I have same problems. But one additional thing is, upon opening, it always auto compile all java and jsp pages. Anyway to stop the auto compilation?

[support-michael]

Disable/Enable the “Jsp compilation” preference at Windows>Preferences>MyEclipse>Editors>JSP/HTML.

Another question on the “slow editor opening” issue, how many taglibs are declared by your JSP and how many taglibs in your project?

[No Operation]

I used copy and paste and created a JSP file from your post.

Then I did some measurements:

1. Test open a Java file:
– close project
– open project
– open a Java file

duration: from 2 to 8 seconds.

– close that Java file and open it
– open that Java file again

duration: less than 1 second.

1. Test open a JSP file:
– close project
– open project
– open a JSP file

duration: from 3 to 6 seconds.

– close that JSP file and open it
– open that JSP file again

duration: about 1 second.

so JSP files do open slightly slower here, but at acceptable performance.

I am using J2SDK1.4.2_02 and running Eclipse with:

C:\eclipse2.1.1\eclipse.exe -vm \j2sdk1.4.2_02\bin\javaw.exe -server -Xmx1024m

I suffer from the very same problem. Every jsp which has cusstom tags on it takes in excess of 20 seconds to open. This is just unusable. Has this been reproduced by the development team yet?

[Scott Anderson]

Has this been reproduced by the development team yet?

Yes, it has. It is related to be related the the number of nested tables in use in the JSP page. One of our kind users in Germany sent us a JSP page with 5 levels of nested tables that reproduces the CPU lockup problem that others have reported, and this slow opening is related. We’ve got several test cases set up and the bugs have been posted to the tracking system. The development team has already begun working on them.

We apologize for the inconvenience and thank you all for your support and postings that helped us to isolate this issue. As soon as it is fixed and tested we’ll issue a special patch release.

Scott,
Thanks for your quick reply. I’m currently evaluating myEclipse for my hobby project. I’ll definitely buy the subscription once this issue is fixed. MyEclipse is really slick otherwise 😀

[support-michael]

We have also identified a potential optimization that we believe will accelerate JSP editor launch performance. We are researching it further and believe it will dramatically improve this situation.

I’ve found that 2.6.4 fixed my speed issue with opening and editing JSP files. Things are working great now. Thanks!
