Tycho build with RAP 2.1 [message #1066963]

Eclipse User

Hello everyone,

I try to build my RAP application with tycho and I get an error:
"Missing Constraint: Import-Package: javax.servlet;"

I have a target platform definition which uses local software site (update site) to fetch bundles. javax.servlet (3.0.0) is in the target platform. I use your example from here: https://github.com/eclipsesource/tabris-demos to configure poms. If I build my projects with maven I get get following errors:

NOT RESOLVED org.eclipse.rap.ui_2.1.0.20130604-1251 : C:\Users\d.huber\.m2\repository\p2\osgi\bundle\org.eclipse.rap.ui\2.1.0.20130604-1251\org.eclipse.rap.ui-2.1.0.20130604-1251.jar
Missing Constraint: Import-Package: javax.servlet.http; version="2.3.0"

[ERROR] Internal error: java.lang.RuntimeException: org.osgi.framework.BundleException: Bundle MyProject cannot be resolved
[ERROR] Resolution errors:
[ERROR] Bundle MyProject- Missing Constraint: Import-Package: javax.servlet; version="0.0.0"
[ERROR] Bundle MyProject- Missing Constraint: Import-Package: javax.servlet.http; version="0.0.0"

Have you any idea what it can be? I build with RAP 2.1.0 and maven 3.0.5 an tycho 0.17

Best regards,
Daria

Hi Daria,

I don't know the reason of your problem but usually it is connected with the org.eclipse.equinox.servletbridge.extensionbundle bundle - see bug 348045 [1] for further information about changes in Kepler in that area.

Speaking of changes... your tabris example that you mentioned seems a bit old. I'm not aware of any particular problems with this build, but on the other hand I cannot guarantee that it is still working. Maybe it helps to look closer into our build of the RAP examples. They are in our RAP Runtime Git repository [2] in the releng/org.eclipse.rap.examples.build subdirectory [3].

Hi Markus,

thanks for your reply.
Tycho build for RAP 2.1 is a bit differently to RAP 2.0. So I changed my build just like in your example from releng.
But it doesn't work.
I get:
Failed to execute goal org.eclipse.tycho:tycho-compiler-plugin:0.18.0:compile (default-compile) on project MyProject: Compilation failure: Compilation failure:
Access restriction: The type ServletException is not accessible due to restriction on classpath entry...

My application bundles has project.build/parent/pom.xml as parent pom. And only feature and product has a top parent as parent pom. Also I added my bundles to project.build/pom.xml as modules.

Is it still a bug like 348045 or my problem is between keypad and a chair? Smile

Thanks in advance

Obviously there's still something wrong but the error message doesn't tell me the real reason. "ServletException is not accessible due to restriction on classpath entry...". I'm puzzled.

E.g. in our workbench example, we are using javax.servlet_3.0.0.v201112011016.jar and org.eclipse.rap.ui_2.1.0.20130604-1251.jar in our .war file and the build (and the application) run successfully.

How can we proceed? If MyProject is just one example standalone project and does not include any secret information nor code it may help to attach this project to this newsgroup thread.

Hi Markus,

I figured out what the problem is. Thanks for your help.
Version in MANIFEST for javax.servlet caused this curious exception. I deleted all versions in Manifest under dependecies and I could build war archive for my application. But I think it is not a proper way. I think I have to specify what versions of bundles I want to build with.
I tried to deploy my war archive on a tomcat. But it fails. Bundle org.eclipse.persistence.jpa.osgi is missing some dependecies:

org.eclipse.persistence.jpa.osgi
osgi> diag 69
reference:file:plugins/org.eclipse.persistence.jpa.osgi_2.4.1.v20121003-ad44345.jar [268]
Direct constraints which are unresolved:
Missing imported package javax.persistence_[1.1.0,2.2.0).
Missing imported package javax.persistence.criteria_[1.1.0,2.2.0).
Missing imported package javax.persistence.metamodel_[1.1.0,2.2.0).
Missing imported package javax.persistence.spi_[1.1.0,2.2.0).

I found this https://bugs.eclipse.org/bugs/show_bug.cgi?format=multiple&id=407730. Is my target platform not complete? But javax.persistence is contained and I see it under osgi console.
What is a proper way to manage my target platform bundles?

Maven Central repository
Target definition with links to p2 repositories
Nexus

I would like to have our target platform in our local company network. But solution with a target definition file with p2 repositories is not very reliable. Some bundles like axis2 or eclipelink 2.4.1 are not available with p2. What is the best way to share the same target platform configuration between Tycho and Eclipse?

Thanks in advance

Hi Daria,

great, it seems to work! Maybe part of the problem is the different versioning between OSGi bundle and Java packages in javax.servlet. The bundle has version 3.0.0, whereas the Java packages are exported as 2.6.0.

Then... I see you are familiar with the OSGi console and how to use it on a server. It's the same way of debugging that I would do: Find out which missing dependencies are causing the errors in the dependency chain. It's very likely another bundle that is missing or another incarnation of bug 407730.

Managing target bundles? There are at least as many ways to do this as there are different requirements. I'm usually using the upstream p2 repositories at eclipse.org if possible. If that's not possible (which is sometimes the case behind company firewalls), I am mirroring these p2 repositories to a local location, or I am using a Nexus server as a "p2 proxy". In all cases, I'm adding the remote p2 repositories as a repository with p2 layout to my pom's.

Maven Central is in most cases not suitable. Why? Because most Eclipse projects do not publish their artifacts there.

Sorry, but I have still a problem with javax.servlet. I tried to build a very simple project with your example from releng. But my war doesn't work. Here is osgi console:

I do not understand what is wrong. My war is deployed on Tomcat 6.0. And I would say tomcat has servlet-api.jar with correct version. Have I forgot any bundle?

Hallo everyone,

I have still problem to run WAR on tomcat. I attached my projects. Maybe it helps to figure out what is the problem.
My p2 repository <rap-repository> is only a mirror of RAP p2 repository and <others-repository> contains only "simpleconfigurator" bundle.

I have no idea what is wrong. I would be grateful if anyone can help me. All poms are configurated like Markus's example under releng.

Thanks in advance,
Daria

Hallo everyone,

I suppose the whole RAP team is on holiday. But if somebody is there and can help me I will be very glad!

I tried a very basic maven build with demos from git. Steps to reproduce:

1. Clone git repository: http://git.eclipse.org/gitroot/rap/incubator/org.eclipse.rap.incubator.releng.git and import projects.
2. go to .../org.eclipse.rap/releng/org.eclipse.rap.examples.build/ and execute "maven clean install"
3. copy worbenchdemo from /org.eclipse.rap/releng/org.eclipse.rap.examples.build/workbenchdemo/product/target to Tomcat 6.0 webbapps directory
4. turn osgi console in web.xml on
5. start tomcat
6. Exception!!!

Hi Daria,
which exact Tomcat version are you using? I've tested our demos with
latest 6 ( 6.0.37 ) and 7 ( 7.0.42 ) versions on Windows and it's
working fine. I observed the same problem like you with Tomcat 5.5.35
(exported demos with WAR Product against RAP master). Could you try
Tomcat 6.0.37 or 7.0.42?
Best,
Ivan

Hallo Ivan,

I have Tomcat 6.0.35. My colleague have the same version and gets also "missing javax.servlet" exception. Under Tomcat 7.0.39 is the same behaviour.

It's very strange.

Hi Daria,
I've run the maven build locally in
org.eclipse.rap.examples.buildproject and I can reproduce the same
problem as you. I found that in the config.ini (located in
"apache-tomcat-7.0.39\work\Catalina\localhost\workbenchdemo\eclipse\configuration")
the "osgi.framework.extensions=" is empty. For now the reason is unknown
for me (I'll check it with Markus tomorrow). Please change the
config.ini as follows:
----------------
#This configuration file was written by:
org.eclipse.equinox.internal.frameworkadmin.equinox.EquinoxFwConfigFileParser
#Tue Jul 23 15:20:46 EEST 2013
osgi.bundles=reference\:file\:org.eclipse.equinox.simpleconfigurator_1.0.400.v20130327-2119.jar@1\:start
equinox.use.ds=true
osgi.bundles.defaultStartLevel=4
osgi.framework=file\:plugins/org.eclipse.osgi_3.9.0.v20130529-1710.jar
/osgi.framework.extensions=reference\:file\:org.eclipse.equinox.servletbridge.extensionbundle_1.3.0.jar/
eclipse.p2.data.area=@config.dir/../p2
org.eclipse.equinox.simpleconfigurator.configUrl=file\:org.eclipse.equinox.simpleconfigurator/bundles.info
eclipse.p2.profile=DefaultProfile
-----------------
After adding the
"org.eclipse.equinox.servletbridge.extensionbundle_1.3.0.jar" to
"osgi.framework.extensions" everything is working fine for me.
HTH,
Ivan

Hallo Ivan,

it works!
We tried to start workbenchdemo with your changes on "apache-tomcat-7.0.39\work\Catalina\localhost\workbenchdemo\eclipse\configuration\config.ini", but it didn't work.

So we changed config.ini in workbenchdemo.war:

#This configuration file was written by:
#org.eclipse.equinox.internal.frameworkadmin.equinox.EquinoxFwConfigFileParser
#Tue Jul 23 15:20:46 EEST 2013
osgi.bundles=reference\:file\:org.eclipse.equinox.simpleconfigurator_1.0.400.v20130327-2119.jar@1\:start
equinox.use.ds=true
osgi.bundles.defaultStartLevel=4
osgi.framework=file\:plugins/org.eclipse.osgi_3.9.0.v20130529-1710.jar
osgi.framework.extensions=reference\:file\:org.eclipse.equinox.servletbridge.extensionbundle_1.3.0.jar/
eclipse.p2.data.area=@config.dir/../p2
org.eclipse.equinox.simpleconfigurator.configUrl=file\:org.eclipse.equinox.simpleconfigurator/bundles.info
eclipse.p2.profile=DefaultProfile

and deployed again. And now it works in Tomcat 6.0 too!

Is config.ini generated by simpleconfigurator bundle? It would be nice if war file would work out of the box.

Thanks a lot
Daria

Hallo everybody,

I tried to find automatic way to generate proper config.ini. So I added some lines to product pom.xml to replace "osgi.framework.extensions=" by "osgi.framework.extensions=reference\:file\:org.eclipse.equinox.servletbridge.extensionbundle_1.3.0.jar/"

My pom.xml under /workbenchdemo/product looks like...
....
<plugin>
<groupId>com.google.code.maven-replacer-plugin</groupId>
<artifactId>maven-replacer-plugin</artifactId>
<version>${replacer-version}</version>

....

It's only a workaround but I think it's ok....

UPDATE: In our master branch of our RAP Runtime Git repository [1] I made some changes to the Examples build. Thiese changes will go into RAP 2.2 (RC1).

One of the changes removes the simpleconfigurator, the other changes updates the config.ini with the required extensionbundle. With these changes the created .war files are working out of the box in my local Tomcat.
