I'm running Weblogic 10.3.6 and trying to build a new dynamic web application (in eclipse) that supports JSF 2.2.8 and EL 2.2 and JDK 1.7 U45, but unfortunately EL 2.2 is throwing an exception.

The weblogic.xml

<?xml version="1.0" encoding="UTF-8"?>

        </wls:prefer-application-packages>
    </wls:container-descriptor>        
</wls:weblogic-web-app>


The following exception is thrown trying to run a page with an parameterized method call in EL

Changing the weblogic.xml <container-descriptor> to

<wls:container-descriptor>
    <wls:prefer-web-inf-classes>true</wls:prefer-web-inf-classes>
</wls:container-descriptor>

yields the same exception above, untill I add the following to the web.xml

<context-param>
    <param-name>com.sun.faces.expressionFactory</param-name>
    <param-value>com.sun.el.ExpressionFactoryImpl</param-value>     
</context-param>

Then the exception thrown changes to

I don't understand how weblogic is behaving, the same steps worked with other develobers as in the second answer in this question

    Looks like a library confusion; there might be multiple distributions of JSF/EL available to the app server, causing the conflict. Use [JBoss's tattletale](http://tattletale.jboss.org/) to cleanup your classpath – kolossus Feb 03 '15 at 05:31

Here is my workaround for EL in the old weblogic:

<context-param> <param-name>com.sun.faces.expressionFactory</param-name> <param-value>org.jboss.el.ExpressionFactoryImpl</param-value> </context-param>

  • Enjoy parameterized method calls. No other configuration required (no library-refs, no prefer-application-packages, no prefer-web-inf-classes)

I ran into a similar error trying to deploy JSF 2.2 in WebLogic 12.1.3. The accepted answer didn't quite suffice, or at least it lead to other errors. The following did the trick:

web/pom.xml:

<dependency>
            <groupId>com.sun.faces</groupId>
            <artifactId>jsf-api</artifactId>
            <version>2.2.13</version>
        </dependency>
        <dependency>
            <groupId>com.sun.faces</groupId>
            <artifactId>jsf-impl</artifactId>
            <version>2.2.13</version>
        </dependency>
        <dependency>
            <groupId>javax.el</groupId>
            <artifactId>el-api</artifactId>
            <version>2.2</version>
        </dependency>
        <dependency>

        </dependency>
        <dependency>

I have found a bit of a work around on the Oracle forums, it encapsulates the WAR in an EAR and uses the EAR's weblogic-application.xml to basically enforce the same package references but apparently this time weblogic honors the preferences and it works fine.

Still don't know how to do that with only a WAR file.

Solution posted on the forums

For me the following worked:

Weblogic 10.3.5.0

I have a JavaEE application with both ejbs in EJB container and Facelets in Web container.

I added /META_INF/weblogic-application.xml : 

    <?xml version = '1.0' encoding = 'windows-1252'?>
<weblogic-application xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.oracle.com/weblogic/weblogic-application http://xmlns.oracle.com/weblogic/weblogic-application/1.1/weblogic-application.xsd"
xmlns="http://xmlns.oracle.com/weblogic/weblogic-application">
<prefer-application-packages>
<package-name>com.sun.el.*</package-name>
<package-name>javax.el.*</package-name>
</prefer-application-packages>
</weblogic-application>

Included el-api-2.2.jar and el-impl-2.2.jar to the WEB-INF/lib library.

it works, it does not work for me when using the weblogic.xml

Thank you "965902" whoever you are !
