BackColor only appears in the Preview

[ayparraguirre]

Hello everyone,

I have a fabric report and I need to view a sample of each color shown.

I am coloring a TextField field, according to the hexadecimal value that is in the database.

In Text Field Expression, I use: "<style backcolor = '" + $ F {HEXA1} + "' forecolor = '" + $ F {HEXA1} + "'>" + $ F {HEXA1} + " </style> "

It is working in the Preview of IREPORT, but when I put it in the application (Java EE), the color does not appear and only shows the expression above.

In the code of the generated html page it looks like this: <td colspan = "9" style = "text-align: center;"> <span style = "color: #FFFFFF; background-color: #FFFFFF;"> & lt; style backcolor = '# 7E7CA8' </span> </td>

My call from ManagerBean is this:
// report call
DSReportReceitaCorSolic ds = new DSReportReceitaCorSolic(listareportenviocorcli);
InputStream arquivo = FacesContext.getCurrentInstance().getExternalContext().getResourceAsStream("/envio_amostra_cliente.jasper");
byte[] pdf = JasperRunManager.runReportToPdf(arquivo, null, ds);
HttpServletResponse res = (HttpServletResponse) FacesContext.getCurrentInstance().getExternalContext().getResponse();
res.setContentType("application/pdf");
res.setContentLength(pdf.length);
OutputStream out = res.getOutputStream();
out.write(pdf, 0, pdf.length);
out.flush();
out.close();
FacesContext.getCurrentInstance().responseComplete();

Does anyone know how to show the color, as in the preview of IREPORT? 
Thank you
