Hi I have seen that DefaultHref always adds parameters to the request also when these parameters are already present; this means that the querystring can become too long (above all in Portal Sy). I modified the java code of toString method. I post the modified method here. I used it in my project and it seems to work.
public String toString() { StringBuffer buffer = new StringBuffer(30); buffer.append(this.url); if (this.parameters.size() > 0) { buffer.append('?'); Set parameterSet = this.parameters.entrySet(); Iterator iterator = parameterSet.iterator(); List alreadyAddedKey = Collections.synchronizedList(new ArrayList()); while (iterator.hasNext()) { Map.Entry entry = (Map.Entry) iterator.next(); Object key = entry.getKey(); Object value = entry.getValue(); if (value == null) { //According to me this is wrong; if value of parameter is null i should put it null //buffer.append(key).append('='); // no value //nothing to do } else if (value.getClass().isArray()) { Object[] values = (Object[]) value; for (int i = 0; i < values.length; i++) { if (i > 0 && !"".equals(values[i]) && !alreadyAddedKey.contains(key)) { buffer.append(TagConstants.AMPERSAND); } if( !"".equals(values[i]) && !alreadyAddedKey.contains(key)){ buffer.append(key).append('=').append(values[i]); alreadyAddedKey.add(key); } } } else { if( !"".equals(value) && !alreadyAddedKey.contains(key) ){ buffer.append(key).append('=').append(value); alreadyAddedKey.add(key); } } if (iterator.hasNext()&& !buffer.toString().endsWith(TagConstants.AMPERSAND)) { buffer.append(TagConstants.AMPERSAND); } } } if (this.anchor != null) { buffer.append('#'); buffer.append(this.anchor); } return buffer.toString(); } I hope this can be usefull Regards, Angelo. ------------------------------------------------------------------------------ The Planet: dedicated and managed hosting, cloud storage, colocation Stay online with enterprise data centers and the best network in the business Choose flexible plans and management services without long-term contracts Personal 24x7 support from experience hosting pros just a phone call away. http://p.sf.net/sfu/theplanet-com _______________________________________________ displaytag-user mailing list displaytag-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/displaytag-user
