not getting model filled from jsp in spring mvc

not getting model filled from jsp in spring mvc - java

Same error even adding #ModelAttributeI am not able to get the model class filled while clicking on button on jsp. In Database a new field is created but value are going null(Because model is not getting filled).
Please help me out on this.
Thanks in advance.
My Model class is:
package model;

private int conversionId;
#Column(name = "conversionFrom")
private String conversionFrom;
#Column(name = "conversionFromValue")
private int conversionFromValue;
#Column(name = "conversionTo")
private String conversionTo;
#Column(name = "conversionToValue")
private int conversionToValue;
#Column(name = "conversionDate")
private Date conversionDate;
public int getConversionId() {
return conversionId;
}
public void setConversionId(int conversionId) {
this.conversionId = conversionId;
}

do the changes as mentioned by #alan and also make following changes to your js function:
function SaveConversion() {
var params = $("#Conversion_form").serialize();
alert(params);
$.ajax({
method : "POST",
url : "saveConversion",
data : params, //this line is changed
success : function(result) {
alert(result);
$("#responseDiv").html(result);
messageDisplay();
return false;
}
})
}
the js function as per the question was sending only one parameter "param" which had value of serialized form value. After making above change it should be working. I have verified the same using network tab of the browser. You can see it for yourself if needed.

If you want to Spring to automatically bind the submitted parameters to a Conversion instance then you need to use the #ModelAttribute annotation in your method signature.
#RequestMapping("/saveConversion")
public ModelAndView saveConversion(#ModelAttribute Conversion conversion, Model model) throws ServletException, IOException, ParseException {
System.out.println("In saveConversion");
Boolean boolean1 = serviceDao.setConversion(conversion);
if (boolean1) {
model.addAttribute("conversionSaved", "Conversion saved successfully!");
} else {
model.addAttribute("conversionSaved", "Conversion Not saved!");
}
return new ModelAndView("setConversion");
}
http://docs.spring.io/spring/docs/current/spring-framework-reference/html/mvc.html#mvc-ann-modelattrib-method-args
An #ModelAttribute on a method argument indicates the argument should
be retrieved from the model. If not present in the model, the argument
should be instantiated first and then added to the model. Once present
in the model, the argument’s fields should be populated from all
request parameters that have matching names. This is known as data
binding in Spring MVC, a very useful mechanism that saves you from
having to parse each form field individually.

Unable ot get openJPA working with Tomcat 8

Looking at your source code, I found the problem : your persistence.xml is located in src/main/webapp/META-INF instead of src/main/resources/META-INF.
Move it to src/main/resources/META-INF and remove the javax.persistence.jdbc.driver property and it will work.

406 Not acceptable error when returning JSON in Spring MVC

I am working on application which will just used as a restful services and the response has to be returned as JSON.y p
I am on Spring MVC and following this article to achieve the same
https://www.mkyong.com/spring-mvc/spring-3-mvc-and-json-example/
I have added Jackson jar in my POM, enabled response body and mvc-annotation-driven annotation.
But still on firing the url i get 406 Not acceptable error.
I have tried firing with a rest client and adding request headers for Content-Type and Accept with "application/json".

}
In addition i have a POJO of employee class with firstname and lastname as private methods and setter/getter as public methods.

Spring 4.3.10: I used the below settings to resolve the issue.
Step 1: Add the below dependencies
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.6.7</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.6.7</version>
</dependency>
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-core-asl</artifactId>
<version>1.9.13</version>
</dependency>
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-mapper-asl</artifactId>
<version>1.9.13</version>
</dependency>
Step 2: Add the below in your MVC DispatcherServlet context configuration:
<mvc:annotation-driven content-negotiation-manager="contentNegotiationManager"/>
<bean id="contentNegotiationManager"
class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
<property name="favorPathExtension" value="false"/>
<property name="favorParameter" value="true"/>
<property name="ignoreAcceptHeader" value="false" />
</bean>
Since spring 3.2, as per the default configuration favorPathExtension is set as true, because of this if the request uri have any proper extensions like .htm spring will give priority for the extension. In step 2 I had added the contentNegotiationManager bean to override this.

I could resolve the problem with my above code itself.
Problem was the jackson mapper jar was not present in the classpath.
So it was not working.
In Eclipse For Maven projects you have to force update such that the jar can come in the classpath.
Ideally there should been an error from the spring framework about the class not being loaded. The error itself was misleading.

Error:

EDIT: It says class 'com.maven.controller.HelloController' not found.
I see that you have put your com.maven.controller.HelloController.java file under src\main\resources folder.
It should be under src\main\java folder. So the hierarchy should be like
src
|-main
|-java
|-com
|-maven
|-controller
|-HelloController.java
The reason is the directory structure followed by maven detects java files only if it's placed under this hierarchy src\main\java, if you are using default configuration.
Can you right click on project and go to Properties > Java Build Path > Source and check whether src\main\java entry is there in the build path list or not? If not add it and try again.

After lots of struggle i got the answer, i had error in spring.xml file. check the solutions.
i need to add below code only in spring.xml file.
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN"
"http://www.springframework.org/dtd/spring-beans-2.0.dtd">
previously i was using below code

xsi:schemaLocation="http://www.springframework.org/schema/beans

for above code i need to change pom.xml file, i mean need to add more dependency.

My problem is When I run the application again all the data that was saved earlier vanishes even though I have set the hbm2ddl.auto property to update mode.
I have set my show_sql property as "true" to check the queries that are getting fired but there are no delete queries which are getting fired.
Is there any other important thing that I am missing here.

See comments and read Hibernate manual here
<property name="hbm2ddl.auto">update</property>
setting above property Drop and re-create the database schema on startup
consider below comments from hibernate manual.
Hibernate's automatic session management for persistence contexts is particularly useful in this context. The hbm2ddl.auto option turns on automatic generation of database schemas directly into the database. This can also be turned off by removing the configuration option, or redirected to a file with the help of the SchemaExport Ant task.

hbm2ddl.auto is for the validation of the database schema, which doesn't have any meaning here.
You have to commit your values, if not they are not permanently stored in the database.

I found the solution. there were a lot of messy project dependencies in my Tomcat so I deleted that instance of Tomcat and reconfigured it for my project. Then I cleaned my project and now everything is working fine as it should be. Thanks for taking time to post the answers.

Spring REST MultipartFile file is always null

I'm trying to set up a simple upload with html and Spring 3.0.6 using REST services. I've followed the tutorial online but the MultipartFile parameter is always null. Here's the config and code:
application-context.xml:
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="maxUploadSize" value="2000000"/>
</bean>
pom.xml:
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>2.1</version>
</dependency>
<dependency>
<groupId>commons-fileupload</groupId>
<artifactId>commons-fileupload</artifactId>
<version>1.2.2</version>
</dependency>
html:
<html>
<head>
<title>Upload a file please</title>
</head>
<body>
<h1>Please upload a file</h1>
<form method="post" action="/site/restServices/artworkUpload/" enctype="multipart/form-data">
<input type="text" name="name"/>
<input type="file" name="file"/>
<input type="submit"/>
</form>
</body>
</html>
REST Controller:
#POST
#Path("/artworkUpload")
public String uploadFile(#RequestParam("name") String name,
#RequestParam("file") MultipartFile file) {
try {
if (!file.isEmpty()) {
byte[] bytes = file.getBytes();
// store the bytes somewhere
return "redirect:uploadSuccess";
} else {
return "redirect:uploadFailure";
}
}
catch (Exception ex)
{
}
return null;
}
I copied the example from Spring's tutorial but no matter what I change, the file parameter is always null. "name" will have the value in the text box but file will be null.
I have also tried using Jersey and I receive the InputStream for the file but the FormDataContentDisposition is null so I can't determine the file type.
This is running on Jetty as well.
What am I missing?

As I remember I solved same issue by putting additional libs to my build path:
commons-fileupload-1.2.2.jar
commons-io-2.1.jar
I hope this will help you.
Edit.
Ok. At last I had time for this issue. First of all, why do you use standart java features for building rest service (annotations #POST, #Path)? Because with Spring it is better to use spring MVC futures for REST. There is a lot of information about this in internet. Here is special part in reference documentation. Also here is good article on IBM site. Also very good description on how to build REST controller with Spring MVC is in Spring in Action (last 3-d edition).
Here how I have implemented simple file uploading functionality:
Rest controller:
#Controller
#RequestMapping("/rest/files")
public class FilesController {
...
#RequestMapping(value="/rest/files", method=RequestMethod.POST)
public String uploadFile(#RequestParam("name") String name,
#RequestParam("file") MultipartFile file) {
try {
if (!file.isEmpty()) {
byte[] bytes = file.getBytes();
// store the bytes somewhere
return "redirect:uploadSuccess";
} else {
return "redirect:uploadFailure";
}
}
catch (Exception ex)
{
}
return "/testFileDownload";
}
}

<entry key="file" value="multipart/form-data"/>
<entry key="html" value="text/html"/>
</map>
</property>
<property name="viewResolvers">

<property name="prefix" value="/WEB-INF/views/"/>
<property name="suffix" value=".jsp"/>
</bean>
</list>
</property>
</bean>
I hope I'm not wasted my time and this is still necessary for you. )
