Failed to read schema document / blueprint.xsd

[Beeron]

I am trying to get Spring DM 2.0.0 working with Equinox 3.5.1
My spring config file is a minimal one as in the examples:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:osgi="http://www.springframework.org/schema/osgi"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schem...ring-beans.xsd
http://www.springframework.org/schema/osgi http://www.springframework.org/schema/osgi/spring-osgi.xsd">

<bean id="documentUtilities"
class="org.epo.dg3.casap.client.editor.document.im pl.DocumentUtilitiesImpl">
</bean>

</beans>

However when the spring extender starts, I get the error:

"org.xml.sax.SAXParseException: schema_
reference.4: Failed to read schema document 'http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd', because 1) could
not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>."

I don't understand where the reference to "blueprint" is coming from?
Can anyone help?

The full output from equinox is:

Could you double check the META-INF/spring/document-context.xml resource in bundle 12? Make sure that you have the version installed by the framework (which might be an old one due to caching).
Spring DM loads the schema only if required by the configuration file - moreover, this particular schema is already available to Spring DM which makes this error even stranger.
Could you install a minimum number of bundles and then post the list here (using [c o d e] tags please)?

Thanks

Hello,
Since being unable to solve this error I deployed my application in Felix instead of Equinox and it all works fine. However after retrying in Equinox I am still getting the same mysterious error on all my bundles:

It's strange to me that it can work fine in Felix but not Equinox...
Any suggestions much appreciated.

[Costin Leau]

I don't quite understand, document-context.xml is my own...

Right however each platform has its own internal cache and sometimes, the platform keeps reusing an older version and ignored other changes. I don't know how you are starting Equinox but try using the "-clean" parameter (there's an equivalent for it, if you're using the .ini file).

It's strange to me that it can work fine in Felix but not Equinox...

Indeed. Could you please raise an issue on JIRA with a minimal bundle that exposes your problem and some information about your setup, such as the bundles contained in each platform and the versions of Equinox and Felix used along with the stracktrace?
Things are working just fine locally and on the build server and I can't seem to reproduce the problem on my side.

Hallo,

I tried the same like Beeron with Eclipse 3.5.1 and the spring-osgi-2.0.0.M1 release, espacially for an Eclipse RCP application.

I started with the Eclipse Hello RCP Template Project and got the same Errors like Beeron.

Here is the console output:

21265 [SpringOsgiExtenderThread-1] ERROR org.springframework.osgi.extender.internal.dependencies.startup.DependencyWaiterApplicationContextExecutor  - Unable to create application context for [Test2], unsatisfied dependencies: none

So I tried the same without a RCP application but only with a simple plugin project.
All worked fine (i did not change my target platform or something else).

Can anybody reproduce this or has a running example?

I had similar issues with xml schema parsing inside an Equinox environment which also runs Eclipse RCP. I had to set startup levels to 4 for several Spring bundles (e.g. org.springframework.aop) for the XML reader to recognize schema definitions within the bundles.

It still seems it cannot find all schema definitions from within the bundles and it downloads them from the internet (I'm starting to wonder if I should set all start levels to 4 to fix this). When internet is up it now works for me, but Spring starts up very slowly when reading the XML files.

That it connects to the internet for reading schema files was also proven today when I had this error when my internet connection was down:

org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema document 'http://www.springframework.org/schema/beans/spring-beans.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.

[SlowStrider]

Well, I just tried my idea and I set org.springframework.beans and org.springframework.context to auto-start (don't forget this!) with a start level of 4. The start up time of my Eclipse RCP application (which uses Spring to connect to a server) went from 17s to only 6s!!!!!.

For more on these start levels, see Ralf Ebers blog.

I'm not sure if this is the correct way to do this, but I'm sure happy that it works!!!

Note: something like this used to be logged, see how long it used to take to only load the XML files:

Hallo SlowStrider,
thank you for your answer.

I tried your solution but it does not work for me. I have the additional problem, that i'm behind a firewall and i do not know how i can configure the http proxy for my rcp app so that it can load the shema files from web.

Furthermore I do not understand why Spring tries to load the blueprint shema from web at all:
1) I configured my xml files to use only spring namespaces without any OSGi-Blueprint content.
Is this a error in the current release 2.0.0.M1?
2) As i can see in the spring jars (e.g. spring-osgi-core-2.0.0.M1.jar\org\springframework\osgi\blueprint\co nfig), the xsd files are present and so it should only be necessary to load the files from the file system and not from web. If i start the bundle spring-osgi-core before the extender bundle, spring discovers the xsd files, but it seems that the content is not correct.
I get following error message:

Failed to read schema document 'http://www.springframework.org/schema/beans/spring-beans.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>

Any ideas?

Perhaps it is possible to use a cache or provide the shema programatically.
An other question is why it works when i do not deploy a rcp app, but only a plugin. Is it possible, that in this case the eclipse cache and configured proxy settings are used?

Regards
Max

Hi, I forgot to mention that I am also using the 2.0.0.M1 version but that I am using it in combination with the 3.0.0.RELEASE, although I don't know if this matters much.

You are right, Spring-DM should find the xsd files from the bundles and shouldn't download them, but when I do not set the same start level AND auto-start true, somehow it does not automatically find them from the non-started bundles and it tries to download them from the internet.
Just like you, I did not have this problem when I left out all the Eclipse RCP bundles and started my context with no GUI at all.

Have you tried setting auto start and the same start level (4) as the org.springframework.osgi.extender for the following bundles?

• your own bundle
• org.springframework.core
• org.springframework.context
• org.springframework.beans
• org.springframework.aop

I must say I'm not sure if these are all necessary for finding the XSD files, but it seems to work for me.

Maybe someone from Spring can clarify when XSD files can be found and when they can't be found by the osgi extender.

Hallo SlowStrider,

it works, thank you.
Actually i only have to set the bundles

• org.springframework.core
• org.springframework.context
• org.springframework.beans
• org.springframework.aop

to auto-Start.
My own bundles were not necessary.

Even so, i'm not sure if this is the correct solution and it would be nice if someone from Spring can explain the issue.
