[resolved] cannot start Talend

izumisawaa — Sat, 16 Nov 2024 13:19:10 GMT

Hi
I cannot boot talend's start-up screen.

I confirmed talend's log file.
- ${LAST_TIME_TALEND_WORKSPACE}/.metadata/.log
The final root cause: rg.eclipse.core.internal.dtree.ObjectNotFoundException
-'/${LAST_TIME_TALEND_WORKSPACE}/metadata/connections/${CONNECTION_NAME}_${VERSION}.properties' was not found.
But, That properties File is found!!

I cannot use Studio at all.
Please teach what I should do.
Regards

Hello

I confirmed talend's log file.
- ${LAST_TIME_TALEND_WORKSPACE}/.metadata/.log

I don't know what you have done. Why did you re-configurate the location of log file? Just reinstall TIS Studio should fix the problem.

Hi,

I don't know what you have done.

There was an error before closing TIS last.
TISfailed to retrieve schema.
(but,the database was active)
Then I will not restart.

Why did you re-configurate the location of log file?

What does this mean?

Just reinstall TIS Studio should fix the problem.

Just reinstall , I can use TIS.
However,I can not import all the items failed project.
Do I have to do start from scratch?
(metadata,context,job........)
regards

Are you connecting to a remote project or local project?
- If it is a remote project, the project is stored on svn server, you can re-configure the remote connection and retrieve it from svn server again.
- If it is a local project, what's error do you get when you import all the items.

Hi Shong
Thank you for reply.
It is a local project.
The item list is empty though I selected the directory of the project.
The message is displayed in Japanese.
The meaning of the message is "No items available";

Hi
It is a local project, why don't choose the workspace and open the project directly?
Best regards

Hi
I mean choose the workspace which contains the project and then select the project and open it directly, why do create a new project and import all items from old project?
Please see my screenshots.
Best regards

Hi Shong
When reinstall , I tried to the two
1.I create new workspace(and project) and import the project. but item list is empty.
2.I choose the project.but I cannot choose the project because error.
The topic returns first.

I cannot boot talend's start-up screen..

I can see splash screen.
I cannot see start-up screen, So I can not switch other project.

When I choosed the workspace which contains the project, I can not use TIS never.
TIS doesn't find the property file of the connection that fails in retrieve schema.
I am going to reinstall repeatedly.

TIS doesn't find the property file of the connection that fails in retrieve schema.

Are you creating a local connection? right?
Go the TIS studion installation folder/configuration and see if the file connection_user.properties exists, if so, delete the file connection_user.properties, restart TIS studio, create a local connection again, select the workspace which contians the project.

Hi,
Yes, I have only local workspace.
The result was the same though it deleted files(connection_user.properties and items) like your instruction.

Hi
OK, now I show you a way of restoring all the items:
1. Create a new project and login the project.
2. Go to workspace/old_project_folder/metadata/ and copy all the folders.(pic1)
3. Open the Navigator viewer of new project, open the new_project_name folder/metadata, right click on the metadata folder and paste them.(pic2)
4. Use the same way to restore all the items of code, context, joblet.
5. Finally, restore the job items, go to workspace/old_project_folder/process/, copy all the folders and items or some of items which you want to restore.
Open the Navigator viewer of new project, open the new_project_name folder/process, right click on the process folder and paste them.
6. Go back to Repository viewer and refresh.
Best regards

Hi,

My Workspace revived by having taught to you.

3. Open the Navigator viewer of new project, open the new_project_name folder/metadata, right click on the metadata folder and paste them.(pic2)

=>I re-made connection because I had made an error of the copy of metadata.
Additionally, there is no problem.
Thank you very match!
