which jar file contain net.opengis.wps.x100 and how can I download it?

Question

I want to develope a wps process by 52 north and I shoud use org.n52.wps.server.AbstractSelfDescribingAlgorithm so this class is inherit from net.opengis.wps.x100.ProcessDescriptionType. My question is that which jar file contain this type and please tell me the url for download this jar file?! My code is:

package www.gise.cse.iitb.ac.in;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import org.n52.wps.io.data.IData;
import org.n52.wps.io.data.binding.literal.LiteralDoubleBinding;
import org.n52.wps.server.AbstractSelfDescribingAlgorithm;

public class AddNumbersAlgo extends org.n52.wps.server.AbstractSelfDescribingAlgorithm {

@Override
public Class getInputDataType(String arg0) {
    // TODO Auto-generated method stub
    if (arg0.equals("Num1")){
        //return GTVectorDataBinding.class;
        return LiteralDoubleBinding.class;
    }
    if (arg0.equals("Num2")){
        //return GTVectorDataBinding.class;
        return LiteralDoubleBinding.class;
    }
    throw new RuntimeException("Error: WrongIdentifier");
}

@Override
public Class getOutputDataType(String arg0) {
    // TODO Auto-generated method stub
    if(arg0.equals("AdditionResult")){
        return LiteralDoubleBinding.class;
    }
    throw new RuntimeException("Error: Wrong identifier");
}
@Override
public Map<String, IData> run(Map<String, List<IData>> arg0) {

    if (arg0 == null || !arg0.containsKey("Num1")){
        throw new RuntimeException("Error: While allocating Input Parameters");
    }
    if (arg0 == null || !arg0.containsKey("Num2")){
        throw new RuntimeException("Error: While allocating Input Parameters");
    }
    List<IData> datalist = arg0.get("Num1");
    if(datalist == null || datalist.size()!=1){
        throw new RuntimeException("Error:While allocating Input Parameters");
    }

    //Checking for correctness of input
    List<IData> datalist1 = arg0.get("Num2");
    if(datalist1 == null || datalist1.size()!=1){
        throw new RuntimeException("Error:While allocating Input Parameters");
    }
    //Extracting input
            IData Num1 = datalist.get(0);
            double firstNum = ((LiteralDoubleBinding)Num1).getPayload();
            System.out.println(Num1);
            System.out.println(firstNum);

            IData Num2 = datalist1.get(0);
            double secondNum = ((LiteralDoubleBinding)Num2).getPayload();
            System.out.println(Num2);
            System.out.println(secondNum);

            double Result = firstNum + secondNum;
            //double AdditionResult;
            //create the response. In this case a GenericFileDataBinding is used (see this.getOutputDataType(...)
            IData AdditionResult = new LiteralDoubleBinding(Result);

            //new Map created
            Map<String, IData> resultMap = new HashMap<String, IData>();
            //created response added to corresponding identifier (see this.getOutputIdentifiers())
            resultMap.put("AdditionResult", AdditionResult);

            return resultMap;
}

@Override
public List<String> getInputIdentifiers() {
    // TODO Auto-generated method stub
    List<String> identifiers = new ArrayList<String>();
    identifiers.add("Num1");
    identifiers.add("Num2");
    return identifiers;
}

@Override
public List<String> getOutputIdentifiers() {
    // TODO Auto-generated method stub
    List<String> identifiers = new ArrayList<String>();
    identifiers.add("AdditionResult");
    return identifiers;
}

and error is:

Answer 1

It is hard to find any jars containing what you are searching for.

I found a subversion repository with the files in it. So I

• Checked-out the code from http://geoengine.googlecode.com/svn/trunk/references/wps/
• Ran mvn package

Now you have the jar file:

target/wps-1.0.0.jar

It is not optimal that you'll have to build it yourself but it solves the problem.

Your code may depend on other jar files as well but I guess that those are in the same repo.

I would recommend using a maven-managed project. All required artifacts to create such a project are on the public 52north maven repository (including the XML bindings library you mentioned). The following pom.xml should serve well as a project skeleton. It already has the aforementioned maven repository included.

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

        </dependency>
    </dependencies>

            <url>http://52north.org/maven/repo/releases/</url>
        </repository>
    </repositories>
</project>

In general, artifacts of a maven-managed open source project should be accessible on a dedicated or central repository. Otherwise the projects build setup would not be satisfied. So, a general advice would be to first do some investigation on the project structure.
