RE: Getting Null Pointer Exception while starting Liferay DXP server

2019-10-18T09:41:44Z

I have downloaded "liferay-ce-portal-tomcat-7.2.0-ga1-20190531153709761.7z" yesterday and just started the server without any DB configuration. it was started with hypersonic and end up with this exception.... i dont do any additional configuration. Any guess?

Hi Gnaniyar Zubair,Thanks for sharing the links, from the above feedback, some local investigation and the LPS ticket my sense is that this is related to McAfee AV. Possibly preventing the sql scripts executing correctly, I took the action of installing to a clean machine (no AV) and exporting the mysql DB, re-importing to the original machine got me over the hump albeit without fixing the underlying cause. Regards,John

John, there is a new Liferay DEVStudio out: Version: 3.3.0.201808240530-ga1 which may be of interest / use to you... -daniel

Hi Daniel,

Thanks for the update, I found that pre creating the LR tables allowed me to run the server locally. Still run in to permission errors when deploying portlets with DB changes.

Thanks for your help,

John

"I resolved the second problem by modifying build.xml and liferay-plugin-package.properties"

Hello pulkit tiwari,

Can you share with me on what changes you made to these files to resolve the "Unable to copy portal TLD aui.tld"?

I am currently running into this deployment error when going from Liferay 6.2 to 7.

Very much appreciated.

Thanks.

Hi Daniel, thank you for your update, Interestingly this issue does not appear when using the linux installer. I ran the LDS installer booted the application changed the database from Hypersonic to Mysql and restarted. On Linux this was no issue however on windows I get "invalid content in indexes.sql" message . In light of your last post I think i should perhaps move the question to its own post. Thank you for your assistance and responses.

Regards,

John

John O'Flaherty:

Daniel did you get to the bottom of this issue?

Hi John,

Our current path has shifted to 7.1 DXP. I have managed to install it using the 7.1 bundle from customer portal. I had a successful data upgrade and startup. Also, since we are near the beginning of upgrading plugins, we figure jumping on the later branch sooner will help us in the long run w licensing and supported platform into the future. Hope this info helps you. I also do not use the "Studio" bundle and just installed the IDE and "workspace" onto Eclipse. We may soon shift to Intelli-J, as well, though that setup is not full-featured yet...

RE: Getting Null Pointer Exception while starting Liferay DXP server

2018-08-16T15:01:23Z

Hi all,

Daniel did you get to the bottom of this issue? I too am experiencing the same NPE error. In my scenario I download the latest Dev studio and I got the web installer page running, i then proceeded to choose a local mysql server. Completing this step and rebooting i then began to see errors in the IDE console.

Amongst these were

BaseDB warnings regarding permission errors on frm files.
Following this I also see
- A sample message being : com.liferay.portal.kernel.upgrade.UpgradeException ( Bundle com.liferay.bookmarks.service_1.1.24 [60] has invalid content in indexes.sql )
- other bundles affected include wiki, calendar,
- I also get Caused by: java.sql.SQLException: Error on rename of '.\j2o_dxp_bundle_workspace\#sql-13ec_1f2.frm' to '.\j2o_dxp_bundle_workspace\calendar.frm' (Errcode: 13 - Permission denied)

I've attempted this a number of times and have not been able to get a DXP development environment functioning with Mysql, I have been able to get the default HyperSonic alternative to work. If possible I'd gratefully appreciate any assistance with this issue. A point of note perhaps was that when i ran the Liferay Developer Studio installer the attached popup was displayed

My Environment:

MYSQL DB 5.7
JDK 8 171
Liferay Developer Studio : 3.2.0.201807202141-ga1
Windows 10

Regards,

John

Yeah - especially when I have the 6.2 EE ldap working fine when I shut down for the upgrade.... Well, we are in production on 6.2EE and working the upgrade / development path to DXP right now. I have a working DXP SP6 unpatched bundle for development, so we can keep working.

Daniel Tyger:

We installed de-47 when advised about the security fixes, which broke our upgrade path, and we were then issued a patch on top of that.

Eek. One thing I always tell my clients, treat the fix packs as though they are code deployments.

Install the fix pack into a lower environment first and do testing, promote only when testing is successful.

This allows you to avoid having a non-working production environment because some change introduced by a fix pack is incompatible with your environment/custom modules.

Disabling the staging permission makes sense, the NPE would have been tied to a missing live group from the staging group (kind of weird, but okay).

But for the life of me I can't figure out why that would force a login portlet to become undeployed...

David, thank you, kindly.

We installed de-47 when advised about the security fixes, which broke our upgrade path, and we were then issued a patch on top of that. Our stack trace is a little different... I'll paste it below. A quick note though that the UNpatched SP6 tomcat bundle works fine for us, including the upgrade. It was only after moving up to more recent fixpack / patches did we encounter these similar problems... :

Also, I was advised to turn off the staging permission in the Gogo shell, which I did do while it was starting up, then we got a little further, but Liferay errors when it tries to load the sign-in portlet...errors like this...:

The sign-in portlet seems to partially appear, but you can not use it and a alert on-screen reads "Portlet is temporarily unavailable." I did check the db and that portlet is marked active...

Any ideas / suggestions?

Gratefully, -daniel

Daniel, can you share your stack trace? The line 132 of StagingPermissionChecker would not be valid for DE47...

RE: Getting Null Pointer Exception while starting Liferay DXP server

2018-07-02T19:32:12Z

We, too are facing the same issue (Liferay DXP 7.0 post de-47) and we have a support ticket in at Liferay, but still looking for help, here, too...

RE: Getting Null Pointer Exception while starting Liferay DXP server

2017-12-10T09:20:14Z

This is all on a thread referencing Liferay DXP: For those on Liferay DXP, have you opened a ticket with Liferay Support? Upgrades are covered by the support contract.
For all others: Have you tried this on the latest available version? Which version did you run the upgrade on? The upgrade routines are also updated with each new release that is available, but nobody here (including the DXP users) referenced a specific version (GA for Liferay 7 CE, FP for Liferay DXP), which would be interesting to know - especially as experience teaches that often posts here don't reference the latest version.

Its been 9 days and there is no reply on this issue from you guys. This error comes when server is started with normal database settings and all default settings.
I am unable to find any solution to this issue. Can anyone please look into this issue . It seems to be staging configuration issue.
