Why all classes in javax.servlet.jsp are abstract?
Hi all,
I have two questions about how the package was designed:
1.) why all the classes in the javax.servlet.jsp are abstract? what is the benefits?
2.) why almost all the methods in the class, such as jspWriter, are abstract too? And we can use these abstract methods in the way we use "concrete" methods?
3.) the same thing for HTTPServlet class at javax.servlet package.
Thanks in advance

Thanks for the message. In fact, you don't need to reply to the message if you don't have the answer.
I suspect that this has something to do with the abstract factor design pattern. It allows each container engine to implement the detail based on its own specification. I just need some body to put more details on that.
Since this happens quite often if the J2EE library, it's good for us to understand why they do this way, and how we can use it in our design.

Javax.servlet.jsp.SkipPageException classes are not found
i'm using Sun java system application server plot form edition 8.2 to deploy

How can i overcome from this exception.Perhaps your version of the sun server is too old. SkipPageException exists since JSP 2.0 according to the javadocs.

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 - rutwikSurprise 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?

h5.MUTUSo 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. -
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!

Problem: package javax.servlet.jsp does not exist
I am a novice JSP programmer. My projects that use any javax.servlet classes are not seeing those at all. I am working with a group of folks using Java SE 1.5. (Note: I'm using Windows so the directory separator is "\")
What Used to work:
1. Nearly all my projects were working using Java version 1.6. These projects were developed as examples from Wrox and Apress books about JSP and Struts.
What has changed:
1. I un-installed the version 1.6 of JDK and JRE, as well as tomcat, netbeans, and all the associated libraries/jars.
2. I installed version 1.5 of JDK and JRE, as well as tomcat, netbeans, and all the associated libraries/jars.
3. I updated my JAVA_HOME, CATALINA_HOME, CLASSPATH, and PATH environmental variables. I made sure that the path to servlet-api.jar (in the tomcat common\lib) is included in the classpath.
What is wrong:
1. References to javax.servlet.* are not satisfied--they are flagged in the source code in NetBeans and I get compiler errors with any project containing those references. For example:
... package javax.servlet.jsp does not exist
import javax.servlet.jsp.*;
What I've found:
1. My CATALINA_HOME=C:\Java\Tomcat 5.5
2. My JAVA_HOME=C:\Java\jdk1.5.0_11
3. My CLASSPATH=.;C:\Program Files\QuickTime\QTSystem\QTJava.zip;%JAVA_HOME%\lib;%JAVA_HOME%\jre\lib;%JAVA_HOME%\lib\jsp-api.jar;%CATALINA_HOME%\common\lib\servlet-api.jar;C:\Java\logging-log4j-1.2.14\dist\lib\log4j-1.2.14.jar
4. My PATH=c:\wint\BIN;%JAVA_HOME%\bin;%JAVA_HOME%\jre\bin;%CATALINA_HOME%\bin;C:\MySQL\MySQL Server 5.0\bin;D:\MiKTeX 2.5\miktex\bin;C:\Perl\bin\;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\QuickTime\QTSystem\;C:\Program Files\Microsoft SQL Server\80\Tools\Binn\;C:\SFU\Perl\bin\;C:\SFU\common\;C:\Program Files\Lahey-Fujitsu Fortran\v7.1\Bin;C:\Program Files\Lahey-Fujitsu Fortran\v7.1\Win32\Bin
What I need:
1. I need to have some reference to the servlet classes satisfied in my configuration. Any help is appreciated.
thanks
jondrOh. I got some over-the-shoulder debug help.
My error was in the classpath specification:
The path: %JAVA_HOME%\lib\jsp-api.jar
Should be: %CATALINA_HOME%\lib\jsp-api.jar
That contains the javax.servlet.jsp.*
Thimk.

Hi,
I have an application which is executing properly in jboss 3.2.5 but as we are trying to upgrade the jboss version i am getting above mentioned error.
The application is deployed in jboss as an ear file and the ear contains one jar file that has been removed from the ear and still i am getting this error.
I am posting the full stack trace over here.

My guess would be that you have some of the servlet classes deployed with your application.
Yes.
Any jar files that contain the javax.servlet.* packages should NOT be part of a web application, but are intended to be on the server.
First up all there is no such jar files.
Common candidates:
servlet.jar
servlet-api.jar
j2ee.jar
All those jars are in lib directory of my app server. I have jsp-api and servlet-api.jar as i am using embedded tomcat 6 in jboss appsever.
Check the WEB-INF/lib directory of your web application to see that there are none of those there.
Nothing similar deployed in your ear file?I have extracted my application ear , jar and war then when i checked i found one jar file inside the war but in that no servlet*.jarr files. It is my application oriented files only. I have deleted this ar files and then i executedi am getting same error. Is there any way to find out the exact issue ????.

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.

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:
<!-- this tag uses c:set to set the property of a JavaBean -->
<c:set target="${questions}" property="topic" value="JSTL" />
<tr>
<td><c:set target="${'${'}questions}" property="topic"

Javax.servlet.jsp.JspException: Cannot find FacesContext
Hello All,
I was trying to create a simple JSF page (Welcome.jspx )(please find code bellow) .But it is always giving the following error:
javax.servlet.jsp.JspException: Cannot find FacesContext
The error appears though i am calling the page with the faces servlet (http://128.128.5.64:8989/GradeEntry/faces/Infrastructure/Welcome.jspx)!!
I have searched all possible forums on the Internet and tried their suggestions with no luck...My web.xml configuration contains the right Faces Servlet Mapping :
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>
Bear in mind that i can run from the project pages that are generated from Oracle Jheadstart...But i just can't run this welcome page that i've created with JDeveloper.
Please find bellow the code for Welcome.jspx:

You help is very appreciated!!Hi,
actually this mapping only identifies those requests to be handled by teh JSF servlet. Its not a redirect.
I see several namespace definitions in your page, but no taglib reference. Wondering how this is supposed to work
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
<%@ taglib uri="http://xmlns.oracle.com/adf/faces/html" prefix="afh"%>
<%@ taglib uri="http://xmlns.oracle.com/adf/faces" prefix="af"%>
I assume the next crash you will see is when you add JSF components to
<f:view>
<html>
<head>
<meta http-equiv="Content-Type"
content="text/html; charset=windows-1252"/>
<title>tt</title>
</head>
<body><h:form></h:form></body>
</html>
</f:view>
Note that mixing HTML elements with JSF is not a recommended approach

I've been trying to do the tutorials in a book titled Apache Jakarta-Tomcat as part of my introduction to JSP. I'm new to Java but do know the basics. I have on my machine Java 1.3, Java 1.4, Java FrameWorks 2.1 and Jython 2.1 on Win2000 Pro. So enough about my configuration. I have never worked with packages also.
I downloaded the files from the books site due to the fact I make a lot of typos when hand coding Java (I've become a pretty good debugger of my own code). But everytime I go to compile the *.java I get error messages. So below you will find HelloTag.java and beneath that the error messages that are thrown when I try and compile it. I tested other bits of *.java and have had no problem compiling them. Is there a JSP module I'm missing?
Am I doing something wrong or am I missing something from my configuration.
