Unable to compile class for JSP

[shenz]

Dear all.
I've the followinp problem.

I'm using annotation attributes and no ejb-jar.xml

General things: in the ear there is available

META-INF/application.xml
META-INF/MANIFEST.MF
Shop.jar
Shop.war

In Shop.jar all entities and sessions beans are available.

Shop.war contains
META-INF/MANIFEST.MF
and a directory calles web

In this subdirectory "web" the index.jsp file is available as well as the helper classes of objects which are create in the jsp, e.g. the class "Basket"


With JBOSS 4.2.2.GA as well as JBOSS 4.2.3.GA everything worked well, i.e. the deploying as well as the calling of the index.jsp
But with JBOSS 5.1.0.GA after having deployed the EAR file and calling the according jsp, I get error messages like:

org.apache.jasper.JasperException: Unable to compile class for JSP:

An error occurred at line: 74 in the jsp file: /web/index.jsp
Login cannot be resolved to a type
72: wsr = (WebShopRemote)
73: session.getAttribute("WebShopBean");
74: Basket basket = new Basket();
75: basket.getPage(request, out, session, response, wsr);
76: }

...

Does somebody has an idea what might be the problem? Or does somebody has a small EJB example in connnection with a war file and a jsp?

Thx,
Jim

Hi Jim,

does your "Show.war" contain a file META-INF\Manifest.mf with this content?

Manifest-Version: 1.0
Class-Path: Shop.jar

Best regards

Hi Wolfgang,

the Show.war contains a file META/MANIFEST.MF, but has the following content:

Manifest-Version: 1.0
Ant-Version: Apache Ant 1.7.0
Created-By: 11.2-b01 (Sun Microsystems Inc.)

It's the same content for both, working with JBOSS 4.2.2.GA as well as with JBOSS 5.1.0.GA

With JBOSS 4.2.2.GA a can call the index.jsp and Java classes called within this JSP are found and the JSP is compiled, but with JBOSS 5.1.0.GA I get the above mentioned error messages

org.apache.jasper.JasperException: Unable to compile class for JSP:

... cannot resolve to a type ..

Is there a way to get rid of tihis problems. Something important seeemed to be changed from JBOSS 4.2.2.GA to JBOSS 5.1.0.GA

Best wishes,
Jim

Hi Jim,

add the "Class-Path" to manifest.mf, as shown in my previous post:

Manifest-Version: 1.0
Class-Path: Shop.jar

This is required for JBoss to resolve Shop.jar

Hope this helps

Hi Wolfgang

tyes this solves the problem, but because I've the according java classes which are called by the jsp I have to put in the MANIFEST.FM

Class-Path: Shop.war

Thx a lot!

Hi Jim,

this sounds strange. You mean you have to add "Shop.war" to the ClassPath of its own Manifest.mf?

Where do the classes in Shop.war reside? Normally, they should be in "WEB-INF\classes\".

Best regards

Hi Wolfgang,

yes I had to add "Shop.war", because the helper classes which are called from the index.jsp are located unter web/

i.e. the war file contains 2 directories

META-INF/
and
web/

and under web these helper classes are located.

Surely, the war file is packed in an EAR file named

Shop.ear which contains
it's own META-INF subdirectory, namely
META-INF/MANIFEST.MF
and
META-INF/application.xml


and the above mentioned war file Shop.war as well as a jar file Shop.jar where the entities and session beans are packed.

Best wishes,
Jim
WebShop.jar WebShop.war

Hi Jim,

it seems your app is not bundled according to the JavaEE spec.

It should be (taken your sample):

Shop.ear
|---META-INF\application.xml (this file is not required)
|---Shop.jar
 |--META-INF\manifest.mf
 |--META-INF\ejb-jar.xml (optional)
 |--EJB classes and interfaces
|---Shop.war
 |--META-INF\manifest.mf
 |--WEB-INF\web.xml
 |--WEB-INF\lib\yourlibraries.jar
 |--WEB-INF\classes\....
 |--web\some.jsp

The "Shop.war" must not contain any classes which are already contained in "Shop.jar".
Seems the classes in your WAR are in the wrong location.

Hope this helps

H i Wolfgang,

thx. I'll try to adapt the right file and directory structure.

Many thanks for the hints which helped me.

Best,
