getting error
redshift failed to load driver class. this error may be caused by all-in-one jar packaging. please try again with the lean package
I had the same issue and the root cause ended up being because the path to the driver file consisted of a folder name that contained a space.
I had the same issue with another program. As workaround try to use com.amazon.redshift.core.jdbc4.PGJDBC4DriverImpl as driver class name. It worked for me using RedshiftJDBC4-no-awssdk-1.2.8.1005.jar
There area number of drivers for Redshift. It seems like you are using an older version. I advise you review the documentation at http://docs.aws.amazon.com/redshift/latest/mgmt/configure-jdbc-connection.html
For example, here is the latest driver version.
JDBC 4.2–compatible driver: https://s3.amazonaws.com/redshift-downloads/drivers/RedshiftJDBC42-1.2.8.1005.jar.
Yours seems to be a few point releases older

I have a project I've been working on. Recently swapped out my os drive and did a fresh install of windows. Obviously rebuilding my workflow and I encountered an error.
I try to use db migrate in the context of upgrading my new empty database with the migrations already existing from the my current project. When I try to db upgrade from my venv, nothing happens. Not an error, a message or anything. I check the db and nothing is done. Any ideas what could be causing this? I updated my keys and db logins/uri to reflect the new database still nothing.
I deleted my venv, rebuilt it and reinstalled requirements and everything worked. Hope this helps someone out there.

I am recently new here. I have a problem about Apache Wicket Framework version 1.6.0 using IDE netbeans 8.0 to Create Login Form and to connect in mysql database .I have many errors please reply on my problem
Wicket is unmanaged UI Framework. There is no way to use Wicket to connect to database.
You have to use any other mean to connect to database.
Here are some steps that might be of use:
1. Learn to access database in Java
Connect Java to a MySQL database
2. Process information obtained from Database
3. Use Apache wicket to display information obtained from database to user. In your case, IF user is authorized then redirect to other page.

I successfully integrate the postgres and eclipse but unable to test the database. I need to know where can i get help if any suggestions would be appreciate.By the way i am using java. Thanks in advance.
Selenium is not the right tool here, as it is a tool for automating testing of web front-ends. You cannot directly test your database using this tool.
You can test an application like phppgadmin, but it isn't clear that is what you want.
A better approach is just to write test cases through jUnit and jdbc, in my view. That gives you better control and testing than you can via a web front-end and it is easier to solve the question of whether you want transactions to rollback or not (selenium poses this problem since it is indirect and tests a web app that interacts with the db over a stateless connection).

I see many Grails applications using version 1.3.3. Will upgrading our Grails 2.3.11 application to use mongodb-2.0.1 cause any problems.
If you want to see what changed between versions I suggest you look at the change log for the plugin.
Typically plugins which have issue trackers (on the plugin portal page for the plugin) have some type of change log within them.

I'm currently working on an enhancement for a commercial utility that involves annotations with respect to LeadTools v13. In terms of LeadTools, it would appear that most things start off with the raster object, but without documentation for V13, it's somewhat of a challenge to make heads or tails of how to proceed in terms of reading the annotation files in.
If anyone has any code examples for such an old version, any help would be appreciated.
LEADTOOLS support don't have online documentation for this old version of LEADTOOLS. However, our help files shipped with the toolkit includes code examples for most of our functions including the annotations functions. You can find our help files in the following folder:
