Thanks for the feedback...we are trying to make the installation/setup process for our Linux plug-in much less painful with each release

. We made some strides in 3.3.0 by ridding ourselves of 3rd party installers and environment variable dependencies, and we will continue to make progress in this area.
Here are some comments...for you and others...
If you have 64-bit Eclipse you need to download and install 32-bit Eclipse and 32-bit JRE for use with SECore.
This should have been added to the release notes (requirements)...but it wasn't.
SECore requires Java Development Kit (JDK) for execution. So, before installing SECore you need to install it if not already installed:
Help->Software Updates->Find and install...->select 'Search for new features to install'->Next->select 'Europa Discovery site'->Finish. In Search Results: open 'Europa Discovery site', open 'Java Development' and select 'Eclipse Java Development Tools'->Next->accept terms->Next->Finish.
The directions are correct, but he means JDT. This is listed in the requirements.
If you use desktop application launcher make sure you configure it to Type = 'Application in Terminal' (or Terminal=true). Otherwise Eclipse crashes.
This one is an artifact of the new licensing approach used for Core (believe it or not), we had the same problem with SlickEdit under Linux for SlickEdit 2008. I believe this will be fixed for Core 3.4.
Default configuration of Eclipse is not good enough for large projects: Eclipse will crash during tagging. This can be solves by giving Eclipse more memory
Increasing the JVM heap size for your large project...this is good to know. Hopefully this will alleviate some headache for a future customer/trialer. Once again, thanks for the post.
