camel xslt an osgi - java.io.FileNotFoundException

[labo32]

Hello,

I try to get a route with a xslt as osgi package up and running.

Environment:

karaf - camel 2.11, camel 2.10

servicemix 4 and 5

route as simple xml file or as jar

blueprint or spring

xsl file in etc directory or as resource in the jar

(the same route bundled as war - deployed in a tomcat works fine)

A lot of combinations - no luck.

Everything ends in

Caused by: javax.xml.transform.TransformerException: java.io.FileNotFoundException: Cannot find resource in classpath for URI: removeNS.xsl

I read about problems with the osgi resource loader but for the freemarker bundle the resource template is found.

Is there a way to get camel xslt and osgi up and running ?

Thanks

Hi,

Append your camel router or even a testcase is more helpful here.

In camel-itest-osgi module, there's a XsltRouteTest, you may wanna check it out.

Hi,

to reproduce the problem download a karaf 2.3.1.

Then install some camel bundles

features:chooseurl camel 2.11-SNAPSHOT

features:install camel-core camel-spring camel-restlet camel-jetty camel-josql camel-jpa camel-xmljson camel-gson camel-xstream camel-stream camel-freemarker camel-script camel-groovy camel-http camel-blueprint camel-jms

add the resource file in etc folder (subdir net/test/resources) and deploy the route

<?xml version="1.0" encoding="UTF-8"?>

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0">

    <bean id="restletComponent" class="org.restlet.Component"/>

    <bean id="camelRestletComponent" class="org.apache.camel.component.restlet.RestletComponent">

        <argument index="0" type="org.restlet.Component" ref="restletComponent"/>

    </bean>

    <camelContext xmlns="http://camel.apache.org/schema/blueprint" id="init-match-context">

        <route id="init-match-route">

            <from uri="restlet:http://localhost:8888/rs/match/{leagueSaison}/{leagueShortcut}?restletMethods=GET"/>

                <to uri="freemarker:net/test/resources/GetMatchdataByLeagueSaison.ftl"/>

                <setHeader headerName="Content-Type">

                    <constant>text/xml; charset=UTF-8</constant>

                </setHeader>

                <to uri="http://www.openligadb.de/Webservices/Sportsdata.asmx"/>

                <to uri="xslt:net/test/resources/removeNS.xsl"/>

                <to uri="xslt:net/test/resources/openliga.xsl"/>

                <split>

                    <xpath>//matches/match</xpath>

                    <to uri="log:match:{body}?level=DEBUG"/>

                </split>

        </route>

    </camelContext>

</blueprint>

The freemarker template seems to be found the xsl file not :-(

Looks like https://issues.apache.org/jira/browse/CAMEL-5223 but this problem should be solved.

Make a bundle with all the resource files did it.

Is this the only way in an osgi camel route to put the resources in a separate bundle ?

Is it not possible to load them from the classpath ?

Note to myself: learn more about osgi

Thanks

Hi,

We suggest put the resource file into bundle, as this way the bundle is self-contained and easy for management.

Though  you can also put the resource file into a folder outside the bundle, provided the folder is on the classpath. This way generally is a little bit tricky as it depend on how your code looks like and which classloader is used.
