哪個jar文件包含org.n52.wps.server.observerpattern.ISubject，我該如何下載它？

Question

IM想寫一個.java文件，並將其導入52north WPS服務，但我的代碼是這樣的代碼

package org.n52.wps.demo; 

import java.util.ArrayList; 
import java.util.List; 
import java.util.Map; 

import org.geotools.feature.FeatureCollection; 
import org.geotools.feature.FeatureIterator; 
import org.geotools.geometry.iso.topograph2D.Coordinate; 
import org.geotools.geometry.jts.CoordinateSequenceTransformer; 
import org.n52.wps.server.AbstractSelfDescribingAlgorithm; 
import org.n52.wps.io.data.IData; 
import org.n52.wps.io.data.binding.complex.GTVectorDataBinding; 


import net.opengis.wps.x100.ProcessDescriptionType; 
public class ConvexHullDemo extends AbstractSelfDescribingAlgorithm { 

@Override 
public Class<?> getInputDataType(String identifier) { 
    if (identifier.equalsIgnoreCase("FEATURES")) { 
     return GTVectorDataBinding.class; 
    } 
} 

@Override 
public Class<?> getOutputDataType(String identifier) { 
    if (identifier.equalsIgnoreCase("FEATURE")) { 
     return GTVectorDataBinding.class; 
    } 
} 

@Override 
public List<String> getInputIdentifiers() { 
    List<String> list=new ArrayList<String>(); 
    list.add("FEATURES"); 
    return list; 
} 

@Override 
public List<String> getOutputIdentifiers() { 
    List<String> list=new ArrayList<String>(); 
    list.add("polygon"); 
    return list; 
} 

@Override 
public Map<String, IData> run(Map<String, List<IData>> inputData) { 

    if (inputData == null || !inputData.containsKey("FEATURES")) { 
     throw new RuntimeException("Error while allocating input parameters"); 
} 

List<IData> dataList = inputData.get("FEATURES"); 

if (dataList == null || dataList.size() != 1) { 
     throw new RuntimeException("Error while allocating input parameters"); 
} 

IData firstInputData = dataList.get(0); 
FeatureCollection featureCollection = ((GTVectorDataBinding) firstInputData).getPayload(); 
} 

FeatureIterator iter = featureCollection. 
List<Coordinate> coordinateList = new ArrayList<Coordinate>(); 
int counter = 0; 
Geometry unifiedGeometry = null; 
while (iter.hasNext()) { 
       SimpleFeature feature = (SimpleFeature) iter.next(); 
       if (feature.getDefaultGeometry() == null) { 
         throw new NullPointerException("defaultGeometry is null in feature id: "+ feature.getID()); 
       } 
       Geometry geom = (Geometry) feature.getDefaultGeometry(); 
       Coordinate[] coordinateArray = geom.getCoordinates(); 
       for(Coordinate coordinate : coordinateArray){ 
         coordinateList.add(coordinate); 
       } 
} 

} 

和全教程：Custom 52north WPS by java Process。

但這種錯誤出現了：

多個標記在該行

• 類型ConvexHullDemo的層次結構是不一致的

• 類型org.n52.wps.server .observerpattern.ISubject無法解析。它是間接需要的.class文件

引用其中的jar包含此org.n52.wps.server.observerpattern.ISubject，我怎麼能立即下載呢？

你可能想發佈您的問題之前閱讀多一點點，因爲我發現你鏈接的網站上的awnser你的問題：

它說你應該有WPS設立其在這裏解釋說： https://wiki.52north.org/bin/view/Processing/52nWebProcessingService
