Pax JDBC pooling configuration

[Daniel Las]

Hi,

I'm using PostgreSQL datasource and pax-jdbc-pool-dbcp2. I'm struggling to
find good documentation of datasource pooling configuration. Where can I
find one?

Best regards

Re: Karaf 4.2.10 - NullPointerException during xml parsing

[brock samson]

hi, JB.

thank you for looking at this. The attached zip (rename its extension from .txt 
to .zip) contains both the bundle (rename its extension from .txt to .jar) and 
its feature file. the bundle should be placed in the /bundles dir, and you know 
what to do with the feature file =)
here are some points regarding the bundle:
1) the bundle executes automatically during Karaf startup to make it easier for 
you.
2) The bundle contains both the schema and the xml, so you dont have to really 
do anything to the bundle itself in order for it to just run
3) The bundle contains props.properties where you can specify external 
locations to both schema and xml file if you choose to do so for any reason. 
The provided files will be ignored in such case.
4) I have also provided the source .java alongside the binary just in case.

again, really appreciate you taking the time to look at it. thanks!!!

Brock Samson

Hi Brock,

Maybe you have xerces installed as bundle in your distribution ?

It sounds like a version mismatch.

Can you share the bundles installed ?

Thanks,

Here are the only imports my bundle references in its manifest:
Import-Package:

There are no entries under Bundle-Classpath

Lastly, here is the java code that performs the xml parsing:

RE: Multi-release jar bundles

Hi JB,

Just following up on the issue below. I realize this is really a Felix issue, 
so would it be best for me to submit a Jira to that project?  I realize you’re 
attached to that project as well so I don’t want to submit a Jira if it’s 
already been done at some level.

You can try to wrap settings the TCCL, but it seems more a driver issue.

I have a JDBC driver jar (SAP HANA), that is build both as a bundle and an

1.8, but if I try to use a more recent JDK, the driver throws the following
Caused by: java.lang.AssertionError: Unexpected Java class loaded under Java

An SAP person says they think the classloader isn’t MRJar aware and is loading 
the incorrect class. I most recently tried this with OpenJDK 14.x. Since OSGi 
involves lots of classloader magic, might that be the case or might something 
else be going on here?

Re: Need guide to deploy Spring boot services in Karaf

Hi,

Can you explain your use case a bit more and why you are interesting
about running springboot in Karaf?

Do you have some features you would have in Karaf around springboot?

As JB said, we are currently working on Karaf 5 so every feedback are
very valuable for us :)

Hi,

Spring boot support in Karaf is not yet available out of the box. It will be 
available in Karaf 5 (in preparation).

If you wanna try, you will be able to take a look end of next week.

Hi,

  *   I change to bin-folder
  *   call start.bat (or start.sh)
  *   call client.bat list

The list gets executed, but the command does not snapout. So it waits for

I tried on linux and windows using java 8
