问题描述
我正在尝试向小程序添加库.我正在使用 jnlp + 部署 java javascript.一切似乎都配置正确,但是找不到类(类未找到异常).
I am trying to add libraries to applet. I am using the jnlp + deploy java javascript. Everything seems to be configured correctly, bud the classes are not found (class not found exception).
这是我的代码:
JNLP:
<?xml version="1.0" encoding="UTF-8"?>
<jnlp spec="1.0+" codebase="." href="">
<information>
<title>KeystoreTestApplet</title>
<vendor>Paulie</vendor>
</information>
<resources>
<!-- Application Resources -->
<j2se version="1.6+"
href="http://java.sun.com/products/autodl/j2se"/>
<jar href="KeystoreTestApplet.jar" main="true" />
<jar href="xmlsec-1.4.5.jar" />
<jar href="xml-apis-1.3.03.jar" />
<jar href="xercesImpl-2.9.1.jar" />
<jar href="xalan-2.7.1.jar" />
<jar href="sunpkcs11.jar" />
<jar href="serializer-2.7.1.jar" />
<jar href="commons-logging-api-1.1.jar" />
<jar href="commons-logging-1.1.jar" />
</resources>
<applet-desc
name="KeystoreTestApplet"
main-class="KeystoreJApplet"
width="600"
height="370">
<param name="MAYSCRIPT" value="true"/>
</applet-desc>
<update check="background"/>
<security>
<all-permissions/>
</security>
</jnlp>
HTML:
<script src="deployJava.js"></script>
<script>
var attributes = { codebase:'.', code:'KeystoreJApplet', width:600, height:370} ;
var parameters = {jnlp_href: 'KeystoreTestApplet.jnlp', mayscript: 'true'} ;
deployJava.runApplet(attributes, parameters, '1.6');
</script>
小程序 jar、html 页面和库 jar 位于同一目录中.
The applet jar, html page and the libraries jars are in the same directory.
感谢您的帮助.
推荐答案
我在一个有点不同的地方发现了实际问题.
I have found the actual problem on a little bit different spot.
这些库不包含在 jnlp 文件的路径中,而是包含在清单中.清单路径已由 IDE 指定为 lib/{library}.jar.所以java在不同的目录中搜索jars.
The libraries are not included from the paths in jnlp file, but in manifest. The manifest paths had been specified by IDE as lib/{library}.jar. So java was searching for the jars in a different directory.
