Method Detail

step1Connect

public static void step1Connect()
                         throws JCoException

This example demonstrates the destination concept introduced with JCO 3. The application does not deal with single connections anymore. Instead it works with logical destinations like ABAP_AS and ABAP_MS which separates the application logic from technical configuration.

Throws:

JCoException

step2ConnectUsingPool

public static void step2ConnectUsingPool()
                                  throws JCoException

This example uses a connection pool. However, the implementation of the application logic is still the same. Creation of pools and pool management are handled by the JCo runtime.

Throws:

JCoException

step3SimpleCall

public static void step3SimpleCall()
                            throws JCoException

The following example executes a simple RFC function STFC_CONNECTION. In contrast to JCo 2 you do not need to take care of repository management. JCo 3 manages the repository caches internally and shares the available function metadata as much as possible.

Throws:

JCoException

step3WorkWithStructure

public static void step3WorkWithStructure()
                                   throws JCoException

ABAP APIs often uses complex parameters. This example demonstrates how to read the values from a structure.

Throws:

JCoException

step4WorkWithTable

public static void step4WorkWithTable()
                               throws JCoException

A slightly more complex example than before. Query the companies list returned in a table and then obtain more details for each company.

Throws:

JCoException

step4SimpleStatefulCalls

public static void step4SimpleStatefulCalls()
                                     throws JCoException

this example shows the "simple" stateful call sequence. Since all calls belonging to one session are executed within the same thread, the application does not need to take into account the SessionReferenceProvider. MultithreadedExample.java illustrates the more complex scenario, where the calls belonging to one session are executed in different threads. Note: this example uses Z_GET_COUNTER and Z_INCREMENT_COUNTER. Most ABAP systems contain function modules GET_COUNTER and INCREMENT_COUNTER that are not remote-enabled. Copy these functions to Z_GET_COUNTER and Z_INCREMENT_COUNTER (or implement as wrapper) and declare them to be remote enabled.

Throws:

JCoException

main

public static void main(String[] args)
                 throws JCoException

Throws:

JCoException
