I'm working on some workflow automation that takes files from an external
process and loads them via curl.
The following code is working, but it uses a private class
com.webobjects.appserver._private.WOInputStreamData to grab the file contents.
This makes me think there is probably a better, more WOnderful way of doing
this, so if anybody sees problems or easier ways to do what I have here, I
would welcome any suggestions.
This is from a small, scratch application where the Center has many StubFile
(which has an ERAttachment named fileAttachment)
public WOActionResults fileUploadAction() {
WOResponse res = new WOResponse();
if (!this.request().formValues().containsKey("centerkey") ||
!this.request().formValues().containsKey("fileToBeUploaded")) {
res.setStatus(400);
res.appendContentString("<html><head><title>ERROR</title></head><body><h1>Missing
Parameters</h1></body></html");
return res;
}
Integer ck = new
Integer(this.request().formValueForKey("centerkey").toString());
logger.debug("looking for center with key " + ck);
WOInputStreamData wois = (WOInputStreamData)
this.request().formValueForKey("fileToBeUploaded");
String mimeType = (String)
this.request().formValueForKey("mimetype");
EOEditingContext ec = ERXEC.newEditingContext();
Center c = (Center) EOUtilities.objectWithPrimaryKeyValue(ec,
Center.ENTITY_NAME, ck);
logger.debug("found " + c.name() + " for centerkey " + ck);
StubFile f = (StubFile) EOUtilities.createAndInsertInstance(ec,
StubFile.ENTITY_NAME);
f.setCenterId(ck);
f.setCenterRelationship(c);
f.setFilename((String)
this.request().formValueForKey("filename"));
f.setTitle((String) this.request().formValueForKey("title"));
try {
NSData fileData = new NSData(wois.bytes());
File up;
up = File.createTempFile("curlupload", "vaws");
FileOutputStream uploadingFile = new
FileOutputStream(up);
fileData.writeToStream(uploadingFile);
uploadingFile.close();
ERAttachment attachment =
ERAttachmentProcessor.processorForType("file").process(ec, up, null, mimeType,
"StubFile.fileAttachment", null);
f.setFileAttachmentRelationship(attachment);
ec.saveChanges();
} catch (IOException e) {
e.printStackTrace();
res.setStatus(501);
res.appendContentString("<html><head><title>ERROR</title></head><body><h1>File
Error:</h1><pre>" + e.getMessage() + "</pre></body></html");
return res;
}
res.setStatus(201);
res.appendContentString("<html><head><title>Success</title></head><body><h1>attachment
loaded</h1></body></html");
return res;
}
