Crystal Report error - connection with Oracle using Java

I'm migrating from Crystal report 2012 to 2020 and connecting crystal report 2020 with an oracle 19c, but when i try to connect my application (using Java) with Crystal Report Java gives me an error. Specifically:
Connection error: The oracle url is not valid
but in the logs I saw that is using the correct url
Connection logon:Database DLL=s(crdb_jdbc.dll);Use JDBC=b(true);Connection URL=s(jdbc:oracle:thin:{userid}/{password}#serverName:1521:dataBaseSID);Database Class Name=s(oracle.jdbc.driver.OracleDriver);Server=s(serverName);Trusted_Connection=b(false);JDBC Connection String=s(!oracle.jdbc.driver.OracleDriver!jdbc:oracle:thin:{userid}/{password}#serverName:1521:dataBaseSID);PreQEServerName=s(jdbc:oracle:thin:{userid}/{password}#serverName:1521:dataBaseSID);database=s();User ID=s(testUserDB);Password=
I tried many url configurations like
jdbc:oracle:thin:{userid}/{password}#//serverName:1521/dataBaseServices
jdbc:oracle:thin:#serverName:1521:dataBaseSID
jdbc:oracle:thin:#//serverName:1521:dataBaseSID
jdbc:oracle:thin:#serverName:1521/dataBaseServices
jdbc:oracle:thin:#//serverName:1521/dataBaseServices
but none of these work, and I don't know what is causing the error.
The curious part is that if I try any of those urls with, with crystal report 2020, they work perfectly - but with java I receive the url error.
I also try to change the class name from oracle.jdbc.driver.OracleDriver to oracle.jdbc.OracleDriver but without lucky.
the line that is giving the error is:
reportClientDocument.getDatabaseController().logon("testUserDB", "passwordBD");
the class report client document use this library com.crystaldecisions.reports.sdk.ReportClientDocument; I tried to change that library for com.crystaldecisions.sdk.occa.report.application.ReportClientDocument and I had the same error.
I'm using Spring Tool Suite 4 as IDE that is base on eclipse 4.15.0, JDK 1.8 and ojdbc8 (connector to oracle 19c)
I already downloaded the libraries, features and plugins of Crystal Reports for Eclipse SP27 and installed in my environment and even with that, |I still have the same problem.

See the following post: Java JDBC - How to connect to Oracle using Service Name instead of SID
The correct format you should use is the following:
jdbc:oracle:thin:#//<host>:<port>/<service>
So, for example:
jdbc:oracle:thin:scott/tiger#//myhost:1521/myservicename
jdbc:oracle:thin:userId/Password#//servername:1521/dataBaseService
You could also try the TNS format:
jdbc:oracle:thin:#(description=(address=(host=HOSTNAME)(protocol=tcp)(port=PORT))(connect_data=(service_name=SERVICENAME)(server=SHARED)))

Error linking JNA library on AdoptOpenJDK on MacOS

I am trying to run some JUnit tests over cassandra. But I get the following error:

It was running well until I changed to mac mojave and re-setup everything. I think it is an issue related to permissions may be or JNA?
IDE: IntelliJ
Java: AdoptOpenJDK 11.0.4
JNA: 4.2.2
Any kind of help will be highly appreciated!

This is the result of a bug in AdoptOpenJDK jdk-11.0.4+11 on macOS, persisting through 11.2.
It will be fixed in the jdk-11.0.4+11.3 release.
If you can't wait for the new release you can temporarily resolve by downgrading to 11.0.3+7

What version of cassandra unit? Support for java 11 (https://issues.apache.org/jira/browse/CASSANDRA-9608) isn't in until cassandra 4 and I dont think embedded cassandra is setup for that yet

Structr - which version of Neo4j to use

Windows 7, java 8, Neo4j 3.0.0-M03, initial install of structr.
When I first try to run the program I'm getting this error:
SEVERE: Vital service HttpService failed to start: No resource provider available for servlet JsonRestServlet. Aborting
Reading the Google Groups the report is that structr is only good up to 2.2.6 - looking at the Neo4j Release Page 2.2.6 has been skipped - it goes from 2.1.8 to 2.2.8.
My question is what version should I use?
Also - is java 7 still a requirement? Looking at the Oracle website I'm seeing that 7 has been deprecated and won't be patched.

The most recent pre-built versions of Structr are built against and embed Neo4j 2.2.8.
To use with custom Neo4j versions, you can to build your own driver, see https://github.com/structr/structr-neo4j-driver. Should work with any 2.x version of Neo4j.
On the Java side, Java JDK 8 is a requirement.

I'm attempting to deploy a google app to my google app engine account and eclipse is giving me this error. It seems rather straight forward, but I can't find where to set a flag for java7.
I'm using the latest version of Eclipse (Juno Service Release 1) and my google plugin is 4.2.

The relevant system level property is shown here: com.google.apphosting.runtime.use_java7
It can be passed into appCfg.sh like so:
appcfg.sh --use_java7 update

As per the 1.7.3 blog post:
In an upcoming release, we will be including some of the new Java 7
functionality as well as formal Java 7 support within the App Engine
Java runtime.
and...
And while Java 7 support is not yet available within the App Engine
Java runtime, developers interested in an early preview can sign up
for our trusted tester program.
You'll need to either be accepted into the TT program, or to wait for a future release where Java 7 works in production.

Liquibase, "Migration Failed: Java heap space" error when generateChangeLog with "data"

I am trying to create a baseline on one of my development database using liquibase, here's my environment
- Database, -> Oralce 10g, with 500+ Tables with lots of configuration data, the oracle export dump file is about 70mb;
- Java - Java 6
- Oracle JDBC Driver - ojdbc14.jar (downloaded from Oracle web site)
- Command line execute
liquibase --changeLogFile=base.changelog.data.xml --diffTypes="data" generateChangeLog
Execute result:
- Liquibase is configure to run with "-Xmx512m -Xms256m" jvm parameters, fail, error message - "Migration Failed: Java heap space
"
- configure to run with "-Xmx1024m -Xms512m", same error occurs
- configure to run with "-Xmx2048 -Xms512m", same error
What other options I have in oder to create base line for my development projects, so that we could start version control our db..
Appreciate ur advise, thanks!
James

Which version of liquibase are you using? There has been some improvements in the performance of the diff support in the upcoming 2.0. The latest build can be gotten from http://liquibase.org/ci/latest (once the bamboo server is fully upgraded)
