Exclude dependent jar from osgi bundle through maven setting in talend 6

Anonymous — Thu, 14 Dec 2017 07:18:55 GMT

I have two jobs with sap component connection and sap input when I am exporting as osgi bundle and putting it in karaf container its giving error with sapjco.dll already loaded in another classloader. java.library.path .

I checked the bundles and found that both bundle contains sapjco.jar which is tring load sapjco.dll two times in a container and failing.

I removed sapjco.jar manually from both bundle and placed jar in karaf/lib folder and it was started working

we have some automated setup through cmdline for building jobs so i can not do manual removal work

I found in project settings we can configure to exclude jar from build but its not happening

Re: Exclude dependent jar from osgi bundle through maven setting in talend 6

Anonymous — Sun, 17 Dec 2017 15:37:20 GMT

Wasted whole weekend to figure out how i can exclude jar from classpath through modifying projectsetting-->build-->osgi .maven pom settings

Now i have a feeling its not using this settings at all.

Also i tried updating pom.xml by adding dependency scope to provided by going workspace-->projectname-->pom.xml and tring to make build through studio again this pom.xml file reverting back to original pom.xml

Couldn't find anything on help documentation

Is any one has any info or link. I am tired with this

Hi Sabrina,

Thanks for reply !

My main is goal is to remove jar from class path of bundle and place that jar in karaf/lib so that it can be share by two bundle and i can avoid class loader error ( I have two different bundles with same jar dependency class loader gives error sapjco3.dll already loaded in another classloader)

I am not aware of how I can remove it from class path.Could you please provide details of that.

Thanks
Ashish
