Error by parsing an JSP Site

[Former Member]

Hello!

First - sorry for my english.

I have an webapp that perfectly work in tomcat and jetty but fails in WAS6.40 SP9. The important part of the jsp looks like this:

<%@ page import="de.cdiag.skills.web.resources.Constants" %>

[...]

<%@ taglib uri="/WEB-INF/displaytag-11.tld" prefix="display" %>

[...]

<%-- this ist the line 38 --%>

<display:table id="skills" class="smTable test" name="<%= Constants.SKILL_LIST_KEY %>">

[...]

</display:table>

if i start the application that throws following exception:

Hi Dimitri,

i got the same problem as described on :

Did you already found a solution how to deal with this displaytag-tld problem?

hope to hear from you. thx in advance,

lars

[detlev_beutner]

Hi Dimitri,

as Astrid said, it is more than probable that the problem comes from the expression within the tag.

If this works on Tomcat, carefully analyse the tab library, check against which JSP version it is developed and should run on, on which server you are and which JSP version there is supported.

In the end, if you are "lucky", you maybe will have determined that it is a bug in SAP's JSP processor. In this case, please open an OSS message to report it.

Hope it helps

Ooops, just saw you gave the info WAS 6.40, that means J2EE 1.3, and that again means JSP 1.2.

dimitri.

You have imported the class Constants. But you did not create an object of class Constants.

So accessing the Variable of Constants using Constants.SKILL_LIST_KEY return an error message. So you create an object of class Constant and use that object using the .(dot operator) to access the SKILL_LIST_KEY variable.

The Constants.java looks as following:

package .....;

public final class Constants {

public static final String SKILL_LIST_KEY = "skillList";

public static final String SKILL_TREE_KEY = "skillTree";

public static final String SKILL_LEVEL_BOX_KEY = "skillLevelBox";

public static final String SKILL_ID_KEY = "skillId";

public static final String SKILL_KEY = "skill";

}

That's not required to create an instance of this class.

Hi,

did you try to replace <%= Constants.SKILL_LIST_KEY %> with the actual value ("skillList")?

Some tags cannot be filled with java variables, i.e. they won't be translated to the actual values. In general, that is something you define in the tag settings, but I have had tags where the settings were correct but the still couldn't be substituted.

Regards, Astrid

What is the value of SKILL_LIST_KEY...
