AS6.4 SP8: JSP-Engine Error when using jsp:usebean with beanName='<%=xx%>'

[Former Member]

Hi,

we are using SAP AS 6.4 SP8.

The JSP Engine seems not to be able to compile the following statement implemented in one of our JSPs:

<jsp:useBean id='ObjectsBeanVar' scope='page'

beanName='<%= sClassname %>'

type='com.viaMEDICI.custom.viaCONTENT.Objectable'>

The JSP Engine tries to find a Bean with the name "<%= sClassname %>" instead of using the Variable which is pointing to a class "com.viaMEDICI.custom.viaCONTENT.ImagesBean".

thanks

Michael

Hi Michael,

could you please give me the "sClassname" declaration code?

Hi Bojidar,

sClassname is declared like this:

<% String sClassname =

"com.viaMEDICI.custom.viaCONTENT.dynamicdata."+sType +"Bean"; %>

But the problem seems to be, that the JSP-Engine doesn't try to use the sClassname as a Variable.

The JSP-Engine uses "...sClassname..." as classname

during compilation.

And here's the runtime error:

500 Internal Server Error

SAP J2EE Engine/6.40

Application error occurs during processing the request.

Details: java.lang.InstantiationException: ID018236: Cannot instantiate bean. java.lang.ClassNotFoundException: <%= sClassname %>
