    <p>I found out that by using apache xml-rpc implementation on both client and server it is possible to throw custom exceptions from the server and receive them on the client. Something just needs to be added to the server and client configuration.</p> <p>Server:</p> <pre><code>WebServer server = new WebServer(80); XmlRpcServer xmlRpcServer = server.getXmlRpcServer(); PropertyHandlerMapping phm = new PropertyHandlerMapping(); phm.addHandler("test", JavaServer.class); xmlRpcServer.setHandlerMapping(phm); XmlRpcServerConfigImpl serverConfig = (XmlRpcServerConfigImpl) xmlRpcServer.getConfig(); serverConfig.setEnabledForExceptions(true); serverConfig.setEnabledForExtensions(true); //Add this line server.start(); </code></pre> <p>Client:</p> <pre><code>XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl(); try { config.setServerURL(new URL("http://localhost:80")); config.setEnabledForExceptions(true); config.setEnabledForExtensions(true); //Add this line XmlRpcClient client = new XmlRpcClient(); client.setConfig(config); Object[] params = new Object[] { new Integer(11), new Integer(3), }; Integer result = (Integer) client.execute(config,"test.sum", params); System.out.println("Results " + result); } catch (XmlRpcException exception) { System.out.println(exception.getMessage()); Throwable cause = exception.getCause(); if(cause != null) { if(cause instanceof MyException) { System.out.println(((MyException)cause).getMessage()); } else { System.out.println("Cause not instance of Exception."); } } else { System.out.println("Cause was null."); } } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); </code></pre> <p>Then everything works as expected.</p>

    1. COCustom exceptions aren't part of the xml-rpc standard. That's why apache's implementation offers this possibility as an extension to the actually protocol. Thus you have to enable extensions in apache xml-rpc and it only works with both client and server using it.

    2. COHi Otto, thanks for the comment and yes, indeed I found that by enabling extensions I could do what I wanted.

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.
