java bean location
while using jsp:usebean where should i place my bean class?
shld i put into classes folder?or make a package first.
i have hello.jsp with following code
<jsp:useBean id="t1" class="pkg.Mybean"/>
<jsp:setProperty name="t1" property="name" value="ducat"/>
<%=t1.getName()%>
and i get error on executing:
/hello.jsp(1): class 'pkg.Mybean' could not be loaded
probably occurred due to an error in /hello.jsp line 1:
<jsp:useBean id="t1" class="pkg.Mybean"/>
Either or should work. Just remember that if you use a package name in your UseBean value, then your actual bean must also declare itself as being from that package and your jar file or classes dir must contain a directory or parent entry for each package noted. e.g: org.myco.myapp.beans.MyBean would have to either have jar entry of:
org/myco/myapp/beans/MyBean.class OR classes location of:
org/myco/myapp/beans/MyBean.class
If you use a jar, then plop the jar into your WEB-INF/lib.
If you choose not to use a package (which is discouraged), then you simply put your class in the root of your WEB-INF/classes directory e.g.: WEB-INF/classes/MyBean.class
But your bean cannot declare itself belonging to a package or else the appserver will go looking for it in the wrong spot.

Not only is it discouraged, it simply wouldnt work too. All classes have to be packaged if you are using tomcat 5.0 and above.
ram.
