File Processing in Java

Hi
I am reading a file and depending on some conditions, I am writing to another file.Its working fine. But after reading the total file,I want to move the file pointer to the beginning of the same file. Is there any method to go the beginning of file?
Need help.
Please reply as soon as possible.

If you use RandomAcsessFile class, yes there is a method which can help you.

Hi,
I am using WLI 10.3 workshop to build process application. I have designed one JPD which inturn call another process JPD. So i have used worklist process control to create the process and tried to access the process. When i am executing the code, i am getting below error message.

Hi
Are you using wli process control?
That uses wsdl and could cause the issue.
I also saw couple of internal bugs CR264315 and CR288904 on the same issue on 9.2.
Since this is a wli issue could you post in the wli newsgroup to get more answers http://forums.bea.com/forum.jspa?forumID=2047 ?
Also you can open a BEA support case at http://support.bea.com and an wli support engineer would help you. Please refer to the Cr numbers above in your support case.

File processing failed with java.lang.StringIndexOutOfBoundsException:

Hi
I´m reading and sending files to an FTP server using SAP PI. I use file content conversion.
Everything has been working fine for months - but now the server was changes to a new host. The only thing changed was the host/user and pass.
But sending too the server fails with this error:
File processing failed with java.lang.StringIndexOutOfBoundsException: String index out of range: -27
Any body who has a clue??
Reading files works ok. And i can transfer files to the FTP server with FileZilla without problems.

Attempt to process file failed with java.lang.StringIndexOutOfBoundsExcep..

Hello All,
I am implementing file2file with file going from shared folder to FTPS server.
I am using TLS and X.509 certificate in file receiver communication channel.
when I implemented my scenario, this is the error its throwing :
Success : Connect to FTP server "my ftp address", directory "/TEST/"
Error : Attempt to process file failed with java.lang.StringIndexOutOfBoundsException: String index out of range: 3
I know this error is caused when java expects the 3 character length string and if its getting more than that... Does any faced this kindaa problem before...Any help is greatly appreciated....Obviously even points....
Thanks,
Ravi

There is no custom code at all? No mappings, no custom modules, no pre/post processing commands?
Also, check if you get this error when sending to ftps server without certificate (or with another certificate). It may be an incompatibility issue with certificate.
Did you import the .pfx (or .p12) file in KeyStorage Service?
Regards,
Henrique.

Hi,
The scenario is from Idoc to flat file and messages are getting processed successfully in XI. but in receiver communication channel error is coming:

Hi,
If you are using FTP then,
1. Make sure that the FTP sever does not have issues with Firewall or a Proxy server access.
2. Also verify that the specified FTP user ID has the necessary WRITE or overwrite authorization?

Invoking asynchronous BPEL process from java ui

Hi,
I am invoking an asynchronous BPEL process from java ui.
I read somewhere that i can obtain an instance handler uing the lookupInstance() method of class Locator using the conversation id provided by the class NormalizedMessage.
My code looks like this
// Connect to Oracle BPEL server
Locator locator = new Locator("default","bpel");
IDeliveryService deliveryService = (IDeliveryService)locator.lookupService(IDeliveryService.SERVICE_NAME );
// Construct a normalized message and send to Oracle BPEL Process Manager
NormalizedMessage nm = new NormalizedMessage();
nm.addPart("payload", xml);
// Initiate the BPEL process
deliveryService.post("MyLoanFlow", "initiate", nm);
//Obtain the instance handler
IInstanceHandle handle = locator.lookupInstance(NormalizedMessage.CONVERSATION_ID);
But this is giving the error - can not find any instance with conversation id 'conversationId'.
Also, if i try to obtain a list of instance handles associated with a process , it does not contain the most recently created instance
IBPELProcessHandle ph = locator.lookupProcess("MyLoanFlow");
IInstanceHandle[] iHandler = ph.listInstances();
out.println(iHandler.length + "<br>");
if i invoke the process for the first time the output is 0.
can you please help me. it is urgent.

Hi Sudipto,
Regarding your second question,
deliveryService.post("MyLoanFlow", "initiate", nm);
IBPELProcessHandle ph = locator.lookupProcess("MyLoanFlow");
IInstanceHandle[] iHandler = ph.listInstances();
out.println(iHandler.length + "<br>");
---- returns 0 ---
This is because MyLoanFlow is an asynchronous process in your case. So the control is returned to your java block immediately after the request for a new instance is posted. And your second line of code(querying for the list of instances) is executed even before the instance is created on the server side. You can verify this in two ways:
1. try creating an instance of a synchronous process using IDeliveryService.request - this will always result in the increment since the current thread is blocked till the new instance is created.
2. for your case, you can try
Thread.currentThread().sleep(500); - just allow the server some time for completing the instance before you query it for the list of instances..
and wrt question 1,
//Obtain the instance handler
IInstanceHandle handle = locator.lookupInstance(NormalizedMessage.CONVERSATION_ID);
But this is giving the error - can not find any instance with conversation id 'conversationId'.
For setting the conversationId, you could do so by including the following inside your .bpel file
<bpelx:exec name="test-setConversationId" language="java" version="1.4">
<![CDATA[
setConversationId("conversationId");
]]>
</bpelx:exec>
The code:
IInstanceHandle ins = locator.lookupInstanceByConversationId(NormalizedMessage.CONVERSATION_ID);
should fetch you the required instance in this case.

Huge size file processing in PI

Hi Experts,
1. I have seen blogs which explains processing huge files. for file and sftp
SFTP Adapter - Handling Large File
File/FTP Adapter - Large File Transfer (Chunk Mode)
Here also we have constrain that we can not do any mapping. it has to be EOIO Qos.
would it be possible, to process 1 GB size file and do mapping? which hardware factor will decide that sytem is capable of processing large size with mapping?
is it number of CPUs,Applications server(JAVA and ABAP),no of server nodes,java,heap size?
if my system if able to process 10 MB file with mapping there should be something which is determining the capability.
this kind of huge size file processing will fit into some scenarios. for example,Proxy to soap scenario with 1GB size message exchange does not make sense. no idea if there is any web service will handle such huge file.
2. consider pi is able to process 50 MB size message with mapping. in order to increase the performance what are the options we have in PI
i have come across these two point many times during design phase of my project. looking for your suggestion
Thanks.

Hi Ram,
You have not mentioned what sort of Integration it is.You just mentioned as FILE.I presume it is FILE To FILE scenario.In this case in PI 711 i am able to process 100MB(more than 1Million records ) file size with mapping(File is in the delta extract in SAP ECC AL11).In the sender file adapter i have chosen recordset per message and processed the messages in bit and pieces.Please note this is not the actual standard chunk mode.The initial run of the sender adapter will load the 100MB file size into the memory and after that messages will be sent to IE based on recordset per message.If it is more than 100MB PI Java starts bouncing because of memory issues.Later we have redesigned the interface from proxy to file asyn and proxy will send the messages to PI in chunks.In a single run it will sent 5000 messages.
For PI 711 i believe we have the memory limtation of the cluster node.Each cluster node can't be more than 5GB again processing depends on the number of Java app servers and i think this is no more the limitation from PI 730 version and we can use 16GB memory as the cluser node.
this kind of huge size file processing will fit into some scenarios. for example,Proxy to soap scenario with 1GB size message exchange does not make sense. no idea if there is any web service will handle such huge file.
If i understand this i think if it is asyn communication then definitely 1GB data can sent to webservice however messages from Proxy should sent to PI in batches.May be the same idea can work for Sync communication as well however timeouts in receiver channel will be the next issue.Increasing time outs globally is not best practice however if you are on 730 or later version you can increase timeouts specific to your scenario.
To handle 50 MB file size make sure you have the additional java app servers.I don't remember exactly how many app server we have in my case to handle 100 MB file size.
Thanks

How can I execute a batch file from my java program

Hi,
Can someone help me or direct me to a link,
How can I execute a DOS batch file from my java program?
Thanks

You will need to grab a handle to the process's
outputstream so u can see its output.The OP didn't mention any output from any batch file;
nor any input for that
matter,so lets not complicate matters here for now
ok?Actually I think this is essential to see whether it works or not. It's either that or do some manual check to see whether it ran, which is not exactly elegant, and in some cases this may not be easier than simply writing the output stream code, or in fact it may be impossible to check manually.
I'm sure it wasn't intentional that your post appeared to be bristling with attitude.

Trying to compile a .java file from another .java file

Hello,
I'm trying to compile a .java file from another .java file using Runtime.exec...
String c[]=new String[3];
c[0]="cmd.exe"; c[1]="/c" ; c[2]="javac Hello.java";
Process p=Runtime.exec(c);
If anyone can help me in atleast getting the command prompt when Runtime.exec("cmd.exe") is executed...that would be great...I tried out notepad.exe, calc, explorer instead of cmd.exe...all the commands display their respective windows..except cmd.exe...the command prompt doesnt appear...
Please help me ASAP....
Thanks for your help in advance...

Implement callback for an asynchronous BPEL process through Java

Hi ,
I am trying to implement a callback functionality for an asynchronous BPEL process through java.
I found the code in the samples folder of SOA suite installation folder .
<SOA_HOME>\bpel\samples\tutorials\102.InvokingProcesses\rmi\com\otn\samples\async.
There is an AsyncInstanceWatchdog object which registers a callback object(in this case an object of AsyncCallbackImpl class) for a specific CONVERSATION_ID.
String convId = GUIDGenerator.generateGUID();
nm.setProperty(NormalizedMessage.CONVERSATION_ID, convId);
deliveryService.post(proc_name, "initiate", nm);
// register the callback
watchdog.registerAsyncCallback(convId, testAsyncHandler,
locator.getDomainAuth());
// start it
watchdog.start();
There is no problem till the last line. But once the BPEL process returns the control( does a callback), it throws the following error.
May 25, 2010 3:36:06 PM oracle.j2ee.rmi.RMIMessages EXCEPTION_ORIGINATES_FROM_THE_REMOTE_SERVER

For your reference the variable output is declared in the definition of AsyncCallbackImpl (which implements the IAsyncInstanceCallback interface).
There are 2 methods defined in the AsyncCallbackImpl class.
public void onResult(Map pResultMessage) {
System.out.println("called back! ");
Iterator iTest = pResultMessage.keySet().iterator();
while (iTest.hasNext()) {
String key = (String)iTest.next();
System.out.println(XMLHelper.elementToString((Element)pResultMessage.get(key)));
public String getVariableName() {
return "output";
The variable name is same given in the sample code. And the BPEL process returns variable named output. So the name should not be a problem.
Is it because of the scope of the variable.. If so, how do I change it.
Any help would be appreciated.

Solved it by some googling .... :)
Here is the link:-

or
[http://beautifulwaste.blogspot.com/2008/04/calling-asynchronous-bpel-process.html]
Both gives the same solution..
In pre 10.1.3.3 release the default behaviour were to keep global variable information along with the instance information for completed BPEL processes.
In 10.1.3.3 or later, this behaviour changed for performance reasons so that the default behaviour is now, not to keep any global variables for a BPEL process once the BPEL process has completed.
You can configure this behaviour on a process level basis by using the parameter keepGlobalVariables in the bpel.xml file for the specific process:
<BPELSuitcase>
<BPELProcess src=".........." id="...........">
<configurations>
<property name="keepGlobalVariables">true</property>
</configurations>
</BPELProcess>
</BPELSuitcase>

Need to track windows processes through java code.

Need to track windows processes through java code.
Eg: I want to find out whether an exe file (wrun.exe) is running or stopped.
Can I do it through java. If so can any one please tell me how to do it. That will be a great help.
Thanks,
Ramesh

There are 2 options for things like this:
1) Use Runtime.exec() to execute some command or application and parse the input from it.
2) Write some native code and use JNI to call it.
