Hi,
I've written a servlet hosted in Tomcat that accesses a Xindice instance
directly from the servlet.
------------------------------------------------------------------------
---------------------------------------
The servlet's service method looks something like the following code
fragment:
...
String strXindiceDriver =
"org.apache.xindice.client.xmldb.DatabaseImpl";
Class clXindiceDBClass = Class.forName(strXindiceDriver);
dbXindiceDatabase = (Database) clXindiceDBClass.newInstance();
DatabaseManager.registerDatabase(dbXindiceDatabase);
...
this.xindiceCurrentCollection =
DatabaseManager.getCollection("xmldb:xindice://" + collectionName); ...
XPathQueryService xpqsService = (XPathQueryService)
xindiceCurrentCollection.getService("XPathQueryService", "1.0");
...
ResourceSet rsResultSet = xpqsService.query(strXpath);
...
------------------------------------------------------------------------
-------------------------------------------
My main questions:
Since the servlet container (e.g. Tomcat) is allowed to invoke a
servlet's service method on multiple threads/requests at the 'same'
time, is the code snipped threadsafe and multiuser safe?
If it is threadsafe/multiuser safe, at what 'point' does it beome so.
For instance, can I run the registration code once, and just instance a
separate collection for each user?
Thanks for any help and insight.
