BRBACKUP for Java

Hello,
We have a dual stack BI 7.0 system.
I just wanted to know, whether brbackup will take a backup of both - ABAP+JAVA?
Can I use this backup to restore the system or do a homogeneous system copy?
Thanks.

Why brbackup should take a backup of the "Java filesystem binaries"?
it is a tool designed to make a backup of the ORACLE database. Last time I look, the "Java filesystem binaries" are not part of the ORACLE database.
I think it can take a backup of those files, but you have to use some non standard commands.
I'll check the documentation (I do not have a JAVA system so I'm talking by heart)
NOTE: Checking the documentation si something very interesting, you can learn a lot and it is something you were told some times in this post.
You can try it ;-p
UPDATE:
No more than 5 mintutes to find the info in the documentation
not bad.
First. The general information about [brbackup|http://help.sap.com/saphelp_nwpi71/helpdata/en/47/1d9aa98ffb2c7be10000000a114a6b/frameset.htm]
This SAP tool for the Oracle database enables you to back up database files.
Second. You can make also make backups of [non database files|http://help.sap.com/saphelp_nwpi71/helpdata/en/47/1db341b0a12c8de10000000a114a6b/frameset.htm] but
Non-database files should only be backed up with BRBACKUP after an SAP upgrade or an Oracle upgrade. This backup method is not a replacement for a file system backup using operating system features.
That should answer your last question

Step by step installation for java card kit 2.2.2

can anyone help me with a complete step by step installation information for java card kit 2.2.2, i already tried to follow the instruction given in the software i download n still stuck in setting the java path. any recommendation
thanks for the help

The javacard API is for developing applets on card. Java 6 is for developing clients off-card.
yes u can use any java IDEs like netbeans or jcreator. But you will have to select the libraries within the downloaded java card kit folder for ur IDE in order to compile successfully.
try reading up the documentation and run the samples in the java card kit. thats a good place to start.

XModem via TCP for Java

I am sure that many of you experienced developers have read requests in the past concerning implmentation of Ward Christenen's XModem protocol over a TCP socket. If not, well... you are about to...
This is a major hack... but it is starting to come together... thanks to Fred Potter for his source code to start this project...
Objective:
Basically, I want to create a console application which accepts an incoming connection and starts the receive mode for a XModem file transfer. I am using CGTerm (for Commodore retrocomputing) but can test with HyperTerminal as well...
The user who connects to the server selects SEND and the FILE to send for a XModem file transfer... and the transfer begins...
The incoming blocks of 128 bytes are written to a file
After the transfer is over the server disconnects the client terminal.
Here is what I have so far:
import java.net.*;
import java.lang.*;
import java.io.*;
// X-Modem Server implementation via TCP/IP socket
public class XServer {
public static FileWriter fw;
public static void main(String[] args) throws IOException {
// define the file
try {
fw = new FileWriter("filename.txt");
} catch (Exception e) {
System.out.println(e);
System.exit(0);
int port = Integer.parseInt(args[0]);
ServerSocket server = new ServerSocket(port);
System.out.println("X-Server v1.0 - waiting for connection");
Socket client = server.accept();
// Handle a connection and exit.
try {
InputStream inputStream = client.getInputStream();
OutputStream outputStream = client.getOutputStream();
new PrintStream(outputStream).println("Go to send file mode!"); // sent to client
System.out.println("Ready to receive file via X-Modem...");
* BEGIN TRANSFER HERE!
// set the debug flag
XModem.debug = true;
* Here we are instantiating a new InputStream that represents the remote
* file that we are receiving. In this single line we are attempting to
* start the flow.
* Behind The Scenes: We're sending a NAK across the serial line repeatedly
* until we finaly start seeing the data flow. If we don't see the data
* flow, then we throw an exception.
System.out.println("Sending NAK to start receive mode...");
InputStream incomingFile;
try {
incomingFile = new XModemRXStream(inputStream, outputStream);
} catch (IOException e) {
System.out.println("ERROR! Unable to start file transfer!");
e.printStackTrace();
return;
System.out.println("Starting file transfer...");
* Here we are reading from the incoming file, byte by byte, and printing out.
* Behind The Scenes: Internally, the read() method is handling the task of
* asking for the next data block from the remote computer, processing it (i.e.
* parsing, running checksums), and then putting it in an internal buffer. Not
* all calls to read() will request a new data block as each block contains at
* least 128 bytes of data. Sometimes you will only hit the buffer.
try {
for (;;) {
int c = incomingFile.read();
if (c==-1)
break; // End of File
// print character / byte
System.out.print(c+",");
// write to file
try {
//System.out.print(".");
fw.write(c);
} catch (Exception e) {
System.out.println(e);
System.exit(0);
} catch (IOException e) {
System.out.println("error while reading the incoming file.");
e.printStackTrace();
return;
// done
System.out.println("File sent.");
new PrintStream(outputStream).println("");
new PrintStream(outputStream).println("transfer successful!");
} finally {
//client.close();
// save the file
try {
fw.close();
System.out.println("file saved.");
} catch (Exception e) {
System.out.println(e);
System.exit(0);

Can someone help me along here... I have been trying to figure out how to do this for approx. a year or so... it has been a very slow process.
I could use a guru to help me out so I can write the upload and download routines for my Commodore BBS PETSCII Emulation Server.
Visit http://www.retrogradebbs.com for details.
Thanks.
Please help out a dedicated developer who is in over his head...

Ok. Fair enough. What about general information about Xmodem. This is a hard project because of how obscure the legacy technology is that I am having to implement using Java and MySQL.
I have two major issues which I have to figure out how to troubleshoot and debug, if possible.
1. The 23+ blocks exception when a file is being received
2. The exception which is thrown immediately if I try to receive a binary file instead of an ASCII file.
I read that telnet is a 7-bit technology and that is why Xmodem, which is an 8-bit technology is not that popular as a viable protocol via telnet, whereas Kermit is, since it was developed for 7-bit systems, i.e. mainframes and minicomputers.
Is this correct?
If that is the case, why does www.serio.com have a viable X-Y-ZModem library available (for several hundred $$$ of course) which can be used with both RS-232 serial ports and TCP socket ports? Obviously, it can be done. They are the ONLY company with this library for sale for Java to do this. I cannot justify that $$$ amount for a mere hobby (writing the BBS emulation server for supporting Commodore PETSCII (CG) callers via CGTerm or a native C-64 terminal program using Jim Brain's TCPSER middleware, which emulates a Hayes modem via telnet for telBBSing/retrocomputing.
I really want to learn how to implement a file transfer protocol, since back in the 80s, I used Xmodem, Punter, Y/Z Modem, etc., a lot to upload and download files via modem at baud rates of 2400, 14.4, 19.2, and 38.4, respectively.
It's fun to learn how the old skool gurus of telecommunications technology did it. It is one thing to run a BBS which supports these technologies and features, and it is an entirely other thing to learn how to design and develop them yourself for implementation into a project such as I taken on.
It CAN be done. It WILL be done. However, I have just started my exhaustive research on how it needs to be done. I have read up as much as I could on XModem by Ward C., the father of the protocol.
But, I have no information to help me figure out why the communications are acting as they do so far.
Can someone please download the xserver.zip file on my website at:
www.retrogradebbs.com/projects/xserver.zip
Compile it. Run it. Connect using HyperTerminal, Netrunner, or another telnet terminal emulation program which supports Xmodem file transfers using WinSock.
See what happens. With finals due in the next two days, this project will have to be put on hold until after I submit my two final projects.
If anyone knows what needs to be done to support both ASCII and BINARY file transfers via Xmodem via a socket instead of a modem with RTS/CTS hardware flow control, please respond.
I know for a fact that this can be done.

can u help me regarding that....
Thanks in advanceI wonder how that would work then. Let's take a fictive example. You have a class com.mycompany.myapp.Foo. This would mean that the class is stored in some directory like this:
c:/webrootdir/myapp/WEB-INF/classes/com/mycompany/myapp/Foo.classTo be able to run such a class from the commandline using Java, you would have to invoke this command:
java -cp c:/webrootdir/myapp/WEB-INF/classes com.mycompany.myapp.FooHow would knowing the exact path to this class help you?

How to create a report with data using the Crystal Reports for Java SDK

Hi,
How do I create a report with data that can be displayed via the Crystal Report for Java SDK and the Viewers API?
I am writing my own report designer, and would like to use the Crystal Runtime Engine to display my report in DHTML, PDF, and Excel formats. I can create my own report through the following code snippet:
ReportClientDocument boReportClientDocument = new ReportClientDocument();
boReportClientDocument.newDocument();
However, I cannot find a way to add data elements to the report without specifying an RPT file. Is this possible? I seems like it is since the Eclipse Plug In allows you to specify your database parameters when creating an RPT file.
is there a way to do this through these packages?
com.crystaldecisions.sdk.occa.report.data
com.crystaldecisions.sdk.occa.report.definition
Am I forced to create a RPT file for the different table and column structures I have?
Thank you in advance for any insights.

Hi Rameez,
After working through the example code some more, and doing some more research, I remain unable to populate a report with my own data and view the report in a browser.

com.crystaldecisions.sdk.occa.report.lib.ReportSDKException: java.lang.NullPointerException---- Error code:-2147467259 Error code name:failed
There was other sample code on SDN which suggested the following - adding the table after calling table.setDataFields() as in:
          String tableName = "Building";
            String fieldname = "Building_Name";
            Table oTable = new Table();
            oTable.setName(tableName);

            field.setLength(40);
            fields.add(field);

            oTable.setConnectionInfo(oConnectionInfo);
            rcd.getDatabaseController().addTable(oTable, null);
This code succeeds, but it is not clear how to add that database field to a section. If I attempt to call the following:
FieldObject oFieldObject = new FieldObject();
            oFieldObject.setDataSourceName(field.getFormulaForm());
            oFieldObject.setFieldValueType(field.getType());
            // Now add it to the section
            oFieldObject.setLeft(3120);
            oFieldObject.setTop(120);
            oFieldObject.setWidth(1911);
            oFieldObject.setHeight(226);
            rcd.getReportDefController().getReportObjectController().add(oFieldObject, rcd.getReportDefController().getReportDefinition().getDetailArea().getSections().getSection(0), -1);
Then I get an error (which is not unexpected)
com.crystaldecisions.sdk.occa.report.lib.ReportDefControllerException: The field was not found.---- Error code:-2147213283 Error code name:invalidFieldObject
How do I add one of the table.SetDataFields() to my report to be displayed?
Are there any other pointers or suggestions you may have?
Thank you

I just ran a software update for Java and MacBook Pro SMC, now my Mini Display Port to HDMI TV is not working. The TV is flickering. The Mac Display is fine.

I was just watching / streaming TV off Safari on my actual TV.
I'm using a Mini-Display Port to HDMI cable for the connection to the external display.
Software update popped-up and said there was an update for Java and for SMC.
I ran the update and upon the computer restarting, my external display (my TV) is no longer working. It is now flickering.
It won't work in Mirroring or set up as an extended display.
I've reset SMC / PRAM / Safe Mode / Even restored from a Time Machine backup (From before the updates were done).
What could it be?!

I keep saying this over and over, in the hope that people who do a search will find it. Apple cannot possibly test for or be reponsible for the bazillion combinations of adapter, cables, and TV's out there. The only monitors that are 100% guaranteed to work with the MacBook Pro are the Cinema Displays and Thunderbolt Displays, because, they're made by Apple. They're expensive, but they work perfectly.
My guess is that you bought a cheap MDP to HDMI cable, or have a defective one. From my reading of these boards over the past few months, cheap cables have a high failure rate. And the regular priced ones have only a slightly less of one. Try a new one. Make sure you do not damage the Thunderbolt port.

Unable to Print Purchase order automatically using SAP GUI for JAVA

XDK for PL/SQL vs XDK for Java

Hi ,
I am trying to find what version of XDK and whether it is for java or PL/SQL. I am confused after what I saw in our environment. Please clarify..
When I run the getReleaseVersion() and do a
select xmlversion from dual,
I get
Oracle XDK Java 9.0.1.1.0A Production
Does this mean we have XDK for Java? not for PL/SQL?
I also see PL/SQL packages for XMLDOM,XMLGEN.XMLPARSER,XSLPROCESSOR,DBMS_XMLQUERY,DBMS_XMLSAVE.
Does this mean I have/not XDK for PL/SQL??
Please clarify.

XDK for PL/SQL is built based on XDK for Java. So that's why you got the result. It should also reflect the version you use.

For weeks I have been viewing a doggy day care via their web cam. This weekend I upgraded to Lion and have been unable to view the center since. I get an error message for java webcam class not found. All of my software is up to date--suggestions?

For weeks I have been viewing a doggy day care center via their web cam. This weekend I upgraded to Lion and have been unable to view the center. I get an error message for Java plug-in 1.6.0_29 ....webcam class not found. Any suggestions on how to fix this?

Sorry, don't know what else to suggest unless there's a URL to the problem stream that someone here can try. Otherwise we can't test it to try and determine what might be wrong.
BTW, make sure they're testing it with a Mac, not with a Windows system. If they test only with Windows, what they say is or is not working doesn't mean much.

Ebusiness Suite SDK for Java session management

Hi, I am trying to try sample java application mentioned in Oracle® E-Business Suite Software Development Kit for Java Release 11i and 12 Part No. E28169-02
Current version i am trying is Jdeveloper 11.1.1.4.0 and Ebiz suite 12.1.3
able to create Apps Data source with out any issue.
when Home.jsp is accessed through application menu, user name and all session related information is showing as NULL.
how to resolve this issue.

Hi Shay,
I gone through the webinar.
Here is more explanation of my issue.
I created Apps Data source earlier. That time i registered external node in ebusiness suite with node_name as ip_address of weblogic server.
But that time session details came as Null on sample Java application.
Then i realized that may be the issue and corrected registration of external node and corrected ebiz profile options accordingly.
When i tried to create Apps data source with fresh dbc file, i got into invalid username/pwd issue.
As per following forum discussion topic, hyphen and dots in host name will cause issue with Apps data source creation, which is confirmed by couple of discussion participants and Juan also.
https://kr.forums.oracle.com/forums/thread.jspa?threadID=2489849&start=30&tstart=0
My weblogic host name is like WL-SOADEV-01.domainname.com
what should be my further actions to resolve this issue.
Thanks

How to print line numbers in NWDS for Java?

Hi everyone,
does someone know how to print out program code with line numbers from the Netweaver Developer Studio for Java? This is inevitable for code reviews.
In Eclipse 3.4 this issue is solved. Is there possibly such a patch for NWDS as well?
Thanks,
Maria

Hi Pascal,
thanks for the quick reply. The setting you mention displays line numbers on the screen alright, but printing out does not work.
We use: SAP NetWeaver Developer Studio for SAP NetWeaver 7.1 SP06 PAT0000, Build id: 200807051938.
I guess it just does not work, because it was fixed only for Eclipse 3.4, and the above NWDS version bases on Eclipse 3.3.
What do you recommend for code inspections - copy/paste into PSPad or do you know a more comfortable practice?
Greetings
Maria

Can I Design a Forum with using web dynpro for java?

Hi All:
Can i design a forum with using web dynpro for java?
I want to design an application like a simple forum which maybe has many replies.So if i use
the UI technology "web dynpro for java", i will to create UI elements dynamically.How can i control this
dynamical UI elements to keep layout ?

Hi,
yes you can do that....
for exaple if you observe SDN...
you can imagine like....
A big Transparent Container(TC)....
Inside that number of other TCs(depending upon the question nd its replies...)....
In side each TC, again around 9 UIElements....
one for menioning what is the question/reply?
other for your description of question/reply...
other for your name,
displaing your fourm point... etc...
So it will be
for(loop till your (Question+No of replies))
Create Transparent Container....
Add Childs to the Container...
Decide your layout....
In case if you want to know how to create UIElements dynamically....

CALL FUNCTION 'BAPI_PO_CREATE1'
EXPORTING
    POHEADER                     = HEADER
    POHEADERX                    = HEADERX
POADDRVENDOR                 =
TESTRUN                      =
IMPORTING
EXPPURCHASEORDER             =
EXPHEADER                    =

i just want to know how can i fill these internal table in web dynpro
for java to create an application accessing "Bapi_po_create" .
Thanks

Hi Gopal,
I'm not sure what is your issue, it seems you're not really understanding how the Model structure works in WDP.
I'll assume few things here, like you know how to Import the Model into the WDP, and you know a little bit about what Java Classes will represent this Model in the Project.
Try these steps:
1. Import your Model into the Project;
2. Open your Component Modeler, create a Data Link between your Model / Component (Or Custom Controller, as you prefer)
- You can also use the "Apply Template -> Service Controler"
3. Map the Input of your Model as the Main Node, check the Input Tables (you prob. will have two, POITEM = ITEM - POITEMX = ITEMX)
4. Also, check the Return box, since this is BAPI return (You can use to display Backend messages)
Now you have the Model mapped into your Controller, you need to develop the Java function to execute it.
1. Create a new Input class, like
BAPI_PO_CREATE1_Input purchaseOrderCreateInput = new BAPI_PO_CREATE1_Input();
2. Bind your Input Node, in the Controller, with your Input Class;
wdContext.nodeBAPI_PO_CREATE1().bind(purchaseOrderCreateInput);
3. Set any Import parameters you need:
purchaseOrderCreateInput.setEXPPURCHASEORDER(XXXX);
4. To Add references to the Table, you will perform something like:
First, you need to know what "Structure" you need to add (POItem Structure) - You have a Java class that represents that Structure..
POITEM_Element poItemElement = new POITEM_Element();
poItemElement.setPROPERTY();   /// Set your Properties
purchaseOrderCreateInput.getPOITEM().add(poItemElement);
5. Execute your Input,
purchaseOrderCreateInput .execute();
Hope it helps,
Regards,
Daniel
