Error "Compute DC build order: could not load used DC"

[Former Member]

Hi!

I' m a newbie to DC-development, so please excuse the - probably silly - question, but I already went through various help.sap.com-tutorials and feel still a litte helpless.

When I create a Web Dynpro-Development Component-Project under "Local Development" -> "My Components", I get for all Used DCs the warning

"Compute DC build order: could not load used DC: sap.com/com.sap.mw.jco"

a.s.o.

If I then create a Web Dynpro-Component inside the project, I receive numerous errors s. a.

"The Import of com.sap cannot be resolved."

If I look at the projects build path, it really misses all the WD runtime libraries, JCos a. s. o.

If I try to add a "Used DC", I get - under "Local Development" - the list of DCs s. a. BI_UDI, SAP-JEE ..., but cannot expand any of these.

Could anybody tell me what I' m missing?

Thanks in advance!

Regards, Thomas

The NWDS SP15 installation forgets to copy the .dcdef files for the DCs of the SAP standard SC's. You can copy them by hand from the installation sources.

Open a command prompt go to the IDE folder of the installation sources and execute the following command:

xcopy *.dcdef "C:\Program Files\SAP\JDT\" /s

This assumes that you installed NWDS into C:\Program Files.

Alternatively you can install NWDS SP16, which does not have this, but other problems....

Pascal,

Indeed my SP 15 installation has no .dcdef files. But a search on *.dcdef in my C:\<INSTALL SOURCE>\J2EE-RUNT-CD\IDE folder and subfolders shows no .dcdef files either. ?? Despite this, SP 15 still function for me (though I had to re-synch Used DCs in a couple of cases). Can you explain why?

Windows XP? WinXP Search sucks. try searching using a command prompt and the dir command:

dir /s .dcdef

You will only face these problems when using the Local Development "SC".

Even using DOS dir command, no .dcdef files. But since that only impacts Local Development SCs, I won't worry about it. Thanks.
