Ignite c++ client for cassandra integration

I am developing an application for data communication in that i want to communicate to cassandra through ignite c++. when i try to put data to cassandra its works fine. but i can't get the data from the same.
here is my code.
test.h
namespace ignite
{
namespace examples
{
struct Test
{
Test()
{
// No-op.
}
Test(const std::string& assetid, const std::string& asset_desc, const std::string& groupid) :
assetid (assetid), asset_desc (asset_desc), groupid (groupid)
{
// No-op.
}
std::string ToString()
{
std::ostringstream oss;
oss << "Address [street=" << assetid << ", zip=" << asset_desc<< "]";
return oss.str();
}
std::string assetid;
std::string asset_desc;
std::string groupid;
};
}
}

I assume that's because you are using this:
<property name="storeKeepBinary" value="true"/>
Current implementation supports only BLOB serialization for binary objects. There is a ticket for this: https://issues.apache.org/jira/browse/IGNITE-5270

As far as you are using C++ to work with Ignite, you are also utilizing BinaryObjects. Current implementation of Cassandra store doesn't support BinaryObjects as cache keys and values.
Because of this, from Ignite C++ client you can't use Cassandra table with 1 partiton key ,3 clustering keys. You can only do it from java client configuring POJO persistence strategy and avoiding BinaryObjects.
There is also a ticket in Ignite JIRA to implement BinaryObjects support in Cassandra store: https://issues.apache.org/jira/browse/IGNITE-5270

Bean Velocity Config from xml to java

I'd like convert xml bean with velocity to config java class
This is old xml config:
<bean id="velocityConfig" class="org.springframework.web.servlet.view.velocity.VelocityConfigurer">
<property name="resourceLoaderPath" value="/WEB-INF/view/"/>
</bean>
<bean id="viewResolver" class="org.springframework.web.servlet.view.velocity.VelocityViewResolver">
<property name="cache" value="true"/>
<property name="prefix" value=""/>
<property name="suffix" value=".html"/>
<property name="exposeSpringMacroHelpers" value="true"/>
</bean>
And this is new java class config:
#Bean
public ViewResolver viewResolver()
{
VelocityViewResolver viewResolver= new VelocityViewResolver();
viewResolver.setPrefix("");
viewResolver.setSuffix(".html");
viewResolver.setCache(true);
return viewResolver;
}
#Bean
public VelocityConfigurer velocityConfig()
{
VelocityConfigurer velocityConfig = new VelocityConfigurer();
// ???????????
return velocityConfig;
}
How to do it?

VelocityConfig extends VelocityEngineFactory, so you can use the method setResourceLoaderPath:
velocityConfig.setResourceLoaderPath("/WEB-INF/View/");

Spring resource found but no beans are loaded

I am importing a spring xml configuration file from another project using import resource. The resource is apparently found since there is no error message saying it isn't, but none of the beans get loaded. Is there something I'm doing wrong here? I should note that when I run my integration tests from within eclipse it all works fine, but it blows up when running the same integration test from within a maven build.

Spring XML View Resolver not working

I have created a controller as below

public ModelAndView getAllassociations(HttpServletRequest request, HttpServletResponse response){
Map<String, Object> revenueData= new HashMap<String, Object>();
revenueData.put("1/20/2010", "$100,000");
revenueData.put("1/21/2010", "$200,000");
revenueData.put("1/22/2010", "$300,000");
revenueData.put("1/23/2010", "$400,000");
revenueData.put("1/24/2010", "$500,000");
return new ModelAndView("PdfRevenueSummary","revenueData",revenueData);
}
}

since the tiles.xml is working fine so i have not posted the code part.
the Issue in the above code is that when i return the view from controller by
return new ModelAndView("PdfRevenueSummary","revenueData",revenueData);
it is not getting redirected to the class PdfRevenueReportView as given in the spring-pdf-views.xml
so plz help me to get out of this problem
Hopes the above question is clear....

after 2 days, i found what i needed
the issue was simple just made the class PDFDocumentController to extend the Class AbstractController
just made
public class PDFDocumentController extends AbstractController
instead of
public class PDFDocumentController extends SecurityController

hibernate always deletes all data from a table on its own

Hi i am developing a spring mvc app thats using hibernate to connect to a mysql database that stores files.
I have two methods. one that adds all files from a specific file path of my choosing and another method that invokes a query to return me a list of the files stored from mysql.
The issue is this. When i execute the first method on its own ie populating the database, it works fine i can see the contents of that table from mysql command line. however, when i then execute the query method right after populating it, the contents of that said table is completely gone instantly. Its as if hibernate only stored the data in the mysql temporarily or somewhere in mysql, it deleted data imediatly and doesnt keep it their.
this is the method that populated the table:
/**
* Test Method: ideal for another class to do this kind of work and this
* pass the FileObject into this class
*/
public void addSomeFiles() {
System.out.println("addSomeFiles");
File dir = new File(picturesPath);
String[] fileNames = dir.list();
for (int i = 0; i < fileNames.length; i++) {
System.out.println(fileNames[i]);
File file = new File(picturesPath + "\\" + fileNames[i]);
if (file.isFile()) {
FileObject fileO = contstructFileObject(file);
if (fileO == null) {
System.out.println("fileO is null!!!!!");
} else {
// addFile(fileO);
dbFileHelper.addFile(fileO);
}
}
}
System.out.println("//////////////");
// File file;
}
.........Hibernate template class........
public class DbFileHelper implements DbFileWrapper {
private HibernateTemplate hbTemplate;
//private static final String SQL_GET_FILE_LIST = "select filename, size, id, type from fileobject";
private static final String SQL_GET_FILE_LIST = "select new FileObject(filename, size, id, type) from FileObject";
public DbFileHelper() {
}
public void setHbTemplate(HibernateTemplate hbTemplate) {
System.out.println("setHbTemplate");
System.out.println("///////////////////");
System.out.println("///////////////////");
System.out.println("///////////////////");
this.hbTemplate = hbTemplate;
}
// ////////////////////////////////////////////////
#Override
public String addFile(FileObject file) {
// TODO Auto-generated method stub
System.out.println("addFile using hibernate");
if (hbTemplate == null) {
System.out.println("hbTemplate is null!! why?");
}
hbTemplate.saveOrUpdate(file);
hbTemplate.flush();
return "added succesfuly";
}
And here is the other method that makes the query:
........................
public JSONArray getFileList(String type){
return constructJsonArray(dbFileHelper.getFileList(ALL));
}
private JSONArray constructJsonArray(List<FileObject> fileList ){
JSONArray mJsonArray = new JSONArray();
for (int i = 0; i < fileList.size(); i++) {
System.out.println("fileName = " + fileList.get(i).getFilename() );
//mJson.put("Filename", fileList.get(i).getFileName() );
mJsonArray.add( new JSONObject().put("File ID", fileList.get(i).getId() ));
mJsonArray.add( new JSONObject().put("Filename", fileList.get(i).getFilename() ));
mJsonArray.add( new JSONObject().put("File type", fileList.get(i).getType()));
mJsonArray.add( new JSONObject().put("File Size", fileList.get(i).getSize()));
}
return mJsonArray;
}
..........hibernate Template class.......
private static final String SQL_GET_FILE_LIST = "select new FileObject(filename, size, id, type) from FileObject";
#Override
public List<FileObject> getFileList(String type) {
// TODO Auto-generated method stub
List<FileObject> files = hbTemplate.find(SQL_GET_FILE_LIST);
//hbTemplate.flush();
return files;
}
..........
Finally here is a print screen of what i originaly put inside my table but dissapears on its own:

Am i missing something here?

i have fixed the problem
i changed <prop key="hibernate.hbm2ddl.auto">create</prop>
to <prop key="hibernate.hbm2ddl.auto">update</prop> and it worked

Are you creating/destroying the SessionFactory between calls? Could you have the hbm2ddl.auto property set to create-drop?
Actually, can you show the Hibernate settings?
Reference
Hibernate Core Reference Guide
Table 3.7. Miscellaneous Properties

In my case also table was getting deleted automatically, following solution worked for me:
org.hibernate.dialect.MySQL8Dialect
Appending the version number with the MySQL Dialect.
Because commit was not getting executed earlier with org.hibernate.dialect.MySQLDialect.
