Looks like my last post was not sucessful,
Can someone please tell me this is not a bug in Tomcat 6, its too obvious
and to some extend unacceptable I must be doing something wrong.
Here is my problem, I have written my own custom component to display a div
tag.
the JSP is as follows:
<faces:view>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<title>My Custom Tags</title>
</head>
<body>
<html:form>
<h2>Cat In The Rain</h2>
<mine:mytag title="#{index.title}">Dancing in the rain.</mine:mytag>
</html:form>
</body>
</html>
</faces:view>
The tag class is given below:
This text #{index.title} is being interpreted as Literal text which is
obviously wrong, when deployed in glassfish the code works fine.
Output text in my tomcat console is
MyTag.setProperties(): Title is literal text....
MyTag.setProperties(): title value= #{index.title}
MyTag.setProperties(): Title Value expression is null
The Tag class.
public class MyTag extends UIComponentELTag{
private ValueExpression title;
public String getComponentType() {
return "test.MyOutput";
}
public String getRendererType() {
return "test.MyRenderer";
}
@Override()
protected void setProperties(UIComponent component) {
super.setProperties(component);
if (null!= title){
if (!title.isLiteralText()){
component.setValueExpression("component.title", title);
System.out.println("MyTag.setProperties(): Its not literal text.");
System.out.println("MyTag.setProperties (): title value
= "+ title.getValue(getELContext()));
}
else{
component.getAttributes().put("component.title",
title.getExpressionString());
System.out.println ("MyTag.setProperties(): Title is literal
text....");
System.out.println("MyTag.setProperties(): title value=
"+ title.getExpressionString());
}
}
System.out.println ("MyTag.setProperties(): Title Value expression is "+
component.getValueExpression("component.title"));
}
The component class.
public class MyOutput extends UICommand{
public MyOutput(){
setRendererType("test.MyRenderer");
}
@Override()
public String getFamily() {
return "test.MyOutput";
}
}

<description>
A ValueExpression that resolves to the UIComponent that
corresponds
to this tag. This binding allows the Java bean that contains the
UIComponent
to manipulate the UIComponent, its properties, and its children.
