I know the folder names.

inputfile folder in fixed

within inputfile/XXXX/ , this forlder is dynamic but again within this folder
inputfile/XXXX/XXXX_Delete inputfile/XXXX/XXXX_Update inputfile/XXXX/XXXX_Create

this will be fixed. Inside this folders,file names are unknown

I am merging files using below snippet.

But I wat to merge in some specific order of folder. I have folder structure like below

inputfiles ----folder1 ----------folder1_delete ----------folder1_update ----------folder1_create ----folder2 ----------folder2_delete ----------folder2_update ----------folder2_create
I want to merge files like It should merge all files of inputfiles/folder1/folder1_create then folder1_update and then folder1_delete.

<project default="mergefile"> <target name="mergefile"> <merge tofile="merged.txt"> <sourcefiles> <fileset dir="inputfiles"></fileset> \\ path of inputfiles </sourcefiles> </merge> </target> <macrodef name="merge"> <attribute name="tofile"></attribute> <element name="sourcefiles"></element> <sequential> <tempfile property="temp.file" prefix="ant.merge." deleteonexit="true"></tempfile> <concat destfile="${temp.file}" fixlastline="true"> <sourcefiles></sourcefiles> </concat> <copy file="${temp.file}" tofile="@{tofile}"> </copy> </sequential> </macrodef> </project>

I have a string like this TESTAPP_B_ABCD_JP_0_FILENAME I want the index of "ABCD" I have tried

select INSTR('TESTAPP_B_ABCD_JP_0_FILENAME', '_ABCD_') from dual;
It returns 10..It means it gives me index counting the characters

I want the output as 3 (Splitting the string TESTAPP(1),B(2),ABCD(3)).

Please guide.

I am migrating checkbox from struts1 to struts2 So I changed code from struts1

When i print i.e
<c:out value="${eDir}"></c:out>
..I get the value as true but same i put it in value attribute , it still doesn't have checked attribute
<s:checkbox theme="simple" style="border:0px" key="eDir" disabled="true" value="${eDir}"></s:checkbox>

What are the possible ways to convert below struts 1 code to migrate in struts 2. I know s:select tag but how to integrate c:foreach jstl in that?

<html:select property="activite" onchange="setActivite(form);" style="width:45px"> <html:option value=""><s:text name="form.date.jour" /></html:option> <c:forEach items="${jour}" var="varJour"> <c:if test="${not (varJour eq form.activite)}"> <option value="<c:out value="${varJour}"/>"><c:out value="${varJour}"/></option> </c:if> <c:if test="${varJour eq rechercheUtilisateurForm.jourFinActivite}"> <option selected value="<c:out value="${form.jactivite}"/>"><c:out value="${form.jourFinActivite}"/></option> </c:if> </c:forEach> </html:select>

Below is the html tag multibox which i want to migrate it to struts 2

<html:multibox name="unitForm" property="eservices"> <bean:write name="service"/> </html:multibox>
as it is checkbox so thought of using simple checkbox which is in the iterator so i used below code

<s:checkbox theme="simple" name="unitForm.eservices"></s:checkbox> in action
String[] toArray = new String[selectedadminVOs.size()]; unitForm.setEservices(selectedadminVOs.toArray(toArray));
stuck here,without or minimal changes in action code how can i migrate it to struts2

Now I tried with ImageWriter
Below is the updated code which reads array of bytes,processes the image(scaling) and returns the array of bytes.I have not yet included scaling code. but now I don't get any image and no exception as well.



public static byte[] resize(byte[] img) { byte[] outimage=null; try{ ByteArrayOutputStream baos = new ByteArrayOutputStream(30000); ImageOutputStream ios=null; try { ios = ImageIO.createImageOutputStream(baos); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } Iterator<ImageWriter> imageWriters = ImageIO.getImageWritersByFormatName("TIFF"); ImageWriter writer = (ImageWriter)imageWriters.next(); writer.setOutput(ios); // when I remoe this I get null pointer @writer.prepareWriteSequence(metadata); ImageWriteParam param = writer.getDefaultWriteParam(); param.setTilingMode(ImageWriteParam.MODE_DEFAULT); ImageReader reader=null; reader = getTiffImageReader(); ImageInputStream imageStream=null; imageStream = ImageIO.createImageInputStream(new ByteArrayInputStream(img)); if(reader!=null){ reader.setInput(imageStream); } int pages = reader.getNumImages(true); BufferedImage bufimage[] = new BufferedImage[pages]; ImageTypeSpecifier spec = ImageTypeSpecifier.createFromRenderedImage(reader.read(0)); javax.imageio.metadata.IIOMetadata metadata = writer.getDefaultImageMetadata(spec, param); writer.prepareWriteSequence(metadata); for(int i = 0; i < pages; i++) { bufimage[i]=reader.read(i); IIOImage iioImage = new IIOImage(bufimage[i], null, metadata); writer.writeToSequence(iioImage, param); writer.setOutput(ios); bufimage[i].flush(); writer.endWriteSequence(); } ByteArrayInputStream bai = new ByteArrayInputStream(baos.toByteArray()); outimage=baos.toByteArray(); ios.flush(); writer.dispose(); ios.close(); baos.close(); bai.close(); }catch(Exception e) { e.printStackTrace(); } return outimage; }

Tiff image total file size is 572 kb

Granted..Now every1's name is Happy

I wish I could go on a world tour.

Thank you Ulf Dittmer, I tried from the sample example but still getting single first page that too with OutOfMemory exception. Please find updated code below.

public static byte[] resize(byte[] image){ byte[] scaledimage=null; byte[] outimage=null; ImageReader reader=null; ByteArrayOutputStream os = new ByteArrayOutputStream(); ImageInputStream imageStream=null; try{ imageStream = ImageIO.createImageInputStream(new ByteArrayInputStream(image)); reader = getTiffImageReader(); if(reader!=null){ reader.setInput(imageStream); int pages = reader.getNumImages(true); for (int imageIndex = 0; imageIndex < pages; imageIndex++) { BufferedImage bufferedImage = reader.read(imageIndex); ByteArrayOutputStream buffer = new ByteArrayOutputStream(); ImageIO.write(bufferedImage, "TIFF", buffer); byte[] byarray=buffer.toByteArray(); scaledimage=scale(byarray,800,800); os.write(scaledimage, 0, scaledimage.length); buffer.close(); } outimage=os.toByteArray(); } } catch(Exception e) { e.printStackTrace(); } finally{ reader.dispose(); try { imageStream.close(); } catch (IOException e) { e.printStackTrace(); } try { os.close(); } catch (IOException e) { e.printStackTrace(); } } return outimage; } private static ImageReader getTiffImageReader() { Iterator<ImageReader> imageReaders = ImageIO.getImageReadersByFormatName("TIFF"); if (!imageReaders.hasNext()) { throw new UnsupportedOperationException("No TIFF Reader found!"); } return imageReaders.next(); }

I want to change the height of multi page TIFF image so I am using below code snippet to scale it. But It returns just first page from the tiff file , I guess it converts it to JPEG image. How to retain all pages of the file??

public static byte[] scale(byte[] fileData, int width, int height) { System.out.println("width:::"+width+"::::height:::"+height); ByteArrayInputStream in = new ByteArrayInputStream(fileData); ByteArrayOutputStream buffer=null; BufferedImage img=null; BufferedImage imageBuff=null; try { ImageInputStream imageStream = ImageIO.createImageInputStream(new ByteArrayInputStream(fileData)); java.util.Iterator<ImageReader> readers = ImageIO.getImageReaders(imageStream); while(readers.hasNext()) { ImageReader nextImageReader = readers.next(); nextImageReader.reset(); } img = ImageIO.read(in); if(height == 0) { height = (width * img.getHeight())/ img.getWidth(); } if(width == 0) { width = (height * img.getWidth())/ img.getHeight(); } Image scaledImage = img.getScaledInstance(width, height, Image.SCALE_SMOOTH); imageBuff = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB); imageBuff.getGraphics().drawImage(scaledImage, 0, 0, new Color(0,0,0), null); buffer = new ByteArrayOutputStream(); ImageIO.write(imageBuff, "TIF", buffer); } catch (IOException e) { e.printStackTrace(); } finally{ if(img!=null){ img.flush(); img=null; } if(imageBuff!=null){ imageBuff.flush(); imageBuff=null; } if(buffer!=null){ try { buffer.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } if(in!=null){ try { in.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } return buffer.toByteArray(); }

public boolean convertToTiff(File tiffFile, BufferedImage image) { ImageOutputStream ios = null; ImageWriter writer = null; try { // find an appropriate writer Iterator it = ImageIO.getImageWritersByFormatName("TIF"); if (it.hasNext()) { writer = (ImageWriter) it.next(); } else { return false; } // setup writer ios = ImageIO.createImageOutputStream(tiffFile); writer.setOutput(ios); TIFFImageWriteParam writeParam = new TIFFImageWriteParam( Locale.ENGLISH); writeParam.setCompressionMode(ImageWriteParam.MODE_EXPLICIT); writeParam.setCompressionType("LZW"); // convert to an IIOImage IIOImage iioImage = new IIOImage(image, null, null); writer.write(null, iioImage, writeParam); } catch (IOException e) { e.printStackTrace(); return false; } return true; }



Using the above code to convert from jpeg to tiff.
I want to compress the image so using compression types from http://download.java.net/media/jai-imageio/javadoc/1.1/com/sun/media/imageio/plugins/tiff/TIFFImageWriteParam.html

Original image(jpg) --->64kb LZW ---gives--->106kb JPEG---->177kb deflate--->doesn't work


Is there any other compression type or way which can give me more smaller or same size as that of original image?

I have tried this but got only blank spane without underline

<h:outputText style="font-weight:bold;text-decoration:underline" rendered="#{declarationBB.deaclarationOpr.declarationDetailsobj.productName == null}" value=" " />

I have created pdf using IText library

I want to highlight the DisplayTag's row which has value `'Total'` for this I was trying through javascript but I am uable to do that .Below is the snippet which I am using.Please guide.

I am getting the alert when there is Total in 2nd column but it does not get highlighted.

How to highlight a particular row which has value `Total` in 2nd column?
