运行时，提示类似这样的错误：Jar file could not be initialized
And, an exception: java.util.zip.ZipException: invalid entry compressed size (expected 552 but got 555 bytes)…
解决办法（来自forum nokia）：
Go to the properties page of your project, “J2ME”, “Manage Devices”, edit all or your favourite “Emulator” entries and remove the ‘[%classpath%|-classpath “%classpath%”]’ entry from the Launch Command Table.
