Richfaces 4 datatable in not rendering

[kishi_kiran]

Hello everyOne,

I am in the process of migrating Richfaces 3.x to 4.x, using JSF 2.0

Here I have used rich:dataTable component inside h:form, but it is not getting dispalyed.

in browser view source it is not convering in to html format, its still showing rich:dataTable.

and we don't place any new rich.tld files in WEB-INF folder,

but previous 3.x version i had this rich.tld, richfaces.tld files in my WEB-INF folder.

can some one help me out on this, what could be the problem here to render the dataTable ?

Thanks

kiran.

hi,

I think you should start with some RF example project and check the defference, the jboss tool can generate one for you. I guess your probleme is in your web.xml.

[kishi_kiran]

Yes You are Right ,

I have removed this bit of configuration in WEB-INF as well as faces-config.xml file then i can able to see the datatable.

<context-param>

        <param-name>org.ajax4jsf.VIEW_HANDLERS</param-name>

        <param-value>com.sun.facelets.FaceletViewHandler</param-value>

    </context-param>

<view-handler>com.sun.facelets.FaceletViewHandler</view-handler>

is it the correct on what I did?

Thank you .

Hi,

yes, it's correct...these settings are not necessary anymore because facelets are default in JSF 2.

Thank You for your help,

Here after removing the 'FaceletViewHandler' in faces-config file I have got another errors like,

1. ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/logit4see].[Faces Servlet]] (http--127.0.0.1-8080-4) Servlet.service() for servlet Faces Servlet threw exception: java.lang.LinkageError: loader constraint violation: when resolving method "javax.faces.application.Application.createBehavior(Ljava/lang/String;)Ljavax/faces/component/behavior/Behavior;" the class loader (instance of org/jboss/modules/ModuleClassLoader) of the current class, org/richfaces/view/facelets/html/AjaxHandler, and the class loader (instance of org/jboss/modules/ModuleClassLoader) for resolved class, javax/faces/application/Application, have different Class objects for the type javax/faces/component/behavior/Behavior used in the signature.

2.One or more resources have the target of 'head', but no 'head' component has been defined within the view.

3. I have used c:if component in one of the page, its is also not working as expected.

what could be the problem here?

can some body help me on this.

[liuliu]

hi,

1. You really need start with a clean RF4 project to check the configuration. probablely you have a jar conflit.

2. you should always have a head in the final JSF page.

3. c:if  is still available. but it depends what you want, rendered is prefered.

[ppitonak]

1. As liuliu wrote, check that you don't include mojarra/myfaces jar in your war.

2. You need to have h:head tag on your page or in your template.

[kishi_kiran]

Thank you all,

yes Pavol,

2.after adding the h:head insetead of head in template.xhtml page all the styles are getting applied.

1.and i have have checked in libraries for majarra, i have already removed majarra_ext.tld from WEB-INF. still i am getting the linkage error,

one more thing i have html_basic.tld file in WEB-INF which is of version JSP1.2. is it causes any problem to that ? this one also i have removed still same linkage error.

and i am in the middle of migration so i cannot do it from scratch thats the problem i am facing.

[ppitonak]

How do you manage your dependencies? Do you use Maven? There is no reason to have tld files in WEB-INF directly inside your war.

[kishi_kiran]

Yes Pavol,

I am using Maven.

[ppitonak]

The best way for inluding RichFaces 4 to your Maven project is using BOM like this:

<project ...>
...
<properties>
<version.richfaces>4.3.5.Final</version.richfaces>
</properties>
<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.richfaces</groupId>
                <artifactId>richfaces-bom</artifactId>
                <version>${version.richfaces}</version>
                <scope>import</scope>
                <type>pom</type>
            </dependency>
</dependencies>
</dependecyManagement>
<dependencies>
        <!-- Dependencies for RichFaces -->
        <dependency>
            <groupId>org.richfaces.ui</groupId>
            <artifactId>richfaces-components-ui</artifactId>
        </dependency>
        <dependency>
            <groupId>org.richfaces.core</groupId>
            <artifactId>richfaces-core-impl</artifactId>
        </dependency>
</dependency>
...
</dependencies>
...
</project>

You can also check on of our examples richrates/pom.xml at 4.3.2.Final · ppitonak/richrates · GitHub

Yes I too have the same configuration in my main  pom

<properties>

<richfaces.version>4.2.1.Final</richfaces.version>

</properties>

<dependencies>

  <dependency>

    <groupId>org.richfaces</groupId>

       <artifactId>richfaces-bom</artifactId>

                <version>${richfaces.version}</version>

                <type>pom</type>

                <scope>import</scope>

    </dependency>

  </dependencies>

<dependencies>

<dependency>

    <groupId>org.richfaces.ui</groupId>

            <artifactId>richfaces-components-api</artifactId>

            <scope>compile</scope>

        </dependency>

        <dependency>

            <groupId>org.richfaces.ui</groupId>

            <artifactId>richfaces-components-ui</artifactId>

            <scope>runtime</scope>

        </dependency>

        <dependency>

            <groupId>org.richfaces.core</groupId>

            <artifactId>richfaces-core-impl</artifactId>

            <version>4.2.1.Final</version>

            <scope>runtime</scope>

        </dependency>

<dependencies>

I think it does not make any difference, is it any wrong here in my configuration ?

[ppitonak]

1. Which container do you deploy to?

2. What is in WEB-INF/lib inside your war?

[kishi_kiran]

Hi poval sorry for delayed reply,

I am using JBoss 7.1.1 Final.

here now the dataTable is working, like i have removed the all tlds from WEB-INF, removed view-handler in faces-config and maintain the h:head and h:body in template.xhtml page.

but when i am using a4:ajax (RF4.x) instead of a4j:support (RF3.x) again the same linkage error.

java.lang.LinkageError: loader constraint violation: when resolving method "javax.faces.application.Application.createBehavior(Ljava/lang/String;)Ljavax/faces/component/behavior/Behavior;" the class loader (instance of org/jboss/modules/ModuleClassLoader) of the current class, org/richfaces/view/facelets/html/AjaxHandler, and the class loader (instance of org/jboss/modules/ModuleClassLoader) for resolved class, javax/faces/application/Application, have different Class objects for the type javax/faces/component/behavior/Behavior used in the signature.

these are all the jar files which i have used in my ear/lib.

but inside UI war/WEB-INF i do not have any lib folder.

can you help me on this what could be the problem?

Thanks in Advance!

Kishi kiran.

[ppitonak]

Hi,

I think that it might be caused by jsf-api or jsf-impl in your ear/lib. First, try to remove these two jars. You also don't need jsf-facelets jar because Faceletes are default view declaration language in JSF 2.

I have few other suggestions for you:

• Upgrade you application to RichFaces 4.3.5.Final which contains several important bug fixes.
• Consider migrating from JBoss AS 7.1.1 to WildFly 8.0.0. JBoss AS is no longer developed and it was renamed to WildFly.
• There are many JEE jars which are provided to your application by application server, such as weld, jaxb, javax.inject, hibernate-entitymanager. You should depend on what applcation server provides you unless you have some special requirements.
• If you need EAR packaging of your application, have a look on one of WildFly's quickstarts quickstart/kitchensink-ear at master · wildfly/quickstart · GitHub
