Unable To print Context Data

[Former Member]

Hi All,

I want to Print (Hard Copy) of my context Data,ie

I want to print data on local printer .

I tried by lots of ways but i could't get succes.

one of the way is that

One blank text file is copied to projects src/mime/component

folder and write the context data to that file.then send that file to printer,reading and writing of the file is woking fine but can't get the printout.

**Used Code**

public void onActionPrintData(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )

{

//@@begin onActionPrintData(ServerEvent)

// method to print a file from the server

// a empty text file is created in src
mimes
Components
<package name>\<filename>

// the context data is written to this file in an event and then the file is directed towards the printer

try {

// creating a copy of the file on the server

File obj = new File("temp
webdynpro
web
local
TestTableEdit
Components
com.gpk.examples.testtableedit.TestTableEditApp
printData.txt");

FileWriter obj1 = new FileWriter(obj);

// looping through the context data.

obj1.write("Account Number");

obj1.write("\t");

obj1.write("Name of The Account Holder");

obj1.write("\t");

obj1.write("Available Balance");

obj1.write("\n");

for (int i = 0;i < wdContext.nodeResultAllAccountDetails().size();i++) {

obj1.write(wdContext.nodeResultAllAccountDetails().getResultAllAccountDetailsElementAt(i)

.getAccountNumber());

obj1.write("\t");

obj1.write(

wdContext

.nodeResultAllAccountDetails()

.getResultAllAccountDetailsElementAt(i)

.getName());

obj1.write("\t");

obj1.write(

wdContext.nodeResultAllAccountDetails()

.getResultAllAccountDetailsElementAt(i)

.getBalance()+ "");

obj1.write("\n");

}

obj1.close();

//reading the file

File obj5 =new File("temp
webdynpro
web
local
TestTableEdit
Components
com.gpk.examples.testtableedit.TestTableEditApp
printData.txt");

java.io.FileReader obj3 = new java.io.FileReader(obj5);

int count = (int) obj5.length();

char obj4[] = new char[count];

obj3.read(obj4);

wdContext.currentContextElement().setReadData(new String(obj4));

obj3.close();

} catch (Exception e) {

e.printStackTrace();

}

//*Printing Code*

FileInputStream psstream = null;

try {

psstream =new FileInputStream("temp
webdynpro
web
local
TestTableEdit
Components
com.gpk.examples.testtableedit.TestTableEditApp
printData.txt");

} catch (FileNotFoundException ffne) {

}

if (psstream == null) {

return;

}

DocFlavor psInFormat = DocFlavor.INPUT_STREAM.TEXT_PLAIN_HOST ;

PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();

aset.add(new Copies(1));

Doc myDoc = new SimpleDoc (psstream,psInFormat,null);

wdComponentAPI.getMessageManager().reportSuccess(myDoc.toString());

PrintService services = PrintServiceLookup.lookupDefaultPrintService();

PrintServiceLookup.lookupPrintServices(psInFormat, aset);

if (services.length > 0) {

DocPrintJob job = services.createPrintJob() ;

try {

job.print(myDoc, aset);

} catch (PrintException pe) {

}

}

//@@end

}

Its an uregent.

Plz Help me.

Thanx,

Sanjay

As far as I know printing is not supported in WebDynpro. Not sure about the new releases . However some people do it through javaScripts but won't be of much help in the further releases.

helo Sanjay,

As far as i know there is no functinality to print(on paper) through webdynpro application. the most u can do is to create a J2EE application that can print the contents from a file, as soon as it is called.

now on clicking the button to print the contents, u can call the J2EE application in the exit plug or in an external window.

Regards,

Piyush.
