datasource

Im new using this front end framework application... I recently started to work with smartgwt and i'm bulding a new application with a Spring MVC integration. I'm using a ListGrid with a RestDataSource (Consume the Rest service with mvc:annotation-driven for plain JSON) I can see that the servaice gets consuming properly perhaps my grid is never shown with the data in it. Can someone help me here ? Here's my ListGrid class public class ListGrid extends com.smartgwt.client.widgets.grid.ListGrid { private final SpringJSONDataSource springJSONDataSource; public ListGrid(List<DataSourceField>

I'd like to come up with the best approach for re-connecting to MS SQL Server when connection from JBoss AS 5 to DB is lost temporarily. For Oracle, I found this SO question: "Is there any way to have the JBoss connection pool reconnect to Oracle when connections go bad?" which says it uses an Oracle specific ping routine and utilizes the valid-connection-checker-class-name property described in JBoss' Configuring Datasources Wiki . What I'd like to avoid is to have another SQL run every time a connection is pulled from the pool which is what the other property check-valid-connection-sql

I have to use a default Role so that after the datasource has been defined and connected that role will allow me to use select statements. I know its little weird but I have to do it due to security concerns. So here is the code in my Spring's applicationContext.xml: <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="com.ibm.db2.jcc.DB2Driver" /> <property name="url" value="jdbc:db2://host_name:Port/DB_NAME:INFORMIXSERVER=SERVER_NAME;DELIMIDENT=y;" /> <property name="username" value="user" /> <property name=

I have defined two datasources in *-ds.xml on jboss 4.2.3 (redhat 4.3) Both datasources are identical. Only jndi-name differ Each defines min=max=10 <xa-datasource> <jndi-name>com.trax.hibernate.DataSource</jndi-name> <track-connection-by-tx>true</track-connection-by-tx> <isSameRM-override-value>false</isSameRM-override-value> <xa-datasource-class>oracle.jdbc.xa.client.OracleXADataSource</xa-datasource-class> <xa-datasource-property name="URL">jdbc:oracle:thin:@localhost:1521:orcl10</xa-datasource-property> <xa-datasource-property name="User"> xxxx </xa-datasource-property> <xa-datasource

I have a DataGridView with custom columns. But when I add a " DataGridViewComboBoxColumn " and give to it a list of my model class as DataSource then I had the following error: System.ArgumentException: DataGridViewComboBoxCell value is not valid. New EDIT: 4/9/2009 "More Details" I've a class called SmsPart has these properties: public class SmsPart { public int ID public SmsPart Parent public string Name // and more } I've method called " GetSmsParts " return " List<SmsPart> ". I want the Parent column in the DataGridView to be ComboBoxColumn to select which part is the parent of selected

I have to bind a Dropdownlist with coutries which should be grouped by region, I have found a sample code from the following link, http://www.codeproject.com/KB/custom-controls/DropDownListOptionGroup.aspx?msg=3984074#xx3984074xx I wanted the country list same as this. But problem is that I want to bind the dropdownlist from sql result. I have tried the following but didn't work, ddlCountry.DataSource = CountryDtoCollection; ddlCountry.DataBind(); ddlCountry.Attributes.Add("OptionGroup", "Region"); any one knows any solution for this. you can write a custom server control and use the data

I have a JPA application that has specified JTA transactions in persistence.xml. For whatever reason, I have found that when using JTA, you MUST specify a JNDI data source within persistence.xml as well. This is fine, unless you are trying to go integration testing outside a container and JNDI is not available. My questions are: a) is there anyway to inject a jdbc datasource into my JTA transaction manager? b) if not, how do a handle a JNDI lookup during integration testing? Edit: The error I get when firing up the integration test is: Caused by: org.springframework......

I'm asking for elements that have a recursive relationship in one table: child id | parent id 1 | null 2 | 1 3 | 1 4 | 2 And so on...To ask for this whole datastructure it takes about 10 secondsAt the moment I can't redesign this table because it cost too much time (for more information: Spring Repository performance issues with recursive ORM Class ) Now, I am thinking about preloading all data during spring startup in a bean, so that the client "communicates" with the bean and I update the data in bean and database. I think it doesn't matter how long this startup takes, but it matters how
