Sybase Unwired Platform 1.5.2 - gives JCO errors

[Former Member]

Hello,

On our 64bit server we've installed SUP 1.5.2 (trial).

I have followed following blog([http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/20874] [original link is broken]😉 to learn the basics of SUP-development.

In the Unwired workspace I can test the connection to a SAP system and I can do everything described in the blog. But when i deploy the application and run it in a blackberry simulator i get errors/exceptions:

- java.lang.NoClassDefFoundError: Could not initialize class com.sap.mw.jco.JCO

- java.lang.ExceptionInInitializerError:JCO.classInitialize(): Could not load middleware layer com.sap.mw.jco.rfc.MiddlewareRFC'

JCO.nativeInit(): Could not initialize dynamic link library sapjcorfc G:SybaseUnwiredPlatformServersUnwiredServerlibsapjcorfc.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform. java.library.path C:SybaseUnwiredPlatformServersUnwiredServerin..lib;G:SybaseUnwiredPlatformServersSQLAnywhere11BIN64

First we've used the sapjco-ntintel-2.1.9 but when i've seen the 64bit error i've replaced the jco on all places described in the blog by this one sapjco-ntamd64-2.1.9. But now i am still getting the NoClassDefFoundError when testing the application...

Does anyone have a clue how we can get this to work?

Thanks in advance!

Kind Regards,

Robin

Here is the document that will help everyone fix SUP connection to SAP for Windows 7/Vista OS.

Hi,

Please make sure the dll and jar files extracted from the zip fles have been copied to the right locations.

Note : you should also update your version to 1.5.3 or 1.5.5 here -> http://downloads.sybase.com/swd/summary.do

Hi Pierre,

Thanks for your answer.

I've placed the jar and dll files on the places described in your blog:

So in librfc32.dll and sapjcorfc.dll into:

1) C:\windows\system32

2) sup install root\Servers\UnwiredServer\lib

3) sup install root\JDK1.6.0_16\bin (here we have 2 JDK1.6.0_16 folders (one normal and one 64 bit) so i placed the files in the both folders

and sapjco.jar into :

1) SUP Installationroot\Unwired_workspace\Eclipse\sybase_workspace\mobile\eclipse\plugins\com.sybase.uep.com.sap.mw.jco_1.5.version\lib

2) SUP Installationroot\Servers\UnwiredServer\lib\3rdparty

Can this be a problem with the jco in 32- or 64-bit? Or is this SUP version 1.5.2 specific? in the installation documents they also refer to jco 1.2.8 but this one isn't supported by SAP anymore...

Thanks in advance.

Robin

I don't know if the problem comes from the jco version as I've always used the 32-bit version.

Have you installed the SAP GUI on the server after the SUP installation? If it's the case, make sure the jar and/or dll files have not been overwritten during the setup (check the creation/modification date).

Hi Pierre,

It's solved, the 64bit jco and restart did the trick...

I'll give you some points for your feedback thanks.

Kind regards,

Robin

Hi Robin,

We are experiencing exactly the same problem you had (64-bit JCO). Kindly elaborate how exactly you solved the problem.

We placed the 64-bit DLLs & JCO in the directories outlined in Pierre's blog but still experience the JCO error.

Awaiting your response.

Hi Michael,

We didn't do anything else then described in the blog of Pierre.

Maybe a restart can do the trick?

Hi Robin,

We are trying to configure JCO 2.1.10 64 bit into SUP 2.0 in windows 7 64bit machine.

When we are trying to connect with SAP it generate an error like " C:\Windows\System32\sapjcorfc.dll: Can't load IA 64-bit .dll on a IA 32-bit platform "

We placed all Files in proper Directory location as you already posted in this Thread and we restart SUP as well as System more than 3 times

We couldn't understand this error because we are using JCO 64bit and Windows7 64 bit.

Please help me,

Regards,
