I've deployed UniTime 4.0 in my Glassfish Server successfully, and the timetable blank-data.sql database in my Mysql db engine.

According with the documentation everything is working on the server, but when I've tried to login to UniTime, login windows say:

http://myserver:8080/UniTime/login.do
User: admin Pass: admin (according with the documentation)

Authentication failed: Login Failure: all modules ignored.

PDT: My mysql database and Glassfish are not in the same server (both in diff servers), I've just edit the hibernate.cfg.xml into timetable.jar.
```

<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="connection.url">jdbc:mysql://x.x.x.x:3306/timetable</property>
<property name="connection.username">mydbuser</property>
<property name="connection.password">mypass</property>
<property name="connection.autocommit">true</property>
<property name="dialect">org.hibernate.dialect.MySQLInnoDBDialect</property>
<property name="tmtbl.uniqueid.generator">org.hibernate.id.TableHiLoGenerator</property>
<property name="hibernate.connection.useUnicode">true</property>
<property name="hibernate.connection.characterEncoding">utf8</property>
<!-- End of MySQL Configuration -->

Glassfish took the changes and not says errors or warnings.

May be it causes the issue?
Could you guys help me with this authentication issue?

Thanks a lot.

It will be really helpful if the class external ID can be displayed in the course timetabling pages:
UniTime/solutionReport.do
UniTime/timetable.do
UniTime/assignedClasses.do
UniTime/unassigned.do
UniTime/solutionChanges.do
UniTime/suggestions.do

Where in the UniTime is the division into groups? For Example : We have two groups in Preparatory Program: Group_1 and Group_2. Where can we add them to UnitTime to see in the schedule separately by groups?

I imported staff and courses to unitime by using xml iterface but unfortunately they are not visible? Are there any one who knows how to make those imported data visible?

It could be interesting if we can choose wich information appears in the description for a course related events in the timtable export ics. Now the description is "Course Related Event" and could be interesting show the title of the course related or the name. May be for the next version?

I am getting the error below while exporting an academic session in Version 4.2.104 built on Sat, 25 Feb 2017.
The error can be replicated in https://demo.unitime.org

Unable to export: could not resolve property: null of: org.unitime.timetable.model.ExternalDepartmentStatusType [select distinct q235.null from org.unitime.timetable.model.Session q0, org.unitime.timetable.model.Department q7 inner join q7.externalStatusTypes q235 where q7.session = q0 and q0.uniqueId = :sessionId]

Is it possible to add an option of running the solver for specific date pattern(s), i.e., without affecting the others?

If this is really an open source project, are their any development guidelines or instructions on how to get started with development/contributing? I don't see a basic "how to build" section in the README, is this buried somewhere else in the project or project website?

I have tried the example XML for buildings and rooms which is in this link https://www.unitime.org/interface/buildingRoomImport.xml but unfortunately i couldn't succeed. Are there any other way to do it?

I installed JDK, MySQL, and Apache Tomcat. And now when I get to the part where I run schema.sql in MySQL 5.5 I get an error that says:

**Error During "Run SQL Script"

error calling Python module function
SQLIDEUtils.runSQLScript**

Connecting an EXTERNAL APPLICATION to the UNITIME APIS, and indicate that UNITIME generates the schedule automatically.
Can you help me find a solution, thanks?

I installed UniTime. But i am getting multiple menu bars during login (ten to be exact). The footer also has the Version 4.4.114 built on Tue, 25 Jun 2019 to 10 times.

Some sections of the page (after loging) in also repeats itself.

Some fields inside also replicates itself. (see date field in the below image)

What could be the reason?

This Project is amazing! Thumbs up!
Could it be possible to add "subject area" in the "Resource" dropdown so as to enable filtering by Subject areas?

Hello,

I've just installed Unitime 4.4 on a new Win10-system. I've followed the provided manual.
While trying to login I'm getting following error: "Authentication failed: could not extract ResultSet"

What could be the cause?

THX

Salam,
I have achived a fresh unitime installation for testing and discovering the application functionalities, but once i'v deployed my application i would not log inside.
I have deployed unitime 4.4 build130.
My server is a tomcat 8 runing on a Zulu Jdk 8, with mariadb database and mysqlJ everything well setted.

when i try to log in using username and password : admin/admin or anything else(curicculum, exam, event) it does not work, and i do not receive any error message on the login page.

i have regenerated the password using :
java -cp unitime/solver/timetable.jar org.unitime.timetable.authenticate.jaas.DbAuthenticateModule admin
ISMvKXpXpadDiUoOSoAfww==
And iserted it in my users table.
the image attached bellow show the catalina.log properties who not report any authentication error, same as the login page.

Please if some one have faced the same issue, i will be thankful to have some advise.

Thanks.

I tested Unitime on two version 4.2 and 4.3. Both version are occurred an error when i add or edit Configuration for Courses at Instructional Offering.
The error is : "Configuration could not be updated. If possible, split your configuration change into 2 or more separate operations."
I deployed Unitime on a computer with Window 10.
I tried to do the same on your online demo, it worked ok.

I am getting the error below when trying to import a list of courses through the data exchange feature. Attached is the file I am trying to import.
Sample.txt

This feature was working fine in version 4.1, so it may be an issue with version 4.2. I am using the latest build "4.2.101 built on Sat, 11 Feb 2017"

Hello,

Since the upgrade to version 4.0, the Examination timetable grid disappeared/broke. Please check on it.

Attached, please find a screen shot for the whole page.

Timetable Grid returns nothing. The issue occurs only when Resource is selected as Curriculum even without any filtering. The page functionality works fine for other types. I have curricula already defined in UniTime. When committed I can access the curriculum schedules from the Events->Timetable page as intended.

Is it possible to have a distribution preference of either 'Back-To-Back on the same day' OR 'Different Days'?

When I try to view the Timetable Grid I get the message: Failed to load timetables:null. Although the Solver log does not show an error and I can export the table from the Saved Timetables to Excel. What could be reason?

I am getting the error below in Version 4.2.105 when opening an instructor detail page. The error only occurs when the instructor have a class assigned to them. The page works fine when there is no class assignment.
Best Regards

If anyone has faced a similar issue please let me know how to resolve it?

When the timetable show the classes for each subpart of the same course offering, each subpart is showed with a diferent color.
For us it could be very interesting that all the classes of the same course offering are printed with the same color. For the students is better for identificate all the classes (subparts) of the same course offering.
It could be possible to add a new parameter with values "true/false" like "Show all classes of the same course offering with the same color in the timetable?"

User registration (especially student) is needed for our use case where our automation software does not interface with UniTime.
UniTime letting users self register with captcha and password reminder functionality would help us #immensely.

By using XML how can i add datepattern and timepreference to the offerings?

END:VEVENT

You can see 1 hour and 50 minutes between the start and the end, and zero days. So it is an one day event, but it has to be repeated on friday and Saturday by RRULE. And it has even excluded dates after the end of the event.

Thank you.

when i set up unitime 4.4 ,running on my laptop ,but i find i can not find Instructor Scheduling Solver page and i can not find teaching request create and manage page .....
i login in by admin/admin .

any idea ? i am a new to unitime , looking forward to reply， thanks a lot!

Could you please help with our logic of scheduling of the courses.
We divided students by groups (Preparatory year is divided like two different groups 21 students are in one group A and 21 students in second group B). We need to schedule the courses by groups and then the system should show it in one line for group A and in second line group B. In an attached file I have example of the schedule which we want to have . Please guide how can we manage it.

When I try Load in Solver I get Error. What could be reason?

FATAL: Unable to load input data, reason: unexpected token: 0 near line 1, column 213 [select distinct i.externalUniqueId, a from org.unitime.timetable.model.ClassInstructor ci inner join ci.instructor i inner join ci.classInstructing.assignments a where ci.lead = true and i.externalUniqueId in (''08','19','18','17','16','15','14','11','19','10','18','17','16','15','10','14','11','06','09','08','08','07','06','09','05',''08','04','07','03','02','05','01','04','03','02','01') and a.solution.owner.session.uniqueId=:sessionId and a.solution.commited=true and a.solution.owner.uniqueId not in (5308416)] <<<

Hi,
I keep getting the error below when clicking the save button while editing or adding an exam in the course offering page. I got the error in a vanilla installation of version 4.1.77, 4.0.35 and 4.0.17.

Best Regards.

i cloned the repository and tried 'mvn package' and 'ant' and both failed with an 'EOFException' while 'compiling'

in my localhost I changed unitime.locale to ar and the pages not go from right to left and also tried localhost/login.jsp?locale=ar i got the same result

When you have defined an Academic Session an a Date Pattern and modify the start date of the session, automatically modify the date patterns class days.
Example

1. Create a session that starts on Monday September 7, 2015
2. Create a Date pattern and select the class days (weekly from Monday to Friday - 5 consecutive days)
3. Change the start date of the session to Tuesday 1 stiembre 2015
4. The Date patterns created modify the class days from Tuesday to Saturday (5 days consecutive but displaced from Tuesday).

Hey, Would you kindly add a confirmation alert when deleting a distribution preference.

Hello, I have recently installed/configured UniTime. When I load it in the browser, I am not getting the login screen, it's basically just blank.

It will be nice to add a "Same day" distribution type for Exams similar to what currently exist for courses.
Best Regards

Happy New Year!
Is it possible to link the Room Preferences drop down to Room Group Preferences such that when one selects "Classrooms" as "Required", only rooms meeting this criteria will show in the "Room Preferences" drop down?

Thanks.

Is it possible to import the required instructor attributes for each course through data exchange? If it’s not, it looks like an important feature that’s missing. There is an attributePref element described in the DTD of the interfaces, but it looks like it's not used anywhere:

/unitime-master/Documentation/Interfaces% cat Preferences.dtd | grep -i attr
<!ELEMENT attributePref EMPTY >
<!ATTLIST attributePref level ( R | -2 | -1 | 0 | 1 | 2 | P ) #REQUIRED >
<!ATTLIST attributePref attribute CDATA #REQUIRED >

I'm new with unitime and I'm using the page https://www.unitime.org/uct_interfaces.php to create the xml to import some data for testing.

Unfortunately, I'm having some issues, which i'd like to resolve:

1. When trying to import some courses, the number of rooms is always 0 and the only way to change it is through using the form of class configuration. How can I set the default number of Rooms to 1, without having to change it manually every time?

2. When creating the staff.xml to import instructors, is it normal not to see them automatically in the assigned department?

3. In the preferences.xml, is groupPreferences the name of the Room group that I have previously created?

Thank you for your support

Hi,

I am trying to work on UniTime but after installing I am getting the following error:

Errors occurred during the build.
Errors running builder 'Java Builder' on project 'UniTime'.
org.eclipse.jdt.internal.core.JavaProject.computePackageFragmentRoots([Lorg/eclipse/jdt/core/IClasspathEntry;ZLjava/util/Map;)[Lorg/eclipse/jdt/core/IPackageFragmentRoot;

Can anyone tell me how to resolve it?

I've been adding curricula all day. I was just about to go home, when I tried to save the last major I was working on and I get the following error.

Save failed: No row with the given identifier exists: [org.unitime.timetable.model.PosMajor#3407877]

It's as if the major or the academic area has been blown away. I have no idea what would have caused this.

The software is logging about a thousand times a day:
