Hello teodor, this font.jar contains tthe two TT-fonts (vcarial.ttf and vcarialbd.ttf) we are using with JR: <reportFont name ="HeaderFont" isDefault ="false" fontName ="VCArial" size ="8" isBold ="true" isItalic ="false" isUnderline ="false" isStrikeThrough ="false" pdfFontName ="vcarialbd.ttf" pdfEncoding ="Cp1252" isPdfEmbedded ="true"/> The fonts are initialized by: final InputStream isArial = getClass().getResourceAsStream("/vcarial.ttf"); final InputStream isArialBold = getClass().getResourceAsStream("/vcarialbd.ttf"); Font.createFont(Font.TRUETYPE_FONT, isArial); Font.createFont(Font.TRUETYPE_FONT, isArialBold); isArial.close(); isArialBold.close(); This solution indeed solved the font problems we had that time, so i'm quite sure it always worked as intended. It just happened with the Websphere upgrade that a similar (above mentioned) font problem occured, and i have no further idea to solve it.
