Spring Blazeds Integration + OSGI (Virgo) : CGLIB problem

[Vince.vallet]

Hi all,

We've encountered a problem using Spring Blazeds with Virgo Environment.
You can find a summary of config files below.
Thanks a lot for your help.

Can you provide to us, MANIFEST.MF or template.mf (if you using bundlor)?

For your dependencies why you not use:

<dependency>
    <groupId>org.springframework.flex</groupId>
    <artifactId>org.springframework.flex</artifactId>
</dependency>

Hi, Thanks for your reply.
Actually, I had already replaced the dependency:

<dependency>
         <groupId>org.springframework.flex</groupId>
         <artifactId>spring-flex-core</artifactId>
</dependency>

by

<dependency>
         <groupId>org.springframework.flex</groupId>
         <artifactId>org.springframework.flex</artifactId>
 </dependency>

Here are the MANIFEST.MF and template.mf contents:

template.mf

Bundle-ManifestVersion: 2
Bundle-SymbolicName: ui-war
Web-ContextPath: ${web.context.path}
Bundle-Version: ${project.version}
Excluded-Imports: flex.messaging.*

Import-Template: org.springframework.*;version="[3.0, 3.1)"
Import-Package: org.eclipse.virgo.web.dm;version="[2.0.0, 3.0.0)"

MANIFEST.MF

Manifest-Version: 1.0
Bundle-Version: 1.0.0.M2-SNAPSHOT
Tool: Bundlor 1.0.0.RELEASE
Import-Library: org.springframework.spring;version="3.0.5.RELEASE"

 ork.web.context.support;version="[3.0, 3.1)"
Bundle-SymbolicName: ui-war

Thanks again,

Vince

OK, if you use bundlor to create MANIFEST.MF from your template.mf

can you try with:

template.mf

Bundle-ManifestVersion: 2
Bundle-SymbolicName: ui-war
Web-ContextPath: ${web.context.path}
Bundle-Version: ${project.version}
Import-Template: org.springframework.*;version="[3.0, 3.1)"
Import-Package: 
 javax.servlet.jsp.jstl.core;version="[1.1.2,1.2.0)",
 org.eclipse.virgo.web.dm;version="[2.0.0, 3.0.0)"
Import-Bundle: 
 com.springsource.org.apache.taglibs.standard;version="[1.1.2,1.3)",
 org.springframework.flex;version="[1.0.3.RELEASE,1.0.3.RELEASE]",
 com.springsource.flex.messaging.common;version="[3.2.0.3978,3.2.0.3978]",
 com.springsource.flex.messaging;version="[3.2.0.3978,3.2.0.3978]",
 com.springsource.flex.messaging.services.remoting;version="[3.2.0.3978,3.2.0.3978]",
 com.springsource.net.sf.cglib;version="[2.1.3,2.1.3]"
Import-Library: 
 org.springframework.spring;version="[3.0, 3.1)"

I attach one example in this example flex + spring + osgi is successfully integrated jmax.zip
