JCO Server implementation questions

Hi experts,

I want to try to create a JCO Server with the JCO 3 library.

I'm kinda lost in all the links I've found since there is still a lot of things from the JCO 2 on the internet and I don't understand everything I'm doing.

Please note that there is already a working Java JCO server with old IBM tools and we need to migrate to JCO 3.

So here are my questions :

What do I have to do exactly in the sm59 transaction ?

Here is what I get in the RSGWLST transaction http://i.imgur.com/IRgAyO8.pnghttp://i.imgur.com/YyfDQbt.png (Loic-PC is my machine so I guess my java jco server is up.) Is everything ok ?

I have followed this link (Java Program for Creating a Server Connection - Components of SAP Communication Technology - SAP Library) to create my java jco server. What exactly are ServerDataProvider.JCO_GWHOST, ServerDataProvider.JCO_GWSERV and above all ServerDataProvider.JCO_PROGID)

How do I testmy Java JCO server ? I understood that I have to call STFC_TRANSACTION in se37 where I put my jco destination (previously set up in sm59 ?) and a string but I have a dump when I'm tying that.

I hope someone can help me, everything is still really blurry to me.

Regards

Here is the code I use to try to connect :

    static String SERVER_NAME1 = "JCO_SERVER";

    static String DESTINATION_NAME1 = "ABAP_AS_WITHOUT_POOL";

    static String DESTINATION_NAME2 = "ABAP_AS_WITH_POOL";

    static

    {

        Properties connectProperties = new Properties();

        connectProperties.setProperty(DestinationDataProvider.JCO_ASHOST, "172.16.200.114");

        connectProperties.setProperty(DestinationDataProvider.JCO_SYSNR,  "00");

        connectProperties.setProperty(DestinationDataProvider.JCO_CLIENT, "500");

        connectProperties.setProperty(DestinationDataProvider.JCO_USER,   "develop2");

        connectProperties.setProperty(DestinationDataProvider.JCO_PASSWD, "passw0rd");

        connectProperties.setProperty(DestinationDataProvider.JCO_LANG,   "en");

        createDataFile(DESTINATION_NAME1, "jcoDestination", connectProperties);

        connectProperties.setProperty(DestinationDataProvider.JCO_POOL_CAPACITY, "3");

        connectProperties.setProperty(DestinationDataProvider.JCO_PEAK_LIMIT,    "10");

        createDataFile(DESTINATION_NAME2, "jcoDestination", connectProperties);

       

        Properties servertProperties = new Properties();

        servertProperties.setProperty(ServerDataProvider.JCO_GWHOST, "sapdevdb02");

        servertProperties.setProperty(ServerDataProvider.JCO_GWSERV, "sapgw00");

        servertProperties.setProperty(ServerDataProvider.JCO_PROGID, "JCOServer");

        servertProperties.setProperty(ServerDataProvider.JCO_REP_DEST, "ABAP_AS_WITH_POOL");

        servertProperties.setProperty(ServerDataProvider.JCO_CONNECTION_COUNT, "2");

        createDataFile(SERVER_NAME1, "jcoServer", servertProperties);

    }
