Tomcat install

[lianseng]

I downloaded the complete distribution (with Tomcat).

As I already have a Tomcat 5 installation elsewhere, I added a Context Descriptor lps.xml to point it at
<install_dir>\Server\lps2-2

http://localhost:8080/lps/index.html works.

But clicking on any of the examples results in a "file not found" e.g.
Compilation Errors
E:\lps2.2\Server\lps-2.2\examples\components\combobox_example.lzx: The system cannot find the path specified

The thing is that the path indicated is valid and the file exists.

Any ideas what I did wrong ?

Thanks.

Could there be some permissions problem on your directory?

[bloch]

Can you send along your context descriptor?

You can also look in the tomcat logs to see what LPS thinks is it's "LPS_HOME" directory.

Tomcat log:-
2004-10-07 20:56:30 StandardContext[/lps]LPS: LPS_HOME is E:\lps2.2\Server\lps-2.2

Seems ok.

My Context descriptor lps.xml:-
<?xml version='1.0' encoding='utf-8'?>
<Context displayName="LPS" docBase="E:/lps2.2/Server/lps-2.2" path="/lps">
</Context>

Thanks for any advice.

Can you peak at

...\lps-2.2\WEB-INF\lps\work\logs\lps.log and see if there are any ERROR of note ?

Wierdest thing is that when I clicked "View Source" on the error page, the correct source came up

[lianseng]

No errors, but combobox example cannot be found :-

Ok I just saw the post about Java 1.5 not supported. Is this it ?

Thanks again

[bloch]

Yep. 1.5 won't be able to compile any apps.
It will serve up precompiled apps ok. But won't be able to compile.

-Eric

[bloch]

But it's still strange that you're getting the error you're seeing. With 1.5 beta 2, the compiler generated a stack trace inside jython.

-Eric

[lianseng]

Cool real time support !

I'm on the jdk 5.0 release.

[lianseng]

No that wasn't it !

I just switched back to 1.4.2_05.
Tomcat and lps uses that now looking at the logs.

Same error.

[bloch]

You might also be running out of memory. 64 MB isn't enough, in general, to run the compiler with much frequency.

E

[lianseng]

Hmm, still on this !

I made changes in catalina.bat to increase the memory. No go.

Is there anyway to increase the level of logging ?
What does it mean when it says "<some path>:The system cannot find the path specified" on the browser ?

The file definitely exists and "view source" shows it.

Thanks.

[lianseng]

ok final update.

I reinstalled Tomcat 5 and everything is fine now.
I guess I'll never know what was the problem since I had a few other libraries in the old installation.

Thanks all.

Steps to reproduce:

get core only
untar tomcat
untar lps-2.2-core
move lps-2.2 directory to tomcat webapps directory
start tomcat
browse to LPS app, select demos.
try to run any of the demos.

End up with something like the following message:

Error: D:\Java\jakarta-tomcat-5.0.28\webapps\lps-2.2\demos\dashboard\dashboard.lzx: The system cannot find the path specified

Attached are lps.log and tomcat log files.

[lianseng]

Not sure if this was one of the things I did to solve my problem.

I zapped the cache directory and deleted the lzo file as well so that the LPS recompiled everything again.

Anyway mine installation has been running fine since I reinstalled and got knows what before that.

The "file not file" message is very misleading, because I'm very sure the file was there.

[wpoziombka]

Thanks for the suggestions but they didn't help to me.

[aprasadh]

I had the same problem. As mentioned in some other thread, creating "temp" directory under tomcat root folder solved my problem.
