11.4  Getting information from the database 

By default, all the fields present on JSP pages are connected to a corresponding field in some database file. 

You can also get information from the database by using XfijSource component's methods like 

getExternalValue

 and creating a getter method. For example if you want a read only field (like 

NAME

) 

to be present in your JSP file: 

Create a method in Java source code: 

public String getName() { 

 return mySource.getExternalValue( .01 ); 

} 

Add a tag to your JSP file: 

<%= myBean.getName()%> 

11.5  Customizing grids 

Two dimensional grids such as above are created using a model driven architecture in e FixIT. Basically, a 

model is used to format grid data into a two dimensional 

 element. This means you 

can replace the built in grid model with a custom one. There are 

three

 kinds of built in grids in e FixIT 4.2: 

finderGridModel

 which is used in queries to display query results as a grid. You can select a new 

model by calling in application Java code:

setFinderGridModel(newClass) 

where 

newClass

 is the class object of the new model. 

gridModel

 which is used to display ordinary grids such like the one above. You can select a new 

model by calling in application Java code:

setGridModel(newClass) 

where 

newClass

 is the class object of the new model.
