Use OTA to download the local j2_program to the mobile phone
Environment: windows2000 + tomcat4.1.24 + j2wtk2.0
1. Install a web server and use tomcat. Modify the corresponding configuration file to support the JAD and jar mime types.
Type
JAD: text/vnd. sun. J2EE. app-descriptor
JAR: application/java-archive
Do not tell me If TOMCAT is installed ?), The new version of tomcat is supported by default. in earlier versions, modify % tocmat %/conf/web. xml to find the mime and add it.
- <mime-mapping>
- <extension>jad</extension>
- <mime-type>text/vnd.sun.J2ME.app-descriptor</mime-type>
- </mime-mapping>
- <mime-mapping>
- <extension>jar</extension>
- <mime-type>application/java-archive</mime-type>
- </mime-mapping>
2. Create a directory on disk D for jsp, html, and jar. Jad files are all lost here). Many articles have been written before configuring tomcat to support methods). Create a time in d: \ jsp. jsp, content: <% = newjava. util. date () %>, open the browser to access http: // yourip: 8080/jsp/time. jsp. The current time indicates that the configuration is successful.
3. in d: \ jsp, create a new directory, and complete the xxx. jad and the corresponding xxx. drop the jar file in it. Pay attention to xxx. fill in the corresponding xxx in the MIDlet-Jar-URL attribute of the jad file. the absolute path of jar. In this example, http: // yourip: 8080/jsp/j2-xxx. jar
4. Create a j2me.html file in d: \ jsp. the content is
- <?html>
- <title>J2ME</title>
- <body>
- <ahrefahref="http://yourip:8080/jsp/J2ME/demos.jad">demos.jad</a>
- <ahrefahref="http://yourip:8080/jsp/J2ME/UIDemo.jad">UIDemo.jad</a>
- <ahrefahref="http://yourip:8080/jsp/J2ME/games.jad">games.jad</a>
