ImageMagick darkening Grayscale PNGs

When converting or mogrify-ing images I’ve noticed grayscale PNG files are far darker than originals – mid-grays become almost black. It turns out ImageMagick tries to set to PNG8 based on image content even if the file was previously PNG24 or PNG32. This conversion is trigged by both convert and mogrify, e.g. image resizing with… Continue reading ImageMagick darkening Grayscale PNGs

Waiting for EBSs/WARs in JBoss to deploy using gradle / twiddle

Some home development for an issue at work… Often integration tests fail because the ESBs/WARs fail to deploy, we’d like early warning of this. The ESBs/WARs are deployed into a JBoss instance using gradle. The deployment gradle script can be enhanced with the following to use – a built in JBoss JMX client to… Continue reading Waiting for EBSs/WARs in JBoss to deploy using gradle / twiddle

Unmarshalling JAXB entities from SOAP wrappers

Extracting JAXB entities from inside SOAP wrappers can be done without string-chopping using standard APIs. Example: using standard API. String example = "<soapenv:Envelope xmlns:soapenv=\"\"><soapenv:Header /><soapenv:Body><ns2:farm xmlns:ns2=\"\"><horse height=\"123\" name=\"glue factory\"/></ns2:farm></soapenv:Body></soapenv:Envelope>"; SOAPMessage message = MessageFactory.newInstance().createMessage(null, new ByteArrayInputStream(example.getBytes())); Unmarshaller unmarshaller = JAXBContext.newInstance(Farm.class).createUnmarshaller(); Farm farm = (Farm)unmarshaller.unmarshal(message.getSOAPBody().extractContentAsDocument()); Anti-example seen in the wild: string chopping / regex String example =… Continue reading Unmarshalling JAXB entities from SOAP wrappers

Marshalling JAXB entities into SOAP wrappers

SOAP envelopes can be added to existing org.w3c.dom.Document or JAXB instances easily. Farm farm = new Farm(); farm.getHorse().add(new Horse()); farm.getHorse().get(0).setName("glue factory"); farm.getHorse().get(0).setHeight(BigInteger.valueOf(123)); Example: using standard API Document document = DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument(); Marshaller marshaller = JAXBContext.newInstance(Farm.class).createMarshaller(); marshaller.marshal(farm, document); SOAPMessage soapMessage = MessageFactory.newInstance().createMessage(); soapMessage.getSOAPBody().addDocument(document); ByteArrayOutputStream outputStream = new ByteArrayOutputStream(); soapMessage.writeTo(outputStream); String output = new String(outputStream.toByteArray()); Anti-example seen in… Continue reading Marshalling JAXB entities into SOAP wrappers
