Saving excel file

Question

Hi,
    I am able to export all table data into excel file with the help of tutorial "Exporting Context Data into
Excel Using the Web Dynpro Binary Cache".
     But instead of the process described in the tutorial i want to save the file directly and send it as attachment.
     If anybody knows it please help me its urgent.
        Thanks and regards

Hi,
You can do something like this:
From the navigator view in NWDS, create a new file, say "TableData.csv" under src/mimes/Components/<your component>/TableData.csv.
Say your context looks like this:
-Root
--Texts(value node, datasource for your table)
---Msg(value attribute, bound to 1st column of table)
---Msg2(value attribute, bound to 2nd column of table)
In the event handler for send button, use a code like this:
String path = null;
try {
path = WDURLGenerator.getResourcePath(
wdComponentAPI.getDeployableObjectPart(),
"TableData.csv");
} catch (WDAliasResolvingException e2) {
// TODO Auto-generated catch block
e2.printStackTrace();
try {
FileWriter f = new FileWriter(path);
BufferedWriter b = new BufferedWriter(f);
IWDNode tableNode = wdContext.nodeTexts();
for(int i = 0; i < tableNode.size(); i++){
IWDNodeElement currElem = tableNode.getElementAt(i);
b.write(currElem.getAttributeValue("Msg").toString());
b.write(",");
b.write(currElem.getAttributeValue("Msg2").toString());
b.write(",");
b.newLine();     
b.close();
} catch (IOException e) {
// TODO Auto-generated catch block
wdComponentAPI.getMessageManager().reportException(e.getMessage(),true);
See your other thread.
