Hi there,

I'm trying to get gemini web running on felix and seeing a couple of problems - I'm using gemini-web-incubation-1.1.0.M01.zip.

Firstly I'm wondering if this is something you'd expect to work. Secondly if this "should" work it seems there's some missing bundles from the zip (or I'm missing some configuration step)

Here's the list of bundles I initially tried to install (from the gemini web 1.1.0.M01 zip - top level plus dep jars):

$ ls -1 bundles
com.springsource.javax.activation-1.1.1.jar
com.springsource.javax.annotation-1.0.0.jar
com.springsource.javax.ejb-3.0.0.jar
com.springsource.javax.el-1.0.0.jar
com.springsource.javax.mail-1.4.0.jar
com.springsource.javax.persistence-1.0.0.jar
com.springsource.javax.servlet-2.5.0.jar
com.springsource.javax.servlet.jsp-2.1.0.jar
com.springsource.javax.transaction-1.1.0.jar
com.springsource.javax.xml.bind-2.1.7.jar

com.springsource.org.apache.catalina.springsource-6.0.20.S2- r5956.jar

org.springframework.core-3.0.0.RELEASE.jar
org.springframework.osgi.core-1.2.1.jar
org.springframework.osgi.io-1.2.1.jar

This results in the following exception:

Error starting framework: org.osgi.framework.BundleException: Unresolved constraint in bundle com.springsource.org.apache.catalina.ha.springsource [16]: Unable to resolve 16.0: missing requirement [16.0] package; (&(package=org.apache.catalina)(version>=6.0.20.S2-r5956)(version <=6.0.20.S2-r5956)) - [16.0] package; (&(package=org.apache.catalina)(version>=6.0.20.S2-r5956)(version <=6.0.20.S2-r5956))

at org.apache.felix.framework.BundleImpl.start(BundleImpl.java: 892)
...

The (&(package=org.apache.catalina)(version>=6.0.20.S2-r5956)(version <=6.0.20.S2-r5956)) version range seems a little restrictive...the closest I've found from spring bundle repository are:

com.springsource.org.apache.catalina-6.0.18.jar
and
com.springsource.org.apache.catalina-6.0.24.jar

But these don't export the correct package...

Any clues appreciated.

Regards,

Dave

Hi Dave

That's strange as the missing package is exported by bundle com.springsource.org.apache.catalina.springsource version 6.0.20.S2-r5956 which you seem to have installed.

The 'ha' bundle resolves fine under Equinox. Why don't you try it and then you can play spot the difference? See http://wiki.eclipse.org/Gemini/Web for instructions.

The reason for the specific version range is that Gemini Web uses a modified version of Tomcat 6.0.20. Essentially some changes needed to get embedded Tomcat working in an OSGi environment were accepted by the Tomcat community for Tomcat 7 but not for Tomcat 6, so we had to backport these on to a (private) vendor branch. The code is however present in an Eclipse CQ if you need to get it.

Regards,
Glyn

Hmmm ok understood about the version range issue.

On further analysis the problem seems it could be related to a second level failure due to missing org.apache.coyote packages in the same range.

I see this is provided as a package from the fragment com.springsource.org.apache.coyote.springsource-6.0.20.S2-r5 956.jar...will dig further

Dave

Hi there,

Sorry took me a couple of days to get back to this.

The problem seems to be two fold, firstly the deps folder seems to be missing

com.springsource.org.apache.juli.extras:6.0.24

This is required to satisfy package imports in the following bundles:

com.springsource.org.apache.catalina:6.0.24
org.eclipse.gemini.web.tomcat:1.1.0.M01

If I add this then it works on equinox, but still fails on felix. On felix the problem looks like a resolve failure related to fragments attaching which I'll take up on the felix mailing lists.

Hope that's of interest/help

Regards,

Dave

Embarrassed

Ignore me - com.springsource.org.apache.catalina:6.0.24 was added by my own hacking around...

Just a fragment problem...

I've raised the issue at felix:

http://issues.apache.org/jira/browse/FELIX-2466

Congrats on the release anyway works like a charm Smile

Regards,

Dave
