Hello,

I’m using MyEclipse 7 (complete edition, not the Blue on) and the wizard to create a JSF web project with facelets support. After deploying it in Tomcat 6.0.18 the generated JSP file works correctly, but when I try to create a xhtml page like the examples at the facelets homepage https://facelets.dev.java.net/nonav/docs/dev/docbook.html#gettingstarted-view the page will not be rendered in the browser. When I look at the html source in the browser I always see the xhtml source code with all the tags (h:inputText …) in it. So no html code will be generated.
The web.xml and faces-config.xml look fine to me.

web.xml

  <context-param>
    <param-name>javax.faces.DEFAULT_SUFFIX</param-name>
    <param-value>.xhtml</param-value>
  </context-param>
  <servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>0</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.faces</url-pattern>
  </servlet-mapping>

faces-config.xml

    <application>
        <view-handler>com.sun.facelets.FaceletViewHandler</view-handler>
    </application></faces-config>

Also there’s no error at the MyEclipse console. So what I’m doing wrong ?

Lothar,
Did you go through the MyEclipse Facelet tutorial. Were you able to run though it without issues?
http://www.myeclipseide.com/documentation/quickstarts/facelets/

I followed the full tutorial of MyBlogFacelets but I used JBoss which shows error in running because of conflicting jars from the program and JBoss.

anyway how to run the example on jboss? The errror is

Hi all

I am now uisng MyEclipse for spring version 8.6 and I followed the tutorial in myeclipse help that runs on Derby server.

I try to run on JBoss and MySql but once I type the url http://localhost:8080/MyBlogFacelets/ and the click on a link I get the pop message of to save or open the file !!

so in a simpler question how to develop a helloworld facelet to run on Jboss 4 ?

Is there any program or tutorial ?

I do need to get the links of extension .faces to work with out getting the save or open question.

very many thanks to all who read or reply

Amir

amir55,

Can you try an example for me ?

Here are the steps :

1. Open the MyEclipse IDE.
2. From the menu open MyEclipse > Examples On-Demand.
3. There is a project ‘ SimpleFaceletsExample ‘. Click on ‘Install Project’ to install it to the workspace.
4. Try running this example on JBoss 4.

Let us know how this works for you.

[amir55]

hi dear repliers

I did install the example SimpleFaceletsExample from on demand and it deploys fine and screen is shown but when clicking on Click here I got this error on JBoss 4.2

java.lang.LinkageError: loader constraint violation: when resolving method “javax.faces.context.FacesContext.getELContext()Ljavax/el/ELContext;” the class loader (instance of org/jboss/web/tomcat/service/WebAppClassLoader) of the current class, com/sun/facelets/el/ELAdaptor, and the class loader (instance of org/jboss/mx/loading/UnifiedClassLoader3) for resolved class, javax/faces/context/FacesContext, have different Class objects for the type javax/el/ELContext used in the signature

so which jar to remove or add

many thanks

Amir

hi all dear love staff and colleagues

I am surprised why no one can answer a simple question of how to configure the example on demand MyBlogFacelets on JBoss.

I have been calling for a support for ages.

take care with best of thanks in anitcipation

Amir

[support-joy]

Amir,

My apologies for the late reply. Could you run the SimpleFaceletsExample on MyEclipse Tomcat? I have verified it works fine on MyEclipse Tomcat. I believe you are running on JBoss. I have escalated this to our dev team members. For the time being please use Tomcat to run the EOD.

Best.

[support-tony]

Amir,

Unfortunately, the SimpleFaceletsExample does not execute on JBoss due to a conflict with the el-api.jar file. JBoss already has this jar file in its set of server jars. Since it is deployed with the project (in the WEB-INF\lib folder), it ends up being loaded by two class loaders, which causes the problem.

I have raised a bug report for this.

There are a couple of workarounds. One is to remove the el-api.jar file from the deployed app (from WEB-INF\lib). The other is to remove the Facelets 1.1 libraries from the build path of the project and, instead, add two variables that point to the two jar files from the facelets library that are needed. To do this, configure the java build path for the project, click on the Libraries tab then click the Add Variable button, select MYECLIPSE_FACELETS_DATA_HOME then click the Extend button, then go to the facelets\lib folder and select both the el-ri.jar and the jsf-facelets.jar files (use the Ctrl key for multiple selections), then click the OK button. Don’t forget to remove the Facelets 1.1. libraries, if you haven’t already done so. Finish by clicking OK on the build path window. Remove the deployment then deploy again.

An alternative to using the variables is to create a user library, containing the two jar files, and use that instead.

[amir55]

so many thanks Tony

I have run the exmaple simply by adding jsf-faclelets.jar to library and it is ready to send to you if you like.

again so many thanks

Amir

[support-tony]

Amir,

I’m glad that solved the problem for you. Don’t worry about sending us your project as we can reproduce the problem here already.
