COnverting class to jsp
I'm new to jsp and was just wondering how I go about adding my classpath to the jsp page... for example, I have a class like:public class testDriver{
public static void main(String args[]){
MyOtherClass other = new MyOtherClass();
System.out.println(other.ReturnAString());
}Ok. Now MyOtherClass does all sorts of hoobadeedoo, and I need to run my testDriver class with:"java -classpath .\;%AXISPATH%;%XERCESPATH%;%UDDI4JPATH% testDriver"As you can see, I have lots of classes - the AXISPATH, for example, points to 8 .jar files in the axis directory.
My question is, How can I turn the testDriver class into a jsp page? Do I have to copy ALL of the .jar files to my \WEB-INF\lib directory? Am I missing the point here?!
As you can see, Im pretty new to this so any help would be appreciated!
Thanks,
nmoog
Well, copying all the .JAR files works! Im happy!
But is this the best way? do I need to copy them for every project that I use them in?

ACK! Importing classes in JSP?!?! HELP!!!
I am REALLY new to the JSP world and just finished creating a java applet that creates a graph and two combo boxes containing information that I need to display on a web page.
The problem is that I have just been told to convert it to JSP? Is this possible? If it IS possible, how do you import a public class into JSP?
Thanks sooooo much for your help!!!!!
AdamAnswer is yes you can import a java class
Here is how it works
use the following
<%@ page import="com.temp.YourClass*" %>
Assuming that you classpath is set properly
Thanks

Unable to compile class for JSP
Please can anyone help me to solve this.
Actually,this is the condition.
In my db,there is a table called UserPassword, which has 4
fields(empNo,UserName,password,level). Now I want to do these things:
When the user submits the data to create a new account via HTML form, it submits the data to the file called CreateAcc.jsp. In this file it perform some logic,here are they.
1)To check the empNo,if it is already exist in the DB,
if empNo =exist then display error.(record already exist)
if empNo =notexist then do task 2).
2)check the UserName,if it is already exist in the db,
if UserName=exist then display error.(because it's a primary key)
if UserName=notexist then do task 3).
3)Create a new user account and save it to the db.
To do these tasks,I never create a new objects for the tasks 1) and 2).
only for task 3)create an object.
Is it the right way?
Here is the file CreateAcc.jsp
<%@ page language="java" %>
<%@ page import="core.UserAccManager" %>
<%@ page import="data.UserPassword" %>
<jsp:useBean id="UserAccManager" class="core.UserAccManager" scope="session"/>
<jsp:setProperty name="UserAccManager" property="*"/>
<jsp:useBean id="UserPassword" class="data.UserPassword" scope="session"/>
<jsp:setProperty name="UserPassword" property="*"/>
<%
String nextPage ="MainForm.jsp";
if(UserPassword.verifyEmpno()){
if(UserPassword.verifyUsername()){
if(UserPassword.createAcc()) nextPage ="MsgAcc.jsp";
}else{
nextPage="UserNameExist.jsp";
else{
nextPage="UserAccError.jsp";
%>
<jsp:forward page="<%=nextPage%>"/>The directory structure:
UserPassword.java- F:/Project/core/data/UserPassword.java
UserAccManager.java - F:/Project/core/UserAccManager.java
Now both are compiling.I put the class files into the TOMCAT,as follows.
UserAccManager.class - webapps/mySystemName/WEB-INF/classes/core/

Are there any mistakes? If so tell me where is it and how to change them.Please help.I try it that way, but it don't compile.
Error:core\data\UserPassword.java:package javax.servlet does not exist

core\data\UserPassword.java:package javax.servlet.http does not exist

So,I comment them only in the UserPassword.java file,and compile it again.
Then it compile well.I goto the directory to get the .class files.
But there is only UserPassword.class inside the data folder. There is not
UserAccManager.class in the core folder.
Then I try this way,I put my 2 java files in to a new folder,
F:\SystemName\com
When I try it that way, but it don't compile.

So,I comment them only in the UserPassword.java file,and compile it again.
Now both are compiling well.There was 2 class files.
I put them in to the WEB-INF/classes/com directory.
Start the server.But it gave errors:

How to convert .class into .jar file
Hi,
How to convert .class into .jar filejsf_VWP5.5.1 wrote:
Hi,
How to convert .class into .jar fileFrom a command prompt, cd to the location of your .class file(s).
If you want to create a simple jar, use: jar -cf Whatever.jar Whatever.class
If you want to compile all .class files in a directory into a jar, use *.class instead.
Now, I'm going to assume you want to create an executable jar... here's how to do that:
1) Create a blank text file; for this example, lets call it main.txt.
2) In the first line of main.txt, type: Main-class: Whatever ('Whatever' should be the name of the class in your program where the main() method is located)
3) Press enter to go to the next line (someone please correct me if I'm wrong, but if you don't insert the line break/CR after the Main-class: statement, this will not work... in my experience, this is true)
4) Make sure you save this file in the same directory as your .class file(s).
5) Type: jar -cmf Whatever.jar main.txt Whatever.class
...and that's about it. For more information on the usage of the jar command and to understand the switches (such as -cmf), try jar --help.
Hope that helps. -

Unable to compile class for JSP. apache-tomcat-6. What could be wrong?
Hello, I am new to JSP and I am trying a very basic jsp and class file on Windows XP. I get the Unable to compile class for JSP.
Steps that I have done:
javac ch06_01.java , placed the ch06_01.class under
C:\Apps\apache-tomcat-6.0.16\webapps\ch06\WEB-INF\classes
Then grabbed the ch06_02.jsp and placed it under
C:\Apps\apache-tomcat-6.0.16\webapps\ch06\
When I run it (by placing this into Explorer or Firefox URL
http://localhost:8080/ch06/ch06_02.jsp) I get the error further
below. Things I have done and made sure they are in place are:
set up JAVA_HOME to C:\Apps\jdk1.6.0_06
Using CATALINA_BASE: C:\Apps\apache-tomcat-6.0.16
Using CATALINA_HOME: C:\Apps\apache-tomcat-6.0.16
Using CATALINA_TMPDIR: C:\Apps\apache-tomcat-6.0.16\temp
Using JRE_HOME: C:\Apps\jre1.6.0_06
I did a google on the error and I found people saying to place the
tools.jar from the jsk into the lib directory under CATALINA_HOME. But
the examples still don't work. What step could I be missing? Your help is greatly
appreciated.
This is the simple jsp file:
<%@ page import="ch06_01" %>
<HTML>
<HEAD>
<TITLE>Using a JavaBean</TITLE>
</HEAD>
<BODY>
<H1>Using a JavaBean</H1>
<% ch06_01 messager = new ch06_01(); %>
The message is: <%= messager.msg() %>

I just updated the directories of the variables to reflect the current status of my system.What is wrong is that you are using an "old" jsp tutorial :-)
Since Java 1.4, JSPs have been unable to access classes in the "default" package.
What you need to do:
Put the java class ch06_01 in a package.
Steps to do this
- Edit ch06_01 and add the following to the very top of the file (without the quotes): "package mypackage;"
- create a folder "mypackage"
- move ch06_01.java into that folder
- compile that class (now in the mypackage package)
- place ch06_01.class under C:\Apps\apache-tomcat-6.0.16\webapps\ch06\WEB-INF\classes\mypackage
In your jsp:
<%@ page import="mypackage.ch06_01" %>
I would suggest using a more up-to-date tutorial that uses JSTL.
Take a look at this [Apache Tomcat tutorial|http://www.coreservlets.com/Apache-Tomcat-Tutorial/index.html] -

Unable to compile class for JSP--- help me plz!!!!!
hi friends;
Pease suggest me where i am wrong, i think javabean is not instantiated in jsp file.may be it is related to the classpath of javabean. i have not set any variable for javabean classpath. and i put javabean class file in
TOMCAT_HOME/webapps/test3/WEB-INF/UseDta.class
and all the jsp and html in /test3. my jsp an javabeans are--
1. GetName.html

"xml:lang" is getting replaced by "lang" in XML Record converter class
Hi All,
The issue i am having is in the Record converter class which converts XML Record to JCA record, the string "xml:lang" is replaced by only "lang" due to which the transaction i am running fails as the application to which this xml is posted rejects it.
Details:
I have a Custom Resource Adapter(on JCA 1.5 Spec) deployed on Oracle Weblogic Server 10.3. I invoke this adapter from the BPEL process (SOA Suite 11g). I have implemented the XMLRecordConverter interface which converts the XMLRecord to JCARecord. During this conversation the "xml:lang" string is replaced by "lang" due to which the application to which this xml is posted is throwing error.
The code snippet of the XMLRecordConverter implementation is below
import javax.resource.ResourceException;
import javax.resource.cci.Record;
import javax.xml.transform.dom.DOMSource;
import oracle.tip.adapter.api.record.RecordElement;
import oracle.tip.adapter.api.record.XMLRecord;
import oracle.tip.adapter.api.record.XMLRecordConverter;
import oracle.tip.adapter.fw.record.RecordElementImpl;
import oracle.tip.adapter.fw.record.XMLRecordImpl;
import oracle.tip.adapter.fw.util.JCADOMWriter;
import oracle.xml.parser.v2.DOMParser;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
public Record convertFromXMLRecord (XMLRecord xmlRecord) throws ResourceException
String xmlString;
RecordElement payloadRecordElement = xmlRecord.getPayloadRecordElement();
if (payloadRecordElement != null) {
xmlString = serialize(payloadRecordElement);
else {
throw new ResourceException("No data in record from EIS!");
RecordImpl rec = new RecordImpl();
rec.setStr_Payload(xmlString);
return rec;
private String serialize (RecordElement recordElement)
if (recordElement != null) {
org.w3c.dom.Element wsifEnvelopeRootElement =
recordElement.getDataAsDOMElement();
if (wsifEnvelopeRootElement != null) {
JCADOMWriter domSerializer = new JCADOMWriter();
String xmlString = domSerializer.print(wsifEnvelopeRootElement);
return xmlString;
return "<empty>";
the resulting xml has all the occurrence of "xml:lang" replaced with "lang"
If i add namespace ( like xmlns:xml="http://www.w3.org/XML/1998/namespace") at the root element of XML coming from BPEL process then the replacement is not happening.
Has any of the Oracle api's used in the above code uses namespace aware parser or the BPEL engine is replacing "xml:lang" to "lang" when it passes the xml to XMLRecord Converter class?
The above code works perfectly fine in Oracle Fusion 10g (Oracle AS 10 and SOA Suite 10g)
Any information will be really helpful specially in the oracle api's
Thanks,

I had a ton of issues with JBoss and jfreechart. JBoss uses a different classloader, and its internal versions of the jfreechart classes will be loaded before yours, causing all sorts of issues. Dig through the jboss directories and you'll find a different, older version of jfreechart of one of its classes. Remove them and you'll be in better shape.
Alternatively, look around the JBoss docs for how to disable/turn off the unified classloader for your app (its a directive in jboss-web.xml IIRC). This should make the classloader for your webapp perform to spec, getting rid of the class colission issues.
