I had an app that fills a form with itextg 5.5.0 and now it doesn´t work

Question

I have a problem beacuse I had an app that it was filling a form with itexg(5.5.0) and now Itdoesn´t work; I have tried update to the last version 5.5.1 with the other two librerys. Well with the old version I had this error:

05-30 12:57:56.554: E/dalvikvm(8633): Could not find class 'org.spongycastle.cert.X509CertificateHolder', referenced from method com.itextpdf.text.pdf.PdfReader.readDecryptedDocObj

With the lasted version: the pdf was generated but It doesn't fill the form and I have diferenet messages:

iTextG has a dependency on SpongyCastle. Did you include the correct version of SpongyCastle in your APK? — Bruno Lowagie, May 30 '14 at 14:24
I have included the two diferents librarys that it told on web page. Will Ihave to included a spongycastle to?where can I donwload a spongecastle for android? Thanks — user3690964, May 31 '14 at 11:31

By the way: which web page are you referring to? I just checked and I see that SpongyCastle is listed as required: http://itextpdf.com/product/itextg — Bruno Lowagie, May 31 '14 at 11:37
I have included this two diferents librarys : scprov-jdk15on and scpkix-jdk15o with the lasted version I think and I haven't the warnings now but I can't fill the form because it doesn't know the fields. In may case when made the inicializate of acrofields it doesn't find any field — user3690964, May 31 '14 at 11:51
Those are completely different questions: (1) does your PDF have fields? (2) Are those fields AcroFields or XFA fields? (3) If AcroFields: how come you don't know the names of the fields? **Also important:** please use proper language. *May* is a month, which is not the same as *my*, but more importantly *when made the inicializate of acrofields* doesn't make any sense. Can you explain in code what you mean by that? — Bruno Lowagie, May 31 '14 at 11:54
Yes the pdf has fields. It's the same document that i filled with the previous version. In my case is a easy doccument becasue it's a prototipe of function for oteher app. the pdf has 3 diferents fields Name, Surname and Date(all fields are in spanish); the pdf was made with acrobat pro and it has a form fields. — user3690964, May 31 '14 at 12:10
The question remains: AcroForm technology or XFA technology? Also: your comments are no longer related to your original question which was about `Could not find class 'org.spongycastle.cert.X509CertificateHolder'`. Create a new question and avoid using the words "doesn't work". Tell people what the desired output is and what you got instead: http://lowagie.com/doesntwork — Bruno Lowagie, May 31 '14 at 12:12
It's an AcroFrom technology. Thanks for your help and I will open other question about it. — user3690964, May 31 '14 at 12:25

I fixed this issue. By importing all 4 jar.

core (jar) - Core lightweight API
prov (jar) - JCE provider (requires core)
pkix (jar) - PKIX, CMS, EAC, TSP, PKCS, OCSP, CMP, and CRMF APIs (requires prov)
pg (jar) - OpenPGP API (requires prov)

For details please find http://rtyley.github.io/spongycastle/#downloads

I had an app that fills a form with itextg 5.5.0 and now it doesn´t work
