java.lang.NoSuchMethodError: org/apache/http/conn/scheme/Scheme.<init>(Ljava/lang/String&

[iorch]

Hi All,

I am using sardine with spring 3 and json to create a REST Web service under eclipse IDE: this is the sample I am using to do a simple listing:

      public static List<DavResource> getListFromServer()throws IOException {

Sardine sardine = SardineFactory.begin("username","password");

List<DavResource> resources = sardine.list("http://localhost/");

for (DavResource res : resources){

System.out.println(res);

}

return filesinServer;

}

If i run this method from a main method it works, but if I use it as a library inside another eclipse project where all the WebServices are this stacktrace is thrown:

Caused by: java.lang.NoSuchMethodError: org/apache/http/conn/scheme/Scheme.<init>(Ljava/lang/String;ILorg/apache/http/conn/scheme/SchemeSocketFactory;)V

I got the problem, there is a runtime conflict between Websphere 8 libs and sardine libs for the httpclient jar. I was using (as requried by the API) the httpclient-4.1.2.jar which has a new version of the Scheme class.

The problem was that the eclipse adds a Websphere Application Server  v8.0 lib which has an older class version of the Scheme class inside one of the server jar. 

Since its not an easy task to change the serve libs, i will have to look for another approach.

Regards!!

you can just modify the sardine source code in your own branch of sardine to compile against the websphere version of the http libs. it shouldn't be too difficult to do this.

I'm getting the same exception. My question is for Jon Stevens; how to modify the sardine source code and compile against the websphere version of the http libs?
