Java.lang.ClassNotFoundException: net.sourceforge.jtds.jdbc.Driver On Android

Question

Today I am doing Connectivity of SqlServer using JTDS driver. But when I run program I found Below error

Java.lang.ClassNotFoundException: net.sourceforge.jtds.jdbc.Driver
Caused by: java.lang.ClassNotFoundException: net.sourceforge.jtds.jdbc.Driver in loader dalvik.system.PathClassLoader[/data/app/com.kmkm.lll-2.apk]

I already search on this topic and I found answer as

java -classpath .:jtds.jar MyApp 

but I am confuse how and where I run this command? Why this error comes?

Answer 1

I had the same problem with my Android app in Eclipse. What worked for me was to export the external jars with my app.

If you have already added the jtds-1.2.5 driver, good. Otherwise:

Right click on the Project > Properties > Libraries Tab Add the jtds-1.2.5.jar file by clicking on "Add External JARs"

Next, in the Order and Export tab (Right next to Libraries in the Java Build Path window) check the box for jtds-1.2.5.jar (and any other external jars you might have).

This will export the .jar containing the driver with the .apk file.

Answer 2

If you are using eclipse, Try this steps

• Right click on your project
• Click Build Path > Configure Build Path...
• Choose Libraries tag and click Add External JARs...
• Point your jtds.jar and click OK.
• Rebuild and run again.

If you use a third party library, make sure you have all its required dependencies, if it requires any.
