LAZY Classloading failed error when opening integration builder. Please help!

[gopalkrishna_baliga]

Hi Experts,

   My system got recently updated with Java 7 and after that whenever I try to open PI 7.31 integration builder I get below error:

   LAZY CLASSLOADING FAILED

   I am not able to open integration builder as well as repository.

   It was working fine earlier with Java 6.

   How to fix this?

   Is there a way I can install both Java 6 or Java 7. But use Java 6 for PI and Java 7 for browser and other applications?

   What setups I need to do for this?

Thanks

Gopal

Hi Gopal,

You can download and install the jre version compatible with your PI system.

When you are in the home page of your PI screen - rather rather than doing a left click and opening the Integration Builder link - right click and Save As the jnlp file in your local machine.

Right click and open the jnlp file with the "javaws.exe" file in the bin folder of whichever java (jre version) you want to use. You would see the webstart would be launched of the version you selected.

I uninstalled java completely and reinstalled Java7. The restarted my system. Now I am getting below error:

CouldNotLoadArgumentException[ Could not load file/URL specified: http://sapxxxxxxx.com:8xxx/rep/start/repository.jnlp]

What could be the issue now?

Hi Gopal,

Assuming that you can open the link in http://sapxxxxxxx.com:8xxx/dir/start/index.jsp from your browser and this is not a firewall issue - can you try using a browser other than Internet Explorer.

Hi Gopal,

You are facing this issue because of java version. the latest update which is available java 7 update 25 has bugs, to fix that you need to download java 7 update 40 and install it.

it will work.

you can download the same from https://jdk7.java.net/download.html

Hello

See the note 1883576 LAZY_CLASSLOADING_FAILED error opening PI Integration Builder tools. There are some issues with the later versions of Java 1.7. Use a version earlier than 1.7.0_21, if possible.

It is possible to have 2 Java versions installed on your pc but you need to disable the unwanted Java version in the Java console. See note 1614742 Using Java Web Start with different PI releases. If there are two Java consoles (one for 1.6, one for 1.7), you will need to ensure the unwanted version is disabled on both.

See also Troubleshooting PI ESR and Integration Builder Logon Issues. Delete the caches on the Java consoles and try to logon again.

Hi

This problem is due to Java web start cache issues. What is your PI version and what java jre is installed in your client machine. Uninstall your java in control panel and restart the system and again install required java.

Once again restart the system and try.

This problem is due to automatic java update from internet.

I hope this will work

Yes I have seen that. but it did not fix my error.

The error says:

LAZY_CLASSLOADING_FAILED

CHECK_LOG

Where do we see the log? Is there any folder where java logs are stored?
