Automatic installation of DAR fails

Hi all.

We are automating our deploy process, and one part of that is the DAR installation. So I found this nice document that outlines how to install DAR files by calling an ant script:

https://community.emc.com/docs/DOC-5234

But, unfortunately, after following the instructions, it looks fine at first but then fails with this error:

Has anyone seen this before, and knows what causes it/how to solve it?

a) You can find the same information in the Composer user guide.

b) What is your version stack? I have scripted the deployment of DAR files with 6.5xx. However I always used the Headless Composer which is included as part of the Content Server install. And unless needed for reference projects I always deleted the Eclipse workspace before launching headless composer.

Hi, thanks for your reply.

To verify the version stack, I moved everything to the content server instead, and there it worked.

The problem turned out to be that my classpath contained the 'normal' dfc jar files, and that was not ok. In the classpath, there should ONLY be the composer startup.jar. When I corrected that on my machine, it worked there also.

Thanks!

glad to hear its working... classpaths are a pain.... which is one of the reasons why for deployments I always do them from the content server host. that way I know Headless Composer, is correct; version and settings (dfc.properties).
