PDF parser not working in production environment - weblogic-10.x

Question

I have an application that generates some PDFs. That works in preproduction systems but not in production system. We deploy in weblogic 10.3.6, both environments are supposed to have the same configuration
We have received de OK to deploy a web-app after all functional test were made in a non productive environment. The issue is that the final PDF that the app has to create does not work in production (but in test environment, yes).
We are using:
<dependency>
<groupId>org.xhtmlrenderer</groupId>
<artifactId>core-renderer</artifactId>
<version>R8</version>
<scope>compile</scope>
</dependency>
public static void crearPDFHTML(String htmlPlantilla, OutputStream pdf)
throws Exception {
try
{
ITextRenderer renderer = new ITextRenderer();
//String plantillaLimpia = makeTidy(htmlPlantilla);
LOG.info("Antes de limpiar caracteres especiales");
String limpio = quitarCaracteresEspeciales(htmlPlantilla);
LOG.info("Antes de poner el documento en el render");
LOG.info(limpio);
renderer.setDocumentFromString(limpio);
LOG.info("antes del layout");
renderer.layout();//HERE FAILS IN PRODUCTIVE ENVIRONEMENT
LOG.info("antes de crear PDF");
renderer.createPDF(pdf);
LOG.info("PDF creado con éxito");
}catch(Throwable e)
{
e.printStackTrace();
throw new Exception(e);
}
}
If the web app works fine in pre environement, it is supposed to work the same in pro environement, and generates the PDF.

Well, finally the issue was solved. It's a quite strange situation, and I don't think this will help anyone, but....
The issue is that in DES and PRE (non- productive environements) you can take the images the PDF needs using two urls (http or https) and works with both well. But in PRO the security configuration does not allow Itext to ask for a image using http. It must use https
So that was all, just change URL configuration, the PDF works and all people is happy again.
Thanks for the answers and patience
