hi,
From a form thread i got the following code to send mail with attachment with the file uploaded from the file upload ui element.
public void onActionLoadFile(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
{
//@@begin onActionLoadFile(ServerEvent)
WDWebResourceType FileType = null;
String FileName = new String();
//get attribute info for context attribute 'FileUpload'
IWDAttributeInfo attributeInfo =
wdContext.getNodeInfo().getAttribute(
IPrivateEmailView.IContextElement.FILE_UPLOAD);
//get modifiable binary type from the attribute info,requires type cast.
IWDModifiableBinaryType binaryType =
(IWDModifiableBinaryType) attributeInfo.getModifiableSimpleType();
IPrivateEmailView.IContextElement element =
wdContext.currentContextElement();
//if a file in the 'FileResource' attribute exists
if (element.getFileUpload() != null) {
try {
String mimeType = binaryType.getMimeType().toString();
byte[] file = element.getFileUpload();
//get the size of the uploaded file
element.setFileSize(this.getFileSize(file));
//get the extension of the uploaded file
element.setFileExtension(binaryType.getMimeType().getFileExtension());
//NOTE: context attribute 'FileName' must not be set
//because the FileUpload-UI-element property 'fileName'
//is bound to it. Consequently the fileName is automatically
//written to the context after file upload.
//report success message
wdComponentAPI.getMessageManager().reportMessage(
IMessageEmailComp.SF_UPLOAD,
new Object[] { binaryType.getFileName()},
false);
FileType = binaryType.getMimeType();
FileName = binaryType.getFileName();
} catch (Exception e) {
throw new WDRuntimeException(e);
}
}
//if no file in the 'FileResource' attribute exists
else {
//report error message
IWDMessageManager msgMgr = wdComponentAPI.getMessageManager();
msgMgr.reportContextAttributeMessage(
element,
attributeInfo,
IMessageEmailComp.NO_FILE,
new Object[] { "" },
true);
}
//clear the FileResource context value attribute
//element.setFileUpload(null);
String URL;
URL = this.CreateAndGetPathFileUpload(
wdContext.currentContextElement().getFileUpload(),
FileName);
// if (URL.length() == 1){
// //ERRORE
// }
wdContext.currentContextElement().setPATHFileUploaded(URL);
//@@end
}

}
When i used the same code in my application i am gett ing error in many places..
1)FileDataSource fds = new FileDataSource(<b>attach</b>);
attach cannot be resolved
2)attachmentBodyPart.setFileName(<b>FileName</b>);
fliename cannot be resolved
3)byte[] file = element.getFileUpload();
type mismatch cannot convert sting to byte[]
4)element.setFileSize(this.getFileSize(file));
method getFileSize() is undefined
5)element.setFileExtension(binaryType.getMimeType().getFileExtension());
method getFilExtension() is undefined
6)URL = this.CreateAndGetPathFileUpload(wdContext.currentContextElement().getFileUpload(),FileName);
method CreateAndGetPathFileUpload() is undefined.
7)wdContext.currentContextElement().setPATHFileUploaded(URL);
from the above error i can understand that only i have got the part of the code.
Please send me the complete coding.
some method definitions are missing....
Please help me to send the mail with attachment from the file uploaded from the file upload ui element.
Thanks in advance,
shami.
pls tell me where you get this sample code
