    <p>I'm running into problems using AWT classes on OSX (10.5.8) with Java 6 (1.6.0_17 JVM: 14.3-b01-101). Trying to load java.awt.Dimension the code just freezes, this happens in Eclipse or from the command line. Anyone experiencing same problems ? The class is used by JAI in the following code: </p> <pre><code>public static byte[] resizeAsJPG(byte[] imageContent, double scale, float outputQuality) throws IllegalArgumentException, ImageOperationException { if (scale &lt;= 0) { throw new IllegalArgumentException("scale must be a positive number"); } if (outputQuality &lt;= 0 || outputQuality &gt; 1.0F) { throw new IllegalArgumentException("outputQuality must be between 0 and 1"); } try { // Fetch input image to seekable stream RenderedOp originalImage = getRenderedOp(imageContent); ((OpImage) originalImage.getRendering()).setTileCache(null); // Set scale parameters ParameterBlock saclingParams = new ParameterBlock(); saclingParams.addSource(originalImage); // The source image saclingParams.add(scale); // The xScale saclingParams.add(scale); // The yScale saclingParams.add(0.0); // The x translation saclingParams.add(0.0); // The y translation // RenderingHints renderingHints = new RenderingHints(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY); Map&lt;RenderingHints.Key, Object&gt; renderingHints = new HashMap&lt;RenderingHints.Key, Object&gt;(); renderingHints.put(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY); renderingHints.put(RenderingHints.KEY_ALPHA_INTERPOLATION, RenderingHints.VALUE_ALPHA_INTERPOLATION_QUALITY); renderingHints.put(RenderingHints.KEY_COLOR_RENDERING, RenderingHints.VALUE_COLOR_RENDER_QUALITY); renderingHints.put(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON); // Scale using sub-sampling average which provides much better quality than bicubic interpolation RenderedOp scaledImage = JAI.create("SubsampleAverage", saclingParams, new RenderingHints(renderingHints)); // Encode scaled image as JPEG JPEGEncodeParam encodeParam = new JPEGEncodeParam(); encodeParam.setQuality(outputQuality); // Since we scale height and width (don't take into account the quality) int outputSizeEstimate = (int) (imageContent.length * scale * scale); ByteArrayOutputStream outputStream = new ByteArrayOutputStream(outputSizeEstimate); ImageEncoder encoder = ImageCodec.createImageEncoder("JPEG", outputStream, encodeParam); encoder.encode(scaledImage); return outputStream.toByteArray(); } catch (Exception e) { throw new ImageOperationException(e.getMessage(), e); } </code></pre> <p>}</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
