    <p>I'm trying to post a request to download a pdf file in java. I'm using - trying to fix cause the method is changed - someone else's code and, for what I've seen, before requesting the pdf file via a web service, a check for the content type is made. If the content-type requested is ok, then a call to the service to download the pdf file is made.</p> <p>This is the method that checks for the content type:</p> <pre><code>public boolean checkContentType(String serviceName, Map&lt;String, String&gt; params, String contentType) { params.put(PARAM_SERVICE, serviceName); if(log.isDebugEnabled()) { log.debug("checkContentType for serviceName: " + serviceName + " - Params: " + params + " - contentType: " + contentType); } HttpClient httpclient = new HttpClient(); GetMethod get = new GetMethod(basicUrl); get.setQueryString(ParameterUtil.getValuePairs(params)); log.info(get.getQueryString()); try { httpclient.executeMethod(get); if (get.getStatusCode() == HttpStatus.SC_OK) { String respContentType = get.getResponseHeader("Content-Type").getValue(); log.info("Request Content type [" +contentType + "] is not in response content type: [" + respContentType + "]"); log.info(String.valueOf(contentType != null)); log.info(String.valueOf(StringUtils.containsIgnoreCase(respContentType, contentType))); return contentType != null &amp;&amp; StringUtils.containsIgnoreCase(respContentType, contentType); } else { log.error("Response status code KO: [" + get.getStatusCode() +"] from url: " + basicUrl + " with querystring: " + get.getQueryString()); } } catch (Exception e) { log.error("Unable to get http response from url: " + basicUrl + " with querystring: " + get.getQueryString() + ". Ex Msg:" + e.getMessage()); } finally { get.releaseConnection(); } return false; } </code></pre> <p>When Content-type is 'pdf' I get false on the second condition, but how do I know what Content-type should be set? I get this log: <code>Request Content type [pdf] is not in response content type: [text/plain;charset=UTF-8]</code>. </p> <p>I've also tried to skip the content type check and go request the pdf immediately, but after waiting for some time I get a 16 kb pdf that I can't open. I've tried to set the content type to text/plain;charset=UTF-8 but I still get that log.</p> <p>Shouldn't it be PDF since I'm downloading a pdf, or should I set somewhere in the code that I expect a pdf content type?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
