I need an example of usign FormEngine. To be more especific....
I'm executing code below - but there’s no forms found in my BAR file :(
The BAR file was exported from Flowable Modeler and it contains one form and one process and app. Maybe there's other way to deploy and obtain forms...?
RepositoryService repositoryService = processEngine.getRepositoryService();
FormRepositoryService formRepositoryService = formEngine.getFormRepositoryService();
File file = new File(path);
ZipInputStream inputStream = new ZipInputStream(new FileInputStream(path));
String idDeployParent = repositoryService.createDeployment()
.name(file.getName())
.addZipInputStream(inputStream)
.deploy()
.getId();
DeploymentEntity deploymentEntity = (DeploymentEntity) repositoryService.createDeploymentQuery().list().get(0);
formRepositoryService.createDeployment()
.name(file.getName())
.parentDeploymentId(idDeployParent)
.deploy();
System.out.println(" FORMS FOUND: " + formRepositoryService.createFormDefinitionQuery().list().size());

I am trying to create a shared folder in a dropbox account, from a Java desktop application by using the dropbox-core-sdk-2.0-beta-4, with the code below, but I am getting these exceptions:
java.lang.NoSuchMethodError: com.dropbox.core.json.JsonWriter.writeFields(Ljava/lang/Object;Lcom/fasterxml/jack son/core/JsonGenerator;)V

My code is the following:
DbxRequestConfig dbxRequestConfig = new DbxRequestConfig("test/1.0", Locale.getDefault().toString());
DbxClientV2 dbxClient = new DbxClientV2(dbxRequestConfig, my_access_token);
FolderMetadata md = dbxClient.files.createFolder("/test");
ArrayList<AddMember> list = new ArrayList();
DbxSharing.AddMember a1 = new DbxSharing.AddMember(DbxSharing.MemberSelector.email("xxxxxx#gmail.com"),
DbxSharing.AccessLevel.editor);
list.add(a1);
dbxClient.sharing.addFolderMember(md.parentSharedFolderId, list);
My code is heating at:
FolderMetadata md = dbxClient.files.createFolder("/test");
I have already search for any solution to create a shared folder and add a member to it, but I am not finding anything useful to my case.
Could anyone tell me what I am doing wrong?
scala code :
val file = new File(path + name)
val raf = new RandomAccessFile(file, "r")
val channel = raf.getChannel()
val buf = channel.map(FileChannel.MapMode.READ_ONLY, 0, channel.size())
val pdffile = new PDFFile(buf) // line 5
here, file is referring to pdf file. path is the address of pdf file and name is name of file.
In normal case, it executes fine, but in some pdf files, it throws error in line 5 as :
com.sun.pdfview.PDFParseException: Expected 'xref' at start of table
at com.sun.pdfview.PDFFile.readTrailer(PDFFile.java:974) ~[pdf-renderer-1.0.5.jar:na]

I think this pdf file has some problem with its format or content. When i made another pdf file using save as with this pdf file and used that new created pdf file, it worked fine.
So how can i resolve this problem so that whetehr i use proper file or bad file, my code should work fine.
EDIT
I found the following in the com/sun/pdfview/PDFFile.java description
#throws PDFParseException if the document appears to be malformed, or
its features are unsupported

I'm developing an eclipse plug-in and I need to traverse a directory and whole content of the directory. I found the method which reads a file in plug-in (bundleresource) as InputStream.
InputStream stream = Activator.class.getResourceAsStream("/dir1/dir2/file.ext");
this method works for files only. I need a way to read directories, list subdirectories and files like File.io.
Thanks.
Do you want to read a resource directory of your plugin? Otherwise you have to traverse a directory and open one stream per file:
String path = "c:\\temp\\";
File directory = new File(path);
if (directory.isDirectory()) {
String[] list = directory.list();
for (String entry : list) {
String absolutePath = path + entry;
System.out.println("processing " + absolutePath);
File file = new File(absolutePath);
if (file.isFile()) {
FileInputStream stream = new FileInputStream(file);
// use stream
stream.close();
}
}
}
If you want to traverse subdirectories as well you should wrap this into a recursive method, check if file is a directory and call the recursive method in this case.
I've got an Excel file that's built using OpenXML 2 and I want to send it as an email attachment. e.g.
System.IO.MemoryStream stream = new System.IO.MemoryStream();
SpreadsheetDocument package = SpreadsheetDocument.Create(stream, SpreadsheetDocumentType.Workbook))
AddParts(package); //created using document reflector
Saving the spreadsheet to a temp file using
stream.WriteTo(new System.IO.FileStream(#"c:\test.xlsx", System.IO.FileMode.Create));
works fine. But trying to send the stream directly as an email attachment fails - just get an empty file attached to the email when I do
System.Net.Mail.Attachment file = new System.Net.Mail.Attachment(stream, "MobileBill.xlsx", "application/vnd.ms-excel");
Anbody know how to do this?
Ok, I got this working, though through some effort. To create the stream:
MemoryStream stream = new MemoryStream();
using (SpreadsheetDocument package = SpreadsheetDocument.Create(stream, SpreadsheetDocumentType.Workbook))
{
Excel.CreateSpreadsheet(package, Excel_Methods.CreateSpotQuoteOut(), true);
}
stream.Seek(0, SeekOrigin.Begin);
System.Net.Mail.Attachment attach = new System.Net.Mail.Attachment(stream, "spreadsheet.xlsx");
attach.ContentDisposition.CreationDate = DateTime.Now;
attach.ContentDisposition.ModificationDate = DateTime.Now;
attach.ContentDisposition.Inline = false;
attach.ContentDisposition.Size = stream.Length;
attach.ContentType.MediaType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
Also, I found that mine were not being sent right after I created them, and the reason for that is "standalone=yes" was not being added to the xml declaration of all the pages, so in my AddParts function, after adding the parts, I passed them into this function:
private static void AddXMLStandalone(OpenXmlPart part)
{
System.IO.StreamWriter writer = new System.IO.StreamWriter(part.GetStream());
XmlDocument doc = new XmlDocument();
doc.Load(part.GetStream());
doc.InnerXml = doc.InnerXml.Substring(doc.InnerXml.IndexOf("?>") + 2);
doc.InnerXml = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?>" + doc.InnerXml;
part.GetStream().SetLength(doc.InnerXml.Length);
doc.Save(writer);
writer.Flush();
writer.Close();
}
Good luck!
do this:
System.Net.Mail.Attachment file = new System.Net.Mail.Attachment(new MemoryStream(stream.ToArray()), "MobileBill.xlsx", "application/vnd.ms-excel");
Apparently the memory stream doesn't get flushed or something
For your "content unreadable" problem, make sure to Save() your Workbooks and Worksheets and enclose your SpreadsheetDocument in a using statement to ensure all packages and zipped streams are flushed, closed and so on.
System.IO.MemoryStream stream = new System.IO.MemoryStream();
using (SpreadsheetDocument package = SpreadsheetDocument.Create(stream, SpreadsheetDocumentType.Workbook)))
{
AddParts(package);
//Save if AddParts hasn't done it
}
System.Net.Mail.Attachment file = ...
Thinking out load: could it be, that the Attachment class expects to read from the current possition in the provided stream? If this is the case, you would probably have to "seek" back to the beginning of the stream, before feeding it to the Attachment constructor:
AddParts(package); //created using document reflector
stream.Seek(0, SeekOrigin.Begin);
System.Net.Mail.Attachment file = new System.Net.Mail.Attachment(stream, "MobileBill.xlsx", "application/vnd.ms-excel");
I'm trying to copy a custom object from a RDC window into host (my local) machine. It fails.
Here's the code that i'm using to 1) copy and 2) paste:
1) Remote (client running on Windows XP accessed via RDC):
//copy entry
IDataObject ido = new DataObject();
XmlSerializer x = new XmlSerializer(typeof(EntryForClipboard));
StringWriter sw = new StringWriter();
x.Serialize(sw, new EntryForClipboard(entry));
ido.SetData(typeof(EntryForClipboard).FullName, sw.ToString());
Clipboard.SetDataObject(ido, true);
2) Local (client running on local Windows XP x64 workstation):
//paste entry
IDataObject ido = Clipboard.GetDataObject();
DataFormats.Format cdf = DataFormats.GetFormat(typeof(EntryForClipboard).FullName);
if (ido.GetDataPresent(cdf.Name)) //<- this always returns false
{
//can never get here!
XmlSerializer x = new XmlSerializer(typeof(EntryForClipboard));
string xml = (string)ido.GetData(cdf.Name);
StringReader sr = new StringReader(xml);
EntryForClipboard data = (EntryForClipboard)x.Deserialize(sr);
}
It works perfectly on the same machine though.
Any hints?
There are a couple of things you could look into:
Are you sure the serialization of the object truely converts it into XML? Perhaps the outputted XML have references to your memory space? Try looking at the text of the XML to see.
If you really have a serialized XML version of the object, why not store the value as plain-vanilla text and not using typeof(EntryForClipboard) ? Something like:
XmlSerializer x = new XmlSerializer(typeof(EntryForClipboard));
StringWriter sw = new StringWriter();
x.Serialize(sw, new EntryForClipboard(entry));
Clipboard.SetText(sw.ToString(), TextDataFormat.UnicodeText);
And then, all you'd have to do in the client-program is check if the text in the clipboard can be de-serialized back into your object.
Ok, found what the issue was.
Custom format names get truncated to 16 characters when copying over RDC using custom format.
In the line
ido.SetData(typeof(EntryForClipboard).FullName, sw.ToString());
the format name was quite long.
When i was receiving the copied data on the host machine the formats available had my custom format, but truncated to 16 characters.
IDataObject ido = Clipboard.GetDataObject();
ido.GetFormats(); //used to see available formats.
So i just used a shorter format name:
//to copy
ido.SetData("MyFormat", sw.ToString());
...
//to paste
DataFormats.Format cdf = DataFormats.GetFormat("MyFormat");
if (ido.GetDataPresent(cdf.Name)) {
//this not works
...
