I want to uploal a doc file to the servlet using commons-fileupload-1.2.2.
I'm using this code in the front end:
<form action="fileuploader" method="post" enctype="multipart/form-data">
<br>File : <input type="file" name="uploadedFile">
<br><input type="submit">
and using this code in the servlet:
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
boolean isMultipart = ServletFileUpload.isMultipartContent(request);
}
but system gives me a this error
SEVERE: Servlet.service() for servlet FileUploaderServlet threw exception java.lang.ClassNotFoundException: org.apache.commons.fileupload.servlet.ServletFileUpload at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1680) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1526) at org.jspFileUploader.fileUploader.FileUploaderServlet.doPost(FileUploaderServlet.java:31) at javax.servlet.http.HttpServlet.service(HttpServlet.java:637) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:291) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:859) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:602) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) at java.lang.Thread.run(Unknown Source)
I think problem is in this line:
boolean isMultipart = ServletFileUpload.isMultipartContent(request);
Help me with this please
You need to drop the commons-fileupload.jar
and commons-io.jar
files in /WEB-INF/lib
folder of your webapp project. This folder becomes ultimately part of webapp's runtime classpath. Note that in a bit decent IDE like Eclipse/Netbeans/IntelliJ, you do not need to fiddle with buildpath properties afterwards. The IDE is perfectly aware that libraries in /WEB-INF/lib
are to be taken part of the runtime classpath, so it adds that to the build path automagically.
