ubuntu linux wtk 安装问题
0.报错说：Failed to extract JavaVersionTester class
解决方案：依次执行
LANG2=$LANG
LANG=sv_SE.ISO8859-1
. wtk.bin(下载下来的wtk）
一步步安装就可以了。
1.报错说：

如果通过命令行直接启动WTK会遇到如下情况：

这些错误是应用WTK及其模拟器采用了Java中的UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());语句来使用系统自身的lookandfeel，而 Ubuntu系统中没有安装对应的主题导致的错误，而目前本人并没有在安装包中找到相关的主题安装内容（注意：不代表不存在，只是本人没有找到而已），如果有哪位同行找到也请发布上来，谢谢。
在当前情况下如何解决这一个问题是关键，这里本人给出了如下解决办法：
首先找到你的WTK的安装目录，在bin中找到ktoolbar和emulator这两个文件，这两个是启动WTK和Emulator的两个启动文件，使用vi或者gedit来对这两个文件进行编辑，在两个文件中的相关位置添加如下一行即可：
－Dswing.systemlaf=”javax.swing.plaf.metal.MetalLookAndFeel” \\
添加后的ktoolbar如下(注意红色标注的那行即可)：
#!/bin/sh
javapathtowtk=/usr/java/jdk1.6.0_05/bin/
PRG=$0
# Resolve soft links
while [ -h “$PRG” ]; do
ls=`/bin/ls -ld “$PRG”`
link=`/usr/bin/expr “$ls” : ‘.*-> (.*)$’`
if /usr/bin/expr “$link” : ‘^/’ > /dev/null 2>&1; then
PRG=”$link”
else
PRG=”`/usr/bin/dirname $PRG`/$link”
fi
done
KVEM_BIN=`dirname $PRG`
KVEM_HOME=`cd $…{KVEM_BIN}/.. ; pwd`
KVEM_LIB=”${KVEM_HOME}/wtklib”
KVEM_API=”${KVEM_HOME}/lib”
export MMAPI_GM_SOUNDBANK=”${KVEM_API}/soundbank.dls”
”${javapathtowtk}java” -Dkvem.home=”${KVEM_HOME}” \\
-Djava.library.path=”${KVEM_HOME}/bin” \\
-Dswing.systemlaf=”javax.swing.plaf.metal.MetalLookAndFeel” \\
-cp “${KVEM_LIB}/kenv.zip:${KVEM_LIB}/ktools.zip:${KVEM_BIN}/JadTool.jar:${KVEM_BIN}/MEKeyTool.jar:${KVEM_LIB}/customjmf.jar:${KVEM_API}/ j2me-ws.jar:${KVEM_BIN}/schema2beansdev.jar:${KVEM_BIN}/j2me_sg_ri.jar:${KVEM_BIN}/jaxrpc-impl.jar:${KVEM_BIN}/jaxrpc-api.jar:${KVEM_BIN}/jaxrpc-spi.jar:${KVEM_BIN}/activation.jar:${KVEM_BIN}/mail.jar:${KVEM_BIN}/saaj-api.jar:${KVEM_BIN}/saaj-impl.jar:${KVEM_BIN}/xsdlib.jar:${KVEM_LIB}/nist-sip-1.2.jar:${KVEM_LIB}/JainSipApi1.1.jar:${KVEM_LIB}/jain-sip-presence-proxy.jar”
com.sun.kvem.toolbar.Main “$@”
修改后的emulator文件内容如下：
#!/bin/sh
javapathtowtk=/usr/java/jdk1.6.0_05/bin/
PRG=$0
# Resolve soft links
while [ -h “$PRG” ]; do
ls=`/bin/ls -ld “$PRG”`
link=`/usr/bin/expr “$ls” : ‘.*-> (.*)$’`
if /usr/bin/expr “$link” : ‘^/’ > /dev/null 2>&1; then
PRG=”$link”
else
PRG=”`/usr/bin/dirname $PRG`/$link”
fi
done
KVEM_BIN=`dirname “$PRG”`
KVEM_HOME=`cd “${KVEM_BIN}/..” ; pwd`
KVEM_LIB=”${KVEM_HOME}/wtklib”
export MMAPI_GM_SOUNDBANK=”${KVEM_HOME}/lib/soundbank.dls”
”${javapathtowtk}java” -Dkvem.home=”${KVEM_HOME}” \\
-Djava.library.path=”${KVEM_HOME}/bin” \\
-Dswing.systemlaf=”javax.swing.plaf.metal.MetalLookAndFeel” \\
-cp “${KVEM_LIB}/kenv.zip:${KVEM_LIB}/ktools.zip:${KVEM_LIB}/customjmf.jar”
com.sun.kvem.environment.EmulatorWrapper “$@” 0
好了，大功告成，现在可以运行WTK和Emulator了，而且还是中文的
