Reflections with JBoss 7.1.0.Beta1 #93

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
Hello,

I'm trying to test reflections with my test ear (containing ejb) project, 
deployed in JBoss 7.1.0.Beta1. First I tried to scan classes in runtime, but to 
no avail. Then I tried the reflection-maven plugin, and it created the 
rest1-ear-1.0.0.ear\rest1-ejb-1.0.0.jar\META-INF\reflections\rest1-ejb-reflectio
ns.xml file.

First problem I ran into was vfs, since JBoss 7 apparently uses vsf prefix, but 
0.9.5 version of reflection uses vsffile prefix. I exported the latest trunk 
version from the svn (0.9.7-SNAPSHOT) and built it, because this noticed this 
was fixed. But now I have a new problem: the ClasspathHelper.java file, method 
forPackage in line 56:

int index = url.toExternalForm().lastIndexOf(encodedResourceName);

url.toExternalForm() does not encode the path (backslashes remain \ ), but 
encodedResourceName is "META-INF%2freflections", so the comparison fails 
always. I changed the line to

int index = url.toExternalForm().lastIndexOf(resourceName);

and now index is > 0, but then the following exception is thrown:

Maybe the problem is in the vfs path. I hard deploy ear into 
c:\java\jboss-as-7.1.0.Beta1\standalone\deployments\ folder, but the vfs path 
reads as C:\java\jboss-as-7.1.0.Beta1\bin\content

Are my problems just the fact that reflections are not compatible with JBoss 7 
or am I doing something wrong?

Hi,

i'm facing the same problem and therefore i decided to create a patch. 
Unfortunately release versions are not tagged in svn, so i started from svn 
revision r141 which seems to be the last revision for latest stable version 
0.9.6. This is a quick and dirty solution as it depends on jboss-vfs.jar, but 
it works for me.

Hi, with 0.9.7 - RC1 it works on jetty it fails on Tomcat 7

Reflections ref = new Reflections(new ConfigurationBuilder()
        .setUrls(ClasspathHelper.forWebInfClasses(sc)));
Set<Class<? extends RemoteService>> classes = 
ref.getSubTypesOf(RemoteService.class);

Error:

rsallar: it does not fail, it just says it could not handle jndi: protocol. 
implement that vfs type or ignore. you probably don't really want to scan that 
jar.

I don't get how forWebInfClasses return urls from web-inf/lib...

Hi ronm,

today i stumbled upon this issue again. Sorry that i did not answered your 
post, i've missed it somehow. However i did some research and found that the 
0.9.7 release supports vfs_jboss7 as where latest release 0.9.8 seems not. Is 
this correct and if so why this was removed with latest release?
