    text
    copied!<p>I asked a <a href="https://stackoverflow.com/questions/2410808/how-do-i-catch-errors-globally-log-them-and-show-user-an-error-page-in-j2ee-app">question</a> along similar lines yesterday as well. In that question I was suggested to have a global filter (which I already had).</p> <p>So I have a JSP like below</p> <pre><code>....code...code ..tags...html...code Object [] res = iBatisDAO.getReport_pging(null,null,0,null); //call to DB ...more code... ...tags...end </code></pre> <p>In the above code I am intentionally passing null's because I want it to fail and when it fails I want it to go to our centralized error page. I have the following in my web.xml</p> <pre><code> &lt;error-page&gt; &lt;exception-type&gt;com.ibatis.common.jdbc.exception.NestedSQLException&lt;/exception-type&gt; &lt;location&gt;/errorpages/Error.jsp&lt;/location&gt; &lt;/error-page&gt; &lt;error-page&gt; &lt;exception-type&gt;org.springframework.dao.DataAccessException&lt;/exception-type&gt; &lt;location&gt;/errorpages/Error.jsp&lt;/location&gt; &lt;/error-page&gt; &lt;error-page&gt; &lt;exception-type&gt;javax.servlet.ServletException&lt;/exception-type&gt; &lt;location&gt;/errorpages/Error.jsp&lt;/location&gt; &lt;/error-page&gt; &lt;error-page&gt; &lt;exception-type&gt;java.sql.SQLException&lt;/exception-type&gt; &lt;location&gt;/errorpages/Error.jsp&lt;/location&gt; &lt;/error-page&gt; &lt;error-page&gt; &lt;exception-type&gt;org.springframework.jdbc.UncategorizedSQLException&lt;/exception-type&gt; &lt;location&gt;/errorpages/Error.jsp&lt;/location&gt; &lt;/error-page&gt; </code></pre> <p>the 'control' comes to the above JSP via a global filter that I have. it has <code>chain.doFilter()</code> wrapped in <code>try/catch</code> block. When <code>exception</code> happens it redirects to Error.jsp.</p> <p>When the error happens...it is not being caught by the centralized error page and neither is it caught by the filter. I think filter is not catching it because when filter 'calls' the jsp...there IS no error yet. </p> <p>I know call to DB is BAD inside a JSP but I am dealing with lot of legacy code. </p> <p>What can I do to have errors go to centralized error page in this scenario? Also, the JSP does not have the error page imported. I would not want the option of importing an error page to all JSP's I want to have a more general solution. </p>
