I find the example in DOCS: here.
Well,in my project, the vars declarations are in .mod file only and I import them using :

IloOplRunConfiguration rc0 = oplF.createOplRunConfiguration(DATADIR
                + "/mod_v1.mod", DATADIR + "/data_v1_2.dat");//The model definition,specify the data source for the model

Now, i want to print each solutions,like:

while(cp.next()){
...
                IloOplElement K = oplModel.getElement("K");//取出解中的K值oplModel=rc0.getOplModel()
                double KNum = K.asNum();//取出解中的K值
                newK=Double.toString(KNum);//取出解中的K值
...
                System.out.println(newK);
}

The problem is: value of "newK" is always same as the first solution that cp has found.

Does anyone familiar with this problem?

I found a solution:

IloOplFactory oplF = 

new IloOplFactory();
//The model definition IloOplRunConfiguration rc0 = oplF.createOplRunConfiguration(DATADIR + 
"/mod_v1.mod", DATADIR + 
"/data_v1_2.dat");
//The model definition,specify the data source for the model IloOplModel oplModel=rc0.getOplModel();
//The model itself oplModel.generate();
//The model itself IloIntVar K = oplModel.getElement(
"K").asIntVar();
//取出解中的K值 IloIntVarMap CenInfs =oplModel.getElement(
"CenInfs").asIntVarMap();
//取出解中的CenInfs值 IloIntVarMap Compositions = oplModel.getElement(
"Compositions").asIntVarMap();
//取出解中的Compositions值  IloCP cp=rc0.getCP();
//The solver cp.startNewSearch();
//Start solving 

int solCount=0;
//计数：解的数量 

while(cp.next())
{
//找到一个解，进行输出 solCount++;
//解的数量加一 String newObj=Double.toString(cp.getObjValue());
//解对应的目标函数值 String newK=
"";
//对应决策变量K：TAZ个数（见.mod文件） List<String> newCenInfs=

new ArrayList<String>();
//对应决策变量CenInfs：TAZ中心影响区（INF）的ID（见.mod文件） Map<String,List<String>> newCompositions=

new HashMap<String,List<String>>();
//对应决策变量Compositions：TAZ组成矩阵（见.mod文件） 

double KNum =cp.getValue(K);
//取出解中的K值 newK=Double.toString(KNum);
//取出解中的K值 

for(

int i=1;i<=CenInfs.getSize();i++)
{
//取出解中的CenInfs值 

if(cp.getValue(CenInfs.get(i))==1)
{ newCenInfs.add(Integer.toString(i));
//取出解中的CenInfs值，保存被选中为中心INF的INF的Id，例如:[2,3,4,11] 
} 
} 
//取出解中的Compositions值 

for(

int i=0;i<newCenInfs.size();i++)
{;
//取出解中的Compositions值：取出第i个中心INF的TAZ的Compositions String thisCenInfIdStr=newCenInfs.get(i);
//例如：i=0,thisCenInfIdStr="2" 

int thisCenInfId=Integer.parseInt(thisCenInfIdStr);
//int型的thisCenInfIdStr List<String> CellIdsOfNewComps=

new ArrayList<String>(); 

for(

int j=1;j<=Compositions.getSub(thisCenInfId).getSize();j++)
{ 

if(cp.getValue(Compositions.getSub(thisCenInfId).get(j))==1)
{ String thisCellIdStr=Integer.toString(j); CellIdsOfNewComps.add(thisCellIdStr); 
} 
} newCompositions.put(thisCenInfIdStr,CellIdsOfNewComps); 
} Solution oneSol=

new Solution(newObj,newK,newCenInfs,newCompositions);
//根据该解的结果创建一个solution printSolution(oneSol); writeSolution_TXT(oneSol,fatFolder,Integer.toString(solCount)); fea_Sols.add(oneSol); 
}

Since your code uses OPL you are probably better off asking this question on the OPL forum. There you will find the experts to answer your question and/or discuss the solution you found.
