Having JSF spit out an HTML Search field. Doable?

I'm not a Java developer, but work with a team that is using JSF 1.2
We'd like to start using HTML 5 tags and attributes. It does not appear that JSF 1.2 supports those by default.
Is there anyway to have a JSF text tag:
<x:inputText>
spit out an html 5 search tag:
<input type="search" placeholder="blahblah" />
Right now, I'm having to let it output a regular text field and then I place inline JS after it to trigger a function that converts it client side:
<input type="text">
<script> funciton here that changes type to 'search' and adds placeholder attribute</script>
It works, but is a bit hacky. Is there a legitimate way to get server-side JSF to output proper HTML 5 tags?

Create a custom component. This allows you fine grained control over rendered HTML.
Or upgrade to JSF 2.0, then you can create a composite component which is a lot easier.

Spring MVC: Relative URL problems

I have a controller bound the URL: "/ruleManagement".
Inside my JSP, I have a form that forwards (on submit) to "ruleManagement/save" url. When there are errors with the input fields, I want it to return back the original form View. This is where the problem starts...
Problem 1) Now that the URL is "/ruleManagement/save", my form submit now points to "/ruleManagement/ruleManagement/save".
Problem 2) I tried using spring:url tag to generate the absolute paths for me, which usually works great. But when I put a spring:url tag inside of a tag, the spring:url tag does not get parsed correctly.
<form:form action="<spring:url value='/ruleManagement/save' ...>" method="post">
When I analyze the DOM after the page loads, my form tag looks something like:
<form action='<spring:url value="/ruleManagement/save" />' ... >
If I don't use the spring:url tag, and instead use just "/ruleManagement/save", the url generated excludes my application name in the url, which is also wrong.
How do I generate a consistent URL pattern across all Views regardless of path? If the answer is "using spring:url", how do I get that content inside a form:form tag?

Custom tags in JSP can't be used in attributes of other custom tags, so you need to store intermediate result in a request attribute (using var to redirect output of the tag to the request attribute is a common idiom supported by many tags):
<spring:url var = "action" value='/ruleManagement/save' ... />
<form:form action="${action}" method="post">

I too would love to be able to generate a consistent URL path across all Views! Is this possible with <spring:url .../>.
To answer your second question & tacking on to axtavt's answer, embed the <spring:url ... /> into the form action after adding the property htmlEscape="true"
Example: <form:form action="<spring:url value="/ruleManagement/save" htmlEscape="true" .../>" method="post">

JSF runtime pagename passing

I have an include page which is a navigation menu. When i click on those menu i want to refresh the content area of layout with a certain page. How can i pass the page name into a JSF page using include tag
I dont want to switch to facelets and also i tried using $ and calling the backing bean method. It works but no css or richfaces components renders properly.
Thanks
Raj

I am not sure about the RichFaces part, but you can just use EL in <jsp:include> as well.
<jsp:include page="/WEB-INF/#{bean.pagename}.jsp" />
If bean.getPagename() returns for example home, then this will include /WEB-INF/home.jsp. You also need to ensure that the JSF/HTML contents of home.jsp is wrapped by a <f:subview> with an unique ID.
As to the CSS trouble, just ensure that the generated HTML validates and that the CSS imports in the <link> tags are all valid.

Write Multiple Full HTML 'Files' to Single Output Stream?

I'm writing a testing utility- I want to show multiple finished HTML "pages" in a single browser window.
Is this possible? I'm using Java Servlets.
For example, normally the user goes to a utility screen, fills in a bunch of fields and POSTS this to my servlet, which builds up a full HTML stream based on their input and writes it to HttpServletResponse.getWriter(). When the user views source, they get a <html> ... </html>.
What I want to do is allow users to request multiple "screens" and get the results in a single web page where you'd scroll down to see the 2nd, 3rd, etc. screens, maybe there is some kind of divider in between. I thought of frames or iframes, but didn't have luck. I have seen where I can write my big html stream to a javascript variable, then use document.write to dump it into the iframe. But that seems pretty awkward, and I'd have to be really careful about escaping quotes and stuff.

You will have to use iframes or frames to do this. A single web page can only contain one set of html tags and thus one html page.
Another idea would be to render the page by your script and then capture a picture of it and then have a page containing images. You will of course loose all interaction with the page.

I'm not sure what you're trying with your frames, but I imagine frames should work OK for what you've described.
Instead of trying to post to more than one URL from your form, you just post to a servlet that returns a page with the frameset, and each frame has a source that points to one of the URLs you want to test. For example:
<form action="testServlet" method="post">
<input type="text" name="someValue" />
</form>
The testServlet then returns a page with this content:
<frameset rows="33%,33%,33%">
<frame src="testUrl1?someValue=value">
<frame src="testUrl2?someValue=value">
<frame src="testUrl3?someValue=value">
</frameset>
The only problem with this is that you're doing a GET instead of a POST, but that's easy to get around. All you would need do is to implement the doGet method within your servlets and just call doPost from within doGet.

Just leave out the <html>/</html> tags for each page and wrap the whole thing inside a single large ....
Like this maybe:
<html>
[page1Content]
<hr />
[page2Content]
<hr />
[page3Content]
<hr />
</html>

Jasper report generating bad HTML

If I view the HTML generated by one of my Jasper reports in IE7 I see the following:
<BR /><BR />
<A name="JR_PAGE_ANCHOR_0_1">
<TABLE style="WIDTH: 1000px" cellSpacing="0" cellPadding="0" bgColor="#ffffff" border="0">
<-- table body omitted -->
</TABLE>
The two BR tags are added via the JRHtmlExporterParameter.HTML_HEADER parameter. After these tags and before the beginning of the report table that there's an unclosed anchor tag that is generated by Jasper reports. The fact that this tag is not correctly closed is messing up the formatting of my report because IE is hyperlinking the entire report TABLE. I'm not using this anchor tag, so if I could prevent Jasper from generating it, that would solve my problem.
Incidentally, this problem only occurs in IE, in Firefox everything works fine because the anchor tag is properly closed.
Thanks in advance,
Don

I took Phil's advice and dove into the Jasper source code. I've fixed the problem and submitted it to the project. Details of the cause and resolution are available here.

That's odd code, the <br /> tags are XHTML-style, while the unclosed a tags are good old HTML, like the upper case tag names. If you serve such page with plain HTML header/content-type, perhaps IE will be happy.
When you write that Firefox closes the tag, I suppose you mean it correctly doesn't extend the hyperlink span over block tags. Note that FF's view source can display closing tags that are not there when you save the page to disk!
Frankly, I don't know if you can get rid of these anchors with some config. If nobody comes with a real solution, maybe you can download Jasper's source code and search JR_PAGE_ANCHOR in it, looking if the code generating it is conditionally driven.
Or, if you can, you can apply post-processing of the generated code.

In excel export A1 cell transfor to JR_PAGE_ANCHOR_0_1.Some of tips are setting IS_ONE_PAGE_PER_SHEET property doing true, IS_DETECT_CELL_TYPE doing true but these are not working for me.
To avoid from this situation , configure your xlsx report configuration is worked for me (set ignore anchor is key point);
private final SimpleXlsxReportConfiguration xlsxReportConfiguration;
JRAbstractExporter exporter;
this.xlsxReportConfiguration = new SimpleXlsxReportConfiguration();
...
xlsxReportConfiguration.setIgnoreAnchors(true);
...
exporter = new JRXlsxExporter();
exporter.setConfiguration(xlsxReportConfiguration);
