Hello,
I was able to get the DIH working in SOLR 3.6.1 (placed the sqljdbc4.jar
file in the lib directory, etc). Everything worked great. Tried to get
everything working in SOLR 4 beta (on the same dev machine connecting to
same db, etc) and was unable to due to the sql driver not loading.
What i've done:
1. SOLR 4 admin comes up fine(configured solrconfig.xml and schema.xml)
2. Dropped the sqljdbc4.jar in the lib directory
3. Added sqljdbc4.jar to classpath
4. Added dataimporthandler to solrconfig.xml:
<lib dir="../../../dist/" regex="apache-solr-dataimporthandler-\d.*\.jar" />
<lib dir="../../../contrib/dataimporthandler/lib/" regex=".*\.jar" />
5. Even tried jtds which also gave me errors that the driver could not be
loaded.
Here is my datasource in the data-config.xml (DIH config file):
<dataSource name="db"
type="JdbcDataSource"
driver="com.microsoft.sqlserver.jdbc.SQLServerDriver"
url="jdbc:sqlserver://DBSERVERNAME;instanceName=INST1;user=solr;password=password;applicationName=solr-DIH;databaseName=scratch"
user="solr" password="password"/>
Here is the error i get when trying to use jdbc connector:
