Missing ELResolver on MyFaces 1.2 for ManagedBean Accesssing
Hi experts,
i try to access an RequestBean from a SessionBean like this:
final DebuggerBean db = (DebuggerBean) FacesContext.getCurrentInstance().getApplication().getELResolver().resolveVariable(facesContext, "neededBean");
This way is described here [1].
But i got an error that the needed classfile for ELResolver wasn't found on my classpath. The project is maven configured and these are my dependencies:
<dependencies>
<dependency>
<groupId>javax.faces</groupId>
<artifactId>jsf-api</artifactId>
<version>1.2</version>
</dependency>
<dependency>
<groupId>org.apache.myfaces.core</groupId>
<artifactId>myfaces-api</artifactId>
<version>1.2.8</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.apache.myfaces.core</groupId>
<artifactId>myfaces-impl</artifactId>
<version>1.2.8</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.apache.myfaces.tomahawk</groupId>
<artifactId>tomahawk12</artifactId>
<version>1.1.9</version>
</dependency>
<dependency>
<groupId>com.sun.facelets</groupId>
<artifactId>jsf-facelets</artifactId>
<version>1.1.14</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.4</version>
</dependency>
</dependencies>
How can solve the missing ELResolver class?
If i add the el-api and el-impl to the projects pom, the webserver won't start.
<!-- <dependency>-->

Hi
Try use provider scope to load EL api dependency:
<dependency>
<groupId>javax.el</groupId>
<artifactId>el-api</artifactId>
<version>1.0</version>
<scope>provided</scope>
</dependency>

Leonardo
