NullPointerException at start of Talend Studio

Anonymous — Sat, 16 Nov 2024 07:12:52 GMT

Every time i launch Talend Studio i get a dialog box with the only text: "java.lang.NullPointerException" and an OK button.

The dialog comes before the "Select Project" dialog.

I click OK and Talend Studio launches as normal.

OS: Windows 10 x64

Java: 1.8.0_191

Talend Studio 6.5.1

@Slup,how long are you getting this? have you import any custom components?

It has been for a couple of months.

And it has occured both before and after a reinstallation of Windows (change from Windows 8.1 to Windows 10)

I have installed all additional packages and a couple of jars related to the use of job component.

No other custom components though.

@Slup,may be your Talend is not recognition Java or Java home path..you can try the by re-installing Talend.

I have tried reinstalling. The problem persists.

I do not think it is a problem with the jdk/jre because Talend Studio starts as normal, start up is just interrupted by a dialog with the NullPointerReference.

Hello,

It seems to be the corruption of Workspace directory. Could you please upload your whole error log? Are you using talend open studio V 6.5?

Best regards

If it is corruption of workspace it is the second workspace I have had corrupted this way.

Since the problem persisted after a reinstall of Windows.

Where do i find the whole error log?

I am using the enterprise edition of Talend Studio

Ï found a log file which matches the NullPointerException

It reads:

@Slup,it is not able to validate the license.

Re: NullPointerException at start of Talend Studio

But Talend Studio starts up fully licensed for Integration and ESB work, which is the license we bought (after i click OK on the NullPointerException).

And if that is the problem then there is a UI bug, because the alert box is not very informative:

Hello,

Could you please give us some detailed steps to repro your issue?

Are you using SVN as repository or it is local connection?

Best regards

Hello,

As we known that studio must get the git user name from TAC at least, are you setting "GIT login" and "GIT Password" for your user?

Here is online documentation about:TalendHelpCenter:Best Practices: Using Git with Talend 6.2 and later versions

Best regards

Yes I have entered my GitHub login into TAC.

I have no problem connecting to TAC and selecting my project and working with Git even with a local branch

I have a very similar issue, for me it's like this:

I launch Talend Studio

The splash screen comes on

(wait a long time)

git password pop-up

The NullPointerException dialog comes on

I click OK

git password pop-up again

The "Select Project" screen comes on

I select project

Talend Studio comes on

Did you have any success resolving this in the mean time?

I will write back here as soon as I know more

The problem was due to Workspace corruption.

Solution:

Create a new Workspace from scratch
