I am facing an odd issue in some of environments of UAT and PROD, but not in SIT. It seems to be a configuration related issue to me. Though all the settings, configuration verified are same.
Getting 'Closed Statement: next' SQLException while trying to loop over a result set with a while (rs.next()).
Code snippet, error stack trace, version details are provided below.
Existing code:
import org.apache.lucene.index.IndexWriter;
#SuppressWarnings("deprecation")
#Transactional(propagation = Propagation.REQUIRED)
private boolean fetchAndInsertData(final String indexType, final IndexWriter indexWriter) throws Exception {
logger.info("Entering fetchAndInsertData()");
Transaction tx = null;
boolean success = false;
CallableStatement callstmt = null;
ResultSet rs = null;
try {
tx = this.getCurrentSession().beginTransaction();
callstmt = this.getCurrentSession().connection().prepareCall("{call GET_VAL_PROC(?,?)}");
callstmt.setString(1, indexType);
callstmt.registerOutParameter(2, OracleTypes.CURSOR);
callstmt.execute();
rs = (ResultSet) callstmt.getObject(2);
rs.setFetchSize(5000);
logger.info("Resultset:"+ rs);
while (rs.next()) {
indexWriter.addDocument(convertResultToDoc(rs));
}
success = true;
} catch(SQLException e){
logger.error("Error in SQL execute", e);
success = false;
tx.commit();
return success;
} catch (final Exception e) {
logger.error("Getting Exception", e);
success = false;
} finally {
tx.commit();
}
logger.info("Exiting fetchAndInsertData()");
return success;
}
private Document convertResultToDoc(ResultSet results) throws SQLException {
final Document doc = new Document();
final String resultKey = results.getString(1) != null ? results.getString(1).toString() : null;
final String resultValue = results.getString(2) != null ? results.getString(2).toString() : null;
doc.add(new TextField("resultKey", resultKey, Field.Store.YES));
doc.add(new TextField("resultValue", resultValue, Field.Store.YES));
return doc;
}

private Currency curr;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public Currency getCurr() {
return curr;
}
public void setCurr(Currency curr) {
this.curr = curr;
}
}
when in make POST request to my service with data
{"title":"my title","curr":"INR"}
i get response as
{
"id": "56b0aa010364310e094c5f30",

}
but when i make GET i get error

The Currency type is currently not supported out of the box by the Spring Data MongoDB object mapping system. You can teach Spring Data MongoDB how to convert instances of that type by providing a custom implementation of a core Spring Converter as described in the reference documentation.
public class CustomMongoConfiguration extends AbstractMongoConfiguration {
#Bean
#Override
public CustomConversions customConversions() {
Converter<Currency, String> currencyToString = source -> source.toString();
Converter<String, Currency> stringToCurrency = source -> Currency.getInstance(source);
return new CustomConversions(Arrays.asList(currencyToString, stringToCurrency));
}
}
As the conversion to a String seems to be straight-forward, I create a ticket to be resolved in the upcoming version of Spring Data MongoDB.
Just in case someone else runs into #oliver-gierke's answer and get the NullPointerException like #kaluva
Spring's type resolver seems to have problems with the Lambda expression. Just change the bean definition to:
#Bean
public CustomConversions customConversions() {
Converter<Currency, String> currencyToString = new Converter<Currency, String>() {
#Override
public String convert(Currency currency) {
return currency.toString();
}
};
Converter<String, Currency> stringToCurrency = new Converter<String, Currency>() {
#Override
public Currency convert(String s) {
return Currency.getInstance(s);
}
};
return new CustomConversions(Arrays.asList(currencyToString, stringToCurrency));
}
(I'm sorry I could not add this answer as comment to Oliver's answer. Stackoverflow won't let me.)
Here's the code I'm working with:
title = request.getParameter("title");
author = request.getParameter("author");
search(title, author);
ArrayList<Book>books = new ArrayList();
while(conn.rs.next()){
Book book = new Book(conn.rs.getString(1), conn.rs.getString(2), conn.rs.getString(3));
books.add(book);
}
System.out.println(books.size());
for(int i = 0; i < books.size(); i++){
System.out.println(books.get(i).getBookID());
}
request.setAttribute("Book", books);
RequestDispatcher rd = request.getRequestDispatcher("/jspSearch.jsp");
rd.include(request, response);
JSP:
<c:forEach var="Book" items="${Book}">
<tr>
<td>${Book.bookID}</td>
<td>${Book.title}</td>
<td>${Book.author}</td>
</tr>
</c:forEach>
I am getting a numberFormatException on
rd.forward(request, response);
and
processRequest(request, response);
but I'm not doing anything with parsing a string to a number? I've been stuck on this for most of the day and I'm not doing anything with numbers so

I created a class that gets an instance of a Database connection. However I am getting an error saying the calling class is null. I will post my error below.
Now I have a working and non working version of this code. I first just jammed everything into a single class to get it up and running then started to clean it up which is when I ran into issues.
This class "createJobTicket" calls the instance of DataBaseConnectionDAO

You can notice that the following is commented out:
//private java.sql.Connection conn = null;
//private java.sql.Statement stmt = null;
This is because if I my IDE said:
Cannot make a static reference to the non-static field conn
Cannot make a static reference to the non-static field stmt
My DataBaseConnectionDAO looks like the following:
public class DataBaseConnectionDAO {
#Inject
private static Environment env;
private static DataBaseConnectionDAO instance;
// Step 1: JDBC props
String DB_URL = env.getProperty("spring.datasource.url");
String USER = env.getProperty("spring.datasource.username");
String PASS = env.getProperty("spring.datasource.password");
java.sql.Connection conn = null;
java.sql.Statement stmt = null;
private DataBaseConnectionDAO() { }
public static DataBaseConnectionDAO getInstance() {

}
}
return instance;

You need to start by understanding what this error message means:
java.lang.NoClassDefFoundError: Could not initialize class com.htd.web.rest.util.createJobTicket
When the JVM loads a class, it will complete any static initialization for that class, i.e. assign any values given to static fields and run any static { ... } blocks. As this involves running Java code, this process may cause an exception to be thrown. If an exception is thrown during a class's static initialization, the class loading will fail. Java will wrap the exception in an ExceptionInInitializerError and throw that. If you make a second attempt to load the same class, Java will flatly refuse to load it, and instead throw a NoClassDefFoundError with message Could not initialize class ....
As this is the error you are seeing, I can only conclude that your createJobTicket class is failing its static initialization, and that the exception stacktrace above is not from the first time you attempt to use the createJobTicket class. If, for example, your application is a web application, try restarting the web application container, trying again and seeing if you get a different error first time around.
The static initialization for your createJobTicket class is the following line:
private static DataBaseConnectionDAO databaseConnection = DataBaseConnectionDAO.getInstance();
So your DataBaseConnectionDAO.getInstance() method must be throwing an exception.
The best way to avoid static initialization issues like this is to avoid static initialization altogether. For example, in the following, we create a method getDatabaseConnection() which sets the databaseConnection field if it hasn't already been set, and additionally calls the DAO to return a JDBC Connection object:
private static DataBaseConnectionDAO databaseConnection;
private static java.sql.Connection getDatabaseConnection() {
if (databaseConnection == null) {
databaseConnection = DataBaseConnectionDAO.getInstance();
}
return databaseConnection.getConnection();
}
public static HSSFWorkbook getWorkbook(HSSFWorkbook workbook, Long id, Environment env){
try{
java.sql.Connection conn = getDatabaseConnection();
// ...
This approach should stop your createJobTicket class from failing to complete static initialization. However, please do not expect your code to immediately start working after doing this. The change above goes no way to fix the exception that causes the static initialization to fail. All it does is to make sure this exception only gets thrown after the class has been statically initialized. If you then attempt to run your code, you should hopefully see the actual exception in your log, instead of the NoClassDefFoundError.
So, why would your DataBaseConnectionDAO.getInstance() method be throwing an exception? My best guess is this:
#Inject
private static Environment env;
A few searches suggest that you can't use Spring to inject values into static fields like this, so perhaps you are getting a NullPointerException trying to look up values in an environment that is null. However, I haven't looked into this fully so I don't guarantee that this actually is the problem.

Now, I want to add in my code a TRY/CATCH block when I call this operation:
QueryExecution qe = query(string);
What does condition I must insert in catch for this error?
From your code it looks like it throws HttpException.
so write:
try
{
QueryExecution qe = query(string);
}
catch (HttpException ex)
{
System.out.println (ex.getMessage()); //Optional
ex.printStackTrace(); //Optional
}
Another catch can be catch (Exception ex) {..} // that will catch any problem. BUT if you know the exact exception use the exact.
At the catch i wrote the common error prints, but you can fill that as you find it suits your problem.
