AXIS signature

["t. winkler" <t....@sdz-medien.de>]

Hello once again,

O.k., I tried again and again but it won't work. I now took the original source code by the book of Torsten Langner that even includes Christian Geuer-Pollmans keystore and I also guess the rest of his code somehow a little bit altered (I included the complete Sourcecode for you all)

Here's the error message I received:
C:\webservices\webapps\axis\WEB-INF\classes>java wsumsatz/Client

Please help me Obi-Wan Kenobi :-) I'm not getting it (remember I'm new to all of this! Two months ago I didn't even know how to do a web service!)

Best regards,
Yours
Tobias Winkler

PS: I had to change JavaUtils.... to Messages in two classes and the javax.... rpc.Qname seems to be wrong in the classes in these files!

Feel free to contact me at Tobias.B.Winkler@t-online.de the next few days, too, because I'm not at my working environment due to 2 days at the University of Co-operative Education I'm attending!

PPS: I think the certificate thing does not function, but that's just my guess! Maybe???

Add a print statement in SignedSOAPEnvelope after you get the certificate:

X509Certificate cert = (X509Certificate) 
ks.getCertificate(certificateAlias);
System.out.println("SignedSOAPEnvelope.cert = " + cert);

What's printed out there?
