i keep on getting the following error when ever i try to run my code to check connection between java code and db.

There's not really enough information here to help you. Check out this question for a good example on how to pose your question, and possibly find an answer.
Its' showing No suitable driver found. Check your jdk compatible driver version with sql server.
Check system requirements here
Both jdk 7 and jdk 8 compatible jar file

Hi I am unable to connect to database from cmd, there is a problem in establishing a connection. I am using DB2 10.5 version client. Databse is on 10.5 server (Triend with db on 9.7 version server too).
I get the below excpetion :

Please help on resolving the issue.
Have a look at the manual entry for this error message.
It may be that your database configuration needs to be upgraded.
Explanation
A system error occurred. Some possible reasons for this error are:
The database manager is not installed correctly or the environment is not set up correctly.
On UNIX-based systems, db2iupdt may need to be run in order to update the DB2 instance to enable acquisition of a new system
configuration or access to function associated with the installation
or removal of certain product options, FixPaks, or modification
levels.
You might get this message if you are not using the correct DB2 Administration Server password.
There is more information about the error at the page I linked above.
You should check the contents of the DB2 diagnostics log file (db2diag.log) on the server side. The JDBC driver itself usually does not raise errors of such type, so there must be something wrong on the server.
For me the following helped: make sure you set the driver type 4.
db2datasource.setDriverType(4);
// put driverType=4; into the jdbc url

I have two versions of java, one is 1.8.0_25, the other is 1.7.0_46
this is my path
C:\Program Files (x86)\Java\jre7\bin;;C:\oraclexe\app\oracle\product\11.2.0\server\bin;;C:\ProgramData\Oracle\Java\javapath;
and as a default I use the jre7 on eclipse, dont know what else to mention here. I found no solutions clearly explained here or on the other websites rather than trying to change the java version, tried all java instances on my computer, uninstalled and installed again. I am guessing it may be about java and datanucleus compability issue, but currently using the java7 and the plugins i am using were downloaded automatically from eclipse so no clue. If you need any clarifications, ask me out please.
If you are using Java 8, you need to set the compiler compliance level to 1.7 in project properties. You will also need to change the java facet version
Note that (GoogleAppEngine Enhancer Error Code 1:)
App Engine doesn't work with Java 1.8. Try doing it again, with Java 1.7
Setting Java 1.7 in Project settings solves me the problem.
Well like I have guessed, it is all about the compatibility issue. If you are getting this error, make sure EVERYTHING your eclipse AND your computer use is the same version of java everywhere. What I mean is you need to check;
In eclipse, from the top menu choose Project->Properties, then make sure all the versions of java used by eclipse are the same.
AND
AND
and of course your environment variable should point to the same version that eclipse uses.
Hope this helps. Post comments if you found it unclear. Getting errors before even started coding sucks :p

Thanks for help.
This is a bug in this version of the database engine, which was fixed in revision 5437 of the trunk.
You can either:
go back to the previous version (1.3.174) which should not have this bug,
use the latest nightly build where it should be fixed,
download the latest source code and built the database yourself, or
wait for the next version of H2.
For those who are willing to read a bit, (skip to end for short version):
I am trying to connect my java app to a remote oracle database. with no luck I am using Mac 10.7.5 with IntelliJ Idea 12, java version "1.6.0_51" 64-bit. I have been trying to get this work all day with no success. I also was not able to use the 'DataSource' view in IntelliJ because of a missing shared dylib missing in java.library.path. I suspect the two issues are related.
I tried installing Oracle Instant Client 64-bit (including the jdbc files), copied the dylibs to /usr/lib/java and this got me close to solving the "DataSource" view issue with a different error:
java.lang.RuntimeException: java.rmi.UnmarshalException: Error unmarshaling return header; nested exception is:

So the journey continued and I tried using the 32bit version of the ojdbc .dylibs and .jars but then I ran into 'wrong architecture'when trying to connect to oracle db using IntelliJ's DataSource view.
I would like to keep everything consistent by using 32-bit since most of my apps use libraries that require 32-bit JVM.
tl;dr 'ers:
-Cannot connect to oracle db through IntelliJ Idea 12 DataSource view nor connect through java app using JDBC
-BackGround Info: Mac OSX 10.7.5, Java 1.6.0_51 64-bit, IntelliJ Idea 12, Remote Oracle 11G DB
-Tried both 32-bit and 64-bit versions of Oracle Instant Client with jdbc files, no luck
Any suggestions will be greatly appreciated!
Thank you
Additional Notes: I cannot connect through sqlplus either; i get the error ORA-21561: OID generation failed. Search results only point to fixing the /etc/hosts file which does not make sense for me since the db server is on a remote server and I am connecting using a TNS entry in /etc/tnsnames.ora
===UPDATE 1===
I made some progress on connecting through the java code. Using this code:
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:#hostname:port/service_name", "user", "password");
but received the error:
java.sql.SQLRecoverableException: IO Error: The Network Adapter could not establish the connection
I CAN connect using this exact piece of code on my work machine through eclipse ide but not on my Mac laptop.
For Intellij/DataGrip 2018 DB connection via TNS I got
[08006][17002] IO Error: Invalid connection string format, a valid format is: "host:port:sid"
I find the problem in Oracle driver version: 11.2.0.4
I get "Test Connection > Succesful" using version 12.1.0.2
I can only encourage you to use the oracle thin jdbc client. There must be a very specific reason not to. With that you will likely have NO problems.
I am using windows server 2003 on VM vare on which I have my database on MS SQL Server 2008 . Now when I used jdbc driver to connect my java code with database I am getting following exception. Kindly give some solution .

You have enabled integratedSecurity. This means that the sqljdbc_auth.dll needs to be on the library path of the jvm.
Most likely you do not have this library on your path, it is the wrong version or the wrong variant (x86 <> x64 <> IA64).
An old question but I had this issue today. I don't know the first thing about Java but for me the fix was to copy Microsoft's JDBC driver to Java's ext folder.
sqljdbc41.jar needs to be copied to C:\[path to java installation]\Java\jre7\lib\ext\
Make sure you pick the right version (x86 or x64).
Also for Integrated Security I needed to make a reference to auth when starting my application.
-Djava.library.path=C:\[Path to Microsoft JDBC Driver 4.1 for SQLServer]\sqljdbc_4.1\enu\auth\x86
I had the same exception when starting SpringBatch with an JdbcBatchItemWriter writing to MS SQL Server 2008.
Sqljdbc_auth.dll was on the library path. It turned out that I was running my SpringBatch application in Eclipse with JRE 1.6. I solved this by running it with JRE 1.7 (Eclipse JRE-Tab in Run-Configurations).
