title: Spring Forms - How to Check for Error on Specific Path
body: <p>I'm using the Spring Form library to handle a search page in my application.  Here is a snipped from my DD showing the bean configuration:</p>
  
  <pre><code>&lt;bean name="/search.html" class="myapp.web.AccountSearchController"&gt;
          &lt;property name="sessionForm" value="true"/&gt;
          &lt;property name="commandName" value="searchAccounts"/&gt;
          &lt;property name="commandClass" value="myapp.service.AccountSearch"/&gt;
          &lt;property name="validator"&gt;
              &lt;bean class="myapp.service.AccountSearchValidator"/&gt;
          &lt;/property&gt;
          &lt;property name="formView" value="accountSearch"/&gt;
          &lt;property name="successView" value="accountSearch"/&gt;
      &lt;/bean&gt;
  </code></pre>
  
  <p>The validator class is quite simple:</p>
  
  <pre><code>package myapp.service;
  
  import org.springframework.validation.Validator;
  import org.springframework.validation.Errors;
  
  import org.apache.commons.logging.Log;
  import org.apache.commons.logging.LogFactory;
  
  public class AccountSearchValidator implements Validator {
  
      /** Logger for this class and subclasses */
      protected final Log logger = LogFactory.getLog(getClass());
  
      public boolean supports(Class clazz) {
          return AccountSearch.class.equals(clazz);
      }
  
      public void validate(Object obj, Errors errors) {
          AccountSearch accountSearch = (AccountSearch) obj;
          if (accountSearch == null) {
              errors.rejectValue("domainName", "error.accountSearch.neither-specified", null, "Value required.");
          } else if (accountSearch.getAccountId().isEmpty() &amp;&amp; 
                     accountSearch.getDomainName().isEmpty() ) {
              errors.rejectValue("domainName", "error.accountSearch.neither-specified", null, "Value required.");
          }
      }
  }
  </code></pre>
  
  <p>In my JSP, my form is displayed in an HTML table.  I want field specific errors to be displayed under the respective field as a separate table row.  Here's a snippet:</p>
  
  <pre><code>            &lt;tr&gt;
                  &lt;td align="right" valign="top"&gt;&lt;form:label path="domainName"&gt;Domain Name&lt;/form:label&gt;:&lt;/td&gt;
                  &lt;td&gt;&lt;form:input path="domainName" size="30"/&gt;&lt;/td&gt;
              &lt;/tr&gt;
              &lt;tr&gt;
                   &lt;td&gt;&amp;nbsp;&lt;/td&gt;
                   &lt;td&gt;&lt;form:errors path="domainName" cssClass="error"/&gt;&lt;/td&gt;
              &lt;/tr&gt;
  </code></pre>
  
  <p>The question I have is - how can I make the output of the error row conditional on the existence of the error?  Is the Validator instance accessible from my JSP?  What would the test be for a c:if tag?</p>
  
  <p>Thanks,</p>
