Mail function using springmvc and extjs

**sachintaware** · 30 Mar 2012 4:25 AM

I am working on a mail application using springMVC and hibernate.
I have used the MailService for sending the email.But,I get the following error
Debug log for mail

This seems fine and the mails are sent properly as required.
Here,is the error in firebug and due to this I don't get a success message of the mail delivery.
In firebug console I get an error like this under the response tab.

Code:

uncaught exception: [Exception... "'You're trying to decode an invalid JSON String: ' when calling method: [nsIDOMEventListener::handleEvent]" nsresult: "0x8057001c (NS_ERROR_XPC_JS_THREW_JS_OBJECT)" location: "JS frame :: resource://firebug_rjs/net/spy.js :: callPageHandler :: line 798" data: no]`

and this under XML tab

Code:

XML Parsing Error: no element found Location: moz-nullprincipal:{564d3946-b1b0-48d4-8791-8a5ea8069a85} Line Number 1, Column 1:

^

But,I checked the returned Json and it is in the correct format.And it is returned before the mail function is even called.

This is my config file for spring bean

Code:

<!--*************************** E-Mail bean******************************--> 
     
     <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">

        </property>
        <property name="subject" value="Alert - Exception occurred"/>
    </bean>

Can someone guide me through this??

Thanks

I noticed that the PHP error message you posted shows the file name as applicationContect.xml instead of applicationContext.xml. That may be the problem. Also, I kinda confused about the use of PHP when you have a Java Web container on the backend.

Regardless, as for file paths, Spring uses root-relative paths in its config files. Note that I never load the application context manually. I let the web container do all the work by specifying everything in Tomcat's web.xml.

Below is a pared-down example of my web.xml which loads the application and servlet context configs for me, where I also have a Spring Security config in there. Note that I'm old-school/retarded and like '.action' on the end of my URL mappings. A more modern approach would be to place all of your MVC-related URL mappings into an 'mvc' context instead:

Code:

  <servlet-mapping>
    <servlet-name>myapp</servlet-name> 
    <url-pattern>*.action</url-pattern>
  </servlet-mapping>

  <!-- The client app uses a 15 minute session timeout, where a 2 minute slop factor is 
       added here. -->
  <session-config>
    <session-timeout>17</session-timeout> 
  </session-config>

  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
  </welcome-file-list>
 </web-app>

For thoroughness, here's my applicationContext.xml as well, noting that I break everything out into separate XML files for compartmentalization/ease of reading:

It's saying the JSON is invalid. Have you made sure it's valid JSON?

**sachintaware** · 30 Mar 2012 11:05 AM

Yes the JSON is very much valid.Infact it is returned even before I go to the email function.(I use store content already fetched for sending mails).So,the JSON is returned before this.Also,when I check it in CHROME browser,no such error is generated and I get a Mail success message

. Mozilla FF gives this error and gets stuck on the progress bar once I submit the mail form.

This is what I get under the XML tab in firebug,tried to google and learnt that response may be a problem.I have added the js that throws the error with line number.Please guide me over this.

Code:

XML Parsing Error: no element found Location: moz-nullprincipal:{564d3946-b1b0-48d4-8791-8a5ea8069a85} Line Number 1, Column 1:

Code:

originalHandler.handleEvent(event);                                          spy.js (line 798)

This is what I return on success and failure.Works fine in Chrome but not in FF

Code:

var f = Ext.getCmp('sendEmailForm');
             f.form.submit({
                 reset: true, 
                 url:'email/view.action',

                                    Ext.Msg.alert('Status', 'Mail has been sent Successfully!!', function(btn, text){

I am still stuck with the issue.Can you please suggest any clue?

Thanks

**friend** · 14 May 2012 5:36 AM

So you have something to compare against, here's my Spring bean config for the JavaMailSender:

Code:

  <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
    <property name="host" value="smtp.gmail.com" />
    <property name="port" value="465" />
    <property name="protocol" value="smtps" />
    <property name="username" value="yourGmailAccountName@gmail.com" />
    <property name="password" value="yourpassword" />
    <property name="javaMailProperties">
      <props>
        <prop key="mail.smtps.auth">true</prop>
        <prop key="mail.smtps.starttls.enable">true</prop>
        <prop key="mail.smtps.debug">true</prop>
      </props>
    </property>
  </bean>

And here's my Controller method which constructs/sends email, noting that I go overboard on input parameter checking, in case a user tries hacking around with the request parameters. Note that I'm using the Jackson JSON Mapping view support in Spring 3.1, hence the return type annotation of @ResponseBody where Spring auto-magically handles the content type and JSON conversion:

Code:

  @RolesAllowed({Utility.ROLE_ADMIN,Utility.ROLE_EMAIL_USERS})
  @RequestMapping("/user/emailSubmit")
  public @ResponseBody Map<String,Object> emailSubmit(Authentication auth, 
      @RequestParam("from") String from, @RequestParam("to") String to, @RequestParam("subject") String subject, 
      @RequestParam("message") String message)
  {
    // simple utility method which constructs a new Map and adds
    // a default "success"/true  key/value pair.
    Map<String,Object> results = Utility.getJsonResultMap();

    if (from == null || from.isEmpty()) {
      results.put("success", false);
      results.put("title", "Error");
      results.put("msg", "Please enter a 'From' email address.");
    }
    else if (!Utility.isValidEmailAddress(from)) {
      results.put("success", false);
      results.put("title", "Error");
      results.put("msg", "Invalid 'From' email address.");
    }
    else if (to == null || to.isEmpty()) {
      results.put("success", false);
      results.put("title", "Error");
      results.put("msg", "Please enter one or more 'To' email addresses.");
    }
    else if (subject == null || subject.isEmpty()) {
      results.put("success", false);
      results.put("title", "Error");
      results.put("msg", "Please enter a 'Subject' for your email.");
    }
    else if (message == null || message.isEmpty()){
      results.put("success", false);
      results.put("title", "Error");
      results.put("msg", "Please enter a message for the body of your email.");
    }
    else {
      
      MimeMessage mailMessage = this.mailSender.createMimeMessage();
      MimeMessageHelper helper = null;

      try
      {
        helper = new MimeMessageHelper(mailMessage, true);
        
        String[] recipients = to.split(",");
        for (String address : recipients) {
          if (!Utility.isValidEmailAddress(address)) {
            results.put("success", false);
            results.put("title", "Error");
            results.put("msg", "Email '" + address + "' in the list of recipients doesn't appear to be valid.");
            return results;
          }
          
          helper.setTo(address.trim());  
        }      
        
        
        helper.setFrom(from);
        helper.setSubject(subject);
        helper.setSentDate(new Date());
        helper.setText(message, true);

        this.mailSender.send(mailMessage);
        
        results.put("msg", "Email sent successfully.");
        results.put("title", "Email Sent");
        
      } 
      catch (Exception e)
      {
        logger.error("Error sending user email: " + e);
        results.put("success", false);
        results.put("title", "Error sending email");
        results.put("msg", "An error occurred while attempting to send your email. Please contact Tech Support.");
      } 
    }
    
    return results;
  }

This code is currently used in a production app and works well.

Thanks @friend

I have problem with applicationContext.xml for bean definition in my project.

Code:

ApplicationContext context = new FileSystemXmlApplicationContext("C:/Documents and Settings/Administrator/workspace/StaffingApplication/WebContent/WEB-INF/applicationContext.xml");

I have to give the absolute path here(on my machine) and in production for it to work i have to give a relative one.

When I try to give a relative path I get an error

Code:

File not found exception:Cannot find applicationContext.xml at given path.

For example this one doesn't work.So the path has to be given relative to .java files or .class files in the classes folder.(Confused a bit)

Code:

ApplicationContext context = new FileSystemXmlApplicationContext("WEB-INF/applicationContext.xml");

I tried to read about it and went through examples,but I am not able to resolve it.(Learnt that FileSystemXmlApplicationContext requires the entire path )
This is the navigation view of my app.How can I resolve this issue.Please throw some light on it.

I noticed that the PHP error message you posted shows the file name as applicationContect.xml instead of applicationContext.xml. That may be the problem. Also, I kinda confused about the use of PHP when you have a Java Web container on the backend.

Regardless, as for file paths, Spring uses root-relative paths in its config files. Note that I never load the application context manually. I let the web container do all the work by specifying everything in Tomcat's web.xml.

Below is a pared-down example of my web.xml which loads the application and servlet context configs for me, where I also have a Spring Security config in there. Note that I'm old-school/retarded and like '.action' on the end of my URL mappings. A more modern approach would be to place all of your MVC-related URL mappings into an 'mvc' context instead:

Code:

  </session-config>

For thoroughness, here's my applicationContext.xml as well, noting that I break everything out into separate XML files for compartmentalization/ease of reading:

       If your application requires any configuration properties, you can
       load the Properties files from the classpath, as a named bean.  You can
       then inject the bean into any classes which need access to the properties.
          
       In this example, global.properties is placed in the root of the /src folder. 
       
       If you need to dynamically insert properties into your application's context
       config at startup,  visit the documentation for PropertyPlaceholderConfigurer.   
       =============================================================================    -->
  <bean id="globalProperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
    <property name="location" value="classpath:global.properties"/>
  </bean>

</beans>

@friend
Thanks for the inputs,will go through for sure.
That was a typo(applicationContext it is as in the layout image.)!!!

Also,I changed the tag mistakenly to PHP and did not notice.When you said I realised that's why they are showing up in colors.

Will edit the question.
This is the exact error

Code:

SEVERE: Servlet.service() for servlet [StaffingApplication] in context with path [/StaffingApplication] threw exception [Request processing failed; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from file [C:\Documents and Settings\Administrator\workspace\StaffingApplication\WebContent\WEB-INF\applicationContext.xml]; nested exception is java.io.FileNotFoundException: C:\Documents and Settings\Administrator\workspace\StaffingApplication\WebContent\WEB-INF\applicationContext.xml (The system cannot find the path specified)] with root cause
java.io.FileNotFoundException: C:\Documents and Settings\Administrator\workspace\StaffingApplication\WebContent\WEB-INF\applicationContext.xml (The system cannot find the path specified)

Thanks

I think the root cause of your problem is attempting to manually load the application context. Is there a reason you need to do so?
