Hi,

After purchasing and installing the MyEclipse plugin, anytime I try to open a JSP file which contains references to taglibs, my IDE hangs indefinitely. JSP files without taglib declarations open just fine.

<%@ taglib uri="http://jakarta.apache.org/struts/tags-bean" prefix="bean" %>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html" %>
<%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic" %>

I thought it might have something to do with validation so I switched off all validation in the preferences section but the problem persists. It’s fairly awkward having to edit these files in another editor. MyEclipse seems to have taken valuable functionality away rather than help! Any suggestions on how to fix this?

Thanks a million,

Stuart.

Stuart,
Something funky is going on, clearly we wouldn’t have much of a J2EE IDE if it couldn’t edit these pages 😉

Can you please post all the information we request in the [URL=http://www.myeclipseide.com/PNphpBB2+file-viewtopic-t-393.html]Posting Guidelines[/URL] thread at the top of this forum? That will give us some context so that we can determine if this is an installation issue, a configuration problem, or a bug. Thanks.

Stuart,
I’d like to rule out a few things right off the bat, then if necessary have you send me this project to see what might be going on.

What command line args do you use to run MyEclipse? We suggest using:
-vmargs -Xmx256m

Try and open a problomatic JSP page, then comment out all the @taglib lines at the top, save it and reopen it with the JSP editor, did it work? Now close it and edit it again and add 1 JSP line, save reopen with the JSP editor. Did that work?

When the workbench freezes up, do you see any messages anywhere? Maybe down in the status bar? Do you see “Building workspace…” anywhere? If you fire up task manager, does the Eclipse java process take up any processor time? Is it pegging your CPU or just sitting there idle?

[sbarlow]

When running eclipse I specify the vm to use and also the location of the workspace:

“C:\Program Files\eclipse\eclipse.exe” -data C:\workspace -vm C:\bea\jdk142_05\jre\bin\javaw

eclipse.ini file looks like:

-vmargs
 -Xms256m
 -Xmx768m

I tried opening the file as suggested. It hangs with the @taglib lines in the file and opens OK with them gone. Not sure what you mean by “add 1 JSP line”. I tried to add a random bit of JSP (<% … %>) and reopened in Eclipse OK. But when I add in a single @taglib line and try to reopen, it hangs again.

When the workbench freezes, I see the windows busy hourglass icon and no new information messages in the status bar. What ever was in the status bar when I try to open the file, remains. I checked the processes and there’s no unusual increase in the CPU level for the two processes running (java.exe and javaw.exe). CPU time and mem usage remain static. If I switch applications away from Eclipse and try to go back again, it doesn’t appear.

[Riyad Kalla]

Ok 2 more suggestions just for sanity sake.

1) Download JDK 1.5_04 from Sun’s site, install it and use it as your -vm target in your shortcut for Eclipse.

2) Move your eclipse.ini file to your desktop, and temporarily add

-vmargs -Xms128m -Xmx256m

to the end of your MyEclipse shortcut, so the whole thing would look like:

 "C:\Program Files\eclipse\eclipse.exe" -data C:\workspace -vm C:\jdk1.5.0_04\bin\javaw.exe -vmargs -Xms128m -Xmx256m

NOTE: For path-safety sake (no spaces) I am assuming you installed the JDK to C:\ instead of the new default of C:\Program Files that the installer suggests. If you do use Program Files please quote the path.

NOTE: I’d really like it if you could make your shortcut look identical to the one above (sans the path issue if you choose), same memory values, same javaw.exe and note I”m using the jdk\bin dir, not the jdk\jre\bin dir as your shortcut did.

I’d like to get you setup exactly as I am here, rule out every possibility. The fact that you are using the JDK that ships with your app server is in question, you are never sure if they are customized the JDK in any way. IBM is well known for doing thsi with their JDKs they ship with WebSphere; in that they are heavily engineered to work with the app server a certain way. So I tend to prefer “vanilla” installs of JDKs to run the IDE to rule out any weirdness… even soemthing as small as custom XML parsing libraries.

[sbarlow]

Hi, I bet you thought I’d gone away!! I was away and busy with another project but I eventually found time today to get back to this issue and test the things you suggested. After making the changes you described, the problem still occurs. I tried to open a largish JSP file over five minutes ago but I still see the busy hourglass cursor when I swap back to Eclipse.

[Riyad Kalla]

Can you send us the JSP or a small project that exhibits the problem so we have an exact replica to test against?

Also please check your log file: <Workspace dir>\.metadata\.log, see any exceptions near the bottom that might help us figure out what is going on?

Thank you for the snippet, I pasted it into a new JSP file in a new Struts project and was able to open/design it fine. I would mention that I noticed some EFM/GEF (maybe JEM) conflicts in your log file, MyEclipse ships all these libs so you are encountering conflicts by having them installed separatly. I would also note that your ration plugin was throwing some exceptions as well, I’m going to estimate that there is some setup issue here that is causing the behavior. I would suggest a clean install of Eclipse 3.1 SDK (redownloaded) and MyEclipse 4.0 GA along side your current install, create a new workspace and use File > Import to pull in your projects, then try editing the file again, did it work?
