    I have seen multiple posts on this in the J2EE forum, but no clear answer.

    When I update a jsp page, the cpu starts cranking at about 99%. It usually takes between 30sec to a minute to complete whatever the heck it is doing in the background. I have turned off JSP validation, so I don’t know why it is doing this.

    Here is my setup:
    XP Professional SP2.
    1 Gig of RAM.
    Pentium Centrino 1.6 MHz processor.
    Eclipse 3.06
    MyEclipse 3.84
    I have no other plugins installed, and I installed MyEclipse with a clean version of Eclipse.
    JDK version C:\j2sdk1.4.2_04

    I am starting Eclipse in the following way: eclipse.exe -vmargs -Xmx256M

    This doesn’t happen everytime, but I would say that it happens close to 50% of the time.

    I have turned off real time virus scanning.

    This problem also occurs when I change to the default html editor.

    Any idea what may be causing this?

    Here is the log file for the las time that it happened. (Mind you, I am not using the JSP editor but instead have switched to the plain old html editor).

    What is the Build ID and version information from the Window > Preferences > MyEclipse menu? THis sounds exactly like a bug in older version of MyEclipse that we had… and a few of your versions given above are incorrect so I’m hoping you aren’t actually running MyEclipse 3.8.4 and instead are running an older release (so we can upgrade it and fix the problem).

    This all looks kosher, can you post an example page that is causing this issue so I can try it here locally?

    I’m having a similar problem. All I have to do is start typing something in a JSP file and my CPU usage goes way up. The app gets so slow that it’s about 20 or 30 characters behind my typing. This is not fun for development. We are actually trying to switch to eclipse from JBuilder. Last year when I used MyEclipseIDE for JSP Development I didn’t have this slowness problem. I’m really hoping there is some answer to this problem or we may have to go back to JBuilder or find another eclipse product.
    Please help if you can.

    thanks

    rpray,
    I would encourage you to upgrade to QF2 and see if the problem fixes itself:

    I read my version from the wrong place. In the MyEclipse preferences it says:
    Version: 3.8.4+QF2
    Build Id: 200502031200-3.8.4+QF2

    I tried to send you the text of one of my files, but it keeps giving me an error that says I don’t have permission to access Index.php. One thing about my files that might be of interest is that they all include java server page fragments for header and footer.

    thanks.

    rpray,
    Ok you are fine then. If you can create a small sample VALID project that is compilable and then export it (File > Export > to ZIP) you can email it to support@genuitec.com ATTN Riyad and I’ll take a look at it. Don’t forget to include a link to this forum post.
