Re: xmlsec-c question about XSECEnv
In an ideal world you shouldn't have to touch XSECEnv at all. The idea is a way to pass information between the various library components about a particular piece of XML. As an example, the XENCCipher class "owns" an instance of XSECEnv. It then passes it to all the other XENC classes that it uses to actually build an encrypted (or decrypted) piecce of XML. So the class is created per XML instance - but all the objects that exist around that instance should have pointers to that single instance. My read of below is that you are lifting bits of code from the library to use in your own stuff rather than actually calling the library through the API? XSECEnv is supposed to be hidden from normal use, so I'd be concerned if there is somewhere you have to manipulate it for normal use of the library. Cheers, Berin Scott Cantor wrote: I'm starting to incoporate a few pieces of the XML Encryption classes into some of my project, and I had a question about the XSECEnv class, specifically about the DOMDocument parameter in the c'tor, and how to use this class. Is this object supposed to be created per XML instance being manipulated? It seems like more of a global settings object that would be static and common across the library. I looked at the code, and I can see that right now there wouldn't be much harm if I passed NULL in, but obviously I can't depend on that behavior. -- Scott
Apache XML Security 1.2 for Java
Hello,
Recently I tried to upgrade my project to use new Apache XML Security 1.2 for
Java
and found that now the library does c14n much MUCH more slowly than it was with
1.1.
Here is a simple test:
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.apache.commons.lang.time.StopWatch;
import org.apache.xml.security.c14n.Canonicalizer;
import org.w3c.dom.Document;
import org.xml.sax.InputSource;
public class Test {
private final static int REPEAT = 1000;
private StopWatch timer = new StopWatch();
private Canonicalizer canon =
Canonicalizer.getInstance(Canonicalizer.ALGO_ID_C14N_OMIT_COMMENTS);
private Document document;
public Test(String file) throws Exception {
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(true);
factory.setValidating(false);
DocumentBuilder builder = factory.newDocumentBuilder();
document = builder.parse(new InputSource(file));
}
public void runTest() throws Exception {
timer.start();
for (int i = 0; i < REPEAT; i++) {
canon.canonicalizeSubtree(document);
}
timer.stop();
System.out.println("time spent " + String.valueOf(timer.getTime()) + " ms");
}
public static void main(String[] args) throws Exception {
org.apache.xml.security.Init.init();
Test test = new Test(args[0]);
test.runTest();
}
}
Just drop commons-lang-2.0.jar, commons-logging.jar, xercesImpl.jar,
xml-apis.jar and xmlsec.jarto the
classpath and run java Test File.xml.
Version 1.1 output: time spent 952 ms
Version 1.2 output: time spent 29172 ms
Where is the catch?

Can you please post your test.xml as well?
thanks,
