Calling as400 system from Java

I am calling as400 system from Java. I am able to connect to a program of as400 system but not able to get the output data. It is giving me empty message.
AS400 as400 = new AS400("as242g.na.sysco.net", "dprint", "dprint");
System.out.println(as400);
ProgramParameter[] parameters=new ProgramParameter[4];
AS400Text opcoText=new AS400Text(3,as400);
AS400Text emoptyText=new AS400Text(1,as400);
AS400Text indicatorText=new AS400Text(1,as400);
parameters[0]=new ProgramParameter(opcoText.toBytes("056"));
parameters[1]=new ProgramParameter(emoptyText.toBytes(" "));
parameters[2]=new ProgramParameter(indicatorText.toBytes("Y"));
parameters[3] = new ProgramParameter(10);
String fullProgramName = "/QSYS.LIB/SCSUINT.LIB/DPIM10CL.PGM";
System.out.println(fullProgramName);
ProgramCall programCall=new ProgramCall(as400);
try {
programCall.setProgram(fullProgramName,parameters);
if (programCall.run()) {
System.out.println("run");
AS400Text text1 = new AS400Text(10,as400);
String message=(String) text1.toObject(parameters[3].getOutputData());
System.out.println(message);
}
else {
System.out.println("false");
}
} catch (PropertyVetoException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (AS400SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ErrorCompletingRequestException e) {

Any working example for org.netbeans.lib.cvsclient.command.diff.DiffCommand

I want to find out differences between two revisions using org-netbeans-lib-cvsclient-RELEASE712.jar.
any working example?
DiffCommand diffCommand = new DiffCommand();
diffCommand.setRecursive(true);
diffCommand.setRevision1("rel-2230");
diffCommand.setRevision2("rel-2240");
diffCommand.setFiles(new File[]{new File("D:/test/")});
diffCommand.setBuilder(new SimpleDiffBuilder(em, diffCommand));
try {
System.out.println(diffCommand.getCVSCommand());
cvsClient.executeCommand(diffCommand, opts);
Set files = cvsClient.getAllFiles(new File("D:/test/"));
} catch (CommandException | AuthenticationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();

Sync dropbox file for android

I was wondering why my file is not updating to dropbox. Currently it only creates the an empty file.
final String TEST_FILE_NAME = DateTime + ".txt";
DbxPath path = new DbxPath(DbxPath.ROOT, TEST_FILE_NAME);
try {
if (!FileSystem.exists(path)) {
newFile = FileSystem.create(path);
try {
newFile.writeString("Hello world!");
} finally {
newFile.update();
newFile.close();
}
}
} catch (DbxException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}

Solved: I never unlinked my dbxacc and kept relinking, causing errors to show up! Silly mistake.

Android - Facebook: an active access token must be used to query information about the current user

i'm using this code:
if(!facebook.isSessionValid()) {
try {
String jsonUser = facebook.request("me");
obj = Util.parseJson(jsonUser);
String id = obj.optString("id");
String name = obj.optString("name");
tv1.setText("sodfnsdf");
} catch (MalformedURLException e) {
tv1.setText("1");
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
tv1.setText("2");
// TODO Auto-generated catch block
e.printStackTrace();
} catch (FacebookError e) {
tv1.setText("3");
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JSONException e) {
tv1.setText("4");
// TODO Auto-generated catch block
e.printStackTrace();
}
}
else {
tv1.setText("Error");
}
i've searched online and in stackoverflow, but cannot find the answer to my question, i only found very similiar questions but different in some ways..

Hey you need to call facebook.authorize method
if(!facebook.isSessionValid()) {
facebook.authorize() }
For more information you can refer this link. I think it will help you.
