Re: [smila-user] 3rd-party-classe in own pipelet
|
Hi there,
thanks for your quick responses. It seems that neither the "class-loading" nor the "config.ini" does trick.
@Thomas:
Yes I'm trying to integrate my pipelet and this third-party JAR in a SMILA "integration environment".
The thing is that the class-loading error occurs apparently upon checking the correctness of the pipeline (AddWebPipline) containing my pipelet (ExtractFeedPipelet) as in the following snippet
2011-01-11 16:24:40,369 INFO [Component Resolve Thread (Bundle 5) ] jmx.JmxManagementController - SMILA:C0=Processing,C1=Simple Pipelet,C2=AddWebPipeline,Agent=org.eclipse.smila.integration.imc.extractfeed.ExtractFeedPipelet@line-109
2011-01-11 16:24:40,371 ERROR [Component Resolve Thread (Bundle 5) ] bpel.ODEWorkflowProcessor - Start of BPEL workflow service aborted: Unknown fatal error.Service is non-functional, please fix problem and restart bundle
java.lang.NoClassDefFoundError: org/apache/solr/common/SolrInputDocument
at java.lang.Class.getDeclaredConstructors0(Native Method)
at java.lang.Class.privateGetDeclaredConstructors(Unknown Source)
at java.lang.Class.getConstructor0(Unknown Source)
at java.lang.Class.newInstance0(Unknown Source)
at java.lang.Class.newInstance(Unknown Source)
Isn't there a single place (just like the plugins-folder) where one can put a JAR such that the contained classes are known to SMILA upon start of SMILA.exe ???
In other words, where can I manipulate the classpath of SMILA that is provided to ALL bundles or is this not possible this way?
Thanks for your help
Best regards,
Patrick

Hi Patrick,
I think you mean the configuration/config.ini - there you find the
bundles to load and the according init-levels in the binary build.
Cheers,
Martin
