Frustrated developer! Any tips/hints for faster development?
I am a relatively new plugin developer, and there are some things that I observe when developing plugins that pushes me beyond frustration.
I am sharing them here, so you can tell if its just me, or if there are others in the same boat! 1. I am not able to rely on the OSGI dialog. If I type ss command once, I get a set of results, and if I type ss again, I get a different set of results. Even if I type ss <bundle>, I get different results (bundle status, bundle numbers) each time, like below. Diag <number> also results in different answers each time. Framework is launched. id State Bundle 346 RESOLVED com.ibm.stst.cpk.common_1.0.0.201205161102 347 INSTALLED com.ibm.stst.cpk.service_1.0.0.201205161102 osgi> ss com.ibm.stst Framework is launched. id State Bundle 340 ACTIVE com.ibm.stst.cpk.common_1.0.0.201205161102 341 ACTIVE com.ibm.stst.cpk.service_1.0.0.201205161102 osgi> ss com.ibm.stst Framework is launched. id State Bundle 346 RESOLVED com.ibm.stst.cpk.common_1.0.0.201205161102 347 INSTALLED com.ibm.stst.cpk.service_1.0.0.201205161102 osgi> ss com.ibm.stst Framework is launched. id State Bundle 340 ACTIVE com.ibm.stst.cpk.common_1.0.0.201205161102 341 ACTIVE com.ibm.stst.cpk.service_1.0.0.201205161102 2. It takes me a loooong time (almost 20-30 mins) to install a new version of a plugin onto Tomcat. I delete the respective folders from under Tomcat/work each time (Is this needed?). I also invoke the jts/ccm url on a browser to speeden it up, and it does make a difference, but it is still very slow. Is there a quicker way to deploy a new plugin? 3. I am not able to rely on the logs generated. For eg: I get errors in the log, but they are not accurate and the bundle (with the "supposed problem") does become "Active" after some time. Example: This is not true, because it does have the com.ibm.team.filesystem.server.rtc.feature included in the feature.xml file, and the plugin works fine. Why are these things happening? Is there anything I can do to avoid it?? Thanks much!!! :) -AJ |

hm.. I don't see these kinds of issues..
is the eclipse and tomcat on the same system? when I create my plugin deployment 'site', I make it point to the directory where the server will actually load the plugin. then I created a small batch file which will force tomcat to rebuild the cache on server startup. here is the batch file
then I shutdown the server, run the batch file, do the build on the plugin site Site.xml, then start the server back up. the longest time is server startup.. about 3 minutes total. I don't ever look at the OSGI console. |

Hello Sam,
I have eclipse and Tomcat on the same system. But I do not share the development folders. I explicitly move the update-site contents to the Tomcat conf/.. folder (just because I feel more reassured that when a client does the same thing, it will work for them as well), and then I delete the work folder and start up Tomcat. I tried deleting the built-on.txt file like how you do, and it did not work, because the server start up complained about not being able to delete the eclipse folders under work/ccm or work/jts... I had to delete the folders - which by itself is not a problem, as long as its a part of the process. And today, I timed the time it takes for it to start-up, and I realize that it takes about 10 minutes on my 64bit newer laptop, but more than twice that on my older 32bit laptop :( Thanks..! |

hm.. my last post didn't get there..
I also copy paste on one plugin cause I created the wrong site project and didn't want to change it.. but not a problem, copy/paste with windows explorer.. I have an Intel I7-2600k @3.40ghz and 16gig of ram.. (windows 7 64bit) I just timed the 3.0.1.1 tomcat server startup from click on the icon to logon to ccm available at 1min 25 seconds.. (having deleted the built-on. txt file in ccm) this server loads three of my custom plugins Sam |
... that 'unable to delete' will happen if a windows explorer window is showing one of the directories in the tree when the delete is attempted.. sam |
