Can't answer all of your questions, but here's some...

Hi,

i am trying to access my xindice 1.1b3 database using embeded mode and get
the following exception:
There were 10 errors:

First question: which Database (driver?) to use. Shown below is the code i
use to access the database.
I use org.apache.xindice.client.xmldb.embed.DatabaseImpl, but the embeded
test uses only
org.apache.xindice.client.xmldb.DatabaseImpl (without embed). Does it matter
which database class to use?


     // loading driver
     String driver = "org.apache.xindice.client.xmldb.embed.DatabaseImpl";
     Class c = Class.forName(driver);

     // register database
     database = (Database) c.newInstance();
     DatabaseManager.registerDatabase(database);

// get collection
String db_uri = "xmldb:xindice-embed:///db/testDataStore";
col = DatabaseManager.getCollection(db_uri);


Don't know which you _should_ use, but I do:

import org.apache.xindice.client.xmldb.embed.DatabaseImpl;
DatabaseManager.registerDatabase(new DatabaseImpl());
and use xmldb:xindice-embed:///


Second question: for the embeded mode, must the xindice database be running
in a servlet container (Tomcat)?


No, it _should not_ be running as a servlet. Basic rule is: only one JVM accessing the db directly via embedded mode. If you need more than one, use the Xindice servlet, and use XMLRPC (thus, you still maintain the one JVM rule, i.e. only the servlet now).

Third question: when using the commandline tool (tomcat is not running):
xindice lc -v -l -c /db
gives the following result:

[INFO] DatabaseImpl - -Specified configuration file:
'c:\programme\xindice\\conf
ig\system.xml'
[INFO] Database - -Database points to
c:\programme\jakarta-tomcat-5\webapp\xindi
ce\web-inf\db
[INFO] Database - -Meta information initialized

       contextDataInfo_rel
       sdoData
       histData_rel
       testDataStore
       relData
       histData_sdo
       system
       contextDataInfo_sdo
       meta

Total collections: 9
[INFO] Collection - -[main] '/db/system/SysConfig' Set document database.xml
[INFO] Collection - -[main] '/db/meta/Metas/system/SysConfig' Set object
databas
e.xml


is the call with the -l option the same as using embeded mode?


Yup.

Any answers to my questions are appreciated.


Hope this helps.
