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 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;

When I use post method everything is fine, but CommonsMultipartResolver don't want to work with PUT or PATH methods.
There is stack trace

Configuration:
#Bean
public CommonsMultipartResolver multipartResolver() {
CommonsMultipartResolver resolver=new CommonsMultipartResolver();
resolver.setDefaultEncoding("utf-8");
return resolver;
}
Controller code:
#RequestMapping(method = RequestMethod.POST)
public void addQuestion(#RequestParam MultipartFile script,
#RequestParam MultipartFile answerTemplate,
#RequestParam DataSourceType dataSourceType,
#RequestParam DataType dataType,
#RequestParam ScriptType scriptType,
#RequestParam List<Tag> tags,
#RequestParam(required = false) String dataSourceResource){
Question question = new Question(tags, dataSourceType, dataSourceResource, dataType, scriptType);
questionHelper.saveQuestion(question, script, answerTemplate);
}
#RequestMapping(value = "/{id}", method = RequestMethod.PUT)
public void updateQuestion(#PathVariable Integer id,
#RequestParam(required = false) MultipartFile script,
#RequestParam(required = false) MultipartFile answerTemplate,
#RequestParam(required = false) DataSourceType dataSourceType,
#RequestParam(required = false) DataType dataType,
#RequestParam(required = false) ScriptType scriptType,
#RequestParam(required = false) List<Tag> tags,
#RequestParam(required = false) String dataSourceResource){
Question question = new Question(tags, dataSourceType, dataSourceResource, dataType, scriptType);
questionHelper.updateQuestion(id, question, script, answerTemplate);
}
The answer is that CommonsMultipartResolver support only POST. It can work with other methods but when it checks if request is multipart it checks method and only POST allowed. The solution is extends this resolver and override method that checks to allow other http methods.
In your configuration try to change the bean method to:
#Bean("multipartResolver")
public CommonsMultipartResolver multipartResolver(){
I am trying to parse a simple json string into a map and am trying to use the Jackson library to do so. Here's my code so far:
private static Map<String, String> handleJsonResponse(OAuthResourceResponse response) {
JsonFactory factory = new JsonFactory();
ObjectMapper mapper = new ObjectMapper();
TypeFactory typeFactory = mapper.getTypeFactory();
MapType mapType = typeFactory.constructMapType(HashMap.class, String.class, String.class);
Map<String, String> result;
JsonParser parser = factory.createParser(response.getBody());
result = mapper.readValues(parser, mapType);
}
However, I'm getting an error saying:
I've tried doing this:
result = mapper.readValues(parser, new TypeReference<Map<String, String>>() {});
But I get the same result as above.
Finally, I've tried doing this:
result = (Map) mapper.readValues(parser, mapType);
But then I get a runtime error of:
java.lang.RuntimeException: com.fasterxml.jackson.databind.MappingIterator cannot be cast to java.util.Map

Any idea what I'm doing wrong?
I solved it by just using Spring Boot's native json parser:
org.springframework.boot.json.JsonParser springParser = JsonParserFactory.getJsonParser();
Map<String, Object> result = springParser.parseMap(response.getBody());
However the real credit goes to ericbn from this post: How to parse a dynamic JSON key in a Nested JSON result?
I keep getting an Exception for the below code:
org.springframework.integration.MessageDispatchingException: Dispatcher has no subscribers
#Bean
public MessageChannel topicChannel(){
return new DirectChannel();
}
#Bean
public ActiveMQQueue requestQueue() {
return new ActiveMQQueue("queue.demo");
}
#Bean
public ActiveMQConnectionFactory ConnectionFactory() {
ActiveMQConnectionFactory factory = new ActiveMQConnectionFactory();
factory.setBrokerURL("tcp://localhost:61616");
return factory;
}
#Bean
public IntegrationFlow outboundFlow() {
return IntegrationFlows
.from(topicChannel())
.handle(Jms.outboundAdapter(ConnectionFactory()).destination(
requestQueue())).get();
}
Can any one help on this

i saw many SO posts like : THIS and THIS and THIS but no solution for me
can some one help ?
You start by writing a response by yourself, and then return the name of the view, and thus telling Spring that it should generate an HTML page using the generate.jsp.
Make your method return void instead of a String. An HTTP response can have only one body: either it's a file attachment, or an HTML page, but not both.
#JB Nizet Thank's for help. In my case, I retured ModelAndView ojbect when download failing to forward error page:
#RequestMapping(value = { "/downloadfile.action" }, method = RequestMethod.POST)
public ModelAndView downloadFile(HttpServletRequest req, HttpServletResponse res, Model model)
{
catch (Excetion e) {
return errorPage
}
}
I change that to return null
