<%@ taglib uri="/WEB-INF/lib/struts-html.tld" prefix="html" %>

<html>

<head>
<title>MY FIRST JAVA STRUTS APPLICATION</title>
</head>

<body>

	<h1 align="center">MY FIRST JAVA STRUTS APPLICATION</h1>
	<html:link page="/TestRun.jsp">Test Run Application</html:link>
	
</body>

</html>

Any help would be highly appreciated...

Read the error message. It tells you exactly where the error is:

org.apache.jasper.JasperException: Exception in JSP: /index.jsp:15

File: index.jsp, line: 15

Also:

java.lang.NullPointerException
org.apache.struts.taglib.TagUtils.pageURL(TagUtils.java:1056)
org.apache.struts.taglib.TagUtils.computeURLWithCharEncoding(TagUtils.java:448)
org.apache.struts.taglib.TagUtils.computeURLWithCharEncoding(TagUtils.java:311)
org.apache.struts.taglib.html.LinkTag.calculateURL(LinkTag.java:463)
org.apache.struts.taglib.html.LinkTag.doStartTag(LinkTag.java:341)
org.apache.jsp.index_jsp._jspx_meth_html_005flink_005f0(index_jsp.java:95)
org.apache.jsp.index_jsp._jspService(index_jsp.java:67)

At that line you probably try to use something which is null

I have checked the line over and over again and I don't find anything wrong with it...

12: <body>
13: 
14: 	<h1 align="center">MY FIRST JAVA STRUTS APPLICATION</h1>
15: 	<html:link page="/TestRun.jsp">Customer Form</html:link>
16: 	
17: </body>

As you can see.. I am using the <html:link> tag to hyperlink 'Customer Form' to the TestRun.jsp that i have in the same folder... I fail to understand where there is something null in this statement :/
