Question

I am having trouble installing the ME platform for Netbeans 8.0 - I have:

• Installed Netbeans IDE 8.0

• Installed jmesdk-3.4

• Installed the jmesdk-3.4 plugin & activated it in Netbeans

When I try to create a New Java ME > Mobile application project I get a warning saying

No Java ME Platform found. Please add at least one

When i try to add the java platform by locating the jmesdk-3.4 folder, it tells me no platform was detected automatically(failed) and it requires me to add manually.But adding it manually just creates more confusion. need help please.

Answer 2

I did what the other answer recommends, which worked, but only when using Netbeans IDE 7.4 and JDK 1.7 for a 32-bit system ( https://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase7-521261.html ). Currently using a Windows 10 64-bit system. Note that I did not accept any updates for the required Java ME plugins, as I hear that might make things crash.

Answer 3

I heve readed that that can be being caused by the new serialization filter feature in the JDK( Serialization Filtering . Seems that it was added to JDK 8 after the 112 update so on this update of the JDK it shall work but it certainly is possibly to use the Java ME SDK on JDKs with this feature. I did it at least on JDK 1.8.0_192. To this I had to make some changes on the java.security file. The chages were:

• Remove the # on front of jdk.serialFilter
• Replace the texto after jdk.serialFilter to *
• Romove the # on front of sun.rmi.registry.registryFilter property and of it parametres and remove the whitespaces and / from the same.
• Do the same on the sun.rmi.transport.dgcFilter property.
• Append ;* at the last parameter of sun.rmi.registry.registryFilter

It seems to be importante to not corrupt the parameters because I do this and the emulator wasn't starting.

I tried on JDK 11.0.1 and it don't work.
