I am trying to use a custom tag in a jsp page but I get compilation errors so far.
Here is the custom jsp tag code along with the jsp page that is trying to use it.

/Users/skiabox/NetBeansProjects/simplewebapp2/nbproject/build-impl.xml:612:
Java returned: 1 BUILD FAILED (total time: 2 seconds)
As you can see the first error occurs when the code is trying to access addressBean.state
Any ideas on how to fix that or what am I doing wrong?
Thank you.
I know it is very late (over 3 years) to answer this question. I have also had this problem. Apparently the solution is "Clean and Build Project" or press SHIFT+F11 and run again the project.

I need to convert a JSP file to an equivalent JSF file. The JSP is as follows:
Step 1: Class Import:
<%# page import="org.keycloak.constants.ServiceUrlConstants" %>
<%# page import="org.keycloak.common.util.KeycloakUriBuilder" %>
<%# page session="false" %>
<html>
Step 2: Define a variable:
<%
String logoutUri = KeycloakUriBuilder.fromUri("/auth").path(ServiceUrlConstants.TOKEN_SERVICE_LOGOUT_PATH).queryParam("redirect_uri", "/customer-portal").build("demo").toString(); %>
Step 3: Then refers to this variable:
logout
The imported library is an external library into the project. In JSF, I know how to do Step 3. But I don't know how to import the classes in Step 1 and how to define a variable as shown in Step 2 in JSF.
Is there an equivalent way of performing Step 1-3 in JSF? Thank you.
You can't call Methods directly in JSF or create variables, therefore you don't need imports.
The only way is to use EL-Expressions.
Since calling static Methods is not possible with EL, you'll have to create yourself a Bean, that makes the call of KeycloakUriBuilder.fromUri...
With a Named Bean you call its Methods:
Example:
import java.io.Serializable;
import javax.enterprise.context.RequestScoped;
import javax.inject.Named;
//This Bean is available by default under the Name 'myBean', you can change it in the #Named Annotation if desired
#Named
#RequestScoped
public class MyBean implements Serializable {
public String myMethod(String inupt){
return "Hello " + input;
}
}
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
xmlns:f="http://java.sun.com/jsf/core" >
<head></head>
<body>
<h:outputText value ="#{myBean.myMethod('world')}"/>
</body>
</html>
Will give you this HTML:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head></head>
<body>Hello world
</body>
</html>
The preferred way to show Something on the page is to use getters and setters, if you have a field with getter and Setter
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
You can just use
#{myBean.name}
JSF will call the getter if it needs the value (for output) or call the Setter if there is a value to set (from input-fields)
The <%# page session="false" %> is also neither needed nor possible.
In JSF the Bean has a Scope, this example with RequestScoped should be a good match for <%# page session="false" %> - a Request Scoped Bean lives only for one Request, after that the Bean is disposed. There are many other scopes, e.g. #SessionScoped (from javax.enterprise.context) for a Bean that lives as long as the Session is active.
As mentioned by another User, those Scopes exists in the CDI-Variant (Package javax.enterprise.context) and a JSF-variant (package javax.faces.bean). You should use the CDI-Variant, since the JSF-Variant might be deprecated soon (see here).
Explanation of the Scopes see here.
I use Spring Boot, JSF, PrimeFaces.
Right now, I can't update my application to new JSF 2.2.12.
Everything works properly for example with JSF 2.2.8-06 and PrimeFaces 5.2 but starting from JSF 2.2.8-07 and up to 2.2.12 version I can't reach my ManagedBean from XHTML page.
What was changed from JSF 2.2.8-07+ version and how to fix it ?
My bean:
#ManagedBean
#ViewScoped
public class HelloBean implements Serializable {
private static final long serialVersionUID = 8569928214435846079L;
public String getHello() {
return "Hello from PrimeFaces and Spring Boot!";
}
}

WebInitializer:
#Configuration
public class WebInitializer extends SpringBootServletInitializer implements ServletContextAware {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
#Bean
public DispatcherServlet dispatcherServlet() {
DispatcherServlet dispatcherServlet = new DispatcherServlet();
dispatcherServlet.setThrowExceptionIfNoHandlerFound(true);
return dispatcherServlet;
}
#Bean
public ServletRegistrationBean servletRegistrationBean() {
FacesServlet servlet = new FacesServlet();
ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(servlet, "*.xhtml");
servletRegistrationBean.setLoadOnStartup(1);
return servletRegistrationBean;
}
#Bean
public ServletListenerRegistrationBean<ConfigureListener> jsfConfigureListener() {
return new ServletListenerRegistrationBean<ConfigureListener>(new ConfigureListener());
}
#Override
public void setServletContext(ServletContext servletContext) {
servletContext.setInitParameter("com.sun.faces.forceLoadConfiguration", Boolean.TRUE.toString());
}
}
With JSF 2.2.8-06 everything works properly except following errors in the console:

UPDATED
I got it working:
I have added resources/META-INF/faces-config.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<faces-config xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd"
version="2.2">
<application>
<el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
</application>
<lifecycle>
<phase-listener>org.springframework.web.jsf.DelegatingPhaseListenerMulticaster</phase-listener>
</lifecycle>
</faces-config>
and also changed annotations in my HelloBean, not it looks like:
#Named
#ViewScoped
public class HelloBean implements Serializable {
private static final long serialVersionUID = 8569928214435846079L;
public String getHello() {
return "Hello from PrimeFaces and Spring Boot!";
}
}
Is it a proper way to go ? Is it a good idea to use #Named instead of #ManagedBean ?
I am new to Liferay , i am unable to navigate through Pages using renderURL , please tell me where i am doing a mistake
I am struck here , i am not able to navigate to the Second Page during on click of an hyper link as shown below
This is my First Page , where i am showing the First Page ( view.jsp ) , But from view.jsp , i am unable to show view2.jsp
public class TestPortlet extends GenericPortlet {
public void doView(RenderRequest renderRequest,
RenderResponse renderResponse) throws IOException, PortletException {
renderResponse.setContentType("text/html");
PortletRequestDispatcher rd = getPortletConfig().getPortletContext()
.getRequestDispatcher("/html/test/view.jsp");
if (rd != null) {
rd.include(renderRequest, renderResponse);
}
}
}
This is my view.jsp
<%# taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet" %>
<portlet:defineObjects />
This is the <b>Sai Test Portlet</b> portlet in View mode.
<portlet:renderURL var="clickRenderURL">
<portlet:param name="jspPage" value="/html/test/view2.jsp" />
</portlet:renderURL>
Click here
This is my view2.jsp
<%# taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet" %>
<portlet:defineObjects />
This is the <b>View 2 </b> portlet in View mode.
There are no errros in console mode , and i am uisng Liferay 6.1 version .
Can you check the same using
"liferay-portlet:renderURL" tag.
Instead of using "portlet:renderURL" tag.
Rest all looks fine to me.
I want to fill an selectOneMenu with fields from my DataBase
and then use the chosen value in another request SQL.
For know I have my selectOneMenu filled from my data but I dont Know how to retrieve the chosen value and show it into another page. The error is:

You forgot the <f:view> in Result.jsp. All JSF components has to go inside a <f:view>. Edit your Result.jsp so that it look like the following basic template:
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<%#taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%#taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<!DOCTYPE html>
<f:view>
<html lang="en">
<head>
<title>JSP page</title>
</head>
<body>
<h:outputText value="JSF components here." />
</body>
</html>
</f:view>
I am getting the "This attribute does not support request time values." while compiling my custom jsp tag implementation.
My TLD file

My JSP Tag Implementation has the following method
/**

*/
public int doStartTag() throws JspException {
try {
JspWriter out = pageContext.getOut();
out.println(getContent());
} catch (Exception ex) {

}

return SKIP_BODY;

String linkURL = ViewConstants.BASE_URL;
StringBuffer sbuffer = new StringBuffer();

return sbuffer.toString();
}
public int doEndTag() throws JspException {

}
my jsp has the following
<%# taglib uri="/WEB-INF/view.tld" prefix="cmd" %>
.....
<cmd:requireDisplay viewID="<%=vox.getViewID()%>" viewType="<%=vox.getViewType()%>"/>
But i am getting the following exception
[jspc] Error encountered while compiling 'jspURI'
view_details.jsp:136:22: The required attribute "viewID" is missing.
<cmd:requireDisplay viewID="<%=vox.getViewID()%>" viewType="<%=vox.getViewType()%>"/>

Am i missing anything? As in the tld, even i tried to give TagExtraInfo too. But no luck.
Any help is much appreciated.
I figured out the issue.
It is a typo :(
<rtexpvalue>true</rtexpvalue>
entry suppose to be
<rtexprvalue>true</rtexprvalue>
