77. Save the file as we did earlier, and close WordPad. 78. As we did earlier in the lab, move the main.html file to the EWEB using FTP. 79. Use the EWEB’s IP address to navigate to our homepage using Internet Explorer. You may need to press the browser’s refresh button to see the changes. Data Collection through XML One of the great benefits of the EWEB module is that it Queries and stores data in XML, a widely supported, platform independent file format. In this section, you will see some examples of how we can extract data from our XML data views. We will also see an example of how we can use email in our web pages. LAB 1: 1756-EWEB Module Page 16
80. Close ALL instances of Internet Explorer. You must close ALL instances of Internet Explorer in order to see the effects of the following steps! 81. Open a new Internet Explorer to get FTP access to the module as we did earlier in the lab. 82. Copy the UDWeb.html, UDXSL.html, UDEmail.html, and lab.xsl files from the AU2004\EWEB\XML folder to the EWEB. 83. Disable FTP. Administrative Settings � Device Configuration � Device Services � FTP disable checkbox. 84. Click Apply Changes. 85. Let’s look at the web page we downloaded in Internet Explorer: Type “10.88.89.2xx/user/web/UDXSL.html” using the IP address for your EWEB module. LAB 1: 1756-EWEB Module This popup appears because the web page we are loading does not have access to administrative data. You should get the error above. By default, the Data View XML files are accessible only by an administrator. There are three ways to solve this problem: Either lower the access restriction on the Data View, increase the access restriction on the html file, or do both. Eliminating all restrictions to the Data View will allow our page to load correctly, but anyone who can access the IP address of the EWEB module would have access to read, and perhaps write to the Data View. If, instead, we were to increase the access restriction on the HTML file to that of administrator, the user would be prompted to log in whenever they try to access the HTML file. This protects our Data View, but it limits the number of users who can use your page. However, we are going to reduce the access restriction on the Data View to write access and increase the access restriction on the HTML file to the same level. This protects our Data View while giving access to those who need it. 86. Go back to the EWEB Home page (10.88.89.2xx). 87. Navigate to Administrative Settings � User Management � Edit Access Limits Page 17
