Last Saturday(19th April) i appeared for core Spring V3.2 certification exam and cleared with 88%.

Here is the material that i used:

1. http://www.selikoff.net/2010/08/20/jeannes-core-spring-3-certification-experiences/: Jeanne has provided excellent notes for the certification. These were my starting point.
2. http://arnosthavelka.github.io/spring-cert/index.html#! :These are also very good notes.
3. http://itestjava.com/java-certification-practice-tests/product/enter.do?product=SPRING-CORE: Purchased mock exam from itest. Some questions in these tests were out of scope. But, it gave a good learning practice for the certification.
4. Skill Guru: Purchased mock exam from here and still few questions were out of scope but still it gave a good idea of the questions.
I attended that in india so it was 53K rupess. I gave 50K just as a round figure.

I attended the Spring Certification training in December but i have still not received the exam voucher. I called VMWare team multiple times and sent them multiple emails(created atleast 7-8 tickets) but they are saying that your class is not closed and then they are saying we are short of exam vouchers.
Now, finally they are saying, we will give you exam voucher whenever it is available with us without giving me any date by which i will expect the voucher.
I haven't encountered such kind of issue with other Sun, Oracle, PMP certifications.
It is really irritating that they take 50K and then they say just keep on waiting for the voucher.
Probably i will not go for any other Spring certification exam after this.
But as i already paid 50K i need to appear for this. Can somebody tell me what should i do to get the Spring Voucher?

I saw on net that books for OCMJEA 7 are available in market but looking at this forum and other ocmjea forums, i found that most of the people are still doing OCMJEA 5 or OCMJEA 6. Can somebody please suggest if i should prepare for OCMJEA 7. If yes, can somebody please tell the preferred books for OCMJEA 7.

Below is the link for OCMJEA book:

I have written code using spring quartz scheduler and it is working fine. But, in that i have specified value of cron expression in applicationcontext.xml. So, i now need to read the value of CronExpression from properties file so that if we need to change the time of execution, we can just change properties file and restart the server.
<bean id="CronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail" ref="CronJob" />
<property name="cronExpression" value="0 0 3 * * ?" />

I can't do
<bean id="CronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail" ref="CronJob" />
<property name="cronExpression" value="{cronExpression}" />
because i don't have control over CronTriggerBean as it provided by Spring.

So, can anyone please tell how we can read the value of cronExpression from properties file.

Ok, i am now planning to create UML diagrams myself. I believe we can install some pluggins in eclipse after which we can create UML diagrams through eclipse.

Please let me know the pluggin which i can use for making UML diagrams in eclipse.

I have written some piece of code in eclipse. Now, i need to generate UML diagrams for that code. Please let me if it is possible in eclipse to just select particular project/package and generate sequence diagrams/class diagrams as per the classes present in that project/package.

I am looking for an open source pluggin. I know we have EMF and UML2 pluggins for eclipse but i think even if we have those pluggins, we still have to understand relationship between the classes and connect the classes accordingly in UML diagrams.

Just wanted to know if any open source pluggin is available which will reduce my effort and will generate UML diagrams by just selecting a project/package.

Thanks in advance.
Ok thanks. I am planning to implement Merge functionality myself.
Hi all,
