Caused by: net.sf.jasperreports.engine.fill.JRExpressionEvalException: Error evaluating expression :
Source text : $F{Estimate Request Of Case}
getting Exception in this code:
reportBuilder.setDataSource(createDataSource(reportColumns, collectiveDataArrayList)).toXls(xlsExporter);
How can i fix this ?? Can anyone help me ??
Java Code
private JRDataSource createDataSource(List<String> reportColumns, List<Object[]> arrayListData) {
DRDataSource dataSource = null;
String[] reportCol = new String[reportColumns.size()];
int i = 0;
for (String repCol : reportColumns) {
reportCol[i] = repCol;
i++;
}
dataSource = new DRDataSource(reportCol);
for (Object[] listData : arrayListData) {
dataSource.add(listData);
}
return dataSource;
}

Change type of Estimate Request Of Case from Charactor to String

Java Download Large File Stops Unexpectedly

I am downloading a large file (500MB to 1GB) from a java spring tomcat application.
The method below to download the file has been working great in the past, but today it started behaving weirdly. Only about the first 20MB - 50MB would get downloaded before the browser (chrome) thought the file was finished.
#RequestMapping(value = "/DownloadPDFSaved/{group}", method = RequestMethod.GET)
public void downloadGroup(#PathVariable String group, HttpServletResponse response) {
if(!StringUtils.hasText(group)) {
response.sendError(400, "Group is empty");
return;
}
InputStream is = new FileInputStream(new File(getPDFZipFilePathForGroup(group)));
IOUtils.copy(is, response.getOutputStream());
response.flushBuffer();
}
In the tomcat logs, I can see a ClientAbortException, but it doesn't give too much useful information.
Do I need to set the content length? If so, would I set the content length to the size of the file? Can you see anything else that would be causing an issue downloading a large zip file?

Adding the content-length header seems to fix the problem. I am guessing that the browser was cutting the download short without the header and that was causing the ClientAbortException.
Here is the updated and working code:
#RequestMapping(value = "/DownloadPDFSaved/{group}", method = RequestMethod.GET)
public void downloadGroup(#PathVariable String group, HttpServletResponse response) {
if(!StringUtils.hasText(group)) {
response.sendError(400, "Group is empty");
return;
}
File zipFile = new File(getPDFZipFilePathForGroup(group));
//set content-length header
response.setHeader("Content-Length", Long.toString(zipFile.length()));
InputStream is = new FileInputStream(zipFile);
IOUtils.copy(is, response.getOutputStream());
response.flushBuffer();
}

cached Row set populate method not working for sqlserver database

I wrote following code
public JSONObject getListByUserSQLQuery(JSONObject preparedQuery,final int jsonType,final Map<Object, Object>mMap,final JSONObject pagination)
throws Exception {
SqlParameterSource parameterSource=getMapFromParam(preparedQuery);
final CachedRowSet cachedRowSet=new CachedRowSetImpl();
System.out.println(pagination);
Object obj=namedParameterJdbcTemplate.query(preparedQuery.getString("query"), parameterSource, new ResultSetExtractor<Object>() {
#Override
public Object extractData(ResultSet rs) throws SQLException,
DataAccessException {
ResultSetMetaData rsmd = rs.getMetaData();
if(pagination.has("_LIMIT_")){
cachedRowSet.setPageSize(pagination.getInt("_LIMIT_"));
cachedRowSet.setFetchSize(pagination.getInt("_LIMIT_"));
}
if( pagination.has("_START_") && cachedRowSet.getPageSize()!=0){
cachedRowSet.populate(rs, pagination.getInt("_START_")+1);
}else{
cachedRowSet.populate(rs);
}
Object obj=null;
if (jsonType == CommonConstants.JSON_TYPE_MOBILE) {
obj = formatOtherData(cachedRowSet, rsmd, mMap);
} else if (jsonType == CommonConstants.JSON_TYPE_PLATEFORM) {
obj = formatPlatformData(cachedRowSet, rsmd);
} else if (jsonType == CommonConstants.JSON_DOWNLOAD_MOBILE) {
obj = formatOtherDownloadData(cachedRowSet, rsmd);
} else{
throw new Exception("Unknown Format");
}
return obj;
}
});
Output for this code is as follows
{"_START_":0,"_LIMIT_":10}

Thanks in advance

dynamic json response: Could not read JSON: N/A (through reference chain) jackson fasterxml

I want to access a REST api with a variable amount of product codes as parameters.
The JSON response will give me a token for every code I submit.
The problem is the root elements of the json response will be the product codes I submitted, so I can't use the standard #JsonProperty annotation in my receiving class.
How to go about this ?!
For instance:
URL: http://example.com/listing?code=123456&code=456789
Response:
{
"123456": {
"code": 123456,
"primaryToken": "4176d70b52c3f3287c7"
},
"456789": {
"code": 456789,
"primaryToken": "6ddsd25a36bdf7fb"
}
}
I call the API like this :
ImageListingResponse response = restTemplate.getForObject(url, ImageListingResponse.class, apiArguments);
And my ImageListingResponse class is :
#JsonIgnoreProperties(ignoreUnknown=true)
public class ImageListingResponse {
private Map<String, ImageResponse> response;
#JsonAnyGetter
public Map<String,ImageResponse> get() {
return response;
}
#JsonAnySetter
public void set(String name, ImageResponse value) {
response.put(name, value);
}
}
ImageResponse :
#JsonIgnoreProperties(ignoreUnknown=true)
public class ImageResponse {
#JsonProperty("code")
private Long code;
#JsonProperty("primaryToken")
private String primaryToken;
...
}
Thanks in advance !
EDIT: forgot the stacktrace :
org.springframework.http.converter.HttpMessageNotReadableException: Could not read JSON: N/A (through reference chain: be.kava.farma.modules.prins.ImageListingResponse["123465"]); nested exception is com.fasterxml.jackson.databind.JsonMappingException: N/A (through reference chain: be.kava.farma.modules.prins.ImageListingResponse["123456"])

Isn't it just because you didn't initialize the Map<String, ImageResponse> response field?

ClassNotFoundException YaHP Converter

I'm trying to use YaHP Converter API.
First I want to convert a simple html code, then I will take mine from a filter.
I used maven to import YaHP.
Here what I have :
#RequestMapping("/edition")
public void buildPdf(HttpServletRequest request, HttpServletResponse response)
throws IOException, CConvertException {
String myHtml = "<div><h1>test html</h1></div>";
String htmlContents = myHtml;
CYaHPConverter converter = new CYaHPConverter();
Map properties = new HashMap();
List headerFooterList = new ArrayList();
properties.put(IHtmlToPdfTransformer.PDF_RENDERER_CLASS, IHtmlToPdfTransformer.FLYINGSAUCER_PDF_RENDERER);
OutputStream os = response.getOutputStream();
response.reset();
response.setContentType("application/pdf");
// String[] fname = filename.split("\\\\");
// if (fname[0].equals(filename)) {
// fname = filename.split("/");
// }
String pdfName = "export";
response.setHeader("Content-Disposition", "attachment; filename= \"" + fileName + ".pdf\"");
converter.convertToPdf(htmlContents, IHtmlToPdfTransformer.A4P, headerFooterList, "file:///temp/html/", os,
properties);
response.flushBuffer();
// super.buildPdfReport(request, response);
}
I get :

SEVERE: Error while getting transformer 'org.allcolor.yahp.cl.converter.CHtmlToPdfFlyingSaucerTransformer' ! : org.allcolor.yahp.cl.converter.CHtmlToPdfFlyingSaucerTransformer
I would appreciate helping me to resolve my issue.

Add the following dependency
<dependency>
<groupId>com.google.code.maven-play-plugin.org.allcolor.yahp</groupId>
<artifactId>yahp-internal</artifactId>
<version>1.3</version>
</dependency>

You need to add library with class org.allcolor.yahp.cl.converter.CHtmlToPdfFlyingSaucerTransformer to your Tomcat classpath.
For example you could add this library to %CATALINA_HOME%\lib directory.
