Problem to install signed j2me app to S40. S60works fine

[teamforce_paul]

Hi I have j2me app signed with Thawte cert. It works fine on S60 devices, but not on Nokia 5310.
Any ideas?
Thank you.

Does this help? If not, what is the exact error message in English?

Thank you for your post.
Let me try to check. I'll let you know.
Exact error message -
once I try to install the app (Click on JAR file)
it shows me "wrong application Delete?"

The reason why I decided it is certificate issue, because unsigned app works fine.

Thank you

Hi guys,
I solved the problem.
Just want to post solution if it might be helpful for someone.
The problem was:
I signed application and modified BOTH JAD and JAR.
I mean in addition to JAD changes:
MIDlet-Certificate-1-1
MIDlet-Certificate-1-2
MIDlet-Certificate-1-3
MIDlet-Jar-RSA-SHA1

JAR was signed also:
certificate.rsa
sertificate.sf
were added to META-INF directory
and
manifest.mf was changed
For example following was added:

Name: aq.class
SHA1-Digest: +QosnhrLxlh/IZIT8UqF88aOAZI=

Name: logo.png
SHA1-Digest: Xlixm2wZS9FqPwm0bEsTpPpBbd0=

Name: aa.class
SHA1-Digest: wiCL3YWV/cT+CC3y2VcHjSYbZ5o=

It works on S60, but not on S40.
Just keep JAR unmodified it is not needed on J2me platform.

Thank you everyone,
who read the post.
