How To Solve Java.Lang.Unsatisfiedlinkerror: No Ocijdbc11 Inwards Java
"java.lang.unsatisfiedlinkerror no ocijdbc11 inwards java.library.path" mistake comes when you lot seek to connect to Oracle 11g database using OCI (thick) driver past times using tns name, but the ocijdbc11.dll file is non available inwards PATH or java.library.path environs variable. ocijdbc11.dll is a native library in addition to if you lot know Java searches native library inwards PATH or a place specified past times java.library.path system property, if it doesn't notice the dll, thence it throws java.lang.unsatisfiedlinkerror no ocijdbc11 inwards java.library.path error. This dll is ordinarily constitute inwards C:\Programs\Oracle\ora11g\bin\ocijdbc11.dll, but it could vary depending upon your Oracle installation.
The commencement measuring to solving this mistake is a search for this dll inwards your machine, if you lot are using windows, simply search inwards your C drive. If the dll is non at that spot thence you lot postulate to download that from Oracle's website. If it's already introduce thence simply add together its place into PATH variable.
If you lot are explicitly providing java.library.path thence also render it at that spot e.g.
-Djava.library.path=C:\Programs\Oracle\ora11g\bin\ocijdbc11.dll . By the way, if you lot really desire to larn Java database programming from scratch, I advise you lot receive got a await at Practical database programming amongst Java book past times Ying Bai. This majority explains every of import item of Java database connectivity.
By the way, this is non the criterion way to connect to Oracle database from Java. Oracle users mainly purpose OCI driver for OS authentication or if they don't know the IP address of the server in addition to desire to connect using TNSE, but if you lot are non concerned of that, you lot tin laissez passer on the axe ever purpose Oracle JDBC sparse driver to connect. For that, you lot simply postulate to include ojdbc.jar inwards your classpath.
Just scream upwardly if you lot purpose an OCI URL e.g. "jdbc:oracle:oci:/@"+tnsName thence you lot are using thick driver in addition to you lot postulate oracle customer libraries on the PATH, for that you lot postulate Oracle customer to hold out installed on your machine, but if you lot purpose sparse driver amongst next URL format "jdbc:oracle:thin:@"+dbServer+":"+port+":"+SID; you lot simply postulate driver's JAR file in addition to no native library volition hold out required because its type four pure Java driver.
Btw, this is optional if you lot don't render this organization belongings Java volition await on all folders included inwards PATH environs variable.
If you lot don't notice this dll file thence you lot postulate to install Oracle customer to acquire this dll. If you lot install Oracle 11g inwards 64-bit Windows vii machine thence this native library tin laissez passer on the axe hold out constitute inwards C:\Programs\Oracle\ora11g\bin\ocijdbc11.dll folder. Now simply add together this folder to your PATH in addition to run your plan again, provided whatever other mistake you lot should hold out able to connect to Oracle server.
The instant solution is to use Oracle JDBC sparse driver to connect Oracle database. For this you lot postulate to alter your JDBC URL format equally "jdbc:oracle:thin:@"+dbServer+":"+port+":"+SID; in addition to include ojdbc6.jar inwards to your CLASSPATH.
Always scream upwardly the departure betwixt PATH in addition to CLASSPATH, PATH is used to locate executable files, native library files but JAR is ever loaded from the classpath. This is also the criterion way to connect to Oracle 11g database.
You tin laissez passer on the axe also run across Core Java Volume II - Advanced Features past times Cay S. Horstmann to larn to a greater extent than nearly database programming inwards Java using JDBC. One of the consummate majority to larn Java.
For the thick driver, you lot postulate ocijdbc11.dll inwards your PATH in addition to for the sparse driver, you lot postulate ojdbc6.jar or ojdbc6_g.jar, afterward ane is a debug version. So if you lot acquire this mistake piece using SQL Developer, follow the higher upwardly measuring to form it out.
If you lot are using Oracle 10g thence you lot volition probable to run across java.lang.unsatisfiedlinkerror no ocijdbc10 inwards java.library.path, the solution is same notice the dll in addition to add together into PATH. Also, ojdbc6.jar tin laissez passer on the axe hold out constitute inwards C:\Programs\Oracle\ora11g\jdbc\lib\ location, where ORACLE_HOME.
Since this is also a type of java.lang.unsatisfiedlinkerror, you lot tin laissez passer on the axe also run across this tutorial to acquire a full general persuasion nearly how to solve this mistake inwards Java. You volition probable to run across this type of mistake whenever your Java plan volition purpose native libraries, either internal or external to produce stuff.
That's all nearly how to fix java.lang.unsatisfiedlinkerror no ocijdbc11 inwards java.library.path mistake in Java. You acquire this mistake when you lot seek to connect to an Oracle 11g database from Java plan past times using its TNS cite in addition to non the IP address. You tin laissez passer on the axe ready this mistake past times adding ocijdbc11.dll inwards your PATH environs variable or into your java.library.path variable.
If that DLL is non available inwards your organization thence download in addition to install Oracle customer similar SQL Developer, which contains both thick in addition to sparse JDBC driver to connect to Oracle database.
If you lot get java.lang.unsatisfiedlinkerror no ocijdbc10 inwards java.library.path agency you lot are connecting to Oracle 10g database but the solution is same amongst the exclusively departure inwards Oracle version difference. Let us know if you lot confront whatever final result piece connecting to Oracle database from Java in addition to I volition seek to aid you lot here.

The commencement measuring to solving this mistake is a search for this dll inwards your machine, if you lot are using windows, simply search inwards your C drive. If the dll is non at that spot thence you lot postulate to download that from Oracle's website. If it's already introduce thence simply add together its place into PATH variable.
If you lot are explicitly providing java.library.path thence also render it at that spot e.g.
-Djava.library.path=C:\Programs\Oracle\ora11g\bin\ocijdbc11.dll . By the way, if you lot really desire to larn Java database programming from scratch, I advise you lot receive got a await at Practical database programming amongst Java book past times Ying Bai.
