Jsp classpath

hello every one,
i have designed a project in the JSP with some Javabeans classes, what when ever i m started my indexfile in which i m using some of my beans files. the error is coming that beans class is not found i.e is the beans is not instantiated. can anyone tell me how to set the classpath or where to keep my classes folder .
as i m using the tomcat server
the following tree structure is:
c:\tomcat\binary
webapps\examples\jsp\purejsp( is my folder which having the all the JSP files the image folder and the classes folder
tree structure of the my folder
purejsp
(contain all the JSP files )
contain the imgae folder ( having all the images )
contain the web-inf folder which having the classes folder having the all java beans classes
plz mail me how to set the class path asap
mail id is callyash@rediffmail com

You don't have a right dir structure. Did you set 'purejsp' in the context path in your server.xml? Make these changes if not,
1. Place all your jsps in webapps\examples\jsp folder.
2. Place web-inf and its subdirectories in webapps\examples folder.
3. Keep your other folder (images, srcs etc) in webapps\examples.
Because, context path will be already set for 'examples'. So, this examples must have web-inf dir. Now use the url, http://localhost:port/examples/jsp/your_jsp.jsp. This jsp can now identify the beans in web-inf\classes dir. You need to import those beans before you use them in your jsp.

Build JSP-structure problem in JspC

Hi,
I am trying to deploy my project and I need to compile JSPs and create WEB-INF directory and web.xml file.
My build environment:
Win 2000
Java 1.4.1
Tomcat 4.0.3
My problem is as follows:
I use an ANT script :
<java classname="org.apache.jasper.JspC" classpath="${jsp.classpath}" fork="yes" failonerror="yes">
<jvmarg value="-Dcatalina.home=${catalina.home}"/>
<arg line="-d ${jsp.path.precompile.src} -uriroot ${jsp.path.webapp} -webxml ${jsp.path.precompile}\web.xml -webapp ${jsp.path.webapp}"/>
</java>
I have an an compile this JSP structure:
-main_folder
- folder_1
- folder_2
- folder_2_1
- folder_3
- folder_3_1
- folder_3_1_1
but every time I start the script, the JSPs are compiled to JAVA in one default package. But I have in some subfolders the same JSPa like in the other folders ("index.jsp, error_page.jsp") and after compiling to JAVA this JSP are lost, because are overwritten from the other ...
In the old Tomcat 3.2 was OK!
I don't know how to tell to the JspC to use the folder structure as a package definition for the JAVA files.
Please help me !!!

Tis a defect in the way jasper/ant handles subdirectories in the packages that needs to be resolved. If you have your jsp files in a flat directory, you're fine. If you don't, you'll need this bug resolved: http://nagoya.apache.org/bugzilla/show_bug.cgi?id=4750
Please feel free to vote for it. :)
A workaround is to create a separate ant <jspc> task for each directory and subdirectory.

Error when compiling JSF JSP

I'm getting the following error when I try to compile an application containing a JSF JSP in JDeveloper 10.1.3. The error is:
Error: java.lang.NoSuchMethodError: javax.servlet.jsp.tagext.TagAttributeInfo.<init>(Ljava/lang/String;ZLjava/lang/String;ZZ)V
I've checked the files in the classpath and the TagAttributeInfo class is located in <install>/j2ee/home/lib/servlet.jar. I decompiled the class and it does have a constructor that takes (String, boolean, String, boolean, boolean).
The only change I made between when things worked and now is that I tried to add a JSF JSP that used the ADF classes. But once I started getting this compilation error, I removed the ADF classes from the project, so they shouldn't be causing any problems anymore.
Any ideas what's wrong?
Thanks

Hello,
May be that your classpath doesn't include that location ?
Have you tried to put the TagAttributeInfo.class file into your current folder
(or may be in ..\<your_project>\Classes\.. path ) ?
To check if your classpath does actually include your path, you could run:
<%@ page contentType="text/html;charset=windows-1252"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>Dummy JSP-CLASSPATH</title>
</head>
<body>
<%
out.println("<h1><em>JSP Showing your CLASSPATH</h1></em>");
out.println("<hr></hr><p>");
out.println(System.getProperty("java.class.path"));
%>
</body>
</html>
Hope this will help you.

Weblogic 6.0 jsp compile problem

          I'm having a problem with weblogic 6.0sp1 creating the java source files from a
          jsp file. The first 3 lines of the jsp are:
          <%@ page import="javax.naming.*"%>
          <%@ page import="java.util.Properties"%>
          <%@ page import="com.cicons.expenses.business.*"%>
          the first 2 imports work, but the 3rd does not. The compiler indicatesd the package
          is not found. The package com.cicons.expenses.business is located in a deployed
          ejb jar file targeted to the same server as the jsp. The jsp is in a war file
          also targeted to this server. Is it a requirement to create an ear combining the
          jar and war?


          Dave,
          The only way I have been able to successfully access an EJB from a JSP page in
          WLS 6 is to package everything up in their respective ear, war, and jar files.
          So I think that's what you need to do at the moment.

Help with JSP pre-compiling

We have a web application using Jboss4.0.5, jdk 1.6 and And 1.6.5, and now we try to do a pre-compiling as part of our build procedure.
That is the first time I am going to do a pre-comp of a major application, which includes about 1700 jsp files.
The directory tree of the application is as follows:
/project
    |--- > /web_pre-comp/pages/jsp ( it contains all the jsp files )
    |----> /web_pre-comp/WEB-INF ( it contains the web.xml file.)
    |----> /web_pre-comp/WEB-INF/tld ( it contains the tld files)
    |----> /web_pre-comp/WEB-INF/src ( it coutains the generated src file from jsp )
    |---->/web_pre-comp/WEB-INF/classes ( it contains the compiled classes once the jsp java files are generated.   )
    |----> build.xml ( the ant script )And there is my build.xml file looks like:
<project>
      <target name="pro.jsp.generate" depens="init">
       <java classname="org.apache.jasper.JspC" fork="yes">

Another side questions is when some java file are created from JSP, I see some "005f" included in the java file name, such as "inc_sup_princing_view.jsp" creats a

We have a web application using Jboss4.0.5, jdk 1.6
and And 1.6.5, and now we try to do a pre-compiling
as part of our build procedure. Hi Charlie,
According to your ant build script you're using Jasper compiler, but your web container is JBoss.
I know that Tomcat uses the Jasper compiler --- but I don't know if JBoss supports Jasper or not. Please check with JBoss if they support Jasper, if not they my support a different pre-compiler.
That is the first time I am going to do a pre-comp of
a major application, which includes about 1700 jsp
files.
The directory tree of the application is as follows:

The 005f is expected, it is for internal reference for the pre-compiler, nothing to worry about.

You must specify the full path to the loginBean or set the JSP classpath to the apache subdirectory. Also, when you set the session's value in the class, you must use the same name as the id in your JSP.
Ex: session.putValue("loginBean", loginBean);
then use:
<jsp:useBean id="loginBean"....
The two names must match.

By full path do you mean the absolute path to the directory where the .class file resides or the full path relative to %Oracle_Home% and is that full path used in the class parameter of the useBean statement?

8i Apache sessions on NT 4.0

When you use your browser's Back or Refresh buttons, the 8i Apache server may or may not create a new session rather than simply moving backwords in the history file or refreshing the current page. If you are trying to use session variable this becomes rather vexing. Is this "feature" inherant in Apache or in Oracle's implementation of Apache? And, is there anything that can be done about it?

8i Apache on NT 4.0

I have a bean. It's name is loginBean. It's class (loginBean.class) is located in \%Oracle_Home%\Apache\Apache\htdocs\csidb\Web-inf\classes (this is the Web-inf directory for the application). It is also located in \%Oracle_Home%\Apache\Apache\htdocs\Web-inf\classes, \%Oracle_Home%\Apache\jsp\Web-inf\classes and \%Oracle_Home%\classes. Any attempt to access this bean results in the following message:

The code calling/instantiating the bean is:
<jsp:useBean id="login" class="loginBean" scope="session" />
Why can this bean not be found? And, where should it be put to be found? And what device/tool should be used to put it there?

How to make the java files compile for a project created outside of Eclipse

Hi^^,
I have created a project outside of Eclipse. It has the following folders
1. config
2. source
3. WEB-INF
I want to execute the project on remote server. Will it compile automatically creating a new folder for .class files corresponding to the source folder or do i need to include a build.xml to enable the project to create a new folder for .class files. Also pls tell me how do I write this build.xml
Please advise.

Hi^^,
Actually I have created a project without using eclipse.
My source files are inside WEB-INF/source
Now I want to compile the files using build.xml so that I can create class files. I am using the following build.xml
<project name="jsp" default="all" basedir="./">
<property environment="env"/>
<property file="ArmorJSP.properties"/>

<property name="source" value="."/>
<target name="all" depends="copy, jspc, testservlet"/>

<target name="jspc">
    
    <java classname="weblogic.jspc" fork="yes">
      <arg line="-webapp ${APPLICATION_HOME} -compileAll -d ${APPLICATION_WEB_CLASSES} ${source}/*.jsp"/>
      <classpath>
        <pathelement path="${WL_HOME}/lib/weblogic_sp.jar;${WL_HOME}/lib/weblogic.jar;${ARMOR_HOME}/ARMORSecurity.jar;${ARMOR_HOME}/ARMORUtil.jar"/>
      </classpath>
    </java>
</target>

<target name="testservlet">
    
    <javac destdir="${APPLICATION_WEB_CLASSES}" srcdir="${source}" includes="*.java">
      <classpath>
        <pathelement path="${WL_HOME}/lib/weblogic_sp.jar;${WL_HOME}/lib/weblogic.jar;${ARMOR_HOME}/ARMORSecurity.jar;${ARMOR_HOME}/ARMORUtil.jar"/>
      </classpath>
    </javac>
</target>
<target name="copy">
    <copy todir="${APPLICATION_HOME}">
      <fileset dir="${source}">
        <include name="*.jsp"/>
      </fileset>
    </copy>
</target>
</project>I do not know how to compile the project using this build.xml
The motive of doing all this is to understand how is Eclipse doing the build project step. I simply cannot find any build.xml inside any of my projects created in Eclipse however when right click on the project and choose build project, it compiles excellently. ???

Restarting Apache server (Password?)

I can't edit my httpd.conf file; every time I restart my servers, my edits vanish.
Someone suggested I restart the Apache server by typing the following into Terminal:
sudo apachectl -k restart
So I did, and I get the following error:
/usr/sbin/apachectl: line 90: 17349 Bus error: 10 $HTTPD $ARGV
Can anyone tell me what this means and how I can fix it?

Hi,
By default, the Oracle JSP class loader that comes with the Oracle JSP Container will automatically reload a class in the Oracle JSP classpath whenever the class file or JAR file has been modified since it was last loaded.
The JSP container checks whether the last-modified time of the page implementation class file is older than the last-modified time of the JSP page source file.
However to enable dynamic loading, remember that classes must be in the JSP classpath, not the system classpath, to be dynamically reloaded. If they are in the system classpath as well, the system class loader may take precedence in some circumstances, possibly interfering with JSP automatic-reloading functionality.
Also just check that you have the latest version of ojsp.jar (Oracle JSP Container implementation)

Abhinav

Automate the build process

          I found that it needed access to the .tld, web.xml, and weblogic.xml files before

Import CLASSPATH in JSP

Hi all,
I am following a guide to install an JSP application on Tomcat.
The third point is:
Confirm JAR Files are Included in CLASSPATH
Please ensure that the .jar files in the WEB-INF/lib/ directory of your web
application are included in the CLASSPATH for your application.But I don't know how to do it (I'm not an expert of JSP).
Someone can help me to add the code line(s) in a such way that I can include the WEB-INF/lib/ in the CLASSPATH of my application.
Thanks
Enrico

I've understood now. The google's code,
<td>
         <iframe name="identity_provider" src="./ProcessResponseServlet"
          width="100%" height="100%" frameborder="1"></iframe>
</td>is wrong. I've just replaced this with:

          width="100%" height="100%" frameborder="1"></iframe>
      </td>But now the problem is always the same because inside this file there is:
<form name="ServiceProviderForm" action="./CreateRequestServlet" method="post">

<input type="hidden" name="returnPage" value="service_provider.jsp">

<%
      String error = (String) request.getAttribute("error");
       String authnRequest = (String) request.getAttribute("authnRequest");
      String redirectURL = (String) request.getAttribute("redirectURL");
      if (error != null) {
      %>
        <p><center><font color="red"><b><%= error %></b></font></center><p>

        <p>You can now review the generated SAML request before submitting it to the identity provider.</p>
        <p>As noted in the <b>Pre-Transaction Details</b>, when you install this application, it will send SAML authentication requests to the <b>ProcessResponseServlet</b>, which is included in the sample code package.</p>
        <b>Generated SAML XML</b><p>
        <input type="hidden" name="redirectURL" value="<%=redirectURL%>"/>
        <div class="codediv"><%=RequestUtil.htmlEncode(authnRequest)%></div>
        <p><center>
        <input type="button" value="Submit AuthnRequest"

        </center>
     <%
     %>And there is the file "CreateRequestServlet.class" in the "WEB-INF/classes/servlets" and the web.xml maps also this file.
But when i press the button "Generate SAML Request", I have the usual error:
HTTP Status 404 - /CreateRequestServlet/CreateRequestServlet
type Status report
message /CreateRequestServlet/CreateRequestServlet
description The requested resource (/CreateRequestServlet/CreateRequestServlet) is not available.

CLASSPATH problem, deploying JSP app without right to modify classpath...

I want to deploy a JSP web app to apache server with JRun for running JSP, but I don't have the permission to copy the required library files to the classpath, nor modify the classpath to append my application's path. Is there any way to workaround? Thank you

Well, thanks for the tip. The answer is yes and no. Yes, the jar is in my classpath, but no the lib directory containing the jar is not included in the dist directory when I clean and build the project. This only happens when I include either the JavaHelp jars or just the jh.jar (which should be all I need) in the classpath. When I read the manifest file, it's clearly looking for /lib/jh.jar, but the directory does not get created on build (whereas, the lib directory is there if the JH jars are not included).
Makes no sense to me. Any idea as to what's happening here? The help system works great in the IDE.
Thanks for your help.

Classpath and JSP

HI
I had a question regarding connection of JPS with Oracle8i.
I have created a jsp page (Firstpage.jsp) for connecting to the database, Oracle. (I have provided the code at the bottom).
I am using Tomcat 3.3.
Everytime I run this page , I get an error: Class OracleDriver not found. What should I do to connect to oracle?
My questions are as follows:
1) In order to connect to the database what should be the classpath set - (what i have rite now in my classpath is .;C:\Tomcat\lib\common\servlet.jar;C:\Tomcat\webapps\ROOT\WEB-INF\classes)
2) Do i Have to make any changes in the server.xml file or tomcat-modules.jar file? If so wot changes do I have to make. Or is there any other file
3) Like java where I add classes12.zip and nls_charset12.zip to the classpath while connecting tothe dbs , Do i have to do the same ? But where should the classes12.zip and nls_charset12.zip files be ? ie. should they be in C:\oracle\ora81\jdbc\lib or should they be copied to another folder ?

I hope somebody answers my queries, coz im having sleepless nights
thanks

One way is to copy classes12.zip into:
<JAVA_HOME>jre\lib\ext
and setting the classspath to point to it.
Another way is to set the classpath to the Oracle's
directory where you have the driver:
oracle\ora81\jdbc\lib
No No NO!
Tomcat does not look at your classpath. It completely ignores it.
As far as Tomcat is concerned its class path is
web-inf/classes (with .class files in it)
web-inf/lib (with .jar files in it - note it will not read .zip files)
Tomcat lib directories.
For Tomcat 3.3, go here to read all about it.
