J2ME support?

Aspose.Words Product Family
#1

Hi,

I would like to know if Aspose.Words would run on a J2ME platform, which has only 32 Mbytes memory and consist of a subset of J2SE 1.4.

In details the platform consists of:

• Connected Device Configuration 1.1

• Foundation Profile 1.1

• Personal Profile 1.1

• RMI Optional Package 1.0

And include the following packages :

• java.applet • java.rmi.activation

• java.awt • java.rmi.dgc

• java.awt.color • java.rmi.registry

• java.awt.datatransfer • java.rmi.server

• java.awt.event • java.security

• java.awt.font • java.security.acl

• java.awt.im • java.security.cert

• java.awt.image • java.security.interfaces

• java.beans • java.security.spec

• java.io • java.text

• java.lang • java.util

• java.lang.ref • java.util.jar

• java.lang.reflect • java.util.zip

• java.math • javax.microedition.io

• java.net • javax.microedition.xlet

• java.rmi • javax.microedition.xlet.ixc

Thank you very much for your help,

Ben

Hi, Ben,<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

It is very interesting question. We never target Aspose.Words on Micro Edition yet, but…

  1. Aspose.Words is small: jar for jdk1.5 is 1.06M, jar for jdk1.4 is 1.129M.
  2. Aspose.Words is developed with high performance and small memory footprint in mind.
  3. Aspose.Words bytecode heavily shrinked, obfuscated and optimized – so you can use Aspose.Words jar in mobile environment as is, without additional optimization.
  4. Since v.2.4.1 (will be published today) all external libraries obfuscated into Aspose.Words jar – so you don’t need in additional libraries.

All this optimizations targeted server environment but can be useful in mobile environment as well. I think several problems can arise in mobile environment:

  1. Aspose.Words heavily uses core java SE api – some core SE packages can absent in your environment.
  2. Aspose.Words assumes that host computer (probably server) has mach more memory than 32M. It doesn’t use any disk-swapping or other techniques to limit memory using to the some special value. So, a long document, especially with pictures, especially with some picture formats that internally converted (by-default) to another format – can cause insufficient memory errors.

Afraid I don’t strong in J2ME and particularly in modern Sun CDC toolkit which you using – it’s seems that Sun tied it solely to NetBeans and my IntelliJ IDEA don’t recognize it as a J2ME SDK. Please, wait a little and try new Aspose.Words 2.4.1 jar in your environment, - you need only two lines for very first test (plus import statement for com.aspose.words.Document):

Document doc = new Document();

doc.save(“TestDoc.doc”);

Please, inform me about results, it’s very interesting:)

Best Regards,

Hi, Ben,<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

We released self-contained jar that don’t need in external libraries (I speak about it in previous mail). You can get it from http://www.aspose.com/Community/files/51/aspose.words/entry115338.aspx .
