Subject [jira] [Created] (CONNECTORS-1281) Bug for crawling documents from Microsoft SQL database
Date Wed, 24 Feb 2016 18:26:18 GMT
Olivier Tavard created CONNECTORS-1281:

             Summary: Bug for crawling documents from Microsoft SQL database 
                 Key: CONNECTORS-1281
             Project: ManifoldCF
          Issue Type: Bug
          Components: JDBC connector
    Affects Versions: ManifoldCF 2.3, ManifoldCF 2.2
            Reporter: Olivier Tavard


I have some issue to crawl documents from a Microsoft SQL database.
The jtds-1.2.4.jar is well present in my MCF installation (MCF built from sources and jtds.jar
added in lib-proprietary from the ant script)
After crawling about 200 documents the job does not do anything and the following error is
present for each document crawled :
FATAL 2016-02-24 18:27:47,078 (Startup thread) - Error tossed: null
        at net.sourceforge.jtds.jdbc.ConnectionJDBC2.isValid(
        at org.apache.manifoldcf.core.jdbcpool.ConnectionPool.getConnection(
        at org.apache.manifoldcf.jdbc.JDBCConnectionFactory.getConnection(
        at org.apache.manifoldcf.jdbc.JDBCConnection$

It seems that there is an issue with the validation of the connection between MCF and JTDS
What is the best way to fix it ? Do we need to implement our own isValid() method and  do
a simple select into it ?

By the way, we do not have this issue with MCF 2.0.1.
