Problems with extending portlets

2006-03-10T00:45:58Z

it is good sharing the ideas who extended portlet successfully can give some notes. i did some of the prjs on liferay i am happy but only one thing since long time i am unable to solve is i am discussing below. basically i changed liferay code and done the prjs. i dont want to do this anymore. because if i want to migrate to new version really i am changing the code compiling and then i am doing ext environment and replacing jsps . this way working fine.mainly when new vesion comes if i want to migrate its a pain so that why i want to do extn, let me give a hand to finish thius task adding a new extn table and generating ejb's, i hope it is simple who did already thanks for every one who is participating this if we want to add a new table and generating ejb's successfully in extension environment thats a great help for new users. mainly examples for extension environment, if suppose we want add a userextn table which is extn to User_ table then ,how service.xml file,what to add in build.xml in ext-ejb. before that i tried it is giving as Build Successfull but not generating code <img src="@theme_images_path@/emotions/oh_my.gif" style="vertical-align:middle" emoid=":o" border="0" alt="ohmy.gif" /> here what i did my basic requirement is adding more fields to the User Table. prev i changed liferay code. i dont want to do in future. so i stared to created my own table User_Ext which have the fields are userId,Region,col1,col2. then i gone to ext/ext-ejb/service.xml it is like this for reports <?xml version="1.0"?> <!DOCTYPE service-builder PUBLIC "-//Liferay//DTD Service Builder 3.6.1//EN" "http://www.liferay.com/dtd/liferay-service-builder_3_6_1.dtd"> <service-builder root-dir=".." package-dir="com.ext.portlet"> <portlet name="Reports" short-name="Reports" />

</service-builder> if i want to generate ejbs for my table, where i have to mention? my table is basically extension of user table my build-parent.xml in ext-ejb <?xml version="1.0"?> <project

Problems with extending portlets

Yes, I got the source of 3.6.1 and then i downloaded the bundled jboss-tomcat enterprise edition. I followed the directions on how to extend the environment and everything works fine until I run deploy from ext-ejb and ext-web.

I get the same problem with jboss-jetty, but only with the ext-ejb. If I do the ext-web it updates the pages and all is deployed ok. (see my "Deply Error" post) Can anyone help?

Hi, I want to make some changes to the calendar portlet. So I built the ext environment and when i deploy the ext-ear everything works great. However, when I run deploy from ext-ejb and ext-web the deployments complete successfully, but when i start jboss-tomcat I get a lot of NoClassDefFound errors, as if the jndi can't link the appropriate ejb's. I am using Liferay 3.6.1 on WinXP Jboss-Tomcat, MySQL 5.0 Can any one please help me. Thank you in advance. Peter
