Javabean class not found by jsp page

I have created one bean which has setFunctionId(String) and getFunctionId() methods. I put the class files at /weblogic/myserver/serverclasses directory. While I am accessing the .jsp page it is telling "Thu Aug 03 15:46:16 EDT 2000:<E> <ServletContext-General> Servlet failed with Ex

Thank you for your valuable feedback duffymo. Could
you explain a little what you mean by "Putting .class
files in the Tomcat examples directory is a really bad
idea in the long run". Also, could you direct me to
some source where I can find more information on
creating WAR files keeping in mind that I am a
beginner.
Thanks.But putting your web apps into WAR files, you can have quite a few different web apps running on the tomcat server as compared to if u place your files into the default webapp folder, u can only have 1 web app running.
For creating WAR file, the easiest way is to use an IDE like JBuilder.

Class not found - from jsp sub-directories

Hello:
Main-Issue:
- I have some java-class files in the \<my-web-app>\web-inf\classes directory. These classes do not belong to any packages.
- I have some jsps in the \<my-web-app>\ directory and also in some sub-directories in the \<my-web-app>\ directory. Example: \<my-web-app>\test\index1.jsp.
- The jsps in the \<my-web-app>\ directory can invoke the classes in the \<my-web-app>\web-inf\classes directory with no issues. But, the jsps in the sub-directories CANNOT see the classes in the \<my-web-app>\web-inf\classes directory. I get a "class not found" error. (this is just in oc4j).
First of all, just a background to the issue:
- I am trying to port a web application from JRUN to OC4J.
- I want to do this with minimal changes to the existing code.
- The application has been running on JRUN for a while. I only see the above mentioned error (class not found) error when trying to run it on oc4j.
- As a test, I created my own test application to verify:
(-) I wrote a simple java class (test.class) with no package and placed it in the web-inf\classes directory
(-) I wrote a jsp file (index.jsp) to invoke test.class. I placed the jsp at the top-level directory of the web-app.
(-) I wrote another jsp file (index1.jsp) to invoke test.class as well. I placed that jsp file in a sub-directory in the top-level directory of the web-app.
(-) index.jsp worked without any problems. index1.jsp gave the "class not found" error.
(-) As another test, I then modified the class to be in a package (com.benny). I then changed the jsps to call "com.benny.test" rather than just "test". This time, both index.jsp and index1.jsp worked fine.
So, I guess my question is, do these classes have to be in a package? I am trying to avoid having to make a lot of changes to the app. If they do have to be in packages, then I have re-compile a lot of class files, add import statements to jsps, etc.
Any help/suggestion would be appreciated.
Thanks,
Benny

So, I guess my question is, do these classes have to be in a package?Answer: yes.
As of Java1.4, classes in the "unnamed" package were no longer accessible.
What version of java were you running with JRun?
What version are you running with OC4J?
Read all about it here:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4361575
If you have to repackage the classes, the IDE Eclipse has excellent support for refactoring, and wil let you put classes into packages with a minimum of fuss.

Tag library 'not found' in jsp page. why?

I'm having a big problem with jsp/tag libraries using oc4j. One
particular
tag library is not being 'found' for some mysterious reason. The
particulars follow:
kwTags.jar is the jar file containing the tag classes. It definitely
exists in WEB-INF/lib directory.
tld def. in web.xml:
<taglib>
<taglib-uri>/kw</taglib-uri>
<taglib-location>/WEB-INF/tlds/kwTagLib.tld</taglib-location>
</taglib>
The tld file definitely exists in the /WEB-INF/tlds directory.
The definition of the tag lib at the top of the kwTagLib.tld follows:
<taglib>
<tlib-version>1.0</tlib-version>
<jsp-version>1.2</jsp-version>
<short-name>kw</short-name>
<uri>/kw</uri>
<display-name>kwTagLib</display-name>
<small-icon></small-icon>
<large-icon></large-icon>
<description></description>
The tag reference in jsp page is:
<%@ taglib uri="/WEB-INF/tlds/kwTagLib.tld" prefix="kw" %>
The development environment is Eclipse Workbench 5.1.0 and Eclipse
v.3.2.1
JDK is: j2sdk1.4.2_04
All other tag libs (Struts v.1.3.5) are found and work correctly. This
is the only tag library that
a problem.

By the way, your declaration of taglib in web.xml can be deleted if you are not using that taglib-uri "/kw" in your jsp.

IUser class not recognized in JSP page

Hi All,
I am trying to get the roles of the user logged in. I am getting the user name by using
IUserContext userContext = request.getUser();
String firstName = userContext.getFirstName();
How to get the roles of the user. When i am using IUser it is giving errors. I even included com.sap.security.api.jar file. But still it is not working.
Can somebody help me sort this problem.
Thank you,
Surendra.

Hi Surendra,
You can convert your IUserContext to IUser like this:
com.sapportals.portal.security.usermanagement.IUserFactory userFactory = WPUMFactory.getUserFactory();
com.sapportals.portal.security.usermanagement.IUser eP5User = userFactory.getEP5User(userContext);
Use IRoleFactory.getRolesOfUser(eP5User.getUniqueID(), true); method to get all assigned user roles recursively.
IRoleFactory roleFactory = UMFactory.getRoleFactory()
roleFactory.getRolesOfUser(eP5User.getUniqueID(), true);

9.0.3 Preview - Class not found error after including jsp:useBean

Hi,
I got a Java.lang.NoClassDefFoundError while compiling a JSP Page, after including a simple web bean as follows:
<jsp:useBean id="catviews" scope="request" class="CategoryView" />
<jsp:setProperty name="catviews" property="*" />
somewhere within the HTML page...
<%= catviews.getCategory() %>
The JSP page without the bean compiles fine and the Javabean itself compiles without error. The bean class is where JDev automatically puts it (i.e in a sub-directory of the classes directory within the project) and JDev does not raise any error on that JSP Page before compiling.
The error seems to point to the first line of the page, to the directive of the JSP page:
<%@ contentType="text/html" ... %> which is apparently harmless. What can be wrong ?
Thanks for your reply.

'Class not found' means 'Class not found' , the class you are referencing is not in your project's classpath. You should make sure your project's classpath point to the location where this class is deployed to. This could be a directory or a .jar file. You should also include the package name as part fo the class.

JSP-class not found

My server already working properly in internet.It's a travel agent site.there after i include one more page for audio guide which is JMF with in the applet and it is plugin to my jsp page.It's work very fine in my local system.my server is Tomcat .But if i hosted to our server means it's giving applet class not found exception.
It is already having com package ,now i include my jmf package wol to it.
My root directory of this class file is
web-inf/classes/wol/PlaySongs.class
My server doesn't have JMF pack so,i just copy JMF.jar and Sound.jar to my web-inf/lib/ folder.and also to my server folder like tomcat/common/lib/ .Now i restart my server it's giving applet class not found exception.but it's working fine in local system.
I have using following jsp code.
<body>
<%
String fname = "file:" + request.getRealPath("AudioF") + "/button-1.mp3";
%>
<jsp:plugin type="applet" code="PlaySongs.class" codebase="/wol" width="300" height="20">
<jsp:params>
<jsp:param name="file" value="<%=fname%>" />
</jsp:params>
<jsp:fallback>
<p> Unable to start Plug-in. </p>
</jsp:fallback>
</jsp:plugin>Any one help me.
Regards
K.Suresh

the codebase should be a path into the webdir, not the WEB-INF dir. Your browser needs to be able to reach the applet class like any other resource.
My server doesn't have JMF pack so,i just copy JMF.jar and Sound.jar to my web-inf/lib/ folder.and also to my server folder like tomcat/common/lib/If you are already copying it to your common/lib folder, you don't need it in the lib folder of your webapp.

Class not found when I run JSPs

I set up and can run JSPs in iPlanet 4.1 SP9 on NT. But if I use anything
such as Date() I get a Server Error and a Class Not Found in the error log.
Can someone tell me how to confire where the .class and .jar support files
go, or where do I put them. In the JDK install directory or in the iPlanet
install directory.
Thanks, Gary

Something to note, you must have superuser priveleges to run ibconf.
Check out this document about installing a PCI-GPIB on a Solaris machine. There is a section in it on page 9 about configuring the software with ibconf.
If you still have problems after reading through this repost.

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.

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.

Class not found error on Firefox browser

Requirement:-
We have Apache server on the top of a tomcat container where we have deployed application Webnow. This application will provide SSO to another application Imagenow. The requirement is we have to authenticate and authorize a user based on the client certificate which will be installed on the client side browser.
Issue:-
We have achieved the requirement for the browser IE. But for browser Firefox ,we are getting an exception "Class not found". Basically an applet class from the jar is not getting loaded on the Firefox.
Further investigating on this we came to conclusion that Firefox is not able to read the SSL certificate.
In order to eliminate this, we have imported the client certificate in java console as well. After this step, we were not getting "ClassNotFoundException" in FF. But right now, user is getting prompted for certificate/keystore password each & every time while trying to login onto the application (both in IE & FF).
So, we are trying to find ways to remove class not found exception without importing client certificate to java console. Also , is there any way to eliminate the authentication pop up for keystore (though we might not go for this approach as it will be very difficult to manage Java console for end users). Need your urgent help on this issue.
Attaching stack trace of both the browser and screenshot of keystore authentication pop-up . FF_Issue_stacktrace.docx is one when we were getting "class not found exception" and IE_Stacktrace.docx is one for successful case.

We have a similar set up where we have a web app and an applet in a JSP page. You have to put your applet classes up above WEB-INF. So, if your structure for your webapp was:
tomcat/webapps/mywebapp
you'd want your classes under mywebapp instead of webapps/mywebapp/WEB-INF. In your case, if I read your package structure right, you'd want a Log directory under webapp that contains your LogApplet.class file.
I hope this works for you!

Hi here is solution,
later I will put a project for this solution, right now I am really busy with ADF implementation.
core changes is to solve my problem:

    while ((nread = is.read(buffer)) != -1) {
      os.write(buffer);

Servlet class not found error deploying a WAR on Web Logic Server 8.1

I'm re-deploying an updated web application to a web logic server, but when I navigate to the login page of the web application to test it, I get a class not found error for my login servlet. I have both the web.xml and the weblogic.xml descriptors in my WEB-INF directory, and all of my compiled classes are in the WEB-INF/classes directory, is there something else I'm missing? Any help would be much appreciated.

Thanks for the response. Here's the web.xml file:
<?xml version="1.0" ?>

None of the classes are in a package (I know it's not the best idea, but I didn't write these, I'm just doing some updates). So the file structure is pretty much just WEB-INF/classes/
At the moment I've got a fix by just putting the entire project (not in any sort of archive) on the server itself instead of deploying it as a WAR, any thoughts on why the WAR isn't working would be much appreciated though.

Not certain but try putting the classes folder in your classpath:
D:\Apps\Apache\Tomcat4.0\webapps\ROOT\WEB-INF\classes\

APPLET.class not found error on explorer!! need solution URGENTLY!!!

Hi,
I am calling my applet from a jsp and trying to run it on the internet explorer but I am getting the following error:
load: class /WEB-INF/classes/Log/LogApplet.class not found.
java.lang.ClassNotFoundException: .WEB-INF.classes.Log.LogApplet.class
My Explorer version is 6.0 and I am using Plug-in: Version 1.4.1_05. Why do you think it cannot find the class? it is located under the specified directory which is:
/Web Content/WEB-INF/classes/Log/LogApplet.class
and my jsp which is calling my applet is located under:
Web Content/Login.jsp
this is a very urgent problem!! could you please help me? I will appreciate your help so much.
Thanks,
Sofia
here is how I wrote my jsp:
<jsp:plugin type="applet"
code="/WEB-INF/classes/Log/LogApplet.class"
width="600"
height="620"
>
<jsp:params>
</jsp:params>
<jsp:fallback>
<p>Unable to start plugin.</p>
</jsp:fallback>
</jsp:plugin>
...

I'm having the same problem...however my applet is located outside of the web-inf folder. the web-inf folder is only for servlets. applets can't be recognised inside it since that folder is for server-side application while applets are meant for client-side.
i put my applet into a separate folder in the root directory of the webapp but it's generating a security error when i call it using a jsp page. so far the only way i got around it was specifying the entire codebase using localhost...but it's not a pretty good way of doing it.
any ideas anyone?
