Infinispan listener event owner

It took me a while to find this, it exists from version 5.3 of infinispan.

I have a cluster and i want that only the instance which got that event and insert it into the cache will handle - in my case, save it to the db. Other replicated instances caches listeners won't work because in this particular event they aren't the owners .

You just need to annotate this above your listener : @Listener(primaryOnly = true)

org.hsqldb.HsqlException: data exception: string data, right truncation; table

Hi,

I had this exception while testing (junit) my code.

It seems that when you use +Hibernate.org  Lob annotation and use HsqlDB, the default column size is probably less than the actual size you are trying to insert. In my case i annotated String with Lob (hibernate knows it should be clob) while my string length was huge -> got this exception.

To fix this, add hibernate column annotation with column length bigger like 15000 , this will solve it  (for example of course).


Hoped it helped,

fedora 19 alacarte doesn't add icons to new applications

After wondering for a while,

I have found that you need to go to ~/.local/share/applications
edit each alacarte desktop file and fill manually the icon location and extension. 
Worked for me.

dpkg: error: parsing file '/var/lib/dpkg/status' near line 9941 package 'libcloog-isl4:amd64'

After wasting let's say one hour, this solved it for me :
'sudo mv /var/lib/dpkg/status-old /var/lib/dpkg/status'

Set up gradle to build with alternative java

I am using ubuntu 14.04 LTS

Having java 7 and 8 installed from oracle.

Using alternative and working with java 7 but one of my projects use java 8.

gradle build --version

returns that it works with java 7 -> since most of my projects use this version, i don't want to change this.

Solution: creating in the java 8 project, in the root directory, file named gradle.properties

inside it for example in my case :
org.gradle.java.home=/usr/lib/jvm/java-8-oracle/


this way, when you will do gradle build in this project, gradle will use this version instead of the one defined for him.
