Installation error?

[aapatel]

Hello,
I just downloaded lps-2.0p and copied the lps-2.0p webapps dir to my tomcat 4.0 webapps dir, result on attempting to load any lzx files:

Error: org.iso_relax.verifier.VerifierConfigurationExcept ion: no validation engine available for: http://relaxng.org/ns/structure/1.0com.laszlosystems.utils.ChainedException: org.iso_relax.verifier.VerifierConfigurationExcept ion: no validation engine available for: http://relaxng.org/ns/structure/1.0

I would appreciate it if anyone could provide any insight into this issue.

Thanks in advance.

Hi Ankur

You did download the LPS-2.0 core, right?

-Antun

[aapatel]

No, I had only installed the DE version.
However, I just did download the Core version and copied the lps-2.0p directory to the webapps directory - upon going to the Welcome page, the result was just a blank page. The tutorial page renders the lzx code-text instead of displaying instances of the lzx components.

We appreciate your prompt reply.

Hi Ankur

Did you restart Tomcat?

-Antun

[aapatel]

yep!

[antun]

OK, could you tell me what jars there are in the common/lib/ and server/lib/ directories of your Tomcat installation?

Thanks,

Antun

Hi Ankur,

What version of the JDK/JRE are you using?

Hi Ankur

OK, we've been able to reproduce the problem, and are now looking into it. Initially, I installed on Tomcat 4.1.29 to see if I could replicate your issue. We subsequently found an archived version of Tomcat 4.0, and tested with that.

Right now there are two ways that you can run the LPS:

- Install the LPS DE (not core), which installs Tomcat 4.1 for you.
- Install a version of Tomcat 4.1 yourself, and install the LPS core on that.

I'll let you know when we find out what the problem is. Thanks for your patience.

One other thing you might want to try is to copy jing.jar from the lps webapp/WEB-INF/lib/ to $TOMCAT_HOME/common/lib.

-Antun

[aapatel]

copy'ing jing.jar did not prove any better results. We are using tomcat 5.0.16.

Hi Ankur


We are using tomcat 5.0.16.


I'm not sure if this was a typo, but in your original post you said Tomcat 4.0. The LPS isn't formally tested against Tomcat 5.0 as far as I know. See the "Certified Application Server environments" section here:

http://www.laszlosystems.com/developers/download/#decore

We do plan to formally support Tomcat 5.0 soon.

-Antun

[aapatel]

I had originally tried it against a 4.0 and then attempted to use it against a 5.x version.

So for the time being, the only way seems to be by using an lps de version - the one where the lps web app comes packaged with a tomcat engine pre-bundled?

ankur

[antun]

The DE bundle should work right out of the box for you, so if you want to get started quickly, that would be the best thing.

However, as I said, we have been able to replicate the problem and are looking into it.

When you said:


copy'ing jing.jar did not prove any better results.


... were you referring to Tomcat 4.0 or 5.0?

Thanks for your patience in this.

-Antun

[aapatel]

I apologize for the vagueness - that was against both the implementations - 4.0 as well as 5.0.

Hey Ankur

Could you tell me what OS and JVM version you're on?

Also could you restart Tomcat, then upload a copy of the Tomcat log? The log would be something like:

YOURTOMCATDIR/logs/localhost_TODAYSDATE.txt

Take care,

Antun

[aapatel]

OS: Solaris 8
Java version: build 1.4.2-b28

[antun]

Thanks. One more thing - could you also upload the LPS log which lives at:

/home/aapatel/projects/jakarta-tomcat-5.0.16/work/Catalina/localhost/lps-2.0p/LPS/logs/lps.log

Take care,

Antun

[aapatel]

lps.log attached. I apologize for not looking @ this log file myself.

[antun]

OK, here's one more .jar to move around:

Take:

lps-2.0p/WEB-INF/lib/xalan.jar

... and copy to:

YOURTOMCATDIR/commmon/endorsed

Then restart Tomcat. Let me know if that works.

-Antun

[aapatel]

Tadah! That worked! Just as recieved your note, i had moved over the Xalan.jar over the endorsed directory and it worked! Great, appreciate your help.

By the way, I just realized that this was apparently a known issue. It's in the installation instructions for core:
