Unable to launch the Librarian GUI in Debian

SJV
Hello,
I am trying to make a fresh install of NewGenLib 3.0.4 (release 1 update 2) on Debian Squeeze (6.0.8), but cannot launch the librarian GUI. When I open http://localhost:8080/newgenlibctxt/LaunchApplication, Java starts, but after a while I get an error "Unable to launch application NGL EE V3.0 Carbon". I found similar problems reported on the forums (with Windows, I think), but could not find a working solution.

I have followed the instructions on page http://newgenlib.wikia.com/wiki/NewGenLib_Installation_on_Linux, except for downloading JAVA SE 7 (jdk-7u45-linux-i586) instead of the outdated (insecure) JAVA SE 6, and installing postgresql-8.4 and postgresql-contrib-8.4 from Debian Sqeeze's own repositories, not postgresql8* from the external repo http://apt.postgresql.org/pub/repos/apt/ suggested in the instructions.
I managed to start the server with "~/NGL3/apache-tomcat-6.0.32/bin/./catalina.sh run". Then OPAC does open at http://localhost:8080/newgenlibctxt, but the client fails to open at http://localhost:8080/newgenlibctxt/LaunchApplication. I tried to open it with ~/jdk-7u45/jre/bin/javaws. Could you help me pinpoint what I am doing wrong?

In the User manual there are installation instructions for Red Hat 4.0 and Fedora Core 5, but they do not seem to be applicable for Debian or Ubuntu. (I wonder also what is the "folder LinuxInstallation from the CD" mentioned in the RH/Fedora section in the User manual.) I read also http://www.verussolutions.biz/kb/ubuntuInstallation, but I think there is some mistake on line "......../InstallNGL3.0/apache-ant-1.8.1/bin/./ant UpdateWholeRec -f Instalation.xml". (Besides, the installation instructions for Ubuntu lack some details that are mentioned on http://newgenlib.wikia.com/wiki/NewGenLib_Installation_on_Linux).

Thanks in advance. With best regards,
Samu Virokannas

Respected Patron,
1: Is the OPAC running? http://localhost:8080/newgenlibctxt

2: Once you get an error "Unable to LaunchApplication", you will see an option to view Exception. Please send it

3. Also, Kindly send the screen shot of the Error dialog

1. Yes, OPAC is running at http://localhost:8080/newgenlibctxt/.

2. At the error dialog Details -> Exception:

Re: Unable to launch the Librarian GUI in Debian

SJV
Thanks for helping, but it did not work. I cleared the browser's whole history, but I still get the same error: Unable to launch...

Do you think the problem could have something to do with the Java version I am using? Or is there something missing in installation instructions I followed on page http://newgenlib.wikia.com/wiki/NewGenLib_Installation_on_Linux?

Re: Unable to launch the Librarian GUI in Debian

Verus Open Source Support
We are presuming that you are using the NGL 3.0.4 (or later releases). Please let us know the version downloaded.
Please try the below steps;
1. Stop Apache Tomcat server
2. delete the following directories
newgenlibctxt present in NGL3/apache-tomcat-6.0.32/webappps directory
newgenlibctxt present in NGL3/apache-tomcat-6.0.32/work/Catalina/localhost directory
3. Start Apache Tomcat server

Try to launch the application again. Also, did you try launching the application from any other client system(connected via LAN to the server)?

Re: Unable to launch the Librarian GUI in Debian

SJV
Sorry, I still didn't manage to launch the application.

1. I stopped Apache Tomcat with ~/NGL3/apache-tomcat-6.0.32/bin/.shutdown.sh, and also
..../catalina.sh stop (though I don't know if the latter was necessary)
2. Deleted the both newgenlibtxt directories.
3. Restarted Apache Tomcat (~/NGL3/apache-tomcat-6.0.32/bin/.startup.sh) and Catalina (export JAVA_HOME=.../jdk1.7.0_45/, and then  ~/NGL3/apache-tomcat-6.0.32/bin/.catalina.sh run)
http://localhost:8080/newgenlibctxt/LaunchApplication still gives me the same error message (Unable to launch...) and exception (java.lang.SecurityException:... unsigned entry in http:localhost:8080/newgenlibctxt/Date_selector.jar) as before.

I downloaded InstallNGL3.0.zip from the link http://www.verussolutions.biz/downloadNGL.php on page http://newgenlib.wikia.com/wiki/NewGenLib_Installation_on_Linux. The link did not give me an option to choose which release to download, so I suppose I got the newest version. For me it seems the download link points at the same zip file as on the installation instructions for Windows at http://www.verussolutions.biz/web/content/download -> 3.0.4 Release1 Update 2 "Install NGL" ->  "Download NGL3 from this link".

As for Java, I downloaded the newest Java SE development kit http://download.oracle.com/otn-pub/java/jdk/7u45-b18/jdk-7u45-linux-i586.tar.gz, which was unzipped as directory jdk1.7.0_45 to the home directory.

I tried to launch the application only locally from the very same computer where I installed the NGL server, not via LAN. (This is a stand-alone installation for testing purposes.)

Samu Virokannas

Dear All,

After I updated my java to the latest7u45 on my client, even I am unable to launch the application, and getting the same error, where as, I am running NGL server on Ubuntu with Java6 , where I am able to launch the application.
Is any body else facing the same issue?
Verus Team mighht working already on this issue,

Please help us resolve it ASAP, I atleast need 2 clients running at the same time, and I am having 12 clients running parallely .

Thanks in advance,

Is your Debian Installation 32-bit or 64-bit?
Accordingly Is your JDK installation 32-bit or 64-bit
They both of them should match. Kindly check this

Re: Unable to launch the Librarian GUI in Debian

In reply to this post by Verus Open Source Support
As far as I understand, both my Debian and Oracle JDK are 32 bit. (The command uname -m outputs i686, and getconf LONG_BIT outputs 32. Java: installed jdk-7u45-linux-i586.tar.gz, not jdk-7u45-linux-x64.tar.gz.)

I tested also jdk-7u40, and it turned out that NGL does actually open with 7u40. However, I am worried about the security issues (and future Java incompatibilities) - please see the screenshot below:

Launching NGL with jdk-7u40


(With jdk-7u45 I did not get this kind of security warning, but instead the NGL client simply could not be launched, as I described earlier.) When I checked "I accept the risk..." and clicked "Run", NGL started and asked IP & port number, then user ID & password, and I managed to log in. Once logged in I could confirm NGL version is 3.0.4 Carbon release 2 update 1.

Overall, NGL seems to work with jdk-7u40 (or earlier, I suppose), but not with jdk-7u45. I think this could be a messy issue, as people generally update Java to the newest version for security and bugfixes.

In Oracle's JDK 7u45 release notes http://www.oracle.com/technetwork/java/javase/7u45-relnotes-2016950.html there is some probably relevant information, but I don't quite understand the suggested workaround. It seems the issue has roused quite a lot of discussion on various forums, see e.g. https://forums.oracle.com/thread/2593583 or http://pitss.com/us/tag/java/.

Is it really safe to run NGL with older JDK versions that probably have unpatched vulnerabilities? What kind of risks that concretely involves? On the other hand, what should NGL users do in order to be able to launch the NGL client with the newest jdk?

Or do you think the problem could be circumvented by using Open JDK instead of Oracle’s JDK? If so, how should NGL be configured to work with Open JDK?

Best wishes,
Samu V.

Kindly go ahead and launch the application. We will fix the update with a new keystore.

RE: Unable to launch the Librarian GUI in Debian

SJV

Thank you very much. I shall go on testing NewGenLib.

 

My organization needs an ILS, and I am investigating, which one would be the most suitable for us. So far NGL seems quite a promising project, though e.g. Koha has the advantages of wider user base and better documentation. Please keep up the good work.

 

Samu V.
