Jasper Reports : Unable to upload jrxml file

ERPNext Reports
21

Hi @itsdave.

In your case, some how, it is not finding mysql/mariadb driver. Has you can see in the case of krithi_ramani pyjnius find the driver. I set java to throws all the erros to python and if any occur i send it to javascript client.

Please check console/terminal output for printed CLASSPATH and see if /.../frappe-bench/apps/jasper_erpnext_report/jasper_erpnext_report/java/lib/* is there.

There is no need to set the CLASSPATH in multiples files, set only in one of them.

@krithi_ramani, i test it with Cherry report (I made a new one) and everything is ok and i can generate the report too. Please try also with Cherry.jrxml to see where is the error and also update to have java errors reports to client.

Thanks,
Luis.

Hey Luis,

I understand what you are saying, and i know that the CLASSPATH has to be set only once. But as i have learned from this discussion…

…i had to export it the init script of supervisor too. I just wanted to say that i exported it in all known files to make sure that is has be available for frappe.

Im logging in as the frappe user, doing “env”

CLASSPATH=/home/frappe/frappe-bench/apps/jasper_erpnext_report/jasper_erpnext_report/java/lib

in this folder are serveral .jar files like

mariadb-java-client-1.1.8.jar
or
mysql-connector-java-5.1.38-bin.jar

I do the bench start from this session and i get the the same exeption again.

So i do think that the classpath should be OK in this case?

@krithi_ramani did you even try to generate one report despite not beeing able to save it after the upload of a file? It should appear in the according doctype even if not saved a second time. Maybe you would get this error too?

Luis, as @krithi_ramani an myself cant press the save button again after uploading a report-file, and this seems to be neccessary i wanted to point out that there can be at least two reasons for this Java-Exeption:

  1. CLASSPATH or .jar missing/wrong

  2. Wrong/missing connection String:
    I guess Java doesnt even know which connector to use, because there is no connection string displayed in this exeption.
    It it could not find the mysql-connecter, it should be more like:

    no suitable driver found for jdbc:mysql://localhost:3306/mysql.
    instead of just like

    no suitable driver found for

I guess this is the case because of the save function after uploading a file cant be called because of the missing button. (krithis point no. 2)

There must be still some problem:

-create a new report
-press the save button
-upload cherry.jrxml and the other report files

Here ist the problem:

-report shows as unsaved in the upper left corner
-save button is not displayed
-Ctrl+S leads to permission error
-Query Field is just an empty yellow area, other fileds also empty
-report is in tabJasperReports and can be selected in the according doctype for printing, but throws exeption.
-report is not shown in the Jasper Reports, and so it cant be edited after you leave it once
-if you try to create a new report with the same name you get a duplicate-entry error.

I suspect that there is still some function which has to be executed, before the report is even able to work? Is it possible that there is still a permisson missing or something that you might not have seen in your last fix? Shouldnt i be able to save after i uploaded some files to a report?

I guess, Im in a similiar situation like krithi_ramani…

If it helps to troubleshoot the issue and you would like to take the time, i could provide you a fresh install of Debian Jessie with this setup and ssh access to it.

Please tell me, if can help somehow to get it working or if you have some ideas left for troubleshooting

Thanks, David

Should be: /* at the end.

CLASSPATH=/home/frappe/frappe-bench/apps/jasper_erpnext_report/jasper_erpnext_report/java/lib/*

But i will see what maybe wrong. With me everything is ok, but as i said i will check.

Note: When you upload a jrxml file as in your case jasper is called to compile the .jrxml file to .jasper, but in your case, because java don’t find the driver jasper don’t compile and you don’t get the save button enabled.
So please check in folder frappe-bench/sites/name of your site/jasper/name of report/compiled/ for the name of your report.jasper file. If do not have .jasper file or compiled folder then you must find out what is wrong with CLASSPATH… I need more info to find the error. Put some prints all the way to generate the report. Let me know if you want that i tell you where to put them.

Frappe team have been made some change and i have been adapt my jasper to that. Maybe i miss some thing.

Also update jasper again, because i think you don’t have the trace error feature. When i removed mariadb client driver i get the error and you should get in client this:

Error in report Cherry Local, error is: Traceback (innermost last):

And yes you do not have a connection string because your .jrxml file do not compile. One condition to have connection string is to have query string. If do not compile do not save then you don’t have connection string.

Thanks.

Hi @krithi_ramani.

If you still get the same error after test with Cherry.jrxml, see if you have the report compiled in frappe-bench/sites/name of your site/jasper/name of report/compiled/ with .jasper extension.

Thanks,
Luis.

Hi @luisfmfernandes,
Am held up with a different issue. please give me some time to get back to you on this.

Thanks
Krithi

You are right, i missed “/*”.

Now my variable looks like:

CLASSPATH=/home/frappe/frappe-bench/apps/jasper_erpnext_report/jasper_erpnext_report/java/lib/*

No change.

I allready have the (btw very usefull) feature with the trace error display.

The error is simmilar to the error which was displayed at console level before:

Error in report Cherry_Test, error is: Traceback (innermost last):

As i wrote some days before: The report seems to compiled correctly. At least i have the .jasper file in this folder after upload. Its about 32kb of size.

What do you mean by “Put some prints” Sourcecode prints? Then it would be realy nice if you cound tell me the files and maybe positions where to put them.

Hi @luisfmfernandes,
Yes, I tried to add Cherry.jrxml and I could also see the compiled Cherry.jasper file in the mentioned folder. I get the following error in js console upon saving the page for the first time.

Uncaught TypeError: Cannot read property ‘clear_input’ of undefined

On uploading the file and saving(no save button here, saved as Ctrl+S) it again, I still get ‘No permission to ‘Save’ Jasper Reports’

Thanks
Krithi

@itsdave,@luisfmfernandes,

Solved! I unchecked ‘Apply User Permissions’ for the role in Role permissions manager. I could now save and assign parameters.

Thanks

Great! I can confirm that this works for beeing able to save changes to the report.

Just to mention it for someone who runs also into it:

Afterward i ran into the exeption when generating a report: Font ‘Times New Roman’ is not available to the JVM althoug i have installed mscorefonts on my system.

I was able to fix it by adding:

filename.Times_New_Roman=/usr/share/fonts/truetype/msttcorefonts/Times_New_Roman.ttf

to $JAVA_HOME/jre/lib/fontconfig.properties

Now the System shows:

Your report is ready to download. Click to download

But when i try to download the following error occurs:

@krithi_ramani did you try to generate a Cherry report?

30

@itsdave: You have to update frappe to the latest version. To show the pdf Report jasper_erpnext extends templates/web.html as frappe now support.

31

No @itsdave, I never tried Cherry.

@luisfmfernandes, I still have this problem of ‘Report already exists’ error. Once a report is created with a particular name and deleted, and if I try to create a new report with the old name, it says - ‘Report already exists’…There is no entry in the db either. Where else should the old report be deleted from?

32

@krithi_ramani. The problem is not with jasper. You delete a frappe doc (in this case a jasper report) direct in database.

So, please ask to frappe team, because i don’t know all the relational tables that was created with doc or metadata.

If you delete in normal way then you can create another report with the same name.

Thanks,
Luis.
