I am following this tutorial,

but i am not able to get the right username and password to import data. How do I know what the username password is? By default I see tomcat6 as database and username and no password in the textbox. As i am following the tutorial I changed it to username: postgis and password: postgres.

How do I know what my username and password is?

EDIT

Import the data in PostGIS, which requires PostGIS connection.

UPDATE

Ok so i got the user and passwd but when I am trying to add the shapefile using the Shape File to PostGIS Importer Plugin and having made connection successfully, I am getting this error when I am adding the shapefile.

Connecting: host=localhost port=5432 user=admin dbname=shpRepo password='**********'

Can somebody tell me where am I going wrong?


Question: When is lock not needed in multithreading
Answer: You will need to analyze it like peeling an onion. 

Changing the properties of objects that are stored within a List&lt;&gt; will not cause its index position to shift. It will not cause the List&lt;&gt; to perform any reallocations either. 

Therefore, If the List&lt;&gt; are not being modified (objects inserted, deleted, moved, or replaced), then:

(1) you are right in that using List&lt;&gt; that is fully pre-initialized with objects would be sufficient. 

But (2) you should then look at the next layer: does the computation of each object have any possibility of interfering with each other. Since we cannot see the code for the computation, we can't comment on that.

This analysis is only applicable to the List&lt;&gt; implementation provided in the .NET framework. If someone implements its own IList&lt;&gt;, with non-trivial logic and behaviors (such that they do not mimic the behaviors of the standard implementation at all, say, by autonomously modifying the ordering or index positions of objects) then the analysis does not apply.
