Having trouble sending a zip file from a Java servlet to a JavaScript client. The zip archive is generated successfully on disk, but there's an issue with transferring it to the client.
The code snippet responsible for sending the file in the doPost method is as follows:
String path = getServletContext().getRealPath("/") + "generatedApps/";
String fileName = appName + "Archive.zip";
File f = new File(path + fileName);
response.setContentType("application/zip");
response.setContentLength((int)f.length());
response.addHeader("Content-Encoding", "gzip");
response.addHeader("Content-Disposition","attachment;filename=\"" + fileName + "\"");
byte[] arBytes = new byte[(int)f.length()];
FileInputStream is = new FileInputStream(f);
is.read(arBytes);
ServletOutputStream op = response.getOutputStream();
op.write(arBytes);
op.flush();
Here's the Ajax request made by the client:
new Ajax.Request( source, {
asynchronous: false,
method: 'post',
parameters: {content: RWSMLFile},
onSuccess: function(transport){
console.log(transport);
}.bind(this),
onFailure: (function ( transport ) {
ORYX.Log.error( "Sending RWSML file failed! Info: " + transport );
}).bind( this )
} );
The browser console displays the following error message:
POST http://localhost:8080/oryx/generategeddyjscode prototype-1.5.1.js:1044
Ajax.Request.Object.extend.request prototype-1.5.1.js:1044

When checking the Source tab, I encounter a Failed to load resource message after the last line of the following code snippet:
if (this.options.onCreate) this.options.onCreate(this.transport);
Ajax.Responders.dispatch('onCreate', this, this.transport);
this.transport.open(this.method.toUpperCase(), this.url,
this.options.asynchronous);
if (this.options.asynchronous)
setTimeout(function() { this.respondToReadyState(1) }.bind(this), 10);
this.transport.onreadystatechange = this.onStateChange.bind(this);
this.setRequestHeaders();
this.body = this.method == 'post' ? (this.options.postBody || params) : null;
this.transport.send(this.body);
Looking for guidance on resolving this issue. Any suggestions?
