                                   throws DIException,
                                          java.rmi.RemoteException
Starts a new Config Instance on the Server with the configuration given.

Example:

 var sf = java.rmi.Naming.lookup("rmi://127.0.0.1:1099/SessionFactory");
 var session = sf.createSession();
 var pass = "Difficult password";
 session.startConfigInstance("testconfig.xml", false, pass, "myrunname", "mystore=mynewstore.properties");
 

Specified by:
startConfigInstance in interface Session
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.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));
 

Specified by:

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.

                                     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"));
 

Specified by:

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.
runName - A name which will be used as the configuration instance id. It must not coincide with any of the id's of running configuration instances. It must not contain forward or back slashes or colons. This 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. 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, because its property stores are not directly accessible. This is an optional parameter that can be null.
Returns:
A handle to the started configuration instance.
Throws:
DIException - If an error occurs on starting the new Config Instance or if the run name is not a valid file name.
java.rmi.RemoteException - If a communication-related exception occurs.

startConfigInstance

public ConfigInstance startConfigInstance(java.lang.String configPathOrSolutionName,
                                          boolean keepAlive,
                                          java.lang.String password,
                                          java.lang.String runName,
                                          java.lang.String overrideProps,
                                          LogListener logListener)
                                   throws DIException,
                                          java.rmi.RemoteException
Starts a new Config Instance on the Server with the configuration given.

Example:

 var sf = java.rmi.Naming.lookup("rmi://127.0.0.1:1099/SessionFactory");
 var session = sf.createSession();
 var pass = "Difficult password";
 session.startConfigInstance("testconfig.xml", false, pass, "myrunname", "mystore=mynewstore.properties", null);
 

Specified by:
startConfigInstance in interface Session
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.
logListener - Listener for messages logged by the configuration instance.
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.
