All the guides on using MySQL with Fuse in a project utilizing Blueprint DSL will demonstrate something like this:
1. In your POM declare <Import-Package>com.mysql.jdbc</Import-Package>
2. Install mysql-connector to your OSGi container using "osgi:install"
3. Install your app.
Here's some links: Fuse examples on Git, http://stackoverflow.com/questions/30307288/mysql-connector-in-osgi-environment-gradle-noclassdeffounderror, http://freemanfang.blogspot.sg/2012/03/how-to-use-jdbc-driver-in-osgi.html, http://www.liquid-reality.de/display/liquid/2012/01/13/Apache+Karaf+Tutorial+Part+6+-+Database+Access
If you were getting error "java.lang.ClassNotFoundException: com.mysql.jdbc.Driver not found", you would probably come across the above guides. However, you would be severely misled, because they all do not address the fundamental issue: MySQL changed their package name of the Driver.class.
I guess this is one of the downfalls of proprietary libraries, they change package names at will, and there are 0 OSGi articles that mention this. So the easy fix to your solution would be:
1. Change this in your POM:
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<version>${version.maven-bundle-plugin}</version>
<extensions>true</extensions>
<configuration>
<instructions>
<Bundle-SymbolicName>${project.artifactId}</Bundle-SymbolicName>
<Bundle-Description>${project.description}</Bundle-Description>
<Import-Package>com.mysql.cj.jdbc, com.ibm.mq.jms, com.ibm.mq, com.ibm.mq.constants ,org.springframework.jdbc.*, org.apache.commons.dbcp,*;resolution:=optional</Import-Package>
<DynamicImport-Package>*</DynamicImport-Package>
</instructions>
</configuration>
</plugin>
2. Change this in your blueprint:
<bean class="org.apache.commons.dbcp.BasicDataSource" id="dataSource">
<property name="driverClassName" value="com.mysql.cj.jdbc.Driver"/>
<property name="url" value="jdbc:mysql://localhost:3306/yourdb"/>
<property name="username" value="user"/>
<property name="password" value="pass"/>
</bean>
I really hope this saves some people a heap of time!!
