DSServerType (Smart GWT EE API 14.0p (2026-01-20))

java.lang.Object
- java.lang.Enum<DSServerType>
- - com.smartgwt.client.types.DSServerType

All Implemented Interfaces:

ValueEnum, java.io.Serializable, java.lang.Comparable<DSServerType>
```
public enum DSServerType
extends java.lang.Enum<DSServerType>
implements ValueEnum
```
Indicates what Smart GWT Server will do with a DataSource request if you call dsRequest.execute() in server code.
If you use a Java-based persistence layer not provided by Smart GWT, such as EJB or your own custom object model, you don't need to set dataSource.serverType and should follow the integration instructions.

Enum Constant Summary

Enum Constants
Enum Constant and Description
`GENERIC` Requests will be delivered to the server and you are expected to write Java code to create a valid response.
`HIBERNATE` Use Hibernate, either using a real mapped bean or by automatically generating a Hibernate configuration based on a Smart GWT DataSource file (dataSourceID.ds.xml).
`JPA` Use Smart GWT's built-in JPA 2.0 connector.
`JPA1` Use Smart GWT's built-in JPA 1.0 connector.
`ODATA` Use Smart GWT's built-in `OData DataSource`.
`PROJECTFILE` Requests will be delivered to the server and processed as `FileSource operations`, using directories or other DataSources which you configure via `DataSource.projectFileKey` or `DataSource.projectFileLocations`
`REST` Use Smart GWT's built-in `RestConnector`, which can connect to many different types of REST webservice
`SQL` Use Smart GWT's `built-in SQL connectors` to talk directly to relational databases.
`UNION` Use Smart GWT's built-in `unionDataSource`, which assimilates records from multiple member dataSources

- Enum Constant Detail
  - SQL
```
public static final DSServerType SQL
```
    Use Smart GWT's built-in SQL connectors to talk directly to relational databases.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "sql".
  - HIBERNATE
```
public static final DSServerType HIBERNATE
```
    Use Hibernate, either using a real mapped bean or by automatically generating a Hibernate configuration based on a Smart GWT DataSource file (dataSourceID.ds.xml). See HibernateIntegration for details.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "hibernate".
  - JPA
```
public static final DSServerType JPA
```
    Use Smart GWT's built-in JPA 2.0 connector.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "jpa".
  - JPA1
```
public static final DSServerType JPA1
```
    Use Smart GWT's built-in JPA 1.0 connector.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "jpa1".
  - REST
```
public static final DSServerType REST
```
    Use Smart GWT's built-in RestConnector, which can connect to many different types of REST webservice
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "rest".
  - ODATA
```
public static final DSServerType ODATA
```
    Use Smart GWT's built-in OData DataSource. This is a specialized subclass of the RestConnector which adds functionality for REST webservices that follow the OData protocol
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "odata".
  - GENERIC
```
public static final DSServerType GENERIC
```
    Requests will be delivered to the server and you are expected to write Java code to create a valid response. Throws an error if the server side method dsRequest.execute() is called. This is appropriate if you intend an entirely custom implementation, and you want an error thrown if there is an attempt to call an operation you have not implemented.
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "generic".
  - PROJECTFILE
```
public static final DSServerType PROJECTFILE
```
    Requests will be delivered to the server and processed as FileSource operations, using directories or other DataSources which you configure via DataSource.projectFileKey or DataSource.projectFileLocations
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "projectFile".
  - UNION
```
public static final DSServerType UNION
```
    Use Smart GWT's built-in unionDataSource, which assimilates records from multiple member dataSources
    If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "union".
- Method Detail
  - values
```
public static DSServerType[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (DSServerType c : DSServerType.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static DSServerType valueOf(java.lang.String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
    
    java.lang.NullPointerException - if the argument is null
  - getValue
```
public java.lang.String getValue()
```
    Specified by:
    
    getValue in interface ValueEnum
