I spend several hours to do this :
I want to share a javabean between two different webapps .... i want to get
fields and methods of a javabean that is stored in webapp2 from webapps1
I use Tomcat 5.0 and i have read
http://tomcat.apache.org/tomcat-5.0-doc/jndi-resources-howto.html but i get
no success!
Please.. do you have a simple example??.. that is.. code and configurations
(server.xml, web.xml, context.xml...)
follow my codes...
jndiWebShare1 is the folder under tomcat\webapps of webapp1
--------------------------------------------------------------------------
SharedBean1.java .. . under jndiWebShare1\WEB-INF\com\afterbit
---------------------------------------------------------------------------
/*
* SharedBean1.java
*/
package com.afterbit;
/**
*
* @author Admin
*/
public class SharedBean1 {
/** Creates a new instance of SharedBean1 */
public SharedBean1() {
}
private String foo = "Shared Bean 1 : Value of FOO";
private int bar = 0;
public String getFoo() {
return (this.foo);
}
public void setFoo(String foo) {
this.foo = foo;
}
public int getBar() {
return (this.bar);
}
public void setBar(int bar) {
this.bar = bar;
}
}
--------------------------------------------------------------------------
context.xml .. .under jndiWebShare1\META-INF
---------------------------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>

index.jsp.. .JSP page with test bean under jndiWebShare1\
---------------------------------------------------------------------------
<[EMAIL PROTECTED] contentType="text/html"%>
<[EMAIL PROTECTED] pageEncoding="UTF-8"%>
<[EMAIL PROTECTED] import = "javax.naming.*" %>

<body>

<%
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");
SharedBean1 bean = (SharedBean1) envCtx.lookup
("bean/SharedBean1Factory");
out.println("foo = " + bean.getFoo() + ", bar = " + bean.getBar());
%>
</body>
</html>
but I get an exception...
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 17 in the jsp file: /index.jsp
Generated servlet error:
C:\jakarta-tomcat-5.0.27\work\Catalina\localhost\jndiWebShare1\org\apache\js
p\index_jsp.java:69: cannot resolve symbol
symbol : class SharedBean1
location: class org.apache.jsp.index_jsp
SharedBean1 bean = (SharedBean1)
envCtx.lookup("bean/SharedBean1Factory");
Of course if i put in my JSP page
<[EMAIL PROTECTED] import = "com.afterbit.*" %> it works...but.. SharedBean1
should be
a shared resource.. so no need to import com.afterbit..... no?!!
Thanks!
