У меня есть приложение, которое генерирует некоторые PDF-файлы.Это работает в системах подготовки производства, но не в системе производства.Мы развертываем в weblogic 10.3.6, обе среды должны иметь одинаковую конфигурацию
Мы получили разрешение на развертывание веб-приложения после того, как все функциональные тесты были выполнены в непроизводительной среде.Проблема в том, что окончательный PDF-файл, который должно создать приложение, не работает в рабочей среде (но в тестовой среде - да).Мы используем:
<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);
}
}
Если веб-приложение отлично работает в предварительной среде, оно должно работать точно так же в профессиональной среде и генерирует PDF.
