Re: Absolute file path as dependency in plan

David,

I came up with an idea to use JAR class-path extension mechanism to point eclipse classes from repository JAR file.
First, create a dummy JAR file containing only a MANIFEST.MF with Class-Path entries something like this.

Manifest-Version: 1.0
Class-Path: ../../../../../../../modules/dispatcher/target/eclipse-cla
sses/ ../../../../../../../modules/dispatcher-api/target/eclipse-clas
ses/ ../../../../../../../modules/security/target/eclipse-classes/ ..
/../../../../../../modules/util/target/eclipse-classes/ ../../../../.
./../../modules/app-core/target/eclipse-classes/ ../../../../../../..
/modules/workspace-api/target/eclipse-classes/ ../../../../../../../m
odules/signatures-api/target/eclipse-classes/ ../../../../../../../mo
dules/codebase/target/eclipse-classes/ ../../../../../../../modules/s
ignatures/target/eclipse-classes/ ../../../../../../../modules/snapsh
ot/target/eclipse-classes/ ../../../../../../../modules/locator/targe
t/eclipse-classes/ ../../../../../../../modules/workspace/target/ecli
pse-classes/ ../../../../../../../modules/scanner/target/eclipse-clas
ses/
Created-By: 1.5.0_05 (Apple Computer, Inc.)

Then, deploy the JAR into repository just as same as regular JAR, and point the file as dependency in plan.xml.
I confirmed the code changes made in Eclipse is reflected simply by stop/starting the GBean. No need to bounce Geronimo.
If Geronimo is launched in debug mode from Eclipse, dynamic code replacement may work, I haven't tried though.

The caveat of the approach is the classpath must be relative from the dummy JAR file, but it should be pretty easy to generate the entry automatically as a part of building process.

I hope this trick helps for those who're looking for better integration between Geronimo and Eclipse (or other IDEs).

Thanks,

Kenji

David,

AFAIK, Eclipse output directory must be under the project, so it is impossible to move the destination under geronimo's repository directory unless resorting to symbolic link. I'm reluctant to use such a brute force way since we need to support different dev environment (win32, osx, etc.) Geronimo Eclipse plugin seems to archive and export to repository on code changes, but I believe it is less transparent than the current approach I take.

I'm pretty sure that the geronimo 1.0 repository can only deal with packed jar files in its repository, so if I'm correct even a symbolic link won't work. What you are doing in M5 looks pretty handy :-)

I think that sometime in the future we can support something even more integrated with eclipse by including an additional EclipseRepository that locates artifacts identified by groupId/artifactId/version/type in the eclipse project itself. This will let you use the same dependencies in your geronimo plan in development and production, and let eclipse manage the actual classes. However this is some time off in the future.

Besides, I've read users-ML on Feb. 10 that Aaron Mulder mentioned the default value of 4th path is "jar" when omitted, so I'm wondering if the dependency definition you gave me would be interpreted as "repository/kenjin/util- 1.0.jar" instead of "repository/kenjin/util/1.0" directory. Which is correct?

In a maven 1 style repo, the artifact would be a jar at repository/kenjin/jars/util- 1.0.jar

As mentioned above, I think it has to be an actual jar file, although you could try having a directory there with that name (including the .jar).

I'm afraid that with g 1.0 you will have to jar up your classes and put the jars into the geronimo repo. However, please let us know if I am wrong and you can use an unpacked directory or a link of some kind to the eclipse location.

thanks

I'll try Eclipse plugin if it is impossible to configure GBean to pick up Eclipse's class output directory.

Thanks,

Kenji

Hi,

I'm working on upgrading from M5 to 1.0 release.

For development, I used absolute file URI for dependencies in plans. It worked well in M5, but got the following error when I deploy in 1.0 release.

It was VERY useful with the combination of Eclipse's dynamic code replacement to reduce the frequency of bouncing Geronimo.
Is it no longer supported?? Is there any other way to specify a directory on file system as a dependency instead of jars in respository?

I don't think that it was intentional that this worked in M5 :-)

You need to put your dependencies into the geronimo repository, possibly renaming them so they each have a version, and refer to them using

<dependency>
<groupId>kenjin</groupId>
<artifactId>util</artifactId>
<version>1.0</version>
</dependency>

(Or the all-on -one line format, but I recommend this one -- the other is not going to work in 1.1.)

We're working on another way to support using the classes eclipse knows about, hopefully it will be available shortly after or in 1.1. The new way should let you use the same plan for development and production, so you wouldn't need to change the dependencies.

thanks

The flagment of the plan file looks like this;

<configuration configId="com/foo/bar/Dispatcher" inverseClassloading="false" xmlns=" http://geronimo.apache.org/xml/ns/deployment-1.0">
<import>
    <uri>geronimo/j2ee-security/1.0/car</uri>
</import>

<dependency>
    <uri>file:/Users/kenjin/foo/dev1/engineering/sandbox/kenjin/bar/trunk/modules//dispatcher/target/eclipse-classes/</uri>
</dependency>
<dependency>
    <uri>file:/Users/kenjin/foo/dev1/engineering/sandbox/kenjin/bar/trunk/modules//dispatcher-api/target/eclipse-classes/</uri>
</dependency>
<dependency>
    <uri>file:/Users/kenjin/foo/dev1/engineering/sandbox/kenjin/bar/trunk/modules//security/target/eclipse-classes/</uri>
