Greetings

As a former Java programmer who has transitioned into a management role but is interested in getting back into the trenches coding, where would you suggest one to start? The Java landscape is ever evolving and rapidly evolving at that, it is a bit overwhelming in terms of where to start. Should one dust off the old Java hat and rebuild my skill set from core Java or pivot to JavaScript and build my skills up in that area. I really don't have a preference in terms of technology, I'd like to shift back to the technical side.

Thanks in advance.

Greetings! As a long time java developer with an interest in broadening my skills how would you recommend I go about picking up some solid python skills? Is there a particular book or site you would recommend where a seasoned developer wouldn't be board but would be challenged yet gain a solid understanding of the language?

Thanks in advance!

Hello Robin -

Being a long time Java developer I am looking for a change, a new technology to add to my arsenal and I have heard some great things about PHP. How do you see the see the transition form Java to PHP? One would think it would be easier to pick up and master and it could be learned in a short amount of time. What do you vision being the most challenging thing to grasp with PHP coming form Java?

Thanks for taking the time to answer my question!

Hello Bruce -

I have a little knowledge of Ruby and Scala; listening to talks and some self experimentation. I like how Scala removes some of the bloat form the source files and with Ruby I like the seamless use of MVC. I am interested in some of the other functional languages and learning what they have to offer. I am a big proponent of the right tool for the job. I work in a Java shop and at times it is difficult to introduce new technologies or languages to our team and environment. What advice can you give me to introduce some of these languages into my work place?

Thanks in advance!

Not sure how I missed that page, thanks for the link.

I think I have the header set, how can I verify it is set? I tried using request.getAllHeader() to show what is in it but it looks empty.

Thanks for the reply! Since I am new to groovy I found a sample service call to Google and I have been modifying it for what I need. I am actually trying to create this as a portlet for one of our portals; the portlet will allow a user to search our Service Bus and get some results displayed back in the portlet. Any thoughts or guidance in this area would be appreciated as well!

Here is my code so far:

I am new to groovy and I am trying to call a RESTful service. This service requires the setting of remote_user in the header. I am not having much success in getting this set. Has anyone done this before and I would appreciate any guidance or samples.

Thanks in advance!

Hi Jacquie -

I have a question regarding new technologies. I recently attended a symposium and I was introduced to a slew of newer and innovating technologies and languages; they really got me excited. Now my current employer doesn't use any of these technologies and it is really difficult to bring a new technology into the environment. My question is how do I continue to keep my enthusiasm level high concerning the new technologies and learn them the best I can? I don't want to put off learning them but on the other hand I don't have much of an opportunity to learn them and I don't want to keep too narrow of a skill set.

I actually thought of another question; if I aspire to become a software architect do you think it is better to have a specific skill set that you are a rockstar in or is it better to know a variety of different skills?

Thanks!

Thanks Dave I appreciate you answers.

I do have one follow up question. In your opinion do you see groovy or grails as just a fad or something that is here to stay? With my limited knowledge of the languages I think it has really good potential but I of course don't know as much as you do and I was really impressed by the the session I attended at NFJS given by Robert Fischer.

Thanks!

Hello -

I have been hearing a lot about DSL's lately; I recently attended a conference and the DSL's seemed be the hot topic. There were a few sessions on groovy and grails; I was only able to attend 1 session on grails. In that one session I did like what I had seen from grails. Since I am new to the language do you feel it is a good starting point; should I start with grails or would I be better off starting somewhere else and working my way up to grails? I am a pretty experienced Java developer and I am looking for something new. Another topic that was discussed at the symposium was using languages such as groovy and grails to write the test for Java applications; what are your thoughts on this and do you think it would be a good use for grails?

Thanks!

Hello -

I haven been hearing a lot lately about Domain Specific Languages and I have become increasingly curious. I was wondering if anyone could recommend a good one that is not too hard to learn and may be useful in a work setting (we do mostly portlet apps or possible to write our tests in)? I just want to poke around and play with it to see what all the fuss is about. I'd like to start by build some apps for personal use and see where it takes me. Thanks in advance!

We got this workign by doing the following; figured I woudl post it if somepone else comes across it.
The issue was solved by using the PortletSession setAttribute; see the snippet below:

PortletSession ps= request.getPortletSession();
ps.setAttribute("data",data);

Thanks and Good Luck!

Hello -

My team is currently working on a project where we need to export some search results from a jsr portlet into excel. The search results portlet has a Excel Export button and when the user clicks this it does a form post to the server. The server is getting the data we need to export however the data is going through setRenderParameter and it is hitting some sort of size limit thus causing the excel export to fail. Does anyone know a way around this or perhaps another way to accomplish this?

Thanks in advance!
