Deployment error - Missing class: javax.servlet.jsp.jstl.core.Config

Hi,
We are using JDeveloper 10.1.3.0.4(SU5) on windows for development of ADF application. We need to deploy the developed application onto Oracle Application Server 10g (10.1.3) which is running on Solaris. We are using BC4J, WAR and EAR deployment profiles in jdeveloper to create the .war and .ear files.
If I deploy the generated ear on a standalone OC4J server install on my windows PC, it works fine.
Now when I deploy the generated .ear file onto the Oracle Application Server 10.1.3 through Application Server Control interface and then try to access the jspx pages under our application we are getting following error:
oracle.classloader.util.AnnotatedNoClassDefFoundError: Missing class: javax.servlet.jsp.jstl.core.Config Dependent class: com.sun.faces.application.ViewHandlerImpl Loader: accaweb.web.accaweb:0.0.0 Code-Source: /oracle/app/oracle/product/10gas3/j2ee/home/applications/accaweb/accaweb/WEB-INF/lib/jsf-impl.jar Configuration: WEB-INF/lib/ directory in /oracle/app/oracle/product/10gas3/j2ee/home/applications/accaweb/accaweb/WEB-INF/libThe missing class is available from the following locations: 1. Code-Source: /oracle/app/oracle/product/10gas3/j2ee/home/default-web-app/WEB-INF/lib/jstl.jar (from WEB-INF/lib/ directory in /oracle/app/oracle/product/10gas3/j2ee/home/default-web-app/WEB-INF/lib) This code-source is available in loader default.web.defaultWebApp:0.0.0. at oracle.classloader.PolicyClassLoader.handleClassNotFound (PolicyClassLoader.java:2051) [oracle/app/oracle/product/10gas3/j2ee/home/lib/pcl.jar (from system property java.class.path), by sun.misc.Launcher$AppClassLoader@1482257]
I have confirmed that the .war file inside the .ear file does contain the jstl.jar file under WEB-INF/lib folder. And the jar file does contain the class 'javax.servlet.jsp.jstl.core.Config'
As a workaround, I found that if I copy the jstl.jar file from default-web-app to my application web-inf/lib folder, things start to work fine. ie copy from: '/oracle/app/oracle/product/10gas3/j2ee/home/default-web-app/WEB-INF/lib/jstl.jar'
to: '/oracle/app/oracle/product/10gas3/j2ee/home/applications/accaweb/accaweb/WEB-INF/lib/'
– or –
Another workaround is to add the '/oracle/app/oracle/product/10gas3/j2ee/home/default-web-app/WEB-INF/lib/jstl.jar' file in the classpath for my web application through Application Server Control setting page.
Now both of these workaround needs us to perform additional post deployment steps which should really not be required since the jar files is included in the project.
Has anyone faced this issue? Any pointers in this respect will be a great help.
regards - rutwik

Surprise Surprise !
I just tried deploying the file via uploading it from the Application Server Control UI and it worked fine.
Till now, I was ftp'ing the ear file from my PC to the server on which Oracle AS is running and was telling Application Server Control to pick form that uploaded location.
I am still not clear on why it works with HTTP upload and not via the FTP upload?
cheers - rutwik

JSTL javax.servlet.jsp.jstl.core.Config strange lookup

Hi everyone !
Could someone explain me this code in the class javax.servlet.jsp.jstl.core.Config :
public static Object get(PageContext pc, String name, int scope) {
switch (scope) {
     case PageContext.PAGE_SCOPE:
     return pc.getAttribute(name + PAGE_SCOPE_SUFFIX, scope);
     case PageContext.REQUEST_SCOPE:
     return pc.getAttribute(name + REQUEST_SCOPE_SUFFIX, scope);
     case PageContext.SESSION_SCOPE:
     return get(pc.getSession(), name);
     case PageContext.APPLICATION_SCOPE:
     return pc.getAttribute(name + APPLICATION_SCOPE_SUFFIX, scope);
     default:
     throw new IllegalArgumentException("unknown scope");
Why adding a suffix when calling PageContext.getAttribute(String, int) ?
This could lead to potential problems... For example, in my web application I want to share a single ResourceBundle for each JSP page and I would like to use <fmt:message/> tag to resolve my messages.
For this purpose I added a LocalizationContext in my servlet context attribute in its init method:
ResourceBundle bundle = ....
LocalizationContext context = new LocalizationContext(bundle);
servletContext.setAttribute(Config.FMT_LOCALIZATION_CONTEXT, context);
Thus, the <fmt:message/> will be able to resolve the messages from this LocalizationContext...
Unfortunately, this will never happen because the implementation of this tag call somewhere Config.find(PageContext, String) that will call the Config.get(PageContext, String, int) method....
A quick fix would be to replace the name of the servlet context attribute :
servletContext.setAttribute(Config.FMT_LOCALIZATION_CONTEXT + ".application", context);
Could someone tell me if it is a bug ? A bug of the Message tag implementation ? A bug in JSTL code ? Or am I doing all wrong ?
Note : I'am using a servlet 2.4/JSP 2.0 compatible application with the jstl 1.2 core library and the jakarta standard 1.1.2 implementation library. I'am using Jetty to test my application with Jasper as the JSP compiler...

This is an internal decision made by JSTL as to how it stores its configuration values.
The reason they have given here for the suffixes being added is to treat the four scopes as different namespaces, so that there can be no confusion between them.
I'd say your mistake is trying to set this value into the attribute space yourself rather than using one of the defined interfaces for JSTL to do it - in web.xml, or using the Config class.
I guess that would make your code
Config.set(servletContext, Config.FMT_LOCALIZATION_CONTEXT, context); Using their interface for setting this attribute adds the required suffix automatically.

ClassNotFoundException: javax.servlet.jsp.jstl.core.LoopTagStatus

In JSF2, writing facelets I tried to use <ui:repeat> tag instead of <c:forEach> - JSTL tag.
I get -> java.lang.ClassNotFoundException: javax.servlet.jsp.jstl.core.LoopTagStatus
Here is my facelet snippet ...
<ui:repeat value="#{historyCenterManagedBean.purchases}" var="order" >
         <tr>
             <td>
                #{order.totalPriceBeforeDiscounts}:
             </td>
             <td>
                #{order.person.firstname}
              </td>
         </tr>
    </ui:repeat>I am not sure why am I getting it. Any help is appreciated.

Hmm, Thanks Ryan. I am still confused.
I am not clearly understanding why would c:forEach fail? And this is happening after the nightly build jar of 20091216
for example this is we have:
<c:forEach var="partner" items="#{contentPartnersManagedBean.allAuthorizedContentPartners}" >
    <tr>
          <td><a href="#{contextPathManagedBean.contextPath}/about_us/providers_detail.jsf?pID=${partner.partnerId}"
                 class="# {portalSkinManagedBean.contentPortletSkin.normalTextStyle}">${partner.partnerName}
                 </a>
          </td>
   </tr>
</c:forEach>This is the exception:

Missing artifact javax.servlet.jsp:jsp.api:jar:2.1 Eclipse error

When I try to UPDATE my Maven project ( Chapter 8 - Using JSP with AEM 6.0 ) after I updated my main pom.xml with the javax.servlet.jsp dependancy, I get the following error :Missing artifact javax.servlet.jsp:jsp.api:jar:2.1
I even tried to compile from command line using mvn compile and get the same error :

If I look at my .m2 dir, I can see that it attempted to get the jar, but it wasn't able to grab it :

Hi Billy,
Try changing the URL from (http://repo.adobe.com/nexus/content/groups/public/) to (https://repo.adobe.com/nexus/content/groups/public/), i.e. add the https.
That should do it. Let us know if it doesn't work.

So why didn't you think that the JSP forum here wasn't a good place to ask JSP questions like this one?
You can use <c:for-each> with a List. That's how it's designed. I don't understand why you say you can't. Perhaps you were confused by the SQL tags in JSTL. But anyway, you should just return a List from your EJB and forget about using obscure internal JSP classes.

Class javax.servlet.jsp.PageContext compilation error

During Rebuild/compilation of the JSP files inside JDeveloper, I am encountering the compilation error "Error(548,78): method handlepageException (java.lang.Throwable) not found in class javax.servlet.jsp.PageContext. When I developed the same application under IBM WSAD, I included the library com.ibm.servlet.jar and will take care of it. Which Oracle Jdeveloper lib I need to include? Since it is a servlet library error, I tried to include the Oracle "Servlet APIC Classes" but it didn't fix the problem. Thanks in advance!

hmmm... i had a look and it seems that what you are trying to "import" is actually in a package... instead of import try:
package javax.servlet.jsp;you may need to go download this "package" and complile it in the directory you are working in.
my advice: try the above statement (which does compile for me), if it doesn't work, you will need to find the source code for this package and compile it just like you do any other source code.
hope this helps.

ClassCastException: javax.servlet.jsp.jstl.fmt.LocalizationContext

today i had the following exception, which blows my mind away. what can be wrong?
java.lang.ClassCastException: javax.servlet.jsp.jstl.fmt.LocalizationContext
     at org.apache.taglibs.standard.tag.common.fmt.BundleSupport.getLocalizationContext(Ljavax.servlet.jsp.PageContext;)Ljavax.servlet.jsp.jstl.fmt.LocalizationContext;(BundleSupport.java:127)

well the fact is that the JSPs are 100% correct. i'm migrating some legacy project, which builds, deploys and runs in its old state with no errors at all (and the old state is current PRO, so every bit of code is supposed to be correct). hence i presume it's not the JSPs that are wrong (because i never touched them), that's something else, probably the configuration of things, or conflicts between container libs and webapp libs, or sort of like that.
so if this error doesn't ring a bell, then i'll try to fiddle around, i thought maybe that's something "famous" :).

Javax.servlet.jsp.jstl.sql.Result and arraylist

Hi,
I try to explain my problem, I have posted in another section of forum, but perhaps this is a better place:
I'm trying to use MVC model, so I call an EJB from a servlet which returns me a javax.servlet.jsp.jstl.sql.Result object (this derive from a resultset of a query) and then I make this available to a jsp page.
I've choosen to return an javax.servlet.jsp.jstl.sql.Result object because I'd like to use this syntax:
<c:forEach var="profiloString" items="${listaProfili}" >
${profiloString.anything}
</c:forEach>Now I need to put my listaProfili object in session and permit users of my application to add and delete items from it. Finally I will update my database with the new data from listaProfili object.
If listaProfili is an arraylist I can easily add or delete item from it, but if it is a javax.servlet.jsp.jstl.sql.Result I don't know how I can do this.
If I return an arraylist object instead of an javax.servlet.jsp.jstl.sql.Result object, I can't use "<c:forEach ..." syntax.
Can anyone help me?
Thanks.

So why didn't you think that the JSP forum here wasn't a good place to ask JSP questions like this one?

Hi All,
          I'm a System Engineer. My application code in Java and using JDK 1.3.1.

          I already downgrade for iSeries V5R3 to JDk 1.3.1.
          Did Weblogic 6.1 support IBM iSeries V5R3?
          Do you have any ideas?
          Thank you.

hi siewmun ,
          weblogic 6.1 does't support IBM iSeries V5R3 .
          IBM iSeries V5R3 is supported by IBM products mostly.

Javax.servlet.jsp.el.ELException: Attempt to coerce a value of type

I've written a web service to retrieve informations from the database based on a client's criteria. The service endpoint is the following:
public WSMissionBean getProfiles( WSMissionBean mission, WSProfileBean profile ) throws java.rmi.RemoteException;
The WSMissionBean object is as follows:
public class WSMissionBean implements Serializable {
private WSProfileBean[] lstProfile;
private WSProfileBean[] lstProfileMoinsQualifie;
private WSProfileBean[] lstProfileByPoste;
private WSProfileBean[] lstProfileByCompetences;
And WSProfileBean is an object containing just simple data types. The whole idea is to have an object which, besides the criteria entered by a client, holds differents arrays, each of which answers a certain number of criteria required by the client.
The service is deployed correctly, and I can access it, from a stand alone simple program, to retrieve data from the database as expected. The big problem is when I try to show the results in a JSP page! And the error message is:
javax.servlet.jsp.el.ELException: Attempt to coerce a value of type "[Lclient.WSProfileBean;" to type "java.lang.reflect.Array"
My JSP pages are as follows:
<table border=0 cellspacing=1 cellpadding=3>
   <%-- sessionScope.mission.profiles contain data return by the web service, and gr:listRenderer is a tag file to show the result--%>
   <gr:listRenderer list="${sessionScope.mission.profiles}" />
</table>
And in the tag file, I have
<%@ attribute name="list" required="true" type="java.lang.reflect.Array" %>
<c:forEach var="profile" begin="0" items="${list}">
     <tr>
     <c:set var="profileId" value="${profile.id}" />
     <c:if test="${profile.selected}" >
          <td bgcolor="#0099FF"><input type="checkbox" name="${profileId}" checked="checked"/></td>
     </c:if>
     <c:if test="${!profile.selected}" >

I've been searching desperately for days on the web for an answer, but to no result! I appreciate if someone can give me some advice, explanation... Thanks in advance

java.lang.reflect.Array is NOT a class which represents an array.
It is a class that provides several static methods for using on arrays.
The type of your attribute should be Object[] - an array of Objects.
That will be compatible with an array of any sort of object (but not with an int[] for instance)
<%@ attribute name="list" required="true" type="java.lang.Object[]" %>

Package javax.servlet.jsp does not exist.

dear all!
I've one program which import javax.servlet.jsp.* as one of the package to be used in
the program, and I am using j2sdk 1.4.0_01 to compiled it.
However I got this error message : package javax.servlet.jsp does not exist.
Where does it wrong?.
error message like :
logisticslib.java:6: package javax.servlet.jsp does not exist
import javax.servlet.jsp.*;
^
logisticslib.java:201: cannot resolve symbol
symbol : class JspWriter

You need a J2EE implementation, I recomemend Tomcat, you also need to put the .jar w/ the implementation in in your classpath.

Error in compiling: file javax\servlet\jsp\PageContext.class not found

Hi,
i'm getting an error when I'm trying to compile an java file. The error is as follows:
cannot access javax.servlet.jsp.PageContext
file javax\servlet\jsp\PageContext.class not found
Isn't the javax package included in jdk? I've installed jdk 1.3.1_03 and j2re1.4.0_02. Shouldn't this PageContext.class be automatically loaded when i've installed jdk?
I'm getting desperated! I've tried almost everything: i've changed the classpath, moved the directory of the java file I'm trying to compile over and over but i'm getting no success!
Any help is very welcome!
Thankx,
Nuno.

     org.apache.taglibs.standard.tag.common.core.SetSupport.doEndTag(Unknown Source)From the stacktrace, it appears to be from a <c:set> tag.
Invocation target exception would meant that an error was encountered calling the setter.
That would focus on this part of the code:

<c:set target="${questions}" property="topic" value="JSTL" />
<tr>
<td><c:set target="${'${'}questions}" property="topic"
value="JSTL"/>
</td>That nesting of ${ } inside ${} looks dodgy to me. What is it you are trying to achieve?
