Introduction
So, this is another article where the main focus is to solve a specific error message occur upon executing a Java web application. Basically, the error message appear is not a regular error appear. Moreover, the error appear in two places. The first one, it appear in the page itself. The following is the actual image presenting the error message :
Furthermore, the second one appear in the output Tab. Actually, it is an error appear as part of the log exist in the output Tab of the NetBeans IDE. In this case, the Java web application is running using the help of a NetBeans IDE. So, the following is the error message exist in the NetBeans IDE as follows :

In order to make it simple, the following is the actual main error which exist above :
11:31:23,180 FATAL [javax.enterprise.resource.webcontainer.jsf.context] (default task-1) JSF1073: javax.faces.view.facelets.FaceletException caught during processing of RESTORE_VIEW 1 : UIComponent-ClientId=, Message=Error Parsing /db-connection-test.xhtml: Error Traced[line: 12] Attribute name "Connection" associated with an element type "titleDatabase" must be followed by the ' = ' character. 11:31:23,180 FATAL [javax.enterprise.resource.webcontainer.jsf.context] (default task-1) Error Parsing /db-connection-test.xhtml: Error Traced[line: 12] Attribute name "Connection" associated with an element type "titleDatabase" must be followed by the ' = ' character.: javax.faces.view.facelets.FaceletException: Error Parsing /db-connection-test.xhtml: Error Traced[line: 12] Attribute name "Connection" associated with an element type "titleDatabase" must be followed by the ' = ' character.
How to Solve Error Message appear in Java web application
Actually, the error message occur or appear in one of the Java web application’s page or exist in the output Tab it is because one of simple mistake. So, after checking the content of the file with the name of ‘db-connection-test.xhtml’, there is a slight miss-typed script in it. That script which is slightly miss-typed in the ‘db-connection-test.xhtml’ exist as follows :
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE html PUBLIC "-//W3C/DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets">
<h:head>
<titleDatabase Connection</title>
</h:head>
<body>
<h:form>
<p:outputPanel>
<p:outputLabel id="connectionStatus" value="#{dbConnectionTestView.status}"></p:outputLabel>
</p:outputPanel>
<p:commandButton type="submit" value="Alert" onclick="alert('Prime')" actionListener="#{dbConnectionTestView.submit()}" update="@form"/>
</h:form>
</body>
</html>
In detail, the following is the specific line which is causing the error :
<titleDatabase Connection</title>
As in the script exist in the line above, the script just has the opening format tag with the wrong one. The original purpose is to have the title tag opening and also closing. Inside that opening and closing title tag, there is a value string of ‘Database Connection’. So, in order to solve the problem, just revise the line as follows :
<title>Database Connection</title>
Last but not least, the overall script will be as follows :
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE html PUBLIC "-//W3C/DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets">
<h:head>
<title>Database Connection</title>
</h:head>
<body>
<h:form>
<p:outputPanel>
<p:outputLabel id="connectionStatus" value="#{dbConnectionTestView.status}"></p:outputLabel>
</p:outputPanel>
<p:commandButton type="submit" value="Alert" onclick="alert('Prime')" actionListener="#{dbConnectionTestView.submit()}" update="@form"/>
</h:form>
</body>
</html>
Finally, execute the page once more and the following display of the page will appear :
