I am trying to download the jvm but I can't.

In the list of supported units the T5 is absent and when I choose "other unit" it says that my unit does not support Web Sphere...

Go to and use your Palm OS developer login to get both the simulator build and the device-specific build for current palmOne devices.

What's the point?

Wolfgard @ 2/1/2005 2:39:23 PM # Q
Nobody writes Java programs for PalmOS, so why install the virtual machine?

What about online content?
Are we talking the same Java here?

RE: What's the point?
Wolfgard @ 2/1/2005 2:59:06 PM # Q
No, not java as in java applets/servlets. I mean java applications like those used in Symbian devices (J2ME applications).

Java and JVM's may not be as popular for end-user apps, but many corporate in-house and vertical/enterprise developers like to develop and port their apps this way.

Java doesn't have much of a retail future in my opinion. However, IT guys will love this for their applets to be ported in only a week.

@RhinoSteve - Java doesn't have much of a retail future in my opinion

That's not true. Java is very popular especially in enterprise softwares and internet programming. Plus, it's highly portable thanks to JVM and is a much more elegant object oriented languange compared to Microsoft's .NET languages. The only reason why most people don't see java programs is because they usually run on Linux/Unix systems or are used in big corporations. Hopefully with PalmOS Linux coming, Java will make big strides in the handheld arena (just like it did in smartphones/Symbian).

I bought some Texas Hold'em software 3 weeks ago. Much to my disappointment I needed that Java software that we are talking about which wasn't available and still isn't available. I'm not that addicted to gambling but I want to use something I paid for. sigh.

No T3?

sremick @ 2/1/2005 3:20:02 PM # Q
And this isn't available for the T3 because....?

What? Those extra 16MHz make THAT much difference?

I actually had Java working on my T3. I used the developer utilities to convert a bunch of utilities and games over.

Unfortunately, most the cool Java stuff is developed for specific model phones. Which makes you wonder why they write in Java at all, if it can't be ported to anything else other than a Nokia model 123 or whatever.

Still, I don't get what makes the T5 able to use this and the T3 unable. In many regards, the T3 is faster than the T5 due to the different memory.

Wolfgard @ 2/1/2005 3:27:26 PM # Q
On contrary to what most people believe, Java is not 100% 'write-once,run-anywhere'. Only basic codes work that way (and is interpreted by different virtual machines). Once developers dig into complex APIs and stuffs, it's not longer portable just by recompilation. However, a well designed Java program should be easily ported if the engineers adhere to strict software design rules.

It's got nothing to do with the processor, you can be sure of that. I run Java apps very nicely in old 16MHz Handspring Visors.

Perhaps palmOne would rather be selling T5s and Treo 650s to the businesses for which Java support is an important feature. Some say the T3 is on its way out, right?

Mobile Java is becoming much more important

cervezas @ 2/1/2005 6:48:37 PM # Q
What needs to be appreciated is that it's a lot easier to sell businesses on custom mobile software written in Java than the Palm OS C API. Java applications are faster to develop and easier to maintain. For most business applications the hit in performance is not important.

Personally, I think PalmSource would do well to get behind SuperWaba and put that VM in ROM. It's smaller, faster, and has a richer graphical user interface than J2ME MIDP. With SuperWaba 5.0 (just released) applications *can* be written once and deployed on Palm OS, Windows Mobile, and Symbian smart phones. You can even run them with full functionality in a web page because the code will execute in a regular JVM. Great for demos!

Palm just needed to get off their butts and support J2ME CDC Personal Profile. It's available on the other major PDA platforms. It was designed for PDAs and similar devices.

I'm becoming conviced that Palm has relegated themselves to the smartphone world with this MIDP only plan. I love Java, but I want to write MIDlets for the Palm like I want a hole in the head.

YAWN, I need to save these Java-Palm posts somewhere. It's not like people haven't been repeating this same thing for 2+ years.

Still not available....

vesther @ 2/3/2005 6:48:41 PM # Q
Dunno why...but I don't see the link for the Version 5.7 for current Athena Handhelds (palmOne Tungsten T5 and Treo 650) on the palmOne JVM Download Page. I think palmOne needs to do some final bug-fixing IMO.

How one can watch 3GPvideo clip on Palm T5, which video player is suitable to play this clip?

The link is now working and available for download

Downloaded that Java Engine onto my Tungsten T5--I currently have no problems running the WebSphere Everywhere program on my Tungsten T5.

Here are the supported devices:

* Zire 72 (Free)
* Tungsten T5 (Free)
* Treo 650 (Free)
* Treo 600 (Must pay to use it)
* Tungsten C (Must pay to use it)
* Tungsten T3 (Must pay to use it)
* Tungsten E (Must pay to use it)

The Tungsten T, Tungsten T2, Tungsten W, Zire 21, Zire 31, and Zire 72 handhelds are left in the dark. Why?! Java is extremely important for a palmOne handheld IMO. I don't see why palmOne has to put handheld users of the following handhelds in the dark...
