Package related: servlets - jsp
Hi!
I have built a WebApp with servlets only - now I want to add a few JSPages. but I can't instantiate any classes or call any servlets' (static) methods, because they are not public, but only visible to the package all the servlets of my WebApp belong to!!!
Can I make a JSP join a package???
Or what do you recommend?
any hint appreciated
thanks
michi
Any custom defined methods that are common to all servlets/JSPs should not be coded in any one servlet rather they should be defined in a separate file which exposes these methods as public for all to share. Note that I said custom defined methods. These are methods that do not belong to the standard servlet class and are not part of the class hierarchy. In other words, methods that you created to extend functionality such as methods that obtain database connections, write to log files, or maintain generic audit trails. I would consider breaking these types of methods out of existing servlets to improve the overall design of the application.
If this is not possible then I would suggest creating a type of mediator object that exists in the same package as the servlets and exposes the necessary methods as public members and delegates all processing to the methods in the servlets. In other words, class mediator lives in the custom.java.servlet package and defines public methods foo() and bar(). These methods call foo() and bar() in custom.java.Foo and custom.java.Bar servlets respectively. This is not the best overall design however.

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.

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?.

Javax.servlet.jsp does not exist
Hi,
I'm having difficulty compiling a simple java class. The eror message is on an import javax.servlet.jsp statement. The specific error message is:
package javax.servlet.jsp.tagext does not existThis is just a simple tutorial class from a J2EE book. I am confused if the servlet-api.jar file is what it needs and it isn't finding it, or if I need another file, perhaps the servlet.jar? (What is the difference between the two?)
My OS is Windows/XP
My java version is 1.4.2_06
Servlet-ap.jar exists in C:\jakarta-tomcat-5.0.28\common\libMy CLASSPATH is C:\jakarta-tomcat-5.0.28\common\lib\servlet-api.jar;C:\j2sdk1.4.2_06;My JAVA_HOME variable is C:\j2sdk1.4.2_06My Path is %JAVA_HOME%;%JAVA_HOME%\bin;Thank you in advance.I sometimes use a bash shell under "cygwin" on Windows XP for development, compiling, etc. The following example file would allow you to compile in a bash shell environment:

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!
Thankx,

Hello All,
A few problems here
1. My classpath doesnt seem to work.:
.;"C:\Program Files\Apache Software Foundation\Tomcat 6.0\lib\servlet-api.jar"
2. As a result, i get many errors in my simple code, but there are still a few that are not related to javac not recognizing the servlet api.
I also tried setting the classpath at the command line (event hough its temporary)
set classpath="C:\Program Files\Apache Software Foundation\Tomcat 6.0\lib\servlet-api.jar"
but the servlet package is still not recognized

Package javax.servlet does not exist - settings appear to be correct
laugh as I write this post...it's hardly a "new topic."...but everything seems set just as it should be...
Okay...I'm a seasoned programmer in every language but JAVA. Here's the issue...every time I try to use the Core Servlets book/website by Marty Hall and Larry Brown I get hung up on the packages. This time, I downloaded and followed step by step what the website said to do...it was even preconfigured for me!

I am suggesting that you need to read the documentation about the product(s) and set them up the way they require, rather than blindly think that the CLASSPATH environment variable is some magical entity.
I will try this, but I was hoping that since my IDE auto configured (with exception to java_home) that I would not have to do this. I wil give it try....thanks for the suggestion.See, you're using an IDE. Like I mentioned, IDEs do not use the CLASSPATH environment variable. You need to set up your project in your IDE in such a way that it knows what the dependent jars are. I'm sure there's a way to add jars to your project's dependencies. -

Having problems compiling *.java with import javax.servlet.jsp......
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.

9 errorsWell, it looks like you've not got the servlet development kit JAR on your classpath. I think it'll probably be called servlet.jar on your system. Add that to the classpath if it's not already there.
Incidentally, you've bumped into one of the areas Java's slightly lenient - declaring a method that looks like a constructor:
public HelloTag() { }
public void HelloTag() { }The first is a constructor, the second is a normal method. I'm assuming you intended to have the former instead of the latter.
Anyway, hope this helps. -

8 errorsWhen compiling servlets etc, you need to include in your classpath a jar file with all the javax.* classes defined in it.
For Tomcat this is called servlet.jar and is in (I think) [TOMCAT_HOME]/shared/lib or /common/lib
For J2EE 1.4 Server, the jar is [J2EE_HOME]/lib/j2ee.jar
Where the _HOME directory is the directory where you installed J2EE.
Include this jar file in your classpath when compiling.
Good luck,

I copy all the .java and .class files to tomcat/webapps/projsp/WEB-INF/classes/ directory. I also write one line in my jsp file as following:
<%@ page language= "java" import="java.sql.*,java.util.*,java.io.*,induction.*" %>
My package named induction. I guess the problem is abput the class path. I don't know how can system find the package of mine. Hopefully, someone can help me!
Below is The error information when I run my jsp:
Internal Servlet Error:
org.apache.jasper.JasperException: Unable to compile Note: sun.tools.javac.Main has been deprecated.
/usr/local/tomcat/work/DEFAULT/projsp/jsp/geography_1.java:9: Package induction not found in import.

Yes! You should create induction subdirectory in classes or
archive induction subdirectory in a jar file and store it in lib
subdirectory.

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 ????.
