fos | FOG Operating System

You should instantiate the fos-rest View manually and add a Context. On that Context you can set the serialization groups at runtime by evaluating the users roles.

Something like this should work:

The whole problem goes away when the text-replacement works correctly.

The problem here is how Word stores texts in different text runs. Not only different formatting splits text in different text runs, also marking grammar and spelling check problems do and multiple other things. So one can impossible predict how a text gets split into text runs when typed in Word. That's why your text-replacement approach is not good.

Apache POI provides TextSegment to solve those kind of problems. And using current apache poi 5.2.0 this also seems to work correctly. Former versions had have bugs in XWPFParagraph.searchText - see Apache POI: ${my_placeholder} is treated as three different runs for a workaround.

Using TextSegment one can determine the begin and end of a seached text and so doing the text-replacement better.

Following example should show this.

My Reference.docx looks like so:

There ${firstname}, ${lastname} and ${address} in head are bookmarked as firstname. lastname and address. And their occurences in text are references as { REF firstname } , { REF lastname} and { REF address}

After running following code:

The problem is you used a DataOutputStream. That is unnecessary here, just write to the FileOutputStream. The 0x05 0x01 is an object header that is meaningful only when the output is read later by a DataInputStream.

The culprit is this: XWPFDocument doc = new XWPFDocument(OPCPackage.open(source));. And specially this: OPCPackage.open(source).

While static OPCPackage open(java.lang.String path) the OPCPackage gets opened from the underlying file of file path path with read/write permission. Additional it stays directly connected to the underlying file. This saves some memory but has disadvantages too, as you will see now.

All changes in XWPFDocument are made in that OPCPackage but in random access memory first.

While calling doc.write, which calls POIXMLDocument.write(java.io.OutputStream stream), at first the underlying OPCPackage gets updated. Then the changed OPCPackage gets saved in the destination document through the given OutputStream stream. So without calling doc.write nothing gets changed in files but stays in random access memory only.

Then while doc.close() gets called also OPCPackage.close gets called. This closes the open, writable package and saves its content. And since the OPCPackage is directly connected to the underlying file, it saves the content into that file. That's why the changes are also written to the source document.

This should explain your observations.

The XWPFDocument also provides constructor XWPFDocument(java.io.InputStream is). This internally calls OPCPackage.open(java.io.InputStream in). And this opens the OPCPackage from the InputStream. The OPCPackage then is in random access memory only and is independent form the source file. That uses some more memory as the whole OPCPackage needs to be in random access memory but OPCPackage.close will not lead to changes in source file.

So what I would do is:

Yes that is possible.

Your image is in byte [] buffer = ...

You can make a Bitmap instance with BitmapFactory.decodeByteArray().

After that assign bitmap to an ImageView.

This answer essentially is a more detailed version of the comments, essentially finding that what you want to do is not possible.

You ask for a way to

Certify Document when Approval Signature exist

According to the current PDF specification:

Thus, you cannot validly add a certification signature to a PDF which already has approval signatures.

(This does not automatically mean that all validators will detect the issue if you add a certification signature after approval signatures, let alone correctly display the cause. Many validators only do a subset of the checks that strictly speaking are necessary...)

More question if the certification signature come first then next is approval like 3 signature approval, can the last the certification setMDPPermission with 1 ? so at the end the document can't add more approval signature

setMDPPermission adds a DocMDP transform to the signature, and such a transform makes the signature a certification signature. Thus, using this method when signing a document that already has an approval signature, will create an invalid PDF or fail entirely.

You can lock a PDF document with an approval signature, though, if you add a Lock dictionary to the signature field with a P entry of 1. Beware, though, this is a ISO 32000-2 feature originally introduced as a feature of an Adobe Extension to ISO 32000-1. Not all PDF viewers support ISO 32000-2 yet, so some viewers may not respect this entry.

For usage using Microsoft Excel it is as simple as adding a pivot source to the chart. After that Excel renders the chart from the given pivot table.

In Office Open XML (XSSF) the pivot source is given by a PivotSource element having the qualified name of the pivot table set as name. Qualified name is: [workbookName]worksheetName!pivotTableName.

This is workbook name in square brackets followed by worksheet name followed by an exclamation mark followed by the pivot table name.

In code this would look as so:

First lets take a look at getting write permissions for an existing image. Please note that the photopath does not necessarily exist yet but should point to the location you want your file to be saved.

The IIB is copied into all constructors of a class by the compiler and it is executed as the last statement of each constructor. FileInputStream#readObject however, does not call any constructors of serialized classes that implement Serializable. Only the default constructor of parent classes that do not implement Serializable are called.

Since your property stackOverflow is transient it is not serialized, and since the constructor of StackOverflow is not called during deserialization, the property is not reinitialized.

If you need to do some initialization while deserialization you can do this by implementing `Serializable#readObject)
