My team is experiencing this issue as well. On both Windows and Linux.

SCooper4711 ,
Are you facing this issue on MyEclipse 6.0 ?

Can one of you guys post a sample page here so that I can test this at my end.

Problem is the error is random, you can open the page several times, it's fine, open again and you get then nullpointer error. Sometimes closing eclipse will make it go away, somtimes not. I reintalled the product to fix the issue last time.

Code:

<%@ page language="java" pageEncoding="ISO-8859-1"%> <%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %> <%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head>    <title>My JSF 'Main.jsp' starting page</title>        <meta http-equiv="pragma" content="no-cache">    <meta http-equiv="cache-control" content="no-cache">    <meta http-equiv="expires" content="0">       <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">    <meta http-equiv="description" content="This is my page">      <link href="../Styles.css" rel="stylesheet" media="screen"></link> </head>   <body>    <f:view>          <h:outputText value="Hello this is a test page." styleClass="ValidateError"/>          <br>          <h:outputText value="#{main.companyType}" /><br>          <h:outputText value="#{main.contactfirstname}" /><br>          <h:outputText value="#{main.contactlastname}" /><br>          <h:outputText value="#{main.addressline1}" /><br><div class="PropertyName">Hello there</div>          <h:dataTable id="SampleDatatable" border="1" var="idx" rows="10"                value="#{main.companyList}"              rowClasses="list-row-odd,list-row-even"              headerClass="table-header" >             <h:column id="column1">                <f:facet name="header">                   <h:outputText value="First Name" />                </f:facet>                 <h:outputText value="#{idx.contactfirstname}" />             </h:column>                         <h:column id="column2">                <f:facet name="header">                   <h:outputText value="Last Name" />                </f:facet>                 <h:outputText value="#{idx.contactlastname}" />                          </h:column>                         <h:column id="column3">                <f:facet name="header">                   <h:outputText value="Address" />                </f:facet>                 <h:outputText value="#{idx.addressline1}" />                         </h:column>                      </h:dataTable>       </f:view> </body> </html>

I'll will "make a note" and if you are able to find a situation where it happens all the time to let me know ASAP.

Hi,

i have the same problems.
- after install the editor works fine.
- after opening some files the exception ist thrown
- in my case there is no jsp file (in several projects) that can be opened, after the first occurrence of the exception

Arndt

Hi,

I have a similar problem. Every time I try to open a jsp page, which contains JSF tags, a null Pointer Exception is raised. The whole Project is configured as JSF-Project

I figured out, that this should be a problem with the MyEclipse visual editor and the use of any graphical elements, like <h:graphicalImage />, <img> or just a Stylsheet. If the path is a relative one like "img/myPicture.jpg", there is no problem and no exception is thrown. But if the path is a absolute one like "/img/myPicture.jpg", every time a nullpointer exception is thrown. It does not matter, if the path is inside a JSF component or a simple HTML-Tag.

Jochen

Hi Jochen,
People who have not been using the graphical elements have also reported this error. We are trying to figure out what causes this. In any case, Ill take a note of your findings.

Thanks.

Hi,

I and having numerous errors popup with 6.0 GA, the errors fall into two buckets, an unhandled loop exception in org.eclipse.ui and org.eclipse.jst.jsf.common.ui.internal.utils.WebrootUtil.getWebContentPath. Would be worth checking how the web content path is now resolved. I paste the exception below. Please post back if you need the full installation information.

Exception:

Can one of you guys send me a test project. Im going to file this bug for my Dev team.

Thanks for sending the project. I have filed a bug. Ill get back to you guys with an update ASAP.

We have exactly the same problem... and it's really annoying for our JSF team !
No news about ?
Thanks for your help !!

Guys,
For the folks having problems opening JSF pages and getting the getWebContentPath NullPointerException, do you have *images* in your page? We found a bug during testing internally where images are resolved incorrectly in the project because the wrong webRoot dir is used, and it was causing exceptions.
