Question

i need your help with this error in my proyect spring 3 and weblogic sever,

java.lang.NoSuchMethodError: javax.el.ELResolver.invoke(Ljavax/el/ELContext;Ljava/lang/Object;Ljava/lang/Object;[Ljava/lang/Class;[Ljava/lang/Object;)Ljava/lang/Object;
at com.sun.el.parser.AstValue.getValue(AstValue.java:111)
at com.sun.el.parser.AstValue.getValue(AstValue.java:163)
at com.sun.el.ValueExpressionImpl.getValue(ValueExpressionImpl.java:219)

i tried adding el-api-2.2 and el-impl-2.2 and nothing happens and modify my weblogic-application.xml

    <wls:application-param>
    <wls:param-name>webapp.encoding.default</wls:param-name>
    <wls:param-value>UTF-8</wls:param-value>
</wls:application-param>

<wls:prefer-application-packages>
    <wls:package-name>javax.el.*</wls:package-name>
    <wls:package-name>com.sun.el.*</wls:package-name>
            <wls:package-name>javax.faces.*</wls:package-name>

Answer 1

The error is because weblogic library contain jsf and el, for resolved this error, is necessary adding this segment in weblogic.xml and any description should be set in false

<container-descriptor>
    <prefer-application-packages>
        <package-name>javax.el.*</package-name>
        <package-name>com.sun.el.*</package-name>
        <package-name>javax.faces.*</package-name>
        <package-name>com.sun.faces.*</package-name>
        <package-name>org.springframework.*</package-name>
        <package-name>antlr.*</package-name>
    </prefer-application-packages>
</container-descriptor>  

Thanks for all
