Java server component library DC build fails

[Former Member]

Hello,

I have problem with building sda from Java server component library DC which contains external library DC and jars.

Btw., I implemented newest JDI patch (note 935334) so I don't have problem with packing jars into sda.

How did following steps:

<b>External library DC</b>

1. Import jars into library subfolder

2. Add all jars to public part jarAPI, which is created with 'Provides an API for developing/compiling other DCs' setting

3. Add all jars to new public part jarSDA, which is created with 'Can be packaged into other build results (e.g. SDAs)'

<b>Java server component library DC</b>

1. Add jarSDA and jarAPI to Used DCs, with <i>Build Time</i> and <i>Run Time</i> Dependency Type checked and <i>strong</i> runtime qualifier selected.

2. Add jarAPI to Entity References of defLib public part

3. Build Java server component library DC

After that build fails with following error log:

Am I doing something wrong or SAP again released something not tested?

Thank you for your answers!

Well, the solution is (which is strange) just not to add anything to Entity References of defLib public part, just both public parts from External library DC to Used DCs of Java library DC and then, in DC's where you use jars, just add defLib public part to Used DCs.

The trick is in the special "SERVERCOMPONENTS" entity that can't be editied. If it is the only entity in the public part it will automatically forward Jar files from used compilation public parts.

Did you also follow the instructions in note 891223? This note is referenced from note 935334 and describes how to update the Build plugins in your track(s).

Yes, of course. Otherwise, I would be unable to pack jars into sda. Btw., if don't add jarAPI to Entity References of defLib public part, no error is generated.
