Hi,
I had to deal with something similar (not exactly the same problem) and
I think you could do the following:
1-Mount a bookmarkable page
(mountBookmarkablePage("/mypdf",MyPdfPage.class));
2-On my MyPdfPage.hmtl have a markup
<div style="padding: 15px 5px 5px 5px;">
<div><span wicket:id="message"></span></div>
<iframe wicket:id="iframe" src="xxx.html" width="98%" height="400"
align="center">
Your browser doesn't support iframes
</iframe>
</div>
3- MyPdfPage.java you have something similar to (this just a sketch):
import java.util.HashMap;
import org.apache.wicket.Resource;
import org.apache.wicket.ResourceReference;
import org.apache.wicket.markup.html.WebPage;
import org.apache.wicket.markup.html.basic.Label;
import com.abbott.aeres.core.web.button.BaseDocumentResource;
import com.abbott.aeres.core.web.button.FinalDocumentResource;
import com.isencia.sherpa.web.resource.ResourceInlineFrame;
public class MyPdfPage extends WebPage {
public MyPdfPage() {
final ResourceReference reference = new
ResourceReference("myPdfDocument.pdf");
HashMap<String, String> params = new HashMap<String, String>();
final boolean haveAdocument = haveADocument();// check if I have
a document
String docId = "xxx";
params.put(MyDocumentResource.ID, docId);
final String finalId = docId;
Label message = new Label("message", "Don't have a PDF, sorry!") {
private static final long serialVersionUID = 1L;
@Override
public boolean isVisible() {
return !haveAdocument;
}
};
new ResourceInlineFrame(this, "iframe", reference, params) {
private static final long serialVersionUID = 1L;
@Override
public boolean isVisible() {
return haveAdocument;
}
};
}
}
3-final ResourceReference reference = new
ResourceReference("myPdfDocument.pdf"); makes reference to a dynamic
resource reference you mount at application level as
getSharedResources().add("myPdfDocument.pdf", new MyDocumentResource());
it is important that it ends in ".pdf" otherwise IE will refuse to open
it in an iframe (if someone knows a better way please tell me about;-).
MyDocumentResource is a class extending DynamicWebResource that
generates the PDF based on some params (see above). Make sure you
overide the setHeaders
method and put the response.setHeader("Content-Disposition", "inline;
filename=\"" + name + "\""); otherwise IE will not open it in the iframe
4-The listing of ResourceInlineFrame is:
public class ResourceInlineFrame extends WebMarkupContainer
{
private static final long serialVersionUID = 1L;
private ResourceReference reference;
private HashMap<String, String> params;
public ResourceInlineFrame(MarkupContainer parent, final String id,
ResourceReference reference)
{
this(parent, id, reference, null);
}
public ResourceInlineFrame(MarkupContainer parent, final String id,
ResourceReference reference, HashMap<String, String> params)
{
super(parent, id);
if(reference == null)
{
throw new IllegalArgumentException("Invalid Resource
Reference");
}
this.reference = reference;
this.params = params;
}
protected CharSequence getURL()
{
StringBuffer url = new StringBuffer();
url.append(urlFor(reference));
if(params != null && !params.isEmpty()) {
url.append("?");
Iterator<String> it = params.keySet().iterator();
while(it.hasNext()) {
String key = it.next();
url.append(key);
url.append("=");
url.append(params.get(key));
if(it.hasNext())
url.append("&");
}
}
return url;
}
@Override
protected final void onComponentTag(final ComponentTag tag)
{
checkComponentTag(tag, "iframe");
// Set href to link to this frame's frameRequested method
CharSequence url = getURL();
// generate the src attribute
tag.put("src", Strings.replaceAll(url, "&", "&"));
super.onComponentTag(tag);
}
public HashMap<String, String> getParams() {
return params;
}
public void setParams(HashMap<String, String> params) {
this.params = params;
}
}
Hope this is of some help...
