[JBoss OSGi Development] - Re: Cannot resolve circular dependencies

by thomas.diesler＠jboss.com

I isolated the issue sufficiently to this problem BundleC exports A, B imports A BundleD exports A, imports A, B Both bundles will only resolve if one uses a self dependency. I modified the code such that the Domain warns if a requirement resolves against multiple modules | Module firstMatch = null; | for (Module other : modules) | { | List<Capability> capabilities = other.getCapabilities(); | if (capabilities != null) | { | for (Capability capability : capabilities) | { | if (capability.resolves(other, module, requirement)) | { | if (firstMatch != null) | { | String otherName = other.getName() + ":" + other.getVersion(); | String firstName = firstMatch.getName() + ":" + firstMatch.getVersion(); | log.warn("Requirement " + requirement + " resolves agaist " + firstName + " and " + otherName + " - using first."); | } | if (firstMatch == null) | firstMatch = other; | } | } | } | } | and | I extended the interface like this | | public interface Capability extends Serializable | { | /** | * Whether this capability resolves the requirement | * | * @param capModule the capability module | * @param reqModule the requirement module | * @param requirement the requirement | * @throws IllegalArgumentException for a null requirement | * @return true when it is resolves the requirement | */ | boolean resolves(Module capModule, Module reqModule, Requirement requirement); | } | | which allows capability/requirement matching in the context of both modules. | | | | public interface Capability extends Serializable | | { | | /** | | * Whether this capability resolves the requirement | | * | | * @param capModule the capability module | | * @param reqModule the requirement module | | * @param requirement the requirement | | * @throws IllegalArgumentException for a null requirement | | * @return true when it is resolves the requirement | | */ | | boolean resolves(Module capModule, Module reqModule, Requirement requirement); | | } | | | | View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4254146#4254146 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4254146

[JBoss AOP Development] - Re: Help needed to create a patch.

by ZeroTolerance

I found out what the problem was. I had my JBOSS_HOME environment variable point to a real JBoss installation instead of the one that was going to be tested. After fixing that I did a rebuild of the JBoss environment and the testsuite and did the tests again. This time the tests did not give me any errors or failures. I did see some exceptions going by in the JBoss console. Some of the exceptions were: Missing dependency, IllegalState, NoSuchEntity and InvalidSelector The tests came out OK so I guess I'm done testing? I do need to create a diff now if I'm correct. So my next question would be of what?

wrong forum... and please search the jira.... seems to be a 'known' issue Oh, and why do you not turn it into a real unit test View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4254053#4254053 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4254053

[jBPM Development] - Re: Integrating an application with the jBPM, I need to use

by kukeltje

Well, it is not scheduled and there are not many votes for it, not have there been many requests in the forums, so the chance of it being included in 4.2 is virtually zero. But in the jira, there is a kind of patch provided that might do what you want, so give that a try.

[jBPM Development] - Re: Creating domain specific nodes into a jbpm-editor

by koen.aers＠jboss.com

Jan, Something I forgot to ask: what is your timeline for this? - When is it supposed to be finished? - When do you start? - Are you working on it constantly or maybe one day a week? I would need this information to be able to include this in our overall planning. Cheers, Koen View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4254038#4254038 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4254038

[jBPM Development] - Re: Creating domain specific nodes into a jbpm-editor

by koen.aers＠jboss.com

Jan, Do you have any experience with Eclipse plugin development? If not it would be good to read a tutorial about it (http://www.vogella.de/articles/EclipsePlugIn/article.html is a good start). We will need to define (or streamline) a few more extension points to enable smooth pluggability, so make sure you also read on how to define these. There are some good examples in the GPD code base already. Which brings me to the topic of checking out the GPD code base so you can work on it: - the SVN plugins as well as the GEF framework and the XML editor have to be installed in your eclipse installation to be able to check out the code and compile the code correctly. - add the jboss tools svn repository to your workspace - check out the following projects: * org.jboss.tools.flow.common * org.jboss.tools.jbpm.common * org.jboss.tools.flow.jpdl4 * org.jboss.tools.flow.jpdl4.multipage Let me know if this worked fine and you're able to browse the code. Cheers, Koen P.S. I am usually to be found in the #jbpm irc channel on irc.codehaus.org. Ping me there for immediate help with this if needed.
