BAPI_DOCUMENT_CHECKOUTVIEW2 with JCo3

257 Views

Hey all,

i´m facing "little" problems with checking out documents via BAPI_DOCUMENT_CHECKOUTVIEW2 and JCo 3.0.2 (JCo 3.0.4 is not working, but thats another topic!)

We´re running a standalone Java server - one task is to check out documents. On our server, we don´t have any SAP-GUI installed, so i put the two files sapftp.exe and saphttp.exe to windows path variable.

What´s running fine with JCo 2.1.8 is failing now - without any error message!!! When i call the BAPI via se37 from another system, the checkout works fine, so the document is valid.

My coding is:

JCoFunction function = dest.getRepository().getFunction("BAPI_DOCUMENT_CHECKOUTVIEW2");

if(function!=null){

JCoParameterList importParameterList = function.getImportParameterList();

JCoStructure documentfile = importParameterList.getStructure("DOCUMENTFILE");

documentfile.setValue("APPLICATION_ID","4B0D068FFF20D611859800902761A739");

documentfile.setValue("FILE_ID","4E0D068FFF20D611859800902761A739");

documentfile.setValue("ORIGINALTYPE","2");

importParameterList.setValue("DOCUMENTTYPE","DES");

importParameterList.setValue("DOCUMENTNUMBER","TESTME");

importParameterList.setValue("DOCUMENTPART","000");

importParameterList.setValue("DOCUMENTVERSION","00");

importParameterList.setValue("GETSTRUCTURE","1");

importParameterList.setValue("GETCOMPONENTS","X");

importParameterList.setValue("GETHEADER","X");

importParameterList.setValue("ORIGINALPATH","D:

TEMP

SAP

");

importParameterList.setValue("HOSTNAME","abcdefg");

importParameterList.setValue("PF_FTP_DEST","SAPFTPA");

importParameterList.setValue("PF_HTTP_DEST","SAPHTTPA");

function.execute(dest);

........

Unfortunately, i don´t get any results! Is checking out generally possible with JCo3?

I would be very grateful for any help you would offer to me on this subject.

regards ... Ralf
