                                          java.rmi.RemoteException

Starts a new Config Instance on the Server with the configuration given.

 var session = sf.createSession();
 var pass = "Difficult password";
 session.startConfigInstance("testconfig.xml", false, pass, "myrunname", "mystore=mynewstore.properties");
 

Parameters:

configPathOrSolutionName - The URL where the configuration file is loaded from or the Solution Name of the configuration file. Only configuration files located in the configuration codebase folder can be referenced by Solution Name.

keepAlive - When true the Config Instance will stay alive even when no threads are running, when false the Config Instance will automatically terminate when its last thread terminates.

password - Specify the password of the configuration when it is password-protected; specify null when the configuration is not password-protected.

runName - A name which will be used as the configuration instance id. It must not coincide with any of the ids of running configuration instances. It must be a valid file name on the file system, on which TDI is running, because the configuration instance id (which is the same as the run name) is used when storing certain configuration-instance-specific information, such as the System Logs. To avoid file system problems, TDI forbids the following symbols to appear inside a run name: '\' '/' ':' '*' '?' '"' '<' '>' '|'. The run name is an optional parameter that can be null.

overrideProps - Use to redirect property stores to load their contents from files different from the ones specified in the configuration file. Property stores and their corresponding files are specified as key-value pairs separated with spaces, e.g.: "mystore1=file1.properties mystore2=file2.properties". You cannot override a property store from an included configuration file, because its property stores are not directly accessible in the including file. This is an optional parameter that can be null.

Returns:

ConfigInstance object representing currently started configuration instance.

Throws:

DIException - If an error occurs on starting the new Config Instance or if the run name contains any of the following symbols: '\' '/' ':' '*' '"' '<' '>' '|'.

java.rmi.RemoteException - if a communication-related exception occurs.

                            java.rmi.RemoteException

Releases the lock on the specified configuration, thus aborting all changes being done. This call can only be executed from a user that has previously checked out the configuration and only if the configuration lock has not timed out.

Parameters:

relativePathOrSolutionName - The path to the configuration relative to the Server configuration codebase folder or the Solution Name of the configuration (the configuration must be inside the configuration codebase folder).

Returns:

true if the undo operation is successful, false otherwise.

Throws:

If a new configuration file is added in the configuration codebase folder when the Server is already running, that configuration will not be listed by the method.

Example:

        var sf = java.rmi.Naming.lookup("rmi://127.0.0.1:1099/SessionFactory");
        var session = sf.createSession();

Returns a list all configurations in the directory subtree of the Server configuration codebase folder. If a configuration has a Solution Name, this name appears in the list, otherwise in the list appears the file path of the configuration. The configurations file paths returned are relative to the TDI Server configuration codebase folder. The returned list is based on information, gathered by the Server on startup. If a new configuration file is added in the configuration codebase folder when the Server is already running, that configuration will not be listed by the method.

invokeCustom

java.lang.Object invokeCustom(java.lang.String aCustomClassName,
                              java.lang.String aMethodName,
                              java.lang.Object[] aParams)
                              throws DIException,
                                     java.rmi.RemoteException

Invokes the specified method from the specified class. The method must be static. This method cannot invoke methods with null parameter values. All parameter values in the parameter object array MUST be non-null. If any value is null an Exception is thrown. If a user wants to invoke a method with a null parameter, he/she must use the other invokeCustom method. The usage of this method can be turned on/off. There is a property in the global.properties file called api.custom.method.invoke.on. If this property is set to true then this method can be invoked, otherwise an exception is thrown if this method is invoked. There is a restriction on the classes which can be directly invoked. The allowed classes are described in another property in the global.properties file called api.custom.method.invoke.allowed.classes. Only classes listed in this property can be directly invoked by this method. If a user tries to invoke a class which is not in this list then an exception is thrown.

Example: Suppose the following class is packaged in a jar file, which is then placed in the 'jars' folder of TDI:
public class MyClass {
public static Integer multiply(Integer a , Integer b){
return new Integer(a.intValue() * b.intValue());
}
}
Suppose the global.properties TDI configuration file contains the following lines:
api.custom.method.invoke.on=true
api.custom.method.invoke.allowed.classes=MyClass
Now we can do the following:

 var sf = java.rmi.Naming.lookup("rmi://127.0.0.1:1099/SessionFactory");
 var session = sf.createSession();
 var result = session.invokeCustom("MyClass", "multiply", new Array(3, 5));
 

Parameters:

aCustomClassName - The class containing the method to be invoked.

aMethodName - The name of the method to be invoked.

aParams - Array of parameters used by the invoked method.

Returns:

the result of dispatching the method represented with parameters aParams

Throws:

DIException - If an error occurs while invoking the method.

java.rmi.RemoteException - If a communication-related exception occurs.

invokeCustom

                              java.lang.String[] aParamsClass)
                              throws DIException,
                                     java.rmi.RemoteException

Invokes the specified method from the specified class. The method must be static. This method is used when the user wants to invoke the specified method with a null parameter value. The main difference between these two invokeCustom methods is that when using this method the user MUST specify the parameters' type. The usage of this method can be turned on/off. There is a property in the global.properties file called api.custom.method.invoke.on. If this property is set to true then this method can be invoked, otherwise an exception is thrown if this method is invoked. There is a restriction on the classes which can be directly invoked. The allowed classes are described in another property in the global.properties file called api.custom.method.invoke.allowed.classes. Only classes listed in this property can be directly invoked by this method. If the user tries to invoke a class which is not in this list then an exception is thrown.

Example: Suppose the following class is packaged in a jar file, which is then placed in the 'jars' folder of TDI:
public class MyClass {
public static Integer multiply(Integer a , Integer b){
return new Integer(a.intValue() * b.intValue());
}
}
Suppose the global.properties TDI configuration file contains the following lines:
api.custom.method.invoke.on=true
api.custom.method.invoke.allowed.classes=MyClass
Now we can do the following:

 var sf = java.rmi.Naming.lookup("rmi://127.0.0.1:1099/SessionFactory");
 var session = sf.createSession();
 var result = session.invokeCustom("MyClass", "multiply", new Array(3, 5), new Array("java.lang.Integer", "java.lang.Integer"));
 

Parameters:

aCustomClassName - The class containing the method to be invoked.

aMethodName - The name of the method to be invoked.

aParamsValue - Array of parameters used by the invoked method.

aParamsClass - The type of the parameters used by the invoked method.

Returns:

the result of dispatching the method represented with parameters' types aParamsClass.

Throws:

DIException - If an error occurs while invoking the method.

java.rmi.RemoteException - If a communication-related exception occurs.
