SAPJCo3

[Former Member]

I want install the SAPJCo 3. I use xp servicpak 3 and work with eclipse. My problem is that sapjco3.dll doesn´t run. I put it in windowssystem32. I read in the Forums that it works only on new windows versions. Is that true? How i can workaround this problem?

Windows XP is supported.

Every program and DLL is generated with a specific windows compiler version. The resulting programs need a runtime from that compiler version to be able to run.

If you read

Note 1077727 - SAP JCo 3.0 release and support strategy

you'll find

JCo 3.0 requires the Visual Studio 2005 C/C++ runtime libraries (8.0.50727.4053).
See SAP note 1375494 for details on how to install them.

Install those and see if it works.

Yes, it can't load it because it can't find the runtime functions provided in e. g. MSVCRT90.DLL (and others). Just read the note, it contains all information about the necessity of installin vcredist (the runtime). Forget for the moment about "loading the DLL in eclipse".

sapjco.dll depends on the installation of the runtime.

why i need the Microsoft Visual Studio? I use the JDK.

[markus_doehr2]

sigh

You don't need Visual Studio.

I try again to explain:

sapjco.dll was built/compiled by SAP using Visual Studio. Every Visual Studio/Compiler version needs a runtime environment. This runtime environment is the vcredist.msi package.

SAPJco can't be loaded because it's not an isolated DLL but depends on that runtime. If the runtime is not present it can't resolve symbols and hence it doesn't load. That's how Windows work, how it worked in the last two decades. Because it seems that you don't have this runtime installed (as mentioned by the note) you can't use sapjco.dll.

You can read the note here:

http://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes/sdn_oss_bc_op/~fo...

Just install vcredist and try again and it will work.

You can also check you windows event log, it will also have errors that assemblies are not found.

So either install the vcredist package or stop using SAP JCO 3.x because without it won't work.

Again: install the vcredist package.
