<TD>还是不行啊！不知道是不是我理解错误，代码如下：
<BR><BR>String[] runcardResult = new String [xr.getRuncard().length];
<BR>String[] runcard2ISO = new String [runcardResult.length]; //转为ISO8859_1字符集的流程名
<BR>runcardResult = xr.getRuncard();
<BR>String runcard = new String (request.getParameter("runcard"));//用于显示
<BR>if(runcard ==null){
<BR> runcard=runcardResult[0];
<BR> }
<BR><BR>String runcardToQuery = new String (runcard.getBytes("8859_1"));//用于查询
<BR><BR>String[] stepnameResult = new String [xr.getStepname(runcardToQuery).length]; //流程名
<BR>String[] stepname2ISO = new String [stepnameResult.length]; //转为ISO8859_1字符集的流程名
<BR>stepnameResult = xr.getStepname(runcardToQuery);
<BR>String stepname = new String(request.getParameter("stepname"));//用于显示
<BR>if(stepname ==null){
<BR>stepname=stepnameResult[0];
<BR> }
<BR><BR><BR><BR>还是[color=red:4bcd9f061c]NullPointer[/color:4bcd9f061c]例外！<BR><BR></TD></TR>
