An Easy Way to Test HTTP Requests During Development


Web and web services developers often need to send HTTP requests – whether for testing APIs, testing REST and SOAP web services, or managing web sites.

XMLSpy now makes it easy to send and receive HTTP requests directly in the XML editor during development with a new HTTP Window and WADL/WSDL Import Wizard.

Images, Icons, and Tool Buttons in Mobile Apps


We have written previously about Integrating APIs and Mobile Apps to create a rich and entertaining user experience. Since publishing our previous post, we continued to enhance the GPS demo app with additional API support to get current weather conditions and scheduled events nearby.

One challenge with offering all this functionality on a small mobile screen is to provide users with a clear, consistent, and easy to use navigation scheme across all views in the app.

Applying icon images as tool buttons in mobile apps can create a stylish and graceful navigation menu, especially if the icons are chosen based on recognizable and commonly-agreed conventions. For instance, an arrow pointing left often indicates go back, and a floppy disk icon frequently represents save data, even when the ultimate destination might not be a new file nor a disk.

In this post we will describe how to use image icons to build cross-platform navigation menus with tool buttons in mobile apps using MobileTogether.

Creating and Deleting Database Records with MobileTogether


Creating, deleting, and validating records is an essential bit of functionality in all data driven apps. By using MobileTogether Designer, developers can produce cross platform apps capable of handling these functions and more in record time.

The video tutorial below expands upon the concepts introduced in previous videos. It covers the steps required to add functionality for creation, deletion, and data validation to your mobile app.

If you’re new to MobileTogether Designer, please take a moment to view the MobileTogether Demos page where we have provided links to additional video tutorials and demo apps.

Integrating APIs and Mobile Apps


Busy mobile users on the go prefer apps that are convenient and efficient. MobileTogether provides developers with features to seamlessly integrate APIs and mobile apps to combine mobile device functionality with up-to-date information from external sources. This empowers developers to create custom cross-platform native apps that provide a rich and entertaining end-user experience.

Public APIs are a great source of external data to enhance almost any custom mobile app. Developers can combine information from multiple APIs to provide users with better information, faster, in an elegant, integrated package.

APIs are available for almost any kind of information your mobile app may need, from flight tracking to commodity or stock prices to tropical storm tracking.

In this post we’ll look at a GPS app that starts with mobile device geolocation functionality to answer the basic question, “Where am I?” then interfaces with APIs from Google and MapQuest to add a wealth of additional information. We’ll integrate a spatially-aware search engine to locate nearby points of interest as near as a quarter mile radius, all the way to pin-pointing the user’s location in a satellite photograph with a wide-angle view of an entire continent or more.

Retrieve and Modify Images with MobileTogether


Inevitably mobile developers will need to build an app that needs to interact with their users’ camera and gallery.  MobileTogether Designer makes this task easy by providing a set of controls that allow developers to add this functionality to apps in record time.  The video tutorial below is a continuation of our series aimed at working with databases in MobileTogether; it covers steps needed to solicit images and, if necessary, resize those images to fit a user’s device.

How to Debug XSLT and XQuery


Nothing’s more frustrating than getting unintended results from an XSLT or XQuery transformation and having to spend hours tracking down the issue – especially if you’ve inherited the project from another developer or haven’t looked at the code in a few months.  Of course, XMLSpy has long included an XSLT debugger and XQuery debugger for setting break points and stepping through transformations to identify problems.

For a more interactive debugging process, XMLSpy also includes XSLT/XQuery back-mapping.

With back-mapping enabled, you can simply click on or hover over the portion of your output document you want to zero in on, and XMLSpy will immediately highlight the source XML and XSLT or XQuery instruction that is responsible. Let’s see how it works.
