Hello,

does new library supports some kind of optimization, which offers similar functionality to PDF reduce file size function in Adobe Acrobat Pro ?

edit: I use PDFSmartCopy to merge multiple PDFs, however I wonder if there is something which can compress the output file.


Many thanks
Jakub

Fantastic ! Thanks Mark

Hi Bruno

I know that merging pdfs is possible using iText, for example using PdfCopy class. However I got 100ish pdfs based on the one template ( they got the same graphics, just different wording )

Is it possible, during merging, to copy images once and then use references to those images later on ?

ah sorry should be "any corner"

for example I would like to place Textfield 10 mm left from the left margin of the page or xx mm from other element, something like positioning in CSS ?

Hi Bruno

First of all I would like to thank you for a great book and library ! They do a great job!

I have couple of question regarding iText.

1. iText Book. Do you have a chapter where you explain how to create a PDF Portfolio (portable collection) ?
I had problem in the past printing big pdfs ( like 600 pages/ 300 MB), printer couldn't handle that resulting blank pages in the middle of the print. So I use PDF portfolio to print PDF forms;

2. You have a chapter about using HTML in PDF, does your library handle that by itself or xhtmlrenderer is needed ?

3. Is it possible to position pdf form elements by defining tany corner ( like (x,y) in mm ) ?


Cheers

It's hard to tell, so if you could pack your grails-app, put somewhere, and provide a link ( through forum or PM ), then I could check it for you.

--edit
I reviewed your files and couple of things you could improve.

1. Put 3 classes created by Acegi plugin into package 'gameaddict' or 'security' or even 'gameaddict.security' ( yours grail app ) so you wont have problems with finding them later. You can use a command like
grails create-auth-domains gameaddict.security.Person gameaddict.security.Authority gameaddict. security.Requestmap

2. to get info in controller about current user, add authenticateSerive and then use userDomain() method. eg.
def authenticateService ... def save = { def recenzjaInstance = new Recenzja(params) def person = authenticateService.userDomain() if (person) { recenzjaInstance.autor = person // jesli nie bedzie autora to ci nie zapisze obiektu } if (recenzjaInstance.save(flush: true)) { flash.message = "${message(code: 'default.created.message', args: [message(code: 'recenzja.label', default: 'Recenzja'), recenzjaInstance.id])}" redirect(action: "show", id: recenzjaInstance.id) } else { render(view: "create", model: [recenzjaInstance: recenzjaInstance, autor: person.id]) } }

I hope it helps

hi it looks like your structure is a bit messed up.

try to sort out your folders like :
<appname> grails-app conf controllers <appname or other package name> ReviewController.groovy domain <appname or other package name> Review.groovy Person.groovy lib out scripts src groovy <some ohter packages> SomeClass.groovy target test ...

if you have a domain class put it in grails-app/domain/<package> like Review and Person .
If you want to have some classes which are not domain classes put them in src/groovy/<package>/

then you can import them in grails using import <package-name>.<className>

Regards

Hi

if you use grails version 1.3.1 or newer then your domain classes will be in package named by your application. It is always better to use packages

check packages and if controller and domain class are in different packages use import.

If you match person witch acegi user by username, then you can find person using GORM
def person = Person.findByUsername(usernameFromAcegi)

BTW you can get information from acegi anytime so there is no need to pass user information, just find a proper person before you save a review

I will try to make an example:
// review controller def showForm = { def person = ... // get a person object from Acegi def reviewInstance = new Review() reviewInstance.properties = params [ reviewInstance: reviewInstance, personId : person.id ] } def saveReviewForm = { // load a person def person = Person.get(params.personId) // do all the rest with review Form ... }

and in view

<g:jiddenField name="personId" value="$personId" />

in this case you save the bandwidth, you send only small int instead of the serialized object.

Hi Karol,

What about using hidden field for person id and then in submit action load the proper user object which you can use later in your review.

If you want to send the object through the form you will have to serialize and deserialize after.However this approach is not so secure, because user can modify the object before submission.

Hi,

I think you might read your error message wrongly.

The actual error is : The column name borrowedby was not found in this ResultSet.

Look at http://www.regular-expressions.info/quickstart.html

a|b means to look for a or b

Great,

Is SpringSource involved in Griffon development ? ( they got Grails )
