Is there any way to reuse jsp -custom tags inside a html file?
My custom tag is already defined in a tld file and I am using that custom tag in a jsp file.
I want to reuse that custom tag in a html file.
How do I do this?
Below is the sample example of using my custom tag(btc:content) in a jsp file.
<div class="sfl-section-body">
<btc:content name="HOL-CF-307" />
I want to use (my custom tag) in an html file.

I am building an XPages application based on a custom theme I bought.
I want to use include pages to display custom 'widgets' in the header
Unfortunatelly, the included pages are rendered in a tag, which is incompatible with the css stylesheet from the theme.
Here's the code including the pages (the idea is to make this configurable in the future)
<xp:panel styleClass="navbar-account">
<ul class="account-area">
<xp:include pageName="/nav_VisitIn.xsp"></xp:include>
<xp:include pageName="/nav_MyVisit.xsp"></xp:include>
<xp:include pageName="/nav_Profile.xsp"></xp:include>
</ul>
</xp:panel>
The rendered html looks something like this
The css for the list item tags (and all elements below) are similar to
.navbar-account .account-area > li {...}
I want to avoid having to modify all related styles from the theme.
Is there a way to make sure the include page is rendered without the div tag or can I remove the generated div tag (but not its content) from the DOM?
Try adding disableOutputTag="true" in your <xp:include> tags.
I'm performing a F:AJAX call where I receive a byte Stream output whose content type is application PDF. I want this bytestream to be loaded in a JSF equivalent tag which should make me specify the content type as "Application/PDF" during tag declaration. Also, f:View fails saying content type not supported. Any JSF specific tags to cater this. Thanks.
Use iframe tag. This line shows how to use it:
<iframe src="foo.pdf" width="600" height="400" scrolling="no"></iframe>
If you also want to hide the (default) border, add frameBorder="0".
There is also pdf.js library that allows to browse pdf in browser. https://blog.oio.de/2014/04/11/integrating-pdf-js-pdf-viewer-web-application/
The answer is no there isn't such a tag.
To be honest there's no need to change it, since using HTML for this is fine and really the simplest way. You can use IFRAME (like Jay Smith shows you) or OBJECT.
The same way is presented on PrimeFaces's showcase:
<h3>PDF</h3>
<object type="application/pdf"
data="/showcase/resources/demo/media/guide.pdf?pfdrid_c=true"
height="300px" width="100%" internalinstanceid="3">
Your browser can't display pdf,
click
to download pdf instead.
</object>
I've found that when changing an included file, if I use the include action tag, then the change is reflected in the including jsp. But if I use the include directive, then the the change is not reflected in the including jsp.
However, I've found that the change does get reflected in the including jsp whether we use include action tag or include directive.
Please show me the difference using a program.
The contents of the directives form part of the main JSP during the translation phase, ie., when the JSP is compiled in to an equivalent servlet. So the contents from the jsp included using a directive componnet are merged in to the parent jsp at the translation time which happens only once. This include directive was mainly meant to be used for addressing the headers and footers which are mostly static that doesn't get changed often.
The include action tag on the other hand is for including dynamic contents ie., you can choose to send a parameter to the tag which that tag may process and display. this is unlike the headers and footers showing the same content again and again.
Main.jsp
<jsp:include page="included.jsp">
<jsp:param name="message" value="World" />
</jsp:include>
Included.jsp
<html>
<head>
</head>
<body>
<h2>Hello <%=request.getParameter("message") %></h2>
</body>
</html>
Also what server are you using. Since Tomcat7, things have changed and the main jsp will also compile if the included jsp(by any mechanism) is changed.
this link has more details.
I read number of posts about the same issue and the solution from the "tomcat server" side is to add element inside element and what i did like this :
<Host>
<Context docBase="path_to_image" path="/images" />
.....
My issue now is that if i tried to display the image by html image tag like that :
<img src="/images/dist/image_name.ext"/>
the image rendered without any problem , but i have aproblem when use the jsf tag like :
<h:graphicImage value="/images/dist/image_name.ext" />
this tag's output is : [http://localhost:8080/context_name/faces/images/dist/image_name.ext]
so i think if i can point to [http://localhost:8080/images/dist/image_name.ext] from the jsf component it will solve the issue but how can i make this ?
Any idea ?
I see this article http://balusc.blogspot.com/2007/04/imageservlet.html
but it will be betterif i can solve that issue by the server.xml as i mentioned before .
The <h:graphicImage> will indeed implicitly prepend the webapp context path to image's URL. Just don't use it and stick to plain HTML <img> element. Whatever reason you've in mind which would require it to be a <h:graphicImage> component needs to be reconsidered or solved differently so that you can keep using plain HTML <img>. element.
I have a Jsp that dynamically needs to get included in entire project as user opens any jsp. i.e. As a user opens a jsp my jsp should automatically gets included.
I have written this in web.xml in Tomcat
<jsp-property-group>
<url-pattern>/webapps/ROOT/html/*.jsp</url-pattern>
<url-pattern>*.jspf</url-pattern>
<el-ignored>false</el-ignored>
<scripting-invalid>false</scripting-invalid>
<is-xml>false</is-xml>
<include-prelude>/WEB-INF/jsp/tracker.jsp</include-prelude>
<!-- <include-coda>/template/coda.jspf</include-coda> -->
</jsp-property-group>
I had kept my jsp in tomcat under WEB-INF/jsp/ and i want to include it into every porject as it contains a code that tracks log for user.
Or any other way to make this happen.
Thanks.
There is one more way to include your JSP for the whole portal and i.e. the dockbar.
You can create a hook and include your jsp in the /html/portlet/dockbar/view.jsp using either <jsp:include /> or <liferay-util:include /> or simple <%# include file="" /> (this would be static).
<jsp:include page="/jsp/yourJSPPageToBeIncluded.jsp" />
OR
<liferay-util:include page="/jsp/yourJSPPageToBeIncluded.jsp" />
OR
<%# include file="/jsp/yourJSPPageToBeIncluded.jsp" />
Note: the path may differ depending on where you will be putting the JSP.
Why I am choosing dockbar is because it is present on all the portal-pages of liferay. This won't work if you are opening a pop-up like configuration pop-up or look-and-feel pop-up or other custom dialog pop-ups since dockbar is not present in the pop-up. For using in pop-ups you would have to override portal_pop_up.vm in your custom-theme and write the code as suggested by #VikasV
$theme.include($themeServletContext, "/jsp/yourJSPPageToBeIncluded.jsp")
There are two ways for this.
Simple way is to include your JSP in the Theme. When your Theme is applied to your project, and when Theme is rendered, any pages in your project will render this included JSP.
Code sample below. This has to be placed in vm file(navigation.vm).
$theme.include($themeServletContext, "/jsp/yourJSPPageToBeIncluded.jsp")
Here, JSP folder is placed directly inside Theme war.
Other way (tedious one), is to include this JSP in each and every JSP page that you want this to be included.
Use <jsp:include> element for this.
