Seems like we get a lot of these configuration errors in the bug
reports; the error
is admittedly a bit obscure.
This patch may reduce the confusion somewhat:
public TableTag(){
public int doStartTag() throws JspException {
try { // this class is new in commons-lang 2.0
Class.forName("org.apache.commons.lang.WordUtils");
} catch(ClassNotFoundException e){
try {
Class.forName("org.apache.commons.lang.enum.Enum");
throw new JspTagException("\n\nYou appear to have an
INCOMPATIBLE VERSION of the Commons Lang library. " +
"Displaytag requires version 2 of this library,
and you appear to have a prior version in your " +
"classpath. You must remove this prior version
and ensure that only version 2 is in your classpath. " +
"Be sure to delete all cached or temporary jar
files from your application server; Tomcat users " +
"should be sure to also check the
CATALINA_HOME/shared folder; you may need to restart the server. " +
"commons-lang-2.jar is available in the
displaytag distribution, or from the Jakarta website at " +
"http://jakarta.apache.org/commons \n\n.");
} catch (ClassNotFoundException ee ){
throw new JspTagException("You do not appear to have the
Commons Lang library, version 2. " +
"commons-lang-2.jar is available in the displaytag
distribution, or from the Jakarta website at " +
"http://jakarta.apache.org/commons . ");
}
}
// continue with the method.
}

> uses the tag <display:table>
>
> <display:table> works fine if I call the struts Action
> servet directly from browser
> Eg# http://someURL/mytest.do
>
> But if I call the same Action servlet from a form
> EG# <html:form action="/mytest.do"> the same JSP
> throws exception after org.display.tags.TagTable=
> doStartTag().
>
> The exception is:java.lang.Exception:
> org/apache/commons/lang/StringEscapeUtils

> Any suggestion ?? The Action servlet, The Data being
> forwarded in ArrayList and the JSP is the same. Only
> difference in how the Action servlet is being called.
