Jar file import problem with ADF application

Question

Hi Everyone,
I am using Jdev 11g with integrated WLS. I have an ADF application and is trying to integrate JasperReport in it. I added the JasperReport JAR file in the project properties -> Libraries and Classpath, and checked it for "export" and "Deployed by Default'. I have my JasperReport codes in my managed bean
as follows
+public String cb1_action() {+
+try {+
+JasperDesign design = JRXmlLoader.load("C:/JDeveloper/mywork/ReentryApplication/ViewController/public_html/jasper/testReport.jrxml");+
+JasperReport report = JasperCompileManager.compileReport(design);+
+....+
+}+
+}+
I am able to compile the managed bean class successfully. However when I run the application, I got a stack of errors like this,
+[2009-10-08T11:31:59.910-04:00] [DefaultServer] [ERROR] [] [javax.enterprise.resource.webcontainer.jsf.application] [tid: [ACTIVE].ExecuteThread: '4' for queue: 'weblogic.kernel.Default (self-tuning)'] [userId: test123] [ecid: 0000IGollZuB5EirL4YBUA1AnVop00000L,0] [APP: ReentryApplication] java.lang.RuntimeException: net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file:[[+

+import net.sf.jasperreports.engine.*;+
+....+
It appears that the JAR file is not picked up at the runtime correctly. I tried a simple Main class with the same codes and JAR file added, it works fine. Does anyone know what I am missing within the ADF application?
Any helps would be appreciated.
Thanks,
John

Answer 1

Timo,
Thanks you for your prompt response.
1. I checked The following folder (I assume this is where it supposes to be). The JAR file is there.
C:\Documents and Settings\MISSP29\Application Data\JDeveloper\system11.1.1.1.33.54.07\o.j2ee\drs\ReentryApplication\ReentryApplication-ViewController-webapp\WEB-INF\lib
2. I did not do anything about deployment descriptor. Since I run my application within JDev integrated WLS, I did not do anything about deployment setting. Do I need do something with deployment descriptor if I want to import additional JAR files here? With my experience with 10g, to add a JAR file within JDev, all I need to do is to add it through project properties ->libraries.
3. I agree with your absolute path comment. This is a test of how JasperReport works with ADF application. I will work it out later.
Thanks,
-John
