Hello!
How can I get data from my tamino database and transform returned data by xsl stylesheet?
any help will be appreciated!
thanks in advance!
best regards,

PS.
I have been trying in the following way (but it doesn’t work)
Here is my code:
-------------------------------------
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.Transformer;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;
import java.io.*;
import com.softwareag.tamino.API.dom.TaminoClient;
import com.softwareag.tamino.API.dom.TaminoError;
import com.softwareag.tamino.API.dom.TaminoResult;
import org.w3c.dom.Element;
import org.w3c.dom.Document;
public class Example2 {
private
TaminoClient tc;
TaminoResult tr;
Document dc;
Element el;
public void main(String arg) {
Example2 example = new Example2();
int pageSize = 0;
String url = “http://localhost/tamino/mydb/col”;
try {
tc = new TaminoClient(url);
tc.setPageSize(pageSize);
tc.startSession();
tr = tc.query(“doc”);
Element el = tr.getElement();
String ls_xsl = “C:\data\doc.xsl”;
StreamSource xsl = new StreamSource(new File(ls_xsl));
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer(xsl);
transformer.transform(el, System.out);
tc.endSession();
}
catch (com.softwareag.tamino.API.dom.TaminoError error) {
System.out.println(error.getMessage());
}
}
}
-------------------------------------
I got the following error text:
–
Example2.java:39 transform(javax.xml.transform.Source, javax.xml.transform.Result) in javax.xml.transform.Transformer cannot be applied to (org.w3c.dom.Element, java.io.PrintStream)
transformer.transform(el, System.out)
^
1 error

How should I fix my sample code? Please help, thanks a lot!
You won’t be able to use the HTTP client API with JAXP for transformation purposes because JAXP expects DOM level 2 support and the HTTP client API only delivers DOM level 1 objects.
The transform() method takes two parameters which are Source and Result interfaces respectively. You can create a DOMSource element for example using a DOM tree. For the Result you could use StreamResult.

First of all, thanks for a quick reply, Stuart. 
I still have been trying to get it working but I have got some problems.
However, I found some ideas in the following posts:
1)
http://tamino.forums.softwareag.com/viewtopic.php?p=14489)
http://tamino.forums.softwareag.com/viewtopic.php?p=10948
Finally, now my code like this:
–
<%@ page
import = “org.w3c.dom.,
javax.xml.transform.,
com.softwareag.tamino.API.dom2.,
java.util.,
java.io.*,
javax.xml.transform.stream.StreamSource,
javax.xml.transform.stream.StreamResult”
%>
<%
try {
TaminoClient tc = new TaminoClient(“http://localhost/tamino/mydb/col”);
tc.setPageSize(0);
TaminoResult tr = tc.query(“doc”);
Element el = tr.getElement();
TransformerFactory tFactory = TransformerFactory.newInstance();
String ls_xsl = “C:\data\data.xsl”;
StreamSource xsl = new StreamSource(new File(ls_xsl));
Transformer transformer = tFactory.newTransformer(xsl);
StreamResult result = new StreamResult(out);
transformer.transform(new javax.xml.transform.dom.DOMSource(el), result);
}
catch (Exception e)
{
e.printStackTrace();
}
%>

It is the Example2.jsp page.
Unfortunately, it does NOT transform returned data form tamino. IE shows only plain text (but it should be a pretty table). 
What is the problem?
Please give some ideas?
How can I fix this code?
in advance, thanks a lot!

Hi Dariusz,
One possible reason that the results are not formatted as expected is that you are not transforming the whole document, but instead only transforming a fragment that the stylesheet processes with the default templates. So maybe change the following line:
transformer.transform(new javax.xml.transform.dom.DOMSource(el), result);
to:
transformer.transform(new javax.xml.transform.dom.DOMSource(el.getOwnerDocument()), result);
Please note that the DomApiClient3.zip is not officially supported; the preferred API to use is the TaminoAPI4J which can be used with JAXP.
Hope this helps,

yes, now it works.
table showed in ie.
thanks Stuart!
However, I made some modification in my code, and I found that previous code can be written in simpler way.
–
Element el = tr.getElement();
Document d1 = el.getOwnerDocument();
–
to:
–
Document d2 = tr.getDocument();
–
Two lines was changed into one line (code is simpler, of course).
Unfortunately, combination getDocument() and getOwnerDocument() only in Document type is not work. Can you tell me why?
–
Document d2 = tr.getDocument();
Document d3 = d2.getOwnerDocument();
–
thanks for help.

Here is the whole changed code.

StreamResult result = new StreamResult(out);
// transformer.transform(new javax.xml.transform.dom.DOMSource(d1), result);

transformer.transform(new javax.xml.transform.dom.DOMSource(d3), result);

I guess this doesn’t work (I’ve not checked it though) because the Document object is the owner document and therefore it doesn’t make sense to ask for the owner document of a document. getOwnerDocument() is really useful to get access to the Document object from any Node object. So your line of:
Document d3 = d2.getOwnerDocument();
</pre><BR><BR>can simply be rewritten to:<BR><BR><pre class="ip-ubbcode-code-pre">
Document d3 = d2;
