JSB Beans and Tomcat problem

I'm trying to use a Bean in my JSP page(running on tomcat), but everytime I try to run it says the package doesn't exist, I've placed my package in web-inf/classes/packageName and my class inside of that... The error I get is:

C:\Programmer\Apache Group\Tomcat 4.1\work\Standalone\localhost\_\index_jsp.java:47: package m does not exist
m.Person person = null;
^

Does anyone have any idea what might be wrong? I've been googling for 30 minutes now without luck - and I've tried reinstalling tomcat... my JSP code for calling the bean is:

<jsp:useBean id="person" class="m.Person" scope="session" />
<jsp:setProperty name="person" property="*" />


<Moderator added green checkmark in the first thread>

Looks like you have the beans path for the class attribute wrong in your useBean tag.

Nope it looks like you have it right. I was thrown off by web-inf/classes/packageName

tomcat keeps telling me "The value for the useBean class attribute is invalid."

No matter if the bean is stored in directly within the classes directory itself C:\Jakarta\jakarta-tomcat-5.0.28\webapps\ora\WEB-INF\classes and i use
<jsp:useBean id = "Test" class = "TestBean"/>

or another directory off of the classes dir.
C:\Jakarta\jakarta-tomcat-5.0.28\webapps\ora\WEB-INF\classes\com\MyCompany\Beans
<jsp:useBean id = "Test" class = "com.MyCompany.Beans.TestBean"/>

But what i noticed was that the web container was not compiling my .java file because there was no .class file being generated. It was only when i took the bean out of it's directory and put it into the C:\ dir and compiled it using javac and saw i didnt add in (import java.io*;) and some other stuff then moved it back into the C:\Jakarta\jakarta-tomcat-5.0.28\webapps\ora\WEB-INF\classes\com\MyCompany\Beans
that everything worked fine. :confused:

Didn't we have an extremely similar problem in the past?

I wouldn't know :).

So, you're saying I should try compiling my classes with javac before moving them to the class directory?

In fact, I would move only the .class files to the classes directory.

My current setup is like this:

Code:

---

<appdir>
  -> WEB-INF
    -> src
      -> backend -> at/getdesigned/sciencemapper/*.java
      -> webservice -> at/getdesigned/sciencemapper/ws/*.java
      -> tests ...
    -> classes -> at/getdesigned/.../*.class
    -> build.xml

---

And I simply type
ant
in the WEB-INF directory. The build.xml is written so that it correctly locates and compiles all files to the classes directory.

Ant? I'm not using ant... I mean... I don't even know what ant is, besides the insect... What does it do? And do I have to run it before tomcat's capable of finding my beans ?

http://ant.apache.org/

It's the build tool for all things Java.

In other words, it's a far more comfortable way of compiling everything than calling javac manually.

Okay then :) Thanks!

CornedBee the .xml that you showed where would i find it at? Im looking at a build.xml file generated by NetBeans and it's structure isn't the same.

I wrote it myself.

Here's mine:

Code:

---

<?xml version="1.0" encoding="UTF-8"?>
<project name="ScienceMapper" default="all">
        <description>
                ScienceMapper is a literature organizing system.

        <property name="project.version" value="0.0"/>

        <!-- Apparently 1.5.x doesn't support condition. -->
        <!--
        <condition property="build.optimize">
                <isfalse value="${build.debug}"/>
        </condition>
        -->
        <property name="build.debug" value="true"/>

        <target name="all" depends="webservice,backend,tests">

        <target name="backend" depends="utils">

        </target>

        </target>

        <target name="tests" depends="backend,webservice,utils">

                        source="${build.version}">

                </javac>
        </target>

</project>

Id have to a read an xml book because i don't understand a word of it. :lol:

You'd mainly have to read the Ant documentation.

With JSP, JSF, SQL, then all of the other crap i have to take at uni i think ill just wait. :lol:
