I’m now trying to install and run some Java midlet applications on Dopod 900 with Windows Mobile Operating System. I found that Dopod 900 has included a Midlet Manager that manage the installation and execution of the midlets in this gadget.
I have no such difficulties to install the midlets as the .jar files will be recognized and then then automatically installed to the gadget when I open them.
But I found that several midlets I have created before were failed to be installed with “Invalid jar file” error when I try to open it. Unfortunately.. They run normally on various cellphone.
I tried over and over, looked for some potential solutions from internet. I thought that it was the JVM that I used was not compatible with the JVM installed on the PocketPC. So, I installed the other JDK and re-compile the midlet. But, it did’nt solve the problem.. :-(
Desperately, I looked for other solutions. It is said that might be the icon file caused the error. So, I added the icon image into the midlet (I wasn’t added the icon image in several midlets before). When I re-compiled and got the .jar file, I transferred it into to the gadget. Then I opened it and, blink! It works…(thanks god)
I didn’t know that the icon file will cause an fatal-headache- error like that. |
