java - 哪个 jar 文件包含 net.opengis.wps.x100 以及如何下载它？

Question

我想在北52号开发一个wps流程，我应该使用org.n52.wps.server.AbstractSelfDescribingAlgorithm所以这个类继承自 net.opengis.wps.x100.ProcessDescriptionType 。我的问题是哪个jar文件包含这种类型，请告诉我下载这个jar文件的网址？!我的代码是:

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;
}

错误是:

我建议使用 Maven 管理的项目。创建此类项目所需的所有工件都位于公共(public) 52north maven 存储库中(包括您提到的 XML 绑定(bind)库)。以下 pom.xml 应该可以很好地作为项目框架。它已经包含了前面提到的 Maven 存储库。

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

一般来说，maven 管理的开源项目的工件应该可以在专用或中央存储库上访问。否则项目build设置将无法得到满足。因此，一般建议是首先对项目结构进行一些调查。
