Hi, experts, I have to setup a project to realize pdf downloading with web dynpro. But unluckily, I have tried all the methods in this froum ,there's really strange problem .Because when I click the link of Download UI link, there's no reaction at all, I really don't know why.Below is the codes I used , can anyone help me ? thank you very much!
public void wdDoInit()
{
//@@begin wdDoInit()
IWDAttributeInfo attInfo =
wdContext
.currentContextElement()
.node()
.getNodeInfo()
.getAttribute(
"Pdfsource");
ISimpleTypeModifiable type = attInfo.getModifiableSimpleType();
IWDModifiableBinaryType binaryType = (IWDModifiableBinaryType) type;
binaryType.setFileName("test.pdf");
binaryType.setMimeType(WDWebResourceType.PDF);
try {
int length =
(int) wdContext.currentPdfdownloadElement().getBin_Filesize();
byte b[] = new byte[length];
b = wdContext.currentPdfdownloadElement().getBin_File();
wdContext.currentContextElement().setPdfsource(b);
} catch (Exception ex) {
}
"Pdfsource" is the context value attribute of type binary.And Bin_File is the xstring type parameter from my RFC contains pdf content.
I used two views and one customer-controller . I put some value in the first view to set search condition.and the second then appears and have the download UI element. Are there any additional codes I should use? pls help!
