I am trying to query Java in Gemfire. I am able to put the data and get the regions using Java API in Gemfire. But whenever I try to query my regions, I get InternalGemfireError.
I Start my Locators and Servers in GFSH
gfsh>start locator --name=locator --log-level=DEBUG
gfsh>configure pdx --read-serialized=true
gfsh>start server --name=server1 --log-level=DEBUG
create region --name=Account --type=PARTITION
I have created a client project using Java Api to put and fetch the data
Client.java
public static void main(String[] args) throws FunctionDomainException, TypeMismatchException, NameResolutionException, QueryInvocationTargetException {
ClientCache cache = new ClientCacheFactory().set("cache-xml-file", "cacheClient.xml")
.create();
Region<Integer, Account> accountRegion = cache.getRegion("Account");
List<Account> accounts = TestData.createAccountData();
for(Account a : accounts) {
accountRegion.put(a.getAccountNumber(), a);
}
}
cacheClient.xml
<?xml version="1.0" encoding="UTF-8"?>
<client-cache

Account.java
public class Account {
public Account() {
// TODO Auto-generated constructor stub
}
private String name;
private String openDate;
private int accountNumber;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getOpenDate() {
return openDate;
}
public void setOpenDate(String openDate) {
this.openDate = openDate;
}
public int getAccountNumber() {
return accountNumber;
}
public void setAccountNumber(int accountNumber) {
this.accountNumber = accountNumber;
}
@Override
public String toString() {
return "Account [name=" + name + ", openDate=" + openDate
+ ", accountNumber=" + accountNumber + "]";
}
public Account(String name, String openDate, int accountNumber) {
super();
this.name = name;
this.openDate = openDate;
this.accountNumber = accountNumber;
}
While Querying or gettingf data, I just write
accountRegion.query("Select * from /Account");
or
Account acc = accountRegion.get(1);
And it throws me the following exception
