Hi all,
I'm using a Resource Link with a WebResource to show a PDF Document in the
browser. This works fine for Websphere 6.1.0.2 on Windows 2003 Server but
fails on WebSphere 6.1.0.2 on Solaris:

The code in Wicket:
WebResource pdfSignatureDocument = new WebResource() {
private static final long serialVersionUID = 1L;
@Override
protected void setHeaders(WebResponse response) {
super.setHeaders(response);
response.setAttachmentHeader(
"signature.pdf");
}
@Override
public IResourceStream getResourceStream() {
log.debug("Printing mandate PDF for
mandate"
+ selectedMandate
.getReference());
ArrayList<Serializable> list = new
ArrayList<Serializable>();
list.add(selectedMandate);
MmgReportManager rm = new
MmgReportManager();
File pdfMandate = null;
try {
pdfMandate =
rm.exportReportAsFile(ReportTypes.SELECTED_MANDATE, list,
SupportedFileTypes.PDF);
} catch (PtsException e) {
log.error(e);
error(e);
}
log.debug("returning fileResource ...");
return new FileResourceStream(pdfMandate);
}
};
pdfSignatureDocument.setCacheable(false);
add(createPDFSignatureDocumentLink = new
ResourceLink<WebResource>("createPDFSignatureDocument",
pdfSignatureDocument));
