I am currently trying to incorporate a web service into my application. I do not have access to the web service itself but is accessed through a jar file. Below is the code which accesses the web service:
import java.util.List;
import java.io.Serializable;
import java.lang.String;
import com.zf.fileviewing.connection.FVConnectData;
import com.zf.fileviewing.connection.FVConnector;
import java.net.URL;
public class CheckOutAxalant implements Serializable
{
private static final long serialVersionUID = 1L;
public List<String> CheckoutAxalant(String docCid)
{
List<String> fileNames;
String userId="";
FVConnectData fvData = new FVConnectData();
fvData.setWsKeyword("");
fvData.setWsUrl("");
FVConnector con = new FVConnector(fvData);
// get all filenames of document
try
{
fileNames = con.getAllFileNames(docCid, userId);
for (String value : fileNames)
{
System.out.println("filename: " + value);
}
return fileNames;
}
catch (Exception e)
{
System.out.println("ERROR: " + e.getMessage());
e.printStackTrace();
return null;
}
}
The error occurs on the line:
FVConnectData fvData = new FVConnectData();
The full stack trace is as follows:

I am extremely stuck on this as I am unable to access the web service.
Also FYI, If I ran the same code but adapt it into a normal Java Application it works no problem.
This is a classloader issue: NoClassDefFoundError: com/zf/fileviewing/connection/FVConnectData.
Are you sure all the dependencies are present in the application you deploy? Look first at the import in FVConnectData.
EDIT :
To the JAR file you use for the webservice call, use the mvn install:install-file goal. It will install the artifact in your local repository and make it available to MAven. You can then add it to your pom.xml in the dependencies section (provide the groupdId, artifactId and version).
You can verify that it has been added to the dependencies of your project by calling mvn dependency:tree.
