HttpClientErrorException$BadRequest: 400 BAD REQUEST when service return []

I'm running a service and it works perfectly when it returns some entidade. But when it doesn't find any, I get the following error:
org.springframework.web.client.HttpClientErrorException$BadRequest: 400 BAD REQUEST: [{

What to do to work even when the entities list returns []?

Based on what I see from your log, your response object starts with an "[{..." so probably your server side is returning an list of RetornoServicoDto, not a single object that what you are asking the request for, since your problem is a bad request, would be great to see the service side that process the request to understand better.

XDocReport: Issue by filling tables with Freemarker in ODT-file

I tried to rebuild the sample from the XDocReport documentation, but when i try to create tables or fill them. It always fails due to the follwing error. I cannot figure out what the issue is...
I have updated all the dependencies and tried different syntax in the .odt file.
ERROR:

In the Developer class you have getFirstName instead of getName. Hence dev.name won't work.

Modify the Solr response using SolrJ

I'm using the SolrJ client to call the Solr service, is there any way to modify the response that I got from Solr like adding a new field in the response docs.
QueryResponse rsp = null;
if (server != null) {
try {
rsp = server.query(solrParams);
} catch (Exception e) {
e.getMessage();
}
}
If my response is something like below
{
"responseHeader":{
"status":400,
"QTime":15,
"params":{
"q":"*:*",
"indent":"true",
"wt":"json",
"group":"false"}},
"response":{"numFound":1,"start":0,"docs":[
{
"Name":"Shirt",
"inventory":"Nonn",
"launchYear":2004,
"Desc":"Men's Shirt",
"ilnNumbers":"25326,25338,25341,29617,39267",}
}}
I need to change this response to add a new field
{
"responseHeader":{
"status":400,
"QTime":15,
"params":{
"q":"*:*",
"indent":"true",
"wt":"json",
"group":"false"}},
"response":{"numFound":1,"start":0,"docs":[
{
"Name":"Shirt",
"inventory":"Nonn",
"launchYear":2004,
"myCustomField":"Test",
"Desc":"Men's Shirt",
"ilnNumbers":"25326,25338,25341,29617,39267",}
}}
Is this possible?

Define a POJO class for your schema along with getters and setters.
class POJO {
#Field
private String name;
#Field
private Integer inventory;
#Field
private Integer launchYear;
#Field
private String desc;
#Field
private String ilnNumbersl;
private String myCustomField;
public POJO(String name, Integer inventory, Integer launchYear, String desc, String ilnNumbersl) {
this.name = name;
this.inventory = inventory;
this.launchYear = launchYear;
this.desc = desc;
this.ilnNumbersl = ilnNumbersl;
}
//getters and setters for each instance member.
}
Now convert the solr response into List and add the required custom field to the each result returned by the query.
QueryResponse rsp = null;
if (server != null) {
try {
rsp = server.query(solrParams);
List<POJO> list = rsp.getBeans(POJO.class); // convert to list of POJO instance
// now add the custom field for each
} catch (Exception e) {
e.getMessage();
}
}

Try JsonResponceWriter from Solr Documentation.This will help you solve your problem.
<queryResponseWriter name="json" class="solr.JSONResponseWriter">
<!-- For the purposes of the tutorial, JSON response are written as
plain text so that it's easy to read in *any* browser.
If you are building applications that consume JSON, just remove
this override to get the default "application/json" mime type.
-->
<str name="content-type">text/plain</str>
</queryResponseWriter>
This will give you queryResponce in Text format. Modify That responce according to your use.

Getting a JSON object returned in Java

I'm trying to get a JSON object displayed via an API, but I get a error message along with it.
Here is the method that I've written:
public MarketDataListLevel1 getMarketDataTicker() {
try {
MarketDataListLevel1 md = CS.getMarketDataTicker();
log.info(md.toString());
return md;
}
catch ( Exception e) {
e.printStackTrace();
return null;
}
}
Where CS is an object that processes the JSON data from a URL..
For some reason, when I call that method, I'm getting the precise output that I want, but I also get these additional error messages that follow it, and I'm unsure why. Any help would be appreciated.
14:52:55.265 [default] [main] ERROR si.mazi.rescu.JSONUtils - Error unmarshalling from

java.lang.RuntimeException: Problem getting JSON object

Caused by: com.fasterxml.jackson.databind.JsonMappingException: Can not deserialize instance of com.xeiam.xchange.cs.dto.MarketData[] out of START_OBJECT token
at [Source: java.io.StringReader#5069bb01; line: 1, column: 2]
This is the format of the data what I want returned:
{"Bid":{"Price":204.08,"Size":1.0,"ExchangeID":"SMART","timeStamp":0},
"Ask":{"Price":203.2,"Size":0.0,"ExchangeID":"SMART","timeStamp":0},
"Last":{"Price":204.64,"Size":2.0,"ExchangeID":"SMART","timeStamp":0}}
And it seems to be fulfilling that.
MarketDataLevel1 is defined as:
public class MarketDataListLevel1 {
public MarketData[] MarketDataListLast;
public MarketData[] MarketDataListBid;
public MarketData[] MarketDataListAsk;
public MarketDataListLevel1(#JsonProperty("Bid") MarketData[] MarketDataListBid,#JsonProperty("Ask") MarketData[] MarketDataListAsk,#JsonProperty("Last") MarketData[] MarketDataListLast) {
this.MarketDataListBid = MarketDataListBid;
this.MarketDataListAsk = MarketDataListAsk;
this.MarketDataListLast = MarketDataListLast;
}
And MarketData as
public class MarketData {
public BigDecimal Price;
public BigDecimal Size;
public String ExchangeID;
public long timeStamp;
public MarketData(
#JsonProperty("Price") BigDecimal Price,
#JsonProperty("Size") BigDecimal Size,
#JsonProperty("ExchangeID") String ExchangeID,
#JsonProperty("timeStamp") long timeStamp) {
this.Price = Price;
this.Size = Size;
this.ExchangeID = ExchangeID;
this.timeStamp = timeStamp;
}
}

app engine req.getParameter with type float

I'm trying to do something very similar to the Guestbook which is in the App Engine tutorial (get started). However, I want to modified the types of the fields in the form. Eclipse doesn't show any error, but the server says:

My code is:
#Persistent
private Float distance;
public Greeting (User author, String content, Date date, String distance) {
this.author = author;
this.content = content;
this.date = date;
this.distance = Float.parseFloat(distance); }
}
public Float getDistance() {
return distance;
}
And Eclipse says everything is ok when I run the app, but when I open the file in my localhost domain, I see the error that I wrote you before.
However, if I change the code in something like this:
#Persistent
private String distance;
public Greeting (User author, String content, Date date, String distance) {
this.author = author;
this.content = content;
this.date = date;
this.distance = distance;
}
public String getDistance() {
return distance;
}
Thank you!

I think you have two problems:
Somewhere you have a Long field where data is a string and can not be converted to long.
Why are you converting distance parameter to Integer if you then assign it to a float field? Use Float.parseFloat(..) instead.

The error you're getting is when an already persisted entity is being read back from the datastore. It looks like you've already stored data which has a String property that you're now trying to read into an entity which has redefined that property as a Long - have you changed the type of the ID field at all?
