datasource

I am trying to configure a PostgreSQL datasource in Wildfly 10 Application Server on Mac OS. I am doing what the instructions prescribe. I have created an order: /wildfly-10.1.0.Final/modules/system/layers/base/org/postgresql/main. In this order I have put the JDBC driver: postgresql-9.3-1104.jdbc4.jar and I have created a module.xml file: <?xml version="1.0" encoding="UTF-8"?> <module xmlns="urn:jboss:module:1.3" name="org.postgresql“> <resources> <resource-root path="postgresql-9.3-1104.jdbc4.jar"/> </resources> <dependencies> <module name="javax.api"/> <module name="javax.transaction.api"/>

This question has been partly answered here but there is still an issue with referencing the default datasource dynamically. I'm working on an internal application that allows developers to modify configuration settings for one of our multi-tenant applications and push those settings from dev to testing, staging and production. Each one of these will have their own datasource, and the Grails app will be installed on each developer's computer. The local datasource will be the default one, and then dataSource_testing, dataSource_staging and so on will reference the appropriate environments. I

for some test I need to run a data driven test with a configuration that is generated (via reflection) in the ClassInitialize method (by using reflection). I tried out everything, but I just can not get the data source properly set up. The test takes a list of classes in a csv file (one line per class) and then will test that the mappings to the database work out well (i.e. try to get one item from the database for every entity, which will throw an exception when the table structure does not match). The testmethod is: [DataSource( "Microsoft.VisualStudio.TestTools.DataSource.CSV", "

Could somebody tell me why I'm getting blank rows after running this code? ... dataGridView.AutoGenerateColumns = false; //must be false, else getting additional columns from SQL dataGridView.DataSource = dataSet.Tables[0].DefaultView; Also tried dataGridView.Update(); but not working.
