But this code don't works:     Method setBI = *sanselan1*.getMethod(             "writeImage",             new Class[]{ BufferedImage.class, File.class, ImageFormat.class, Map.class }         );     setBI.invoke(null, new Object[]{ image, imageOut, ImageFormat.IMAGE_FORMAT_PNG, null }); I get an error: java.lang.NoSuchMethodException: org.apache.sanselan.Sanselan.writeImage(java.awt.image.BufferedImage, java.io.File, org.apache.sanselan.ImageFormat, java.util.Map) But if I using standart class loader:     Class<?> *sanselan2* = Class.forName("org.apache.sanselan.Sanselan");     //...     Method setBI = *sanselan2*.getMethod(             "writeImage",             new Class[]{ BufferedImage.class, File.class, ImageFormat.class, Map.class }         );     setBI.invoke(null, new Object[]{ image, imageOut, ImageFormat.IMAGE_FORMAT_PNG, null }); Everithing works fine! It meanse, that org.apache.sanselan.Sanselan have method writeImage and I correctly called it. But if I using javassist.gluonj.util.Loader I have an exception: NoSuchMethodException. What is a problem? -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/731467#731467] Start a new discussion in Javassist at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
