I am using Eclipse Juno and Jre7. I'm also using Java ME SDK 3.0 and I have tried Java ME 8.1 too.

I have all the JAR files I need. The project works in a normal Java Project. But midlet project is creating the problem. So, the problem is not with the JRE or eclipse. It has something to do with midlet project. Could anyone tell me what could be the reason ? Is there a way to remove these errors ?

This is the error:

java.lang.String Error preverifying class java.lang.String

Are you using an Eclipse plugin? Which one? – Telmo Pimentel Mota Sep 11 '15 at 20:00
No. I'm not using an eclipse plug in. Using JAVA ME(Micro edition) – Nivedita Velagaleti Sep 14 '15 at 15:56
Java code compiled by Eclipse will create class files based on JRE. Java ME SDK will deny these class files. Have you tried Antenna? – Telmo Pimentel Mota Sep 14 '15 at 16:58

^ this is the exception I am encountering after build of J2ME application. I have no clue what is going on? The classes have built properly and packaged in a jar. – Nivedita Velagaleti Sep 14 '15 at 19:49
Your question was about a preverification issue. Now you add a comment about a NullPointerException... Did you preverification error stop? – Telmo Pimentel Mota Sep 15 '15 at 11:30
Yes, When I used the proguard preverification settings, it builds without errors but at run time gives an exception. – Nivedita Velagaleti Sep 15 '15 at 12:53
So... your original question is not necessary, please, delete it. – Telmo Pimentel Mota Sep 15 '15 at 16:50
