create several new children of the default class loader and instantiate some new objects in those child classloaders. The problem is that those new objects get a LinkUnsatisfiedError when they try to call the native methods.
I was under the impression that ClassLoaders would delegate native method class to their parent class loader, the same way that they do when searching for class definition. This is confirmed by this quote from http://java.sun.com/docs/books/jni/html/design.html:
"Because each class loader maintains a set of native libraries, the programmer may use a single library to store all the native methods needed by any number of classes as long as those classes have the same defining loader."
I'm in a serious catch-22 here, because I cannot load the native library in the child classloaders (native libs are not allowed to be loaded by multiple class loaders), and I need to put the objects in a separate classloader. What is the solution?

i.getClass().getResourceAsStream("/hello.txt"); //this should be disallowedWhy is getting a resource so bad? It puts a dependency on a module, but in a plugin system, dependencies should be supported. Netbeans platform supports this same thing. I use image resources from some core modules at my own risk. If you really want to block it, override the getResource method of URLClassLoader to block unwanted resource fetching. You will have to use the SecurityManager, AccessController, ProtectionDomain, and AccessControlContext and I'm not going to tell you how ;)
i.getClass().newInstance(); //something even worseNot possible to block without package private constructors or similar restrictions as above.

Windows 8.1 ADK Error with CopyPE for the ARM architecture

Hi folks,
I am following the command line page for COPYPE ( https://technet.microsoft.com/en-us/library/hh825071.aspx )
If I read this correctly, I should use the following command :
copype arm C:\winpe_arm
The Copype.cmd file has nothing in it that accounts for ARM.
Furthermore, the Windows Preinstallation Environment Folder only has subfolders for amd64 and x86.
Where exactly is the ARM support ?
Thanks

Hi,
Based on my test, this phenomenon should be caused by lack of ARM directory in Windows Preinstallation Environment directory.

Native libraries in ABAP runtime

Hello
I have a question. Im developing application which is doing lots of XML processing (quite complicated and time consuming). Since XML support in ABAP itself its very poor we decided to use Java libraries on external server. Comunication between java and abap is done via Jco. But ... the best solution could be if we could use native libraries (java or C JNI wrapper to java) in ABAP. Is there a method or approach to expose interface in ABAP OO and then code implementation to use native library. How to deploy such library in R3.
I saw that all classes from iXML are connected somehow to native runtime.
Does anybody know how to do that, or just can point me to any documentation or example ?
Best regards
Marcin

Can you make sure this native library is in the PATH(Windows) or LD_LIBRARY_PATH
(UNIX)?
