Alfresco Indexer plugin + Apache ManifoldCF integration issues.

ShashikanthC — Mon, 10 Feb 2020 07:12:32 GMT

I'm trying to integrate Apache ManifoldCF into Alfresco, using Alfresco Indexer plugin from here. According to the docs in the repository, here are the steps I've followed to install alfresco-indexer-plugin and integrate apache manifoldcf:

1. Cloned Apache ManifoldCF from trunk (ManifoldCF), built it using ANT, MVN.
2. Cloned alfresco-indexer repo, built project using MVN, generate alfresco-indexer-webscripts amp, installed it onto local alfresco installtion using module-management-tool.
3. Copied alfresco-indexer-client jar from alfresco-indexer to apache manifoldcf's connector-libs dir.
4. Started alfresco, started manifoldcf, created a new repository connection in manifold webapp to using 'Alfresco Webscript' module.

This is where it's going south. ManifoldCF is unable to establish connection with Alfresco.

Connection Status: Threw exception: 'Alfresco connection check failed'

ManifoldCF logs:

There are also errors in Alfresco that arised when alfresco-indexer-webscritps amp module was installed.

I don't know if I'm doing anything wrong regarding build & deployment of jars or any other. Any help on solving this issue is highly appreciated. Thank you for looking into this.

When installing the amp module, one of the jars in the local alfresco installtion was overriden by alfresco-indexer-webscripts amp, which I beleive is causing the "java.lang.NoSuchMethodError". But I'm not sure about it.

Alfresco version: Enterprise - 5.2.2 (r73ead3c7-b41)

Hi @ShashikanthC,

The Alfresco Indexer plugin is not maintained by Alfresco ("Alfresco Indexer is an unsupported, community, experimental effort") and looks like it only supports Alfresco 5.0 - it will need updating & porting to support 5.2+. Perhaps you could raise an issue on the github project?
