    copied!<p>I'm trying to implement upload code for grails. When the file is processed on my controller I get this error:</p> <pre><code>ERROR errors.GrailsExceptionResolver - Exception occurred when processing request: [POST] /com.jason.score/fileResource/uploads Stacktrace follows: groovy.lang.MissingMethodException: No signature of method: static org.hsqldb.types.Binary.storeMyFileMethod() is applicable for argument types: (org.springframework.web.multipart.commons.CommonsMultipartFile) values: [org.springframework.web.multipart.commons.CommonsMultipartFile@1a17db8] at com.jason.score.FileResourceController$_closure4_closure6.doCall(FileResourceController.groovy:73) at com.jason.score.FileResourceController$_closure4.doCall(FileResourceController.groovy:72) at com.jason.score.FileResourceController$_closure4.doCall(FileResourceController.groovy) at java.lang.Thread.run(Thread.java:662) </code></pre> <p>My controller function looks like this:</p> <pre><code> def uploads = { Collection result = [] Binary binary request.getFileNames().each { binary = Binary.storeMyFileMethod(request.getFile(it)) result &lt;&lt; [name: binary.getFileName(), size: binary.getFileSize()] } render result as JSON } </code></pre> <p>My view looks like this:</p> <pre><code> &lt;g:form name="fileupload" url="[action:'uploads',controller:'fileResource']" method="POST" enctype="multipart/form-data"&gt; .... &lt;input type="file" name="files[]" multiple&gt; &lt;/g:form&gt; </code></pre> <p>Can anyone explain what is going wrong and how I can process each file that is uploaded (can be multiple files)?</p>
