Re: Login to activiti-explorer and activiti-probe problem

frederikherema1 — Fri, 10 Dec 2010 18:05:42 GMT

Are you using the default demo running on H2? Seems like postgres-specific statements are used on a H2 database, strange.

What does your build.properties look like?


### The error may exist in org/activiti/db/ibatis/variable.mapping.xml
### The error occurred while processing mapper_resultMap[byteArrayResultMap_post
gres]
### Cause: org.h2.jdbc.JdbcSQLException: Polaczenie uszkodzone: "session closed"

Re: Login to activiti-explorer and activiti-probe problem

jcosano — Mon, 13 Dec 2010 11:50:38 GMT

I have the same problem.

I install activiti first with h2 database.

After, i change to mysql, and run cfg.create and I put my new cfg file into tomcat lib.

Then, first time that I start explorer show this error… after a while all begin to work fine… but first time the error is showed!

Re: Login to activiti-explorer and activiti-probe problem

frederikherema1 — Mon, 13 Dec 2010 11:58:50 GMT

After you have altered the database config, you should run the demo.install again (and possibly demo.stop) to get the right libs copied to tomcat, based on your DB-config.

Alternative is to copy the required libs for the DB yourself (all of these can be found in de distro /setup/files/dependencies/libs/ folder, except for oracle JDBC-driver)

Re: Login to activiti-explorer and activiti-probe problem

jcosano — Mon, 13 Dec 2010 12:10:28 GMT

I copy all but initial error persists.

Error is showed only first time that I try to login, error is show, but after a seconds, login is complete, and all begin to work fine… (logout and login works, and error is not show)

Re: Login to activiti-explorer and activiti-probe problem

frederikherema1 — Mon, 13 Dec 2010 12:15:08 GMT

Woops,

I meant that the new config should be present (activiti.cfg.xml) on the tomcat's classpatch, not the DB-drivers

Re: Login to activiti-explorer and activiti-probe problem

jcosano — Mon, 13 Dec 2010 12:22:08 GMT

My activiti-cfg.jar is in tomcat lib too! and with mysql

Re: Login to activiti-explorer and activiti-probe problem

jcosano — Mon, 13 Dec 2010 12:57:47 GMT

I do:

ant demo.clean
ant cfg.create
ant demo.start

and problem solve!

Hi I am also facing the same problem using activiti 5.2 configured with mysql. I got rid of the H2 error by replacing activiti-cfg.xml in ../kickstart/WEB-INF/lib with the newly created activiti-cfg.xml containing my mysql config as the one with the H2 config was not replaced during setup. So I no longer have any errors my server logs but still I am getting the message:

The system was unable to log you in. in the browser and Connection refused: connect in the server logs. I suspect this has something to do with connection to MySQL (using MySQL 5.1.2). I have tried to replace the mysql-connector-java-5.0.4-bin that ships with activiti-5.2 with mysql-connector-java-5.0.7-bin to no avail.

Any thoughts anyone?

Regards,

Okay so now I've tried creating another instance using Postgresql as the server this time around. Even with my Windows Firewall disabled the same issue is persisting. I can only view the http://localhost:8383/activiti-kickstart and http://localhost:8383/activiti-modeler. All the other resources with login pages throw the errors described above.

Which exception is that, because the only exception I see in this thread is a H2 error?

I see that you are running on another port than the default one. Did you change the port of the webapps (doesnt work automatically if you change ports)?

Re: Login to activiti-explorer and activiti-probe problem

chibsta — Mon, 07 Mar 2011 10:56:53 GMT

Thanks jbarrez. That was it! As soon as I changed the port back to the default 8080, no more problems. how do I change the port for the apps?

if anyone is getting "H2 : session closed" exception while running : "http://activiti.org/userguide/index.html#10minutetutorial"

then first start your H2 database and try again.
"D:\Program Files\activiti-5.9\setup>ant h2.start"

This solved my problem.

Thanks.

Does your ACT_ID_USER table contains users? Did you remove the DemoDataGenerator from the explorer config?
